What is the fastest way to use HS-2, HS-4, HS-6 together?
Use HS-2 to choose family, HS-4 to compare legal scope, and HS-6 to lock the global line before country extensions.
HS-2, HS-4, and HS-6: what stays global
The WCO Harmonized System defines a common structure. Up to six digits (HS-6), classification is the same for every member country. Beyond that, each customs territory publishes its own tariff lines—such as the US HTS, India ITC-HS, or EU TARIC.
HS-2 (chapter)
Two digits (01–97) group broad product families—for example chapter 61 for knitted apparel. Our chapter directory lists every HS-2 title with section context.
HS-4 (heading)
Four digits refine the category within a chapter (e.g. 6105 for knitted shirts). Heading notes and exclusions are where many classification disputes are decided.
HS-6 (subheading)
Six digits are the international “line” used for statistics and FTA comparisons. National schedules extend HS-6 with additional digits for duty, quotas, and reporting—without changing the first six digits.
Quick hierarchy answers
Why do countries show more than 6 digits?
Because HS-6 is global baseline; countries add local digits for duty, trade measures, and reporting requirements.
What should I verify before filing?
Confirm product composition, processing state, and function against heading/subheading notes in your national tariff schedule.
