HS 292425 Alachlor (ISO)

Quick Answer: HS code 292425 specifically covers Alachlor (ISO), a widely used herbicide belonging to the acetanilide class of organic chemical compounds. Importers and exporters dealing with this agricultural chemical should note the varying duty rates across major jurisdictions. For instance, 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 Most Favored Nation (MFN) duty rate is a compound rate of 15.4¢/kg + 5.8%, or 6.5% ad valorem, with many preferential trade agreements offering duty-free entry (e.g., under A+, AU, BH, CL, KR, SG). Accurate classification is crucial to ensure compliance and optimize duty costs, particularly given the specific nature of this chemical.

How to Classify This HS Code?

What products does HS 292425 cover?

This subheading covers Alachlor (ISO), which is specifically N-(2,6-diethylphenyl)-N-(methoxymethyl)chloroacetamide. Alachlor is an acetanilide herbicide used to control annual grasses and broadleaf weeds in various crops. As per the Harmonized System Nomenclature, Chapter 29 covers organic chemicals, and Heading 2924 specifically includes carboxyamide-function compounds; amide-function compounds of carbonic acid. The ISO (International Organization for Standardization) designation confirms its identity as a recognized chemical substance. Both the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC system precisely define this subheading as exclusively covering the chemical compound Alachlor.

What falls outside HS 292425?

The following products are excluded from HS 292425: other herbicides, even if they are also acetanilide derivatives, unless they are specifically Alachlor. For instance, other chloroacetanilide herbicides like butachlor (N-(butoxymethyl)-2-chloro-N-(2,6-diethylphenyl)acetamide) or metolachlor (2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl)acetamide) would be classified under other subheadings within Heading 2924, such as 2924.29.90 for "Other" carboxyamide-function compounds. Preparations containing Alachlor, such as formulated pesticides ready for retail sale, are generally 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.

What are common classification mistakes for HS 292425?

A common error is misclassifying other chloroacetanilide herbicides as Alachlor due to their similar chemical structures and functions. Importers might incorrectly apply HS 292425 to compounds like butachlor or metolachlor, which, while also herbicides and within Heading 2924, have distinct chemical identities and are therefore classified under different subheadings, typically 2924.29.90. This mistake often arises from a lack of precise chemical identification or an overreliance on product function rather than specific chemical structure, violating 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.

How should importers classify products under HS 292425?

The correct procedure for classifying products under HS 292425 involves verifying the exact chemical identity of the substance. Importers and customs brokers must obtain a Certificate of Analysis (CoA) or a Safety Data Sheet (SDS) from the manufacturer, clearly stating the chemical name as "Alachlor" and its Chemical Abstracts Service (CAS) registry number (15972-60-8). This documentation provides irrefutable proof of the substance's identity, ensuring compliance with GRI 1. If the product is a formulated preparation containing Alachlor, it should be classified under Chapter 38, specifically Heading 3808, as a herbicide preparation, rather than under Chapter 29, which is reserved for pure, unmixed organic chemicals.

FAQ

What is 'Alachlor (ISO)' under HS code 2924.25 and what are its primary uses?

HS code 2924.25 specifically covers 'Alachlor (ISO)'. Alachlor, an International Organization for Standardization (ISO) common name, is a chloroacetanilide herbicide primarily used in agriculture to control annual grasses and certain broadleaf weeds in crops such as corn, soybeans, and peanuts. It functions as a selective pre-emergent herbicide, inhibiting cell division and protein synthesis in germinating weeds. Importers should ensure that the product being classified precisely matches the chemical definition of Alachlor to avoid misclassification.

What are the Most Favored Nation (MFN) duty rates for HS 2924.25 'Alachlor (ISO)' and how can I determine if preferential rates apply?

The Most Favored Nation (MFN) duty rates for HS 2924.25 'Alachlor (ISO)' vary significantly by importing country. For example, the United States applies a general MFN duty rate of 6.5% ad valorem (USITC Harmonized Tariff Schedule, Chapter 29, Subheading 2924.25.00). The European Union's TARIC database indicates a general MFN duty rate of 6.5% ad valorem for this subheading. Other countries may have different MFN rates, such as 6.00% or even complex rates like '15.4¢/kg + 58%'.

To determine if preferential rates apply, importers must verify if the country of origin has a Free Trade Agreement (FTA) or other preferential trade program with the importing country. For instance, in the US, 'Alachlor (ISO)' may be eligible for 'Free' duty under various programs and FTAs with countries designated by symbols such as A+, AU, BH, CL, CO, D, E, IL, JO, K, KR, MA, OM, P, PA, PE, S, SG. Importers must ensure they meet the Rules of Origin requirements and possess valid Certificates of Origin or other required documentation to claim these preferential rates. Consult the specific country's customs tariff schedule (e.g., USITC HTS, EU TARIC, UK Trade Tariff) for the most accurate and up-to-date information.

What specific documentation is required for importing 'Alachlor (ISO)' under HS 2924.25, beyond standard customs paperwork?

Beyond standard customs documentation such as commercial invoices, packing lists, and bills of lading/air waybills, importing 'Alachlor (ISO)' (HS 2924.25) often requires additional regulatory compliance documentation due to its nature as an agricultural chemical. Importers may need to provide:

  1. Safety Data Sheet (SDS): Essential for hazard communication and regulatory compliance.
  2. Certificate of Analysis (CoA): Verifies the chemical composition, purity, and specifications of the Alachlor.
  3. Pesticide Registration Documentation: Depending on the importing country's regulations (e.g., EPA in the US, ECHA in the EU), the specific Alachlor product may need to be registered or approved for import and use. This could include import permits or notifications.
  4. Country of Origin Certificate: Crucial for claiming preferential duty rates under FTAs.
  5. Compliance with Chemical Control Regulations: Adherence to national chemical inventory lists and import restrictions (e.g., TSCA in the US, REACH in the EU).

Importers should consult the relevant environmental protection agencies and customs authorities in both the exporting and importing countries well in advance of shipment to ensure all specific requirements are met.

Are there any specific classification considerations or WCO Explanatory Notes relevant to HS 2924.25 'Alachlor (ISO)' that importers should be aware of?

For HS 2924.25, the primary classification consideration is the precise chemical identity of 'Alachlor (ISO)'. The World Customs Organization (WCO) Harmonized System Explanatory Notes for Chapter 29, specifically Section VI (Organic Chemicals), provide general guidance for classifying pure organic compounds. Alachlor is a specific amide (N-substituted amide) and is explicitly provided for at the 6-digit subheading level, meaning its chemical structure and common name are definitive for its classification here.

Importers must ensure that the product is indeed pure Alachlor or a mixture where Alachlor is the predominant active ingredient and the mixture's characteristics are defined by Alachlor. If the product is a formulated pesticide containing Alachlor mixed with other active ingredients or inert carriers, its classification might shift to Chapter 38, specifically subheading 3808.93 (Herbicides, anti-sprouting products and plant-growth regulators, not elsewhere specified or included, put up in forms or packings for retail sale or as preparations or articles). The distinction hinges on whether the imported product is the pure chemical compound (Chapter 29) or a prepared formulation (Chapter 38). Always refer to the General Rules for the Interpretation of the Harmonized System (GRIs), particularly GRI 1 and GRI 6, and the WCO Explanatory Notes for precise application.
