How to Classify This HS Code?
What products does HS 292630 cover?
This subheading covers two specific chemical compounds: Fenproporex (INN) and its salts, and methadone (INN) intermediate (4-cyano-2-dimethylamino-4,4-diphenylbutane). Fenproporex is an anorectic drug, while the latter is a crucial precursor in the synthesis of methadone, a synthetic opioid. The World Customs Organization (WCO) Harmonized System Nomenclature explicitly defines these substances under this code, and this definition is consistently adopted by major customs authorities such as the United States International Trade Commission (USITC) Harmonized Tariff Schedule (HTS) and the European Union's TARIC database, ensuring global uniformity in their classification as specific organic chemicals within Chapter 29.
What falls outside HS 292630?
The following products are excluded from HS 292630: finished pharmaceutical formulations containing fenproporex or methadone intermediate, which would typically be classified in Chapter 30 as medicaments. For example, a tablet containing fenproporex as an active ingredient, prepared for therapeutic use, would fall under heading 3004. Similarly, pure methadone (INN) itself, being a finished drug substance, is classified under HS 2925. Other nitriles not specifically named in this subheading, even if structurally similar, would be classified under other appropriate subheadings within Heading 2926, such as 2926.90 for other nitriles.
What are common classification mistakes for HS 292630?
A common error is misclassifying finished pharmaceutical products containing fenproporex or methadone intermediate within this subheading, rather than under Chapter 30. Importers sometimes overlook the distinction between bulk chemical substances and prepared medicaments, leading to incorrect tariff application. Another mistake involves classifying other nitriles or related organic chemicals that are not specifically Fenproporex (INN) and its salts, or 4-cyano-2-dimethylamino-4,4-diphenylbutane, under this specific code. Adherence to General Interpretative Rule (GRI) 1, which dictates classification by the terms of the headings and any relative section or chapter notes, is crucial to avoid these errors, ensuring the precise chemical identity matches the subheading's explicit description.
How should importers classify products under HS 292630?
The correct procedure for classifying products under HS 292630 involves a meticulous review of the chemical identity and form of the imported substance. Importers and customs brokers must first confirm that the product is either Fenproporex (INN) or its salts, or 4-cyano-2-dimethylamino-4,4-diphenylbutane, and that it is in a bulk chemical form, not a prepared medicament. Obtain a Certificate of Analysis (CoA) or Safety Data Sheet (SDS) to verify the exact chemical name, CAS number, and purity. Cross-reference these details with the WCO HS Explanatory Notes for Heading 2926 and the specific definitions provided in the USITC HTS or EU TARIC for subheading 292630. If any doubt exists, consider requesting a binding ruling from the relevant customs authority to ensure compliance and avoid potential penalties.

HS 2926.30 specifically covers 'Fenproporex (INN) and its salts; methadone (INN) intermediate (4-cyano-2-dimethylamino-4,4-diphenylbutane)'. The primary classification criterion is the chemical identity of the substance. 'INN' stands for International Nonproprietary Name, which provides a unique and globally recognized name for pharmaceutical substances. Importers and customs brokers must ensure that the chemical name, CAS number, and molecular structure precisely match the descriptions for Fenproporex or the specified methadone intermediate. Misclassification can occur if similar but chemically distinct nitriles (Chapter 29, Subheading 2926) are incorrectly assigned. Laboratory analysis or a detailed Certificate of Analysis (CoA) from the manufacturer confirming the exact chemical composition is often essential for accurate classification.
What specific documentation is required for importing substances classified under HS 2926.30, given their nature?
Due to the pharmaceutical and controlled substance-related nature of Fenproporex and Methadone intermediates, importing substances under HS 2926.30 typically requires stringent documentation beyond standard customs declarations. This often includes: 1. Commercial Invoice and Packing List: Standard shipping documents. 2. Certificate of Analysis (CoA): Detailing chemical purity, composition, and manufacturing batch. 3. Safety Data Sheet (SDS): Providing information on hazards, handling, and emergency procedures. 4. Import Licenses/Permits: Issued by national drug regulatory authorities (e.g., DEA in the US, EMA in the EU, MHRA in the UK) due to these substances potentially being controlled or precursor chemicals. 5. End-Use Certificates: May be required to confirm the legitimate industrial or pharmaceutical application. 6. Certificate of Origin: To claim preferential duty rates under trade agreements. Importers should consult the specific regulations of the importing country's health and drug control agencies in addition to customs authorities.
