Product classification
HS code for Steel pipeline: 7306.19
Iron or steel (excluding cast iron), line pipe of a kind used for oil or gas pipelines (other than of stainless steel or seamless), n.e.c. in chapter 73.
Classification of steel pipeline under HS 7306.19
The classification of steel pipelines under HS code 730619 is based on the manufacturing method and the intended application. Heading 7306 covers tubes, pipes, and hollow profiles of iron or steel that are welded or otherwise joined (as opposed to seamless). Within this heading, the 7306.1 series is dedicated to line pipe of a kind used for oil or gas pipelines. Subheading 730619 specifically refers to these pipes when they are made of iron or steel other than stainless steel and are not covered by more specific subheadings like 730611 (longitudinally submerged arc welded). This code is critical for the energy sector, covering the transport infrastructure for hydrocarbons. The classification depends on the pipe being "welded" and having an external diameter that does not exceed 406.4 mm (as pipes larger than this fall under heading 7305).
- Covers
- Welded line pipe for oil and gas transport
- Electric Resistance Welded (ERW) steel pipes
- Spiral welded pipes for pipelines (under 406.4mm)
- Carbon steel line pipe
- Hollow profiles for pipeline use
- Also under 7306.19
- API 5L X65 line pipe from Tenaris
- EVRAZ large-diameter line pipe
- JFE Steel oil and gas pipelines
- Sumitomo Metal line pipe
- ArcelorMittal energy pipelines
Codes often confused with 7306.19
Common mistake. Steel pipelines are frequently misclassified under 730419, which is the code for seamless line pipe. The distinction between seamless (7304) and welded (7306) is a fundamental divide in the HS system. Another common error involves heading 7305, which is for pipes with an external diameter exceeding 406.4 mm. If the pipe is intended for structural use rather than oil/gas transport, it should be classified under 730630 or 730661. Finally, stainless steel line pipe must be classified under 730611.
Top exporters and importers of HS 730619 (the code used for steel pipeline), 2025
In 2025, the largest exporter of HS 730619 (the code used for steel pipeline) in UN Comtrade data was South Korea, with 22% of world exports; the largest importer in UN Comtrade data was the United States, with 31% 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).
