HS 291040 Dieldrin (ISO, INN)

Quick Answer: HS code 291040 specifically covers Dieldrin, an organochlorine insecticide. While historically used in agriculture and for vector control, Dieldrin is now largely restricted or banned globally due to its persistence in the environment and toxicity. For importers and exporters, understanding these restrictions is paramount. Across major jurisdictions, the duty rates for Dieldrin vary. The UK and EU apply a 0.00% ad valorem duty rate. In the United States, the Most Favored Nation (MFN) duty rate is 4.8% ad valorem, though many countries benefit from duty-free treatment under various Free Trade Agreements (e.g., A, AU, CL). A higher Column 2 rate of 31% applies to non-MFN countries. Importers must verify the legality of Dieldrin shipments in both origin and destination countries, often requiring specific permits or certifications due to its hazardous nature and international conventions like the Stockholm Convention on Persistent Organic Pollutants.

How to Classify This HS Code?

What products does HS 291040 cover?

This subheading covers Dieldrin (ISO, INN), which is an organochlorine insecticide. Specifically, it refers to the chemical compound 1,2,3,4,10,10-hexachloro-6,7-epoxy-1,4,4a,5,6,7,8,8a-octahydro-endo-1,4-exo-5,8-dimethanonaphthalene. As per the Harmonized System Nomenclature, Heading 2910 encompasses epoxides, epoxyalcohols, epoxyphenols and epoxyethers, with a three-membered ring, and their halogenated, sulphonated, nitrated or nitrosated derivatives. Dieldrin, being an epoxide with a three-membered ring and halogenated, perfectly aligns with this description and the specific product definition provided by the USITC Harmonized Tariff Schedule and the EU TARIC system for this particular eight-digit subheading.

What falls outside HS 291040?

The following products are excluded from HS 291040: other epoxides not specifically named as Dieldrin, even if they share similar chemical structures or insecticidal properties. For instance, Aldrin (ISO, INN), which is structurally related but lacks the epoxy group, is classified under HS 2903. Similarly, Endrin (ISO, INN), an isomer of Dieldrin, is classified under HS 291090. Preparations containing Dieldrin, such as formulated insecticides ready for retail sale, are generally excluded from Chapter 29 and would typically fall under Chapter 38, specifically heading 3808, which 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.

What are common classification mistakes for HS 291040?

A common error is misclassifying Dieldrin when it is part of a mixture or preparation, rather than in its pure chemical form. Importers sometimes incorrectly apply HS 291040 to formulated insecticide products containing Dieldrin, failing to recognize that Chapter 29 is reserved for separate chemically defined organic compounds. According to General Interpretative Rule (GRI) 1, classification is determined according to the terms of the headings and any relative section or chapter notes. GRI 3(b) would apply if Dieldrin were merely one component of a mixture, directing classification to the component that gives the mixture its essential character, which for an insecticide preparation would typically be heading 3808. Another mistake is confusing Dieldrin with its isomers or other related organochlorine compounds, leading to incorrect classification within Heading 2910 or even entirely different headings.

How should importers classify products under HS 291040?

The correct procedure for classifying Dieldrin (ISO, INN) under HS 291040 involves verifying that the product is indeed the pure, separate chemically defined compound Dieldrin, and not a mixture or preparation. Importers and customs brokers should obtain a Certificate of Analysis (CoA) or Safety Data Sheet (SDS) from the manufacturer to confirm the chemical identity, purity, and CAS number (60-57-1 for Dieldrin). This documentation is crucial for demonstrating that the product meets the specific chemical definition of Dieldrin as an epoxide with a three-membered ring, falling squarely within Heading 2910. If the product is a formulated insecticide, it must be classified under Chapter 38, typically heading 3808, even if Dieldrin is the active ingredient. Always consult the most current version of the USITC Harmonized Tariff Schedule or EU TARIC for specific national duty rates and import requirements.

FAQ

What is the Most Favored Nation (MFN) duty rate for Dieldrin (HS 2910.40) in key markets, and are there any significant variations?

The MFN duty rate for Dieldrin (HS 2910.40) can vary significantly by importing country. For example, the United States generally applies a 'Free' (0.00%) MFN duty rate according to the Harmonized Tariff Schedule of the United States (HTSUS). Similarly, the EU TARIC database often shows a 0.00% MFN duty rate for this heading. However, other countries may apply higher rates, such as 4.8% or even 31% in certain jurisdictions. Importers must consult the specific national tariff schedule of the country of importation to determine the exact MFN duty rate applicable at the time of entry. These rates are subject to change based on national trade policy and WCO recommendations.

Are there any preferential duty rates available for Dieldrin (HS 2910.40) under common trade agreements?

Yes, preferential duty rates are frequently available for Dieldrin (HS 2910.40) when imported from countries that have Free Trade Agreements (FTAs) or other preferential trade programs with the importing nation. Based on the provided sample, a 'Free' (0.00%) preferential rate is common under agreements with 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), Singapore (SG), and others (indicated by A, D, E, K, P, S). To claim preferential duty rates, importers must ensure the goods meet the Rules of Origin criteria specified in the relevant trade agreement and possess the required Certificates of Origin or other documentation (e.g., declarations) at the time of import.

What are the key classification criteria for Dieldrin under HS 2910.40, and what should importers be aware of to ensure correct classification?

HS 2910.40 specifically covers 'Dieldrin (ISO, INN)'. The classification hinges on the chemical identity of the substance. Dieldrin is an organochlorine insecticide that falls under Chapter 29 of the Harmonized System, which covers 'Organic chemicals'. Specifically, it is an epoxide, which places it within heading 2910 ('Epoxides, epoxyalcohols, epoxyphenols and epoxyethers, with a three-membered ring, and their halogenated, sulphonated, nitrated or nitrosated derivatives'). Importers must ensure that the product being declared is indeed chemically Dieldrin, conforming to its International Organization for Standardization (ISO) or International Nonproprietary Name (INN) specifications. Misclassification could occur if the product is a mixture containing Dieldrin but not primarily Dieldrin, or if it's a different but related chemical. Chemical analysis reports or Safety Data Sheets (SDS) are crucial for verifying the exact chemical composition and ensuring accurate classification.

What documentation is typically required for importing Dieldrin (HS 2910.40), especially considering its nature as a chemical substance?

Beyond standard customs documentation such as the commercial invoice, packing list, and bill of lading/air waybill, importing Dieldrin (HS 2910.40) often requires specific regulatory documentation due to its chemical nature and potential environmental or health impacts. Key documents may include:

  1. Safety Data Sheet (SDS): Essential for identifying chemical properties, hazards, and safe handling.
  2. Certificate of Analysis (CoA): Verifies the chemical composition and purity.
  3. Certificate of Origin: Required to claim preferential duty rates under trade agreements.
  4. Import Licenses/Permits: Dieldrin is a persistent organic pollutant (POP) and its production, use, and trade are severely restricted or banned under international conventions like the Stockholm Convention. Many countries require specific import permits from environmental or chemical control agencies.
  5. Customs Declaration: Must accurately reflect the HS code, value, origin, and quantity. Importers should consult the specific import regulations of the destination country, as requirements for restricted chemicals can be stringent and vary significantly.
