Trade Guide

Use HS codes as review candidates, not final decisions.

HS classification depends on material, use, composition, and destination-country rules.

HS Code Notes

Treat HS codes as review candidates.

Documents Dock can keep HS candidates and supporting evidence organized, but it does not provide final HS classification or customs rulings.

Review Checklist

01Start with the WCO 6-digit HS heading, then confirm destination-country digits such as Singapore AHTN or local tariff schedules.

02Collect material, use, composition, model, function, and whether the item is a set, part, accessory, sample, or finished good.

03Do not treat supplier item names as final classification evidence. Ask a declaring agent or customs professional when the result affects duty, permits, or controls.

04Keep the chosen candidate aligned across CI, PL, certificates, permit applications, and declaration handoff notes.
