Harmonized System Code Classification

The first two digits of the HS code "73" represent steel products.

Specifically, this chapter covers the following main contents:

• Steel structural components: For example, bridges, buildings, towers, etc.
• Cast iron products: For example, pipes, pipe fittings, radiators, etc.
• Steel containers: For example, cans, drums, boxes, etc.
• Steel nails, screws, bolts, nuts, etc., fasteners
• Steel wire, ropes, chains, etc.
• Other steel products

Reason for classification:

The establishment of the "73" chapter is to classify and manage various products made of steel materials. Steel is an important industrial basic material, widely used in construction, machinery, transportation, energy, and other fields. Therefore, a separate chapter is set up to classify steel products, which facilitates customs statistics, tariff collection, and trade management.

In short, as long as the product's main material is steel and it belongs to structural components, containers, fasteners, steel wire, etc., it is usually classified into the "73" chapter.

If you can provide a more detailed product description, I can more accurately determine its HS code.

The first four digits of the HS code 7308 represent the following classification and meaning:

Classification: Steel structures and parts

Meaning: Includes:

• Structures (excluding prefabricated buildings under tax number 9406) and their parts, such as bridges and bridge sections, locks, towers, grid masts, roofs, roof frames, doors and windows and their door and window frames and thresholds, louvers, columns and pillars.
• Steel plates, rods, angles, profiles, sections, tubes, etc., prepared for structures.

6-digit explanation: HS code: 7308.30

Classification: Parts and components of steel structures

Specific meaning:

• Steel structures (excluding prefabricated buildings under tax number 9406) and their parts (e.g., bridges and bridge sections, locks, towers, grid masts, roofs, roof frames, doors and windows and their door and window frames and thresholds, louvers, railings, columns and pillars)
• Steel plates, rods, angles, profiles, sections, tubes, etc., prepared for structures
• Specific sub-classification: Doors, windows and their door and window frames and thresholds; others; others

8-10 digit explanation: hscode: 7308305015 Classification: Iron or steel products of structures (excluding prefabricated buildings under tax number 9406) and their parts (e.g., bridges and bridge sections, locks, towers, grid masts, roofs, roof frames, doors and windows and their door and window frames and thresholds, louvers, columns and pillars); iron or steel plates, rods, angles, profiles, sections, tubes, etc., prepared for structures: --> Doors, windows and their door and window frames and thresholds: --> Others --> Windows and their door frames

Explanation: This HS code is classified as iron or steel structures and their parts, specifically a sub-classification of doors, windows and their door and window frames and thresholds, further classified as "others" and "windows and their door frames."

Product examples: * Steel window frames * Steel door frames * Steel window sashes * Steel door sashes * Steel window grids * Steel door grids
