U.S. imports of iron & non-stainless steel threaded elbows, bends & sleeves (HS 730792) totaled $33.1M in April 2026, traded with 44 countries.
Importers of Iron & Non-Stainless Steel Threaded Elbows, Bends & Sleeves paid $13.6M in duties in April 2026 — an effective duty rate of 44% on $31.1M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataThreaded elbows, bends, and sleeves (pipe couplings) of iron and non-stainless steel are essential connectors in plumbing, fire-protection, and industrial fluid-handling systems where disassembly is required. Colombia and Mexico are the leading US suppliers under this heading, with India and China also significant sources — a supplier mix that reflects both proximity-driven logistics and competitive manufacturing costs. All steel articles entering the US are subject to Section 232 tariffs, and Chinese-origin fittings carry additional Section 301 exposure. The three 10-digit lines distinguish between iron/nonalloy sleeves (7307923010), non-stainless alloy sleeves (7307923030), and threaded elbows and bends (7307929000).
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Sleeves are straight connectors that join two pipe ends axially, while threaded elbows and bends redirect flow at an angle. Under this heading, sleeves of iron/nonalloy steel and non-stainless alloy steel each have their own 10-digit line, whereas all threaded elbows and bends share a single residual line (7307929000).
Colombia has developed a competitive malleable-iron and carbon-steel fitting manufacturing sector and benefits from geographic proximity that reduces lead times and freight costs compared to Asian suppliers. Importers sourcing from Colombia should verify that goods meet applicable ASTM or ASME standards required by US end-users.
