HS 293153 O-(3-chloropropyl) O-[4-nitro-3-(trifluoromethyl)phenyl] methylphosphonothionate
Quick Answer: HS code 293153 specifically covers O-(3-chloropropyl) O-[4-nitro-3-(trifluoromethyl)phenyl] methylphosphonothionate, a complex organo-phosphorus compound. This chemical is primarily used as an intermediate in the synthesis of certain pesticides and other specialty chemicals. Importers and customs brokers should note the varying duty rates: the UK applies a 6.00% ad valorem duty, the EU a 6.50% ad valorem duty, and the US a 3.7% ad valorem duty under the Most Favored Nation (MFN) rate. However, the US offers duty-free treatment under various Free Trade Agreements (FTAs) for eligible goods from countries like Australia, Korea, and Singapore. Conversely, a 25% ad valorem duty applies under the US Column 2 rate. Accurate classification is crucial to leverage preferential tariffs and avoid penalties.

How to Classify This HS Code?
What products does HS 293153 cover?
This subheading covers the specific chemical compound O-(3-chloropropyl) O-[4-nitro-3-(trifluoromethyl)phenyl] methylphosphonothionate. This precise chemical is an organo-phosphorus derivative, characterized by its specific molecular structure as defined in the Harmonized System Nomenclature, specifically under Heading 2931 for other organo-inorganic compounds. The WCO Explanatory Notes for Chapter 29 emphasize the importance of exact chemical nomenclature for classification, ensuring that only this distinct compound, with its unique chloropropyl, nitrophenyl, and trifluoromethyl substituents on a methylphosphonothionate backbone, is classified here. Both the USITC Harmonized Tariff Schedule (HTSUS) and the EU TARIC system align with this precise definition, leaving no room for broader interpretations.
What falls outside HS 293153?
The following products are excluded from HS 293153: any other organo-phosphorus compounds that do not precisely match the chemical structure of O-(3-chloropropyl) O-[4-nitro-3-(trifluoromethyl)phenyl] methylphosphonothionate. For instance, similar compounds with different alkyl or aryl groups, or variations in the halogen or nitro substituents, would be classified elsewhere, typically under other subheadings within Heading 2931 or even other headings in Chapter 29, depending on their specific chemical characteristics. For example, a compound like O-(2-chloroethyl) O-[4-nitro-3-(trifluoromethyl)phenyl] methylphosphonothionate, despite its close resemblance, would not fall under 293153 due to the differing chloropropyl chain length. Similarly, mixtures containing this compound would generally be classified under different headings, often in Chapter 38, if they constitute preparations.
What are common classification mistakes for HS 293153?
A common error is misclassifying closely related organo-phosphorus compounds under HS 293153 due to slight structural differences, violating General Interpretative Rule (GRI) 1, which dictates that classification is determined according to the terms of the headings and any relative section or chapter notes. Importers might incorrectly assume that a compound with a similar name or function, but a different chemical structure, belongs here. For example, confusing a related phosphonothionate with a different substituent group for the specifically named compound in 293153 is a frequent mistake. Another error involves classifying mixtures or formulations containing O-(3-chloropropyl) O-[4-nitro-3-(trifluoromethyl)phenyl] methylphosphonothionate under this subheading, when such preparations should typically be classified under Chapter 38, specifically Heading 3808 if they are pesticides, or other relevant headings based on their composition and intended use, as per GRI 3(b).
How should importers classify products under HS 293153?
The correct procedure for classifying products under HS 293153 requires meticulous attention to the precise chemical name and structure. Importers and customs brokers must first verify that the product is indeed O-(3-chloropropyl) O-[4-nitro-3-(trifluoromethyl)phenyl] methylphosphonothionate, using chemical analysis reports, Certificates of Analysis (CoA), and Safety Data Sheets (SDS) from the manufacturer. It is crucial to cross-reference the Chemical Abstracts Service (CAS) number, if available, against official databases to confirm the exact compound. If the product is a pure, unmixed form of this specific chemical, then classification under 293153 is appropriate, adhering strictly to GRI 1. For any doubts or if the product is a mixture or preparation, seeking a binding ruling from the relevant customs authority (e.g., CBP in the US, HMRC in the UK, or national customs authorities in the EU) is highly recommended to ensure compliance and avoid potential penalties.

FAQ
What is the Most Favored Nation (MFN) import duty rate for O-(3-chloropropyl) O-[4-nitro-3-(trifluoromethyl)phenyl] methylphosphonothionate (HS 293153) in key markets?
The MFN (Most Favored Nation) import duty rate for HS 293153, O-(3-chloropropyl) O-[4-nitro-3-(trifluoromethyl)phenyl] methylphosphonothionate, varies by importing country. For instance, the general MFN duty rate in the United States is 6.50% ad valorem. In the European Union (EU TARIC), the MFN duty rate is typically 6.00% ad valorem. The United Kingdom Global Tariff (UKGT) also applies a 6.00% ad valorem MFN rate. Importers should always verify the current applicable rate with the customs authority of the importing country or through official tariff databases such as the USITC Tariff Database, EU TARIC, or UK Trade Tariff.
Are there any preferential duty rates available for HS 293153 under common free trade agreements?
Yes, preferential duty rates, including 'Free' (0% ad valorem), are available for HS 293153 under various Free Trade Agreements (FTAs) and Generalized System of Preferences (GSP) programs, provided the goods meet the respective Rules of Origin. For example, imports into the United States from countries party to agreements 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. Similarly, the EU and UK have extensive networks of preferential agreements. Importers must ensure they have the correct origin documentation (e.g., Certificate of Origin) to claim these preferential rates. Consult the specific FTA text or customs regulations for detailed origin requirements.
What are the key classification criteria for O-(3-chloropropyl) O-[4-nitro-3-(trifluoromethyl)phenyl] methylphosphonothionate under HS 2931.53?
HS 2931.53 specifically covers 'Organo-phosphorus derivatives of thiocarbamic acids and their salts; other organo-phosphorus compounds.' The classification of O-(3-chloropropyl) O-[4-nitro-3-(trifluoromethyl)phenyl] methylphosphonothionate under this subheading is based on its chemical structure as an organo-phosphorus compound containing a thiophosphate group. The presence of phosphorus directly bonded to carbon (organo-phosphorus) and the specific chemical structure, including the thiocarbonyl (C=S) or thiophosphate (P=S) moiety, are critical. This product falls under Chapter 29, which covers 'Organic chemicals,' due to its defined chemical structure and purity. Importers should ensure the chemical name, CAS number, and structural formula align with the description for accurate classification, referencing the Explanatory Notes to the Harmonized System for Chapter 29.
What specific documentation is required for importing HS 293153, particularly for claiming preferential duty rates?
Standard import documentation for HS 293153 includes a commercial invoice, packing list, bill of lading or air waybill, and potentially a Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) due to its chemical nature. To claim preferential duty rates under a Free Trade Agreement (FTA), a valid Certificate of Origin (e.g., Form A for GSP, specific FTA certificates like the USMCA Certificate of Origin, or a self-certification by the exporter) is mandatory. This document certifies that the goods meet the Rules of Origin criteria of the respective agreement. Failure to provide correct and complete origin documentation will result in the application of the higher MFN duty rate. Additionally, depending on the end-use and specific chemical properties, other agency requirements (e.g., EPA, FDA in the US) or import licenses might be necessary, which should be verified prior to shipment.
