HS 291818 Chlorobenzilate (ISO)
Quick Answer: HS code 291818 specifically covers Chlorobenzilate (ISO), a chemical compound primarily used as an acaricide (miticide) to control mites on various crops and in other agricultural applications. Importers and customs brokers should note the varying duty rates across major jurisdictions. In the UK, the 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 rate is 6.5% ad valorem, but significant preferential duty programs offer duty-free entry for eligible goods from numerous countries (e.g., A+, AU, BH, CL, CO, etc.). Additionally, a higher Column 2 rate of 15.4¢/kg + 57% applies to goods from specific non-MFN countries. Accurate classification is crucial to ensure compliance and optimize duty costs.

How to Classify This HS Code?
What products does HS 291818 cover?
This subheading covers Chlorobenzilate (ISO), which is specifically identified by its International Organization for Standardization (ISO) common name. Chlorobenzilate is chemically known as ethyl 4,4'-dichlorobenzilate, a synthetic organic compound primarily used as an acaricide (miticide) in agriculture. Its classification here is dictated by its precise chemical structure and function as a carboxylic acid with additional oxygen function, falling under Heading 2918 for "Carboxylic acids with additional oxygen function and their anhydrides, halides, peroxides, peroxyacids and their halogenated, sulphonated, nitrated or nitrosated derivatives." The WCO Harmonized System Explanatory Notes for Chapter 29 and the USITC Harmonized Tariff Schedule (HTS) and EU TARIC system explicitly list "Chlorobenzilate (ISO)" under this specific eight-digit code, ensuring consistent global classification for this particular chemical.
What falls outside HS 291818?
The following products are excluded from HS 291818: any other acaricides or pesticides that are not Chlorobenzilate, even if they have similar chemical structures or uses. For instance, Dicofol, another chlorinated acaricide, would be classified under HS 2909.30 (Ethers, ether-alcohols, ether-phenols, ether-alcohol-phenols, peroxide-alcohols, peroxide-ethers, peroxide-ketones (chemically defined or not), and their halogenated, sulphonated, nitrated or nitrosated derivatives) or a more specific subheading if available, as it is an alcohol derivative, not a carboxylic acid with additional oxygen function. Similarly, other organic compounds used as pesticides but not matching the precise chemical definition of Chlorobenzilate, or those not having the ISO common name "Chlorobenzilate," would be classified elsewhere in Chapter 29 based on their specific functional groups and chemical structure, or in Chapter 38 if they are preparations.
What are common classification mistakes for HS 291818?
A common error is misclassifying other acaricides or pesticides with similar names or applications under HS 291818, failing to adhere to the strict chemical specificity of the Harmonized System. Importers might incorrectly classify a product based solely on its end-use as an acaricide rather than its precise chemical identity and functional groups. For example, confusing Chlorobenzilate with other chlorinated organic compounds that are not carboxylic acids with additional oxygen function, or not specifically named "Chlorobenzilate (ISO)," would lead to misclassification. This error often stems from neglecting General Interpretative Rule (GRI) 1, which states that classification is determined according to the terms of the headings and any relative section or chapter notes, and GRI 6, which extends this principle to subheadings, emphasizing the importance of the specific chemical name and structure.
How should importers classify products under HS 291818?
The correct procedure for classifying products under HS 291818 involves first verifying that the product is indeed Chlorobenzilate (ISO) by its precise chemical name, ethyl 4,4'-dichlorobenzilate, and its Chemical Abstracts Service (CAS) registry number (e.g., 510-15-6). Importers and customs brokers should obtain a Certificate of Analysis (CoA) or Safety Data Sheet (SDS) from the manufacturer, which clearly states the chemical name, purity, and CAS number. This documentation is crucial to confirm the product's identity against the specific description "Chlorobenzilate (ISO)" in the tariff schedule. Always cross-reference with the latest official tariff publications, such as the USITC HTS, EU TARIC, or UK Trade Tariff, to ensure the eight-digit code is current and applicable. If there is any doubt, seeking a binding ruling from the respective customs authority is the most prudent course of action to ensure compliance and avoid potential penalties.

FAQ
What is the Most Favored Nation (MFN) import duty rate for Chlorobenzilate (HS 2918.18) in key markets?
The MFN (Most Favored Nation) import duty rates for Chlorobenzilate (HS 2918.18) vary by importing country. For example, the United States applies a rate of 6.5% ad valorem. The European Union's TARIC database indicates a general MFN duty rate of 6.5% ad valorem. The UK Global Tariff also lists a 6.5% ad valorem rate. It is crucial for importers to verify the specific MFN rate applicable in their destination country through official customs tariff schedules like the USITC Harmonized Tariff Schedule, EU TARIC, or the UK Trade Tariff.
Are there any preferential duty programs or free trade agreements that offer reduced or zero duties for Chlorobenzilate (HS 2918.18)?
Yes, numerous preferential duty programs and Free Trade Agreements (FTAs) can offer reduced or zero duties for Chlorobenzilate (HS 2918.18) when originating from eligible countries. For instance, the United States grants duty-free treatment under various programs and agreements, including but not limited to, the Generalized System of Preferences (GSP) for eligible developing countries (symbol 'A'), agreements with 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). Importers should consult the specific FTA rules of origin and the importing country's tariff schedule to determine eligibility for these preferential rates, often indicated by specific preference program symbols.
What are the key classification criteria for Chlorobenzilate under HS 2918.18?
Chlorobenzilate (ISO) is classified under HS 2918.18 because it is an aromatic carboxylic acid with an additional oxygen function, specifically an ester of 4-chlorobenzoic acid. Heading 29.18 covers 'Carboxylic acids with additional oxygen function and their anhydrides, halides, peroxides, peroxyacids and their halogenated, sulphonated, nitrated or nitrosated derivatives.' Subheading 2918.18 specifically identifies 'Chlorobenzilate (ISO)'. The classification hinges on its precise chemical structure as defined by the International Organization for Standardization (ISO) and its functional groups, placing it within the category of carboxylic acids with additional oxygen functions.
What documentation is typically required for importing Chlorobenzilate (HS 2918.18)?
Importing Chlorobenzilate (HS 2918.18) typically requires standard customs documentation, including a commercial invoice, packing list, bill of lading or air waybill, and a certificate of origin (especially if claiming preferential duty rates). Given that Chlorobenzilate is an agricultural miticide and pesticide, additional regulatory documentation may be required by environmental protection agencies or agricultural departments in the importing country. For example, in the United States, importers may need to comply with regulations from the Environmental Protection Agency (EPA) under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), which could necessitate specific permits, registrations, or notifications. Importers should consult the relevant regulatory bodies in the destination country prior to shipment.
