For international trade, machinery must adhere to rigorous safety standards. Ensure products carry CE marking (Europe), ANSI/ALC certification (USA), or ISO 9001:2015 for quality management systems. Key technical specs to monitor include lifting height/speed, torque accuracy for pneumatic tools, and software update frequency for electronic diagnostic scanners. For heavy-duty equipment like wheel aligners or engine hoists, look for powder-coated finishes to prevent corrosion and fail-safe locking mechanisms to ensure operator safety.
