New National Food-Grade Silicone Standard GB 4806.16-2025 to Take Effect in September, Upgrading Liquid Silicone Production Threshold

Keywords: food contact liquid silicone, GB 4806.16-2025, food-grade LSR testing, low volatile silicone, domestic silicone export compliance Key Sentence: China’s brand-new national safety standard for food silicone rubber will be fully implemented on September 2, tightening limits on volatile substances and heavy metal precipitation for all food-grade liquid silicone materials. On July 23, 2026, material testing institutions issued early warning notices to liquid silicone manufacturers focusing on kitchenware, baby products and baking molds. The updated GB 4806.16-2025 standard raises stricter detection indicators for food-contact LSR, capping total volatile organics at 0.5% and adding mandatory potassium permanganate consumption testing items that were absent in the old version. Manufacturers must upgrade production formulas and launch full batch third-party testing before September to obtain new compliance reports. Small factories without complete testing equipment face production suspension risks, while certified large liquid silicone plants seize extra overseas orders from MERCOSUR and Southeast Asia, whose local food silicone rules align closely with the new Chinese standard. Industry analysts predict low-odor, low-migration food-grade liquid silicone will occupy over 80% of export shipments by Q4, and factories that complete early compliance transformation will enjoy obvious competitive advantages in global food silicone markets.
