HS 290129 Other
Quick Answer: HS 2901.29, "Other," covers acyclic hydrocarbons that are unsaturated and not elsewhere specified within subheading 2901.2. This includes a diverse range of organic chemical compounds, such as certain alkenes and alkynes. For importers and exporters, understanding the specific chemical structure is crucial for accurate classification. Duty rates vary significantly by jurisdiction: the UK and EU generally apply a 0.00% ad valorem duty. In contrast, the US offers a "Free" rate for some entries under this code, but also imposes a 25% ad valorem duty on others, particularly those originating from countries subject to Section 301 tariffs. Importers should verify the specific 10-digit US HTSUS subheading and country of origin to determine the applicable duty rate and any potential trade remedies.

How to Classify This HS Code?
What products does HS 290129 cover?
This subheading covers acyclic hydrocarbons that are unsaturated, other than ethylene, propylene, butenes, and butadiene. Specifically, HS 2901.29 encompasses a diverse range of straight-chain or branched-chain organic compounds containing at least one carbon-carbon double bond (alkenes) or triple bond (alkynes), provided they are not specifically enumerated in other subheadings under Heading 2901. This includes compounds like pentenes, hexenes, heptenes, octenes, and their isomers, as well as acetylenic hydrocarbons such as propyne or butyne, as defined by the World Customs Organization (WCO) Harmonized System Explanatory Notes and reflected in the USITC Harmonized Tariff Schedule (HTS) and EU TARIC classification.
What falls outside HS 290129?
The following products are excluded from HS 290129: ethylene (2901.21), propylene (2901.22), butenes (2901.23), and 1,3-butadiene (2901.24), which are specifically provided for in their respective subheadings due to their significant industrial importance. Additionally, cyclic hydrocarbons, whether saturated or unsaturated, are excluded and fall under HS 2902. For example, cyclohexane (saturated cyclic) is classified under 2902.11, and benzene (unsaturated cyclic) is classified under 2902.20. Hydrocarbons that have undergone further chemical modification, such as halogenation or oxygenation, are also excluded and are classified in subsequent chapters or headings based on their principal functional group, as they are no longer merely hydrocarbons.
What are common classification mistakes for HS 290129?
A common error is misclassifying specific unsaturated acyclic hydrocarbons that have their own dedicated subheadings, such as butenes, under "other." Importers sometimes overlook the specific provisions for major industrial chemicals, leading to incorrect classification under 2901.29 when a more specific 6-digit code exists, violating General Interpretative Rule (GRI) 6, which mandates classification at the most specific subheading level. Another mistake involves classifying mixtures of hydrocarbons where the predominant component is not an "other" unsaturated acyclic hydrocarbon, or where the mixture contains significant quantities of saturated or cyclic hydrocarbons, requiring careful analysis of the chemical composition and application of GRI 3(b) if it's a mixture or composite good.
How should importers classify products under HS 290129?
The correct procedure for classifying products under HS 290129 involves a systematic approach. First, verify that the product is indeed an acyclic hydrocarbon. Second, confirm that it contains at least one carbon-carbon double or triple bond, making it unsaturated. Third, and critically, ensure the product is *not* ethylene, propylene, butenes, or 1,3-butadiene, as these have specific subheadings. Importers and customs brokers should obtain a detailed Certificate of Analysis (CoA) or Safety Data Sheet (SDS) from the manufacturer, clearly identifying the chemical name, CAS number, and molecular structure. If there is any doubt, consider requesting a binding ruling from the relevant customs authority (e.g., CBP in the US, national customs authorities in the EU) to ensure compliance and avoid potential penalties.

FAQ
What is the Most Favored Nation (MFN) import duty rate for products classified under HS 2901.29 in major markets?
For products classified under Harmonized System (HS) subheading 2901.29, which covers 'Acyclic hydrocarbons; unsaturated; other', the Most Favored Nation (MFN) import duty rates can vary. For instance, the United States generally applies a 'Free' duty rate (0.00% ad valorem) to goods under this subheading, as per the USITC Harmonized Tariff Schedule (HTS). Similarly, the European Union's TARIC database also indicates a '0.00%' ad valorem duty rate for most imports under this code. However, it is crucial to verify the specific country of origin and destination, as certain trade remedies or specific national tariffs might apply. Importers should consult the official tariff schedule of the importing country (e.g., USITC HTS, EU TARIC, UK Trade Tariff) for the most current and precise information.
Are there any preferential duty rates available for HS 2901.29 under common trade agreements?
Yes, preferential duty rates are often available for products classified under HS 2901.29, depending on the country of origin and the applicable free trade agreements (FTAs). For example, under agreements like the United States-Mexico-Canada Agreement (USMCA), goods originating from Mexico or Canada and meeting the rules of origin criteria are typically eligible for a 'Free' (0.00%) duty rate when imported into the U.S. Similarly, the EU has numerous FTAs (e.g., with Japan, South Korea, Canada) that may grant preferential '0.00%' duty rates. Importers must ensure they have the necessary documentation, such as a certificate of origin, to claim these preferential tariffs. Always consult the specific trade agreement's text and the importing country's customs regulations for origin requirements.
What are the key classification criteria for 'Other' unsaturated acyclic hydrocarbons under HS 2901.29?
HS 2901.29 is the residual subheading for 'Other' unsaturated acyclic hydrocarbons, meaning it covers those not specifically provided for in subheadings 2901.21 through 2901.24 (e.g., ethylene, propylene, butenes, butadiene). The primary classification criteria revolve around the chemical structure: the substance must be an acyclic hydrocarbon (containing only carbon and hydrogen atoms, in an open-chain structure) and must contain at least one carbon-carbon double or triple bond (unsaturated). If the hydrocarbon is cyclic, it would fall under HS 2902. If it is saturated (only single carbon-carbon bonds), it would fall under HS 2901.10. Importers should have detailed chemical specifications, including CAS numbers and chemical names, to ensure accurate classification. WCO Explanatory Notes for Chapter 29 provide further guidance.
What documentation is typically required for importing goods classified under HS 2901.29?
Importers of products under HS 2901.29 generally need to provide standard customs documentation, which includes a commercial invoice, packing list, and bill of lading or air waybill. For chemical products, additional documentation is often critical. This may include a Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) to provide information on the substance's properties and handling. If claiming preferential duty rates under a free trade agreement, a certificate of origin or a declaration of origin is mandatory. Depending on the specific chemical and its end-use, permits or licenses from regulatory bodies (e.g., EPA in the U.S., ECHA in the EU) might be required, especially for controlled substances or those subject to specific environmental regulations. Customs brokers can assist in identifying all necessary permits.
Are there any specific import restrictions or regulatory considerations for unsaturated acyclic hydrocarbons under HS 2901.29?
While HS 2901.29 covers a broad range of 'other' unsaturated acyclic hydrocarbons, specific import restrictions or regulatory considerations can apply depending on the exact chemical compound. Some hydrocarbons may be subject to environmental regulations concerning volatile organic compounds (VOCs) or specific chemical control laws (e.g., TSCA in the U.S., REACH in the EU). For instance, certain isomers or derivatives might be precursors for controlled substances or have specific industrial applications that require monitoring. Importers should verify if the specific chemical within this subheading is listed on any national or international control lists, such as those related to ozone-depleting substances or hazardous chemicals. Consulting with regulatory affairs specialists or customs brokers experienced in chemical imports is highly recommended to ensure compliance.
