HS 282580 Antimony oxides
Quick Answer: HS code 282580 specifically covers "Antimony oxides," which are inorganic chemical compounds of antimony and oxygen. The primary product under this classification is antimony trioxide (Sb2O3), a white powder widely used as a flame retardant in plastics, textiles, and rubber, as well as a opacifier in ceramics and glass. Importers and customs brokers should note the varying duty rates: the UK applies a 4.00% ad valorem duty, the EU's TARIC system shows a 5.50% ad valorem rate, while the US imposes a specific duty of 4.4¢/kg, with some originating goods potentially qualifying for duty-free treatment under various trade agreements. Accurate classification is crucial to ensure compliance and optimize duty costs, particularly given the different duty calculation methods (ad valorem vs. specific duty).

How to Classify This HS Code?
What products does HS 282580 cover?
This subheading covers antimony oxides, which are inorganic chemical compounds containing antimony and oxygen. Specifically, it encompasses various forms such as antimony trioxide (Sb2O3), antimony tetroxide (Sb2O4), and antimony pentoxide (Sb2O5). These oxides are primarily used as flame retardants in plastics, textiles, and rubber, as catalysts, and in the production of ceramics and glass. The WCO Harmonized System Explanatory Notes for Chapter 28 confirm that this subheading is dedicated to the specific chemical compounds of antimony oxides, distinguishing them from other antimony compounds or metallic antimony. Both the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC system align with this definition, classifying these pure chemical compounds here.
What falls outside HS 282580?
The following products are excluded from HS 282580: metallic antimony, which is classified under HS 8110.10.00, and antimony sulfides, which fall under HS 2830.90.00. Additionally, mixtures containing antimony oxides where the antimony oxide is not the predominant component, or where the mixture constitutes a preparation for a specific use (e.g., a prepared flame retardant compound containing other active ingredients), might be classified elsewhere, often under Chapter 38 or a more specific heading depending on their composition and function. For instance, a prepared pigment containing antimony oxides would likely be classified under Chapter 32. Antimony compounds other than oxides are also excluded, such as antimony halides or antimonates, which are classified in other relevant subheadings within Chapter 28 based on their chemical structure.
What are common classification mistakes for HS 282580?
A common error is misclassifying mixtures containing antimony oxides as pure antimony oxides under HS 282580. Importers often overlook the distinction between a pure chemical compound and a preparation or mixture. For example, a flame retardant masterbatch containing antimony trioxide dispersed in a polymer matrix should not be classified here, as it is a preparation, not a pure oxide. This mistake often violates 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, and GRI 3(b) for mixtures. Another error involves confusing antimony oxides with other antimony compounds, such as antimony sulfides, leading to incorrect duty rates and regulatory compliance issues.
How should importers classify products under HS 282580?
The correct procedure for classifying products under HS 282580 involves verifying the chemical identity and purity of the product. Importers and customs brokers should obtain a Certificate of Analysis (CoA) or Safety Data Sheet (SDS) from the manufacturer to confirm that the product is indeed an antimony oxide (e.g., Sb2O3, Sb2O4, or Sb2O5) and not a mixture or another antimony compound. If the product is a pure antimony oxide, it correctly falls under HS 282580. If it is a mixture or preparation, further analysis using GRI 3(b) or 3(c) will be necessary to determine the appropriate heading. Consulting the WCO Explanatory Notes for Chapter 28 and specific national tariff guidance from sources like the USITC HTS or EU TARIC is crucial for accurate classification and ensuring compliance with all import regulations and duty obligations.

FAQ
What are the typical Most Favored Nation (MFN) import duty rates for Antimony Oxides (HS 2825.80) in major markets?
The MFN duty rates for Antimony Oxides (HS 2825.80) vary by importing country. For example, the United States generally applies a rate of 3.5% ad valorem under the Harmonized Tariff Schedule of the United States (HTSUS). The European Union's TARIC database indicates a common customs duty of 5.5% ad valorem. The UK Global Tariff also lists a 5.5% ad valorem duty. It is crucial for importers to verify the specific duty rate applicable to their destination country using the official tariff schedules (e.g., USITC HTSUS, EU TARIC, UK Trade Tariff).
Are there any preferential duty rates available for Antimony Oxides (HS 2825.80) under common trade agreements?
Yes, preferential duty rates, including duty-free treatment, may be available for Antimony Oxides (HS 2825.80) depending on the country of origin and the importing country's trade agreements. For instance, under the United States-Mexico-Canada Agreement (USMCA), goods originating from Mexico or Canada are typically duty-free when imported into the U.S. Similarly, the EU has numerous free trade agreements (FTAs) that could grant preferential treatment. Importers should consult the specific rules of origin for relevant trade agreements (e.g., USMCA, GSP, EU FTAs) and ensure proper documentation, such as a certificate of origin, is provided to claim preferential tariffs.
What are the key classification criteria for Antimony Oxides under HS 2825.80?
HS code 2825.80 specifically covers 'Hydrazine and hydroxylamine and their inorganic salts; other inorganic bases; other metal oxides, hydroxides and peroxides.' Within this, 2825.80 is dedicated to 'Antimony oxides.' The primary classification criterion is the chemical composition, specifically identifying the substance as an oxide of antimony (e.g., antimony trioxide, antimony pentoxide). It is important to ensure the product is indeed an antimony oxide and not a compound of antimony with other elements that would fall under a different heading (e.g., antimony sulfides in Chapter 28, or antimony alloys in Chapter 81). The WCO Explanatory Notes for Chapter 28 provide further guidance on the scope of inorganic chemicals.
What specific documentation is typically required for importing Antimony Oxides (HS 2825.80)?
Standard import documentation for Antimony Oxides (HS 2825.80) includes a commercial invoice, packing list, bill of lading or air waybill, and potentially a certificate of origin if preferential duty rates are claimed. Due to the nature of antimony compounds, additional regulatory documentation may be required. For example, a Safety Data Sheet (SDS) is often mandatory for hazardous materials. Depending on the specific use or concentration, importers may need to comply with chemical control regulations such as TSCA in the U.S., REACH in the EU, or similar national regulations, which might necessitate specific permits or declarations. Customs brokers can advise on country-specific requirements.
