HS 290382 Aldrin (ISO), chlordane (ISO) and heptachlor (ISO)
Quick Answer: HS code 2903.82 specifically covers three persistent organic pollutants (POPs): Aldrin, Chlordane, and Heptachlor. These are chlorinated cyclodiene insecticides, now largely restricted or banned globally due to their environmental persistence and toxicity. Importers and exporters dealing with these chemicals, even for research or permitted uses, must be aware of stringent international conventions like the Stockholm Convention on POPs. Current Most Favored Nation (MFN) duty rates vary: the UK applies a 4.00% ad valorem rate, the EU's TARIC system shows 5.50%, and the US MFN rate is 5.5% ad valorem. The US also offers preferential duty treatment (Free) under various trade agreements (e.g., A, AU, BH, CL, KR) and a column 2 rate of 15.4¢/kg + 64.5%. Due to their hazardous nature, strict import/export licensing and permitting are typically required across all jurisdictions.

How to Classify This HS Code?
What products does HS 290382 cover?
This subheading covers three specific chlorinated hydrocarbon insecticides: Aldrin (ISO), Chlordane (ISO), and Heptachlor (ISO). These are distinct chemical compounds, defined by their International Organization for Standardization (ISO) common names, ensuring precise identification within the Harmonized System. As per the World Customs Organization (WCO) Harmonized System Nomenclature and reflected in national tariffs like the USITC Harmonized Tariff Schedule (HTSUS) and the EU TARIC, this classification is reserved exclusively for these three chemically pure or technically pure substances, provided they meet the purity requirements for organic chemicals of Chapter 29. Their primary use as pesticides is a key characteristic, but classification is based on their chemical identity.
What falls outside HS 290382?
The following products are excluded from HS 290382: mixtures containing Aldrin, Chlordane, or Heptachlor combined with other substances, such as solvents, diluents, or other active ingredients, which are generally classified under Heading 3808 as insecticides. For instance, a formulated pesticide product containing Chlordane as an active ingredient, but also including inert carriers, would fall under 3808. Other chlorinated derivatives of hydrocarbons not specifically named, even if they possess insecticidal properties, are also excluded and would be classified elsewhere in Heading 2903 or other relevant headings based on their chemical structure. For example, DDT (dichlorodiphenyltrichloroethane) is classified under HS 2903.89.00.
What are common classification mistakes for HS 290382?
A common error is attempting to classify formulated pesticide products containing Aldrin, Chlordane, or Heptachlor under HS 290382. According to General Interpretative Rule (GRI) 3(a), when goods are prima facie classifiable under two or more headings, the heading which provides the most specific description shall be preferred. In this context, Heading 3808 specifically covers "Insecticides, rodenticides, fungicides, herbicides, anti-sprouting products and plant-growth regulators, disinfectants and similar products, put up in forms or packings for retail sale or as preparations or articles." Therefore, a mixture or preparation, even if predominantly composed of one of these chemicals, is more specifically described by Heading 3808. Another mistake is misidentifying the specific isomer or derivative, leading to incorrect classification within Heading 2903.
How should importers classify products under HS 290382?
The correct procedure for classifying products under HS 290382 involves a rigorous chemical identification process. Importers and customs brokers must first confirm through laboratory analysis or supplier documentation that the product is chemically pure Aldrin (ISO), Chlordane (ISO), or Heptachlor (ISO). This requires verifying the Chemical Abstracts Service (CAS) registry number and chemical structure against official references. If the product is a mixture or preparation, even if it contains one of these chemicals, it should be classified under Heading 3808 as an insecticide preparation, not under 290382. Always consult the WCO Explanatory Notes for Chapter 29 and Heading 3808, and refer to national tariff schedules such as the USITC HTSUS or EU TARIC for specific duty rates and any applicable import restrictions or prohibitions, as these substances are often subject to strict environmental regulations.

FAQ
What are the standard Most Favored Nation (MFN) import duty rates for products classified under HS 2903.82 (Aldrin, Chlordane, and Heptachlor)?
The standard MFN (Most Favored Nation) import duty rates for products under HS 2903.82 can vary significantly by importing country. For example, the United States Harmonized Tariff Schedule (HTSUS) may list a rate of 4.0% ad valorem, while other jurisdictions, such as the EU TARIC, might apply a rate of 5.5% ad valorem. 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 precise and current MFN duty rate applicable at the time of importation.
Are there any preferential duty rates or free trade agreements that apply to HS 2903.82 for imports into the United States?
Yes, preferential duty rates, including 'Free' status, are available for HS 2903.82 under various U.S. free trade agreements and preference programs. For imports into the United States, products originating from countries such as 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. Importers must ensure they meet the rules of origin requirements of the respective trade agreement and provide proper documentation, such as a certificate of origin, to claim these preferential rates.
What are the key classification criteria for distinguishing Aldrin, Chlordane, and Heptachlor under HS 2903.82, and what common errors should be avoided?
HS 2903.82 specifically covers Aldrin (ISO), Chlordane (ISO), and Heptachlor (ISO), which are cyclodiene organochlorine insecticides. The primary classification criterion is the chemical identity of the substance. Importers and customs brokers must ensure that the chemical name and CAS (Chemical Abstracts Service) number on product specifications, safety data sheets (SDS), and commercial invoices precisely match one of these three compounds. Common classification errors include misidentifying isomers or related but distinct organochlorine compounds, or failing to provide sufficient chemical documentation to substantiate the exact identity of the substance. Referencing the WCO Explanatory Notes for Chapter 29 can provide further clarity on the scope of this heading.
What specific documentation is required for the importation of Aldrin, Chlordane, and Heptachlor (HS 2903.82), especially considering their environmental regulations?
Beyond standard customs documentation (commercial invoice, packing list, bill of lading/air waybill), the importation of substances like Aldrin, Chlordane, and Heptachlor under HS 2903.82 often requires additional permits and certifications due to their classification as Persistent Organic Pollutants (POPs) under international agreements like the Stockholm Convention. Importers typically need to provide: 1) A Safety Data Sheet (SDS) detailing chemical composition and hazards, 2) A Certificate of Analysis (CoA) confirming purity and identity, and 3) Any required import permits or licenses from environmental protection agencies (e.g., EPA in the U.S.) or equivalent regulatory bodies in the importing country. These substances are often subject to strict controls, and their import may be restricted or prohibited in many jurisdictions.
Are there any unusually high or complex duty rates that might apply to HS 2903.82, such as anti-dumping or countervailing duties?
While the standard MFN rates for HS 2903.82 are typically ad valorem (e.g., 4.0% or 5.5%), it is possible for specific products within this classification, originating from certain countries, to be subject to additional duties such as anti-dumping duties (ADD) or countervailing duties (CVD). Although not universally applied to Aldrin, Chlordane, or Heptachlor at present, such duties can be substantial, sometimes expressed as a combination of a specific duty and an ad valorem rate (e.g., '15.4¢/kg + 64.5% ad valorem'). Importers must regularly check the trade remedies databases of the importing country (e.g., U.S. Department of Commerce, EU Commission) to ascertain if any ADD or CVD orders are in effect for the specific product and country of origin at the time of importation, as these can significantly impact the total landed cost.
