HS 291536 Dinoseb (ISO) acetate
Quick Answer: HS code 291536 specifically covers Dinoseb (ISO) acetate, a chemical compound primarily used as a herbicide and acaricide. This organic chemical falls under Chapter 29, which encompasses organic chemicals, and more specifically within subheading 2915.36, indicating its classification as an acetic acid ester. Importers and exporters should note the varying duty rates: the UK applies a 4.00% ad valorem duty, while the EU imposes 5.50% ad valorem. In the US, the Most Favored Nation (MFN) rate is 5.5% ad valorem, with additional specific duties of 15.4¢/kg + 57% for certain non-MFN countries. However, many US Free Trade Agreement partners (e.g., Australia, Chile, Korea, Mexico, Singapore) benefit from a "Free" duty rate. Due to its nature as a pesticide, regulatory compliance beyond customs duties, such as environmental and health agency approvals, is crucial for trade in Dinoseb acetate.

How to Classify This HS Code?
What products does HS 291536 cover?
This subheading covers Dinoseb (ISO) acetate, which is chemically known as 2-(1-methylpropyl)-4,6-dinitrophenyl acetate. It is an ester of acetic acid and dinoseb, falling under Heading 2915 for saturated acyclic monocarboxylic acids and their anhydrides, halides, peroxides, peroxyacids, and their halogenated, sulphonated, nitrated or nitrosated derivatives. The World Customs Organization (WCO) Harmonized System Explanatory Notes for Chapter 29 confirm that specific chemical compounds, identified by their International Organization for Standardization (ISO) common names, are classified in their respective subheadings when provided. Both the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC system explicitly list "Dinoseb (ISO) acetate" under this specific six-digit code, ensuring consistent global classification for this particular chemical compound.
What falls outside HS 291536?
The following products are excluded from HS 291536: Dinoseb (ISO) itself, which is 2-(1-methylpropyl)-4,6-dinitrophenol, and would be classified under a different subheading, likely within Chapter 29, potentially 2908. Similarly, other esters of dinoseb, such as dinoseb methyl ester or dinoseb propargyl, would not be classified here as they are distinct chemical compounds, even if structurally related. Mixtures containing dinoseb acetate, where the dinoseb acetate is not the predominant component or where the mixture is prepared for a specific use (e.g., as a pesticide formulation), might be classified elsewhere in Chapter 38, depending on their composition and intended application, as per Chapter 38 legal notes.
What are common classification mistakes for HS 291536?
A common error is misclassifying Dinoseb (ISO) acetate as Dinoseb (ISO) itself, or as another ester of Dinoseb. This mistake often arises from insufficient attention to the precise chemical name and structure, particularly the "acetate" suffix. Another frequent error is classifying mixtures containing Dinoseb (ISO) acetate directly under 291536 when the mixture's characteristics dictate classification elsewhere, such as in Chapter 38 for pesticide preparations. General Interpretative Rule (GRI) 1 emphasizes that classification is determined according to the terms of the headings and any relative section or chapter notes, while GRI 6 dictates that classification at the subheading level is determined according to the terms of those subheadings and any related subheading notes, mutatis mutandis, applying GRIs 1 to 5.
How should importers classify products under HS 291536?
The correct procedure for classifying products under HS 291536 requires meticulous attention to the chemical identity. Importers and customs brokers must first verify that the product is indeed Dinoseb (ISO) acetate, ensuring the chemical name and CAS number (e.g., 2813-95-8) precisely match the description. This often necessitates obtaining a Certificate of Analysis (CoA) or Safety Data Sheet (SDS) from the manufacturer, which clearly states the chemical name, purity, and structure. If the product is a mixture, the importer must determine if Dinoseb (ISO) acetate is the sole or principal active ingredient, or if the mixture is a prepared formulation for a specific use, which might lead to classification in Chapter 38. Consulting the WCO Explanatory Notes for Chapter 29 and relevant national tariff interpretations (e.g., USITC HTS General Notes, EU TARIC guidance) is crucial to ensure accurate and compliant classification.

FAQ
What are the standard Most Favored Nation (MFN) import duty rates for HS code 2915.36 (Dinoseb (ISO) acetate) in major trading blocs?
The MFN import duty rates for HS 2915.36 (Dinoseb (ISO) acetate) vary by customs territory. For example, the United States applies a general MFN duty rate of 4.0% ad valorem. The European Union's TARIC database indicates a standard MFN duty rate of 5.5% ad valorem. The UK Global Tariff also lists a 5.5% ad valorem MFN duty rate. It is crucial for importers to verify the specific duty rate applicable to their destination country using the official tariff schedules (e.g., USITC Harmonized Tariff Schedule, EU TARIC, UK Trade Tariff).
Are there any preferential duty programs or free trade agreements that offer reduced or zero duties for Dinoseb (ISO) acetate (HS 2915.36)?
Yes, many preferential duty programs and Free Trade Agreements (FTAs) offer reduced or zero duties for products classified under HS 2915.36. For instance, in the United States, Dinoseb (ISO) acetate may be eligible for duty-free treatment under various programs and agreements, often denoted by special program indicators (SPIs) like A+, AU, BH, CL, CO, D, E, IL, JO, K, KR, MA, OM, P, PA, PE, S, SG. These include agreements with Australia, Bahrain, Chile, Colombia, Israel, Jordan, Korea, Morocco, Oman, Panama, Peru, Singapore, and others. Importers must ensure they meet the rules of origin requirements and provide proper documentation (e.g., certificate of origin) to claim preferential tariff treatment. Always consult the specific FTA text and the importing country's tariff schedule for precise eligibility criteria.
What are the key classification criteria for Dinoseb (ISO) acetate under HS 2915.36, and what distinguishes it from similar chemicals?
HS code 2915.36 specifically covers 'Dinoseb (ISO) acetate'. The primary classification criterion is the chemical identity of the substance. Dinoseb (ISO) acetate is an ester of acetic acid and Dinoseb, which is a dinitrophenol derivative. It falls under Chapter 29 of the Harmonized System, which covers organic chemicals, and more specifically under subheading 2915 for saturated acyclic monocarboxylic acids and their anhydrides, halides, peroxides, peroxyacids and their halogenated, sulphonated, nitrated or nitrosated derivatives, and their esters. The '36' further specifies the particular ester, Dinoseb (ISO) acetate. Distinguishing it from similar chemicals requires precise chemical identification, often through analytical testing, to confirm the presence of the Dinoseb moiety esterified with acetic acid, ensuring it is not a different ester or an unesterified Dinoseb.
What specific documentation is typically required by customs authorities for the import of Dinoseb (ISO) acetate (HS 2915.36)?
For the import of Dinoseb (ISO) acetate (HS 2915.36), standard customs documentation includes a commercial invoice, packing list, bill of lading or air waybill, and a certificate of origin. Additionally, as Dinoseb is a pesticide, it is subject to strict regulatory controls in many countries. Importers may need to provide specific permits or licenses from environmental protection agencies or agricultural departments (e.g., EPA in the US, ECHA in the EU). A Safety Data Sheet (SDS) is almost always required for chemical imports to provide information on hazards and safe handling. If claiming preferential duty rates, a valid certificate of origin or declaration of origin is mandatory. Compliance with chemical registration schemes (e.g., REACH in the EU) may also be necessary.
