U.S. imports of seamless stainless steel line pipe for oil & gas pipelines (HS 730411) totaled $4.4M in August 2026, imported from 23 countries.
Importers of Seamless Stainless Steel Line Pipe for Oil & Gas Pipelines paid $1.9M in duties in August 2026, an effective tariff rate of 42.09% of the $4.4M imported — duty actually collected as a share of that value, not the published tariff schedule.
Last updated: August 2026 dataStainless steel grade selection drives both the classification and the commercial value of seamless line pipe used in corrosive or high-temperature oil and gas service — austenitic, duplex, and super-duplex grades each command different price points and are specified by API 5LC or equivalent standards. The US schedule breaks this heading into three outer-diameter bands: up to 114.3 mm (7304110020), 114.3–406.4 mm (7304110050), and above 406.4 mm (7304110080), with a legacy consolidated line at 7304110000. These products are subject to Section 232 tariffs on steel, and certain country-of-origin combinations may also trigger antidumping or countervailing duty orders applicable to steel pipe and tube — importers should conduct a scope ruling check before entry.

The three OD bands — ≤114.3 mm, 114.3–406.4 mm, and >406.4 mm — correspond to separate 10-digit HTS lines (7304110020, 7304110050, and 7304110080 respectively). While the base MFN duty rate may be the same across bands, antidumping or countervailing duty orders on steel pipe can be scope-limited by diameter, so the correct OD classification directly determines whether a trade-remedy order applies.
A mill test certificate (MTC) conforming to EN 10204 3.1 or equivalent, showing the chemical composition and confirming the stainless steel designation, is the standard supporting document. CBP may request this to verify that the pipe is not misclassified as carbon or alloy steel, which would fall under different HTS lines and potentially different trade-remedy orders.
