At a Glance

  • The General duty rate for HTS 293339 is 5.8% · 16 statistical suffixes · 2 duty-free.
  • 9 sub-classifications offer Special (FTA) rate preferences — check the Special column for USMCA, KORUS, and other FTA eligibility.
  • This code falls under a chapter covering organic chemicals including hydrocarbons, alcohols, acids, esters, amines, pharmaceutical intermediates, and laboratory reagents.

HTS Chapter 29 Classification Guide: Organic Chemicals

Chapter 29 covers organic chemicals including hydrocarbons, alcohols, acids, esters, amines, pharmaceutical intermediates, and laboratory reagents. This is the largest chapter by number of subheadings in the chemical section. Classification requires identifying the specific organic compound by its chemical structure and functional groups.

Common Misclassification Errors

  • Classifying pharmaceutical end products under Chapter 29 — finished medicines and pharmaceutical preparations belong in Chapter 30, not Chapter 29
  • Confusing isomers — the HTS often has separate subheadings for different isomers of the same compound, and incorrect isomer identification leads to misclassification
  • Not checking for TSCA, FDA, and DEA regulatory requirements, which vary significantly depending on the specific compound and end use

Duty Calculation Tips for HTS 293339

Many organic chemical intermediates qualify for duty-free treatment. Section 301 List 2 (25%) applies to many Chinese-origin organic chemicals. Pharmaceutical intermediates may qualify for duty-free treatment under the WTO Pharmaceutical Agreement. TSCA, FDA, and DEA compliance must be verified for each compound. Consider sourcing from India and EU for lower duty burden.

What Importers Need to Know About HTS Chapter 29

This subheading falls under an HTS chapter covering organic chemicals including hydrocarbons, alcohols, acids, esters, amines, pharmaceutical intermediates, and laboratory reagents. Importers of these products should be aware of the following trade compliance considerations:

Organic chemical imports may be subject to TSCA, FDA (if pharmaceutical grade), or DEA (controlled precursors). Verify regulatory status for your specific compound.

For the specific subheading HTS 293339, we recommend you:

  1. Verify the correct 10-digit statistical suffix — even within a 6-digit subheading, duty rates can differ significantly between suffixes
  2. 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
  3. 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
  4. Consult CBP resources — for binding classification rulings, CBP's National Commodity Specialist Division provides written determinations

Chapter 29 Frequently Asked Questions

How are organic chemicals classified differently from pharmaceutical products?

Organic chemicals (Chapter 29) are raw or intermediate chemical compounds. Pharmaceutical products (Chapter 30) are finished medicines, vaccines, and medical preparations. The distinction is based on the product's composition and presentation — a bulk chemical used as a pharmaceutical intermediate is Chapter 29; the same chemical put up as measured doses in retail packaging is Chapter 30.

Do organic chemical imports require TSCA compliance?

Yes. Most organic chemicals imported into the US must be listed on the TSCA Inventory or qualify for an exemption. Importers must certify TSCA compliance at entry. Chemicals not on the TSCA Inventory require EPA premanufacture notice (PMN) review before importation. This process can take 90+ days.

What is the WTO Pharmaceutical Agreement and how does it affect duty rates?

The WTO Pharmaceutical Agreement (also known as the Pharma Agreement) provides duty-free treatment for specified pharmaceutical products, active ingredients, and intermediates. Many organic chemicals used in pharmaceutical manufacturing qualify for duty-free treatment under this agreement, regardless of FTA status.

Are Chinese organic chemicals subject to Section 301 tariffs?

Yes. Many Chinese-origin organic chemicals face Section 301 List 2 additional duties of 25%. This includes many hydrocarbons, alcohols, carboxylic acids, and other compounds. Check the specific HTS subheading against USTR's tariff lists. Some pharmaceutical-grade chemicals may be excluded.

How do I classify a chemical that has multiple functional groups?

Organic chemicals with multiple functional groups are classified under the heading of the functional group that gives the compound its principal character, following the ordering of headings in Chapter 29. If the compound could fall under multiple headings, the heading occurring last in numerical order applies (GRI 3(c)). Consult a chemist for complex compounds.

Importing Under HTS 293339: 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.
