HS 293151 Halogenated organo-phosphorous derivatives
Quick Answer: HS code 293151 covers halogenated organo-phosphorous derivatives, which are organic chemical compounds containing both phosphorus and halogen atoms (like fluorine, chlorine, bromine, or iodine). These specialized chemicals are often used as intermediates in the production of pharmaceuticals, pesticides, flame retardants, and other industrial products. Importers and exporters should note 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 general Most Favored Nation (MFN) rate is 3.7% ad valorem, but significant preferential duty-free treatment is available under various Free Trade Agreements (e.g., A, AU, CL, KR). A punitive 25% duty may apply under specific trade measures. Always verify the specific origin and applicable trade agreements to optimize duty costs.

How to Classify This HS Code?
What products does HS 293151 cover?
This subheading covers halogenated organo-phosphorous derivatives, specifically those containing a phosphorus atom directly bonded to at least one carbon atom of an organic radical, and also containing one or more halogen atoms. As defined by the World Customs Organization's Harmonized System Nomenclature and reflected in the USITC Harmonized Tariff Schedule of the United States (HTSUS) and the EU TARIC, this includes complex organic compounds where phosphorus is an integral part of the molecular structure, and where halogen atoms (fluorine, chlorine, bromine, or iodine) are also present. These compounds are often used as intermediates in chemical synthesis, flame retardants, or plasticizers, exhibiting diverse applications due to their unique chemical properties.
What falls outside HS 293151?
The following products are excluded from HS 293151: organo-phosphorous derivatives that do not contain any halogen atoms, which would typically fall under other subheadings within Heading 2931 based on their specific chemical structure. Additionally, inorganic phosphides and phosphates, even if they contain halogens, are excluded as they are not "organo-phosphorous derivatives" and would be classified in Chapter 28. For example, triphenyl phosphate (a non-halogenated organo-phosphorous compound) would be classified elsewhere within Heading 2931, while sodium chlorophosphate (an inorganic compound) would fall under Chapter 28. Products that are mixtures, where the halogenated organo-phosphorous derivative is not the predominant component, might also be excluded if the mixture takes on the character of another product.
What are common classification mistakes for HS 293151?
A common error is misclassifying organo-phosphorous compounds that contain halogens but where the phosphorus atom is not directly bonded to a carbon atom, or where the halogen is not part of the organic radical. For instance, some inorganic phosphorus compounds containing halogens might be mistakenly placed here, violating the "organo-phosphorous" requirement. Another frequent mistake involves overlooking the "halogenated" criterion, leading to the incorrect inclusion of non-halogenated organo-phosphorous derivatives. Proper application of General Interpretative Rule (GRI) 1, which dictates classification by the terms of the headings and section or chapter notes, is crucial to avoid these errors, ensuring that both the organic and halogenated aspects are correctly identified in relation to the phosphorus atom.
How should importers classify products under HS 293151?
The correct procedure for classifying products under HS 293151 involves a meticulous review of the chemical structure and composition. Importers and customs brokers should first verify that the product is indeed an "organo-phosphorous derivative" by confirming the direct bond between phosphorus and carbon. Subsequently, they must confirm the presence of at least one halogen atom within the molecular structure. Consulting the chemical name, CAS number, and Safety Data Sheet (SDS) is essential to confirm these structural requirements. In cases of doubt, obtaining a binding tariff information (BTI) decision from the relevant customs authority (e.g., US Customs and Border Protection, EU national customs) or a ruling from the UK Border Force is highly recommended to ensure compliance and avoid potential penalties or delays.

FAQ
What are the typical import duty rates for products classified under HS 2931.51?
The Most Favored Nation (MFN) import duty rates for HS 2931.51, 'Halogenated organo-phosphorous derivatives,' generally range. For instance, the United States typically applies a 3.7% ad valorem duty rate under the Harmonized Tariff Schedule of the United States (HTSUS) General column 1. The European Union's TARIC database may show a common customs tariff of 6.50% ad valorem. The UK Global Tariff (UKGT) often lists a 6.00% ad valorem duty. It is crucial to verify the specific duty rate based on the country of import and origin using the official tariff schedules (e.g., USITC HTSUS, EU TARIC, UK Trade Tariff).
Which trade agreements offer preferential duty treatment for HS 2931.51, and what are the requirements?
Many trade agreements provide preferential duty treatment, often resulting in a 'Free' rate for HS 2931.51. For imports into the United States, preferential duty rates (often 'Free') are available under agreements such as the US-Australia Free Trade Agreement (AU), US-Bahrain FTA (BH), US-Chile FTA (CL), US-Colombia TPA (CO), US-Israel FTA (IL), US-Jordan FTA (JO), US-Korea FTA (KR), US-Morocco FTA (MA), US-Oman FTA (OM), US-Panama TPA (PA), US-Peru TPA (PE), and the Singapore FTA (SG). To claim preferential duty, importers must ensure the goods meet the Rules of Origin specified in the respective agreement and possess valid documentation, such as a Certificate of Origin or a declaration from the producer/exporter, confirming origin.
What are the key classification criteria for 'Halogenated organo-phosphorous derivatives' under HS 2931.51?
HS 2931.51 specifically covers 'Halogenated organo-phosphorous derivatives.' The primary classification criteria revolve around the chemical structure: the compound must contain both a halogen atom (e.g., fluorine, chlorine, bromine, iodine) and a phosphorus atom, and it must be an organic compound. This excludes inorganic phosphorus compounds or organic compounds lacking either a halogen or phosphorus. Importers and customs brokers should refer to the Explanatory Notes to Chapter 29 of the Harmonized System, particularly those pertaining to heading 29.31, for detailed guidance on the scope and interpretation of 'organo-phosphorous compounds' and 'derivatives' within this context.
Are there any specific documentation requirements or regulatory considerations for importing products under HS 2931.51?
Beyond standard customs documentation (commercial invoice, packing list, bill of lading/air waybill), importers of HS 2931.51 products, which are chemical compounds, may face additional regulatory requirements depending on the country of import and the specific chemical. These could include Safety Data Sheets (SDS) for hazardous materials, compliance with chemical inventory regulations (e.g., TSCA in the US, REACH in the EU, K-REACH in Korea), and potentially import licenses or permits if the substance is controlled or restricted. It is essential to verify national chemical control laws and regulations applicable to the specific derivative being imported to ensure full compliance.
Can products under HS 2931.51 be subject to anti-dumping or countervailing duties (AD/CVD)?
Yes, products classified under HS 2931.51, like any other imported good, can be subject to anti-dumping or countervailing duties (AD/CVD) if investigations by importing countries (e.g., the U.S. Department of Commerce or the European Commission) determine that specific products from certain countries are being dumped or unfairly subsidized. For example, while not currently active for all products under 2931.51, a 25% duty rate could represent an AD/CVD measure. Importers must regularly check official trade remedy databases (e.g., U.S. International Trade Administration, EU Trade Defence website) for any active AD/CVD orders that might apply to their specific product and country of origin, as these duties are applied in addition to normal customs duties.
