HS 292019 Other
Quick Answer: HS code 292019, "Other," encompasses a diverse range of esters of other inorganic acids (excluding halogenated derivatives) not specifically classified elsewhere within heading 2920. This includes various organic compounds containing an ester functional group derived from an inorganic acid, such as certain phosphates, phosphites, or borates, provided they are not covered by more specific subheadings like 292011 (dimethyl phosphite) or 292012 (trimethyl phosphite). Duty rates for products under 292019 vary significantly by jurisdiction and specific product. In the UK, rates can range from 0.00% to 6.00% ad valorem. The EU TARIC system shows rates from 0.00% to 6.50% ad valorem. For the US, rates are particularly complex, including 6.5% ad valorem, "Free" for goods originating from numerous Free Trade Agreement partners (e.g., A, AU, CL, KR), and a compound rate of 15.4¢/kg + 64.5% ad valorem for certain items. Importers and customs brokers must verify the exact 10-digit tariff line and country of origin to determine the applicable duty, especially given the potential for compound duties and FTA benefits in the US.

How to Classify This HS Code?
What products does HS 292019 cover?
This subheading covers other esters of inorganic acids (other than esters of hydrogen halides) and their salts, specifically those not elsewhere specified within HS 2920.11 (phosphite esters) or 2920.12 (trimethyl phosphite). This includes a broad range of chemical compounds, such as certain phosphate esters, sulfate esters, and nitrate esters, provided they are organic compounds of a known chemical structure and meet the criteria for classification within Chapter 29 as separate chemically defined organic compounds. The WCO Harmonized System Explanatory Notes for Heading 2920 clarify that this heading encompasses esters of inorganic acids, excluding those of hydrogen halides, and their salts and halogenated, sulfonated, nitrated, or nitrosated derivatives. Examples include triethyl phosphate, which is not specifically enumerated elsewhere.
What falls outside HS 292019?
The following products are excluded from HS 292019: esters of hydrogen halides, which are classified in Heading 2903. Furthermore, specific phosphite esters like trimethyl phosphite are classified in 2920.12, and other phosphite esters are classified in 2920.11, thus falling outside the "other" category. Polyphosphates, even if they are esters, might be classified elsewhere if they form part of a polymer or a preparation. Preparations containing these esters, where the ester is not the sole or principal component, are also excluded and would typically be classified in Chapter 38 or other relevant chapters based on their function and composition, as per General Interpretative Rule 3(b).
What are common classification mistakes for HS 292019?
A common error is misclassifying specific phosphite esters, such as triethyl phosphite, into 292019 instead of the more specific subheadings 292011 or 292012. Importers often overlook the specific enumeration for phosphite esters, leading to incorrect classification. Another frequent mistake involves classifying mixtures or preparations containing these esters under 292019, when in fact, such products should be classified under Chapter 38 or other functional chapters if the ester is not a separate chemically defined compound or if it is part of a formulated product. Applying General Interpretative Rule 1, which states that classification is determined according to the terms of the headings and any relative section or chapter notes, is crucial to avoid these errors.
How should importers classify products under HS 292019?
The correct procedure for classifying products under HS 292019 involves first confirming that the product is an ester of an inorganic acid (other than a hydrogen halide) and a separate chemically defined organic compound. Importers and customs brokers must meticulously review the chemical structure to ensure it is not a phosphite ester specifically covered by 2920.11 or 2920.12. Consult the WCO Harmonized System Explanatory Notes for Heading 2920 for detailed guidance. If the product is a mixture or preparation, apply General Interpretative Rules 3(b) or 3(c) to determine the correct heading, which will likely be outside Chapter 29. For definitive classification, consider requesting a binding ruling from the relevant customs authority, such as U.S. Customs and Border Protection (CBP) or the EU TARIC system.

FAQ
What are the typical Most Favored Nation (MFN) import duty rates for products classified under HS 2920.19 in major markets?
For HS 2920.19, 'Esters of other inorganic acids of non-metals (excluding esters of hydrogen halides) and their salts; their halogenated, sulphonated, nitrated or nitrosated derivatives: Other', MFN duty rates can vary significantly by importing country. For example, the United States (USITC) generally applies a 3.5% ad valorem duty rate for products under HTSUS 2920.19.00.00. The European Union (TARIC) typically applies a 6.5% ad valorem duty rate for CN 2920 19 00. The United Kingdom Global Tariff (UKGT) also applies a 6.5% ad valorem duty rate for commodity code 2920 19 00 00. Importers should always verify the specific duty rate applicable to their destination country using the official tariff database for that jurisdiction.
Which preferential trade agreements offer duty-free access for goods classified under HS 2920.19, and what documentation is required?
Many preferential trade agreements provide duty-free access for products under HS 2920.19, provided the goods meet the respective rules of origin. For imports into the United States, duty-free treatment (0.00% ad valorem) may be available under agreements such as the USMCA (Canada, Mexico), CAFTA-DR (Dominican Republic, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua), and various FTAs with countries like Australia (AU), Chile (CL), Colombia (CO), Israel (IL), Korea (KR), Panama (PA), Peru (PE), and Singapore (SG). To claim preferential duty rates, importers typically need to provide a valid Certificate of Origin (e.g., USMCA Certificate of Origin, Form A for GSP, or a declaration of origin) that explicitly states the goods originate in a qualifying country and meet the specific origin criteria of the agreement. Customs brokers should ensure all origin criteria, including regional value content or change in tariff heading rules, are met.
What are the key classification criteria for distinguishing products under HS 2920.19 from other subheadings within Chapter 29?
HS 2920.19 is the 'Other' subheading for 'Esters of other inorganic acids of non-metals (excluding esters of hydrogen halides) and their salts; their halogenated, sulphonated, nitrated or nitrosated derivatives'. The primary classification criteria revolve around the chemical structure of the compound. Goods must be esters of inorganic acids of non-metals, excluding those of hydrogen halides (which fall under 2919). This subheading captures a diverse range of chemical compounds that do not fit into the more specific subheadings of 2920.11 (Thiophosphoric esters and their salts) or 2920.12 (Phosphites and their salts; phosphonates and their salts). Importers and customs brokers must ensure the chemical name and CAS number precisely match the description to avoid misclassification. Reference to the WCO Explanatory Notes for Chapter 29 is crucial for accurate interpretation.
Are there any specific import documentation or regulatory requirements, beyond standard customs declarations, for chemicals under HS 2920.19?
Yes, beyond standard customs declarations (e.g., commercial invoice, packing list, bill of lading/air waybill), chemicals classified under HS 2920.19 may be subject to additional regulatory requirements depending on their specific chemical properties and intended use. These can include: 1. Safety Data Sheets (SDS): Required for hazardous chemicals in most jurisdictions. 2. Chemical Registration: Compliance with chemical inventory regulations such as TSCA (Toxic Substances Control Act) in the US, REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) in the EU, or similar national chemical control laws. 3. Permits/Licenses: Certain chemicals may require import permits from environmental protection agencies or health authorities. 4. End-Use Certificates: If the chemical has dual-use potential (civilian and military applications), an end-use certificate may be required. Importers should consult with regulatory bodies in the destination country to determine all applicable requirements prior to shipment.
