HS 291615 Oleic, linoleic or linolenic acids, their salts and esters

Quick Answer: HS code 291615 covers unsaturated acyclic monocarboxylic acids, specifically oleic, linoleic, and linolenic acids, along with their respective salts and esters. These compounds are widely used in various industries, including cosmetics, pharmaceuticals, and as chemical intermediates. Importers and customs brokers should note the varying duty rates across major jurisdictions. In the UK, the standard Most Favoured Nation (MFN) duty rate is 6.00% ad valorem. The EU applies an MFN rate of 6.50% ad valorem. For the US, the MFN duty rate is 6.5% ad valorem, though many products under this code may qualify for duty-free entry under various Free Trade Agreements (e.g., A+, AU, BH, CL, CO, D, E, IL, JO, KR, MA, OM, P, PA, PE, S, SG). Conversely, certain products may face a higher Column 2 duty rate of 35.2%. Careful classification and origin verification are crucial to leverage preferential trade agreements and avoid unexpected costs.

How to Classify This HS Code?

What products does HS 291615 cover?

This subheading covers oleic acid, linoleic acid, and linolenic acid, along with their respective salts and esters. These are unsaturated acyclic monocarboxylic acids, which are key components in various industrial applications, including the production of soaps, detergents, lubricants, and cosmetics. The WCO Harmonized System Nomenclature for Chapter 29 specifically identifies these distinct chemical compounds, and this classification is consistently applied across national tariffs such as the USITC Harmonized Tariff Schedule (HTSUS) and the EU TARIC system, ensuring global uniformity for these specific fatty acids and their derivatives.

What falls outside HS 291615?

The following products are excluded from HS 291615: saturated acyclic monocarboxylic acids, such as palmitic acid or stearic acid, which are classified under other subheadings within Heading 2915. Additionally, mixtures of fatty acids that do not predominantly consist of oleic, linoleic, or linolenic acids, or their salts and esters, would typically be classified elsewhere, often under Chapter 38 if they are prepared mixtures not specifically provided for in Chapter 29. For instance, crude tall oil fatty acids, which are complex mixtures, are generally classified under HS 3823. Also, chemically modified derivatives beyond simple salts and esters, such as epoxidized oils, would fall outside this specific subheading.

What are common classification mistakes for HS 291615?

A common error is misclassifying mixtures containing these acids but not predominantly consisting of them, or confusing them with their saturated counterparts. Importers sometimes incorrectly classify complex fatty acid mixtures under 291615, even when other fatty acids are present in significant quantities, rather than considering Chapter 38 for prepared mixtures or other specific headings for individual saturated acids. 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. Furthermore, failing to distinguish between the free acids and their salts or esters, or misidentifying the specific acid present, can lead to incorrect classification.

How should importers classify products under HS 291615?

The correct procedure for classifying products under HS 291615 involves first confirming the precise chemical identity of the product. Importers and customs brokers should obtain a detailed Certificate of Analysis (CoA) or Safety Data Sheet (SDS) from the manufacturer, clearly stating the chemical name (oleic acid, linoleic acid, linolenic acid) and whether it is the free acid, a salt, or an ester. Verification that the product is an unsaturated acyclic monocarboxylic acid, and specifically one of the three named, is paramount. If the product is a mixture, its predominant component must be one of these specific acids or their derivatives. Consulting the WCO Explanatory Notes for Chapter 29 provides further guidance on the scope of these chemical classifications.

FAQ

What are the standard Most Favored Nation (MFN) import duty rates for products classified under HS 2916.15 (Oleic, linoleic or linolenic acids, their salts and esters) in major markets?

The MFN (Most Favored Nation) duty rates for HS 2916.15 vary by importing country. For example, the general MFN duty rate in the United States is 6.5% ad valorem, as per the Harmonized Tariff Schedule of the United States (HTSUS). In the European Union, the MFN duty rate is typically 6.5% ad valorem, as published in the EU TARIC. Importers should always consult the specific tariff schedule of the importing country for the most current and accurate MFN duty rates.

Are there any preferential duty rates available for HS 2916.15 under common trade agreements, and how can an importer claim them?

Yes, preferential duty rates, including duty-free treatment, are available for HS 2916.15 under various Free Trade Agreements (FTAs) and special programs. For instance, imports into the U.S. from countries like Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Korea (KR), Panama (PA), Peru (PE), and Singapore (SG) may qualify for duty-free entry under their respective FTAs. To claim preferential duty rates, importers must ensure the goods meet the specific Rules of Origin criteria outlined in the applicable trade agreement and provide valid documentation, such as a certificate of origin or a declaration of origin, to the customs authorities at the time of import. It is crucial to verify the specific origin requirements for each agreement.

What are the key classification criteria for products under HS 2916.15, and what distinguishes it from other related HS codes?

HS 2916.15 specifically covers 'Oleic, linoleic or linolenic acids, their salts and esters.' The primary classification criteria revolve around the chemical identity of the substance. Importers must confirm that the product is one of these specific fatty acids (oleic, linoleic, or linolenic acid) or a derivative in the form of a salt or ester. This sub-heading is distinct from other fatty acids or their derivatives classified elsewhere in Chapter 29 (e.g., saturated acyclic monocarboxylic acids in 2915) or mixtures of fatty acids (which might fall under Chapter 38 if not chemically defined single compounds). Accurate chemical analysis and product specifications are essential for correct classification, aligning with the Explanatory Notes to the Harmonized System.

What documentation is typically required by customs authorities for the importation of goods classified under HS 2916.15?

Standard import documentation for HS 2916.15 typically includes a commercial invoice, packing list, bill of lading or air waybill, and a customs declaration form. For chemical products, additional documentation is often required to ensure compliance with regulatory standards. This may include a Certificate of Analysis (CoA) detailing the chemical composition and purity, a Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) for hazardous material assessment, and potentially a manufacturer's declaration confirming the product's identity. If claiming preferential duty rates, a valid certificate or declaration of origin is also mandatory. Importers should consult the specific import requirements of the destination country's customs authority.

Are there any specific anti-dumping or countervailing duties (AD/CVD) that might apply to products under HS 2916.15?

While HS 2916.15 generally covers a broad range of chemical compounds, specific anti-dumping or countervailing duties (AD/CVD) can be imposed on certain products within this classification, often targeting specific countries of origin. For example, the U.S. has historically applied AD/CVD to various chemical imports. Importers must regularly check the official trade remedy websites of the importing country (e.g., U.S. Department of Commerce, EU Commission Trade Defence) to determine if any active AD/CVD orders apply to their specific product, country of origin, and manufacturer. Failure to account for these duties can result in significant penalties and retroactive duty assessments, with some rates potentially being as high as 35.2% or more, as indicated in past cases.
