HS-6 · Subheading
730539
Iron or steel (excluding cast iron); tubes and pipes (other than line pipe or casing of a kind used for oil or gas pipelines), welded (not longitudinally welded), having circular cross-sections, external diameter exceeds 406.4mm, (not seamless)
Heading 7305 — Iron or steel (excluding cast iron); tubes and pipes (e.g. welded, riveted or similarly closed), having circular cross-sections, external diameter of which exceeds 406.4mm, not seamless
Chapter 73: Articles of iron or steel
Plain-language overview
Use HS-6 730539 when importing or exporting welded iron or steel tubes and pipes that have a circular cross-section and an external diameter exceeding 406.4mm. For example, if you're shipping large diameter steel pipes used in construction or industrial applications, this is the correct code.
This code specifically applies to welded tubes and pipes that are not seamless and are not intended for use in oil or gas pipelines. In contrast, HS-6 7305XX covers similar products but may include different specifications or uses, such as longitudinally welded pipes.
When classifying your product, ensure that the external diameter exceeds 406.4mm, as this is a key criterion for HS-6 730539. If your product is seamless or has a different diameter, you may need to look at other codes under the same heading.
If you're dealing with tubes and pipes that are used for structural purposes, such as in building frameworks, this HS-6 code will be relevant. However, if your product is designed for oil or gas applications, you should refer to other specific codes for those uses.

- What types of products are classified under HS-6 730539?
- HS-6 730539 covers welded iron or steel tubes and pipes that have a circular cross-section and an external diameter exceeding 406.4mm, excluding seamless pipes.
- Is HS-6 730539 applicable for oil and gas pipelines?
- No, HS-6 730539 is specifically for welded tubes and pipes not intended for oil or gas pipelines. You should look for other codes for those applications.
- What is the significance of the 406.4mm diameter in HS-6 730539?
- The 406.4mm diameter is a critical threshold; products must exceed this measurement to qualify for classification under HS-6 730539.
- Can I use HS-6 730539 for seamless pipes?
- No, HS-6 730539 is only for welded pipes. If your product is seamless, you will need to classify it under a different HS code.
- What are some examples of shipments that would use HS-6 730539?
- Examples include large welded steel pipes for construction, industrial machinery, and water transportation systems.
- How do I ensure my product meets the criteria for HS-6 730539?
- Make sure your product is a welded tube or pipe, has a circular cross-section, and the external diameter exceeds 406.4mm.
- Are there any specific packaging requirements for HS-6 730539 products?
- While there are no specific packaging requirements tied to the HS code itself, ensure that the products are securely packaged to prevent damage during transport.
- What should I do if my product dimensions are close to the 406.4mm limit?
- If your product is very close to the limit, measure carefully. If it exceeds 406.4mm, you can classify it under HS-6 730539; if not, look for alternative codes.
