HS Code 7304.39 – Iron or non-alloy steel (excluding cast iron); seamless, (excluding cold-drawn or cold-rolled), tubes, pipes and hollow profiles of circular cross-section
HS code 7304.39 is the 6-digit subheading for iron or non-alloy steel (excluding cast iron), seamless, (excluding cold-drawn or cold-rolled), tubes, pipes and hollow profiles of circular cross-section. It is used for hot-finished seamless pipes, non-cold-drawn steel tubes, non-cold-rolled hollow sections, industrial fluid conveyance pipes and structural steel tubing.
What HS 7304.39 covers
This HS code encompasses seamless tubes, pipes, and hollow profiles made from iron or non-alloy steel, specifically those not cold-drawn or cold-rolled, and having a circular cross-section. These products are crucial in various heavy industries due to their structural integrity and ability to withstand high pressures without welds. Key importers and exporters include industrial powerhouses like China, Germany, Japan, and the USA, which have robust manufacturing capabilities and significant demand from sectors such as construction, machinery, and general engineering. The trade in these goods is driven by infrastructure development, industrial expansion, and the need for reliable fluid conveyance systems. Understanding the specific manufacturing process (seamless, not cold-worked) is vital for accurate classification and compliance with trade regulations, including anti-dumping duties or CBAM requirements. Their application ranges from structural components to conduits for non-corrosive fluids, making them a foundational element in many industrial supply chains.

Codes often confused with 7304.39
Common mistake. This code is often confused with 730419 (seamless cast iron tubes) or 730429 (seamless tubes for oil/gas pipelines, not cold-drawn), primarily due to the "seamless" and "non-alloy steel" aspects, but the key differentiator is the specific processing (not cold-drawn/rolled) and general application.
Top exporters and importers of HS code 730439, 2025
In 2025, the largest exporter of HS code 730439 in UN Comtrade data was China, with 36% of world exports; the largest importer in UN Comtrade data was Germany, with 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 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).
