HS 293711 Polypeptide hormones, protein hormones and glycoprotein hormones, their derivatives and structural analogues
Quick Answer: HS code 293711 encompasses polypeptide, protein, and glycoprotein hormones, along with their derivatives and structural analogues. This classification covers a range of biologically active substances crucial in pharmaceuticals and research, such as insulin, growth hormones, and various synthetic analogues used in medical treatments. For importers and exporters, understanding the specific product composition is vital for accurate classification. Across major jurisdictions, duty rates vary. The United Kingdom and the European Union generally apply a 0.00% ad valorem duty rate to products classified under 293711. In the United States, while many products within this code are "Free," certain items may face a 10% ad valorem duty. Importers should verify the specific subheading and product details against the US Harmonized Tariff Schedule (HTSUS) to confirm the applicable rate. Given the sensitive nature of these products, compliance with health, safety, and regulatory standards (e.g., FDA, EMA) is paramount in addition to customs requirements.

How to Classify This HS Code?
What products does HS 293711 cover?
This subheading covers polypeptide hormones, protein hormones, and glycoprotein hormones, along with their derivatives and structural analogues. These are complex organic compounds, typically produced by living organisms, that act as chemical messengers. Examples include insulin, glucagon, growth hormone (somatotropin), and erythropoietin. The classification is guided by the Harmonized System Explanatory Notes for Heading 2937, which specifies these biologically active substances. The USITC Harmonized Tariff Schedule (HTSUS) and the EU TARIC system both align with this WCO definition, focusing on the chemical structure and biological function of these specific types of hormones.
What falls outside HS 293711?
The following products are excluded from HS 293711: steroid hormones (e.g., cortisol, testosterone, estrogen), which are classified under HS 2937.2X; amino-acid derivatives with hormone functions (e.g., adrenaline, thyroxine), which fall under HS 2937.90; and prostaglandins, thromboxanes, and leukotrienes, which are also classified under HS 2937.90. Additionally, diagnostic reagents containing these hormones, but prepared for specific diagnostic uses, are generally classified in Chapter 38, specifically subheading 3822.00, if they constitute prepared diagnostic reagents. Live animal glands and other organs containing hormones are classified in Chapter 5, not Chapter 29.
What are common classification mistakes for HS 293711?
A common error is misclassifying steroid hormones or amino-acid derivative hormones into HS 293711 due to a general understanding of "hormone." Importers must carefully distinguish between polypeptide/protein/glycoprotein structures and steroid or amino-acid structures. Another frequent mistake involves classifying prepared diagnostic reagents containing these hormones under 293711, when their primary function as a diagnostic kit dictates classification in 3822.00. 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 to avoid these errors, ensuring the specific chemical structure is prioritized.
How should importers classify products under HS 293711?
The correct procedure for classifying products under HS 293711 involves a multi-step approach. First, confirm the product's chemical identity as a polypeptide, protein, or glycoprotein hormone, or a derivative/structural analogue thereof, using laboratory analysis or manufacturer's specifications. Second, verify that it is not a steroid hormone (HS 2937.2X) or an amino-acid derivative hormone (HS 2937.90). Third, ensure the product is not a prepared diagnostic reagent (HS 3822.00). Importers and customs brokers should consult the WCO Explanatory Notes for Heading 2937, along with the specific national tariff schedules (e.g., HTSUS, EU TARIC), and consider requesting a binding ruling from the relevant customs authority for complex cases to ensure accurate and compliant classification.

FAQ
What are the Most Favored Nation (MFN) duty rates for products classified under HS 2937.11?
The MFN (Most Favored Nation) duty rates for goods classified under HS 2937.11, which covers 'Polypeptide hormones, protein hormones and glycoprotein hormones, their derivatives and structural analogues,' can vary significantly by importing country. For example, the United States generally applies a 'Free' (0.00% ad valorem) MFN duty rate for this subheading, as per the Harmonized Tariff Schedule of the United States (HTSUS). 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, such as 10% ad valorem in certain jurisdictions. Importers should always consult the specific tariff schedule of the destination country for the most accurate and up-to-date MFN duty rate.
What are the key classification criteria for products under HS 2937.11, and what distinguishes them from other hormone classifications?
HS 2937.11 specifically covers polypeptide hormones, protein hormones, and glycoprotein hormones, along with their derivatives and structural analogues. The primary classification criterion is the chemical structure: these are hormones characterized by their polypeptide or protein nature. This distinguishes them from steroid hormones (e.g., HS 2937.2x) or other types of hormones. Key considerations for classification include the molecular weight, amino acid sequence, and biological function as a hormone. Importers must provide detailed chemical and biological descriptions, including the specific name of the hormone (e.g., insulin, growth hormone), its origin (synthetic or natural), and its primary function, to ensure correct classification. The World Customs Organization's Explanatory Notes for Chapter 29 provide further guidance on distinguishing between different hormone types.
Are there any preferential duty rates available for HS 2937.11 under common trade agreements, and how can importers claim them?
Yes, preferential duty rates, often 'Free' (0.00% ad valorem), are frequently available for HS 2937.11 under various free trade agreements (FTAs) and generalized system of preferences (GSP) schemes. For instance, goods originating from countries party to agreements like the USMCA (United States-Mexico-Canada Agreement), EU-Japan EPA, or various GSP programs may qualify for reduced or zero duties. To claim preferential rates, importers must ensure the goods meet the specific Rules of Origin (ROO) criteria of the applicable agreement. This typically involves providing a valid Certificate of Origin or an origin declaration from the exporter, demonstrating that the product was wholly obtained or underwent sufficient transformation in the beneficiary country. Importers should consult the specific trade agreement's text and the importing country's customs regulations for detailed origin requirements and documentation.
What specific documentation is required for the import of polypeptide and protein hormones under HS 2937.11, beyond standard customs paperwork?
Beyond standard import documentation such as the commercial invoice, packing list, and bill of lading/air waybill, the import of products under HS 2937.11 often requires additional regulatory documentation due to their nature as pharmaceutical ingredients or finished pharmaceutical products. This may include: 1. Certificates of Analysis (CoA): Detailing the purity, potency, and composition of the hormone. 2. Material Safety Data Sheets (MSDS/SDS): Providing information on safe handling, storage, and emergency procedures. 3. FDA (or equivalent national health authority) approvals/licenses: If the product is intended for human or animal therapeutic use, it may require pre-market authorization or registration. 4. Import permits: Certain controlled substances or biological products may require specific import permits from health or agricultural authorities. 5. Pharmacopoeia compliance certificates: Demonstrating adherence to standards like USP, EP, or BP. Importers should verify specific requirements with the relevant regulatory agencies in the destination country prior to shipment.
