Compliance is non-negotiable for road safety. For the U.S. market, tires must have the DOT (Department of Transportation) certification. For the European market, ECE (Economic Commission for Europe) certification and E-mark labeling are required, alongside EU Tire Labeling for fuel efficiency, wet grip, and external noise. Other regional standards include CCC for China, GCC for the Middle East, and INMETRO for Brazil. Always request valid certification copies from the supplier before finalizing the contract.
