Last updated: September 2026 dataNon-stainless welded line pipe for oil and gas transmission — covering both iron/non-alloy and other alloy steel grades — is one of the most commercially significant steel pipe categories in US energy infrastructure procurement. Section 232 tariffs apply across this heading, and the alloy-steel lines (7306195000 series) may also intersect with antidumping orders depending on origin. South Korea and Turkey are the leading suppliers, with the United Kingdom, Mexico, and Germany rounding out the top sources. The heading's diameter breakpoint at 114.3 mm mirrors the structure of the stainless counterpart under 730611.

Line pipe headings (730611, 730619) are specifically for pipe used in oil or gas pipeline systems, typically manufactured to API 5L or equivalent specifications. General-purpose welded pipe of similar dimensions would fall under 730630 or 730640. The intended end-use and the applicable manufacturing specification — documented on the mill test report and commercial invoice — are the primary classification determinants.
The split follows Chapter 72 definitions: non-alloy steel lines (7306191000 series) cover iron and carbon steel pipe, while the alloy-steel lines (7306195000 series) cover pipe made from steel with alloying elements meeting the Chapter 72 threshold concentrations. The mill test report's chemical composition data is the authoritative document for making this determination at the time of entry.
