HS 283322 Of aluminium
Quick Answer: HS code 2833.22, "Of aluminium," specifically covers aluminium sulfates, which are inorganic chemical compounds. These products are typically used in water treatment, paper manufacturing, and as mordants in dyeing. For importers and customs brokers, understanding the duty rates is crucial. The UK and EU apply a 0.00% ad valorem duty rate, indicating duty-free entry for these goods. In contrast, the United States imposes a 10% ad valorem duty rate on aluminium sulfates from most countries, though some specific trade agreements or programs may allow for a "Free" duty rate. Importers should verify origin and eligibility for preferential treatment to optimize costs. Exporters should be aware of these varying tariff landscapes to accurately quote landed costs.

How to Classify This HS Code?
What products does HS 283322 cover?
This subheading covers aluminum sulfates, specifically those falling under the broader category of sulfates in Heading 2833, which encompasses sulfates, alums, and peroxosulfates (persulfates). According to the Harmonized System Nomenclature, as interpreted by the World Customs Organization (WCO), and reflected in national tariffs such as the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC, HS 283322 precisely identifies aluminum sulfates. These are chemical compounds consisting of aluminum, sulfur, and oxygen, typically used in water purification, paper manufacturing, and as a mordant in dyeing. The classification is determined by the specific chemical composition where aluminum is the primary cation forming the sulfate salt.
What falls outside HS 283322?
The following products are excluded from HS 283322: aluminum compounds that are not sulfates, such as aluminum oxides (classified under Heading 2818) or aluminum hydroxides (classified under Heading 2818). Additionally, complex aluminum salts that are not primarily sulfates, or mixtures where aluminum sulfate is not the essential character, would be classified elsewhere, potentially under other subheadings within Chapter 28 or even Chapter 38 if they are prepared for specific uses as mixtures. For instance, alums, which are double sulfates of aluminum, are specifically classified under HS 283330, even though they contain aluminum and sulfate, due to their distinct chemical structure and common usage.
What are common classification mistakes for HS 283322?
A common error is misclassifying alums (double sulfates of aluminum) under HS 283322 instead of their specific subheading, HS 283330. Importers sometimes overlook the distinct chemical definition of alums, which, while containing aluminum sulfate, are chemically different and specifically provided for elsewhere. Another mistake involves classifying mixtures containing aluminum sulfate, where the aluminum sulfate is not the essential character, under this subheading. General Interpretative Rule (GRI) 3(b) would typically apply in such cases, directing classification based on the component that gives the mixture its essential character, or GRI 3(c) as a last resort. Careful chemical analysis and reference to the WCO Explanatory Notes are crucial to avoid these errors.
How should importers classify products under HS 283322?
The correct procedure for classifying products under HS 283322 involves first confirming the chemical identity of the product as an aluminum sulfate, ensuring it is not an alum or another aluminum compound. Importers and customs brokers should obtain a Certificate of Analysis (CoA) or Safety Data Sheet (SDS) from the manufacturer, which clearly states the chemical name and composition. This documentation should explicitly confirm the product is aluminum sulfate and not a double sulfate (alum). Subsequently, cross-reference this information with the WCO Harmonized System Explanatory Notes for Heading 2833 and consult national tariff schedules like the USITC HTS or EU TARIC to verify that the specific product description aligns with "Of aluminium" under the sulfates subheading. If there is any doubt, a binding ruling request to the relevant customs authority is recommended.

FAQ
What is the Most Favored Nation (MFN) import duty rate for HS 2833.22 'Of aluminium' in key markets?
The MFN (Most Favored Nation) import duty rate for goods classified under HS 2833.22 'Of aluminium' can vary significantly by importing country. For example, as per the Harmonized Tariff Schedule of the United States (HTSUS) 2024, the general MFN duty rate for 2833.22.00 is 0.00% ad valorem. Similarly, the EU TARIC (Integrated Tariff of the European Union) indicates a MFN duty rate of 0.00% ad valorem for this subheading. However, other countries may apply different rates, such as a 10% ad valorem rate in certain jurisdictions. Importers should always consult the specific national tariff schedule of the country of importation, such as the USITC HTSUS, EU TARIC, or the UK Trade Tariff, for the most accurate and current MFN duty rate applicable to their specific transaction.
What are the primary classification criteria for products under HS 2833.22 'Of aluminium'?
HS 2833.22 specifically covers 'Sulfates; alums; peroxosulfates (persulfates) - Other sulfates - Of aluminium'. The primary classification criterion is the chemical composition: the product must be an aluminum sulfate. This subheading excludes double sulfates (alums) which are classified under 2833.30. Classification hinges on the chemical identity of the substance as a sulfate where aluminum is the cation. Importers should ensure that chemical analysis reports or Certificates of Analysis (CoA) clearly identify the product as an aluminum sulfate to support classification under 2833.22, differentiating it from other metallic sulfates or complex salts.
Are there any preferential duty rates or trade agreements that commonly impact imports of HS 2833.22 'Of aluminium'?
Yes, preferential duty rates can significantly impact imports of HS 2833.22. For instance, under various Free Trade Agreements (FTAs) to which the importing country is a party, goods originating from partner countries may be eligible for a 'Free' (0.00%) duty rate. For example, in the U.S., goods originating from countries with which the U.S. has an FTA (e.g., USMCA, CAFTA-DR, KORUS) may enter duty-free, provided all rules of origin are met. Similarly, within the EU, goods originating from FTA partners or beneficiaries of generalized system of preferences (GSP) schemes may also qualify for reduced or zero duties. Importers should verify the origin of their goods and consult the specific FTA or preferential trade agreement text and its rules of origin to determine eligibility for preferential tariff treatment. Proper documentation, such as a Certificate of Origin, is essential to claim these benefits.
What specific documentation is typically required for customs clearance of goods under HS 2833.22?
For customs clearance of products under HS 2833.22, standard import documentation is required, including a commercial invoice, packing list, and bill of lading or air waybill. Given the chemical nature of the product, additional documentation often includes a Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) and a Certificate of Analysis (CoA) to confirm the chemical composition and purity. If claiming preferential duty rates under a Free Trade Agreement, a valid Certificate of Origin (e.g., USMCA Certificate of Origin, EUR.1 movement certificate) is mandatory. Depending on the end-use and specific national regulations, permits or licenses from chemical regulatory bodies may also be required, although this is less common for basic industrial chemicals like aluminum sulfate unless it falls under specific controlled substance lists.
