Ensure all products comply with REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) standards for the EU market, specifically testing for hexavalent chromium, lead, and phthalates in leather and adhesives. For the US market, verify compliance with ASTM standards for slip resistance. It is highly recommended to source from suppliers with ISO 9001 (Quality Management) and BSCI (Business Social Compliance Initiative) certifications to ensure ethical production and consistent quality.
