Harmonized System Code Classification

7306.40.10.90 is a specific HS code used for classifying certain types of stainless steel tubes. Here's a detailed breakdown of its classification:

• Chapter 73: Steel articles.
• Heading 7306: Other tubes, pipes and hollow profiles (e.g., open-seamed or welded, riveted or similarly closed), of iron or steel.
• Subheading 7306.40: Other, welded, circular section, stainless steel: wall thickness < 1.65 mm: other: other: external diameter over 114.3 mm but not exceeding 406.4 mm: other.
• Tariff Line 7306401090: Other tubes, pipes and hollow profiles (e.g., open-seamed or welded, riveted or similarly closed), of iron or steel: other, welded, circular section, stainless steel: wall thickness less than 1.65 mm: nickel content exceeding 0.5% (by weight): other.

This classification applies to welded stainless steel tubes with a circular cross-section, a wall thickness less than 1.65 mm, and a nickel content exceeding 0.5% by weight. It does not specify any requirements for molybdenum content.

Examples of products that may fall under this HS code include:

• Stainless steel welding tubes used in construction or industrial applications
• Stainless steel tubes for plumbing or HVAC systems
• Stainless steel tubes used in the manufacturing of machinery or equipment
• Stainless steel tubes used in the production of automotive parts or components
• Stainless steel tubes used in the production of medical devices or equipment
