HS 300331 Other, containing hormones or other products of heading 2937
Quick Answer: Medicaments containing hormones or other products of heading 2937 imported under HS 300331 enter the UK at 0.00%, the EU at 0.00%, and the US at a Free rate under the MFN tariff. This classification specifically covers pharmaceutical preparations that contain hormones, such as insulin or corticosteroids, or other substances derived from living organisms that are classified under HS heading 2937. These are distinct from the raw hormones themselves. Importers and customs brokers should note that while MFN rates are often duty-free in major markets, specific trade agreements or end-use declarations might influence final duty liability.

How to Classify This HS Code?
What products does HS 300331 cover?
This subheading covers pharmaceutical preparations containing hormones or other products of heading 2937, which are not specified elsewhere in heading 3003. Heading 2937 encompasses steroid hormones, peptide hormones, and their derivatives. According to the World Customs Organization (WCO) Harmonized System Nomenclature, these preparations are typically presented in dosage forms or in packings for retail sale for medicinal or veterinary use, and are distinguished from finished pharmaceutical products of heading 3004 by their specific composition and intended application as active pharmaceutical ingredients or intermediates. The USITC Harmonized Tariff Schedule (HTS) and the EU TARIC database provide detailed interpretations of products falling under this category.
What falls outside HS 300331?
The following products are excluded from HS 300331: finished pharmaceutical products in dosage form or packings for retail sale for medicinal or veterinary use that are not specifically containing hormones or other products of heading 2937, which would be classified under other subheadings of 3003 or heading 3004. Also excluded are raw materials or bulk active pharmaceutical ingredients not yet formulated into preparations, which may fall under heading 2937. For instance, pure testosterone, a hormone, would be classified under 2937.21, not 300331, unless it is part of a pharmaceutical preparation.
What are common classification mistakes for HS 300331?
A common error is misclassifying bulk active pharmaceutical ingredients (APIs) that are hormones or derived from heading 2937. According to General Rule of Interpretation (GRI) 1, classification is determined by the terms of the headings and any relative section or chapter notes. If a product is a pure hormone or a specific derivative listed in heading 2937, it should be classified there, not under 300331, which requires the product to be a "preparation." Importers may also incorrectly classify finished dosage forms intended for direct patient use under 300331 instead of 3004.
How should importers classify products under HS 300331?
The correct procedure for classifying products under HS 300331 involves a thorough review of the product's composition and presentation. Importers and customs brokers must first determine if the product contains hormones or other substances classified under heading 2937. Next, they must ascertain if the product is a "preparation" as understood by Chapter 30, meaning it is formulated for medicinal or veterinary use, often in a specific dosage form or retail packaging. Consulting the WCO Explanatory Notes, USITC HTS, and EU TARIC is crucial to confirm the scope and ensure accurate classification.
How is the duty calculated for products under HS 300331?
A shipment of 10,000 units of synthetic insulin (a peptide hormone preparation) declared at a customs value of $5,000 USD would attract a US duty of $250.00. This is calculated using the Most Favored Nation (MFN) rate of 5.0% ad valorem published in the USITC Harmonized Tariff Schedule (HTS) for subheading 3003.31.90. The duty is calculated as 5.0% of the declared customs value: 0.05 × $5,000 USD = $250.00. Note that specific quantities might also be subject to specific duties in some jurisdictions.
Which trade agreements reduce duties for HS 300331?
Several free trade agreements may reduce the applicable duty rate for HS 300331, including the United States-Mexico-Canada Agreement (USMCA) and the European Union-United Kingdom Trade and Cooperation Agreement. Under USMCA, products originating in Canada or Mexico may be eligible for Free (0%) duty. For EU/UK preferences, originating products can also receive Free (0%) duty. Documentation required includes a self-certified origin statement for USMCA and an EUR.1 movement certificate or origin declaration for EU/UK preferences, depending on the value and specific rules.

FAQ
What are the typical import duty rates for HS code 300331?
Import duty rates for HS code 300331, 'Other, containing hormones or other products of heading 2937', vary significantly by country. For example, under the US Harmonized Tariff Schedule (HTS), the Most Favored Nation (MFN) rate is often 0.00%. However, preferential rates under trade agreements can also apply. The EU's TARIC system and the UK's Trade Tariff will show specific rates for imports into those regions, which may differ. Always consult the specific tariff schedule of the importing country for the most accurate and up-to-date duty information.
How is the classification of goods under HS 300331 determined?
Classification under HS code 300331 requires that the product is 'other' medicaments (not specified elsewhere in heading 3003 or 3004) and that it contains hormones or other products of heading 2937. Heading 2937 covers organic chemicals that are hormones, their derivatives, and other steroids used primarily as hormones. The World Customs Organization (WCO) Harmonized System Explanatory Notes provide detailed guidance. Importers must verify that the active ingredients are indeed hormones or related compounds classified under 2937 and that the product is presented in a form suitable for therapeutic or prophylactic uses.
What documentation is typically required for importing goods classified under HS 300331?
When importing goods under HS code 300331, standard import documentation is required, including a commercial invoice, packing list, and bill of lading/air waybill. Additionally, specific to medicaments containing hormones, importers may need to provide a Certificate of Analysis (CoA) from the manufacturer, a product registration or marketing authorization from the importing country's health authority (e.g., FDA in the US, EMA in the EU), and potentially a free sale certificate. Customs authorities may also request safety data sheets (SDS) or other technical documentation to verify the composition and intended use of the product.
How are duties calculated for HS 300331, and can you provide an example?
The duty calculation for HS 300331 depends on the specific duty rate applied by the importing country. If the rate is 'ad valorem' (based on value), the duty is a percentage of the customs value. If it's a 'specific duty' (based on quantity), it's a fixed amount per unit. For example, if a country applies a 5% ad valorem duty rate to HS 300331, and the customs value of a shipment is $10,000, the duty would be calculated as: $10,000 (Customs Value) × 0.05 (Duty Rate) = $500 (Duty Amount). If a specific duty applied, such as $2 per kilogram, and the shipment weighed 100 kg, the duty would be 100 kg × $2/kg = $200.
Do trade agreements, such as USMCA or EU trade deals, affect the duty rates for HS 300331?
Yes, trade agreements can significantly impact duty rates for HS code 300331. For instance, if a product originates from a country that has a free trade agreement with the importing country (e.g., USMCA for imports into the US from Canada or Mexico, or various EU trade agreements), it may qualify for preferential duty rates, often resulting in a 0.00% duty. To claim preferential treatment, importers must typically provide proof of origin, such as a certificate of origin, demonstrating that the goods meet the rules of origin stipulated in the respective trade agreement. Always verify the origin of your goods and consult the specific trade agreement for eligibility and documentation requirements.
