HS 292231 Amino-aldehydes, amino-ketones and amino-quinones, other than those containing more than one kind of oxygen function; salts thereof
Quick Answer: HS Code 2922.31 specifically covers amino-aldehydes, amino-ketones, and amino-quinones, provided they do not contain more than one type of oxygen function (e.g., only an aldehyde group and an amine, not an aldehyde and a hydroxyl group). This also includes their respective salts. These are organic chemical compounds characterized by both an amine group and a carbonyl group (aldehyde, ketone, or quinone). For importers and exporters, understanding the duty landscape is crucial. In the UK and EU, the standard duty rate for products classified under 2922.31 is 0.00% ad valorem, indicating duty-free entry. Conversely, the United States applies a more complex duty structure, with a sample rate of "Free" for certain origins, but also potentially 15.4¢/kg + 50% ad valorem for others, highlighting the importance of origin and specific product details. Importers should verify the exact duty rate based on the country of origin and specific product characteristics using the USITC Harmonized Tariff Schedule.

How to Classify This HS Code?
What products does HS 292231 cover?
This subheading covers amino-aldehydes, amino-ketones, and amino-quinones, specifically those that do not contain more than one kind of oxygen function, as well as their respective salts. This precise scope is defined by the Harmonized System Nomenclature, as interpreted by the World Customs Organization (WCO), and reflected in national tariffs such as the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC. A key characteristic for inclusion is the presence of an amino group and an aldehyde, ketone, or quinone function, without additional distinct oxygen-containing functional groups like hydroxyls (alcohols) or carboxyls (acids) within the same molecule, beyond the primary aldehyde, ketone, or quinone function.
What falls outside HS 292231?
The following products are excluded from HS 292231: compounds containing more than one kind of oxygen function, for example, an amino-ketone that also possesses a hydroxyl group, which would typically be classified in other subheadings within Chapter 29, potentially 2922. For instance, amino alcohols (containing both amino and hydroxyl groups) are classified under 2922.19, and amino acids (containing both amino and carboxyl groups) fall under 2922.4. Additionally, cyclic amides, such as lactams, are specifically excluded from Heading 2922 by Note 5 to Chapter 29, and are generally classified under Heading 2933, even if they possess an amino group elsewhere in the molecule.
What are common classification mistakes for HS 292231?
A common error is misinterpreting the phrase "other than those containing more than one kind of oxygen function," leading to the incorrect inclusion of compounds with multiple distinct oxygen-containing functional groups. Importers often overlook the specific exclusion of compounds that, for example, combine an amino-ketone structure with an additional alcohol or carboxylic acid group, which would necessitate classification elsewhere in Chapter 29. Another frequent mistake involves confusing amino-ketones with cyclic amides (lactams), which are explicitly excluded from Heading 2922 by Chapter Note 5 and should be classified under Heading 2933, emphasizing the importance of applying General Interpretative Rule (GRI) 1 and relevant Chapter Notes precisely.
How should importers classify products under HS 292231?
The correct procedure for classifying products under HS 292231 involves a meticulous review of the chemical structure to confirm the presence of an amino group and either an aldehyde, ketone, or quinone function. Importers and customs brokers must rigorously verify that the compound does not contain any other distinct type of oxygen function beyond the primary aldehyde, ketone, or quinone group, as per the WCO Explanatory Notes and national tariff schedules like the USITC HTS and EU TARIC. It is crucial to consult chemical specifications, Certificates of Analysis, and Safety Data Sheets to identify all functional groups present, ensuring strict adherence to GRI 1 and the specific wording of the subheading and relevant Chapter Notes to avoid misclassification.

FAQ
What are the Most Favored Nation (MFN) duty rates for products classified under HS 2922.31 in key markets?
The MFN duty rates for HS 2922.31, which covers 'Amino-aldehydes, amino-ketones and amino-quinones, other than those containing more than one kind of oxygen function; salts thereof,' vary by importing country. For example, as per the USITC Harmonized Tariff Schedule (HTS) under subheading 2922.31.00, the MFN (General) duty rate for imports into the United States is 3.5% ad valorem. In contrast, the EU TARIC system (e.g., heading 2922 31 00) typically applies a duty rate of 6.5% ad valorem for MFN imports. Importers should always consult the specific tariff schedule of the destination country for the most current and accurate rates.
What are the primary classification criteria for distinguishing products under HS 2922.31 from other chemical classifications?
The key classification criterion for HS 2922.31, as defined by the World Customs Organization (WCO) Harmonized System Explanatory Notes, is the presence of an amino function combined with an aldehyde, ketone, or quinone function, without containing more than one kind of oxygen function. This means the compound must primarily feature these specific nitrogen and oxygen functional groups. If the compound contains, for instance, both a ketone and an ether function, it would generally be excluded from 2922.31 and classified elsewhere (e.g., Chapter 29, Subchapter IX for compounds with other oxygen functions). Importers and customs brokers should meticulously review the chemical structure and functional groups of the product to ensure accurate classification.
Which common trade agreements might offer preferential duty rates for HS 2922.31, and what documentation is typically required to claim them?
Preferential duty rates for HS 2922.31 can be available under various free trade agreements (FTAs) depending on the origin and destination countries. For instance, goods originating from countries party to agreements like the USMCA (United States-Mexico-Canada Agreement), EU-Japan EPA, or UK-EU Trade and Cooperation Agreement might qualify for reduced or zero duties. To claim preferential treatment, importers typically need to provide a Certificate of Origin (e.g., USMCA Certificate of Origin, EUR.1 movement certificate for EU agreements, or a statement on origin) that substantiates the product's originating status according to the specific rules of origin of the respective agreement. Failure to provide correct documentation will result in the application of the MFN duty rate.
Are there any specific documentation requirements or regulatory considerations for importing chemicals under HS 2922.31, beyond standard customs declarations?
Beyond standard customs declarations (e.g., commercial invoice, packing list, bill of lading), the import of chemicals under HS 2922.31 may be subject to additional regulatory requirements depending on the specific chemical compound and the importing country. For example, a Safety Data Sheet (SDS) is almost universally required for chemical imports to provide information on hazards, handling, and emergency procedures. In some jurisdictions, specific chemicals may require import licenses, permits, or registration under chemical control laws (e.g., TSCA in the US, REACH in the EU, or UK REACH). Importers should verify with the relevant national chemical regulatory authorities and customs agencies to ensure full compliance prior to shipment.
