How to Verify LFGB and FDA Compliance for Stainless Steel Drinkware

When sourcing stainless steel tumblers and vacuum flasks from China, food-contact compliance is non-negotiable for EU and US buyers. Two standards appear most often in vendor questionnaires: LFGB (Germany / EU framework) and FDA (United States). This guide explains what to verify, which documents to request, and how to spot incomplete certification claims.

What LFGB and FDA Actually Cover

LFGB sets migration limits for substances that may transfer from materials into food. For stainless steel drinkware, labs test lead, cadmium, and overall migration under specific conditions.

FDA compliance for food-contact materials references CFR 21 requirements. US buyers typically expect documentation showing steel components meet food-contact provisions — often supported by third-party lab reports.

Key fact for buyers: Compliance is per material and per test report, tied to specific product construction (liner, gasket, paint, ink).

Documents to Request from Your Supplier

1. Third-party lab test report — dated within the last 12–24 months
2. Sample description — must match your SKU
3. Material declaration — 304 vs 316 steel, silicone grade, ink system
4. Sub-supplier breakdown — if lids or seals come from another factory

At Jinhua Sonin Hardware, LFGB and FDA reports are shared during qualified vendor review.

Red Flags

• Generic report with no product photo or SKU reference
• "Food grade stainless steel" without migration test data
• Decoration ink excluded from the tested sample
• Certificate predates a mold change or lid redesign

LFGB and FDA verification is a document discipline, not a handshake claim. Need reports for a specific tumbler line? Contact our export team.
