To avoid customs seizures and legal liabilities, ensure products meet regional safety standards. For the US market, toys should comply with ASTM F963 (Standard Consumer Safety Specification for Toy Safety). For the EU, look for the CE Mark and compliance with EN71 (Parts 1, 2, and 3), which covers mechanical properties, flammability, and chemical migration. Additionally, check for REACH compliance regarding hazardous substances. If sourcing from Made-in-China.com, look for Audited Suppliers who provide downloadable lab test reports.
