HS 292249 Other

The MFN duty rates for HS 2922.49 ('Amino-acids, other than those containing more than one type of oxygen function, their esters and salts thereof; and their derivatives') vary significantly by importing country. For instance, the United States (USITC) applies a general MFN duty rate of 6.5% ad valorem. The European Union (EU TARIC) and the United Kingdom (UK Trade Tariff) typically apply a 0.00% ad valorem MFN duty rate for most products under this subheading. Canada also generally applies a Free MFN duty rate. Importers should always verify the specific duty rate applicable to their destination country using the official tariff database, as rates can be product-specific within the subheading or subject to temporary suspensions or quotas.

HS 2922.49 is a residual 'Other' subheading for amino-acids, their esters, salts, and derivatives that do not fit into the more specific subheadings of 2922. It covers amino-acids that contain only one type of oxygen function (e.g., carboxylic acid, alcohol, phenol, ether, aldehyde, ketone) and are not specifically provided for elsewhere. Key classification criteria involve: 1. Chemical Structure: Identifying the presence and type of oxygen-containing functional groups. 2. Number of Oxygen Functions: Ensuring the molecule contains only one type of oxygen function. 3. Specificity: Confirming the substance is not explicitly named in subheadings 2922.11 through 2922.44 (e.g., Lysine, Glutamic acid, Glycine). If an amino-acid has multiple types of oxygen functions (e.g., both a carboxylic acid and a hydroxyl group not part of the amino acid structure itself), it would typically fall under 2922.50. Importers should refer to the Harmonized System Explanatory Notes for Chapter 29 for detailed guidance on functional group definitions and classification principles.

Many FTAs offer preferential duty treatment for products under HS 2922.49, often resulting in a 0.00% ad valorem rate. For example, products originating from Mexico or Canada imported into the U.S. may qualify for duty-free entry under the USMCA (United States-Mexico-Canada Agreement). Similarly, goods originating from various developing countries may be eligible for duty-free or reduced duties under Generalized System of Preferences (GSP) schemes in the U.S., EU, and UK. To claim preferential rates, importers must typically: 1. Meet Rules of Origin: The goods must satisfy the specific origin requirements of the FTA (e.g., wholly obtained, change in tariff classification, regional value content). 2. Provide Proof of Origin: A valid certificate of origin or declaration of origin from the exporter is usually required. 3. Make a Valid Claim: The importer or customs broker must correctly declare the preferential treatment at the time of import. Failure to meet these requirements can result in the application of the higher MFN duty rate.

Beyond standard import documentation such as the commercial invoice, packing list, and bill of lading/air waybill, chemical products under HS 2922.49 may require additional documentation depending on their specific nature and intended use. Key additional documents often include: 1. Safety Data Sheet (SDS): Essential for all chemical imports, providing information on hazards, safe handling, and emergency procedures. 2. Certificate of Analysis (CoA): Verifies the chemical composition, purity, and quality specifications, crucial for pharmaceutical or food-grade amino acids. 3. End-Use Certificates: In some jurisdictions, if the product is subject to specific regulations or duty exemptions based on its end-use (e.g., for pharmaceutical manufacturing), an end-use certificate may be required. 4. Import Licenses/Permits: While less common for general amino acids, certain derivatives or high-purity grades might require specific permits from health, environmental, or agricultural authorities, especially if they are precursors or controlled substances. Importers should consult the regulations of the specific importing country and the product's intended application.
