Import Tips
• Provide ASTM A213 certification and heat treatment records to confirm the T9 grade
• Ensure the outside diameter is declared accurately, as sizes under 38.1 mm may have specific statistical codes
• Consult the CBSA for duty rates, and consider applying for a ruling if the end-use is ambiguous
