Import Tips & Compliance
• Label products with maximum RPM ratings to meet safety standards and prevent misclassification as lower-duty parts
• Provide mill test reports certifying silicon carbide purity to avoid disputes over ceramic vs. agglomerated status
• Beware of anti-dumping duties on certain Asian-origin silicon carbide abrasives; check USTR lists
