Tariff classification should not begin with a keyword search and end with the first plausible code. A defensible result starts with verified product facts, applies the relevant rules and preserves the reasoning and evidence behind the decision.
Build a product fact pack
Collect objective characteristics: function, materials, construction, operating principle, degree of completion and presentation context. Use drawings, specifications, photographs and supplier statements. Resolve technical gaps before selecting a code.
Identify and compare candidates
Record plausible headings and compare legal wording, section and chapter notes, inclusions and exclusions. Keeping rejected alternatives shows why the selected heading is stronger and makes future review more efficient.
Apply the classification logic
Work through the General Rules for Interpretation in sequence. Classification begins with heading terms and legal notes; later rules address incomplete goods, mixtures, competing headings, sets and subheadings. Similar rulings are useful only when decisive characteristics genuinely match.
Approve, use and review
Record the code, description, rationale, sources, assumptions, reviewer and date. Link the approved decision to the product master. Trigger review after changes to design, material, function, supplier or tariff nomenclature; higher-risk cases may justify specialist advice or binding information.

Frequently asked questions
What professionals ask
What is an HS code?
An HS code is the internationally harmonised six-digit classification used as the foundation for customs tariffs and trade statistics. Countries may add further digits for national tariff purposes.
How do I find the correct HS code for a product?
Start with verified technical facts, compare candidate headings and legal notes, apply the General Rules for Interpretation in sequence and document why the selected code is stronger than the alternatives.
When should an HS classification be reviewed?
Review it when the product's design, material, function, presentation or supplier changes, and when the relevant tariff nomenclature is updated.
