HS 293141 Non-halogenated organo-phosphorous derivatives

Quick Answer: HS code 2931.41 covers non-halogenated organo-phosphorous derivatives, which are organic chemical compounds containing phosphorus, but without any halogen elements like chlorine or bromine. These chemicals are often used as intermediates in the production of pharmaceuticals, pesticides, flame retardants, and plasticizers. Importers and exporters should note the varying duty rates: the UK applies a 6.00% ad valorem duty, while the EU's TARIC system shows 6.50%. In the US, the Most Favored Nation (MFN) rate is 3.7% ad valorem, but numerous Free Trade Agreements (FTAs) offer duty-free entry (e.g., under General Notes 3(A), 3(AU), 3(BH), etc.). For goods not qualifying for FTA benefits, a 25% Column 2 rate applies. Accurate classification is crucial to leverage preferential duty rates.

How to Classify This HS Code?

What products does HS 293141 cover?

This subheading covers non-halogenated organo-phosphorous derivatives, specifically those containing a phosphorus atom directly bonded to at least one carbon atom, but excluding those where any halogen atoms are also directly bonded to the phosphorus or carbon atoms within the organic structure. As defined by the World Customs Organization (WCO) Harmonized System Nomenclature and reflected in the USITC Harmonized Tariff Schedule (HTSUS) and EU TARIC, this includes a wide array of organic compounds where phosphorus is an integral part of the molecular structure, such as phosphonates, phosphinates, and phosphine oxides, provided they are free from halogen substitution. Examples include certain flame retardants, plasticizers, and intermediates used in various chemical syntheses, all characterized by their organo-phosphorous nature without halogenation.

What falls outside HS 293141?

The following products are excluded from HS 293141: organo-phosphorous derivatives that contain any halogen atoms, which would typically fall under HS 2931.42 or other more specific subheadings if they are, for instance, halogenated phosphonates or phosphinates. Additionally, inorganic phosphorus compounds, such as phosphates or phosphites of metals, are excluded as they lack the direct carbon-phosphorus bond required for Heading 2931 and are generally classified in Chapter 28. Furthermore, organo-phosphorous compounds that are specifically provided for in other headings of Chapter 29, such as certain pesticides or pharmaceuticals, would be classified according to their specific function or chemical structure under those more specific headings, even if they meet the general chemical criteria for Heading 2931.

What are common classification mistakes for HS 293141?

A common error is misclassifying organo-phosphorous compounds that contain halogen atoms within their structure under HS 293141, when they should correctly be classified under HS 293142 ("Halogenated organo-phosphorous derivatives"). This mistake often arises from an incomplete analysis of the chemical structure, overlooking the presence of fluorine, chlorine, bromine, or iodine. Another frequent mistake involves classifying inorganic phosphorus compounds, such as tripotassium phosphate, under Heading 2931, despite their lack of a direct carbon-phosphorus bond, which is a fundamental requirement of the heading as per General Interpretative Rule (GRI) 1. Importers sometimes also fail to consider more specific headings in Chapter 29 that might take precedence for certain organo-phosphorous compounds with defined uses, such as certain insecticides or herbicides.

How should importers classify products under HS 293141?

The correct procedure for classifying products under HS 293141 involves a meticulous review of the chemical structure to confirm the presence of a direct carbon-phosphorus bond and, critically, the complete absence of any halogen atoms within the organic derivative. Importers and customs brokers should obtain the Chemical Abstracts Service (CAS) number and the full chemical name, along with the structural formula, from the manufacturer. This information should then be cross-referenced with the WCO Explanatory Notes for Heading 2931, the USITC HTSUS General Notes, and EU TARIC guidance to ensure compliance. If there is any ambiguity regarding the presence of halogens or if the compound has a specific function (e.g., a pesticide), further research into more specific Chapter 29 headings is warranted, potentially requiring a binding ruling from the relevant customs authority to ensure accuracy and mitigate compliance risks.

FAQ

What are the typical import duty rates for products classified under HS 2931.41 ('Non-halogenated organo-phosphorous derivatives') in major markets, and how can preferential rates be accessed?

The Most Favored Nation (MFN) import duty rates for HS 2931.41 can vary significantly by importing country. For instance, in the United States, the general MFN duty rate is 6.5% ad valorem, as per the Harmonized Tariff Schedule of the United States (HTSUS). In the European Union, the MFN duty rate under TARIC for this subheading is typically 6.00% ad valorem. The UK Global Tariff also lists a general duty rate of 6.00% ad valorem. However, many preferential trade agreements offer reduced or duty-free access. For example, imports into the U.S. from countries like Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Korea (KR), Panama (PA), Peru (PE), and Singapore (SG) may be eligible for duty-free treatment under various Free Trade Agreements (FTAs), provided the goods meet the respective Rules of Origin. Importers should consult the specific trade agreement's origin criteria and ensure proper documentation, such as a Certificate of Origin, is provided to claim preferential tariffs.

What are the key classification criteria for determining if a chemical product falls under HS 2931.41, specifically distinguishing 'non-halogenated' derivatives?

HS 2931.41 specifically covers 'Non-halogenated organo-phosphorous derivatives.' The primary classification criteria revolve around the chemical structure:

  1. Organo-phosphorous: The compound must contain at least one carbon-phosphorus bond. This distinguishes it from inorganic phosphorous compounds (e.g., phosphates, phosphites) which are classified elsewhere, typically in Chapter 28.
  2. Derivatives: It must be a derivative of an organo-phosphorous compound.
  3. Non-halogenated: This is a critical differentiator. The molecule must not contain any halogen atoms (Fluorine, Chlorine, Bromine, Iodine). If a halogen atom is present, even if it's an organo-phosphorous compound, it would typically be classified under HS 2931.42 ('Halogenated organo-phosphorous derivatives') or other more specific subheadings if applicable. Importers should review the chemical's structural formula and CAS (Chemical Abstracts Service) number, cross-referencing with the WCO Explanatory Notes for Chapter 29, to ensure accurate classification.
Are there specific documentation requirements or regulatory considerations for importing 'Non-halogenated organo-phosphorous derivatives' (HS 2931.41) beyond standard customs declarations?

Beyond standard commercial invoices, packing lists, and bills of lading, importers of HS 2931.41 may face additional documentation and regulatory requirements depending on the specific chemical and the importing country. While 'non-halogenated organo-phosphorous derivatives' are generally not subject to the same strict controls as certain halogenated compounds (e.g., under the Montreal Protocol or Stockholm Convention), some specific chemicals within this broad category might be regulated. For example, certain organo-phosphorous compounds can be precursors for chemical weapons or have dual-use applications, potentially requiring export/import licenses from authorities like the U.S. Bureau of Industry and Security (BIS) or similar agencies in other countries. Furthermore, compliance with chemical safety regulations (e.g., REACH in the EU, TSCA in the U.S.) often necessitates Safety Data Sheets (SDS) and proper labeling. Importers should verify if the specific chemical is listed on any national or international control lists and consult with regulatory bodies in both the exporting and importing countries.

How do major trade agreements like the USMCA or EU-Mercosur Agreement impact the import duties for HS 2931.41, and what is the typical duty rate reduction?

Major trade agreements often provide significant duty reductions or duty-free access for products classified under HS 2931.41. For instance, under the United States-Mexico-Canada Agreement (USMCA), qualifying goods originating from Mexico or Canada are typically eligible for duty-free treatment (0% ad valorem) when imported into the U.S., replacing the previous NAFTA benefits. Similarly, the EU has numerous FTAs (e.g., with Japan, South Korea, Canada) where 'non-halogenated organo-phosphorous derivatives' often receive preferential duty rates, frequently reducing the MFN rate of 6.00% to 0% ad valorem. While the EU-Mercosur Agreement is not yet fully ratified, if implemented, it would likely offer preferential rates for qualifying goods, potentially reducing the MFN duty rate for HS 2931.41. To claim these benefits, importers must ensure the goods meet the agreement's specific Rules of Origin and provide the necessary proof of origin, such as an origin declaration or certificate, as stipulated by the respective agreement.

What is the significance of the '25%' duty rate sometimes associated with HS 2931.41, and under what circumstances would it apply?

The '25%' duty rate often associated with HS 2931.41 typically refers to punitive or retaliatory tariffs, most notably those imposed by the United States under Section 301 of the Trade Act of 1974 against goods originating from specific countries, primarily China. These additional duties are applied on top of the normal MFN duty rate. For example, if a 'non-halogenated organo-phosphorous derivative' (HS 2931.41) originates from China and is subject to Section 301 tariffs, an importer into the U.S. would pay the normal MFN duty rate (e.g., 6.5% ad valorem) plus an additional 25% ad valorem duty, resulting in a total duty burden of 31.5% ad valorem. These tariffs are subject to change based on trade policy developments and exclusions. Importers must verify the country of origin and consult the latest official tariff schedules (e.g., USITC HTSUS General Notes) to determine if such additional duties apply to their specific imports.
