Product classification
HS code for Cold-rolled stainless steel pipes: 7304.41
Steel, stainless, cold-drawn or cold-rolled (cold-reduced), tubes and pipes of circular cross-section.
Classification of cold-rolled stainless steel pipes under HS 7304.41
HS code 7304.41 covers seamless tubes, pipes, and hollow profiles made of stainless steel that have been cold-drawn or cold-rolled. This classification falls under Chapter 73, which is dedicated to articles of iron or steel, rather than the raw materials covered in Chapter 72. The "seamless" designation is a primary requirement, meaning the pipe must be manufactured without a welded seam, typically through processes like hot-piercing followed by cold-finishing. Stainless steel is defined as alloy steel containing, by weight, 1.2% or less of carbon and 10.5% or more of chromium. The cold-finishing process (cold-drawing or cold-rolling) is a secondary operation that provides the pipe with exceptional dimensional accuracy, a high-quality surface finish, and enhanced mechanical properties. These pipes are frequently used in demanding environments such as chemical processing, aerospace, and high-pressure hydraulic systems where the integrity of a seamless structure is critical. The circular cross-section is another defining characteristic for this specific subheading. Distinguishing between cold-finished and hot-finished seamless pipes is necessary because the manufacturing complexity and cost of cold-finished products are generally higher, often reflected in different trade statistics and customs valuations.

Codes often confused with 7304.41
Common mistake. This code is frequently confused with 7306.40, which covers welded stainless steel pipes. It is also often misclassified with 7304.49, which is for hot-finished (hot-rolled) seamless stainless pipes. Additionally, line pipes used for oil and gas pipelines may fall under 7304.11 if they meet specific API standards.
Top exporters and importers of HS 730441 (the code used for cold-rolled stainless steel pipes), 2025
In 2025, the largest exporter of HS 730441 (the code used for cold-rolled stainless steel pipes) in UN Comtrade data was China, with 31% of world exports; the largest importer in UN Comtrade data was the United States, with 11% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 730441, not only cold-rolled stainless steel pipes.

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).

Questions about cold-rolled stainless steel pipes
What is the HS code for Cold-rolled stainless steel pipes?
The HS code for Cold-rolled stainless steel pipes is 730441 (Steel, stainless; cold-drawn or cold-rolled (cold-reduced), tubes and pipes of circular cross-section). The HS code for seamless, cold-drawn or cold-rolled stainless steel pipes of circular cross-section is 7304.41.
How do I classify Cold-rolled stainless steel pipes for customs?
Cold-rolled stainless steel pipes is classified under HS code 730441 — Steel, stainless; cold-drawn or cold-rolled (cold-reduced), tubes and pipes of circular cross-section. This is a 6-digit subheading level code.
What is the difference between 7304 and 7306?
Heading 7304 is strictly for seamless tubes and pipes, whereas heading 7306 covers tubes and pipes that are welded, riveted, or similarly closed.
Which countries are the top exporters of cold-rolled stainless steel pipes (HS 730441)?
In 2025, the top exporters of HS 730441 (the code used for cold-rolled stainless steel pipes) in UN Comtrade data were China ($975M, 31% of world exports), Japan ($332M) and Czechia ($297M). World exports came to about $3.1B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
