Harmonized System Code Classification

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

Specifically, this chapter includes 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, 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 from 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 summary, as long as the main material of the product 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 explanation: 7322: Non-electric central heating radiators and their parts (iron or steel); non-electric air heaters and air distributors (including distributors that can distribute fresh air or regulate air), which include motor-driven fans or blowers, and their parts (iron or steel).

6-digit explanation: HS code: 7322.11

Classification: Central heating non-electric radiators and their parts (iron or steel); air heaters and air distributors (including distributors that can distribute fresh air or regulate air), non-electric, containing motor-driven fans or blowers, and their parts (iron or steel).

Specific meaning: Covers radiators made of cast iron and their parts.

8-10 digit explanation: hscode: 7322110000 Classification: Iron or steel central heating radiators and their parts; iron or steel air heaters and air distributors (including distributors that can distribute fresh air or regulate air), without electric heating, containing motor-driven fans or blowers, and their parts: Radiators and their parts: Cast iron radiators. Explanation: This HS code belongs to iron or steel central heating radiators and their parts, specifically cast iron radiators. It includes non-electric heating, with motor-driven fans or blowers, used in central heating systems, or including distributors that can distribute fresh air or regulate air.

Product examples: * Cast iron radiator * Steel radiators with motor-driven fans * Central heating system components made of cast iron * Air distributors with non-electric heating * Parts for non-electric radiators made of cast iron
