HS 283429 Other
Quick Answer: HS code 283429, "Other," encompasses a diverse range of inorganic nitrites and nitrates not specifically classified elsewhere within heading 2834. This includes various chemical compounds used in industries such as agriculture, pharmaceuticals, and manufacturing. For instance, it could cover specific metallic nitrates or nitrites beyond those explicitly listed in subheadings like 283421 (Potassium nitrate) or 283422 (Bismuth nitrate). Duty rates vary significantly by jurisdiction. The UK Trade Tariff shows rates such as 4.00% and 2.00% ad valorem. The EU TARIC indicates rates like 5.50%, 4.60%, and 3.00% ad valorem. The US Harmonized Tariff Schedule (HTS) presents a broad range, including 35%, 5.5%, and "Free" for goods originating from countries eligible for specific trade programs (e.g., A, AU, BH, CL, CO, D, E, IL, JO, KR, MA, OM, P, PA, PE, S, SG). Importers and customs brokers must verify the exact chemical composition and country of origin to determine the applicable duty rate and leverage potential preferential trade agreements.

How to Classify This HS Code?
What products does HS 283429 cover?
This subheading covers other nitrites and nitrates, specifically those not falling under subheading 283421, which is reserved for potassium nitrate. According to the Harmonized System Nomenclature Explanatory Notes (WCO), Heading 2834 encompasses nitrites and nitrates, as well as sulphonitrates and sulphoaminonitrates. Subheading 283429 therefore acts as a residual category for all nitrates other than potassium nitrate, including but not limited to sodium nitrate, calcium nitrate, ammonium nitrate, and various metallic nitrates, provided they are chemically defined compounds. This scope is consistent across the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC system, ensuring uniform application for these inorganic chemical compounds.
What falls outside HS 283429?
The following products are excluded from HS 283429: potassium nitrate, which is specifically classified under HS 28342100. Additionally, mixtures of nitrates, unless they form a chemically defined compound, are generally excluded and may fall under other headings, such as Heading 3102 for mineral or chemical fertilizers containing nitrogen, if they are put up as fertilizers. For example, ammonium nitrate in aqueous solution, if it meets the criteria for a fertilizer solution, would be classified in Chapter 31. Similarly, explosives containing nitrates are classified in Chapter 36, and certain organic nitrates are classified in Chapter 29. The key distinction is whether the product is a chemically defined inorganic nitrate compound, excluding potassium nitrate, or a preparation or mixture with a specific end-use.
What are common classification mistakes for HS 283429?
A common error is misclassifying mixtures containing nitrates, especially those intended for agricultural use, into HS 283429 when they should be classified in Chapter 31 as fertilizers. Importers often overlook the specific provisions for fertilizers, which take precedence due to their specific composition and intended use. Another mistake involves classifying potassium nitrate under this subheading instead of its dedicated subheading 283421. Furthermore, applying General Interpretative Rule (GRI) 1, which states that classification shall be determined according to the terms of the headings and any relative section or chapter notes, is crucial. Failure to correctly identify the chemical definition and purity of the nitrate, or its primary function if it's part of a preparation, can lead to incorrect classification and potential customs penalties.
How should importers classify products under HS 283429?
The correct procedure for classifying products under HS 283429 involves a meticulous review of the product's chemical composition and purity. Importers and customs brokers should first ascertain if the product is a chemically defined inorganic nitrate, excluding potassium nitrate. Obtain a detailed Certificate of Analysis (CoA) or Safety Data Sheet (SDS) from the manufacturer to confirm the exact chemical name and purity. Consult the WCO Harmonized System Explanatory Notes for Heading 2834 to understand the scope of nitrites and nitrates. If the product is a nitrate other than potassium nitrate and is a chemically defined compound, then HS 283429 is appropriate. Always verify against the latest USITC HTS or EU TARIC to ensure no specific national variations or binding rulings apply, and consider seeking a binding ruling for complex or ambiguous cases.

FAQ
What is the Most Favored Nation (MFN) import duty rate for products classified under HS 2834.29 in key markets, and what does 'Other' signify?
The MFN (Most Favored Nation) duty rates for HS 2834.29, which covers 'Other' nitrites and nitrates, vary significantly by importing country. For instance, the United States generally applies an MFN duty rate of 3.0% ad valorem. The European Union's TARIC database indicates an MFN duty rate of 5.5% ad valorem for many products under this subheading. The UK Global Tariff also lists a 5.5% ad valorem MFN rate. Canada applies a 4.0% ad valorem MFN rate. The term 'Other' within HS 2834.29 indicates that this subheading covers nitrites and nitrates that are not specifically enumerated in subheadings 2834.21 (Potassium nitrate) or 2834.22 (Barium nitrate), thereby serving as a residual category for other chemical compounds of this type. Importers should always verify the specific duty rate applicable to their destination country via official customs tariffs like the USITC Harmonized Tariff Schedule, EU TARIC, or the UK Trade Tariff.
Which preferential trade agreements offer duty-free or reduced rates for goods under HS 2834.29, and how can importers claim these benefits?
Many preferential trade agreements provide duty-free or reduced rates for products classified under HS 2834.29. For example, under the United States' various Free Trade Agreements (FTAs), 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) can often enter duty-free. Similarly, the EU has agreements that may grant preferential treatment. To claim these benefits, importers must ensure the goods meet the specific Rules of Origin (ROO) criteria outlined in the respective trade agreement. This typically involves providing a valid Certificate of Origin or an origin declaration from the exporter, confirming that the product qualifies as originating from a beneficiary country. Failure to provide proper documentation will result in the application of the MFN duty rate.
What are the key classification criteria for distinguishing products under HS 2834.29 from other chemical classifications?
The primary classification criteria for HS 2834.29 revolve around the chemical composition of the product. This subheading specifically covers 'Nitrites; nitrates; other' within Chapter 28, which pertains to inorganic chemicals. To be classified here, the product must be an inorganic nitrite or nitrate that is not specifically provided for in subheadings 2834.21 (Potassium nitrate) or 2834.22 (Barium nitrate). Importers and customs brokers must ensure the chemical name and CAS (Chemical Abstracts Service) number accurately reflect an 'other' nitrite or nitrate. For instance, sodium nitrite (CAS 7632-00-0) or calcium nitrate (CAS 10124-37-5) would typically fall under this subheading if not specifically enumerated elsewhere. It is crucial to consult the Harmonized System Explanatory Notes for Chapter 28 and Section VI to confirm the precise scope and exclusions for nitrites and nitrates.
What specific documentation is required for the import of chemicals under HS 2834.29, beyond standard customs declarations?
Beyond standard customs documentation such as the commercial invoice, packing list, and bill of lading/air waybill, the import of chemicals under HS 2834.29 often requires additional regulatory documentation. Depending on the specific chemical and its intended use, importers may need to provide a Safety Data Sheet (SDS) or Material Safety Data Sheet (MSDS) to comply with chemical safety regulations (e.g., OSHA in the US, REACH in the EU). For certain hazardous chemicals, permits or licenses from environmental protection agencies or chemical control authorities may be necessary. If claiming preferential duty rates, a valid Certificate of Origin or origin declaration is mandatory. Importers should also be aware of any specific labeling requirements for chemical substances in the destination country. It is highly recommended to consult with a licensed customs broker and the relevant national regulatory bodies prior to importation to ensure full compliance.
