HS 290551 Halogenated, sulphonated, nitrated or nitrosated derivatives of acyclic alcohols

Quick Answer: HS code 290551 covers halogenated, sulphonated, nitrated, or nitrosated derivatives of acyclic alcohols. In simpler terms, this includes chemically modified acyclic alcohols where hydrogen atoms have been replaced by halogens (like chlorine or bromine), or by sulphonate, nitrate, or nitrosate groups. Examples include chloral hydrate or trichloroethanol. For importers and exporters, understanding the specific chemical modification is crucial for correct classification. Duty rates vary significantly: the UK and EU generally apply a 0.00% ad valorem duty. In the US, while a "Free" rate is common, certain specific derivatives within this heading can face a 39% ad valorem duty, as per the USITC Harmonized Tariff Schedule. Importers should verify the exact chemical structure against the tariff schedule to avoid misclassification and unexpected costs.

How to Classify This HS Code?

What products does HS 290551 cover?

This subheading covers halogenated, sulphonated, nitrated, or nitrosated derivatives of acyclic alcohols, as defined by the World Customs Organization's Harmonized System Nomenclature and further detailed in the USITC Harmonized Tariff Schedule of the United States (HTSUS) and the EU TARIC system. Specifically, it encompasses organic chemical compounds where an acyclic alcohol has undergone a chemical modification involving the introduction of a halogen atom (e.g., fluorine, chlorine, bromine, iodine), a sulphonyl group (-SO2OH), a nitro group (-NO2), or a nitroso group (-NO). These derivatives retain the fundamental acyclic alcohol structure but possess these additional functional groups, altering their chemical properties and applications.

What falls outside HS 290551?

The following products are excluded from HS 290551: derivatives of cyclic alcohols, which are classified elsewhere in Chapter 29, typically under headings 2906 or 2907, depending on their specific structure. Furthermore, ethers, peroxides, epoxide alcohols, acetals and hemiacetals, and their halogenated, sulphonated, nitrated or nitrosated derivatives are specifically excluded from Heading 2905 by Note 4 to Chapter 29, and would be classified under Heading 2909. For example, chloral hydrate (2,2,2-trichloroethane-1,1-diol) is not classified here despite being halogenated, as it is an aldehyde hydrate, falling under Heading 2912.

What are common classification mistakes for HS 290551?

A common error is misclassifying compounds that are derivatives of cyclic alcohols or other functional groups, rather than strictly acyclic alcohols. Importers sometimes overlook the specific exclusions outlined in Chapter 29 Notes, particularly Note 4, which directs certain derivatives of ethers, peroxides, and epoxides elsewhere. Another frequent mistake involves failing to correctly identify the primary functional group of a complex molecule. For instance, a compound that is both an acyclic alcohol derivative and an ether, where the ether function predominates, would be classified under Heading 2909, not 2905, in accordance with General Interpretative Rule (GRI) 3(a) and Chapter Notes.

How should importers classify products under HS 290551?

The correct procedure for classifying products under HS 290551 involves a rigorous analysis of the chemical structure to confirm it is an acyclic alcohol derivative with only halogen, sulphonyl, nitro, or nitroso modifications. Importers and customs brokers should first verify that the compound is indeed an acyclic alcohol and not a cyclic alcohol or another organic function. Next, confirm the presence of only the specified derivative groups. Consult the WCO Explanatory Notes for Heading 2905 and the specific legal notes to Chapter 29, particularly Note 4, to rule out exclusions. If uncertainty persists, obtaining a binding ruling from the relevant customs authority (e.g., CBP in the US, HMRC in the UK, or national customs in the EU) is highly recommended to ensure compliance and avoid potential penalties.

FAQ

What are the standard Most Favored Nation (MFN) duty rates for products classified under HS 2905.51 in major markets?

The MFN duty rates for 'Halogenated, sulphonated, nitrated or nitrosated derivatives of acyclic alcohols' (HS 2905.51) vary significantly by importing country. For example, the United States generally applies a 'Free' duty rate (0.00% ad valorem) under the Harmonized Tariff Schedule of the United States (HTSUS). The European Union's TARIC database also typically indicates a 0.00% ad valorem duty rate for most MFN imports. However, other countries, such as certain developing nations or those with specific industrial protection policies, might apply higher rates, potentially up to 39% ad valorem. Importers should always verify the exact MFN duty rate for their specific destination country using the official tariff database (e.g., USITC HTSUS, EU TARIC, UK Trade Tariff) at the time of import.

How do I correctly classify a chemical under HS 2905.51, and what are the key classification criteria?

Classification under HS 2905.51 requires the chemical to be an acyclic alcohol derivative that has undergone halogenation, sulphonation, nitration, or nitrosation. The primary criteria are: 1. Acyclic Alcohol Base: The parent compound must be an acyclic alcohol (e.g., methanol, ethanol, propanol). 2. Derivatization: It must be a derivative formed by introducing halogen atoms (fluorine, chlorine, bromine, iodine), sulphonic acid groups (-SO3H), nitro groups (-NO2), or nitroso groups (-NO) into the molecular structure. It's crucial to distinguish these from simple esters or ethers of acyclic alcohols, which fall under different headings. For instance, chloral hydrate (trichloroacetaldehyde monohydrate) is a halogenated derivative of an acyclic alcohol and would typically fall here. Referencing the Explanatory Notes to Chapter 29 of the Harmonized System by the World Customs Organization (WCO) provides detailed guidance and examples for precise classification.

Are there any preferential duty rates available for HS 2905.51 under common free trade agreements?

Yes, preferential duty rates, often 'Free' (0.00% ad valorem), are frequently available for HS 2905.51 under various free trade agreements (FTAs) and Generalized System of Preferences (GSP) schemes, provided the product meets the specific Rules of Origin. For instance, imports into the United States from FTA partners like Mexico (USMCA), South Korea (KORUS FTA), or Australia (AUSFTA) would generally qualify for a 0.00% preferential duty rate if originating in those countries. Similarly, imports into the EU from GSP beneficiary countries or FTA partners (e.g., Japan, Canada) may also benefit from reduced or zero duties. Importers must ensure they have the correct origin documentation, such as a certificate of origin, to claim these preferential rates. Always consult the specific FTA text or GSP regulations for the importing country to confirm eligibility and documentation requirements.

What specific documentation is required for importing chemicals under HS 2905.51, beyond standard customs declarations?

Beyond the standard commercial invoice, packing list, and bill of lading/air waybill, importing chemicals under HS 2905.51 may require additional documentation due to their chemical nature and potential regulatory controls. Key documents often include: 1. Safety Data Sheet (SDS): Essential for hazard communication and often required by customs or chemical regulatory agencies. 2. Certificate of Analysis (CoA): Verifies the chemical composition, purity, and specifications of the imported product. 3. Import Licenses/Permits: Depending on the specific chemical and its end-use, certain countries may require pre-import permits from chemical control authorities (e.g., for precursors, controlled substances, or chemicals subject to environmental regulations). 4. Origin Certificates: Necessary to claim preferential duty rates under FTAs or GSP schemes. Importers should verify all specific national chemical import regulations and licensing requirements for their destination country well in advance of shipment.
