HS Code 7304.49 – Steel, stainless; (excluding cold-drawn or cold-rolled), tubes pipes and hollow profiles of circular cross-section
HS code 7304.49 is the 6-digit subheading for steel, stainless, (excluding cold-drawn or cold-rolled), tubes pipes and hollow profiles of circular cross-section. It is used for hot-finished stainless steel pipes, seamless stainless steel tubes (not cold-worked), industrial stainless hollow profiles, high-temperature stainless pipes and marine-grade stainless tubing.
What HS 7304.49 covers
This HS code pertains to seamless tubes, pipes, and hollow profiles of circular cross-section made from stainless steel, specifically those that have not undergone cold-drawing or cold-rolling processes. These hot-finished or otherwise processed seamless stainless steel products are traded globally for applications requiring excellent corrosion resistance and high-temperature strength, but where the ultra-precise dimensions or surface finish of cold-worked products are not strictly necessary. Key industries utilizing these goods include petrochemicals, power generation, marine engineering, and heavy industrial construction. Countries with significant heavy industries and infrastructure projects, such as China, India, the United States, and various European nations, are major importers and exporters. The trade volume is driven by large-scale industrial projects and the demand for durable, corrosion-resistant piping in less demanding precision applications compared to their cold-worked counterparts.

Codes often confused with 7304.49
Common mistake. This code is distinct from 730441 (cold-drawn/rolled stainless steel) by the absence of cold-working, and from 730640 (welded stainless steel tubes) by being seamless.

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).
