HS 292244 Tilidine (INN) and its salts
Quick Answer: HS Code 2922.44 specifically covers Tilidine (INN) and its salts. Tilidine is a synthetic opioid analgesic primarily used for pain relief. This classification falls under Chapter 29, which deals with organic chemicals, and more specifically, under subheading 2922 for oxygen-function amino-compounds. For importers and exporters, understanding this precise classification is crucial for compliance. The United Kingdom and the European Union generally apply a 0.00% ad valorem duty rate to products under this code. In contrast, the United States imposes a more complex duty structure, typically "Free" for most favored nation (MFN) status, but also lists a column 2 rate of 15.4¢/kg + 45% ad valorem. Given Tilidine's nature as a controlled substance in many jurisdictions, trade in these products is subject to stringent regulatory controls, licensing requirements, and potential import/export restrictions beyond standard customs duties.

How to Classify This HS Code?
What products does HS 292244 cover?
This subheading covers Tilidine (INN) and its salts, which are specifically identified as amino-alcohols, amino-naphthols and other amino-phenols, their ethers and esters, other than those containing more than one type of oxygen function, falling under Heading 2922. Tilidine is an opioid analgesic, chemically known as (±)-ethyl 2-(dimethylamino)-1-phenylcyclohex-3-ene-1-carboxylate. The inclusion of "INN" (International Nonproprietary Name) signifies its recognition as a unique pharmaceutical substance. This classification is consistent across the Harmonized System Nomenclature as published by the World Customs Organization (WCO), and reflected in national tariffs such as the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC system, ensuring global uniformity for this specific chemical compound and its various salt forms.
What falls outside HS 292244?
The following products are excluded from HS 292244: other amino-alcohols, amino-naphthols, and amino-phenols that are not Tilidine or its salts. For instance, other opioid analgesics, even if structurally similar but not Tilidine, would be classified elsewhere, potentially under other subheadings within Chapter 29 if they are distinct chemical compounds, or even Chapter 30 if they are presented as medicaments. For example, tramadol, another synthetic opioid, would not fall under 292244. Furthermore, preparations containing Tilidine in measured doses or put up for retail sale as medicaments are classified under Heading 3004, as per the Explanatory Notes to Chapter 30, which prioritizes medicaments over pure chemical compounds when presented in specific forms for therapeutic or prophylactic uses.
What are common classification mistakes for HS 292244?
A common error is misclassifying Tilidine when it is incorporated into a pharmaceutical preparation. Importers sometimes incorrectly classify finished dosage forms of Tilidine under 292244, which is reserved for the pure chemical substance and its salts. According to General Interpretative Rule (GRI) 3(a) and the Explanatory Notes, medicaments (e.g., tablets, capsules, injections) containing Tilidine, even if it is the sole active ingredient, are classified under Heading 3004. Another mistake involves confusing Tilidine with other amino-alcohols or amino-phenols that might have similar chemical structures but are distinct compounds, leading to incorrect application of subheadings within Heading 2922. Careful attention to the specific chemical name and INN designation is crucial to avoid such errors.
How should importers classify products under HS 292244?
The correct procedure for classifying products under HS 292244 involves verifying that the imported substance is precisely Tilidine (INN) or one of its chemical salts, and not a preparation or medicament. Importers and customs brokers should obtain a Certificate of Analysis (CoA) or a Safety Data Sheet (SDS) for the product, which clearly identifies the chemical name, CAS number, and INN designation. If the product is a pure chemical substance matching "Tilidine (INN) and its salts," then 292244 is appropriate. If the product is in measured doses or packaged for retail sale as a medicament, it must be classified under Heading 3004. Consulting the WCO Harmonized System Explanatory Notes for Chapter 29 and Chapter 30, alongside national tariff schedules like the USITC HTS or EU TARIC, is essential for accurate and compliant classification.

FAQ
What are the typical Most Favored Nation (MFN) duty rates for Tilidine (INN) and its salts under HS code 2922.44?
The MFN duty rates for HS 2922.44, 'Tilidine (INN) and its salts,' can vary significantly by importing country. For example, the United States generally applies a 'Free' rate for MFN (Normal Trade Relations) countries. The European Union's TARIC database also typically indicates a 0.00% ad valorem duty rate for MFN imports. However, other jurisdictions might apply different rates, such as a specific duty or a combination. Importers should always consult the official customs tariff of the destination country, such as the USITC Tariff Database, EU TARIC, or the UK Trade Tariff, for the most current and precise MFN duty rate applicable to their specific import.
Are there any preferential duty rates available for Tilidine (INN) and its salts under HS 2922.44 through free trade agreements?
Yes, preferential duty rates are often available for HS 2922.44 depending on the country of origin and existing free trade agreements (FTAs) or preferential trade programs. For instance, imports into the United States from countries party to agreements like USMCA (NAFTA successor), CAFTA-DR, or GSP-eligible countries may qualify for a 0.00% duty rate, provided all rules of origin requirements are met. Similarly, the EU has numerous FTAs (e.g., with South Korea, Japan, Canada) that could grant preferential treatment. Importers must ensure they have the necessary documentation, such as a certificate of origin, to claim these preferential rates. Always verify specific agreement terms and origin rules through official customs resources like the USITC or EU TARIC.
What are the key classification criteria for Tilidine (INN) and its salts under HS 2922.44?
HS code 2922.44 specifically covers 'Tilidine (INN) and its salts.' The primary classification criterion is the chemical identity of the substance. Tilidine is an opioid analgesic, and its chemical structure and International Nonproprietary Name (INN) are definitive for its placement here. This heading is part of Chapter 29, which covers 'Organic chemicals,' and more specifically, within subheading 2922, 'Oxygen-function amino-compounds.' Importers must ensure that the product's chemical name, CAS number, and any relevant pharmacopoeial standards (e.g., USP, EP) align precisely with the description for Tilidine or its salts to ensure accurate classification. Misclassification could lead to incorrect duty assessments or regulatory non-compliance.
What specific documentation is required for importing Tilidine (INN) and its salts under HS 2922.44, given its nature as a controlled substance?
Beyond standard customs documentation (commercial invoice, packing list, bill of lading/airway bill), importing Tilidine (INN) and its salts under HS 2922.44 typically requires stringent regulatory permits due to its status as a controlled substance in many jurisdictions. In the United States, this would necessitate permits from the Drug Enforcement Administration (DEA) for both import and potentially for handling. Similar national drug regulatory authorities (e.g., European Medicines Agency (EMA) in the EU, Medicines and Healthcare products Regulatory Agency (MHRA) in the UK) will have specific licensing and import authorization requirements. Importers must obtain these permits prior to shipment. A detailed chemical analysis report or Certificate of Analysis (CoA) confirming the identity and purity of the substance is also highly recommended and often required by regulatory bodies. Failure to secure all necessary permits will result in significant delays, penalties, or seizure of the goods.
