HS Code 7304.11 – Iron or steel (excluding cast iron); seamless, line pipe of a kind used for oil or gas pipelines, of stainless steel
HS code 7304.11 is the 6-digit subheading for iron or steel (excluding cast iron), seamless, line pipe of a kind used for oil or gas pipelines, of stainless steel. It is used for stainless steel seamless line pipe, API 5L stainless pipe, corrosion-resistant pipeline steel, duplex stainless steel pipe and super duplex stainless steel pipe.
What HS 7304.11 covers
This highly specific HS code targets seamless line pipes made of stainless steel, designed for the demanding environment of oil and gas pipelines. The "seamless" characteristic ensures superior strength and integrity, crucial for high-pressure applications, while "stainless steel" provides exceptional corrosion resistance, vital for transporting corrosive media or operating in harsh environments. International trade in these specialized pipes is directly linked to global energy infrastructure projects, including new pipeline construction and maintenance in oil and gas fields. Major importers are typically energy companies and national oil corporations in resource-rich countries or transit nations. Exporters are specialized steel manufacturers in technologically advanced industrial economies. Key considerations include material grade (e.g., 304, 316L), pressure ratings, wall thickness, adherence to API (American Petroleum Institute) standards, and certification for critical applications where safety and reliability are paramount.

Codes often confused with 7304.11
Common mistake. This code is distinct due to its "seamless," "stainless steel," and "oil or gas pipeline" specificities; it should not be confused with 730419 (non-stainless line pipe) or 730424 (stainless casing/tubing for drilling).
Top exporters and importers of HS code 730411, 2025
In 2025, the largest exporter of HS code 730411 in UN Comtrade data was Saudi Arabia, with 20% of world exports; the largest importer in UN Comtrade data was the United Arab Emirates, with about 12% 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).
