Summary: GB 4806.16-2025 (effective Sep 2026) phases out precipitated silica in HTV, driving 10,000-ton fumed silica demand surge and 30% cost increase. Detailed Content: China’s first independent national standard for food contact silicone rubber, GB 4806.16-2025, will take effect on September 2, 2026, after a one-year transition period. The standard imposes stricter restrictions on volatile organic compounds (VOCs), heavy metal residues, and food migration indices, significantly raising industry access thresholds. Notably, it phases out precipitated silica in high-temperature vulcanized (HTV) silicone, mandating fumed silica for food-grade applications. This shift triggers an additional 10,000-ton annual demand for fumed silica, driving a 30% increase in raw material costs for food-grade silicone producers. Hongye Silicone proactively advances formula adjustments, production environment renovations, and comprehensive product testing. All finished products—including baking mold silicone, baby nipple silicone, and food container sealing silicone—fully comply with GB 4806.16, FDA, and EU food safety standards, ensuring uninterrupted sales in global food contact markets.
