HS 283692 Strontium carbonate
Quick Answer: HS 283692 specifically covers strontium carbonate, a chemical compound primarily used in the production of ceramic magnets, pyrotechnics, and specialty glass for cathode ray tubes. Importers and exporters should note varying duty rates across major jurisdictions. The UK applies a 4.00% ad valorem duty. The EU's TARIC system lists a 5.50% ad valorem rate. For the United States, the general Most Favored Nation (MFN) duty rate is 4.2% ad valorem, but certain preferential trade agreements (e.g., with Australia, Chile, Korea, Singapore) allow for duty-free entry. Customs brokers should verify specific country-of-origin eligibility for these preferential rates to optimize import costs.

How to Classify This HS Code?
What products does HS 283692 cover?
This subheading covers strontium carbonate (SrCO3), a chemical compound specifically identified within Heading 2836, which encompasses carbonates; peroxocarbonates (percarbonates); commercial ammonium carbonate containing ammonium carbamate. According to the Harmonized System Nomenclature published by the World Customs Organization (WCO) and reflected in national tariffs such as the USITC Harmonized Tariff Schedule of the United States (HTSUS) and the EU TARIC, this specific subheading is reserved solely for strontium carbonate. It is a white, odorless, tasteless powder primarily used in the production of ceramic magnets, pyrotechnics, and as a raw material in the glass and ceramic industries, distinguishing it from other carbonates listed under different subheadings within Heading 2836.
What falls outside HS 283692?
The following products are excluded from HS 283692: other carbonates of strontium, such as strontium bicarbonate, which would typically fall under a different subheading if specifically provided for, or under a residual "other" category within Heading 2836 or Chapter 28. Furthermore, strontium compounds that are not carbonates, for instance, strontium nitrate (HS 2834.29.50) or strontium chloride (HS 2827.39.90), are explicitly excluded as they belong to different chemical families and are classified under their respective headings in Chapter 28. Mixtures containing strontium carbonate where the strontium carbonate is not the predominant component or does not impart the essential character of the mixture may also be classified elsewhere, often under Chapter 38 if they are prepared for specific uses.
What are common classification mistakes for HS 283692?
A common error is misclassifying other strontium compounds or mixtures containing strontium carbonate under HS 283692, rather than their correct specific subheadings or residual categories. Importers might incorrectly apply this code to strontium nitrate or strontium chloride, failing to adhere to General Interpretative Rule (GRI) 1, which dictates classification according to the terms of the headings and any relative section or chapter notes. Another mistake involves classifying mixtures where strontium carbonate is present but not the essential character-imparting component; in such cases, GRI 3(b) or 3(c) might apply, leading to classification based on the material or component that gives the mixture its essential character, or under the heading that occurs last in numerical order among those equally meriting consideration.
How should importers classify products under HS 283692?
The correct procedure for classifying products under HS 283692 involves first confirming that the product is indeed pure strontium carbonate (SrCO3) and not a mixture or another strontium compound. Importers and customs brokers should meticulously review the product's chemical composition, typically through a Certificate of Analysis (CoA) or Safety Data Sheet (SDS), to verify its identity. Adherence to General Interpretative Rule 1 is paramount, ensuring that the product precisely matches the description "Strontium carbonate" under Heading 2836. If there is any ambiguity, consulting the WCO Explanatory Notes for Heading 2836 and relevant national tariff guidance, such as USITC rulings or EU TARIC notes, is advisable to ensure accurate and compliant classification, thereby avoiding potential penalties or delays.

FAQ
What are the standard Most Favored Nation (MFN) import duty rates for Strontium Carbonate (HS 2836.92) in major markets?
The MFN duty rates for Strontium Carbonate (HS 2836.92) vary by importing country. For example, the United States generally applies a 4.2% ad valorem duty rate under the Harmonized Tariff Schedule of the United States (HTSUS). The European Union's TARIC database typically shows an MFN duty rate of 5.50% ad valorem. The UK Global Tariff also lists a 5.50% ad valorem duty. It is crucial for importers to verify the exact rate applicable in their destination country using the official tariff database (e.g., USITC HTSUS, EU TARIC, UK Trade Tariff).
Are there any preferential duty rates available for Strontium Carbonate (HS 2836.92) under free trade agreements or special programs?
Yes, preferential duty rates, often 'Free' (0% ad valorem), are available for Strontium Carbonate (HS 2836.92) when originating from countries with which the importing nation has a Free Trade Agreement (FTA) or other preferential trade programs. For instance, in the U.S., imports from 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) may qualify for duty-free entry under their respective FTAs, provided all rules of origin are met. Importers should consult the specific FTA text and provide proper documentation, such as a certificate of origin, to claim these preferential rates.
What are the key classification criteria for ensuring Strontium Carbonate is correctly assigned to HS 2836.92?
The classification of Strontium Carbonate under HS 2836.92 is based on its chemical composition and identity. Heading 2836 covers 'Carbonates; peroxocarbonates (percarbonates); commercial ammonium carbonate containing ammonium carbamate.' Subheading 2836.92 specifically identifies 'Strontium carbonate.' Key criteria for classification include: 1. Chemical Identity: The product must be chemically identifiable as strontium carbonate (SrCO3). 2. Purity: While commercial grades are common, the primary chemical identity must be strontium carbonate. Impurities or mixtures that alter its fundamental character could lead to classification elsewhere. 3. Form: It typically appears as a white powder. Importers should ensure that the product description on commercial invoices and other documentation clearly states 'Strontium Carbonate' to facilitate accurate classification by customs authorities, referencing Chapter 28, Note 1 for inorganic chemicals.
What specific documentation is typically required for importing Strontium Carbonate (HS 2836.92)?
Standard import documentation for Strontium Carbonate (HS 2836.92) includes a commercial invoice, packing list, and bill of lading or air waybill. To claim preferential duty rates under an FTA, a valid Certificate of Origin (e.g., U.S.MCA Certificate of Origin, KORUS FTA Certificate of Origin) or a declaration of origin from the producer/exporter is essential. Depending on the end-use or specific national regulations, additional documentation may be required, such as a Safety Data Sheet (SDS) for hazardous materials assessment, or permits/licenses if the substance is subject to specific chemical control regulations (e.g., REACH in the EU, TSCA in the US, although Strontium Carbonate is generally not highly regulated in this regard). Importers should always confirm specific requirements with their customs broker or the relevant customs authority in the importing country.
