HS 292111 Acyclic monoamines and their derivatives; salts thereof
Quick Answer: HS Code 292111 covers acyclic monoamines and their derivatives, along with their salts. In plain language, this includes organic chemical compounds characterized by a single amino group attached to an open-chain (non-ring) carbon structure, such as methylamine or ethylamine, and their various chemical modifications or salt forms. These chemicals are fundamental building blocks in the pharmaceutical, agrochemical, and specialty chemical industries. For importers and exporters, understanding the duty rates is crucial. The UK applies a 6.00% ad valorem duty, while the EU TARIC system shows a 6.50% ad valorem rate. In the US, the Most Favored Nation (MFN) duty rate is 3.7% ad valorem, but significant preferential duty programs offer duty-free entry for goods originating from numerous countries, including Australia, Korea, and Singapore. Importers should verify eligibility for these programs to optimize costs. Additionally, a 25% Section 301 duty may apply to goods of Chinese origin.

How to Classify This HS Code?
What products does HS 292111 cover?
This subheading covers acyclic monoamines and their derivatives, as well as their salts. Specifically, it encompasses methylamine, diethylamine, and trimethylamine, which are primary, secondary, and tertiary acyclic monoamines, respectively. The WCO Harmonized System Nomenclature for Chapter 29, Heading 2921, defines amines as organic compounds containing one or more amino groups (-NH2, -NHR, or -NR2). Subheading 2921.11 specifically targets those that are acyclic (open-chain structure) and contain only one amino group (monoamines). This includes their halogenated, sulfonated, nitrated, or nitrosated derivatives, provided the essential character remains that of an amine. For instance, the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC system both align with this definition, classifying these specific chemical compounds under 2921.11.
What falls outside HS 292111?
The following products are excluded from HS 292111: acyclic diamines and polyamines, which are classified under other subheadings of 2921, such as 2921.21 for ethylenediamine. Cyclic monoamines, such as aniline (a primary aromatic amine), are also excluded and are classified under 2921.41. Amino-alcohols, amino-phenols, amino-ketones, and amino-acids are specifically excluded by the Chapter 29 legal notes and are classified in their respective headings (e.g., amino-alcohols in 2922, amino-acids in 2922.41). For example, ethanolamine, despite being an acyclic compound with an amine group, is an amino-alcohol and therefore falls under 2922.11, not 2921.11, due to the presence of a hydroxyl group.
What are common classification mistakes for HS 292111?
A common error is misclassifying compounds that contain both an amine group and another functional group, such as a hydroxyl or carboxyl group, under 2921.11. According to Chapter 29, Note 1(e), compounds containing more than one kind of oxygen-function or other specified functions are classified in the heading which occurs last in numerical order among those which equally merit consideration. Therefore, an amino-alcohol like methylaminoethanol, despite being an acyclic monoamine derivative, is classified under Heading 2922 as an amino-alcohol, not 2921.11. Another frequent mistake involves confusing acyclic monoamines with cyclic amines or polyamines, which have distinct subheadings within Heading 2921 or other headings entirely, leading to incorrect duty rates and compliance issues. Adherence to General Interpretative Rule (GRI) 1, which prioritizes the terms of the headings and any relative section or chapter notes, is crucial here.
How should importers classify products under HS 292111?
The correct procedure for classifying products under HS 292111 involves a systematic review of the chemical structure and functional groups. Importers and customs brokers must first confirm the compound is an amine and then verify it is acyclic and contains only one amino group. Crucially, they must also ensure the compound does not possess other functional groups that would direct its classification to a different heading, such as hydroxyl (amino-alcohols), carboxyl (amino-acids), or ketone (amino-ketones) groups, as per Chapter 29 legal notes. Consulting the WCO Explanatory Notes for Heading 2921 is highly recommended for detailed guidance. Furthermore, obtaining a Certificate of Analysis or a Safety Data Sheet (SDS) from the manufacturer, which clearly states the chemical name and CAS number, can significantly aid in accurate classification, ensuring compliance with USITC HTS, EU TARIC, or UK Trade Tariff regulations and avoiding potential penalties.

FAQ
What is the Most Favored Nation (MFN) import duty rate for goods classified under HS 2921.11 in the United States?
For goods classified under Harmonized System (HS) subheading 2921.11 ('Methylamine, ethylamine and their derivatives; salts thereof'), the Most Favored Nation (MFN) duty rate in the United States, as per the Harmonized Tariff Schedule of the United States (HTSUS), is 6.5% ad valorem. This rate applies to imports from countries that do not have a specific trade agreement or other preferential program with the U.S. or do not qualify for such programs.
Which trade agreements offer preferential duty treatment for HS 2921.11, and what are the associated rates?
Several U.S. Free Trade Agreements (FTAs) and preferential programs offer reduced or duty-free treatment for HS 2921.11, provided the goods meet the respective Rules of Origin. For example, imports from countries such as 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 qualify for a 'Free' duty rate under their respective FTAs. Importers must ensure they have the proper documentation, such as a Certificate of Origin, to claim these preferential rates. Consult the HTSUS General Notes and specific FTA texts for detailed rules of origin.
What are the key classification criteria for products under HS 2921.11?
HS 2921.11 specifically covers 'Acyclic monoamines and their derivatives; salts thereof,' with a focus on methylamine and ethylamine. The primary classification criteria revolve around the chemical structure: the presence of a single amino group (-NH2) attached to an acyclic (non-ring) carbon chain. Derivatives, such as N-methylmethylamine, and their corresponding salts (e.g., methylamine hydrochloride) are also included. It is crucial to distinguish these from polyamines, cyclic amines, or amino-alcohols, which fall under different subheadings. Chemical analysis and detailed product specifications are often necessary to confirm accurate classification.
Are there any specific documentation requirements for importing HS 2921.11, beyond standard customs entry documents?
Beyond standard customs entry documentation (e.g., commercial invoice, packing list, bill of lading/air waybill), importers of chemical products under HS 2921.11 should be prepared to provide a Safety Data Sheet (SDS) and a Certificate of Analysis (CoA) if requested by customs authorities. These documents verify the chemical identity, purity, and safety characteristics of the product. If claiming preferential duty rates under a Free Trade Agreement, a valid Certificate of Origin (or equivalent declaration) is mandatory to substantiate the claim. For certain applications or end-uses, additional regulatory approvals or permits from agencies like the Environmental Protection Agency (EPA) or Food and Drug Administration (FDA) might be required, though this is less common for basic amines unless they are part of a regulated product.
How do duty rates for HS 2921.11 compare in other major customs territories, such as the EU or UK?
Duty rates for HS 2921.11 vary by customs territory. In the European Union (EU), the Common Customs Tariff (TARIC) generally applies an MFN duty rate of 6.00% ad valorem for 'Methylamine, ethylamine and their derivatives; salts thereof.' Similarly, the UK Global Tariff (UKGT) also applies a 6.00% ad valorem MFN duty rate for this subheading. Both the EU and UK have extensive networks of preferential trade agreements that can reduce this rate to 0% (duty-free) for qualifying goods originating from partner countries. Importers should consult the specific EU TARIC database or the UK Trade Tariff for the most current and applicable rates, including any temporary suspensions or quotas.
