HS 293890 Other
Quick Answer: HS code 293890, "Other," encompasses a diverse range of natural or reproduced glycosides and their derivatives, as well as vegetable alkaloids and their derivatives, not elsewhere specified in Heading 2938. This residual category captures various complex organic compounds primarily used in pharmaceuticals, research, and specialized chemical applications. Duty rates vary significantly by jurisdiction and specific product. In the UK, rates typically range from 4.00% to 6.00% ad valorem. The EU TARIC system shows rates from 0.00% to 6.50% ad valorem. For the US, the general Most Favored Nation (MFN) rate is 3.7% ad valorem, with many products eligible for duty-free entry under various Free Trade Agreements (e.g., A*, AU, BH, CL, CO, IL, KR, MA, PA, PE, SG). Importers should verify the specific 10-digit subheading and applicable trade agreements to determine the precise duty liability and ensure compliance.

How to Classify This HS Code?
What products does HS 293890 cover?
This subheading covers glycosides, natural or reproduced by synthesis, and their salts, ethers, esters, and other derivatives, which are not specifically provided for in subheading 2938.10. It acts as a residual category for the "other" glycosides and their derivatives within Heading 2938, which itself encompasses "Glycosides, natural or reproduced by synthesis, and their salts, ethers, esters and other derivatives." This includes a broad range of complex organic compounds characterized by a sugar molecule (glycone) linked to a non-sugar component (aglycone), as detailed in the World Customs Organization's Harmonized System Explanatory Notes for Heading 2938 and reflected in the USITC Harmonized Tariff Schedule (HTS) and EU TARIC. Examples might include certain saponins or flavone glycosides not specifically enumerated elsewhere.
What falls outside HS 293890?
The following products are excluded from HS 293890: rutoside (rutin) and its derivatives, which are specifically classified under subheading 2938.10. Furthermore, antibiotics, even if they contain a glycosidic structure, are generally classified in Heading 2941. Vitamins, provitamins, and their derivatives are classified in Heading 2936. Alkaloids, which are nitrogen-containing organic bases, are classified in Heading 2939, even if they possess a glycosidic linkage. Preparations containing glycosides, but formulated for therapeutic or prophylactic uses, are typically classified in Chapter 30, such as medicaments of Heading 3004, rather than as isolated chemical compounds in Chapter 29.
What are common classification mistakes for HS 293890?
A common error is misclassifying specific glycosides that have their own dedicated subheadings, particularly rutoside and its derivatives, which belong in 2938.10, into the residual 2938.90. Another frequent mistake involves classifying complex mixtures or pharmaceutical preparations containing glycosides into Chapter 29, when their primary function or composition dictates classification in Chapter 30 as medicaments or other preparations. Importers sometimes overlook the specific provisions of General Interpretative Rule (GRI) 3(b) when a product consists of more than one material or substance, leading to incorrect classification if the glycoside is not the essential character. Additionally, distinguishing between pure chemical compounds and formulated products can be challenging, often resulting in misapplication of Chapter 29 versus Chapter 30.
How should importers classify products under HS 293890?
The correct procedure for classifying products under HS 293890 involves a systematic review of the product's chemical structure and specific identity. Importers and customs brokers must first confirm that the product is indeed a glycoside or a derivative thereof, as defined by Heading 2938. Subsequently, it is crucial to check if the specific glycoside, such as rutoside, is enumerated in subheading 2938.10. If the product is not specifically named in 2938.10, and it meets the general description of Heading 2938, then classification under the residual subheading 2938.90 is appropriate. Always consult the latest version of the WCO HS Explanatory Notes, the USITC HTS, or the EU TARIC for definitive guidance and any binding rulings for similar products to ensure accuracy and compliance.

FAQ
What is the Most Favored Nation (MFN) import duty rate for HS 2938.90 'Other' in key markets, and how do preferential rates apply?
The MFN (Most Favored Nation) import duty rates for HS 2938.90 'Glycosides, natural or reproduced by synthesis, and their salts, ethers, esters and other derivatives: Other' vary significantly by importing country. For instance, the United States applies an MFN duty rate of 3.7% ad valorem (USITC Harmonized Tariff Schedule, Chapter 29, Subheading 2938.90.00). The European Union's TARIC database indicates an MFN duty rate of 6.50% ad valorem for this subheading. The UK Global Tariff also lists an MFN rate of 6.50% ad valorem. Preferential duty rates are available under various Free Trade Agreements (FTAs) or Generalized System of Preferences (GSP) schemes. For example, under the U.S. HTS, goods originating from countries with which the U.S. has FTAs (e.g., Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Jordan (JO), Korea (K), Morocco (MA), Oman (OM), Panama (PA), Peru (PE), Singapore (SG)) may be eligible for a 'Free' duty rate, provided all rules of origin requirements are met. Importers should consult the specific trade agreement and their country's tariff schedule for precise preferential rate eligibility and documentation requirements.
What are the primary classification criteria for products under HS 2938.90, especially given its 'Other' designation?
HS 2938.90 is the residual subheading for 'Glycosides, natural or reproduced by synthesis, and their salts, ethers, esters and other derivatives' that are not specifically enumerated in subheadings 2938.10 (Rutoside (rutin) and its derivatives) or 2938.90 (Other). Classification under 2938.90 requires the product to be a glycoside or a derivative thereof, as defined by the World Customs Organization (WCO) Explanatory Notes to Chapter 29. A glycoside is an organic compound in which a sugar molecule (glycone) is bonded to a non-sugar molecule (aglycone or genin) through a glycosidic bond. Importers must ensure the chemical structure and function align with the definition of a glycoside or its specified derivatives. Products that are not glycosides or their derivatives, even if complex organic chemicals, would be classified elsewhere in Chapter 29 or other chapters, depending on their specific chemical composition and function. Detailed chemical analysis and product specifications are crucial for accurate classification.
What specific documentation is required for importing goods classified under HS 2938.90, particularly to claim preferential duty rates?
For imports under HS 2938.90, standard customs documentation includes a commercial invoice, packing list, bill of lading or air waybill, and a customs declaration form. To claim preferential duty rates under a Free Trade Agreement (FTA) or GSP scheme (e.g., 'Free' rates for countries like Australia, Korea, or Singapore in the U.S. market), specific origin documentation is mandatory. This typically involves a Certificate of Origin (e.g., Form A for GSP, or a specific FTA certificate/declaration) issued by the exporting country's authorized body or a self-certification by the exporter, attesting that the goods meet the relevant rules of origin. Importers must retain these documents for the prescribed period (e.g., 5 years in the U.S.) for potential customs audits. Failure to provide valid origin documentation will result in the application of the higher MFN duty rate.
Are there any common trade agreements or special provisions that frequently impact the import of products under HS 2938.90?
Yes, numerous trade agreements significantly impact the import of products under HS 2938.90. For U.S. imports, agreements such as the USMCA (formerly NAFTA), CAFTA-DR, and FTAs with countries like Australia, Chile, Colombia, Israel, Jordan, Korea, Morocco, Oman, Panama, Peru, and Singapore often provide duty-free access for qualifying goods. In the EU, the extensive network of FTAs (e.g., with Japan, Canada, UK) and GSP schemes can offer reduced or zero duties. Similarly, the UK's independent trade agreements will influence rates. Given the 'Other' nature of this subheading, it encompasses a wide range of chemical compounds, some of which may be pharmaceutical intermediates or active pharmaceutical ingredients (APIs). Therefore, specific provisions related to pharmaceutical products in FTAs, which sometimes offer duty elimination, might be relevant. Importers should always verify the specific product's eligibility under the relevant trade agreement's rules of origin and product-specific rules.
