HS 293722 Halogenated derivatives of corticosteroidal hormones
Quick Answer: HS code 2937.22 covers halogenated derivatives of corticosteroidal hormones, which are synthetic versions of steroid hormones modified with halogen atoms (like fluorine, chlorine, bromine, or iodine). These compounds are primarily used as active pharmaceutical ingredients (APIs) in medications for their anti-inflammatory and immunosuppressive properties. For importers and exporters, understanding the specific halogenated derivative is crucial for accurate classification. Duty rates vary significantly: the UK and EU generally apply a 0.00% ad valorem duty. In the US, the Most Favored Nation (MFN) duty rate is Free, but Section 301 tariffs may apply, imposing an additional 25% ad valorem duty on goods of Chinese origin. Importers should verify the country of origin and consult the USITC Harmonized Tariff Schedule for current Section 301 applicability.

How to Classify This HS Code?
What products does HS 293722 cover?
This subheading covers halogenated derivatives of corticosteroidal hormones, which are complex organic chemical compounds primarily used for their anti-inflammatory and immunosuppressive properties. Specifically, it encompasses synthetic corticosteroids where one or more hydrogen atoms have been replaced by a halogen atom (fluorine, chlorine, bromine, or iodine). Examples include betamethasone, dexamethasone, and fluticasone, which are widely utilized in pharmaceutical preparations. The classification is based on the chemical structure as defined by the World Customs Organization's Harmonized System Nomenclature and further detailed in explanatory notes from the US International Trade Commission (USITC) and the EU TARIC system, ensuring precise identification of these active pharmaceutical ingredients.
What falls outside HS 293722?
The following products are excluded from HS 293722: non-halogenated corticosteroidal hormones, which would typically fall under HS 293721 (e.g., hydrocortisone, prednisone) or other relevant subheadings within 2937 if they are not corticosteroids. Additionally, pharmaceutical preparations containing these halogenated derivatives, but formulated for retail sale or specific therapeutic uses, are generally classified in Chapter 30, specifically under headings like 3003 or 3004, depending on their form and presentation. For instance, a cream containing betamethasone would be classified in Chapter 30, not as the bulk active ingredient in 293722, as per the General Interpretative Rules (GRI) for the Harmonized System.
What are common classification mistakes for HS 293722?
A common error is misclassifying pharmaceutical preparations containing halogenated corticosteroidal hormones as the bulk active ingredient under HS 293722, rather than in Chapter 30. Importers sometimes overlook GRI 3(b), which prioritizes classification by essential character for mixtures or composite goods, or GRI 6, which applies GRI 1-5 mutatis mutandis to subheadings. Another frequent mistake involves failing to distinguish between halogenated and non-halogenated corticosteroidal hormones, leading to incorrect placement within subheadings 293721 or 293722. Accurate chemical identification and understanding the specific definition of "derivatives" are crucial to avoid these errors and ensure compliance with customs regulations.
How should importers classify products under HS 293722?
The correct procedure for classifying products under HS 293722 involves a meticulous review of the product's chemical structure and intended form. Importers and customs brokers must first confirm that the substance is indeed a corticosteroidal hormone and that it contains at least one halogen atom in its molecular structure, referencing chemical analysis reports or Certificates of Analysis. Secondly, it is imperative to ensure the product is in its bulk, unformulated state, not a finished pharmaceutical preparation for retail or therapeutic use, which would direct classification to Chapter 30. Consulting the WCO Explanatory Notes for Heading 2937 and official rulings from customs authorities like the USITC or EU TARIC is highly recommended to confirm the precise chemical definition and application of this subheading.

FAQ
What are the Most Favored Nation (MFN) duty rates for HS code 2937.22 (Halogenated derivatives of corticosteroidal hormones) in major markets?
The MFN duty rates for products classified under HS 2937.22 can vary significantly by importing country. For example, the United States generally applies a 'Free' rate (0.00% ad valorem) for MFN imports under HTSUS subheading 2937.22.00. The European Union's TARIC database also indicates a 0.00% ad valorem MFN duty rate for this subheading. However, other countries may apply different rates. Importers should always consult the specific tariff schedule of the destination country, such as the USITC Harmonized Tariff Schedule, EU TARIC, or the UK Trade Tariff, for the most accurate and up-to-date information.
What are the key classification criteria for 'Halogenated derivatives of corticosteroidal hormones' under HS 2937.22?
Classification under HS 2937.22 requires the product to be a corticosteroidal hormone that has undergone halogenation. This means a halogen atom (fluorine, chlorine, bromine, or iodine) must be chemically bonded to the corticosteroid structure. The World Customs Organization (WCO) Explanatory Notes to Chapter 29 provide guidance, emphasizing that these are chemically defined organic compounds. Importers must ensure their product's chemical structure precisely matches this description, distinguishing it from non-halogenated corticosteroidal hormones (e.g., HS 2937.21) or other hormone derivatives. A Certificate of Analysis (CoA) or chemical structure elucidation is often crucial for accurate classification.
Are there any preferential duty rates or trade agreements that commonly apply to HS 2937.22, potentially reducing import duties?
Yes, preferential duty rates are often available for HS 2937.22 under various free trade agreements (FTAs) or Generalized System of Preferences (GSP) schemes. For instance, imports into the United States from countries party to agreements like the USMCA (United States-Mexico-Canada Agreement), CAFTA-DR (Dominican Republic-Central America FTA), or various GSP beneficiary countries may qualify for a 0.00% preferential duty rate, provided the goods meet the specific Rules of Origin. Similarly, the EU has numerous FTAs (e.g., with Japan, Korea, Canada) and GSP arrangements that could offer preferential treatment. Importers should check the specific agreement's origin rules and ensure they have the necessary documentation, such as a Certificate of Origin, to claim preferential tariffs.
What specific documentation is typically required for customs clearance of 'Halogenated derivatives of corticosteroidal hormones' under HS 2937.22?
Beyond standard shipping documents (commercial invoice, packing list, bill of lading/air waybill), importers of products under HS 2937.22 may need additional documentation due to the nature of these chemical compounds. This often includes a Certificate of Analysis (CoA) detailing the chemical composition and purity, a Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS), and potentially a manufacturer's declaration confirming the chemical identity and halogenation. If claiming preferential duty rates, a valid Certificate of Origin (e.g., EUR.1, NAFTA/USMCA Certificate of Origin, GSP Form A) is mandatory. Depending on the specific corticosteroid and its end-use, health or pharmaceutical regulatory approvals (e.g., FDA import alerts, EMA authorizations) might also be required by the importing country's authorities.
Could HS 2937.22 products be subject to anti-dumping or countervailing duties, or specific import restrictions?
While HS 2937.22 generally covers a range of specialized pharmaceutical intermediates or active pharmaceutical ingredients (APIs), it is always possible for specific products within this classification to become subject to anti-dumping (AD) or countervailing duties (CVD) if investigations determine unfair trade practices. Importers should regularly check the trade remedies databases of the importing country (e.g., US Department of Commerce, EU Commission Trade Defence) for any active AD/CVD orders related to specific halogenated corticosteroidal hormones or their country of origin. Additionally, due to their nature as hormones, these products may be subject to specific import restrictions or licensing requirements related to pharmaceutical control, precursor chemicals, or environmental regulations in certain jurisdictions. Consulting with a customs broker specializing in pharmaceutical imports is advisable.
