The T-bend rating measures how tightly a prepainted steel strip can be bent without the coating cracking or losing adhesion — a 0T bend means the strip can be folded flat on itself. For roll-formed or stamped narrow-strip applications, specifying the minimum acceptable T-bend rating on the purchase order ensures the coating system is compatible with the forming process and prevents field failures.

Yes. Section 232 tariffs apply to flat-rolled steel products broadly, without a width-based exemption. Both wide (67431) and narrow (67432) prepainted steel are covered. Importers seeking a product-specific exclusion must apply separately for each applicable HTS 10-digit subheading, as exclusions are not automatically transferable across width categories.
