GB 4806.16-2025 Food-Contact Silicone Standard – 5-Month Co
Keywords: Food-contact silicone, GB 4806.16-2025, compliance, D4~D7, volatile matter, peroxide value
Core Summary: With only 5 months left before the mandatory implementation of China’s National Food Safety Standard for Silicone Materials and Products in Contact with Food (GB 4806.16-2025) on September 2, 2026, domestic food-contact silicone enterprises are accelerating product formula upgrades and compliance testing.
-
Key Requirements: Sets 9 exclusive limit indicators, including total specific migration of dimethylcyclosiloxanes (D4~D7) ≤10 mg/kg, volatile matter ≤0.5%, peroxide value ≤5 mmol/kg.
-
Testing Method: Introduces the “polar food simulant 95% ethanol + n-heptane dual system” detection method, solving the evaluation blind spot of silicone in high-oil contact scenarios.
-
Industry Response: Leading enterprises have reduced D4~D7 migration from 18 mg/kg to 4 mg/kg by adopting low-cyclic gum and platinum vulcanization formulas. Market supervision will conduct special inspections in Q4 2026, increasing random inspection ratio from 2% to 6%.
