Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If forged rather than rolled
Forged flat-rolled products use Chapter 72 forged headings.
If other high-strength specs not fitting thickness
High-strength steel outside 3-4.75 mm uses general 7208.90 other category.
If made into gas turbine casings
Fabricated into machinery parts shifts to Chapter 84 specific equipment.
