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: For example, bridges, buildings, towers, etc.
• Cast iron products: For example, pipes, pipe fittings, radiators, etc.
• Steel products: For example, steel plates, steel pipes, steel wires, steel nails, bolts, nuts, etc.
• Other steel products: For example, 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, as iron and steel are important industrial raw materials and building materials, with a wide range of product types and applications. By classifying iron and steel products specifically, customs can conduct statistics, collect tariffs, implement trade management, and enforce relevant regulations.

In short, any product whose main component is made of iron or steel is typically classified into the "73" chapter.

The first four digits of the HS code 7302 represent iron or steel materials used for railway or tramway track laying, specifically including:

• Rails, guide rails, and rack rails
• Switch blades, crossover switches, point rails, and other crossover switch components
• Sleepers (rail ties)
• Fish plates
• Rail seats, rail wedges, base plates
• Rail clamps, rail beds
• Sleepers and other specialized materials used for connecting or fixing rails

6-digit explanation:
HS code: 7302.90

Classification: Iron or steel materials used for railway or tramway track laying: rails, rack rails, and rack switches, switches, crossover switches, switch rods, and other crossover components, sleepers (rail ties), fish plates, rail seats, rail wedges, base plates, rail clamps, rail beds, rail connectors, and other specialized rail connectors or fixing components: Other: Other

Meaning: This HS code covers iron or steel materials used for railway or tramway track laying, including rails, rack rails, rack switches, switches, crossover switches, switch rods, sleepers, fish plates, rail seats, rail wedges, base plates, rail clamps, rail beds, and other specialized materials used for connecting or fixing rails. Specifically, 7302.90 refers to the "other" category within the above materials, and further to the "other" subcategory within that "other" category.

8-10 digit explanation:
HS code: 7302901000
Classification: Materials for railway or tramway track laying, including: rails, rack rails, sleepers, fish plates, rail clamps, base plates, and specialized materials for connecting or fixing rails
Explanation: This HS code falls under the category of materials for railway or tramway track laying, specifically including rails, rack rails, sleepers, fish plates, rail clamps, base plates, and specialized materials for connecting or fixing rails. It is further subdivided into the "other" category under "sleepers."

Examples of products: * Steel rails * Fish plates * Rail sleepers * Rail clamps * Base plates * Switch components * Rail wedges * Rail connectors * Rail beds * Track fasteners
