HS 284150 Other chromates and dichromates; peroxochromates
Quick Answer: HS code 284150 encompasses various chromates, dichromates, and peroxochromates, which are inorganic chemical compounds primarily used in pigments, corrosion inhibitors, and chemical synthesis. For importers and customs brokers, understanding the specific sub-classification is crucial due to varying duty rates. In the UK, most products under this heading face a 4.00% ad valorem duty. The EU applies a general 5.50% ad valorem rate. The US tariff schedule shows more significant variation, with rates ranging from 3.1% to 25% ad valorem, alongside numerous preferential duty programs (e.g., A*, AU, CL, KR, SG) offering duty-free treatment for eligible goods. Importers should verify the exact product and country of origin to leverage potential duty savings.

How to Classify This HS Code?
What products does HS 284150 cover?
This subheading covers "Other chromates and dichromates; peroxochromates" as defined by the Harmonized System Nomenclature, specifically within Heading 2841, which encompasses salts of oxometallic or peroxometallic acids. This includes various inorganic chemical compounds where chromium is present in an anionic form, such as potassium chromate (K2CrO4), sodium dichromate (Na2Cr2O7), and ammonium dichromate ((NH4)2Cr2O7), provided they are not specifically covered by other more specific subheadings. The scope aligns with the official interpretations found in the USITC Harmonized Tariff Schedule of the United States (HTSUS) and the EU TARIC system, which both apply the WCO's Explanatory Notes for Chapter 28, ensuring consistent global classification.
What falls outside HS 284150?
The following products are excluded from HS 284150: zinc chromate (classified under 2841.30.00), lead chromates (classified under 2841.60.00), and chromates of magnesium, calcium, strontium, or barium (classified under 2841.70.00). Additionally, certain prepared pigments containing chromates, such as chrome yellows or chrome greens, are classified in Chapter 32 (e.g., 3206.20). Chromium oxides and hydroxides, which are not salts of chromic or dichromic acid, are classified under Heading 2819. Products containing chromium in a metallic or alloy form are also excluded, falling instead under Chapter 72 or 81, depending on the specific metal and form.
What are common classification mistakes for HS 284150?
A common error is misclassifying specific chromates that have their own dedicated subheadings within 2841, such as zinc chromate (2841.30.00) or lead chromates (2841.60.00), into the residual "other" category of 2841.50. This often occurs when importers overlook the specific provisions of the Harmonized System at the 6-digit or 8-digit level, failing to apply General Rule of Interpretation (GRI) 1 which prioritizes specific descriptions over general ones. Another mistake involves classifying prepared pigments containing chromates, which are mixtures, under 2841.50 instead of Chapter 32, thereby misinterpreting the scope of "inorganic chemicals" versus "preparations."
How should importers classify products under HS 284150?
The correct procedure for classifying products under HS 284150 involves a systematic review of the product's chemical composition and form, starting with GRI 1. Importers and customs brokers must first confirm that the product is indeed a chromate, dichromate, or peroxochromate. Next, they must meticulously check if the specific chromate (e.g., zinc, lead, magnesium, calcium, strontium, or barium chromate) has a more specific subheading within Heading 2841. If no more specific subheading applies, and the product is not a prepared pigment or mixture, then 2841.50 is the appropriate classification. Consulting the WCO Explanatory Notes for Chapter 28 and obtaining a chemical analysis report can provide definitive evidence for accurate classification.

FAQ
What are the typical Most Favored Nation (MFN) import duty rates for products classified under HS 2841.50?
The Most Favored Nation (MFN) import duty rates for products under HS 2841.50 ('Other chromates and dichromates; peroxochromates') generally range. For example, the United States Harmonized Tariff Schedule (HTSUS) may list an MFN (General) duty rate of 3.1% ad valorem. Other jurisdictions, such as the European Union's TARIC, might apply a Common Customs Tariff (CCT) duty rate of 5.5% ad valorem. Importers should consult the specific tariff schedule of the importing country (e.g., USITC HTSUS, EU TARIC, UK Trade Tariff) for the precise and current MFN duty rate applicable at the time of importation.
Are there any preferential duty rates available for HS 2841.50 under specific trade agreements?
Yes, preferential duty rates, including duty-free treatment, are often available for HS 2841.50 under various free trade agreements (FTAs) or special programs, provided the goods meet the respective rules of origin. For instance, imports into the United States may be eligible for duty-free treatment under agreements such as the USMCA (Mexico, Canada), CAFTA-DR (Dominican Republic, Central American countries), and FTAs with 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). Importers must ensure they have the correct origin documentation, such as a certificate of origin, to claim these preferential rates.
What are the key classification criteria for products under HS 2841.50?
HS 2841.50 specifically covers 'Other chromates and dichromates; peroxochromates.' The primary classification criterion is the chemical identity of the substance. This heading includes salts of chromic acid (chromates) and dichromic acid (dichromates), as well as compounds containing the peroxochromate ion. Importers and customs brokers must ensure that the chemical name, CAS number, and chemical formula accurately reflect one of these specified compounds. It's crucial to differentiate these from other chromium compounds classified elsewhere in Chapter 28 (e.g., chromium oxides under 2819) or inorganic salts of metals in other headings. Laboratory analysis or manufacturer's specifications detailing the exact chemical composition are often necessary for accurate classification.
What specific documentation is typically required for importing goods under HS 2841.50?
In addition to standard import documentation such as a commercial invoice, packing list, and bill of lading/air waybill, importers of goods under HS 2841.50 may require specific chemical-related documentation. This often includes a Safety Data Sheet (SDS) or Material Safety Data Sheet (MSDS) to identify the exact chemical composition and any hazardous properties. A Certificate of Analysis (CoA) from the manufacturer can also be highly beneficial to confirm the purity and specific chemical identity, aiding in classification and compliance with any chemical control regulations. For preferential duty claims, a valid Certificate of Origin is mandatory.
