HS Code Lookup Skill

This skill helps classify products into their correct Harmonized System (HS) codes — the international standard for categorizing traded goods used by customs authorities worldwide.

Background

The Harmonized System is maintained by the World Customs Organization (WCO). It uses a hierarchical structure:

• Chapters (2 digits): Broad category (e.g., Chapter 61 = Knitted apparel)
• Headings (4 digits): Narrower group (e.g., 6109 = T-shirts, singlets)
• Subheadings (6 digits): International standard level (e.g., 6109.10 = T-shirts of cotton)
• National lines (8–10 digits): Country-specific (e.g., US HTS uses 10 digits)

The first 6 digits are internationally harmonized. Digits beyond 6 vary by country.
