6-digit subheadings (4)
Official HS 2022 subheading texts. National tariff schedules subdivide these further (8-10 digit lines) and set the actual duty rates.
Chapter 38 classification notes
Chapter 38 includes pesticides (3808) which are subject to FAO Rotterdam Convention prior-informed-consent for many active ingredients. Diagnostic reagents (3822) often dual-classified with Chapter 30 medicines.
Frequent misclassification in this chapter
Insect repellent (DEET) — depending on form, 3808 (commercial pesticide) vs. 3304 (cosmetic preparation).
Classification certainty
The 6-digit level shown here is the internationally harmonised layer. Duty rates attach to national 8-10 digit tariff lines, which differ by country — use the duty calculator for lane estimates. For binding certainty, request a ruling from the destination customs authority.
