U.S. imports of stainless steel flanges (SITC 67953) totaled $24.3M in July 2026, traded with 44 countries.

Importers of Stainless Steel Flanges paid $13.5M in duties in July 2026 — an effective duty rate of 56% on $24.0M in dutiable value, based on actual customs collections rather than the published tariff schedule. Stainless Steel Flanges imports of $24.3M in July 2026 ran 18% above the year-to-date monthly average of $20.6M.

Last updated: July 2026 data

Stainless steel flanges serve as the primary bolted connection point in corrosion-resistant piping systems across chemical processing, pharmaceutical, food and beverage, and offshore energy applications. Grades such as 304, 316, and duplex stainless are commercially significant distinctions that affect both pricing and applicable ASTM/ASME standards. Imports of stainless steel flanges have been subject to antidumping and countervailing duty orders from multiple origins, and Section 232 tariffs on steel also apply, making landed-cost modeling essential before sourcing decisions.

Frequently Asked Questions

Which stainless steel grades are most commonly traded under this heading, and does grade affect duty exposure?

Grades 304 and 316 (and their low-carbon 'L' variants) dominate commercial trade, with duplex grades like 2205 used in more demanding corrosive environments. While the SITC heading does not subdivide by grade, the HTS schedule does, and antidumping scope rulings have sometimes turned on alloy composition — so importers should confirm that the specific grade and chemistry of their flanges fall within or outside any active order's scope.

What certifications do buyers typically require for imported stainless steel flanges?

Most industrial buyers require material test reports (MTRs) certified to ASTM A182 or equivalent standards, along with dimensional compliance with ASME B16.5 or B16.47 for pressure-class flanges. For pharmaceutical and food-grade applications, surface finish certifications and traceability to heat numbers are also standard requirements.
