HEADING

3822

CHAPTER

In plain English

This category includes chemical reagents, diagnostic kits, and certified reference materials used in laboratories, excluding those classified under heading 30.06. The items are divided based on their specific medical applications, with separate groups for tests related to malaria, mosquito-borne diseases like Zika, and blood grouping. Any other diagnostic or laboratory reagents not listed in those specific medical categories fall into a general remaining group. Certified reference materials and other reagents not covered by the specific disease or blood grouping categories are placed in a final catch-all category.

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.
