Import Tips & Compliance
• Maintain a certificate of analysis from the supplier showing the exact niobium, phosphorus, sulfur, and silicon percentages for customs clearance
• Confirm the product is in a primary form (e.g
• lumps, blocks) as defined in Chapter Note 1(c) of Chapter 72
• If the product is blended with other ferro-alloys, seek a ruling from the CBSA to determine the correct classification
