About chapter 38
Chapter 38 covers chemical products n.e.c. (not elsewhere classified): everything from insecticides and disinfectants to prepared culture media, anti-freeze and industrial additives that don't fit the more specific chemical chapters (28-37). It's a broad, catch-all classification for specialty chemical formulations.
Classification tip: Pesticides and disinfectants in this chapter almost always require separate environmental or agricultural-agency registration in the destination country, in addition to the customs classification.

Codes and descriptions follow the WCO six-digit Harmonized System nomenclature. National tariff schedules extend these to 8–13 digits and set the actual duty rate, so confirm the full code for your destination country with your customs broker before filing.

Chapter 38 FAQ
What does HS code chapter 38 cover?
Chapter 38 of the Harmonized System covers: chemical products n.e.c.. It belongs to section VI (Chemical Products) and contains 27 four-digit headings, 3801–3827.
How many HS codes are in chapter 38?
Chapter 38 contains 27 four-digit headings and 108 six-digit subheadings. Countries subdivide these further (8–13 digits) in their national tariff schedules, so the full national count is larger.
Is HS code 3801 the same in every country?
Yes. The six-digit level of every code in this chapter is harmonised by the World Customs Organization and identical in all member countries. Digits beyond the sixth (for example the US 10-digit HTS or the EU 8-digit CN) are national and set the actual duty rate.
How do I choose the right code within chapter 38?
Work from the four-digit heading down: pick the heading that best matches your product, then the six-digit subheading that matches its material, form or processing. If two codes seem to fit, customs rules (the General Rules of Interpretation) decide, and when in doubt, confirm with your customs broker before filing.
