HS 291219 Other
Quick Answer: HS code 2912.19, "Other," covers acyclic aldehydes without other oxygen function, excluding methanal (formaldehyde) and ethanal (acetaldehyde). This residual category captures various straight-chain or branched-chain aldehydes not specifically enumerated elsewhere in subheading 2912.1. Importers and customs brokers should note the varying duty rates: the UK applies rates like 4.00% ad valorem, while the EU typically levies 5.50% ad valorem. The US tariff schedule shows a 4.8% ad valorem rate, with numerous Free (A,AU,BH,CL,CO,D,E,IL,JO,KR,MA,OM,P,PA,PE,S,SG) provisions under various trade agreements, but also a prohibitive 45% ad valorem rate for certain non-MFN origins. Precise classification within this "Other" category requires careful review of the chemical structure against specific subheadings to avoid misclassification and ensure accurate duty assessment.

How to Classify This HS Code?
What products does HS 291219 cover?
This subheading covers acyclic aldehydes, not containing other oxygen-functions, specifically those other than methanal (formaldehyde) and ethanal (acetaldehyde), which are classified under HS 2912.11 and 2912.12, respectively. Products falling into 2912.19 are typically straight-chain or branched-chain aldehydes without additional hydroxyl, ether, or ester groups, for instance. The WCO Harmonized System Explanatory Notes for Heading 2912 clarify that this group encompasses a wide range of simple acyclic aldehydes, such as propanal (propionaldehyde), butanal (butyraldehyde), pentanal (valeraldehyde), and hexanal, provided they do not possess other oxygen-containing functional groups that would lead to classification elsewhere in Chapter 29. Official definitions from the USITC Harmonized Tariff Schedule and EU TARIC confirm this scope, focusing on the absence of other oxygen-functions.
What falls outside HS 291219?
The following products are excluded from HS 291219: methanal (formaldehyde), which is specifically classified under HS 2912.11, and ethanal (acetaldehyde), classified under HS 2912.12. Furthermore, aldehydes containing other oxygen-functions, such as aldehyde-alcohols (e.g., hydroxycitronellal, HS 2912.42), aldehyde-ethers, aldehyde-phenols, and aldehyde-ketones, are excluded and fall into subheadings 2912.41 through 2912.49. For example, vanillin, an aldehyde-phenol, is classified under HS 2912.42. Cyclic aldehydes, whether aromatic or alicyclic, are also excluded and are classified under HS 2912.21 or 2912.29. Polymers of aldehydes, such as paraformaldehyde, are generally classified under Chapter 39 as plastics, not under Heading 2912, as they are no longer simple chemical compounds.
What are common classification mistakes for HS 291219?
A common error is misclassifying aldehydes with additional oxygen-functions, such as hydroxyl or ether groups, into HS 291219, when they properly belong in subheadings 2912.41 through 2912.49. Importers sometimes overlook the "not containing other oxygen-functions" criterion, leading to incorrect classification. For instance, classifying 3-hydroxybutanal (aldol) under 291219 instead of 2912.49 is a frequent mistake, as it contains an alcohol (hydroxyl) function. Another error involves misidentifying specific acyclic aldehydes like formaldehyde or acetaldehyde, which have their own dedicated subheadings (2912.11 and 2912.12, respectively), and incorrectly placing them into the "other" category of 291219. Adherence to General Interpretative Rule (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 291219?
The correct procedure for classifying products under HS 291219 involves a meticulous review of the chemical structure and functional groups present in the aldehyde. Importers and customs brokers must first confirm that the product is an acyclic aldehyde. Subsequently, it is essential to verify the absence of any other oxygen-containing functional groups (e.g., hydroxyl, ether, ester, ketone, carboxyl) in the molecule, as their presence would direct classification to other subheadings within Heading 2912 or even other chapters. Furthermore, confirm that the specific aldehyde is not methanal (formaldehyde) or ethanal (acetaldehyde), which have their own distinct subheadings. Consulting the WCO Harmonized System Explanatory Notes for Heading 2912 is highly recommended to clarify scope and exclusions. When in doubt, obtaining a binding ruling from the relevant customs authority (e.g., CBP in the US, national customs authorities in the EU) provides legal certainty.

FAQ
What are the typical Most Favored Nation (MFN) import duty rates for products classified under HS 2912.19, and how do preferential trade agreements impact these rates?
The Most Favored Nation (MFN) import duty rates for products classified under HS 2912.19 ('Other' acyclic aldehydes without other oxygen function) can vary significantly by importing country. For instance, common MFN rates observed in various jurisdictions include 4.0% ad valorem, 4.8% ad valorem, or 5.5% ad valorem. Some countries may apply a 0.0% MFN rate, while others, particularly those with protective tariffs, might impose rates as high as 45% ad valorem. Importers should consult the specific tariff schedule of the importing country (e.g., USITC Harmonized Tariff Schedule of the United States, EU TARIC, UK Trade Tariff). Under various Free Trade Agreements (FTAs) or Generalized System of Preferences (GSP) programs, goods originating from eligible countries may qualify for preferential duty treatment, often resulting in a 'Free' (0.0% ad valorem) rate. Examples of countries whose products might receive preferential treatment include Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Jordan (JO), Korea (KR), Morocco (MA), Oman (OM), Panama (PA), Peru (PE), Singapore (SG), and others depending on the specific agreement with the importing nation. It is crucial to verify origin criteria and provide appropriate documentation (e.g., Certificate of Origin) to claim preferential rates.
What are the key classification criteria for determining if a product falls under HS 2912.19, specifically distinguishing it from other aldehyde subheadings?
HS 2912.19 covers 'Other' acyclic aldehydes without other oxygen function. The primary classification criteria revolve around the chemical structure of the aldehyde. To be classified under this subheading, the product must be: 1) An aldehyde: containing at least one -CHO group. 2) Acyclic: meaning its carbon chain does not form a ring structure. 3) Without other oxygen function: This is a critical differentiator. It means the molecule should not contain other oxygen-bearing functional groups such as alcohols (-OH), ethers (-O-), carboxylic acids (-COOH), esters (-COO-), or ketones (>C=O) in addition to the aldehyde group. If it possesses such additional oxygen functions, it would typically fall under HS 2912.20 ('Cyclic aldehydes without other oxygen function') or HS 2912.4x ('Aldehyde-alcohols, aldehyde-ethers, aldehyde-phenols and other aldehydes with other oxygen function'). For example, formaldehyde (methanal) is classified under 2912.11, and ethanal (acetaldehyde) under 2912.12. HS 2912.19 is a residual category for acyclic aldehydes without other oxygen function not specifically provided for in 2912.11 or 2912.12. Importers should refer to the Explanatory Notes to Chapter 29 of the Harmonized System for detailed chemical definitions and examples.
What specific documentation is required for the importation of goods classified under HS 2912.19, beyond standard customs paperwork?
Beyond standard customs documentation such as the commercial invoice, packing list, and bill of lading/air waybill, the importation of chemical products under HS 2912.19 may require additional specific documentation due to regulatory controls. Key documents often include: 1) Safety Data Sheet (SDS): Essential for identifying the chemical composition, hazards, and safe handling procedures. This is often required by health, safety, and environmental agencies. 2) Certificate of Analysis (CoA): Provides detailed information on the purity, concentration, and physical/chemical properties of the specific batch, ensuring it meets specifications. 3) Certificate of Origin: Crucial for claiming preferential duty rates under trade agreements. This document, often issued by a chamber of commerce or the exporter, attests to the country where the goods were manufactured or processed. 4) Import Licenses or Permits: Depending on the specific aldehyde and its end-use, certain countries may require import licenses or permits from regulatory bodies (e.g., environmental protection agencies, chemical control authorities) if the substance is controlled or restricted. Importers should verify specific national requirements with their customs broker or the relevant government agencies in the importing country.
Are there any common trade agreements that specifically offer duty-free access or reduced rates for products under HS 2912.19, and what are the general conditions for eligibility?
Yes, numerous trade agreements offer duty-free access or reduced rates for products classified under HS 2912.19, provided they meet the respective Rules of Origin (ROO). For instance, under the United States-Mexico-Canada Agreement (USMCA), goods originating in Mexico or Canada would generally qualify for duty-free entry into the U.S. if they meet the ROO. Similarly, the EU's network of Free Trade Agreements (e.g., with Korea, Japan, Canada, UK) typically provides preferential treatment. The UK's independent trade agreements (e.g., with Australia, Japan) also offer similar benefits. General conditions for eligibility typically include: 1) Direct Consignment: The goods must be shipped directly from the exporting country to the importing country, though transshipment with proper documentation is often allowed. 2) Rules of Origin: This is the most critical condition. The product must originate in a party to the agreement, meaning it must be wholly obtained or undergo sufficient transformation in that country. For chemicals like those in HS 2912.19, this often involves a change in tariff classification at the 4-digit or 6-digit level, or meeting a regional value content (RVC) threshold. 3) Proof of Origin: A valid Certificate of Origin (e.g., EUR.1, GSP Form A, USMCA Certification of Origin) or a declaration of origin by the exporter is required at the time of importation to claim the preferential rate. Importers must ensure their suppliers can provide the necessary documentation and that the goods meet the specific ROO of the applicable agreement.
