HS 293961 Alkaloids of rye ergot and their derivatives; salts thereof

Quick Answer: HS Code 2939.61 covers alkaloids derived from ergot (a fungus that grows on rye and similar grains) and their chemical derivatives, including their various salt forms. These substances are primarily used in pharmaceuticals due to their potent biological activity, for example, in treating migraines or controlling bleeding. For importers and exporters, understanding the duty rates is crucial. The United Kingdom and the European Union generally apply a 0.00% ad valorem duty rate to products classified under 2939.61, indicating duty-free entry. In contrast, the United States applies a "Free" duty rate for most favored nation (MFN) treatment, but a 25% ad valorem rate may apply under specific trade provisions, such as Section 301 duties, depending on the country of origin. Always verify the specific origin and applicable trade programs to determine the precise duty liability.

How to Classify This HS Code?

What products does HS 293961 cover?

This subheading covers alkaloids derived from rye ergot (Claviceps purpurea) and their various chemical derivatives, as well as the salts of these compounds. According to the Harmonized System Explanatory Notes (HSEN) for Heading 2939, this specifically includes the complex nitrogenous organic bases found in ergot, such as ergotamine, ergometrine (ergonovine), and ergotoxine. These substances are characterized by their specific chemical structures and pharmacological properties, often used in pharmaceuticals. The scope is precisely defined by the WCO's nomenclature and reflected in national tariffs like the USITC Harmonized Tariff Schedule of the United States (HTSUS) and the EU TARIC system, ensuring consistent global classification for these specialized organic chemicals.

What falls outside HS 293961?

The following products are excluded from HS 293961: synthetic analogues that do not originate from ergot alkaloids, even if they possess similar pharmacological effects, as these would typically fall under other subheadings within Chapter 29 for synthetic organic compounds. Additionally, pharmaceutical preparations (medicaments) containing ergot alkaloids, put up in measured doses or in forms or packings for retail sale, are excluded and classified under Heading 3004. For instance, an injectable solution of ergometrine maleate for medical use would be classified under 3004, not 293961, because it is a finished medicament, not merely the raw alkaloid or its salt.

What are common classification mistakes for HS 293961?

A common error is misclassifying pharmaceutical preparations containing ergot alkaloids under HS 293961 instead of Heading 3004. This mistake often arises from failing to apply General Interpretative Rule (GRI) 3(a), which prioritizes the more specific heading. Heading 3004 specifically covers "Medicaments... put up in measured doses or in forms or packings for retail sale," which is more specific than Heading 2939 for isolated organic compounds. Another frequent mistake involves classifying synthetic compounds with similar structures or uses but not derived from ergot under this subheading, overlooking the explicit "of rye ergot" requirement, which is a crucial chemical origin criterion for this specific classification.

How should importers classify products under HS 293961?

The correct procedure for classifying products under HS 293961 involves a meticulous review of the product's chemical identity, origin, and form. Importers and customs brokers must first confirm that the product is indeed an alkaloid derived from rye ergot or a direct chemical derivative or salt thereof, as specified by the WCO HSEN for Heading 2939. Crucially, verify that the product is not a finished pharmaceutical preparation (medicament) put up for retail sale or in measured doses, which would necessitate classification under Heading 3004. Always consult the latest national tariff schedules, such as the USITC HTSUS or EU TARIC, and cross-reference with chemical analysis reports and manufacturing specifications to ensure accurate and compliant classification.

FAQ

What are the typical Most Favored Nation (MFN) duty rates for products classified under HS 2939.61 ('Alkaloids of rye ergot and their derivatives; salts thereof')?

For products classified under HS 2939.61, the MFN duty rates can vary significantly by importing country. For example, the United States generally applies a 'Free' (0.00%) duty rate for goods from MFN countries under the Harmonized Tariff Schedule of the United States (HTSUS). The European Union's TARIC database also typically indicates a 0.00% ad valorem duty rate for MFN imports. However, other countries may apply different rates, such as 25% ad valorem, depending on their national tariff schedules. Importers should always verify the specific duty rate applicable to their destination country using official tariff databases like the USITC HTSUS, EU TARIC, or the UK Trade Tariff.

Are there any preferential duty rates available for alkaloids of rye ergot (HS 2939.61) under common trade agreements?

Yes, preferential duty rates are often available for HS 2939.61 under various free trade agreements (FTAs) and generalized system of preferences (GSP) programs. For instance, under agreements like the USMCA (United States-Mexico-Canada Agreement) or numerous EU FTAs, goods originating from partner countries are typically eligible for a 0.00% duty rate, provided they meet the specific rules of origin requirements. Similarly, many developing countries may benefit from GSP schemes, which often grant duty-free access for these products. Importers must ensure they have the correct origin documentation, such as a certificate of origin, to claim preferential treatment.

What are the key classification criteria for determining if a product falls under HS 2939.61?

The classification under HS 2939.61 is specifically for 'Alkaloids of rye ergot and their derivatives; salts thereof'. This heading covers naturally occurring alkaloids derived from the ergot fungus (Claviceps purpurea) that grows on rye, as well as their chemically modified derivatives and the salts of both the natural alkaloids and their derivatives. Key criteria include the chemical structure confirming its origin or derivation from rye ergot alkaloids (e.g., ergotamine, ergometrine, bromocriptine) and its presentation as a pure compound or salt. Mixtures or preparations containing these substances, but not consisting solely of them, might be classified elsewhere, typically in Chapter 30 if they are medicaments. Reference to the WCO Explanatory Notes for Chapter 29, specifically heading 29.39, provides further guidance.

What specific documentation is typically required for importing products classified under HS 2939.61?

Beyond standard customs documentation such as a commercial invoice, packing list, and bill of lading/air waybill, importers of HS 2939.61 products may require additional specific documents due to their pharmaceutical or chemical nature. These can include:

  1. Certificate of Analysis (CoA): To verify the chemical composition, purity, and concentration.
  2. Safety Data Sheet (SDS): For hazard communication and safe handling.
  3. Manufacturer's Declaration: Confirming the product's identity and origin.
  4. Import Licenses/Permits: Depending on the destination country's regulations for controlled substances or pharmaceutical ingredients. Many ergot alkaloids are precursors for illicit substances and are subject to strict controls under international conventions (e.g., UN Convention against Illicit Traffic in Narcotic Drugs and Psychotropic Substances of 1988), requiring specific permits from national drug control agencies. Importers should consult the relevant national regulatory bodies (e.g., FDA in the US, EMA in the EU) for specific requirements.
