HS Code for General Alloy Steel Tubes
TL;DR: **HS code for general alloy steel tubes** falls under 7304 series in 2025, covering seamless pipes and tubes; key codes like 7304.51 ensure tariff compliance amid regional updates like GCC 12-digit shifts and US de minimis changes.
What Is the HS Code for General Alloy Steel Tubes?
The HS code for general alloy steel tubes standardizes global trade classification. Managed digit codes under Chapter 73 apply to iron and steel products.
- Chapter 73: Articles of iron or steel
- Heading 7304: Tubes, pipes and hollow profiles, seamless, of iron or steel
- Alloy Steel Definition: Contains elements like chromium or nickel exceeding 1.5%
- 2025 Relevance: No WCO changes until 2027, but national updates impact imports
- Global Adoption: Over 200 countries use HS codes for customs clearance
Accurate classification prevents delays in international shipping of alloy steel tubes.
Primary HS Code for General Alloy Steel Tubes in 2025
Key HS codes for general alloy steel tubes center on 7304 subheadings. These ensure proper tariff rates and compliance.
| HS Code | Description | Application | 2025 Notes |
|---|
| 7304.51 | Alloy steel tubes, cold-drawn or cold-rolled | Industrial, mechanical | GCC 12-digit expansion |
| 7304.59 | Other alloy steel seamless tubes | General use | US HTS mandatory |
