Introduction

Food grade color coated aluminum is widely used in food packaging, baking trays, food containers, beverage caps and kitchenware. When exporting to the European Union and North American markets, food-contact safety compliance is mandatory. The coating layer is the key object for food contact testing, even though the substrate is aluminum. Many buyers and manufacturers confuse certification documents and test items between FDA and (EU) No 10/2011. This article sorts out the mandatory compliance documents for EU and North America, and details full test items under FDA 21 CFR and EU 10/2011 for color coated aluminum.

Mandatory Certifications & Compliance Documents for EU Market

Core Regulations

Regulation (EC) No 1935/2004: Framework regulation for all food contact materials and articles in EU, covers color coated aluminum composite structure (aluminum substrate + organic coating). It requires traceability, no harmful substance release and manufacturer Declaration of Compliance (DoC).

Regulation (EU) No 10/2011: The main standard for plastic coating layers on metal substrates, governing monomers, additives, pigments and migration limits of the organic coating.

Regulation (EU) No 2023/2006: Good Manufacturing Practice (GMP) for food contact materials.

Required Supporting Documents

1.Declaration of Compliance (DoC): Self-declaration issued by manufacturer, listing material composition, applicable simulants, migration test results and intended food contact conditions. Mandatory before placing products on EU market.

2.Third-party laboratory test report for EU 10/2011, from accredited labs such as SGS, TÜV, Intertek.

3.Raw material statements of coating: resin, pigment, curing agent and additives must be listed in EU positive substance list.

4.Optional but frequently requested: LFGB test report (Germany national food contact requirement), EN standards for aluminum substrate (EN 601 / EN 602).

Mandatory Certifications & Compliance Documents for North American Market (USA & Canada)

USA FDA Requirements

FDA does not issue product “certificates”. Suppliers provide FDA compliance documentation plus accredited lab test reports to prove the color coated aluminum meets Title 21 CFR.

• 21 CFR Part 175.300: Indirect food additives – resinous and polymeric coatings (the most widely used clause for food grade color coated aluminum).

• Related clauses: 21 CFR Part 177 for polymer materials, 21 CFR 178.3297 for food-contact colorants.

Canada Requirements

Canada Health Food Contact Material guidelines: color coated aluminum must demonstrate extractive and heavy metal test results comparable to FDA standards. Third-party food contact test reports are normally requested by importers.

Common Supplementary Certifications for Both Markets

• ISO 9001 Quality Management System

• ISO 22000 / HACCP for food safety production control

• RoHS (optional, often required by buyers for heavy metal control)

Full Test Items of EU (EU) No 10/2011 for Food Grade Color Coated Aluminum

1. Overall Migration Test

Overall migration measures total transfer of all non-volatile substances from coating into food simulants.

• Simulants:

Simulant A: 10% ethanol (aqueous, alcoholic food)

Simulant B: 3% acetic acid (acidic food like fruit juice, tomato sauce)

Simulant D2: Olive oil (fatty / oily food)

• Limit: ≤10 mg/dm² or 60 mg/kg

• Test temperature & time: selected according to real intended use (cold storage, room temp, baking / high temperature cooking)

2. Specific Migration Test (SML, Specific Migration Limit)

Test targeted restricted substances with fixed maximum limits:

• Heavy metals: Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent Chromium Cr(VI)

• Bisphenol A (BPA) and Bisphenol derivatives

• Formaldehyde

• Phthalates (DEHP, DBP, BBP etc.)

• Other monomers and additives listed in EU 10/2011 Annex

3. Material Composition & Raw Material Verification

Check whether coating resin, monomer, pigment, additive are included in EU positive list

Restricted / prohibited substance screening: PFAS, certain carcinogenic additives

4. Visual & Sensory Inspection

Odour, taste, coating defect, peeling, delamination of color coating after simulant immersion.

Note: EU 10/2011 originally targets plastic materials, but it applies to plastic organic coating layers on aluminum substrate, which is exactly the food grade color coated aluminum case. The aluminum base metal follows EC 1935/2004 and Council of Europe metal resolution.

FDA 21 CFR Test Items for Food Grade Color Coated Aluminum (Mainly 21 CFR 175.300)

1. Extractables / Migration Test under FDA Simulants

FDA uses three standard extractants based on intended food type and usage temperature:

• Distilled water (simulate aqueous food)

• 8% ethanol (alcohol-containing food)

• n-Heptane (simulate fatty, oily food)

Test temperature and duration match real application scenarios: room temperature storage, refrigeration, frozen storage, high-temperature baking / heating.

Total non-volatile extractables shall meet the limits defined in 21 CFR 175.300.

2. Heavy Metal Screening

Lead, cadmium and other heavy metal extract detection from coating under acidic extractant.

3. Coating Component Qualification Check

• Resin, curing agent, pigment, additives must be FDA approved food contact substances

• Pigments comply with 21 CFR 178.3297

• Verify coating curing condition: incomplete curing will cause excessive monomer extraction

4. Functional Performance Auxiliary Tests (Buyer Often Requests)

Coating adhesion, corrosion resistance, boiling resistance, scratch resistance (not mandatory FDA regulatory test, but widely required for packaging and baking applications).

Key Differences Between EU 10/2011 and FDA 21 CFR for Color Coated Aluminum

• Restriction focus: EU 10/2011 has clear SML for hundreds of individual substances; FDA focuses on total extractables plus positive list approval of raw materials.

• Legal form: EU requires DoC declaration + migration test; FDA relies on material listing and extract test without official certificate issuance.

• Simulant system: EU uses 10% ethanol, 3% acetic acid, olive oil; FDA uses water, 8% ethanol and n-heptane.

• Heavy metal rules: EU sets strict specific migration limits for heavy metals; FDA controls heavy metals through extractable testing.

Practical Export Tips for Food Grade Color Coated Aluminum

• Confirm end-use scenario first: cold packaging only or high-temperature baking, to select correct test temperature and simulants. Wrong test condition will invalidate reports.

• The test sample must use identical coating formula, coating thickness and curing process as mass production.

• Prepare full technical file: alloy certificate, coating raw material MSDS, test report, DoC (EU), batch traceability records.

• For dual-market shipments (EU + USA), conduct both EU10/2011 and FDA 21 CFR tests in one accredited lab to reduce cost and lead time.

Conclusion

Exporting food grade color coated aluminum to EU and North America needs region-specific compliance packages. EU requires EC1935/2004 framework, EU10/2011 coating migration tests and manufacturer DoC. North America (USA) follows FDA 21 CFR Part 175.300 extractable testing and approved raw material verification. Understanding the full test items of EU10/2011 and FDA helps manufacturers avoid customs detention, product rejection and food safety liability, and supports stable cooperation with food packaging, kitchenware and food container buyers worldwide.
