Harmonized System Code Classification

The first two digits of the HS code "40" represent rubber and articles of rubber.

Specifically, the classification is based on:

• Main component is rubber: Whether it is natural rubber, synthetic rubber, or reclaimed rubber, as long as rubber is the main component, it belongs to this category.
• Diverse forms of products: Including tires, rubber hoses, rubber belts, rubber shoes, rubber seals, rubber sheets, rubber cable sheaths, and various forms of rubber products.
• Excludes products made of other materials: Even if the product contains rubber, if rubber is not the main component, or if rubber is only used as an auxiliary material, it is not classified into this category. For example, textile products containing rubber, plastic products, etc.

In summary, the core classification basis for the HS code "40" is rubber as the main material, and it covers various products made of rubber.

If you want to know more specific sub-classifications, you can provide more detailed HS codes (e.g., 4011, 4012, etc.), and I will do my best to explain them for you.

First four digits explanation: 4008: Vulcanized rubber sheets, plates, strips, rods, and profiles, excluding hard rubber.

Six-digit explanation: HS code: 4008.19

Classification: Vulcanized rubber sheets, plates, strips, rods, and profiles, excluding hard rubber:

• Sub-classification: Cellular rubber:
  • More detailed classification: Other:
    • Most detailed classification: Natural rubber:
      • Specific description: Profiles

This HS code refers to profiles made of natural rubber vulcanized rubber.

8-10 digits explanation: hscode: 4008194000 Classification: Vulcanized rubber sheets, plates, strips, rods, and profiles, other vulcanized rubber: --> cellular rubber: --> other: --> natural rubber: --> other

Explanation: This HS code belongs to the classification of vulcanized rubber sheets, plates, strips, rods, and profiles, further classified as cellular rubber, and is made of natural rubber, finally classified into the "other" category.

Examples of products: * Natural rubber cellular profiles * Natural rubber sponge profiles * Natural rubber foam profiles * Natural rubber cellular rods * Natural rubber cellular strips
