HS Code for Cold-drawn stainless steel tubes

The classification for cold-drawn stainless steel tubes is HS code 7304.41. This classification is part of the broader Heading 7304, which covers seamless tubes and pipes of iron or steel. To fall under 7304.41, the product must first meet the definition of "stainless steel" provided in Note 1(e) to Chapter 72, which requires a chromium content of 10.5% or more by weight and a maximum carbon content of 1.2%. Secondly, the tube must be seamless, meaning it is not formed by welding or joining edges. Thirdly, the tube must have been cold-drawn or cold-rolled. Cold-drawing involves pulling the steel through a die at room temperature, which enhances the mechanical properties, increases tensile strength, and provides a high-quality surface finish. This code is specific to tubes and pipes of circular cross-section. The distinction between cold-drawn and hot-finished is vital; hot-finished stainless steel tubes are classified under 7304.49. Importers and exporters must provide mill test reports to verify the chemical composition (to prove it is stainless) and the manufacturing method (to prove it is seamless and cold-drawn) to ensure correct classification. This code is widely used for high-precision tubing in the medical, aerospace, and chemical processing industries where the corrosion resistance of stainless steel and the precision of cold-drawing are required.

Products Included

Common Misclassification

The most frequent error is using 7304.49, which is for hot-finished seamless stainless tubes. Another common mistake is classifying welded stainless steel tubes under this code; welded versions belong in 7306.40. Additionally, tubes made of other alloy steels (not stainless) should be classified under 7304.51.

FAQ

What is the HS code for cold-drawn stainless steel tubes?

The HS code for seamless, cold-drawn or cold-rolled stainless steel tubes of circular cross-section is 7304.41.

What is the difference between 7304.41 and 7304.49?

7304.41 is specifically for tubes that have been cold-drawn or cold-rolled, while 7304.49 is for those that are hot-finished or otherwise processed.
