HS 293152 Propylphosphonic dichloride
Quick Answer: HS code 2931.52 specifically covers Propylphosphonic dichloride, a distinct organo-phosphorus compound used primarily as a chemical intermediate in various synthesis processes, including pharmaceuticals and specialty chemicals. Importers and exporters should note the varying duty rates across major jurisdictions: the UK applies a 6.00% ad valorem duty, while the EU TARIC system lists 6.50%. For the United States, the general Most Favored Nation (MFN) duty rate is 3.7% ad valorem, though numerous Free Trade Agreement (FTA) partners (e.g., Australia, Korea, Mexico, Singapore) benefit from a "Free" duty rate. Additionally, goods from certain countries may be subject to Section 301 duties, currently at 25%. Accurate classification is crucial to leverage preferential trade agreements and avoid penalties.

How to Classify This HS Code?
What products does HS 293152 cover?
This subheading covers Propylphosphonic dichloride, a specific organo-phosphorus compound. According to the Harmonized System Nomenclature, specifically Chapter 29, Heading 2931 encompasses "Other organo-inorganic compounds." Subheading 2931.52 precisely identifies Propylphosphonic dichloride, a chemical compound with the formula CH₃CH₂CH₂P(O)Cl₂. This classification is consistent across major tariff schedules, including the USITC Harmonized Tariff Schedule (HTSUSA) and the EU TARIC, which both list this specific chemical under this 8-digit code, ensuring uniform application in international trade for this distinct chemical entity.
What falls outside HS 293152?
The following products are excluded from HS 293152: other phosphonic dichlorides, such as methylphosphonic dichloride (HS 2931.51) or phenylphosphonic dichloride (HS 2931.59), which are distinct chemical compounds despite their structural similarities. Additionally, other organo-phosphorus compounds that are not phosphonic dichlorides, or those that do not contain a propyl group, would be classified elsewhere within Heading 2931 or other relevant headings in Chapter 29, depending on their specific chemical structure and functional groups. For instance, simple phosphorus halides without organic components would fall under Chapter 28, not Chapter 29, as they are inorganic compounds.
What are common classification mistakes for HS 293152?
A common error is misidentifying the specific alkyl group attached to the phosphonic dichloride moiety, leading to incorrect classification within Heading 2931. For example, confusing propylphosphonic dichloride with isopropylphosphonic dichloride or butylphosphonic dichloride, which would fall under HS 2931.59 ("Other"), is a frequent mistake. This often occurs due to insufficient chemical analysis or a lack of precise product documentation. Adherence to 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, is crucial. Importers must ensure the chemical name and structure precisely match "Propylphosphonic dichloride" to avoid misclassification.
How should importers classify products under HS 293152?
The correct procedure for classifying Propylphosphonic dichloride involves verifying the precise chemical identity of the product. Importers and customs brokers should obtain a Certificate of Analysis (CoA) or a Safety Data Sheet (SDS) that clearly states the chemical name as "Propylphosphonic dichloride" and provides its Chemical Abstracts Service (CAS) registry number, which for this compound is 1498-58-4. This documentation should be cross-referenced with the WCO Harmonized System Explanatory Notes for Chapter 29 and the specific tariff schedule (e.g., USITC HTSUSA or EU TARIC) to confirm that the product description aligns exactly with subheading 2931.52. Any ambiguity requires consultation with a customs expert or the relevant customs authority to ensure accurate and compliant classification.

FAQ
What is the Most Favored Nation (MFN) import duty rate for Propylphosphonic dichloride (HS 2931.52) in key markets?
The MFN (Most Favored Nation) import duty rates for Propylphosphonic dichloride (HS 2931.52) vary by country. For example, the United States generally applies a duty rate of 3.7% ad valorem under the Harmonized Tariff Schedule of the United States (HTSUS). The European Union's TARIC database indicates a common customs duty of 6.50% ad valorem. The UK Global Tariff also lists a 6.50% ad valorem duty. Importers should always verify the current rate with the official customs tariff of the importing country, such as the USITC HTSUS, EU TARIC, or UK Trade Tariff.

What are the key classification criteria for Propylphosphonic dichloride under HS 2931.52?
Propylphosphonic dichloride is classified under HS 2931.52 as an 'Organo-phosphorus compounds' specifically within the broader category of 'Other organo-inorganic compounds'. The classification hinges on its chemical structure: it is an organic compound containing phosphorus directly bonded to carbon, and it is a dichloride. Chapter 29 of the Harmonized System (HS) covers organic chemicals, and heading 29.31 specifically includes other organo-inorganic compounds. The subheadings further delineate based on the specific type of organo-inorganic compound. Importers should ensure the chemical name, CAS number, and molecular structure precisely match the description for 2931.52 to avoid misclassification.
What documentation is typically required for importing Propylphosphonic dichloride (HS 2931.52)?
Standard import documentation for Propylphosphonic dichloride (HS 2931.52) includes a commercial invoice, packing list, bill of lading or air waybill, and a customs declaration form. For claiming preferential duty rates, a Certificate of Origin (e.g., FTA certificate, GSP Form A) is essential. Additionally, as a chemical substance, a Material Safety Data Sheet (MSDS/SDS) is often required by regulatory bodies for safety and environmental compliance. Depending on the specific end-use or national regulations, further permits or licenses from chemical control authorities may be necessary. Customs brokers can assist in ensuring all required documentation is complete and accurate.
Could Propylphosphonic dichloride (HS 2931.52) be subject to anti-dumping duties or other special measures?
While there are no widespread anti-dumping or countervailing duties specifically targeting Propylphosphonic dichloride (HS 2931.52) at present, it is crucial for importers to remain vigilant. Trade remedy measures can be imposed on specific products from particular countries if dumping or subsidization is found to cause material injury to a domestic industry. Importers should regularly check their respective customs authority's official publications (e.g., U.S. Federal Register, EU Official Journal, UK Trade Tariff notices) for any ongoing investigations or new duties that might affect this HS code or its country of origin. Additionally, certain chemicals may be subject to export controls or import restrictions due to their potential dual-use applications, though this is less common for Propylphosphonic dichloride itself.
