HS code · 6-digit subheading
HS Code 7305.11 – Iron or steel (excluding cast iron); line pipe of a kind used for oil or gas pipelines (not seamless), longitudinally submerged arc welded, having circular cross-sections, external diameter exceeds 406.4mm
HS code 7305.11 is the 6-digit subheading for iron or steel (excluding cast iron), line pipe of a kind used for oil or gas pipelines (not seamless), longitudinally submerged arc welded, having circular cross-sections, external diameter exceeds 406.4mm. It is used for LSAW oil transmission pipe, LSAW natural gas pipeline, large diameter LSAW water pipe, LSAW slurry pipeline and LSAW structural pipe.
What HS 7305.11 covers
This HS code encompasses large-diameter, non-seamless iron or steel line pipes, specifically those manufactured using the longitudinally submerged arc welded (LSAW) method, and primarily intended for oil or gas pipelines. These pipes are crucial components in major energy infrastructure projects globally, facilitating the long-distance transport of crude oil, refined petroleum products, and natural gas. Key importers are often countries with expanding energy demands or significant hydrocarbon reserves requiring new pipeline networks, such as China, India, the United States, and nations in the Middle East and Africa. Exporters include major steel-producing nations like China, Japan, South Korea, and European countries with advanced manufacturing capabilities. Trade in these goods is highly project-driven, involving stringent quality control, adherence to international standards like API 5L, and often large-scale logistics. The market is influenced by global energy prices, geopolitical stability, and environmental regulations impacting fossil fuel infrastructure development.

Codes often confused with 7305.11
Common mistake. This code is often confused with 730512 (longitudinally welded, but not SAW) or 730519 (other non-longitudinally welded large pipes) due to the subtle differences in welding methods. It's also distinct from seamless pipes under Chapter 73.
Top exporters and importers of HS code 730511, 2025
In 2025, the largest exporter of HS code 730511 in UN Comtrade data was Germany, with 24% of world exports; the largest importer in UN Comtrade data was the United Arab Emirates, with about 18% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
