HS 283319 Other
Quick Answer: HS code 2833.19, "Other," falls under Chapter 28, covering inorganic chemicals. Specifically, it encompasses sulfates of sodium not elsewhere specified within subheading 2833.1. This "Other" category typically captures less common or residual forms of sodium sulfates that don't fit into more specific subheadings. For importers and exporters, understanding this residual classification is crucial. Duty rates vary significantly: the UK applies a 4.00% ad valorem duty, while the EU imposes 5.50%. In contrast, the United States offers duty-free treatment for products classified under this code. Importers should verify the exact chemical composition and form to ensure correct classification and avoid potential penalties, especially given the varying duty implications across major markets.

How to Classify This HS Code?
What products does HS 283319 cover?
This subheading covers sulfates of disodium, specifically those not anhydrous. Heading 2833 encompasses sulfates; alums; peroxosulfates (persulfates); thiosulfates. Subheading 2833.19, designated as "Other," is the residual category for disodium sulfates that are not anhydrous, meaning they contain water of crystallization. This includes various hydrated forms of sodium sulfate, such as sodium sulfate decahydrate (Glauber's salt), which is a common form of this chemical. The WCO Harmonized System Explanatory Notes for Heading 2833 confirm the inclusion of various sulfates, and the USITC Harmonized Tariff Schedule (HTS) and EU TARIC system both delineate 2833.19 for these specific non-anhydrous disodium sulfates, distinguishing them from the anhydrous form classified under 2833.11.
What falls outside HS 283319?
The following products are excluded from HS 283319: anhydrous disodium sulfate, which is specifically classified under HS 2833.11. This distinction is crucial as it separates the water-free form from the hydrated forms. Additionally, other sulfates, such as those of magnesium (e.g., magnesium sulfate, Epsom salts), would be classified under 2833.29, or sulfates of other metals like copper sulfate (2833.25). Complex sulfates or double sulfates, unless specifically provided for elsewhere, would also fall outside this subheading, typically being classified under other specific subheadings within 2833 or even other chapters if they form part of a mixture or preparation with different primary characteristics. For instance, a mixture containing sodium sulfate but primarily functioning as a detergent would be classified in Chapter 34.
What are common classification mistakes for HS 283319?
A common error is misclassifying anhydrous disodium sulfate under 2833.19 instead of its correct subheading, 2833.11. Importers sometimes overlook the "anhydrous" distinction, leading to incorrect duty rates and potential compliance issues. Another frequent mistake involves classifying mixtures or preparations containing disodium sulfate under 2833.19 when the essential character of the product is imparted by another component or function, as per General Interpretative Rule (GRI) 3(b). For example, a cleaning product containing sodium sulfate as an inert filler, but whose primary function is cleaning, should be classified in Chapter 34. Furthermore, confusion can arise with other hydrated salts, leading to misclassification if the chemical identity as disodium sulfate is not accurately confirmed through laboratory analysis or supplier documentation.
How should importers classify products under HS 283319?
The correct procedure for classifying products under HS 283319 involves several critical steps. First, importers and customs brokers must precisely identify the chemical composition of the product, confirming it is indeed disodium sulfate and, crucially, that it is in a hydrated (non-anhydrous) form. This often requires reviewing Certificates of Analysis (CoAs) or Safety Data Sheets (SDS) from the manufacturer. Second, consult the WCO Harmonized System Explanatory Notes for Heading 2833 to understand the scope and exclusions. Third, cross-reference with the specific national tariff schedule, such as the USITC HTS or EU TARIC, to confirm the subheading 2833.19 for "Other" disodium sulfates (i.e., non-anhydrous). If there is any doubt regarding the anhydrous status, laboratory testing may be necessary. Always apply GRI 1 first, then subsequent GRIs if the product is a mixture or composite good, ensuring the classification accurately reflects the product's chemical identity and form.

FAQ
What is the import duty rate for HS 2833.19 in key markets, and are there preferential rates available?
The Most Favored Nation (MFN) duty rate for HS 2833.19 ('Other' sulfates) varies by importing country. For example, the United States (under the Harmonized Tariff Schedule of the United States, HTSUS) generally applies a 'Free' rate for MFN countries. The European Union (EU TARIC) may also apply a 'Free' rate for MFN. However, specific preferential rates may apply under various free trade agreements (FTAs). For instance, goods originating from countries with an FTA with the importing nation (e.g., USMCA for the U.S., or GSP for certain developing countries) could be eligible for a 'Free' rate, provided all rules of origin requirements are met. Importers should consult the specific tariff schedule of the importing country (e.g., USITC HTSUS, EU TARIC, UK Trade Tariff) and applicable trade agreement rules for the definitive rate.
What are the key classification criteria for products under HS 2833.19, and how does it differ from other subheadings within 2833?
HS 2833 covers 'Sulfates; alums; peroxosulfates (persulfates)'. Subheading 2833.11 specifically covers 'Sodium sulfates', and 2833.19 is the residual 'Other' category for sulfates. Products are classified under 2833.19 if they are sulfates (salts of sulfuric acid) but are not sodium sulfates (2833.11) or other specifically enumerated sulfates at a more granular level within national tariff schedules. The key criterion is the chemical identity as a sulfate, excluding sodium sulfates. For example, magnesium sulfate, potassium sulfate, or ammonium sulfate would typically fall under 2833.19 if not specified elsewhere. Importers must ensure the chemical name and composition precisely match the 'Other' sulfates description, adhering to the General Rules of Interpretation (GRIs), especially GRI 1 and GRI 6.
What documentation is typically required for importing goods classified under HS 2833.19?
Standard import documentation includes a commercial invoice, packing list, and bill of lading or air waybill. For chemical products like those in HS 2833.19, additional documentation is often crucial. This may include a Certificate of Analysis (CoA) or a Safety Data Sheet (SDS) to verify the chemical composition, purity, and safety characteristics, which can be vital for classification verification and compliance with chemical regulations. If claiming preferential duty rates under a free trade agreement (e.g., USMCA, GSP), a Certificate of Origin or a valid origin declaration is mandatory to substantiate the claim. Customs authorities may request these documents to confirm the classification and ensure compliance with all applicable import regulations.
Are there any specific trade agreements that offer preferential duty treatment for products under HS 2833.19 when imported into the United States?
Yes, products classified under HS 2833.19 imported into the United States may be eligible for preferential duty treatment under several trade agreements, often resulting in a 'Free' duty rate. Notable agreements include the United States-Mexico-Canada Agreement (USMCA), which provides duty-free access for originating goods from Mexico and Canada. Other agreements such as those with Australia, Chile, Colombia, Korea, Panama, Peru, and Singapore also offer preferential treatment. Additionally, certain developing countries may qualify for duty-free entry under the Generalized System of Preferences (GSP) program, although GSP eligibility can change. To claim preferential rates, goods must meet the specific rules of origin outlined in the respective agreement, and proper documentation, such as a Certificate of Origin, must be provided to U.S. Customs and Border Protection (CBP).
