HS 284130 Sodium dichromate
Quick Answer: HS code 284130 specifically covers Sodium Dichromate, a chemical compound primarily used in the production of chromium compounds, pigments, and in leather tanning, wood preservation, and corrosion inhibition. Importers and customs brokers should note the varying Most Favored Nation (MFN) duty rates across major jurisdictions. For instance, the UK applies a 4.00% ad valorem duty, while the EU TARIC system shows a 5.50% ad valorem rate. In the United States, the MFN duty rate is 8.5% ad valorem, though significant preferential duty treatment (e.g., Free) is available under various trade agreements and preference programs (e.g., A*, AU, BH, CL, CO, D, E, IL, JO, KR, MA, OM, P, PA, PE, S, SG). Verifying origin and eligibility for these programs is crucial for duty optimization.

How to Classify This HS Code?
What products does HS 284130 cover?
This subheading covers sodium dichromate, which is a chemical compound with the formula Na₂Cr₂O₇. It is an inorganic chemical classified under Heading 2841, which encompasses chromates, dichromates, and peroxochromates; aluminates; chromates and dichromates of sodium or potassium. Specifically, 2841.30.00 is dedicated to "Sodium dichromate" as per the Harmonized System Nomenclature published by the World Customs Organization (WCO) and reflected in national tariffs such as the United States International Trade Commission (USITC) Harmonized Tariff Schedule (HTSUS) and the European Union's TARIC database. This includes both anhydrous and dihydrate forms of sodium dichromate, which are widely used in various industrial applications.
What falls outside HS 284130?
The following products are excluded from HS 284130: other chromates and dichromates, such as potassium dichromate (classified under 2841.50.00), and chromates of zinc or lead (classified under 2841.60.00). Additionally, chromium oxides and hydroxides, such as chromium trioxide (chromic acid), are classified under 2819.10.00, not within Heading 2841. Preparations containing sodium dichromate but formulated for specific uses, where the sodium dichromate is not the sole or principal constituent and the preparation takes on the character of a different product, would also be excluded and classified according to their specific function or composition, potentially under Chapter 38 or other relevant chapters.
What are common classification mistakes for HS 284130?
A common error is misclassifying other dichromates, particularly potassium dichromate, as sodium dichromate due to their similar chemical properties and uses. Importers must carefully verify the specific cation (sodium vs. potassium) to ensure correct classification, as potassium dichromate falls under 2841.50.00. Another mistake involves classifying mixtures or preparations containing sodium dichromate under 2841.30.00 when the product's essential character is derived from other components or its intended use. General Interpretative Rule (GRI) 3(b) would apply in such cases, directing classification by the component giving the mixture its essential character, or by GRI 3(c) if that is not determinable. Always ensure the product is indeed pure or substantially pure sodium dichromate.
How should importers classify products under HS 284130?
The correct procedure for classifying products under HS 284130 involves first confirming the chemical identity of the product as sodium dichromate (Na₂Cr₂O₇), whether anhydrous or dihydrate. 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, CAS number (e.g., 10588-01-9 for anhydrous, 7789-12-0 for dihydrate), and purity. This documentation is crucial for substantiating the classification. Next, verify that the product is not a mixture or preparation where sodium dichromate is merely an ingredient. Finally, cross-reference with official tariff schedules like the HTSUS or TARIC to ensure consistency and check for any specific national notes or rulings that might impact classification, applying GRI 1 for primary classification by heading and subheading text.

FAQ
What is the standard Most Favored Nation (MFN) import duty rate for HS code 2841.30 (Sodium dichromate) in the United States?
For imports into the United States, the general Most Favored Nation (MFN) duty rate for Harmonized System (HS) subheading 2841.30.00.00, covering Sodium dichromate, is 4.0% ad valorem. This rate applies to goods from countries without specific trade agreements or preferential programs with the U.S. Always refer to the latest USITC Harmonized Tariff Schedule of the United States (HTSUS) for the most current and authoritative information.
Are there any preferential duty rates available for Sodium dichromate (HS 2841.30) under U.S. Free Trade Agreements or special programs?
Yes, Sodium dichromate (HS 2841.30) may be eligible for preferential duty treatment under various U.S. Free Trade Agreements (FTAs) and special programs, potentially resulting in a 'Free' duty rate. For example, goods originating from countries such as 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 if all rules of origin requirements are met. Importers should consult the specific FTA text and the HTSUS General Notes to determine eligibility and required documentation, such as a Certificate of Origin.
What are the key classification criteria for Sodium dichromate under HS 2841.30?
HS code 2841.30 specifically covers 'Dichromates; chromates and peroxochromates.' Sodium dichromate, being a dichromate, falls directly under this subheading. The classification is based on its chemical identity and composition. Importers should ensure that the product being declared is indeed sodium dichromate (Na2Cr2O7) and not another chromium compound, as misclassification could lead to penalties. Reference to Chapter 28 of the Harmonized System Explanatory Notes (HSEN) provides further guidance on the classification of inorganic chemicals.
What documentation is typically required for importing Sodium dichromate (HS 2841.30)?
Standard import documentation for Sodium dichromate (HS 2841.30) includes a commercial invoice, packing list, bill of lading or air waybill, and potentially a Certificate of Analysis or Material Safety Data Sheet (MSDS) to confirm the chemical identity and safety information. If claiming preferential duty rates under a Free Trade Agreement, a valid Certificate of Origin (e.g., USMCA Certificate of Origin, Korea FTA Certificate of Origin) is mandatory. Additionally, due to its chemical nature, importers should be aware of any potential regulations from agencies like the Environmental Protection Agency (EPA) or other chemical control authorities that might require specific permits or declarations.
