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, oil drums, cans, etc.
• Steel nails, screws, nuts, washers, and other fasteners
• Steel wire, steel ropes, steel 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 with a wide range of applications, so a separate chapter is needed for classification, which facilitates customs statistics, tariff collection, and trade management.

In short, if your product is mainly composed of steel and belongs to types such as structural components, containers, fasteners, steel wire, etc., it is likely to fall under the HS code "73" chapter.

For a more accurate determination, please provide more detailed product descriptions, such as the specific use, material, specifications, etc.
