HS 292129 Other
Quick Answer: HS code 2921.29, "Other," encompasses acyclic polyamines and their derivatives not elsewhere specified within Chapter 29. This broad residual category covers various organic chemical compounds, including diamines and polyamines with diverse industrial applications, such as in polymer production, pharmaceuticals, and agrochemicals. Importers and exporters should note the varying duty rates: the UK and EU generally apply a 6.00% ad valorem duty. In contrast, the US rates range from 6.5% ad valorem to Free under various preferential trade agreements (e.g., A, AU, CL, KR), but can be as high as 30.5% for specific subheadings. Careful classification to the 8-digit or 10-digit level is crucial to determine the exact duty rate and leverage potential free trade agreement benefits, avoiding costly misclassifications.

How to Classify This HS Code?
What products does HS 292129 cover?
This subheading covers acyclic polyamines and their derivatives, specifically those not elsewhere specified within subheading 2921.21 (ethylenediamine and its salts) or 2921.22 (hexamethylenediamine and its salts). As per the Harmonized System Nomenclature, Chapter 29, Heading 2921 encompasses "Amine-function compounds." Subheading 2921.29 acts as a residual category for other acyclic polyamines, meaning compounds containing more than one amine (-NH2, -NH-, or -N-) functional group within an open-chain carbon structure, provided they are not specifically enumerated in the preceding subheadings. Examples include diethylenetriamine (DETA) and triethylenetetramine (TETA), which are crucial intermediates in various industrial applications, as defined by the USITC Harmonized Tariff Schedule and EU TARIC.
What falls outside HS 292129?
The following products are excluded from HS 292129: acyclic monoamines and their derivatives, which are classified under HS 2921.11 through 2921.19. Additionally, cyclic polyamines, such as piperazine, are excluded and fall under HS 2921.30 (Cyclic monoamines, their derivatives; cyclic polyamines, their derivatives). Ethylenediamine and its salts are specifically classified under HS 2921.21, while hexamethylenediamine and its salts are classified under HS 2921.22. Furthermore, compounds where the amine function is merely a side-chain to a more specific chemical function (e.g., amino-alcohols, amino-acids) would be classified according to their principal function elsewhere in Chapter 29 or other chapters, as per the General Interpretive Rules (GRI).
What are common classification mistakes for HS 292129?
A common error is misclassifying acyclic monoamines or cyclic polyamines into HS 292129, failing to recognize the specific scope of "polyamines" and "acyclic" within the heading. Importers sometimes overlook the explicit enumeration of ethylenediamine (2921.21) and hexamethylenediamine (2921.22), incorrectly placing them in the "other" category. Another frequent mistake involves compounds that contain an amine group but whose primary function or structure dictates classification elsewhere, such as amino-alcohols (HS 2922) or amino-acids (HS 2922). Proper application of GRI 1, which states that classification shall be determined according to the terms of the headings and any relative section or chapter notes, is crucial to avoid these errors.
How should importers classify products under HS 292129?
The correct procedure for classifying products under HS 292129 involves a systematic review of the chemical structure and functional groups. Importers and customs brokers must first confirm the compound is an amine-function compound (Heading 2921). Next, verify that it is an "acyclic" compound (open-chain structure) and contains "polyamines" (more than one amine group). Crucially, confirm that the specific polyamine is not ethylenediamine or its salts (2921.21) or hexamethylenediamine or its salts (2921.22). If these conditions are met, and no other more specific heading or subheading in Chapter 29 applies (e.g., amino-alcohols), then HS 292129 is the appropriate classification. Consulting the WCO Explanatory Notes for Chapter 29 and obtaining a chemical analysis or safety data sheet (SDS) for complex compounds is highly recommended to ensure accuracy.

FAQ
What is the Most Favored Nation (MFN) import duty rate for products classified under HS 2921.29?
For products classified under Harmonized System (HS) subheading 2921.29, which covers 'Acyclic amines and their derivatives; salts thereof: Cyclanic, cyclenic or cycloterpenic mono- or polyamines, and their derivatives; salts thereof: Other,' the Most Favored Nation (MFN) duty rate generally ranges. For example, the United States imposes an MFN duty rate of 6.5% ad valorem. Importers should consult the specific tariff schedule of the importing country (e.g., USITC Harmonized Tariff Schedule, EU TARIC, UK Trade Tariff) for the precise and current MFN rate applicable to their destination market.
Are there any preferential duty rates available for HS 2921.29 under common trade agreements?
Yes, preferential duty rates are frequently available for HS 2921.29 under various free trade agreements (FTAs) and special programs. For instance, imports into the United States from countries like Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Jordan (JO), Korea (KR), Morocco (MA), Oman (OM), Panama (PA), Peru (PE), and Singapore (SG) may be eligible for a 'Free' (0%) duty rate under respective FTAs. Similarly, countries participating in programs like the Generalized System of Preferences (GSP) might also qualify for reduced or duty-free entry. Importers must ensure they meet the Rules of Origin requirements of the specific trade agreement to claim preferential treatment and provide proper documentation, such as a certificate of origin.
What are the key classification criteria for determining if a product falls under HS 2921.29?
HS 2921.29 is a residual subheading within Chapter 29, specifically for 'Cyclanic, cyclenic or cycloterpenic mono- or polyamines, and their derivatives; salts thereof: Other.' The primary classification criteria involve verifying the chemical structure of the compound. It must be an amine (containing at least one nitrogen atom bonded to a carbon atom) that is cyclanic, cyclenic, or cycloterpenic. The 'Other' designation means it does not fall into the more specific subheadings within 2921.21 or 2921.22. Importers should have detailed chemical specifications, including CAS numbers and chemical names, to ensure accurate classification. Reference to the Explanatory Notes of the Harmonized System (WCO) for Chapter 29 provides further guidance on the scope of amines and their derivatives.
What documentation is typically required for importing chemicals classified under HS 2921.29?
Importing chemicals under HS 2921.29 typically requires standard customs documentation, including a commercial invoice, packing list, and bill of lading or air waybill. Additionally, due to the chemical nature of the goods, specific regulatory documentation is often necessary. This may include a Safety Data Sheet (SDS) or Material Safety Data Sheet (MSDS), a Certificate of Analysis (CoA), and potentially import licenses or permits depending on the specific chemical and the importing country's regulations (e.g., chemical control laws, environmental regulations). For claiming preferential duty rates, a valid Certificate of Origin is mandatory. Customs brokers should verify all required documentation with the relevant customs authorities prior to shipment.
Could a product classified under HS 2921.29 be subject to additional duties, such as anti-dumping or countervailing duties?
Yes, like many chemical products, goods classified under HS 2921.29 could potentially be subject to additional duties such as anti-dumping duties (ADD) or countervailing duties (CVD). These duties are imposed by importing countries to counteract unfair trade practices, such as dumping (selling goods below fair market value) or subsidies provided by foreign governments. Importers must regularly check the trade remedies databases of the importing country (e.g., U.S. Department of Commerce, EU Commission) to determine if any specific product originating from certain countries is subject to ADD or CVD. Failure to account for these duties can result in significant financial penalties and delays.
