FDA vs LFGB Silicone: What Buyers Actually Need for US and EU Markets

If you sell silicone kitchenware or baby products into both the US and EU, you already know the labels: FDA 21 CFR 177.2600 and German LFGB. What many buyers miss is that LFGB is, for most parameters, the stricter of the two — and designing for LFGB gets you a product that passes both.

The core difference

FDA 21 CFR 177.2600 specifies permitted base polymers and sets extractables limits using prescribed solvents. LFGB (via BfR XV) adds total volatile organic matter limits, stricter migration testing in actual food simulants, and — critically — sensory testing: the product must not transfer odor or taste. A mat can pass FDA and still fail LFGB on smell alone.

• Selling only to the US: FDA-compliant platinum-cured silicone is sufficient
• Selling to the EU: insist on LFGB/BfR XV certification with recent (≤2 years) test reports
• Selling to both: specify LFGB-grade material — it covers FDA in practice, but keep both certificates on file

The volatility number that matters

Ask any supplier for one number: total volatile matter at 200°C. Commodity grades run 0.5–1.0%; proper LFGB grades run below 0.5%, and our baby-care compounds run below 0.3%. High volatility is what causes the "silicone smell" in cheap products and is the single best predictor of post-cure odor complaints — the exact scenario in our baking-mat case study.
