Duty Rates
General (Column 1 - MFN)
Free
This item enters the United States duty-free. No import duty is charged regardless of origin country.
Column 2 Rate (Non-Tariff Treaty Countries)
This rate applies to countries without normal trade relations (most-favored-nation status) with the United States:
15.4¢/kg + 53.5%
Column 2 rates are substantially higher than Column 1 rates and are rarely applied in modern international trade due to most-favored-nation agreements.
What HTS 2921.30.05.00 Covers
This code covers the specific organic chemical 1,3-bis(aminoethyl)cyclohexane, a cycloaliphatic diamine. It sits under heading 2921 for amine-function compounds, in the subheading for cyclanic, cyclenic and cycloterpenic mono- or polyamines. The code applies to the pure or commercial-grade chemical itself, typically shipped in bulk drums, totes or tank containers.
Notes for Importers
This diamine is used mainly as a curing agent for epoxy resins and as an intermediate for coatings, adhesives and polyamide production. Because the code names a single chemical, only that exact CAS substance belongs here; other cyclohexane-based diamines such as isophoronediamine fall under neighboring provisions within 2921.30. If the chemical is imported already formulated into a mixture or prepared curing agent, it usually shifts to Chapter 38 instead.

Frequently Asked Questions
What products are classified under 2921.30.05.00?
Only the specific chemical 1,3-bis(aminoethyl)cyclohexane, a cycloaliphatic diamine used chiefly as an epoxy curing agent and chemical intermediate. It must be the separately defined compound, not a formulated blend.
Does this code cover epoxy hardener blends that contain this amine?
No. Once the amine is mixed with other ingredients into a prepared hardener or formulated product, the goods are generally classified in Chapter 38 as a chemical preparation rather than under this single-chemical provision.
Where do similar cyclohexane diamines classify?
Other cyclanic polyamines that are not specifically named fall under residual lines within subheading 2921.30. Check the exact chemical name and CAS number against the HTS chemical appendix before defaulting to this code.
What is the HTS code 2921.30.05.00 used for?
HTS code 2921.30.05.00 is the harmonized tariff schedule code for 1,3-Bis(aminoethyl)cyclohexane. This code is used to classify and identify this product type for customs clearance, duty calculation, and trade statistics.
What is the Column 2 rate for HTS 2921.30.05.00?
The Column 2 rate is the tariff duty rate applicable to goods from countries that do not have normal trade relations with the United States. This rate is typically higher than Column 1 (Most Favored Nation) rates and is rarely used in modern trade due to most-favored-nation agreements.
Do I need a customs broker to import goods classified under HTS 2921.30.05.00?
While not always required, using a licensed customs broker is highly recommended for most imports. A customs broker can help ensure proper HTS classification, prepare customs documentation, pay duties correctly, and avoid delays or penalties. Your broker should be familiar with Chemical Products products.
Which countries receive special tariff rates for HTS 2921.30.05.00?
Multiple free trade agreements and trade preference programs provide reduced or free tariffs for eligible HTS classifications. Common programs include USMCA (Canada, Mexico), various bilateral FTAs (Korea, Australia, Singapore), GSP for developing countries, and AGOA for eligible African nations. Check the special rates section on this page.
How does HTS code 2921.30.05.00 affect my import costs?
The HTS code determines the applicable duty rate (either free or a percentage/specific amount), whether your product qualifies for trade agreement benefits, any quota restrictions, and special documentation requirements. Proper classification directly impacts your import expenses, so verify the correct code with your supplier or a customs professional.
