HS 293392 Azinphos-methyl (ISO)
Quick Answer: HS code 293392 specifically covers Azinphos-methyl (ISO), an organophosphate insecticide. This chemical compound is primarily used in agriculture for pest control on various crops, though its use is restricted or banned in many countries due to environmental and health concerns. For importers and exporters, understanding these restrictions is crucial. Duty rates vary significantly: the UK applies a 6.00% ad valorem duty, while the EU TARIC system shows a 6.50% ad valorem rate. In the United States, the Harmonized Tariff Schedule (HTS) indicates a complex duty structure of Free, 15.4¢/kg + 64.5% ad valorem, depending on the specific tariff line and applicable trade programs. Importers must verify the exact duty rate and any import permit requirements with the relevant customs authorities prior to shipment.

How to Classify This HS Code?
What products does HS 293392 cover?
This subheading covers Azinphos-methyl (ISO), a specific heterocyclic compound with a nitrogen hetero-atom(s) only, falling under Heading 2933 of the Harmonized System. Azinphos-methyl is chemically defined as O,O-dimethyl S-[(4-oxo-1,2,3-benzotriazin-3(4H)-yl)methyl] phosphorodithioate. As per the World Customs Organization (WCO) Harmonized System Nomenclature and confirmed by official sources like the USITC Harmonized Tariff Schedule and the EU TARIC, this classification is precise for the pure chemical compound, used primarily as an insecticide and acaricide in agricultural applications. Its chemical structure, featuring a triazine ring, is the definitive characteristic for its inclusion here.
What falls outside HS 293392?
The following products are excluded from HS 293392: mixtures containing Azinphos-methyl but formulated for specific uses, which would typically be classified in Chapter 38, specifically under Heading 3808 as 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. For instance, an insecticide spray containing Azinphos-methyl as an active ingredient, ready for consumer use, would not be classified here. Similarly, other heterocyclic compounds, even those with similar applications but different chemical structures, would fall under other subheadings within Heading 2933 or other chapters entirely, depending on their specific chemical identity.
What are common classification mistakes for HS 293392?
A common error is misclassifying formulated products containing Azinphos-methyl as the pure chemical compound under HS 293392. Importers often overlook General Interpretative Rule (GRI) 3(b), which dictates that mixtures and composite goods are classified according to the material or component which gives them their essential character. Therefore, an insecticide preparation where Azinphos-methyl is the active ingredient, but combined with other substances and put up for retail sale, should be classified under Heading 3808, not as the pure chemical. Another mistake is confusing Azinphos-methyl with other similar but distinct heterocyclic compounds, leading to incorrect classification within Heading 2933 or even outside it, if the chemical structure does not precisely match the definition.
How should importers classify products under HS 293392?
The correct procedure for classifying products under HS 293392 involves first verifying the precise chemical identity of the substance. Importers and customs brokers must ensure that the product is indeed pure Azinphos-methyl (ISO) and not a mixture or formulation. This requires obtaining a Certificate of Analysis (CoA) or Safety Data Sheet (SDS) from the manufacturer, which clearly states the chemical name, CAS number (86-50-0), and purity. If the product is a preparation or mixture, even if Azinphos-methyl is the primary active ingredient, it should be classified under Chapter 38, specifically Heading 3808, following GRI 3(b). Always consult the WCO Explanatory Notes for Heading 2933 and Chapter 38, alongside national tariff schedules like the USITC HTS or EU TARIC, for definitive guidance.

FAQ
What is Azinphos-methyl (ISO) and why is it classified under HS 2933.92?
Azinphos-methyl (ISO) is an organophosphate insecticide. It is classified under Harmonized System (HS) subheading 2933.92 because it is a heterocyclic compound with nitrogen hetero-atom(s) only, specifically a compound containing an unfused pyridine ring (whether or not hydrogenated) in the structure, not further specified in other subheadings of Chapter 29. The 'ISO' designation indicates it is the International Organization for Standardization common name for the chemical substance, ensuring consistent identification in international trade. This classification is in accordance with General Interpretative Rule 1 and 6 of the Harmonized System.
What are the typical Most Favored Nation (MFN) duty rates for HS 2933.92, and are there any significant variations?
Most Favored Nation (MFN) duty rates for HS 2933.92 (Azinphos-methyl (ISO)) can vary significantly by importing country. For instance, the United States generally applies a 'Free' rate under the Harmonized Tariff Schedule of the United States (HTSUS) for MFN (Normal Trade Relations) countries. In contrast, some countries may apply ad valorem rates such as 6.00% or 6.50%. There are also instances of complex duty structures, such as 15.4¢/kg + 64.5% in certain markets, which typically apply to specific product forms or under particular trade policy conditions. Importers should always verify the exact duty rate with the customs authority of the destination country, referencing the latest national tariff schedule (e.g., USITC HTSUS, EU TARIC, UK Trade Tariff).
Are there any preferential duty rates or free trade agreements that commonly impact imports of Azinphos-methyl (HS 2933.92)?
Yes, preferential duty rates may apply to imports of Azinphos-methyl (HS 2933.92) depending on the country of origin and the existence of free trade agreements (FTAs) or special preference programs. For example, imports into the United States from countries party to agreements like the USMCA (United States-Mexico-Canada Agreement), CAFTA-DR (Dominican Republic-Central America FTA), or Generalized System of Preferences (GSP) beneficiary countries might be eligible for duty-free treatment or reduced rates, provided all rules of origin are met. Similarly, the EU's TARIC database would show preferential rates for imports from FTA partners or GSP beneficiaries. Importers must ensure they have the correct certificates of origin (e.g., NAFTA Certificate of Origin, EUR.1 movement certificate) to claim these preferential rates.
What specific documentation is required for importing Azinphos-methyl (HS 2933.92), given its nature as a chemical substance?
Beyond standard customs documentation such as a commercial invoice, packing list, and bill of lading/air waybill, importing Azinphos-methyl (HS 2933.92) typically requires additional regulatory compliance documents due to its chemical nature and use as an insecticide. Key documents may include: a Safety Data Sheet (SDS) for hazard communication, a Certificate of Analysis (CoA) confirming purity and specifications, and potentially permits or licenses from environmental protection agencies (e.g., EPA in the US, ECHA in the EU) or agricultural authorities, especially if it's a restricted or controlled substance. Compliance with chemical import regulations (e.g., TSCA in the US, REACH in the EU) is crucial, and pre-notification or registration might be necessary before importation.
Could HS 2933.92 be subject to anti-dumping or countervailing duties in certain markets?
It is possible for HS 2933.92, like any imported product, to be subject to anti-dumping (AD) or countervailing duties (CVD) if a specific country's trade authorities determine that imports are being 'dumped' (sold below fair value) or unfairly subsidized, causing material injury to a domestic industry. While there are no universally active AD/CVD measures for Azinphos-methyl across all markets at any given time, importers must always check the relevant trade remedy databases of the importing country (e.g., USITC, EU Trade Defence website) for any ongoing investigations or existing orders against specific countries of origin for this HS code. Failure to account for AD/CVD can result in significant unforeseen costs and penalties.
