Compliance varies by region, but for the US market, you must ensure products meet CPSC (Consumer Product Safety Commission) requirements, particularly regarding lead content in buttons/zippers and flammability standards (16 CFR Part 1610). For the EU, products should adhere to REACH regulations for chemical safety. If you are sourcing children's crochet wear, pay extra attention to small parts (choking hazards) and ensure the supplier provides OEKO-TEX® Standard 100 certification to guarantee the absence of harmful substances.
