New GB 4806.16-2025 Standard Boosts Food-Grade LSR Factory Certification Rush One Month Before Implementation

2026,07,31
Keywords: food-grade liquid silicone, GB 4806.16-2025, food contact silicone certification, Mold Silicone for baking, low cyclic siloxane LSR
Addition curing silicone
 
Key Sentence: Domestic food-contact liquid silicone manufacturers speed up product testing and factory compliance upgrades, as China’s exclusive food silicone national standard will formally take effect on September 1, 2026.
On July 31, 2026, third-party material testing institutions in Guangdong reported a sharp surge in food-grade liquid silicone testing orders. The newly released GB 4806.16-2025 standard raises strict limits on volatile siloxane, heavy metal migration and extractable substances for baking molds, chocolate casting silicone and kitchen silicone tools, eliminating unqualified low-end general silicone from the food contact market.
Silicone manufacturers in Shenzhen and Huizhou add dedicated purification production lines to reduce D4/D5 cyclic siloxane residue below 0.1%. Factories that complete full certification can export food-grade LSR to EU and North America without extra REACH supplementary tests. Industry analysts predict uncertified small workshops will withdraw from the market within two months, and certified premium food liquid silicone will see a 15% price premium amid tight qualified supply.
Cross-border e-commerce and overseas baking brand buyers have started prioritizing suppliers with full GB food certification, and long-term bulk orders for food mold silicone have increased significantly this month.
