    Scotch whisky is one of the most tightly regulated spirits categories in the world. The Scotch Whisky Regulations 2009 govern everything from distillation and maturation to labelling and packaging — and for glass packaging buyers, that regulatory framework creates a set of hard requirements that do not apply in most other spirits categories. Get the bottle specifications wrong, and you risk failing a bottling line qualification, an SWA audit, or both.

    This guide is written for B2B glass packaging buyers, brand packaging managers, and procurement teams working with Scotch whisky producers and importers. It covers the five legally defined Scotch categories, how each shapes glass selection decisions, the standard retail formats for EU and US markets, glass weight and strength expectations by tier, neck finish and closure compatibility, decoration capabilities for premium expressions, and a practical checklist for sourcing Scotch-compliant bottles from Chinese manufacturers.

    For context on the broader GI regulatory landscape — which places Scotch alongside Cognac, Irish Whiskey, and Bourbon — see our guide to EU Geographical Indication spirits packaging rules. This article goes deeper on the Scotch category specifically: the glass specifications, market conventions, and supplier checklist that translate that regulatory framework into practical procurement decisions.

    Quick Answers: Scotch Whisky Glass Packaging Basics

    What bottle size is the EU standard for Scotch whisky retail?

    700mL is the mandated standard retail format for Scotch whisky sold in the EU and UK, as set by EU Regulation 2019/787 on spirits definitions and labelling. The 750mL format used in the US is not an acceptable EU retail unit — EU distributors and retailers will not accept 750mL for domestic sale. For travel retail (airport duty-free) channels, alternative formats including 1L, 500mL, 350mL, and miniatures (50mL, 100mL) are also accepted and represent significant revenue for Scotch producers.

    Does Scotch whisky have to be bottled in Scotland?

    For Single Malt Scotch Whisky, yes. The Scotch Whisky Regulations 2009 require that Single Malt must be distilled, matured, and bottled in Scotland. For other Scotch categories — Blended Scotch, Single Grain, Blended Malt, and Blended Grain — bulk export for overseas bottling is permitted under certain conditions, though all labelling requirements still apply. In practice, most major Scotch producers bottle all categories in Scotland regardless of category-specific requirements.

    What is the SWA's role in Scotch whisky packaging?

    The Scotch Whisky Association (SWA) enforces the Scotch Whisky Regulations 2009, monitors global labelling and packaging compliance, and pursues legal action against infringement. While the SWA does not publish a single binding packaging specification document, its technical guidance sets strong market conventions for bottle format, label area dimensions, and closure type that virtually all Scotch producers follow. Deviating from these conventions creates both regulatory and reputational risk that trade buyers and importers take seriously.

    What glass colour is most common for Scotch whisky bottles?

    There is no regulatory requirement for a specific glass colour. Amber glass is traditional for aged Single Malts, offering UV protection and visually signalling maturation heritage. Clear (flint) glass is common where the whisky's natural colour is part of the brand narrative. Dark green and black glass appear in limited editions and prestige expressions. The colour choice is driven by brand positioning and the specific expression's visual identity — not by statutory requirements — and should be confirmed with the closure and label application team as part of bottle specification.

    Is there a minimum glass weight required for Scotch whisky bottles?

    No minimum weight is set by regulation, but market convention is strong. Standard 700mL Scotch bottles typically range from 380g to 600g; premium Single Malt expressions regularly use 600g–850g bottles; ultra-premium and limited-edition releases can exceed 900g. A lightweight bottle in the 280–350g range signals entry-level positioning and is commercially incompatible with the premium shelf expectations of the Single Malt category. Weight is one of the first signals a retail buyer reads before the liquid is assessed, and specifying below category convention has direct consequences for placement and pricing perception.

    Why Scotch Is a Uniquely Regulated Spirits Category

    Unlike most spirits categories, Scotch whisky operates under statutory protection backed by both UK domestic law and EU GI law independently. The Scotch Whisky Regulations 2009 — which remain in full force in the UK post-Brexit, with equivalent GI protection within the EU provided by Regulation 2019/787 — define five legally distinct Scotch categories, each with specific production, maturation, and labelling requirements. For glass packaging buyers, understanding these five categories matters because they carry different market conventions for bottle weight, format, decoration level, and closure type.

    The five legally defined categories are:

    • Single Malt Scotch Whisky: Made from 100% malted barley at a single Scottish distillery, matured for a minimum of three years in Scotland in oak casks of no more than 700 litres, and — critically for glass supply chains — bottled in Scotland.

    • Single Grain Scotch Whisky: Produced at a single Scottish distillery from grains other than (or in addition to) malted barley. Bulk export for overseas bottling is permitted.

    • Blended Malt Scotch Whisky: A blend of Single Malt whiskies from two or more Scottish distilleries.

    • Blended Grain Scotch Whisky: A blend of Single Grain whiskies from two or more Scottish distilleries.

    • Blended Scotch Whisky: A blend of at least one Single Malt and at least one Single Grain Scotch whisky. This is the largest commercial category by global volume.

    From a glass packaging standpoint, all five categories share the same EU standard retail format (700mL) and the same mandatory labelling requirements. What differentiates them in packaging terms is almost entirely commercial convention: Single Malt expressions command significantly heavier, more elaborately decorated glass; Blended Scotch spans a wide price tier from standard off-trade retail to premium gifting. The SWA monitors how each category is presented globally, and packaging that blurs category boundaries — presenting a Blended Scotch in a way that implies Single Malt provenance — is treated as a potential regulatory violation. Glass shape, closure type, and label hierarchy all factor into that assessment.

    Scotch Whisky Regulations 2009: Packaging Implications by Provision

    Bottling Location Requirement (Single Malt)

    The requirement that Single Malt Scotch Whisky be bottled in Scotland has direct and practical implications for glass supply chains. Bottles must be shipped from the manufacturing site — whether UK-based or imported from China or the EU — unfilled to Scotland, where filling, closing, and labelling takes place at the distillery or contracted Scottish bottling plant. Any glass quality issue discovered on the bottling line cannot be resolved by rework at an overseas fill-and-label facility. Bottles must arrive dimensionally compliant and damage-free, ready to run on existing line equipment from day one of production. This reality makes pre-production sample qualification on the actual Scottish bottling line a non-negotiable step for any new glass mold or first-time supplier engagement.

    Minimum ABV and Mandatory Label Information

    All Scotch whisky must be bottled at a minimum 40% ABV. Mandatory label information includes: the category name (e.g., "Single Malt Scotch Whisky"), the name of the distillery or producing company, country of origin ("Product of Scotland"), and — if displayed — an age statement reflecting the youngest whisky in the bottle. From a glass specification perspective, this mandatory copy requires a label panel of sufficient area and surface consistency to accommodate the text at legible font sizes without distortion across the bottle's curvature. Label area dimensions — front panel width and height, curvature radius, neck label dimensions — are confirmed between the glass supplier, label printer, and label application equipment before mold approval is issued.

    Age Statement Rules

    Age statements are optional for NAS (No Age Statement) expressions but, when used, must reflect the youngest component in the bottle. Premium Single Malts carry age statements of 10, 12, 15, 18, 21, 25 years or more — and the age statement is typically displayed prominently on the front label panel. On ultra-premium expressions, the age may also appear as embossed glass text or ACL-printed numerals directly on the bottle. The bottle must provide a consistently curved or flat label area that allows the age statement to display cleanly at shelf, without the text distorting around an aggressive shoulder curve or embossed design element.

    EU and UK GI Protection Post-Brexit

    Post-Brexit, Scotch whisky retains full GI protection under UK domestic law (The Scotch Whisky Regulations 2009) and under EU law through Regulation 2019/787 independently. For glass packaging buyers supplying Scotch producers that export to both markets, this means both the EU 700mL and UK 700mL formats are aligned — but the US-destined 750mL requires a separate specification and TTB COLA approval. Our EU spirits glass packaging compliance guide covers the broader market-entry documentation requirements for spirits brands entering the EU bloc, including imported Scotch from non-EU territories.

    Standard Bottle Formats: 700mL, 750mL and Dual-Market Strategy

    The format decision is the most consequential early glass packaging specification decision for any Scotch whisky producer or importer. The EU and UK markets use 700mL as the mandatory retail standard; the US market requires 750mL for TTB approval. These formats are not interchangeable — a 700mL bottle cannot be legally sold at retail in the US as a standard spirits unit, and a 750mL bottle will be rejected by EU and UK trade buyers for domestic retail placement.

    700mL: The EU, UK and Global Scotch Default

    700mL is mandated for spirits GIs including Scotch whisky under EU Regulation 2019/787, and is maintained as the UK domestic standard post-Brexit. All Scottish domestic retail, EU export, and duty-paid import into EU member states must use 700mL as the primary format. The 700mL format is also the standard for travel retail at EU airports and a significant format in Middle East, Asia-Pacific, and Latin American duty-free channels. For producers targeting primarily European and global export markets outside the US, 700mL is the unambiguous starting point.

    750mL: The US Market Requirement

    For Scotch whisky entering the US market, 750mL is the TTB-approved standard retail format. The TTB (Alcohol and Tobacco Tax and Trade Bureau) defines approved bottle sizes for spirits under 27 CFR Part 5; the approved list includes 50mL, 100mL, 200mL, 375mL, 750mL, 1L, and 1.75L. A COLA (Certificate of Label Approval) submission to TTB must specify the bottle size, and a 700mL bottle cannot be substituted for a 750mL in a US COLA filing. Use the Spirits Bottle Size Calculator to cross-check US and EU format volumes, review the complete TTB approved size list, and calculate fill line equivalents across both unit systems.

    Dual-Market Strategy: Two Molds vs Shared Platform

    For Scotch producers distributing to both EU/UK and US markets, the standard approach is two separate molds — a 700mL and a 750mL — sharing the same brand visual identity and silhouette family but with adjusted body height, shoulder profile, and label panel geometry. This maintains full format compliance in both markets and allows label proportions to remain consistent with the bottle's physical dimensions in each format.

    For entry-level blended expressions, some producers attempt fill height adjustment within a single shared mold to defer a second tooling investment. This is commercially viable for mass-market blends where label panel proportion is less critical, but it is incompatible with premium Single Malt positioning — the label geometry mismatch between 700mL and 750mL fill heights creates visual inconsistencies at shelf that undermine premium brand identity at the exact moment the buyer is evaluating the bottle.

    Travel Retail and Alternative Formats

    Travel retail is a major revenue channel for Scotch whisky, and airport duty-free shelves carry a wide format range. The 1L format is particularly significant globally — at US international terminals, EU airports, and duty-free channels across the Middle East and Asia-Pacific. The full travel retail Scotch format range includes 1L, 700mL, 500mL, 350mL, 200mL, 100mL, and 50mL miniatures, often presented in combination packs and gift sets. Each format requires its own glass specification, and for travel retail supply, pack dimensions must also be designed to accommodate presentation packaging (tubes, tins, gift boxes) and IATA dangerous goods compliance requirements for air transport.

    Glass Weight, Strength and Dimensional Quality Expectations

    Glass weight in Scotch whisky packaging functions as both a practical engineering specification and a brand positioning signal. The Scotch market has developed strong weight conventions across category tiers — conventions that retail buyers, trade buyers, and end consumers read as reliable proxies for quality and price positioning. Specifying outside these conventions carries commercial risk that cannot be resolved by label or closure choices alone.

    Weight Conventions by Category Tier

    Expression Tier

    Typical Bottle Weight (700mL)

    Typical Use Case

    Entry-level Blended Scotch

    280–420g

    Standard off-trade retail blends

    Mid-range Blended / Standard Single Malt

    420–600g

    10–12yr Single Malts; premium blends

    Premium Single Malt (15–21yr)

    600–780g

    Age-stated premium shelf expressions

    Ultra-premium and Limited Edition

    780g–1,000g+

    25yr+, collector releases, prestige gift sets

    Specifying a bottle weight below category convention has direct commercial consequences: a premium-priced Single Malt in a 350g bottle will not survive retail buyer evaluation regardless of the liquid quality or label design. HUIHE supplies glass bottles across the full Scotch weight range and produces pre-production samples at the specified target weight for bottler evaluation before full production commitment.

    Mechanical Strength: Automated Bottling Line Requirements

    While Scotch whisky does not generate significant internal pressure (unlike sparkling wine), the glass must withstand the mechanical stresses of high-speed automated bottling lines — including internal pressure from filling equipment, torque stress from ROPP capping machines, and impact forces from conveyor transfer and carton packing. For automated Scottish bottling lines operating at 6,000–12,000 bottles per hour, internal pressure resistance per ISO 7458 typically requires a minimum burst pressure of 2.0–2.5 bar for standard expressions, with premium bottles generally tested at 3.0 bar. Exact requirements should be confirmed with the bottling plant's quality manager before glass specification is finalised, as they vary by filler type, capping equipment, and line speed.

    Dimensional Tolerance Requirements

    High-speed bottling lines require tight dimensional consistency across every bottle in a production run. Variations that would be unnoticed in manual bottling cause systematic failures at line speed. The key dimensional parameters for Scotch whisky bottle specification are:

    • Verticality (lean): ≤ 2mm deviation per 300mm bottle height — leaning bottles cause capping failures and label misalignment at speed

    • Ovality: ≤ 0.8% of body diameter — excessive ovality disrupts labeller clamp registration

    • Neck diameter, ROPP finish: ± 0.3mm from nominal — critical for rolling die engagement and seal integrity

    • Cork bore diameter: ± 0.2mm — critical for airtight cork engagement without fragmentation risk on insertion

    • Bottle height: ± 1.5mm — affects carton pack-out configuration and conveyor transfer alignment

    • Brimful capacity: ± 1.5% of nominal volume — affects fill-to-label accuracy on volumetric fillers

    These tolerances should be specified in the glass bottle drawing and confirmed via dimensional inspection report per production batch. HUIHE verifies dimensional compliance through in-process sampling with calibrated gauges and provides batch-level inspection reports as standard documentation.

    Neck Finish Types and Closure Compatibility

    The neck finish is the interface between the glass bottle and the closure, and for Scotch whisky it determines not only sealing integrity over extended shelf life but also the tactile premium signal the consumer experiences at opening. Each finish type carries distinct positioning associations and technical requirements that must be cross-referenced with the closure supplier before mold approval.

    Cork Finish (T-Cork and Bar Top)

    Cork closures are strongly associated with premium and craft Scotch expressions, and their tactile feel at opening is a deliberate part of the brand experience for Single Malt producers. The glass neck for cork closures uses a smooth-bore internal profile — no threads — with an internal bore diameter precisely matched to the cork diameter. Typical bore dimensions range from 18.5mm to 21.5mm internal diameter depending on cork grade and length. The bore taper angle must match the cork profile to ensure airtight engagement without requiring excessive insertion force, which risks cork fragmentation and particle contamination. A clean, burr-free bore is essential: any mold seam or glass defect inside the bore can cause cork damage on insertion and create sealing failures.

    T-cork closures — where a decorative cross-handle in wood, metal, or ceramic sits above the cork body — are widely used on premium Single Malt expressions. The glass neck height above the shoulder and the external neck diameter must accommodate the T-cork body with sufficient clearance for the cap's material and diameter. These dimensions are confirmed between the glass supplier, closure supplier, and bottling line operator as part of the bottle development brief.

    ROPP Screw Cap (Roll-On Pilfer Proof)

    ROPP screw caps are the dominant closure for standard and mid-range blended Scotch expressions, offering consumer convenience, tamper evidence, and compatibility with high-speed automated capping. The glass neck finish for ROPP uses standardised thread dimensions — the most common for spirits being 28mm BG (Bard Groove) and 30mm BG — with a defined thread count, pitch, and start position that allows the ROPP rolling dies to form a leak-free, tamper-evident seal. ROPP lines run at high speed, typically 3,000–10,000 closures per hour, making neck finish dimensional consistency especially critical. Variations of ± 0.3mm in neck diameter can cause seal failures or machine jams that bring production to a halt.

    Synthetic Cork and Wax Seal

    Synthetic corks, made from LDPE or composite materials, are used by some premium Scotch producers as a consistent alternative to natural cork, eliminating the cork taint (TCA) risk associated with natural closures while preserving the traditional opening experience. From a glass specification perspective, synthetic corks use the same bore-finish neck profile as natural cork — internal bore diameter, taper angle, and bore smoothness all apply. Wax sealing, applied post-filling as a secondary aesthetic seal over a primary cork closure, is associated with certain prestigious Scotch expressions and adds a tactile premium element that is recognisable at retail and in gifting contexts. The neck shoulder geometry determines where the wax drip line falls, and this is typically confirmed in a bottling trial before full production approval.

    Decoration Options for Scotch Expressions

    Decoration is where Scotch whisky packaging most visibly differentiates across tiers and categories. The Single Malt premium segment has pushed glass decoration to high levels of craft — combining frosted textures, deep mould embossing, multi-colour ACL printing, and metallic foil accents to produce bottles that function as collector objects as much as liquid containers. Understanding what is technically achievable and commercially appropriate at each tier is essential for packaging teams briefing glass suppliers.

    ACL (Applied Colour Label) Ceramic Screen Printing

    ACL printing fuses vitreous ceramic inks directly onto the glass surface through a kiln-firing process, producing decoration that is chemically bonded to the glass — scratch-resistant, permanent, and unaffected by condensation or refrigeration. For Scotch whisky, ACL is used for brand marks, heritage pattern motifs, tartan textures, accent text elements, and colour fills across premium and mid-range expressions. The process achieves fine detail at approximately 0.8mm minimum line width and is available in a full ceramic colour palette including metallics, opaques, and translucents. Multiple print passes allow layered and overprinted effects. HUIHE operates ACL printing as a standard production capability and provides colour matching samples before full-run commitment.

    Mould-Blown Embossing and Relief Textures

    Embossing — raised or recessed relief patterns built into the mould — is one of the most distinctive tactile features in premium Scotch packaging. Distillery crests, tartan textures, script text, geometric patterns, and regional motifs are commonly embossed on bottle bodies, shoulders, and bases. Since embossing is integral to the mould, tooling cost is incurred once at the mould development stage; per-unit production cost is zero thereafter. Deep embossing creates tactile differentiation that paper labels cannot replicate and is strongly associated with ultra-premium and limited-edition positioning. Emboss depth and undercut angle must be specified carefully to ensure clean mould release without distortion during production.

    Chemical Frosting and Acid Etching

    Frosted glass effects — produced by acid etching or abrasive blasting — create a matte, light-diffusing surface that contrasts effectively with clear or coloured label panels. Some Single Malt expressions use full-body frosting; others apply frosted bands or accent panels as design elements. Acid etching is applied as a post-forming surface treatment, adding a production step and per-unit cost. It is best suited to medium and larger production volumes where the cost premium is justified by the expression's positioning and price point. Frosted glass also provides a modest UV-filtering benefit, relevant for whiskies displayed under retail lighting.

    Foil Hot-Stamping and Metallic Elements

    Hot-stamping applies metallic foil to glass surfaces using heated dies, producing sharp-edged gold, silver, bronze, or holographic metallic elements. For Scotch whisky, hot-stamping is commonly used for brand crest medallions, age statement frames, decorative bands, and signature marks. It can be applied to bare glass or layered over ACL-printed surfaces for multi-material decoration. Adhesion durability is the critical quality parameter — foil bond strength must be verified under condensation and refrigeration conditions typical for travel retail display and on-trade bar environments. HUIHE conducts adhesion peel testing on hot-stamp samples before full production approval as standard practice.

    Sourcing Scotch-Compliant Bottles from China: Practical Checklist

    Chinese glass manufacturers supply a significant share of global Scotch whisky glass, including standard formats for established distilleries, custom moulds for independent bottler (IB) expressions, and duty-free travel retail formats. The key to a successful sourcing engagement is precise upfront specification and comprehensive compliance documentation. Our full guide to sourcing custom spirits glass bottles from China covers the end-to-end procurement process; the checklist below focuses on the Scotch-specific requirements that must be addressed before production begins.

    Pre-Production Specification Checklist

    Specification Item

    What to Confirm Before Mould Approval

    Target bottle weight

    Minimum and nominal weight (g), aligned with expression tier positioning

    Decoration specification

    ACL colour count and artwork file; embossing area and depth; frosting zones; foil elements — all confirmed in 2D engineering drawing before mould cut

    Label area dimensions

    Front, back, and neck label panel dimensions and curvature radius; confirmed with label printer and label application equipment for compatibility

    Dimensional tolerances

    Verticality, ovality, neck diameter, height, and brimful capacity — all aligned with Scottish bottling line equipment specifications

    Packing and freight format

    Carton configuration, pallet pattern, and interleaving material for long-haul sea freight to Scottish bottling plant; inner packaging must prevent contact damage in transit

    Compliance Documents to Request

    • EU Declaration of Conformity (Regulation 1935/2004): Required for all glass bottles supplied for food and beverage contact use in EU and UK markets. Confirms that the glass composition meets migration limits for hazardous substances under the applicable framework. HUIHE provides this declaration as standard documentation with every export shipment.

    • REACH SVHC Declaration: Confirms absence of Substances of Very High Concern above 0.1% w/w in the glass article, aligned with the current ECHA candidate list (253 substances as of February 2026).

    • ISO 9001 Certificate: Confirms the manufacturer's quality management system meets international standards. HUIHE holds ISO 9001 certification; the current certificate is available on request.

    • Dimensional Inspection Report (per batch): Documents key dimensions — height, body diameter, neck diameter, fill capacity, verticality, ovality — against agreed tolerances for each production run.

    • Third-party heavy metal migration test (recommended for premium expressions): SGS or equivalent EN ISO 7086 test for lead and cadmium migration, particularly recommended for expressions that may be subject to spot testing at import into EU, UK, or US markets.

    Pre-Production Samples and Line Qualification

    For any new mould or first-time supplier engagement, request a pre-production sample (PPS) run of 50–100 bottles before committing to full production. For Single Malt producers bottling in Scotland, arrange for these samples to be tested on the actual Scottish bottling line — filler, capper, and labeller — before the main production run is approved. Provide your glass supplier with the bottling plant's equipment specifications: filler model, capper type and model, labeller type, and line speed in bottles per hour. This data allows dimensional targets to be calibrated precisely to your bottling line's tolerances rather than to generic industry standards. HUIHE routinely provides PPS runs for new mould qualifications and issues full dimensional inspection data for each PPS batch as part of the qualification package.

    Frequently Asked Questions

    What documentation do I need from a glass supplier to satisfy SWA packaging audits?

    For SWA audit purposes, request the following from your glass supplier: an EU Declaration of Conformity under Regulation 1935/2004 confirming food contact compliance; a per-batch dimensional inspection report verifying bottle height, body diameter, neck finish dimensions, and fill capacity against agreed tolerances; a REACH SVHC compliance declaration aligned with the current ECHA candidate list; and an ISO 9001 certificate confirming quality management system status. For premium expressions subject to spot testing at market entry, add a third-party heavy metal migration test report from SGS or equivalent. HUIHE provides all standard compliance documents as part of the regular shipment package and can issue a dedicated Scotch-format supplier declaration on company letterhead where required by the auditing body.

    How do I specify a Scotch bottle if I need to supply both the EU (700mL) and the US (750mL) markets simultaneously?

    The standard approach for dual-market supply is two separate moulds — one optimised for 700mL and one for 750mL — sharing the same brand silhouette and visual identity but with adjusted body height, shoulder profile, and label panel dimensions. For entry-level blended expressions, some producers use fill height adjustment within a single shared mould to defer a second tooling investment, but this creates label proportion inconsistencies that are commercially incompatible with premium Single Malt positioning. If you are launching a premium brand across both markets simultaneously, budget for two mould investments from the outset. Mould tooling cost is typically amortised over 5,000–10,000 units per format, making it viable even at relatively modest initial volumes.

    Can I use the same bottle mould for Single Malt and Blended Scotch expressions from the same producer?

    The Scotch Whisky Regulations 2009 do not prohibit sharing a mould across categories, and some smaller producers do this as a cost management measure. However, market convention strongly differentiates Single Malt and Blended Scotch at the packaging level. Using an identical bottle body for both categories makes it harder to communicate the premium positioning of the Single Malt and may invite SWA scrutiny if the shared presentation creates consumer confusion about category boundaries. The standard solution is a consistent brand design language — shared colour palette, typography style, label layout logic — applied to distinct bottle silhouettes for each category tier. This maintains brand family coherence while clearly differentiating products at point of sale.

    What happens if my glass bottles fail dimensional tolerance during line qualification at a Scottish bottling plant?

    Line qualification failure typically results in the batch being rejected and returned to the supplier — a significant cost in two-way freight, restocking, and production schedule delay. For Single Malt producers who must bottle in Scotland, the risk is compounded by the lead time required to produce and ship replacement glass from the manufacturing site. To eliminate this risk, conduct a pre-production sample run of 50–100 bottles and test them on the actual bottling line before committing to full production. Provide your glass supplier with the bottling plant's complete equipment specifications — filler model, capper type, labeller configuration, and line speed in bottles per hour — so dimensional targets can be calibrated to your specific equipment's tolerances rather than to generic published standards. HUIHE routinely conducts PPS runs for distillery line qualification and provides full dimensional inspection data for each PPS batch upon request.
