Compliance is critical to avoid customs seizures. For the EU market, products must adhere to REACH regulations, ensuring the absence of harmful substances like lead, cadmium, and phthalates. For the US market, compliance with California Proposition 65 regarding chemical content is essential. If the bags include electronic components (like USB charging ports), they must carry CE, FCC, or RoHS certifications. Additionally, look for suppliers with BSCI (Business Social Compliance Initiative) or ISO 9001 to ensure ethical production and quality management.
