HS 291529 Other
Quick Answer: HS 2915.29, "Other," covers a diverse range of saturated acyclic monocarboxylic acids and their anhydrides, halides, peroxides, peroxyacids, and their derivatives, specifically those not classified under 2915.21 (acetic acid) or 2915.22 (sodium acetate). This broad residual category includes various organic chemicals crucial for pharmaceuticals, plastics, and chemical synthesis. Importers and exporters should note the varying duty rates: the UK applies 0.00%, the EU has a 5.50% ad valorem duty, while the US exhibits a range from Free to 25% (e.g., for certain products from non-MFN countries) or 3.7% ad valorem, depending on the specific chemical and country of origin. Due to the "Other" designation, precise chemical identification is paramount for accurate classification and duty assessment.

How to Classify This HS Code?
What products does HS 291529 cover?
This subheading covers saturated acyclic monocarboxylic acids and their anhydrides, halides, peroxides, peroxyacids, and their halogenated, sulphonated, nitrated, or nitrosated derivatives, specifically those that are not formic acid (2915.1X) or acetic acid (2915.21). According to the Harmonized System Explanatory Notes for Heading 2915, this residual subheading captures a range of saturated acyclic monocarboxylic acids with more than two carbon atoms, such as propionic acid, butyric acid, valeric acid, and their various derivatives, provided they are not specifically enumerated elsewhere in the HS nomenclature. This aligns with the definitions found in the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC system for this specific eight-digit classification.
What falls outside HS 291529?
The following products are excluded from HS 291529: formic acid, its salts, and esters, which are classified under subheadings 2915.11 through 2915.13. Similarly, acetic acid and its salts and esters are specifically provided for under subheadings 2915.21 through 2915.24. Furthermore, unsaturated acyclic monocarboxylic acids, such as acrylic acid, are classified under Heading 2916, as they do not meet the "saturated" criterion of Heading 2915. Complex carboxylic acid derivatives, such as those with additional functional groups that confer a more specific character, might be classified under other headings in Chapter 29 or even Chapter 38 if they are mixtures or preparations, rather than pure chemical compounds.
What are common classification mistakes for HS 291529?
A common error is misclassifying propionic acid or butyric acid derivatives under the more specific subheadings for acetic acid (2915.21) or formic acid (2915.1X), due to a lack of precise chemical identification. Importers sometimes overlook the "other" designation and fail to correctly identify the specific carbon chain length or saturation of the acid. Another frequent mistake involves classifying mixtures containing these acids under 291529, when in fact, if the mixture constitutes a preparation or has a specific end-use function, it might be more appropriately classified under Chapter 38, according to General Interpretative Rule (GRI) 3(b). Accurate chemical analysis and understanding of the WCO Explanatory Notes are crucial to avoid these pitfalls.
How should importers classify products under HS 291529?
The correct procedure for classifying products under HS 291529 involves a meticulous review of the chemical composition and structure of the substance. Importers and customs brokers should first confirm that the product is a saturated acyclic monocarboxylic acid or one of its specified derivatives (anhydrides, halides, peroxides, peroxyacids, or halogenated, sulphonated, nitrated, or nitrosated derivatives). Next, they must ensure it is not formic acid or acetic acid, which have their own dedicated subheadings. Consulting the WCO Harmonized System Explanatory Notes for Heading 2915 is essential to understand the scope of "other" and to verify that no more specific heading or subheading applies, applying GRI 1 and GRI 6 for accurate eight-digit classification. Obtaining a Certificate of Analysis (CoA) from the manufacturer detailing the chemical name, CAS number, and purity is highly recommended to support the classification decision.

FAQ
What is the Most Favored Nation (MFN) import duty rate for HS 2915.29 in the United States, and are there any common preferential rates?
For products classified under Harmonized System (HS) subheading 2915.29, 'Other' (referring to other acetic acid esters), the Most Favored Nation (MFN) duty rate in the United States, as per the Harmonized Tariff Schedule of the United States (HTSUS), is 3.7% ad valorem. Importers should also investigate potential preferential duty rates available under various Free Trade Agreements (FTAs) or special programs. For example, goods originating from countries party to agreements like USMCA (formerly NAFTA), CAFTA-DR, or GSP (Generalized System of Preferences) may qualify for a 'Free' duty rate, provided all rules of origin and other program requirements are met. It is crucial to verify the specific country of origin and applicable trade agreement provisions using the latest HTSUS and relevant trade agreement texts.
What are the key classification criteria for determining if a product falls under HS 2915.29 versus other subheadings for acetic acid esters?
HS subheading 2915.29 is a residual 'Other' category within heading 2915, which covers 'Saturated acyclic monocarboxylic acids and their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulfonated, nitrated or nitrosated derivatives.' Specifically, 2915.29 applies to 'Esters of acetic acid' that are not specifically provided for in subheadings 2915.21 ('Ethyl acetate'), 2915.23 ('n-Butyl acetate'), or 2915.24 ('Isobutyl acetate'). The primary classification criterion is the specific ester compound of acetic acid. If the chemical name of the ester (e.g., propyl acetate, pentyl acetate) is not explicitly listed in 2915.21, 2915.23, or 2915.24, and it is indeed an ester of acetic acid, then it defaults to 2915.29. Chemical analysis and precise nomenclature are essential for accurate classification, adhering to the General Rules of Interpretation (GRIs) and relevant WCO Explanatory Notes.
What documentation is typically required for importing goods classified under HS 2915.29, especially to claim preferential duty rates?
Standard import documentation for HS 2915.29 includes a commercial invoice, packing list, and bill of lading or air waybill. To claim preferential duty rates under a Free Trade Agreement (FTA) or special program, additional documentation is critical. This typically involves a Certificate of Origin or a declaration of origin, which attests that the goods meet the specific rules of origin requirements of the respective agreement (e.g., USMCA Certificate of Origin, EUR.1 movement certificate for EU imports). Importers must retain all supporting records, such as production records, material costs, and manufacturing processes, for a minimum of five years (or as required by the importing country's regulations) to substantiate origin claims, as customs authorities may request these during verification audits. Failure to provide adequate documentation can result in denial of preferential treatment and potential penalties.
Are there any specific import restrictions or regulatory requirements for chemical products under HS 2915.29 in major markets like the EU or UK?
Yes, chemical products, including those under HS 2915.29, are subject to various regulatory requirements beyond customs duties in major markets. In the European Union (EU) and the United Kingdom (UK), importers must comply with REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulations. This means that substances imported into the EU/UK in quantities of one tonne or more per year must be registered with the European Chemicals Agency (ECHA) or the UK REACH authority, respectively, unless an exemption applies. Importers are responsible for ensuring that the imported chemicals comply with all relevant safety data sheet (SDS) requirements, labeling regulations (e.g., CLP Regulation in the EU), and any specific restrictions on use or concentration for particular substances. It is advisable to consult the ECHA website (for EU) or the UK Health and Safety Executive (HSE) website (for UK) for the latest regulatory guidance applicable to the specific chemical compound being imported.
How do duty rates for HS 2915.29 compare across different major trading blocs, for example, the EU, UK, and the US?
The MFN duty rates for HS 2915.29 can vary significantly across major trading blocs. In the United States, as previously mentioned, the MFN duty rate is 3.7% ad valorem. For imports into the European Union (EU), according to the EU TARIC database, the MFN duty rate for HS 2915.29.00.00 is typically 5.50% ad valorem. Similarly, for imports into the United Kingdom (UK), the UK Global Tariff (UKGT) generally aligns with the EU's previous MFN rate, setting the MFN duty rate for HS 2915.29.00.00 at 5.50% ad valorem. However, all these regions offer preferential rates (often 'Free') under various trade agreements. For instance, goods originating from countries with which the EU or UK have FTAs (e.g., Japan, Canada, South Korea) may enter duty-free, provided origin rules are met. Importers must always consult the specific tariff schedule of the importing country (e.g., HTSUS, EU TARIC, UK Trade Tariff) for the most current and accurate rates applicable to their specific country of origin.
