HS 291719 Other
Quick Answer: HS code 2917.19, "Other," encompasses a diverse range of acyclic carboxylic acids and their anhydrides, halides, peroxides, and peroxyacids, specifically those not classified under more specific subheadings within 2917.1. This includes various saturated acyclic monocarboxylic acids and their derivatives. Duty rates vary significantly by jurisdiction and specific product. For example, the UK Trade Tariff shows rates such as 6.00% and 0.00%, reflecting product-specific classifications. The EU TARIC system similarly presents rates like 6.50% and 0.00%. In the US, the general Most Favored Nation (MFN) rate can be 6.5% ad valorem, or even a compound rate like 15.4¢/kg + 45%, with many products eligible for "Free" duty under various preferential trade agreements (e.g., A, AU, CL, KR). Importers and customs brokers must meticulously classify products to the 8-digit (or 10-digit in some jurisdictions) level to determine the precise duty rate and leverage applicable trade preferences.

How to Classify This HS Code?
What products does HS 291719 cover?
This subheading covers acyclic polycarboxylic acids, their anhydrides, halides, peroxides, peroxyacids, and their halogenated, sulphonated, nitrated, or nitrosated derivatives, that are not specifically provided for in other subheadings under Heading 2917. This includes a broad range of organic chemical compounds characterized by having more than one carboxyl group (-COOH) in an open-chain structure, provided they are not malonic acid, succinic acid, glutaric acid, adipic acid, azelaic acid, sebacic acid, maleic acid, or phthalic acid, their anhydrides or derivatives. The WCO Harmonized System Explanatory Notes for Chapter 29 and the USITC Harmonized Tariff Schedule (HTS) and EU TARIC provide the foundational scope for this "other" category, encompassing various less common or specialized acyclic polycarboxylic acids and their specified derivatives.
What falls outside HS 291719?
The following products are excluded from HS 291719: specific acyclic polycarboxylic acids and their derivatives enumerated in other subheadings of Heading 2917. For instance, malonic acid and its salts are classified under 291711, succinic acid under 291712, azelaic acid and sebacic acid under 291713, and maleic anhydride under 291714. Furthermore, cyclic polycarboxylic acids, such as phthalic acid (291739), are explicitly excluded as they fall under different structural categories within Heading 2917 or other headings in Chapter 29. Products that are not chemically defined pure compounds, or mixtures, would also typically be excluded, potentially falling into Chapter 38 or other relevant chapters based on their composition and intended use.
What are common classification mistakes for HS 291719?
A common error is misclassifying specific acyclic polycarboxylic acids or their anhydrides under 291719 when they have a dedicated subheading. For example, classifying maleic anhydride (291714) or adipic acid (291712) under "other" due to a lack of detailed chemical analysis or an incomplete review of the tariff schedule. Another frequent mistake involves overlooking the "acyclic" requirement, leading to the incorrect inclusion of cyclic polycarboxylic acids. Importers sometimes also fail to apply General Interpretative Rule (GRI) 1, which mandates classification according to the terms of the headings and any relative section or chapter notes, before resorting to "other" categories. Proper identification of the chemical structure and comparison against the specific provisions of Heading 2917 is crucial to avoid these errors.
How should importers classify products under HS 291719?
The correct procedure for classifying products under HS 291719 involves a systematic approach. First, importers and customs brokers must precisely identify the chemical name and structure of the substance to confirm it is an acyclic polycarboxylic acid or one of its specified derivatives (anhydrides, halides, peroxides, peroxyacids, or halogenated, sulphonated, nitrated, or nitrosated derivatives). Second, they must meticulously review all other subheadings within Heading 2917 (e.g., 291711, 291712, 291713, 291714) to ensure the product is not specifically enumerated elsewhere. Only if the product meets the general description of Heading 2917 and is not covered by a more specific subheading within the acyclic polycarboxylic acid group should it be classified under 291719. Consulting the WCO Explanatory Notes, USITC HTS, and EU TARIC is essential for accurate determination, and obtaining a chemical analysis report (Certificate of Analysis) is highly recommended.

FAQ
What is the general import duty rate for products classified under HS 2917.19 ('Other' acyclic monocarboxylic acids, their anhydrides, halides, peroxides, peroxyacids, and their derivatives) in key markets?
The Most Favored Nation (MFN) duty rates for HS 2917.19 vary significantly by importing country. For example, the United States (HTSUS) generally applies an MFN duty rate of 6.5% ad valorem. The European Union (TARIC) typically applies a 6.5% ad valorem duty rate. The United Kingdom Global Tariff (UKGT) also lists a 6.5% ad valorem rate. It is crucial for importers to consult the specific tariff schedule of the destination country, such as the USITC HTSUS, EU TARIC, or UK Trade Tariff, for the most current and accurate MFN rates, as these can be subject to change.
Are there any preferential duty rates available for HS 2917.19 under common trade agreements, and how can importers claim them?
Yes, preferential duty rates, including 'Free' (0.00% ad valorem), are often available for products classified under HS 2917.19 when originating from countries with which the importing nation has a Free Trade Agreement (FTA) or other preferential trade arrangements. For instance, in the U.S., goods originating from countries like 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 duty-free entry under their respective FTAs. To claim preferential rates, importers must ensure the goods meet the rules of origin criteria of the specific agreement and provide valid proof of origin, such as a certificate of origin or an origin declaration, to the customs authorities at the time of import. Failure to provide proper documentation will result in the application of the MFN rate.
What are the key classification criteria for determining if a product falls under HS 2917.19 versus other subheadings within Chapter 29?
HS 2917.19 is the 'Other' subheading for acyclic polycarboxylic acids, their anhydrides, halides, peroxides, peroxyacids, and their derivatives. The primary classification criteria involve verifying that the chemical compound is an 'acyclic polycarboxylic acid' or a specified derivative thereof, and that it is not more specifically provided for in subheadings 2917.11 (Oxalic acid, its salts and esters) or 2917.12 (Adipic acid, its salts and esters). Importers and customs brokers must refer to the Harmonized System Explanatory Notes (HSEN) for Chapter 29, specifically for heading 29.17, to understand the precise chemical structure and functional group requirements. A detailed chemical analysis or specification sheet for the product is often necessary to confirm its exact chemical identity and ensure correct classification.
Are there any specific documentation requirements, beyond standard customs entry paperwork, for importing chemicals under HS 2917.19?
Beyond standard commercial invoices, packing lists, and bills of lading/air waybills, importers of chemicals under HS 2917.19 should be prepared to provide additional documentation. This may include a Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) to comply with chemical safety regulations, a Certificate of Analysis (CoA) detailing the chemical composition and purity, and potentially a Certificate of Origin if preferential duty rates are being claimed. Depending on the specific chemical and the importing country's regulations, permits or licenses from environmental agencies (e.g., EPA in the U.S.) or chemical control authorities may also be required, especially if the substance is subject to specific chemical inventories or restrictions (e.g., TSCA in the U.S., REACH in the EU). It is advisable to verify all specific requirements with the relevant regulatory bodies prior to importation.
