HS 293110 Tetramethyl lead and tetraethyl lead
Quick Answer: HS code 293110 covers organo-inorganic compounds, specifically tetramethyl lead and tetraethyl lead. These are lead-based antiknock agents historically used as fuel additives in gasoline. Due to environmental and health concerns, their use has been largely phased out globally, leading to significantly reduced trade volumes. For importers and customs brokers, understanding the current regulatory landscape is crucial. In the UK, the Most Favoured Nation (MFN) duty rate is 6.00% ad valorem. The EU applies an MFN rate of 6.50% ad valorem. The US MFN rate is 3.7% ad valorem, with many preferential trade agreements (e.g., under GSP, CAFTA-DR, KORUS) offering duty-free treatment, while a 25% rate applies to goods from certain countries under Section 301 tariffs. Importers must verify origin and applicable trade programs.

How to Classify This HS Code?
What products does HS 293110 cover?
This subheading covers two specific organo-inorganic compounds: tetramethyl lead and tetraethyl lead. These are distinct chemical compounds where lead atoms are directly bonded to carbon atoms within methyl or ethyl groups, respectively. According to the Harmonized System Nomenclature, as interpreted by the World Customs Organization (WCO), Heading 2931 encompasses "Other organo-inorganic compounds." Subheading 293110 specifically isolates these two historically significant antiknock agents for internal combustion engines. The USITC Harmonized Tariff Schedule (HTS) and the EU TARIC system both precisely define this subheading to include only these two lead-based organic compounds, which are characterized by their specific chemical structures and properties.
What falls outside HS 293110?
The following products are excluded from HS 293110: any other organo-lead compounds not specifically named, and inorganic lead compounds. For instance, lead acetate, while containing lead, is an organic salt and would typically classify under Heading 2915 as an acetic acid derivative, not as an organo-inorganic compound of Heading 2931. Similarly, lead oxides (e.g., lead monoxide, red lead) are inorganic compounds and fall under Chapter 28, specifically Heading 2824. Mixtures containing tetramethyl lead or tetraethyl lead, where these compounds are not the predominant component or are in preparations for specific uses, might also classify elsewhere based on the nature of the mixture or preparation, such as under Chapter 38 for miscellaneous chemical products.
What are common classification mistakes for HS 293110?
A common error is misclassifying other organo-lead compounds or lead-containing mixtures under HS 293110. This subheading is highly specific to *only* tetramethyl lead and tetraethyl lead. Importers might incorrectly apply this code to other organo-lead compounds that fall under the broader Heading 2931 but are not these two specific chemicals, or even to inorganic lead compounds. Adherence to General Interpretative Rule (GRI) 1, which states that classification is determined according to the terms of the headings and any relative section or chapter notes, is crucial. The precise wording "Tetramethyl lead and tetraethyl lead" leaves no room for other substances, emphasizing the specificity of this particular subheading within the broader organo-inorganic compounds category.
How should importers classify products under HS 293110?
The correct procedure for classifying products under HS 293110 involves a rigorous chemical identification process. Importers and customs brokers must ensure that the product is unequivocally either tetramethyl lead or tetraethyl lead, and not a mixture, preparation, or another organo-lead compound. This requires obtaining a detailed Certificate of Analysis (CoA) or Safety Data Sheet (SDS) from the manufacturer, clearly stating the chemical name, CAS number, and molecular structure. Cross-referencing these details with the WCO HS Explanatory Notes for Heading 2931, as well as the specific definitions in the USITC HTS and EU TARIC, will confirm the exact scope. If the product is a mixture, the classification will depend on the predominant component or the function of the mixture, potentially leading to a different heading or chapter based on GRI 3.

FAQ
What is the Most Favored Nation (MFN) import duty rate for HS code 2931.10 ('Tetramethyl lead and tetraethyl lead') in major economies?
The MFN (Most Favored Nation) import duty rates for HS code 2931.10 vary by importing country. For example, the United States applies a rate of 6.5% ad valorem. The European Union's TARIC database indicates a common customs tariff (CCT) rate of 6.5% ad valorem. The United Kingdom Global Tariff (UKGT) also lists a 6.5% ad valorem rate. Other countries may have rates such as 3.7% or 6.0% ad valorem. Importers should always consult the specific tariff schedule of the destination country, such as the USITC Harmonized Tariff Schedule (HTSUS), EU TARIC, or UK Trade Tariff, for the most current and accurate MFN duty rate.
Are there any preferential duty rates available for 'Tetramethyl lead and tetraethyl lead' under HS 2931.10, and how can an importer claim them?
Yes, preferential duty rates, including 'Free' (0%) rates, are available for HS 2931.10 under various Free Trade Agreements (FTAs) or Generalized System of Preferences (GSP) programs. For instance, the United States offers 'Free' duty rates for goods originating from countries such as 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) under specific trade agreements. To claim a preferential duty rate, importers must provide valid documentation, typically a Certificate of Origin (e.g., Form A for GSP, specific FTA certificates), proving that the goods meet the rules of origin requirements of the respective agreement. Customs brokers require this documentation to accurately declare the goods and apply the correct preferential tariff treatment at the time of import.
What are the key classification criteria for 'Tetramethyl lead and tetraethyl lead' under HS code 2931.10, and what distinguishes them from other organo-inorganic compounds?
HS code 2931.10 specifically covers 'Tetramethyl lead and tetraethyl lead'. The classification criteria are based on the chemical identity of these specific organo-lead compounds. These are distinct organo-inorganic compounds where the lead atom is directly bonded to carbon atoms, forming alkyl groups. The key distinction from other organo-inorganic compounds (which fall under other subheadings of HS 2931) is the precise chemical structure and composition, specifically the presence of four methyl or four ethyl groups bonded to a central lead atom. Importers and customs brokers must ensure that the chemical name and CAS (Chemical Abstracts Service) number on the product's Safety Data Sheet (SDS) or Certificate of Analysis (CoA) precisely match these definitions to ensure correct classification under 2931.10, as misclassification can lead to penalties or delays.
What specific documentation is typically required by customs authorities for the import of goods classified under HS 2931.10?
For the import of goods under HS 2931.10 ('Tetramethyl lead and tetraethyl lead'), customs authorities typically require standard import documentation, including: a commercial invoice detailing the goods, value, and parties involved; a packing list; and a bill of lading or air waybill. Due to the nature of these chemical compounds, additional documentation is often critical: a Safety Data Sheet (SDS) providing chemical identification, hazards, and handling instructions; a Certificate of Analysis (CoA) confirming the chemical composition and purity; and potentially an import license or permit if required by national chemical control regulations (e.g., environmental protection agencies or chemical weapons conventions). For preferential duty claims, a valid Certificate of Origin is also mandatory. Importers should verify specific national requirements with their customs broker or the relevant government agencies prior to shipment.
