HS 293729 Other
Quick Answer: HS code 293729, "Other," encompasses a diverse range of hormones, their derivatives, and structural analogues not specified elsewhere within heading 2937. This includes various synthetic and natural hormonal substances crucial for pharmaceutical and research applications. For importers and exporters, understanding the specific product is paramount due to varying tariff treatments. The UK and EU generally apply a 0.00% ad valorem duty rate for products classified under this code. In contrast, the US tariff schedule for 293729 is more granular, featuring multiple subheadings with rates ranging from "Free" to complex compound duties such as "15.4¢/kg + 49% ad valorem." Importers should verify the exact 10-digit US HTS code for their specific product to determine the applicable duty. Due to the sensitive nature of these products, regulatory compliance beyond customs duties, such as FDA or EMA approvals, is often a significant consideration.

How to Classify This HS Code?
What products does HS 293729 cover?
This subheading covers hormones, their derivatives, and structural analogues, specifically excluding those of subheadings 2937.11 through 2937.23, and 2937.29. This includes a broad range of synthetic and natural steroid hormones not elsewhere specified, such as certain corticosteroids, estrogens, and androgens, provided they are chemically defined and fall within the scope of Heading 2937 as defined by the World Customs Organization (WCO) Harmonized System Explanatory Notes. Examples include various synthetic steroid intermediates or less common steroid hormones not specifically enumerated in other 2937 subheadings, as reflected in the USITC Harmonized Tariff Schedule and EU TARIC classifications.
What falls outside HS 293729?
The following products are excluded from HS 293729: pituitary (anterior) or similar hormones (2937.11), corticosteroid hormones, their derivatives and structural analogues (2937.21), halogenated derivatives of corticosteroid hormones (2937.22), and estrogens and progestins (2937.23). Additionally, medicaments containing hormones, even if composed solely of a single hormone, are generally excluded and classified in Chapter 30, specifically Heading 3003 or 3004, depending on whether they are put up in measured doses or for retail sale. For instance, a pure, chemically defined steroid hormone in bulk form would fall under 293729, but the same hormone formulated into tablets for therapeutic use would be classified as a medicament.
What are common classification mistakes for HS 293729?
A common error is misclassifying medicaments containing hormones under Heading 2937, rather than Chapter 30. Importers often overlook the distinction between chemically defined pure substances and pharmaceutical preparations. Another frequent mistake involves incorrectly assigning specific steroid hormones to 293729 when a more specific subheading (e.g., 2937.21 for corticosteroids or 2937.23 for estrogens) exists. This violates General Rule of Interpretation (GRI) 3(a), which prioritizes the most specific heading. Furthermore, failing to distinguish between structural analogues and actual hormones can lead to misclassification, requiring careful chemical analysis and reference to the WCO Explanatory Notes for precise definitions.
How should importers classify products under HS 293729?
The correct procedure for classifying products under HS 293729 involves a systematic approach. First, confirm the product is a chemically defined hormone, derivative, or structural analogue. Second, meticulously review all other subheadings within Heading 2937 (2937.11, 2937.21, 2937.22, 2937.23) to ensure the product is not more specifically described elsewhere, applying GRI 3(a). Third, verify that the product is not a medicament or pharmaceutical preparation, which would direct classification to Chapter 30. Importers and customs brokers should consult the WCO HS Explanatory Notes for Heading 2937, along with the USITC Harmonized Tariff Schedule and EU TARIC for specific national interpretations and rulings, to ensure accurate and compliant classification.

FAQ
What is the import duty rate for products classified under HS 2937.29 in major markets?
The Most Favored Nation (MFN) duty rates for HS 2937.29 ('Other' steroid hormones, their derivatives and structural analogues) vary significantly by importing country. For example, as of current tariffs:
- United States (USITC HTSUS): The MFN (General) duty rate is 0.00% ad valorem.
- European Union (TARIC): The MFN duty rate is 0.00% ad valorem.
- United Kingdom (UK Trade Tariff): The MFN duty rate is Free (0.00% ad valorem).
However, it is crucial for importers to verify the specific duty rate applicable to their country of origin and destination via the official tariff databases (e.g., USITC HTSUS, EU TARIC, UK Trade Tariff) as preferential rates may apply under various trade agreements.
What are the key classification criteria for products under HS 2937.29, and how does it differ from other subheadings in 2937?
HS 2937.29 covers 'Other' steroid hormones, their derivatives and structural analogues, meaning those not specifically provided for in subheadings 2937.21 through 2937.23 (e.g., Cortisone, hydrocortisone, prednisone, prednisolone, their halogenated derivatives; Oestrogens and progestogens; Androgens and their derivatives). The primary classification criterion for 2937.29 is that the substance must be a steroid hormone, a derivative thereof, or a structural analogue, and it must not be explicitly named or covered by a more specific subheading within 2937.2. Importers and customs brokers must ensure the chemical structure and primary function align with the definition of a steroid hormone or its analogue, and critically, confirm it is not listed elsewhere in the chapter or heading. Reference to the Harmonized System Explanatory Notes for Heading 29.37 is essential for precise interpretation.
What common trade agreements might offer preferential duty rates for goods classified under HS 2937.29?
While the MFN rates for HS 2937.29 are often 0.00% or Free in major markets, preferential trade agreements can still be relevant for other duties or for future rate changes. For instance:
- United States: Goods originating from countries with Free Trade Agreements (FTAs) like USMCA (Canada/Mexico), CAFTA-DR, or agreements with Australia, Korea, etc., would typically also enter duty-free.
- European Union: Products from countries with preferential agreements (e.g., GSP, agreements with UK, Japan, Canada, etc.) would also generally benefit from 0.00% duty.
- United Kingdom: Similar to the EU, the UK has its own network of FTAs and trade agreements (e.g., with the EU, Japan, Australia) that would ensure duty-free entry.
Importers should always check the specific rules of origin and documentation requirements (e.g., Certificate of Origin) under the relevant trade agreement to claim preferential treatment, even if the MFN rate is already zero.
Are there any specific documentation requirements or regulatory considerations for importing products under HS 2937.29?
Yes, beyond standard customs documentation (commercial invoice, packing list, bill of lading/air waybill), products under HS 2937.29, being steroid hormones or their analogues, are often subject to stringent regulatory controls due to their pharmaceutical or biological activity. Importers should be prepared for:
- FDA (USA) / EMA (EU) / MHRA (UK) Requirements: If the product is intended for pharmaceutical use, it will likely require pre-market approval, import licenses, and compliance with Good Manufacturing Practices (GMP).
- Chemical Analysis/Certificates of Analysis (CoA): Customs authorities may request CoAs to verify the exact chemical composition and purity.
- End-Use Declarations: In some cases, an end-use declaration may be required, especially if the product has potential dual-use applications or is subject to specific controls.
- Controlled Substances: While not all substances in 2937.29 are controlled, some steroid hormones can be. Importers must verify if their specific product falls under national controlled substance regulations (e.g., DEA in the US) requiring additional permits and strict record-keeping. It is critical to consult with regulatory affairs specialists and customs brokers experienced in pharmaceutical imports.
