U.S. imports of iron & non-stainless steel butt welding fittings (HS 730793) totaled $25.8M in April 2026, traded with 27 countries.
Importers of Iron & Non-Stainless Steel Butt Welding Fittings paid $12.9M in duties in April 2026 — an effective duty rate of 53% on $24.5M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataButt welding fittings — including elbows, reducers, tees, and caps — are permanently welded into high-pressure piping systems used in oil-and-gas, power generation, and chemical processing, making material certification and dimensional standards critical at entry. Italy and South Korea lead US imports under this heading, with Malaysia, Canada, and Vietnam also significant sources. The eight 10-digit lines segment by alloy type (iron/nonalloy vs. non-stainless alloy steel), machining status, and inside-diameter threshold (below or at/above 360 mm). Section 232 tariffs apply broadly, and importers should verify whether specific antidumping or countervailing duty orders cover the alloy grade and origin combination being imported.

The US schedule separates fittings that have not been machined, tooled, or otherwise processed from those that have. An unprocessed forged blank and a finished machined fitting of the same alloy and diameter can fall under different 10-digit lines, so importers must confirm the manufacturing stage at the time of export.
End-users in pressure-service applications generally require mill test reports (MTRs) certifying compliance with ASTM A234 or equivalent standards, along with heat and lot traceability. Customs brokers may also need a manufacturer's affidavit confirming country of origin, particularly where circumvention of antidumping orders is a concern.
