HS 282510 Hydrazine and hydroxylamine and their inorganic salts
Quick Answer: HS code 282510 covers hydrazine, hydroxylamine, and their inorganic salts. These are critical chemical compounds used in various industrial applications, including pharmaceuticals, agrochemicals, water treatment, and as reducing agents. Importers and exporters should note the varying duty rates across major jurisdictions. For the UK, the Most Favoured Nation (MFN) duty rate is typically 4.00% ad valorem. The EU applies an MFN rate of 5.50% ad valorem. In the United States, the MFN duty rate is 3.7% ad valorem, with potential for duty-free entry under various Free Trade Agreements (e.g., A, AU, BH, CL, CO, D, E, IL, JO, KR, MA, OM, P, PA, PE, S, SG). Accurate classification is essential to leverage preferential trade agreements and ensure compliance.

How to Classify This HS Code?
What products does HS 282510 cover?
This subheading covers hydrazine and hydroxylamine, along with their inorganic salts, as specified by the Harmonized System Nomenclature (WCO HS Explanatory Notes, Chapter 28, Heading 2825). Hydrazine (N2H4) is a highly reactive inorganic compound often used as a foaming agent, polymerization catalyst, and in rocket fuel. Hydroxylamine (NH2OH) is another inorganic compound, typically encountered as an aqueous solution or as its salts, used in organic synthesis and as a reducing agent. Their inorganic salts include compounds like hydrazine sulfate, hydrazine hydrate, hydroxylamine hydrochloride, and hydroxylamine sulfate, provided they are inorganic in nature and meet the purity requirements for Chapter 28 chemicals.
What falls outside HS 282510?
The following products are excluded from HS 282510: organic derivatives of hydrazine or hydroxylamine, which are classified elsewhere, typically in Chapter 29 if they are defined organic compounds of known chemical structure. For instance, phenylhydrazine, an organic compound, would be classified under HS 2928.00. Additionally, mixtures containing hydrazine or hydroxylamine that are prepared as medicaments or diagnostic reagents fall under Chapter 30. Formulations specifically prepared as pesticides, disinfectants, or similar products, even if containing these chemicals, are generally classified under Chapter 38, depending on their primary function and composition, rather than as pure inorganic chemicals.
What are common classification mistakes for HS 282510?
A common error is misclassifying organic derivatives of hydrazine or hydroxylamine under HS 282510, rather than their correct Chapter 29 headings. Importers sometimes overlook the distinction between inorganic salts and organic compounds, leading to incorrect duty rates and potential compliance issues. For example, hydrazine hydrate, an inorganic compound, correctly falls here, but a complex organic hydrazine derivative would not. Another mistake involves classifying prepared formulations (e.g., a hydrazine-based pesticide) here instead of Chapter 38, violating General Interpretative Rule (GRI) 3(a) which prioritizes specific descriptions over general ones, or GRI 3(b) for mixtures. Always verify the chemical structure and primary function.
How should importers classify products under HS 282510?
The correct procedure for classifying products under HS 282510 involves first confirming the chemical identity as either hydrazine, hydroxylamine, or one of their inorganic salts. Importers and customs brokers should obtain a detailed Certificate of Analysis (CoA) or Safety Data Sheet (SDS) from the manufacturer, clearly stating the chemical name, CAS number, and purity. Verify that the product is not an organic derivative or a prepared formulation for a specific end-use (e.g., medicament, pesticide). Consult the WCO Harmonized System Explanatory Notes for Heading 2825 and cross-reference with the USITC Harmonized Tariff Schedule (HTS) or EU TARIC for specific national interpretations and duty rates. For the United States, the Most Favored Nation (MFN) duty rate for 2825.10.00.00 is 3.5% ad valorem, as per the USITC HTS. Ensure all documentation supports the inorganic nature and chemical purity for Chapter 28 classification.

FAQ
What are the typical Most Favored Nation (MFN) import duty rates for HS 2825.10 (Hydrazine and hydroxylamine and their inorganic salts) in major markets?
The MFN (Most Favored Nation) import duty rates for HS 2825.10 can vary significantly by importing country. For example, the United States generally applies a duty rate of 3.7% ad valorem under the Harmonized Tariff Schedule of the United States (HTSUS) for products from non-preferential countries. The European Union's TARIC database shows a common customs tariff duty rate of 5.50% ad valorem. The UK Global Tariff also lists a 5.50% ad valorem duty. Other countries may have rates such as 4.00% or even 25% for specific trade relationships. Importers should always consult the specific tariff schedule of the destination country for the most accurate and current MFN rate.
Are there any preferential duty rates available for HS 2825.10 under common Free Trade Agreements (FTAs) or special programs?
Yes, preferential duty rates, often 'Free' (0% ad valorem), are available for HS 2825.10 under various Free Trade Agreements (FTAs) and special trade programs, provided the goods meet the respective Rules of Origin. For instance, imports into the United States may be duty-free 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) under their respective FTAs. Similarly, the EU and UK also offer preferential rates under their extensive networks of agreements (e.g., GSP, specific FTAs). Importers should verify the origin of their goods and claim preference correctly on customs declarations to benefit from these reduced or zero duties.
What are the key classification criteria for distinguishing between hydrazine, hydroxylamine, and their inorganic salts under HS 2825.10?
HS 2825.10 specifically covers 'Hydrazine and hydroxylamine and their inorganic salts'. The primary classification criterion is the chemical identity of the substance. Hydrazine (N2H4) and hydroxylamine (NH2OH) are distinct inorganic chemical compounds. Their 'inorganic salts' refer to compounds formed when these bases react with inorganic acids, such as hydrazine sulfate or hydroxylamine hydrochloride. It is crucial to ensure that the product is indeed an inorganic salt and not an organic derivative or a mixture where the primary characteristic is not hydrazine or hydroxylamine or their inorganic salts. Purity levels and the presence of other components might also be relevant for classification, though generally, the chemical structure is paramount. WCO Explanatory Notes for Chapter 28 provide further guidance on the scope of inorganic chemicals.
What specific documentation is typically required by customs authorities for imports of HS 2825.10, especially concerning safety and chemical compliance?
Beyond standard import documentation (commercial invoice, packing list, bill of lading/air waybill), imports of HS 2825.10, being chemical substances, often require additional safety and chemical compliance documentation. This typically includes: 1. Safety Data Sheet (SDS): Essential for hazard communication, providing information on properties, hazards, and safe handling. 2. Certificate of Analysis (CoA): Verifies the chemical composition, purity, and specifications of the product. 3. Chemical Registration/Notification: Depending on the destination country, compliance with chemical control regulations (e.g., TSCA in the US, REACH in the EU, K-REACH in Korea) may necessitate pre-market notification or registration. Importers must confirm that the chemical is listed on relevant national inventories or that appropriate exemptions/registrations are in place. Failure to provide these documents can lead to delays, penalties, or refusal of entry.
