Harmonized System Code Classification

7305905000 is an HS code used for classifying specific types of steel and iron pipes and profiles. This code applies to pipes and profiles with a circular cross-section, an external diameter exceeding 406.4 mm, made of alloy steel, and produced by methods such as welding, riveting, or similar enclosed methods. These are not precision tubes and fall under the "other" category within the 7305 classification.

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

• Large-diameter steel pipes for construction: Used in building infrastructure, bridges, or industrial structures.
• Alloy steel pipes for oil and gas transportation: Used in pipelines for transporting crude oil or natural gas.
• Custom-made alloy steel profiles for industrial machinery: Used in the manufacturing of heavy machinery or equipment.
• Alloy steel tubes for pressure vessels: Used in the production of large pressure vessels or storage tanks.
• Welded alloy steel pipes for water supply systems: Used in large-scale water supply or drainage systems.

These examples are for reference only, and the actual product classification should be determined based on its specific technical parameters and usage.
