HS code library & structure check

Query the official UN Comtrade HS 2022 (H6) library by code, English description, or hierarchy browse — and run an offline length/hierarchy check against destination structures.

Library source: official UN Comtrade HS classification (H6 = HS 2022, English). Structure check below is offline length/hierarchy only — separate from the library.

HS code library (UN Comtrade official)

Official code library · H6 / HS 2022

Exact code (e.g. 0101 or 8471), English description keyword (min 2 chars), or parent browse (TOTAL for chapters, 2-digit for headings, 4-digit for subheadings). Results capped; no full export. Descriptions are English only.

Structure / length check (offline)

Offline structure · no library

Spaces, dots, and hyphens are removed before counting digits. Select the structure used by the destination declaration or tariff reference; the China 8-digit tariff-line reference is listed separately from the 10-digit code.

Basis: WCO HS 2022 uses 6 digits; the table adds disclosed regional and national extensions from the linked customs authorities.
