HS-4 · Heading
7304 — Tubes, pipes and hollow profiles, seamless, of iron (other than cast iron) or steel
Chapter 73: Articles of iron or steel
Plain-language overview
Use HS-4 7304 when importing seamless tubes, pipes, and hollow profiles made of iron or steel, such as a shipment of stainless steel line pipes for oil pipelines. This heading covers various types of seamless products, primarily used in the oil and gas industry.
When distinguishing between HS-6 lines, consider the material composition and intended use. For example, if you're dealing with seamless line pipes specifically made of stainless steel, you would use HS-6 730411. In contrast, if the pipes are made of regular iron or steel, HS-6 730419 would apply.
For drilling applications, the choice between HS-6 lines hinges on whether the material is stainless steel or not. Use HS-6 730422 for stainless steel drill pipes, while HS-6 730423 is for those made from non-stainless iron or steel.
When it comes to cold-drawn or cold-rolled tubes, HS-6 730431 applies to non-alloy steel, while HS-6 730441 covers stainless steel options. Make sure to check the specifications to select the correct subheading.
