HS code · 6-digit subheading
HS Code 7305.19 – Iron or steel (excluding cast iron); line pipe of a kind used for oil or gas pipelines (not seamless), (not longitudinally welded), having circular cross-sections, external diameter exceeds 406.4mm
HS code 7305.19 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), (not longitudinally welded), having circular cross-sections, external diameter exceeds 406.4mm. It is used for SSAW oil transmission pipe, HSAW natural gas pipeline, spiral welded water pipe, spiral welded slurry pipe and large diameter spiral structural pipe.
What HS 7305.19 covers
This HS code pertains to large-diameter, non-seamless iron or steel line pipes for oil or gas pipelines that are not longitudinally welded, typically implying spiral submerged arc welded (SSAW or HSAW) pipes. These pipes are essential for constructing critical energy infrastructure, particularly where very large diameters or specific project flexibility are required. Importers are generally countries undertaking large-scale energy projects, such as those in the Middle East, Russia, China, and parts of Africa, which require robust and high-capacity pipelines. Exporters are often specialized manufacturers in countries like China, Japan, and European nations known for their heavy industry and advanced welding technologies. Trade in these pipes is highly specialized, driven by specific project requirements, adherence to international standards like API 5L, and significant logistical challenges due to their size and weight. Global energy policies and infrastructure investment trends heavily influence this market.

Codes often confused with 7305.19
Common mistake. This code is distinct from 730511 (LSAW) and 730512 (other longitudinally welded pipes) because it covers non-longitudinally welded large pipes, primarily spiral welded. Misclassification can occur if the specific welding orientation is overlooked.
Top exporters and importers of HS code 730519, 2025
In 2025, the largest exporter of HS code 730519 in UN Comtrade data was China, with 33% of world exports; the largest importer in UN Comtrade data was Italy, with 61% 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 that did not report are estimated from what other countries recorded trading with them. 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).

What are common misclassifications for HS code 730519?
This code is distinct from 730511 (LSAW) and 730512 (other longitudinally welded pipes) because it covers non-longitudinally welded large pipes, primarily spiral welded. Misclassification can occur if the specific welding orientation is overlooked.
Which countries are the top exporters of goods under HS code 730519?
In 2025, the top exporters of HS code 730519 in UN Comtrade data were China ($94M, 33% of world exports), Germany ($82M) and India ($43M). World exports came to about $286M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
