HS Code for Cold-rolled stainless steel pipes

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.

Products Included

• Seamless stainless steel precision tubes
• Cold-drawn stainless steel hydraulic pipes
• Cold-rolled circular stainless hollow sections
• Seamless stainless steel instrumentation tubing

Common Misclassification

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.

FAQ

What is the HS code for cold-rolled stainless steel pipes?

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

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.
