Import Tips
• Document the oxygen content and copper purity with a mill certificate to support the refined copper classification
• Since OFHC billets are often used in specialized applications, ensure the end-use does not affect tariff classification
• Check for any applicable anti-dumping or countervailing duties on copper products
