Import Tips & Compliance
• Verify the plate's width is at least 600 mm and that it is in the form of a flat-rolled product, not further worked than rolled
• Keep documentation showing the alloy composition, especially molybdenum and nickel percentages, to support classification
• Consult the CBSA's tariff classification advice if the product has been cut to non-rectangular shapes, as this may affect the tariff item
