HS code · 6-digit subheading
HS Code 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
HS code 7306.19 is the 6-digit subheading for 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. It is used for carbon steel natural gas pipelines, crude oil transmission lines, refined product pipelines, offshore oil flowlines and onshore gas gathering lines.
What HS 7306.19 covers
This code encompasses welded iron or steel line pipe (excluding stainless steel and seamless types) specifically designed for oil or gas pipelines, not elsewhere specified in Chapter 73. These are the workhorses of the global energy transportation network, forming the vast majority of onshore and offshore pipelines for crude oil, natural gas, and refined petroleum products. Countries with extensive oil and gas reserves, production, and consumption, such as the USA, Russia, Canada, China, and Middle Eastern nations, are the primary importers and exporters. The trade volume is immense, driven by global energy demand, new field developments, and pipeline infrastructure expansion and maintenance. Buyers are typically large energy companies, national oil companies, and specialized pipeline construction contractors. Key things to know include the various grades of steel used (e.g., API 5L standards), which dictate strength and suitability for different pressures and environments, and the distinction from stainless steel or seamless pipes.

Codes often confused with 7306.19
Common mistake. This code is frequently confused with 730419 (seamless non-stainless line pipe) due to identical end-use, but the crucial distinction is the manufacturing method (welded vs. seamless). It's also distinct from 730630 which covers general welded pipes not specifically for oil/gas.
Top exporters and importers of HS code 730619, 2025
In 2025, the largest exporter of HS code 730619 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).
