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).
