Harmonized System Code Classification

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

Specifically, this chapter covers the following main contents:

• Steel structural components: Such as bridges, buildings, towers, etc.
• Cast iron products: Such as pipes, pipe fittings, radiators, etc.
• Steel products: Such as steel plates, steel pipes, steel wires, nails, bolts, nuts, etc.
• Other iron and steel products: Such as springs, chains, fasteners, cutting tools, etc.

Reason for classification:

The establishment of the "73" chapter is to classify and manage various products made of iron and steel. These products usually have the following characteristics:

• Main material is iron or steel: The core component of the product is iron or steel.
• Wide range of applications: Iron and steel products are widely used in the construction, machinery, transportation, energy, and other industries.
• Diverse manufacturing processes and product forms: Iron and steel products can be manufactured through casting, forging, rolling, welding, and other processes, and can present various forms and functions.

Therefore, the first two digits of the HS code "73" are used to identify and classify all products made primarily of iron or steel.

If you can provide a more specific HS code (such as 7304, 7310, etc.), I can provide a more detailed classification explanation.

The first four digits explanation: 7314: Woven fabrics (including endless bands), grilles, nets, and fences made of iron wire or steel wire; expanded metal made of iron wire or steel wire.

6-digit explanation: Classification: Woven fabrics made of iron wire or steel wire, grilles, nets, and fences; expanded metal made of iron wire or steel wire

Specific meaning:

• 7314.12: Among woven fabrics:
  • 7314.12: Endless bands used for machinery, made of stainless steel:
    • 7314.12: With less than 36 threads per linear centimeter in the warp and weft direction:
      • 7314.12: Other

8-10 digit explanation: hscode: 7314129000 Classification: Woven fabrics (including endless bands), grilles, nets, and fences made of iron wire or steel wire; expanded metal made of iron wire or steel wire: --> Woven fabric: --> Endless bands used for machinery, made of stainless steel: --> With less than 36 threads per linear centimeter in the warp and weft direction, other Explanation: This HS code corresponds to woven fabrics (including endless bands), grilles, nets, and fences made of iron wire or steel wire; expanded metal made of iron wire or steel wire, specifically referring to endless bands used for machinery, made of stainless steel, with less than 36 threads per linear centimeter in the warp and weft direction, other products.

Product examples: * Stainless steel woven mesh for industrial filters * Stainless steel endless bands used in conveyor systems * Stainless steel woven fabric for protective barriers * Stainless steel grilles for machinery parts * Stainless steel expanded metal sheets for construction applications
