NHC and SAMR published GB 4806.10-2025 (coatings/coating layers for food-contact materials and articles) and GB 4806.16-2025 (silicone rubber materials and articles for food contact). Both product standards take effect on 2 September 2026.
What changed
- Coatings: broader scope (including certain paper coatings and indirect-contact layers), clearer base-raw-material controls, refined physicochemical and specific migration expectations.
- Silicone rubber: standalone standard with defined indicators (overall migration, potassium permanganate consumption, heavy metals, volatiles, specific migration) and migration testing aligned with GB 31604.1 principles.
Actions for manufacturers
- Map SKUs that fall under the new scopes.
- Verify base materials and additives against allowed lists / GB 9685.
- Schedule migration and key physicochemical testing under realistic use conditions.
- Align labeling and supplier declarations before the effective date.
