How to Classify This HS Code?
What products does HS 293492 cover?
This subheading covers "Other fentanyls and their derivatives," specifically referring to chemical compounds structurally related to fentanyl that are not elsewhere specified within the Harmonized System. According to the World Customs Organization (WCO) Harmonized System Nomenclature and further defined by national tariffs like the USITC Harmonized Tariff Schedule of the United States (HTSUS) and the EU TARIC, this includes various synthetic opioids derived from 4-anilidopiperidine, such as carfentanil, sufentanil, alfentanil, and remifentanil, which are potent analgesics and controlled substances. These substances are characterized by their specific chemical structures and pharmacological properties, primarily used in medicine as anesthetics and analgesics, but also subject to strict regulatory controls due to their potential for abuse.
What falls outside HS 293492?
The following products are excluded from HS 293492: fentanyl itself, which is specifically classified under HS 2934.91.00.00. Additionally, other heterocyclic compounds with nitrogen hetero-atom(s) only, which do not possess the specific chemical structure or pharmacological profile of fentanyl derivatives, would be classified elsewhere within Chapter 29, such as under other subheadings of 2934, or even in other chapters if they are formulated into medicaments (e.g., Chapter 30). For instance, a finished pharmaceutical product containing a fentanyl derivative in measured doses for therapeutic use would typically fall under Chapter 30, "Pharmaceutical products," rather than solely as a bulk chemical under 293492.
What are common classification mistakes for HS 293492?
A common error is misclassifying fentanyl itself under 293492 instead of its specific subheading, 293491.00.00. Another frequent mistake involves classifying finished pharmaceutical preparations containing fentanyl derivatives under 293492, when they should properly be classified under Chapter 30, specifically under headings like 3004, if they are medicaments consisting of mixed or unmixed products for therapeutic or prophylactic uses, put up in measured doses or in forms or packings for retail sale. This error often arises from neglecting General Interpretative Rule (GRI) 3(a), which prioritizes specific descriptions over general ones, and GRI 3(b), which addresses mixtures and composite goods, often leading to classification in Chapter 30 for formulated medicines.
How should importers classify products under HS 293492?
The correct procedure for classifying products under HS 293492 involves a meticulous review of the chemical structure and composition of the substance. Importers and customs brokers must first confirm that the product is indeed a fentanyl derivative and not fentanyl itself (which falls under 293491). They should then ensure it is not a finished medicament in measured doses or retail packaging, which would direct classification to Chapter 30. Consulting the WCO Explanatory Notes for Heading 2934 and relevant national tariff schedules (e.g., USITC HTSUS, EU TARIC) is crucial. Furthermore, obtaining a detailed chemical analysis report or a Certificate of Analysis (CoA) from the manufacturer, confirming the exact chemical name and structure, is highly recommended to support the classification decision and ensure compliance with all applicable regulations, including those pertaining to controlled substances.

FAQ
What are the standard Most Favored Nation (MFN) import duty rates for HS code 2934.92, 'Other fentanyls and their derivatives'?
The MFN (Most Favored Nation) import duty rates for HS code 2934.92 can vary significantly by importing country. For example, the United States generally applies a duty rate of 6.5% ad valorem under the Harmonized Tariff Schedule of the United States (HTSUS) for goods classified under 2934.92.00. In contrast, the European Union's TARIC database often shows a 0.00% ad valorem duty rate for this classification. Importers should always consult the specific tariff schedule of the importing country (e.g., USITC HTSUS, EU TARIC, UK Trade Tariff) for the definitive MFN rate applicable at the time of importation.
Are there any preferential duty rates or free trade agreement benefits available for HS 2934.92?
Yes, preferential duty rates, including duty-free treatment, are often available for HS 2934.92 under various free trade agreements (FTAs) or special programs, provided the goods meet the respective rules of origin. For instance, the United States offers 'Free' duty rates for imports from countries with which it has FTAs, 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). The specific program indicators (e.g., 'A', 'D', 'E', 'K', 'P', 'S') denote the applicable trade agreement or preference program. Importers must ensure they have the proper documentation, such as a certificate of origin, to claim these preferential rates.
What are the key classification criteria for determining if a substance falls under HS 2934.92?
HS code 2934.92 specifically covers 'Other fentanyls and their derivatives' within Chapter 29, which deals with organic chemicals. The primary classification criteria revolve around the chemical structure and function of the substance. Goods classified here must be heterocyclic compounds with only oxygen, nitrogen, or sulfur hetero-atoms, and specifically be fentanyl or its chemical derivatives not elsewhere specified in the tariff. This classification is precise and requires a detailed chemical analysis of the substance's molecular structure to confirm it is a fentanyl derivative and not covered by a more specific subheading within Chapter 29 or elsewhere in the Harmonized System. Reference to the Explanatory Notes of the WCO Harmonized System for Chapter 29 and heading 29.34 is crucial for accurate classification.
What specific documentation and regulatory requirements are typically associated with importing substances classified under HS 2934.92?
Due to the nature of substances classified under HS 2934.92 (fentanyl and its derivatives), importers face stringent documentation and regulatory requirements. These substances are typically controlled under international conventions (e.g., UN Single Convention on Narcotic Drugs of 1961, Convention on Psychotropic Substances of 1971) and national drug control laws. Importers will generally need: 1) Import licenses or permits issued by the relevant national drug enforcement or health authorities (e.g., DEA in the US, national health ministries in the EU). 2) A detailed chemical analysis or certificate of analysis for the substance. 3) Commercial invoice, packing list, and bill of lading/air waybill. 4) Compliance with specific labeling, packaging, and storage requirements. Failure to comply with these regulations can result in severe penalties, including seizure of goods and criminal prosecution. Importers should consult with legal counsel specializing in controlled substances and the relevant national regulatory bodies well in advance of any importation.
Are there any specific anti-dumping or countervailing duties (AD/CVD) that could apply to HS 2934.92?
While general MFN and preferential duty rates are common for HS 2934.92, the application of specific Anti-Dumping (AD) or Countervailing Duties (CVD) is product- and country-specific and less common for highly specialized pharmaceutical intermediates or controlled substances like fentanyl derivatives. AD/CVD measures are typically imposed on goods found to be dumped or subsidized, causing material injury to a domestic industry. Importers should regularly check the official trade remedy websites of the importing country (e.g., US Department of Commerce, EU Commission Trade Defence) for any active AD/CVD orders that might apply to specific chemical products originating from particular countries, as these duties can significantly increase import costs. It is rare, but not impossible, for such measures to be applied to specific chemical compounds if a domestic industry exists and is deemed injured.
