EU vs US Glassware Compliance: What Importers Need to Know

A glass jar with a bamboo lid and silicone seal is not the same regulatory object as a plain glass tumbler. Neither is a decorated drinking glass with enamel near the rim the same as a clear storage container. EU and US rules differ not only in limits and test methods, but in how they define what counts as the regulated product. The buyer’s first task is not to collect certificates — it is to identify which components contact food, under what conditions, and in which market.

Most importers approach compliance backwards. They ask the supplier for “EU certificates” or “FDA approval,” then try to match whatever documents arrive against the product. The more reliable sequence is the reverse: define the product configuration and intended use first, then determine which regulatory framework applies, then request the specific test evidence that framework requires.

This article provides a decision framework rather than a certificate checklist. The goal is to help buyers determine what is actually required for their product, in their market, rather than collecting documents that may not apply.

Step 1 — Classify the Product Before Looking at Any Regulation

Regulatory requirements follow product classification and intended use. Two buyers can import visually identical glass jars and face different requirements because one sells them for dry-goods storage and the other for liquid food contact.

The classification questions are:

Does the product contact food at all? A candle holder, a decorative vase, or a glass ornament does not fall under food-contact regulation. Food-contact migration testing does not apply. Packaging and labelling requirements may still apply, but the compliance file looks different from a food container.

Which surfaces contact food? For a drinking glass, the interior and the lip. For a storage jar, the interior, the underside of the lid, and the seal. For a bottle with a narrow neck, the interior surface and the closure.

What are the contact conditions? Room-temperature dry goods, refrigerated liquids, hot-fill, oven use, and repeated dishwasher exposure all change the test conditions required. A migration test conducted under cold-water conditions does not demonstrate compliance for a product intended for hot tea or acidic foods.

Is the product a single material or a composite? A plain glass body is one regulatory subject. A glass jar with a metal lid, a silicone gasket, and an external decoration is a multi-material article. Each food-contact component may fall under different testing requirements.

Only after these four questions are answered does it make sense to look at the EU or US regulatory framework. Starting with the framework before the classification is how buyers end up with test reports that describe the wrong product.

Step 2 — Understand What the EU Framework Actually Requires

The EU approach to food-contact glassware operates on two levels: a general framework that applies to all food-contact materials, and national measures that fill gaps where EU-level harmonisation does not exist.

The framework regulation. Regulation (EC) No 1935/2004 establishes the general requirement: food-contact materials must not transfer constituents to food in quantities that could endanger human health, cause unacceptable changes in food composition, or deteriorate taste and odour. This applies to glass, ceramics, plastics, and all other food-contact materials.

Good manufacturing practice. Commission Regulation (EC) No 2023/2006 sets out GMP rules for food-contact materials. It applies to all stages of manufacture, processing, and distribution, up to but excluding the production of starting substances. For glassware importers, this means the factory should operate a documented quality assurance system covering the production of the food-contact article. GMP is a process requirement, not a product test.

National measures. Glass is not harmonised at EU level in the same way as plastics. This means specific migration limits for lead and cadmium from glassware are set by national measures adopted under Article 6 of Regulation 1935/2004. Denmark, for example, requires ceramics, enamelled articles, and glassware placed on its market to comply with the migration limits for lead and cadmium set out in Annex 5 of its national order. Other member states have their own national provisions. The practical implication is that a product compliant in one EU market may not automatically satisfy the specific national measure of another.

What importers should request for the EU market. A Declaration of Compliance (DoC) is a common document request, confirming that the product complies with the applicable framework and national measures. For glassware specifically, the relevant test evidence is typically a migration test report under ISO 7086-1 or an equivalent national method, covering lead and cadmium release from the food-contact surface. For decorated products, the report must also cover the decoration where it contacts food or the lips.

Germany’s LFGB. LFGB (Lebensmittel-, Bedarfsgegenstände- und Futtermittelgesetzbuch) is the German national food and feed code. It is widely used across Europe as a de facto benchmark. For glassware, LFGB testing covers heavy metal migration and adds a sensory requirement — the article must not alter the taste or odour of food under defined conditions. The sensory test is a distinguishing feature of LFGB that ISO migration standards do not include. LFGB is not an EU-wide certification; it is a German national standard that many European buyers accept as evidence of compliance with EU framework requirements.

Step 3 — Understand What the US Framework Actually Requires

The US approach differs from the EU in a way that often confuses importers. The FDA does not “approve” glassware. It regulates food-contact substances under the Federal Food, Drug, and Cosmetic Act, and glass occupies a particular position in that framework.

Glass as GRAS. The FDA classifies glass as Generally Recognized as Safe (GRAS) for food and beverage contact. This status is based on glass’s long history of safe use as a food-contact material before 1958. The Glass Packaging Institute states that glass is the only packaging material accepted by the FDA as GRAS for food and beverage contact. For plain, undecorated glass, this means no pre-market approval is required for the glass body itself.

What GRAS does not cover. GRAS status applies to the glass composition, not automatically to every component of a finished glass product. Decorations applied to the glass surface — enamels, paints, printed designs — are not covered by the glass GRAS status. Metal lids, plastic caps, silicone gaskets, and wooden lids are separate materials with their own food-contact requirements. A glass jar may contain GRAS glass and still fail FDA compliance if the lid coating contains leachable lead above the applicable limit.

Compliance Policy Guides. The FDA’s Compliance Policy Guides (CPGs) set leachability limits for lead and cadmium from food-contact surfaces. CPG 7117.06 restricts extractable cadmium, and CPG 7117.07 restricts extractable lead from imported and domestic ceramicware. These guides apply to cups, mugs, pitchers, and hollowware used in the preparation, serving, or storage of food. For decorated glassware, ASTM C927 provides the specific test method for lead and cadmium extracted from the lip and rim area of glass tumblers decorated with ceramic glass enamels.

California Proposition 65. Products sold in California face an additional layer. Lead is listed under Proposition 65 as a chemical known to cause reproductive harm. Enforcement actions have targeted leaded crystal glassware and decorated glassware. Buyers selling into California must either demonstrate that the product meets the relevant exposure thresholds or apply the required warning.

What importers should request for the US market. For plain glass articles, the GRAS status of glass means the primary compliance question is whether any decoration or non-glass component leaches lead or cadmium above FDA limits. For decorated drinking glasses, request a test report under ASTM C927 covering the lip and rim area. For jars and containers with lids or seals, request migration test evidence for each food-contact material. “FDA compliant” as a supplier statement is not sufficient — the test report must identify the tested configuration.

Step 4 — Address Composite Products Component by Component

This is where the EU and US frameworks both become more demanding, and where many compliance files fail.

A glass jar with a bamboo lid and silicone gasket is a multi-material article. When glass or ceramic articles are decorated with enamels or paints, and these decorations may contact food or the lips, several countries require tests not only on the glass substrate but also on the decoration itself. Where articles are made of more than one material — jars with rubber gaskets, or with plastic caps — the tests required to demonstrate compliance also involve the non-glass components.

Lids, gaskets, and closures. For caps, lids, gaskets, and similar sealing articles, EU rules specify that where the intended use is known, these articles must be tested by applying them to the containers for which they are intended, under closure conditions corresponding to normal or foreseeable use, and on the assumption that the sealing article is in contact with a quantity of food filling the container. This means a test report for a lid tested in isolation does not necessarily demonstrate compliance for the same lid used on a different container with a different fill volume.

Decoration. If the decoration sits near the rim or on the lip-contact area, migration testing must account for that contact. A test on an unprinted clear glass body does not represent the same product with a printed or enamelled decoration near the rim. The report should confirm that the decoration was included in the tested configuration.

What to request for composite products. For each food-contact component — glass body, lid, gasket, decoration — ask for the specific test evidence that covers that component under the intended use conditions. If the supplier provides a single report for the “glass jar,” ask whether the lid and gasket were tested as part of the same article, and whether the decoration was included. If the report describes only the glass body, it does not cover the complete product.

Step 5 — Separate Food Safety from Performance, Packaging, and Social Compliance

Compliance files often blend different requirements into a single document request. Keeping them separate helps buyers identify what each document actually proves.

Food-contact safety addresses whether the product transfers harmful substances to food. This is the domain of migration testing, GRAS status for glass, and the FDA CPGs.

Product performance addresses whether the product functions as intended — thermal shock resistance, impact resistance, lid seal performance, and dimensional accuracy. Performance testing is governed by product standards and buyer specifications, not by food-contact regulation.

Packaging requirements address whether the packaging protects the product during transport and meets any applicable packaging waste or labelling rules. Packaging compliance is separate from food-contact compliance and should be documented separately.

Labelling obligations vary by market. EU rules require that food-contact materials or articles be labelled with the “glass and fork” symbol or the words “for food contact,” or bear the statement “not suitable for food contact” if applicable. US labelling requirements focus on Proposition 65 warnings for California and any relevant FDA labelling provisions.

Social compliance audits such as BSCI or SMETA address labour conditions and social management systems. They do not test product safety. A BSCI report does not substitute for a migration test report, and a migration test report does not demonstrate social compliance.

Step 6 — Verify That the Document Matches the Product

A test report issued for one configuration does not automatically apply to another. The verification steps are the same for both markets.

Check the sample description. Does the report identify the exact capacity, material, colour, decoration, lid type, and gasket material of the product you are importing? A report that describes a clear glass jar with a metal lid does not cover a coloured jar with a bamboo lid and silicone seal.

Check the test method and conditions. Does the report state the standard used and the test conditions — simulant, temperature, duration? For EU-market products, ISO 7086-1 is the standard test method for lead and cadmium release from glass hollowware. For US-market decorated drinkware, ASTM C927 is the lip-and-rim test method. A report that does not name the method and conditions cannot be assessed against the applicable requirement.

Check the reported values. Does the report show measured migration results against the applicable limit, or only a pass/fail conclusion? Measured values allow you to assess margin of safety and compare against the limit of the destination market.

Check the report date and configuration changes. If the supplier has changed the glass source, the decoration process, the lid supplier, or the gasket material since the report was issued, the report may no longer represent current production. Ask the supplier to confirm whether the tested configuration still applies.

Step 7 — Build a Market-Specific Confirmation Checklist

The following checklist is organised by market and product type. It is designed to be completed with the supplier and the testing laboratory, not about them.

EU market

• Product classification: food-contact or non-food-contact? Which surfaces contact food?

• Declaration of Compliance available for the applicable framework regulation?

• GMP documentation from the factory covering the food-contact production process?

• Migration test report under ISO 7086-1 or equivalent national method?

• If decorated: does the report cover the decoration, including lip-and-rim area where applicable?

• If lid or gasket: was the complete article tested, or is a separate report required for the closure material?

• If selling into a member state with specific national measures: does the product meet that member state’s limits?

US market

• Product classification: does the product contain any non-glass food-contact material?

• For plain glass: is the glass GRAS, and are all food-contact components covered?

• For decorated glassware: ASTM C927 lip-and-rim test report?

• For lids, gaskets, and closures: migration test evidence for each food-contact material?

• If selling into California: Proposition 65 assessment completed?

Composite products (both markets)

• Separate test evidence for glass body, lid, gasket, and decoration?

• Does the lid report reflect testing on the intended container at the intended fill volume?

• Does the decoration report include the lip-contact area if applicable?

• Does the report describe the exact product configuration being ordered?

What KINGSTAR GLASSWARE Provides

At KINGSTAR GLASSWARE, compliance documentation is organised by product configuration and market, not by a generic certificate file. For EU-market orders, we provide test reports covering migration testing under ISO 7086-1 for glass food-contact products, with separate records for glass bodies, lids, gaskets, and decorations where those components contact food. For US-market orders, we provide test evidence covering the applicable FDA Compliance Policy Guide limits, including lip-and-rim testing under ASTM C927 for decorated drinkware where applicable.

We hold test reports from accredited laboratories that identify the tested configuration — capacity, material, lid type, gasket material, and decoration — so that buyers can verify that the report matches their order specification. When a product configuration changes, the compliance file is reviewed to confirm whether the existing report still applies or whether retesting is required.

We welcome buyer review of our test documentation and can provide the full reports, not just certificate summaries. If your target market requires a test or documentation we have not yet discussed, tell us the product and the destination market. We will confirm what we can provide and what may need to be arranged separately.

Ready to review the market-specific compliance file for your next order? Reach out to KINGSTAR GLASSWARE. Tell us your product, your target market, and the components that contact food. We will show you exactly what documentation we hold for that configuration — and what still needs to be tested.

FAQ

Can I use the same test report for both EU and US markets?

No. The EU and US frameworks differ in their testing standards, limits, and the way they define compliance. An ISO 7086-1 migration test report demonstrates compliance with the EU method and limits, but it does not automatically satisfy FDA requirements, which reference different test methods and limits under the Compliance Policy Guides. Conversely, an FDA CPG test report does not automatically satisfy the EU framework or national measures. Products sold in both markets typically require separate evidence aligned to each framework.

Does FDA “approval” apply to glassware?

The FDA does not “approve” glassware in the way it approves drugs or food additives. Glass is classified as Generally Recognized as Safe (GRAS) for food contact based on its long history of safe use. For plain, undecorated glass, this means no pre-market approval is required. However, GRAS status does not cover decorations, lids, gaskets, or other non-glass components. Those materials require their own food-contact assessment under the applicable FDA provisions.

Why does my glass jar need a separate test for the lid?

A glass jar with a metal, bamboo, or plastic lid is a multi-material article. The lid contacts food — directly or through condensation — and is therefore a food-contact surface. EU rules specify that caps, lids, and gaskets should be tested by applying them to the intended container under foreseeable use conditions. A test report for the glass body alone does not demonstrate compliance for the lid material or for the assembled product. Each food-contact component requires its own test evidence, or a report that covers the complete article as tested.
