Last updated: August 2026 dataNarrow, heavy-gauge hot-rolled stainless strip or bar-in-coil — under 600 mm wide but at least 4.75 mm thick — is a specialized input for machined components, flanges, and wear-resistant parts where the combination of stainless corrosion resistance and substantial cross-section is required. The sub-600 mm width places this product in the narrow flat-rolled category, which is classified separately from wide plate and carries its own tariff line under Section 232 coverage. Width measurement methodology (including edge condition) can affect whether a product falls above or below the 600 mm threshold.

CBP measures width at the widest point of the product as presented. Edge condition matters: products with mill edges versus slit edges may measure differently. If a product is borderline, importers should obtain a certified width measurement from the mill and be prepared for physical verification at the port.
Flanges, valve bodies, pump components, and structural brackets in chemical processing and marine environments are common end uses. The heavy gauge provides the stock thickness needed for machining, while the stainless composition resists corrosive service conditions.
