HS 284530 Lithium enriched in lithium-6 and its compounds
Quick Answer: HS code 284530 covers lithium enriched in the isotope lithium-6, and chemical compounds containing this enriched lithium. This distinct classification differentiates it from natural lithium or unenriched lithium compounds. Importers and exporters should note the varying duty rates across major jurisdictions. For instance, the UK Trade Tariff currently applies a 0.00% duty rate. The EU TARIC system lists a 5.50% ad valorem duty. In the US, the Harmonized Tariff Schedule (HTSUS) indicates a "Free" duty rate for most favored nation (MFN) treatment, but also notes a 25% ad valorem rate under Subchapter III, Chapter 99 for goods of Chinese origin, subject to Section 301 tariffs. Given its strategic importance in nuclear and advanced battery technologies, trade in these products may be subject to specific export controls or licensing requirements beyond standard customs procedures.

How to Classify This HS Code?
What products does HS 284530 cover?
This subheading covers lithium enriched in lithium-6 and its compounds, as defined by the Harmonized System Nomenclature, specifically within Heading 2845 which encompasses isotopes and their compounds, inorganic or organic, of chemical elements. The enrichment process increases the concentration of the isotope lithium-6 beyond its natural abundance, typically for specialized applications such as nuclear fusion research, tritium production, or neutron absorption. Official interpretations from the USITC Harmonized Tariff Schedule and the EU TARIC system confirm that both the enriched elemental lithium and any chemical compounds derived from it, where the lithium component maintains this isotopic enrichment, fall squarely within this classification.
What falls outside HS 284530?
The following products are excluded from HS 284530: naturally occurring lithium and its compounds, which are classified elsewhere, typically under Heading 2825 for lithium oxide and hydroxide, or other specific inorganic compound headings in Chapter 28 if not isotopically enriched. Furthermore, depleted lithium, where the concentration of lithium-6 is reduced below its natural abundance, would also not be classified here, as the subheading specifically requires enrichment in lithium-6. Lithium metal that has not undergone an enrichment process, even if intended for high-purity applications, is also excluded and would typically fall under Heading 2805.
What are common classification mistakes for HS 284530?
A common error is misclassifying naturally occurring lithium or its compounds under HS 284530, failing to recognize that the "enriched in lithium-6" criterion is a strict requirement for this specific subheading. Importers sometimes overlook the isotopic enrichment aspect, assuming that any high-purity lithium or its compounds belong here, which is incorrect. Another mistake involves classifying depleted lithium under this code, despite the clear distinction in the nomenclature. Proper application of General Interpretive Rule (GRI) 1, which dictates classification according to the terms of the headings and any relative section or chapter notes, is crucial to avoid these errors, emphasizing the specific isotopic characteristic.
How should importers classify products under HS 284530?
The correct procedure for classifying products under HS 284530 involves a meticulous review of the product's isotopic composition. Importers and customs brokers must obtain documentation from the manufacturer or supplier explicitly stating that the lithium or its compounds are indeed enriched in lithium-6, specifying the enrichment level. This documentation is critical evidence to support the classification. Subsequently, cross-referencing with the WCO Explanatory Notes for Heading 2845 and consulting the specific national tariff schedules (e.g., USITC HTS or EU TARIC) will confirm the appropriate subheading. Any ambiguity should prompt a request for a binding ruling from the relevant customs authority to ensure compliance and avoid potential penalties.

FAQ
What is the Most Favored Nation (MFN) import duty rate for HS 284530 (Lithium enriched in lithium-6 and its compounds) in major markets?
The MFN import duty rate for HS 284530 varies by importing country. For example, the United States generally applies a 'Free' duty rate (0.00%) under the Harmonized Tariff Schedule of the United States (HTSUS) for MFN countries. The European Union's TARIC database also indicates a 0.00% ad valorem duty rate for MFN imports. However, other countries may apply different rates, such as 5.50% or 25%. Importers should always consult the specific tariff schedule of the destination country (e.g., USITC HTSUS, EU TARIC, UK Trade Tariff) for the most accurate and up-to-date information.
What are the key classification criteria for products under HS 284530, specifically regarding 'enriched in lithium-6'?
HS 284530 specifically covers 'Lithium enriched in lithium-6 and its compounds'. The critical classification criterion is the isotopic enrichment level of lithium-6. For a product to be classified under this subheading, the lithium component must have a higher concentration of the lithium-6 isotope than its natural abundance (approximately 7.5% of total lithium atoms). This distinction is crucial as unenriched lithium and its compounds fall under other headings, such as 2805.40 (Lithium) or other subheadings within Chapter 28 for specific inorganic compounds. Importers must be prepared to provide analytical certificates or statements confirming the isotopic enrichment level to customs authorities.
Are there any preferential duty rates available for HS 284530 under common trade agreements?
Yes, preferential duty rates may be available for HS 284530 depending on the country of origin and the existence of applicable trade agreements. For instance, imports into the United States from countries party to agreements like the USMCA (United States-Mexico-Canada Agreement) or various Free Trade Agreements (FTAs) may qualify for a 0.00% duty rate, provided all rules of origin requirements are met. Similarly, the EU has numerous preferential trade agreements that could offer reduced or zero duties. Importers should verify the specific agreement's rules of origin and ensure proper documentation, such as a certificate of origin, is available to claim preferential treatment. Consulting the relevant trade agreement text and the importing country's tariff schedule is essential.
What specific documentation is typically required by customs for imports of HS 284530?
Beyond standard import documentation (commercial invoice, packing list, bill of lading/air waybill), importers of HS 284530 should anticipate specific requirements due to the nature of the product. Customs authorities may request: 1. Analytical Certificates: To verify the isotopic enrichment level of lithium-6. 2. End-Use Certificates: Depending on the destination country's regulations and the product's potential dual-use applications (e.g., nuclear research), an end-use statement or certificate might be required to confirm the intended application. 3. Export/Import Licenses: Due to its strategic importance, some countries may require specific export licenses from the country of origin or import licenses in the destination country. Importers should consult their customs broker and the relevant national regulatory bodies for precise documentation requirements prior to shipment.
