HS 283719 Other
Quick Answer: HS code 2837.19, "Other," encompasses cyanides and cyanide oxides of inorganic bases, excluding sodium cyanide (2837.11) and potassium cyanide (2837.19.10). This classification covers a range of industrial chemicals used in metallurgy, electroplating, and chemical synthesis. Importers should note varying duty rates: the UK Trade Tariff generally applies a 0.00% ad valorem duty, while the EU TARIC system typically levies a 5.50% ad valorem duty. For the United States, most products under this subheading are classified as "Free" of duty. Accurate classification is crucial due to the hazardous nature of these chemicals and the potential for regulatory scrutiny. Importers and customs brokers must verify specific product compositions against national tariff schedules to ensure compliance and avoid penalties.

How to Classify This HS Code?
What products does HS 283719 cover?
This subheading covers cyanides and cyanide oxides of inorganic bases, specifically those not elsewhere specified or included within subheading 2837.11 (sodium cyanide). According to the Harmonized System Nomenclature Explanatory Notes (WCO) and consistent with definitions found in the USITC Harmonized Tariff Schedule of the United States (HTSUS) and the EU TARIC, this includes a range of inorganic cyanides such as potassium cyanide, calcium cyanide, and zinc cyanide, provided they are not complex cyanides of subheading 2837.20. These are generally salts of hydrocyanic acid (HCN) with various metal cations, used in diverse industrial applications.
What falls outside HS 283719?
The following products are excluded from HS 283719: sodium cyanide, which is specifically classified under subheading 2837.11 due to its significant commercial importance and distinct chemical identity. Additionally, complex cyanides, such as ferrocyanides and ferricyanides (e.g., potassium ferrocyanide), are explicitly classified under subheading 2837.20, as they involve more intricate coordination chemistry. Organic cyanides, also known as nitriles, are entirely excluded from Heading 2837 and are typically found in Chapter 29, covering organic chemicals, demonstrating a clear distinction between inorganic and organic chemical compounds for classification purposes.
What are common classification mistakes for HS 283719?
A common error is misclassifying sodium cyanide under 2837.19 instead of its specific subheading 2837.11, which is a direct violation of General Rule of Interpretation (GRI) 1, requiring classification according to the terms of the headings and any relative section or chapter notes. Another frequent mistake involves incorrectly placing complex cyanides, such as potassium ferrocyanide, into 2837.19, when they clearly belong to 2837.20 as per the specific wording of the subheadings. Importers sometimes also confuse organic nitriles with inorganic cyanides, leading to erroneous classification in Chapter 28 instead of Chapter 29, necessitating careful chemical identification.
How should importers classify products under HS 283719?
The correct procedure for classifying products under HS 283719 involves a meticulous review of the chemical composition and specific identity of the cyanide salt. Importers and customs brokers must first confirm that the product is an inorganic cyanide and not sodium cyanide (which goes to 2837.11) or a complex cyanide (which goes to 2837.20). Verification of the cation (e.g., potassium, calcium, zinc) is crucial. Consulting the WCO Explanatory Notes for Heading 2837, along with official tariff schedules like the USITC HTSUS or EU TARIC, is essential to ensure accurate classification and compliance with GRI 1 and 6, thereby avoiding potential penalties or delays.

FAQ
What is the import duty rate for products classified under HS 2837.19 in key markets?
The Most Favored Nation (MFN) duty rates for HS 2837.19 'Other cyanides and cyanide-oxides' vary by importing country. For example, as per the USITC Harmonized Tariff Schedule (HTS) under subheading 2837.19.00.00, the General duty rate is 3.5% ad valorem. The EU TARIC database indicates a MFN duty rate of 5.5% ad valorem for goods under CN code 2837 19 00. The UK Global Tariff (UKGT) also lists a 5.5% ad valorem duty rate for HS 2837.19.00.00. Importers should always verify the current rates with the official tariff schedule of the destination country.
What are the primary classification criteria for products under HS 2837.19?
HS 2837.19 is a residual subheading under HS 2837, which covers 'Cyanides, cyanide oxides and complex cyanides.' Products fall into 2837.19 if they are cyanides or cyanide oxides that are not specifically enumerated in HS 2837.11 ('of sodium') or 2837.12 ('of other alkali metals'). Classification hinges on the chemical composition: the product must be a cyanide or cyanide oxide, and the cation must not be sodium or another alkali metal (e.g., potassium, lithium, rubidium, cesium). Importers should provide a detailed chemical analysis or safety data sheet (SDS) to customs authorities to substantiate the classification.
Are there any preferential duty rates available for HS 2837.19 under common trade agreements?
Yes, preferential duty rates may apply to HS 2837.19 depending on the country of origin and the trade agreements in force. For instance, under the US HTS, goods from countries eligible for Generalized System of Preferences (GSP) or certain free trade agreements (e.g., USMCA, CAFTA-DR) may qualify for a 'Free' duty rate. Similarly, the EU and UK offer preferential tariffs under various agreements like the Generalised Scheme of Preferences (GSP) or specific Free Trade Agreements (FTAs). To claim preferential treatment, importers must ensure the goods meet the specific Rules of Origin criteria of the applicable agreement and provide a valid Certificate of Origin or origin declaration.
What documentation is typically required for importing goods classified under HS 2837.19?
Given that HS 2837.19 covers cyanides, which are often hazardous chemicals, importers can expect stringent documentation requirements. Essential documents typically include a commercial invoice, packing list, bill of lading or air waybill, and a Certificate of Origin. Additionally, due to the nature of the goods, a Safety Data Sheet (SDS) is crucial for customs and regulatory compliance. Depending on the importing country's regulations, permits or licenses from environmental protection agencies or chemical control authorities may also be mandatory. Customs brokers should confirm all specific import requirements with the relevant national authorities prior to shipment.
