HS 292029 Other
Quick Answer: HS code 292029, "Other," encompasses a diverse range of organic esters of phosphoric acid and their salts, not specifically classified elsewhere within heading 2920. This includes various phosphate esters used in flame retardants, plasticizers, and hydraulic fluids. For importers and customs brokers, understanding the specific chemical composition is crucial for accurate classification. Key duty rates vary significantly: the UK generally applies a 6.00% ad valorem duty, while the EU imposes a 6.50% ad valorem rate. The US tariff for this subheading is 3.7% ad valorem, with numerous preferential duty-free rates available under various Free Trade Agreements (e.g., A, AU, CL, KR, SG). Importers should verify eligibility for these programs, as non-qualifying goods face the 3.7% rate, or potentially a 25% rate under specific trade measures. Due diligence in product identification and origin verification is essential to optimize duty costs and ensure compliance.

How to Classify This HS Code?
What products does HS 292029 cover?
This subheading covers other esters of phosphoric acid (phosphates), their salts, and their halogenated, sulfonated, nitrated, or nitrosated derivatives, not elsewhere specified or included within heading 2920. Specifically, it acts as a residual category for organic phosphorus esters that do not fall under the more specific subheadings like 2920.21 (Trimethyl phosphite) or 2920.24 (Tris(2-chloroethyl) phosphate). Examples include various alkyl phosphates, aryl phosphates, and mixed alkyl-aryl phosphates, provided they meet the chemical structure requirements of heading 2920 as defined by the World Customs Organization (WCO) Harmonized System Explanatory Notes and are not explicitly covered by other subheadings within 2920. The USITC Harmonized Tariff Schedule and EU TARIC further confirm this residual scope.
What falls outside HS 292029?
The following products are excluded from HS 292029: Trimethyl phosphite (classified under 2920.21.00), Triethyl phosphite (classified under 2920.22.00), Dimethyl methylphosphonate (classified under 2920.23.00), and Tris(2-chloroethyl) phosphate (classified under 2920.24.00). Furthermore, inorganic phosphates, such as sodium phosphate or calcium phosphate, are excluded as they fall under Chapter 28, specifically heading 2835. Compounds that are not esters of phosphoric acid, even if they contain phosphorus, would also be excluded, such as phosphonates or phosphinates, which are classified elsewhere in Chapter 29 or Chapter 28 depending on their chemical structure and organic/inorganic nature.
What are common classification mistakes for HS 292029?
A common error is misclassifying specific phosphoric acid esters that have their own dedicated subheadings within 2920 into 292029, which is the "other" category. For instance, classifying trimethyl phosphite under 292029 instead of its specific subheading 2920.21.00. Another frequent mistake involves confusing organic phosphorus compounds that are not esters of phosphoric acid with those that are, leading to incorrect classification under heading 2920 at all. Importers might also incorrectly classify complex mixtures containing phosphoric acid esters without properly identifying the principal active ingredient or applying General Interpretative Rule (GRI) 3(b) for mixtures, if applicable, resulting in misclassification of the entire product.
How should importers classify products under HS 292029?
The correct procedure for classifying products under HS 292029 involves a systematic approach. First, confirm that the product is indeed an ester of phosphoric acid, its salts, or its halogenated, sulfonated, nitrated, or nitrosated derivatives, as per the scope of heading 2920. Second, meticulously review all specific subheadings within 2920 (e.g., 2920.21 through 2920.24) to ensure the product is not explicitly covered by one of these more specific codes. If the product is a phosphoric acid ester and does not precisely match any of the more specific subheadings, then and only then should it be classified under 292029. Importers and customs brokers should always consult the WCO HS Explanatory Notes, the USITC Harmonized Tariff Schedule, and the EU TARIC for definitive guidance and consider obtaining a binding ruling for complex or ambiguous cases.

FAQ
What is the Most Favored Nation (MFN) import duty rate for products classified under HS 2920.29 in major markets?
The MFN (Most Favored Nation) import duty rates for products under HS 2920.29 ('Other' esters of phosphoric acid and their salts, including phosphothionates and phosphoramidates) vary by importing country. For example, the general MFN duty rate in the United States is 3.7% ad valorem (USITC Harmonized Tariff Schedule, Chapter 29, Subheading 2920.29.00). In the European Union, the MFN duty rate is 6.5% ad valorem (EU TARIC, Heading 2920 29 00 00). The United Kingdom also applies a 6.5% ad valorem MFN duty rate (UK Trade Tariff, Heading 2920 29 00 00). Importers should always verify the current rate with the official tariff schedule of the destination country.
Which preferential trade agreements offer duty-free access for goods under HS 2920.29?
Many preferential trade agreements provide duty-free access for products classified under HS 2920.29, subject to meeting the specific Rules of Origin. For imports into the United States, duty-free treatment (indicated by 'Free' or 'A', 'AU', 'BH', 'CL', 'CO', 'D', 'E', 'IL', 'JO', 'K', 'KR', 'MA', 'OM', 'P', 'PA', 'PE', 'S', 'SG' in the 'Special' column of the HTSUS) is available under agreements such as the US-Australia FTA, US-Bahrain FTA, US-Chile FTA, US-Colombia TPA, US-Dominican Republic-Central America FTA (CAFTA-DR), US-Israel FTA, US-Jordan FTA, US-Korea FTA, US-Morocco FTA, US-Oman FTA, US-Panama TPA, US-Peru TPA, and the US-Singapore FTA. Importers must ensure they have the correct origin documentation, such as a Certificate of Origin, to claim preferential tariffs.
What are the key classification criteria for distinguishing products under HS 2920.29 from other subheadings?
HS 2920.29 is the 'Other' subheading for esters of phosphoric acid and their salts, including phosphothionates and phosphoramidates, not specifically provided for in other subheadings of 2920. The primary classification criteria involve the chemical structure of the compound. Importers must ensure the product is indeed an ester of phosphoric acid (or a phosphothionate/phosphoramidate) and that it does not fall under more specific subheadings like 2920.11 (Parathion (ISO) and methyl-parathion (ISO)), 2920.19 (Other phosphite esters and their salts), or 2920.90 (Other esters of other inorganic acids of non-metals and their salts; their halogenated, sulphonated, nitrated or nitrosated derivatives). A detailed chemical analysis and understanding of the WCO Explanatory Notes for Chapter 29 are crucial for accurate classification.
Are there any specific documentation requirements or regulatory considerations for importing chemicals under HS 2920.29?
Beyond standard customs documentation (commercial invoice, packing list, bill of lading/airway bill), importing chemicals under HS 2920.29 may involve additional regulatory requirements, depending on the specific chemical and the importing country. Many chemicals in this category could be subject to environmental, health, and safety regulations. For instance, in the United States, certain chemicals may require reporting under the Toxic Substances Control Act (TSCA) administered by the Environmental Protection Agency (EPA). In the EU, REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulations may apply, requiring registration or notification. Importers should consult relevant national chemical control laws and agencies to determine if specific permits, licenses, or declarations (e.g., Safety Data Sheets - SDS) are required prior to shipment.
