HS 292243 Anthranilic acid and its salts

What products does HS 292243 cover?

This subheading covers anthranilic acid and its salts, which are amino-acids containing other oxygen function. Anthranilic acid, chemically known as 2-aminobenzoic acid, is an aromatic amino acid with the chemical formula C7H7NO2. It is characterized by both an amino group (-NH2) and a carboxyl group (-COOH) attached to a benzene ring. The scope explicitly includes the free acid form and any of its chemically defined salts, such as sodium anthranilate or methyl anthranilate, provided they are not otherwise specified elsewhere in the Nomenclature. This classification is consistent with the World Customs Organization (WCO) Harmonized System Explanatory Notes for Chapter 29 and is reflected in the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC system.

What falls outside HS 292243?

The following products are excluded from HS 292243: esters of anthranilic acid (other than salts), such as methyl anthranilate, which are typically classified under HS 2922.49 as "other amino-acids containing other oxygen function." Derivatives of anthranilic acid where the amino group or carboxyl group has been further modified, beyond simple salt formation, would also be excluded and classified according to their specific chemical structure and functional groups. For instance, N-acetylanthranilic acid, where the amino group is acetylated, would fall under a different subheading, likely within 2924, as an amide-function compound. Similarly, mixtures or preparations containing anthranilic acid but not being chemically defined pure substances are generally excluded from Chapter 29 and classified elsewhere based on their composition and intended use.

What are common classification mistakes for HS 292243?

A common error is misclassifying esters of anthranilic acid, such as methyl anthranilate, directly under 292243. While methyl anthranilate is derived from anthranilic acid, it is an ester, not a salt, and therefore falls under HS 2922.49. Importers often overlook the distinction between "salts" and "esters," leading to incorrect declarations. Another mistake involves classifying crude or impure forms of anthranilic acid or its salts under this subheading when they do not meet the purity requirements for chemically defined organic compounds of Chapter 29. General Interpretative Rule (GRI) 1 dictates that classification is determined according to the terms of the headings and any relative section or chapter notes, emphasizing the need for precise chemical identification. Failure to correctly identify the specific chemical form (acid, salt, or ester) is a frequent source of error.

How should importers classify products under HS 292243?

The correct procedure for classifying products under HS 292243 involves first verifying the chemical identity of the substance. Importers and customs brokers must confirm through chemical analysis, safety data sheets (SDS), or certificates of analysis that the product is indeed anthranilic acid or a chemically defined salt thereof. It is crucial to distinguish salts from esters or other derivatives. If the substance is an ester, it will likely fall under HS 2922.49. Furthermore, ensure the product meets the purity standards for "chemically defined organic compounds" as generally understood within Chapter 29. Always consult the WCO Harmonized System Explanatory Notes, the USITC HTS, or the EU TARIC for the most current and detailed guidance, paying close attention to any specific chapter or subheading notes that might impact classification. Accurate documentation confirming the chemical structure and purity is essential for compliance.
