Import Tips
• Include ASTM B280 certification specifying phosphorized refined copper to distinguish from alloys
• Document intended welding end-use but classify based on form, not application, to avoid 83xx tool steel confusion
• Check for anti-dumping duties if sourced from certain Asian producers; verify Commerce scope rulings
