Chapter 72Iron and steel

The headings in this chapter of Canada's Customs Tariff. Each one opens on the numbers it contains.

Chapter 72 covers the material: pig iron, ferro-alloys, flat and long products, up to semi-finished forms. There it stops. Anything that is a recognisable article belongs to Chapter 73.

This chapter is governed by its notes more than by its wording. Note 1 defines in law what alloy steel, stainless steel and a flat-rolled product are: these are numeric composition thresholds, and an analysis that crosses one changes the heading, whatever the product is called commercially.
