Importers of Iron & Non-Stainless Steel Pipe Fittings (Other) paid $16.4M in duties in July 2026 — an effective duty rate of 53% on $31.2M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataSocket-weld fittings, unions, nipples, and other pipe and tube fittings of iron and non-stainless steel that do not fall under flanges, threaded, or butt-welding categories are captured here — a residual heading that covers a wide range of industrial and commercial piping components. China is the dominant supplier, with Israel, Germany, India, and Vietnam also contributing meaningfully to US import volumes. Chinese-origin goods under this heading are subject to both Section 232 steel tariffs and Section 301 tariffs, making total landed-cost calculations particularly important for sourcing decisions. The seven 10-digit lines distinguish by alloy composition, machining/processing status, and whether the article is a nipple or another fitting type.

Yes. The US schedule includes a dedicated 10-digit line for nipples of iron/nonalloy steel that have been machined, tooled, or processed (7307995015), distinct from the broader residual line for other machined fittings (7307995045). Correct identification of the article type is necessary to avoid misclassification.
China leads supply under this heading, but Section 301 tariffs add a significant cost layer on top of the base duty and Section 232 tariffs. Many importers have responded by qualifying alternative suppliers in India or Vietnam, though they must ensure those suppliers' goods genuinely originate in the declared country to avoid transshipment scrutiny.
