How to Classify This HS Code?
What products does HS 292159 cover?
This subheading covers "Other" amino-alcohol-phenols, amino-acid-phenols and other amino compounds with oxygen function, specifically those not elsewhere specified within the broader category of amino-compounds of Heading 2921, which encompasses oxygen-function amino-compounds. According to the Harmonized System Nomenclature by the World Customs Organization (WCO), and reflected in national tariffs like the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC, this residual subheading captures a diverse range of organic chemical compounds possessing both an amino functional group and at least one oxygen-containing functional group (e.g., hydroxyl, ether, aldehyde, ketone, carboxyl) that are not more specifically provided for in subheadings 2921.51 through 2921.58. Examples might include complex amino-alcohols or amino-phenols that do not fit the specific chemical structures defined in other subheadings.
What falls outside HS 292159?
The following products are excluded from HS 292159 and are classified elsewhere due to more specific provisions within Heading 2921 or other chapters. For instance, amino-naphthols and other amino-phenols (other than those containing more than one type of oxygen function, or those with a nitrogen atom directly attached to a benzene ring) are specifically classified under 2921.42. Similarly, compounds like anilines, toluidines, and xylidines, which are aromatic monoamines without oxygen function, fall under 2921.41. Furthermore, amino-alcohols, other than those containing two or more types of oxygen function, are classified in 2921.49. Products that are derivatives of amino-acids, such as peptides or proteins, are generally classified in Chapter 29 or 35, depending on their complexity and function, and are distinct from the simpler amino compounds covered here.
What are common classification mistakes for HS 292159?
A common error is misclassifying specific amino-oxygen compounds into HS 292159 when a more specific subheading exists within Heading 2921. Importers often overlook the detailed chemical structure requirements of subheadings 2921.51 through 2921.58, leading to incorrect residual classification. For example, compounds that are clearly amino-naphthols or other amino-phenols (e.g., aminophenols with only one type of oxygen function) should be classified under 2921.42, not 2921.59. Another frequent mistake involves failing to correctly identify all functional groups present in a complex organic molecule, which can lead to misapplication of General Interpretative Rule (GRI) 1, where the legal text of the subheading is paramount, or GRI 6, which extends GRIs 1 to 5 to the subheading level. Thorough chemical analysis is crucial to avoid these errors.
How should importers classify products under HS 292159?
The correct procedure for classifying products under HS 292159 involves a systematic review of the product's chemical structure and functional groups. Importers and customs brokers must first identify if the compound is an amino-compound with an oxygen function. Next, they should meticulously examine the specific subheadings within Heading 2921 (e.g., 2921.51, 2921.52, etc.) to determine if the product fits a more specific description. Only if the compound does not meet the criteria for any other specific subheading within Heading 2921, and it is indeed an amino-compound with an oxygen function, should it be considered for classification under 292159. Consulting the WCO Explanatory Notes for Chapter 29 and obtaining a detailed Certificate of Analysis (CoA) for the chemical compound are essential steps to ensure accurate and compliant classification, minimizing the risk of penalties or delays.

FAQ
What is the Harmonized System (HS) classification for 'Other' acyclic polyamines, and what are the typical Most Favored Nation (MFN) duty rates?
HS code 2921.59 specifically covers 'Other' acyclic polyamines and their derivatives, which fall under Chapter 29 (Organic Chemicals) and Heading 2921 (Amine-function compounds). This 'Other' subheading is a residual category for acyclic polyamines not specifically enumerated in subheadings 2921.51 through 2921.59. MFN duty rates for HS 2921.59 can vary significantly by importing country. For instance, the United States (USITC) generally applies a duty rate of 6.5% ad valorem for products from non-preferential countries. The European Union (EU TARIC) often applies a duty rate of 6.5% ad valorem. The United Kingdom Global Tariff (UKGT) also typically applies a 6.5% ad valorem rate. However, some countries may offer duty-free treatment (0.00%) or apply specific rates such as 15.4¢/kg + 39.5% for certain origins or product types, depending on their national tariff schedules. Importers should consult the specific tariff schedule of the importing country for the most accurate and current MFN duty rate.
Are there any preferential duty rates or free trade agreements that impact imports under HS 2921.59?
Yes, preferential duty rates are frequently available for products classified under HS 2921.59, depending on the country of origin and applicable trade agreements. For example, under the United States-Mexico-Canada Agreement (USMCA), goods originating from Mexico or Canada may qualify for duty-free (0.00%) treatment when imported into the U.S., provided they meet the agreement's Rules of Origin. Similarly, the EU has numerous free trade agreements (FTAs) that could grant duty-free access or reduced rates for products from partner countries. The UK also has an extensive network of FTAs and preferential arrangements. Importers should verify if their specific product and country of origin qualify under agreements such as the Generalized System of Preferences (GSP), various bilateral FTAs, or regional agreements. Proper documentation, such as a Certificate of Origin, is essential to claim preferential treatment.
What are the key classification criteria for determining if a chemical falls under HS 2921.59 'Other' acyclic polyamines?
The primary classification criteria for HS 2921.59 revolve around the chemical structure and function. To be classified here, the chemical must be: 1. Acyclic: Meaning it does not contain a ring structure in its main carbon chain. 2. Polyamine: Indicating it contains two or more amine (-NH2, -NHR, -NR2) functional groups. 3. Derivative: It can also be a derivative of such a polyamine. 4. 'Other': Crucially, it must not be specifically provided for in subheadings 2921.51 (e.g., ethylenediamine, hexamethylenediamine) or 2921.59. The World Customs Organization (WCO) Explanatory Notes for Heading 2921 provide detailed guidance on the scope of amine-function compounds. Importers should have a precise chemical name, CAS number, and structural formula to ensure accurate classification, as misclassification can lead to penalties and delays.
What specific documentation is required for importing chemicals under HS 2921.59, beyond standard customs forms?
Beyond standard customs entry forms (e.g., CBP Form 7501 in the U.S., Single Administrative Document in the EU/UK), importers of chemicals under HS 2921.59 may require additional documentation. This often includes: 1. Safety Data Sheet (SDS): Essential for hazardous chemicals, providing information on properties, hazards, and safe handling. 2. Certificate of Analysis (CoA): Verifies the chemical composition, purity, and specifications of the imported product. 3. Commercial Invoice: Detailing the product, quantity, value, and terms of sale. 4. Packing List: Itemizing contents of each package. 5. Bill of Lading or Air Waybill: Transportation document. 6. Certificate of Origin: Required to claim preferential duty rates under FTAs. Depending on the specific chemical and importing country's regulations, permits or licenses from agencies like the Environmental Protection Agency (EPA) in the U.S. or REACH compliance documentation in the EU/UK might also be necessary, especially if the substance is new, regulated, or subject to specific chemical control laws.
