Import Tips
• Verify seal material composition (e.g
• carbon, ceramic faces) for accurate HTS classification and ensure supplier provides certification
• Include detailed technical specs like pressure rating and shaft size in import documentation to avoid misclassification as parts
• Check for anti-dumping duties on seals from certain origins and maintain proof of end-use in machinery
