Duty Calculation Tips for HTS 380590
Chapter 38 base duties are generally low (0–6.5%), and many chemical preparations are duty-free under the WTO Chemical Tariff Harmonization and ITA. However, anti-dumping duties are common on Chinese-origin chemical products, and Section 301 List 1 (25%) targeted many chemicals and intermediates from China. A proprietary formulation in 3824 often escapes the higher specific duties that apply to a named chemical compound in Chapter 29 — this is why correct 'chemically defined vs. preparation' classification is both a duty lever and a compliance risk.
Importing Under HTS 380590: What Importers Ask
Does this chemical product require TSCA certification?
Chemical products under this HTS chapter are subject to EPA TSCA (Toxic Substances Control Act) requirements. Verify your substance is listed on the TSCA Inventory. New chemicals require PMN (Pre-Manufacture Notice) submission to EPA at least 90 days before import.
How are pharmaceutical intermediates classified differently from finished drugs?
Pharmaceutical intermediates generally fall under Chapter 29 (organic chemicals), while finished dosage-form drugs fall under Chapter 30. The distinction affects both duty rates and FDA regulatory requirements — finished drugs face higher scrutiny under CDER/CBER.
What safety data sheet (SDS) requirements apply to chemical imports?
OSHA HazCom Standard requires SDS for hazardous chemical imports. CBP may hold shipments without proper SDS documentation. Ensure your foreign supplier provides GHS-compliant SDS in English. Certain chemicals also require EPA or DEA import certification.

HTS Chapter 38 Classification Guide: Miscellaneous Chemical Products
Chapter 38 is the residual chapter for chemical products not more specifically covered elsewhere in Chapters 28–37. It includes insecticides, rodenticides, fungicides and herbicides (3808), anti-knock preparations and additives for mineral oils (3811), prepared rubber and plastics accelerators (3812), prepared culture media (3821), industrial monocarboxylic fatty acids (3823), prepared binders for foundry molds (3824), and reaction initiators, and the very high-volume product: mixtures and preparations not elsewhere specified or included (3824.99), the classic 'catch-all' for proprietary chemical formulations. Because heading 3824 is residual, the classification rules here stress exhausting Chapters 28–37 and 29 first, and using GRI to find the most specific heading.
Common Misclassification Errors
- Classifying a proprietary chemical mixture under a Chapter 28/29 heading when it is a preparation of heading 3824 — mixtures of two or more constituents that are not separate chemically defined compounds belong in 38
- Classifying finished pesticides and biocides as their active ingredient under Chapter 29 — formulated insecticides/herbicides are heading 3808
- Classifying prepared culture media and laboratory reagents under Chapter 30 pharmaceuticals when they are diagnostic/laboratory chemicals of Chapter 38

Chapter 38 Frequently Asked Questions
What is the difference between Chapter 29 and Chapter 38 chemicals?
Chapter 29 covers separate chemically defined organic compounds. Chapter 38 covers mixtures, preparations, and products not elsewhere specified — including formulations made of two or more constituents. A pure chemical is Chapter 29; a proprietary blend is typically Chapter 38.
Are pesticides and herbicides classified in Chapter 38?
Yes, formulated insecticides, herbicides, fungicides, and similar plant-protection products are classified in heading 3808. The active ingredient alone would be Chapter 29, but the finished formulated product belongs in 3808.
What is heading 3824 and why is it important?
Heading 3824 covers chemical products and preparations of the chemical or allied industries not elsewhere specified. Its subheading 3824.99 is the residual 'catch-all' for proprietary mixtures and preparations, and classification there is common for custom chemical formulations.
Do Chinese chemical products face anti-dumping duties?
Yes. Many Chinese-origin chemical products have been subject to US anti-dumping and countervailing duty orders, and Section 301 List 1 (25%) covered a broad range of chemicals and intermediates. Always check ADD/CVD and Section 301 status for your product.
Are laboratory reagents and culture media classified in Chapter 38?
Prepared culture media for growing microorganisms are classified in heading 3821, and many laboratory diagnostic reagents fall under Chapter 38 as well. Some diagnostic products may instead be classifiable in Chapter 30 or 90 depending on their function.
What Importers Need to Know About HTS Chapter 38
This subheading falls under an HTS chapter covering products classified under this heading of the Harmonized Tariff Schedule. Importers of these products should be aware of the following trade compliance considerations:
Importers should verify classification with CBP or a licensed customs broker. Check whether Section 301, Section 232, or anti-dumping/countervailing duties apply to your product based on country of origin and specific HTS classification.
For the specific subheading HTS 380590, we recommend you:
- Verify the correct 10-digit statistical suffix — even within a 6-digit subheading, duty rates can differ significantly between suffixes
- Check FTA eligibility — if your product qualifies for preferential treatment under USMCA, KORUS, or another FTA, you may reduce or eliminate duties by providing the required origin certification
- Monitor for trade remedy changes — Section 301, Section 232, and anti-dumping duties are updated periodically. A rate that was correct last quarter may have changed
- Consult CBP resources — for binding classification rulings, CBP's National Commodity Specialist Division provides written determinations
