Silicone is used across wildly different product categories — kitchenware, baby products, industrial seals, phone accessories — and the grade of silicone used matters enormously depending on whether the product will contact food or skin.
Food-Grade vs Industrial-Grade Silicone
Food-grade silicone is manufactured to be free of fillers and additives that could leach into food, and is tested against FDA 21 CFR 177.2600 (US) or LFGB (Germany/EU) standards. Industrial-grade silicone is cheaper but may contain fillers or coloring agents not suitable for food or extended skin contact — using it in kitchenware or baby products is both a safety and compliance risk.
Key Tests to Request
For food-contact silicone products, request migration testing (checking what, if anything, transfers from the silicone into food simulants) alongside the base material certification. LFGB testing in particular is considered a rigorous benchmark and widely accepted as evidence of food-safety even outside Germany.
Common Silicone Product Categories and Considerations
Baking mats and molds need high heat resistance (typically rated to 220-240°C) alongside food-grade certification. Baby products (teethers, bibs) need food-grade silicone plus additional scrutiny for phthalate-free and BPA-free claims. Industrial gaskets and seals prioritize durometer (hardness) specification and chemical resistance over food safety.
Frequently Asked Questions
How can I tell if a silicone product is genuinely food-grade?
Request the specific certification (FDA 21 CFR or LFGB) and migration test report for your exact product, not just a general ‘food safe’ claim from the factory.
Is LFGB certification only relevant for the German market?
While it originated as a German standard, LFGB testing is widely recognized internationally as a strong food-safety benchmark and is often requested by buyers outside Germany too.
What heat resistance should food-grade silicone bakeware have?
Typically 220-240°C is standard for oven-safe silicone bakeware; confirm the specific rating for your product’s intended use since some kitchen items don’t need oven-level heat resistance.
