Last updated: August 2026 dataWelded stainless steel line pipe for oil and gas service occupies a premium niche within the OCTG and pipeline market, selected for its corrosion resistance in sour-service, offshore, and chemical-injection applications where carbon steel would degrade. The US schedule divides this heading by diameter at the 114.3 mm threshold: 7306110010 covers smaller-diameter pipe and 7306110050 covers larger-diameter pipe, with 7306110000 as the residual line. Turkey and Italy are the leading suppliers to the US under this heading, with the Netherlands, China, and France also among the top sources.

API 5LC (Line Pipe for Use with Corrosive Fluids) and ASTM A312 are frequently cited for stainless steel line pipe in oil and gas service. While HTS classification does not depend on the specification itself, these standards appear on mill test reports and commercial invoices and help customs officers and brokers confirm the product's intended end-use as line pipe rather than a general-purpose tube.
The 114.3 mm (approximately 4.5-inch nominal) outside diameter threshold splits the heading into two distinct 10-digit tariff lines — 7306110010 for pipe below that diameter and 7306110050 for pipe at or above it. Both lines are subject to Section 232 tariffs on steel, but the diameter split can also be relevant if any antidumping or countervailing duty orders are scoped by size range, making accurate diameter documentation essential.
