HS 292423 2-Acetamidobenzoic acid (N-acetylanthranilic acid) and its salts
Quick Answer: HS code 292423 specifically covers 2-Acetamidobenzoic acid, also known as N-acetylanthranilic acid, and its various salts. This chemical compound is primarily used as an intermediate in the synthesis of pharmaceuticals, dyes, and other organic chemicals. For importers and exporters, understanding the duty rates is crucial. In the UK, the standard Most Favoured Nation (MFN) duty rate is 6.00% ad valorem. The EU applies an MFN rate of 6.50% ad valorem. The US tariff schedule for this code is more complex, with MFN rates ranging from 15.4¢/kg + 58% to 6.5% ad valorem, depending on the specific product description and origin. Notably, the US also offers duty-free treatment under various preferential trade agreements (e.g., A+, AU, BH, CL, CO, D, E, IL, JO, KR, MA, OM, P, PA, PE, S, SG), which can significantly reduce import costs for eligible goods. Importers should verify the exact subheading and origin to leverage potential duty savings.

How to Classify This HS Code?
What products does HS 292423 cover?
This subheading covers 2-Acetamidobenzoic acid, also known as N-acetylanthranilic acid, and its various salts. This specific chemical compound is an amide-function compound, falling under Heading 2924 of the Harmonized System, which encompasses carboxyamide-function compounds; amide-function compounds of carbonic acid. The WCO Harmonized System Nomenclature explicitly identifies "2-Acetamidobenzoic acid (N-acetylanthranilic acid) and its salts" under subheading 2924.23. The USITC Harmonized Tariff Schedule (HTS) and the EU TARIC system both align with this specific classification, ensuring consistent global application for this distinct chemical entity.
What falls outside HS 292423?
The following products are excluded from HS 292423: Anthranilic acid (2-aminobenzoic acid) itself, which lacks the acetyl group, is classified under HS 2922.49 as an amino-acid. Derivatives of 2-acetamidobenzoic acid that have undergone further chemical modification beyond simple salt formation, such as esters or other complex derivatives, would generally fall into other subheadings within Chapter 29, depending on their specific chemical structure and functional groups. For instance, an ester of 2-acetamidobenzoic acid would likely be classified under a subheading for ester-function compounds, not under 2924.23, as it no longer precisely matches the defined chemical entity.
What are common classification mistakes for HS 292423?
A common error is misclassifying anthranilic acid (2-aminobenzoic acid) or its salts under HS 292423. While chemically related, anthranilic acid lacks the N-acetyl group that defines 2-acetamidobenzoic acid, and is correctly classified under HS 2922.49. Another mistake involves classifying complex derivatives or mixtures containing 2-acetamidobenzoic acid where the derivative or mixture imparts the essential character, rather than the pure compound. Proper application of 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 such errors, ensuring the product precisely matches the subheading's description.
How should importers classify products under HS 292423?
The correct procedure for classifying products under HS 292423 involves a meticulous review of the chemical's identity. Importers and customs brokers must verify that the product is precisely 2-acetamidobenzoic acid (N-acetylanthranilic acid) or one of its direct salts, as confirmed by chemical analysis or manufacturer's specifications. It is essential to consult the WCO Harmonized System Nomenclature, the USITC HTS, or the EU TARIC for the exact wording of subheading 2924.23. Any deviation in chemical structure, such as the absence of the acetyl group or the presence of additional functional groups beyond simple salt formation, would necessitate classification elsewhere within Chapter 29, following the General Interpretative Rules, particularly GRI 1.

FAQ
What is the Most Favored Nation (MFN) import duty rate for HS code 2924.23 in key markets?
The Most Favored Nation (MFN) import duty rates for '2-Acetamidobenzoic acid (N-acetylanthranilic acid) and its salts' (HS 2924.23) vary by country. For example, the general MFN duty rate in the United States is 6.5% ad valorem. In the European Union (EU TARIC), the MFN duty rate is typically 6.5% ad valorem. The United Kingdom Global Tariff (UKGT) also applies an MFN rate of 6.5% ad valorem. Other countries may have different MFN rates, such as 6.00% or a compound rate like 15.4¢/kg + 58% in specific jurisdictions. Importers should always consult the official tariff schedule of the importing country, such as the USITC Harmonized Tariff Schedule (HTS), EU TARIC, or UK Trade Tariff, for the most current and accurate MFN duty rate applicable at the time of import.
Are there any preferential duty rates available for HS 2924.23 under common trade agreements?
Yes, preferential duty rates, including 'Free' (0% ad valorem), are available for HS 2924.23 under various Free Trade Agreements (FTAs) and special programs, provided the goods meet the respective Rules of Origin. For instance, in the United States, preferential duty treatment is often available for imports from countries designated with special program indicators such as A+ (Generalized System of Preferences for Least Developed Beneficiary Developing Countries), AU (Australia FTA), BH (Bahrain FTA), CL (Chile FTA), CO (Colombia TPA), D (African Growth and Opportunity Act), E (Andean Trade Preference Act), IL (Israel FTA), JO (Jordan FTA), KR (Korea FTA), MA (Morocco FTA), OM (Oman FTA), P (Panama TPA), PA (Panama TPA), PE (Peru TPA), S (Singapore FTA), and SG (Singapore FTA). Importers must ensure they have the necessary documentation, such as a Certificate of Origin, to claim these preferential rates. Consult the specific trade agreement's text and the importing country's tariff schedule for detailed origin requirements.
What are the key classification criteria for '2-Acetamidobenzoic acid (N-acetylanthranilic acid) and its salts' under HS 2924.23?
HS code 2924.23 specifically covers '2-Acetamidobenzoic acid (N-acetylanthranilic acid) and its salts'. The primary classification criterion is the chemical identity of the substance. This heading falls under Chapter 29 of the Harmonized System, which covers 'Organic chemicals'. Specifically, Subheading 2924 covers 'Carboxyamide-function compounds; amide-function compounds of carbonic acid'. The .23 subdivision precisely identifies 2-Acetamidobenzoic acid and its salts. Importers must ensure that the chemical name, CAS number (if applicable), and chemical structure of the imported product precisely match the description for this heading. Any derivatives, isomers, or mixtures that do not predominantly consist of 2-Acetamidobenzoic acid or its salts may fall under different subheadings, such as other amide-function compounds or mixtures of organic chemicals, depending on their composition and principal characteristics. Laboratory analysis and Certificates of Analysis are crucial for accurate classification.
What documentation is typically required for importing goods classified under HS 2924.23?
For imports under HS 2924.23, standard customs documentation is required, including a commercial invoice, packing list, bill of lading or air waybill, and a customs declaration form. Additionally, due to the chemical nature of the product, specific chemical-related documentation is often necessary. This may include a Certificate of Analysis (CoA) from the manufacturer, a Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS), and potentially a technical data sheet confirming the chemical composition and purity. If claiming preferential duty rates under a Free Trade Agreement, a valid Certificate of Origin (e.g., NAFTA/USMCA Certificate, EUR.1 movement certificate, or a self-certification by the exporter) is mandatory. Importers should also be aware of any national chemical control regulations, such as those from the Environmental Protection Agency (EPA) in the U.S. or REACH regulations in the EU, which might require additional declarations or registrations.
