Stainless steel tubes are essential components widely used in industries such as construction, automotive, aerospace, and manufacturing. For importers, exporters, and customs officials, knowing the correct Harmonized System (HS) code for stainless steel tubes is crucial for proper classification, tariff assessment, and compliance with international trade regulations. This comprehensive article explores the HS codes applicable to stainless steel tubes, their classifications, variations, and practical tips for identifying the right code for your products.
The Harmonized System (HS) is an internationally standardized system of names and numbers to classify traded products. It is maintained by the World Customs Organization (WCO) and used by more than 200 countries worldwide. HS codes are structured in a hierarchical manner:
- Chapter: The first two digits represent the chapter (e.g., Chapter 73 covers "Articles of Iron or Steel").
- Heading: The next two digits specify the heading within the chapter.
- Subheading: The following two digits further define the product category.
- Additional digits: Some countries add more digits for further classification.
For stainless steel tubes, the HS codes generally fall under Chapter 73, which covers iron and steel products.
Stainless steel tubes are primarily classified under two main headings depending on their manufacturing type: seamless or welded tubes.
- HS Code 7304 covers tubes, pipes, and hollow profiles that are seamless, made of iron or steel.
- Under this heading, stainless steel tubes have more specific subheadings based on diameter and other characteristics.
- For example, HS Code 73044983 is used for seamless stainless steel tubes with an external diameter not exceeding 168.3 mm.
- Larger diameters have different sub-codes such as 73044985 and 73044989.
- HS Code 7306 is for other tubes, pipes, and hollow profiles (including welded, riveted, or similarly closed), made of iron or steel.
- Welded stainless steel tubes with circular cross-section fall under HS Code 73064080.
- Rectangular or square welded stainless steel tubes with wall thickness 4 mm or more are classified under HS Code 73066030.
- Tubes with less than 4 mm wall thickness fall under HS Code 73066070.
- Tube or pipe fittings such as couplings, elbows, and sleeves made of stainless steel are classified under HS Code 73072900.
| HS Code | Description | Notes |
|---|---|---|
| 73041110 | Seamless stainless steel tubes and pipes | Specific to certain seamless tubes |
| 73044983 | Seamless stainless steel tubes, external diameter ≤ 168.3 mm | Common for smaller diameter seamless tubes |
| 73064080 | Welded stainless steel tubes, circular cross-section | For welded tubes with diameter ≤ 406.4 mm |
| 73066030 | Welded stainless steel tubes, rectangular/square cross-section, wall thickness ≥ 4 mm | Structural tubes |
| 73066070 | Welded stainless steel tubes, rectangular/square cross-section, wall thickness < 4 mm | Thinner wall tubes |
| 73072900 | Tube or pipe fittings of stainless steel | Includes flanges, couplings |
Choosing the correct HS code depends on several factors:
- Manufacturing Method: Whether the tube is seamless or welded.
- Cross-Section Shape: Circular, square, or rectangular.
- Wall Thickness: Tubes with different wall thicknesses have different codes.
- External Diameter: Size thresholds affect classification.
- Material Composition: Presence of nickel, molybdenum, or other alloying elements can influence codes in some countries.
- End Use: Some tubes used for oil and gas pipelines have separate classifications.
1. Determine the Manufacturing Process: Identify if your tube is seamless or welded.
2. Measure Dimensions: Note the external diameter and wall thickness.
3. Check Cross-Section: Is it circular, square, or rectangular?
4. Review Material Specifications: Confirm stainless steel grade and alloy content.
5. Consult Customs or Trade Databases: Use official HS code lookup tools or consult with customs brokers.

- Customs Compliance: Prevents delays and penalties during import/export.
- Correct Duty Assessment: Ensures you pay the appropriate tariffs.
- Trade Statistics: Helps governments track trade flows accurately.
- Facilitates Trade Agreements: Proper classification is essential under free trade agreements.
| Stainless Steel Grade | Typical HS Code Range | Notes |
|---|---|---|
| Grade 304, 304L | 7306.40.1015 (US HTS) | Welded tubes with nickel content |
| Grade 316, 316L | 7306.40.1010 (US HTS) | Contains molybdenum, higher corrosion resistance |
| Other Grades | Varies under 7304 or 7306 | Depends on specifications and country |
- China is the largest importer of stainless steel tubes globally.
- Trade data platforms provide detailed import/export shipment statistics by HS codes.
- Monitoring HS code trends helps businesses identify market demands and competitor activities.
Understanding the HS code for stainless steel tubes is vital for anyone involved in international trade of these products. The classification depends on factors like manufacturing process, tube shape, dimensions, and material composition. Seamless tubes are generally classified under HS Code 7304, while welded tubes fall under 7306, with additional codes for fittings under 7307. Accurate classification ensures compliance, correct tariff application, and smooth customs clearance. Utilizing official resources and consulting trade experts can help you identify the precise HS code for your stainless steel tubes, facilitating efficient global trade operations.
The general HS codes for stainless steel tubes are under Chapter 73, specifically 7304 for seamless tubes and 7306 for welded tubes.
Seamless tubes fall under HS Code 7304, while welded tubes are classified under HS Code 7306, with further subcategories based on shape and size.
Yes, stainless steel tube fittings such as couplings and elbows are classified under HS Code 7307.
Wall thickness determines subheadings within welded stainless steel tubes; tubes with wall thickness 4 mm or more have different codes than those with less than 4 mm.
You can find exact HS codes by consulting customs websites, trade data platforms, or using HS code lookup tools provided by customs authorities.
