Data Model

• Sections — 21 top-level groupings (e.g. "Live animals", "Mineral products"). Numbered I–XXI.
• Chapters — 2-digit codes (e.g. "01" = Live animals). Each belongs to one section.
• Headings — 4-digit codes (e.g. "0101" = Live horses, asses, mules). Each belongs to one chapter.
• Commodities — 10-digit codes (e.g. "0101210000" = Pure-bred breeding animals). Declarable items with duty rates and measures.

Hierarchy

Section → Chapter(s) → Heading(s) → Commodity/Commodities

Search

• Exact match — returns a redirect to a specific commodity, heading, or chapter.
• Fuzzy match — returns scored results across chapters, headings, and commodities.

Gotchas

• Chapter IDs are 2-digit strings with leading zeros (e.g. "01", not "1").
• Heading IDs are 4-digit strings (e.g. "0101").
• Commodity IDs are 10-digit strings (e.g. "0101210000").
• Section IDs are integers (1–21).
• Commodity responses include extensive included data (measures, duty expressions, footnotes). The tools extract key fields for readability.
