HS Code 7304.19 – Iron or steel (excluding cast iron or stainless steel); seamless, line pipe of a kind used for oil or gas pipelines
HS code 7304.19 is the 6-digit subheading for iron or steel (excluding cast iron or stainless steel), seamless, line pipe of a kind used for oil or gas pipelines. It is used for seamless carbon steel line pipe, API 5L grade B pipe, high-strength low-alloy (HSLA) seamless pipe, sour service seamless pipe and large diameter seamless pipe.
What HS 7304.19 covers
This code covers seamless line pipes made from iron or steel (excluding cast iron and stainless steel), specifically designed for oil or gas pipelines. These pipes are fundamental to the global energy sector, forming the backbone of transportation networks for crude oil, refined petroleum products, and natural gas over long distances. The "seamless" manufacturing process ensures high structural integrity and resistance to internal pressure, making them suitable for critical infrastructure. International trade is driven by the continuous development and expansion of energy infrastructure worldwide, including new pipeline projects and the replacement of aging sections. Importers are typically energy companies, national oil and gas corporations, and construction firms involved in large-scale energy projects. Exporters are major steel-producing nations with advanced manufacturing capabilities. Key factors in this trade include compliance with API 5L standards, specific steel grades (e.g., X52, X65), diameter, wall thickness, and the ability to withstand diverse environmental conditions.

Codes often confused with 7304.19
Common mistake. This code is for non-stainless, seamless line pipe for oil/gas; it differs from 730411 (stainless line pipe) and 730431 (general purpose cold-drawn seamless pipes).
Top exporters and importers of HS code 730419, 2025
In 2025, the largest exporter of HS code 730419 in UN Comtrade data was China, with 44% of world exports; the largest importer in UN Comtrade data was the United States, with 13% 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).
