Import Tips
• Document the phosphorus content clearly, as the 15% threshold is critical for classification under this tariff item
• If the product is imported in master alloy form for foundry use, confirm whether it meets the definition of a phosphide versus a copper alloy
• Consider requesting a CBSA advance ruling to avoid reclassification at the border
