HS 291020 Methyloxirane (propylene oxide)
Quick Answer: HS code 291020 specifically covers Methyloxirane, commonly known as Propylene Oxide. This is an important organic chemical primarily used as an intermediate in the production of polyols for polyurethanes, propylene glycol, and various other chemicals. Importers and exporters should note the significant duty rate variations across major markets. The United Kingdom and the European Union apply a 0.00% ad valorem duty rate, reflecting its widespread industrial use. In contrast, the United States imposes a Most Favored Nation (MFN) duty rate of 5.5% ad valorem, though many countries benefit from preferential "Free" duty rates under various Free Trade Agreements (e.g., A, AU, CL, KR). A prohibitive 55% duty applies to non-market economy countries. Accurate classification is crucial to leverage preferential trade agreements and avoid penalties.

How to Classify This HS Code?
What products does HS 291020 cover?
This subheading covers methyloxirane, commonly known as propylene oxide, which is a cyclic ether with the chemical formula C3H6O. As defined by the World Customs Organization's Harmonized System Nomenclature and reflected in the USITC Harmonized Tariff Schedule of the United States (HTSUS) and the EU TARIC, this specific chemical compound is a key intermediate in the production of various industrial chemicals. It is characterized by its three-membered ring containing one oxygen atom and two carbon atoms, with a methyl group attached. Propylene oxide is primarily used in the manufacture of polyether polyols for polyurethanes, propylene glycol, and other derivatives, making it a crucial building block in the chemical industry.
What falls outside HS 291020?
The following products are excluded from HS 291020: other epoxides, even if structurally similar, that do not precisely match the chemical definition of methyloxirane. For instance, ethylene oxide (oxirane), classified under HS 291010, is a distinct chemical compound despite also being a cyclic ether. Similarly, epichlorohydrin (1-chloro-2,3-epoxypropane), which is a halogenated epoxide, falls under HS 291090 as "Other epoxides, epoxyalcohols, epoxyphenols and epoxyethers, with a three-membered ring, and their halogenated, sulphonated, nitrated or nitrosated derivatives." Mixtures containing propylene oxide, but where propylene oxide is not the predominant component or where the mixture has specific functional properties, might also be classified elsewhere, potentially under Chapter 38 if they are preparations.
What are common classification mistakes for HS 291020?
A common error is misclassifying other cyclic ethers or epoxides as methyloxirane due to similar chemical structures or industrial uses. Importers might incorrectly apply HS 291020 to related compounds like ethylene oxide (HS 291010) or other epoxides (HS 291090) if they do not meticulously verify the exact chemical name and structure. This often stems from a failure to strictly adhere to General Interpretative Rule (GRI) 1, which mandates that classification be determined according to the terms of the headings and any relative section or chapter notes. Furthermore, neglecting to consult the WCO Explanatory Notes for Heading 2910, which provide precise definitions and scope for each subheading, can lead to significant classification inaccuracies and potential penalties.
How should importers classify products under HS 291020?
The correct procedure for classifying products under HS 291020 involves a rigorous review of the chemical's identity, ensuring it is precisely methyloxirane (propylene oxide). Importers and customs brokers must obtain and scrutinize the Chemical Abstracts Service (CAS) number (75-56-9 for propylene oxide) and the exact chemical name, formula, and structure from the manufacturer's specifications, safety data sheets (SDS), or certificates of analysis. This information should be cross-referenced with the WCO Harmonized System Nomenclature, the USITC HTSUS, or the EU TARIC to confirm alignment with subheading 291020. Any doubts should prompt consultation with a qualified customs expert or a binding ruling request from the relevant customs authority to ensure compliance and avoid misclassification.

FAQ
What is the Most Favored Nation (MFN) duty rate for HS 2910.20 (Methyloxirane (propylene oxide)) in key markets, and are there any significant variations?
The MFN duty rate for HS 2910.20 can vary significantly by importing country. For instance, the United States generally applies a 'Free' (0.00% ad valorem) MFN duty rate according to the Harmonized Tariff Schedule of the United States (HTSUS). Similarly, the European Union's TARIC database often shows a 0.00% MFN duty rate. However, other countries may apply higher rates; for example, some jurisdictions might apply a 5.5% ad valorem rate, while others, particularly those with protective tariffs for their domestic chemical industries, could have rates as high as 55% ad valorem. Importers must consult the specific tariff schedule of the destination country (e.g., USITC HTSUS, EU TARIC, UK Global Tariff) to ascertain the precise MFN rate applicable at the time of import.
Which preferential trade agreements offer duty-free access for Methyloxirane (propylene oxide) under HS 2910.20, and what documentation is required to claim these benefits?
Many preferential trade agreements provide duty-free access for HS 2910.20. For imports into the United States, for example, Methyloxirane (propylene oxide) may be eligible for duty-free treatment under agreements such as the USMCA (Mexico, Canada), CAFTA-DR (Central America-Dominican Republic), and various Free Trade Agreements (FTAs) with countries like Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Jordan (JO), Korea (KR), Morocco (MA), Oman (OM), Panama (PA), Peru (PE), and Singapore (SG). To claim these preferential rates, importers must provide a valid Certificate of Origin (e.g., USMCA Certificate of Origin, or a free-form certification as allowed by specific FTAs) demonstrating that the product meets the Rules of Origin criteria specified in the respective agreement. Customs brokers require this documentation to correctly declare the goods and apply the preferential tariff treatment.
What are the key classification criteria for ensuring Methyloxirane (propylene oxide) is correctly assigned to HS 2910.20, and what are common misclassification pitfalls?
HS 2910.20 specifically covers 'Methyloxirane (propylene oxide)'. The primary classification criterion is the chemical identity of the substance. Propylene oxide is a cyclic ether with the chemical formula C3H6O and is characterized by its three-membered epoxide ring. It is crucial that the imported product is pure methyloxirane or a mixture where methyloxirane is the essential character. Common misclassification pitfalls include confusing it with other epoxides or derivatives, or with mixtures where propylene oxide is present but not the primary component, which might fall under other subheadings within Chapter 29 (Organic Chemicals) or even Chapter 38 (Miscellaneous Chemical Products) if it's a prepared mixture not elsewhere specified. Importers should rely on chemical analysis reports, Safety Data Sheets (SDS), and product specifications to confirm the exact chemical composition and ensure accurate classification under WCO General Interpretative Rules (GIRs 1 and 6).
Are there any specific import licensing, permits, or regulatory compliance requirements for Methyloxirane (propylene oxide) under HS 2910.20, beyond standard customs procedures?
Yes, beyond standard customs declarations, Methyloxirane (propylene oxide) (HS 2910.20) is a chemical that may be subject to specific regulatory oversight due to its flammability, toxicity, and use as a precursor in various industrial processes. In many countries, it is classified as a hazardous substance. Importers may need to comply with regulations from environmental protection agencies (e.g., EPA in the US), chemical safety authorities, and transportation departments (e.g., DOT for hazardous materials). This could include requirements for special handling, labeling, storage, and transportation permits. Additionally, some jurisdictions may require pre-market notification or registration under chemical control laws (e.g., TSCA in the US, REACH in the EU). Importers and customs brokers should verify all applicable national and regional chemical control laws and obtain any necessary permits or licenses prior to importation to avoid delays or penalties.
