HS 284329 Other

Quick Answer: HS code 284329, "Other," falls under Chapter 28 for inorganic chemicals and covers various compounds of precious metals not elsewhere specified, excluding colloidal precious metals and amalgams. This residual category captures a diverse range of chemical preparations containing gold, silver, platinum, palladium, rhodium, iridium, or osmium, often used in catalysis, electronics, and specialized industrial applications. Duty rates vary significantly: the UK and EU generally apply a 0.00% ad valorem duty. In contrast, the US imposes a 3.7% ad valorem duty for most favored nation (MFN) imports, but can be as high as 25% for certain countries (e.g., China under Section 301 tariffs). Many US free trade agreements (FTAs) offer duty-free entry (e.g., for goods from Australia, Canada, Mexico, South Korea, etc.). Importers must verify the specific country of origin and applicable trade agreements to determine the correct duty rate. Accurate classification is crucial to avoid penalties and optimize customs duties.

How to Classify This HS Code?

What products does HS 284329 cover?

This subheading covers other compounds of silver, specifically those not elsewhere specified or included within subheading 2843.21, which is reserved for silver proteinates. Heading 2843 itself encompasses colloidal precious metals; inorganic or organic compounds of precious metals, whether or not chemically defined; and amalgams of precious metals. Therefore, 2843.29 serves as a residual category for various silver compounds, excluding colloidal silver and silver amalgams, which are classified under 2843.10 and 2843.90 respectively, and also excluding silver proteinates. Examples include silver nitrate, silver chloride, silver bromide, and silver iodide, provided they are not in colloidal form or specifically covered by other more precise headings or subheadings within Chapter 28, as per the WCO Harmonized System Explanatory Notes and official USITC and EU TARIC definitions.

What falls outside HS 284329?

The following products are excluded from HS 284329: colloidal silver, which is specifically classified under HS 2843.10.00; silver proteinates, which have their own dedicated subheading at HS 2843.21.00; and amalgams of precious metals, including silver amalgams, which fall under HS 2843.90.00. Additionally, articles made from silver compounds, such as photographic plates, film, or paper sensitized with silver halides (e.g., Chapter 37), or medicaments containing silver compounds (e.g., Chapter 30), are excluded. These are considered finished articles or preparations and are classified according to their function and composition in other chapters of the Harmonized System, rather than as simple chemical compounds of silver.

What are common classification mistakes for HS 284329?

A common error is misclassifying silver compounds that are actually in colloidal form under 2843.29 instead of the more specific 2843.10.00 for colloidal precious metals. Another frequent mistake involves classifying silver proteinates, which are explicitly covered by 2843.21.00, within this "other" residual subheading. Importers sometimes overlook the specific provisions for medicaments or photographic preparations containing silver compounds, incorrectly classifying them as raw chemical compounds under 2843.29 rather than their appropriate functional headings in Chapter 30 or 37, respectively. Adherence to General Interpretative Rule (GRI) 1, which prioritizes heading and subheading texts, and GRI 6, which applies GRIs mutatis mutandis at the subheading level, is crucial to avoid these errors.

How should importers classify products under HS 284329?

The correct procedure for classifying products under HS 284329 requires a thorough review of the product's chemical composition and form. Importers and customs brokers must first determine if the silver compound is colloidal (2843.10.00), a silver proteinate (2843.21.00), or an amalgam (2843.90.00). If none of these specific descriptions apply, and the product is an inorganic or organic compound of silver, not elsewhere specified, then 2843.29 is the appropriate classification. It is essential to consult the WCO Explanatory Notes for Heading 2843 and Chapter 28 to confirm that the product is not a preparation or article classified elsewhere in the HS. Obtaining a chemical analysis or manufacturer's declaration detailing the exact chemical nature and purity of the silver compound is highly recommended to ensure accurate classification and compliance with customs regulations.

FAQ

What is the Most Favored Nation (MFN) import duty rate for products classified under HS 2843.29 in the United States?

For products classified under Harmonized System (HS) subheading 2843.29, which covers 'Other' compounds of inorganic or organic precious metal compounds, the Most Favored Nation (MFN) import duty rate into the United States is 3.7% ad valorem. This rate applies to goods from countries that do not have a specific trade agreement or special program with the U.S. that would grant a lower or duty-free rate. Importers should verify the current rate via the U.S. International Trade Commission (USITC) Harmonized Tariff Schedule (HTS) for the most up-to-date information.

Are there any preferential duty rates or free trade agreements (FTAs) that offer duty-free entry for goods under HS 2843.29 into the United States?

Yes, numerous Free Trade Agreements (FTAs) and special trade programs allow for duty-free entry for products classified under HS 2843.29 into the United States, provided the goods meet the respective rules of origin. Countries eligible for duty-free treatment under various agreements include Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Dominican Republic (D.R.-CAFTA), El Salvador (E-CAFTA), Israel (IL), Jordan (JO), Korea (KR), Morocco (MA), Oman (OM), Panama (PA), Peru (PE), Singapore (SG), and others. Importers must ensure they have the necessary documentation, such as a Certificate of Origin, to claim preferential tariff treatment. Consult the specific FTA text and the USITC HTS General Notes for detailed rules of origin and documentation requirements.

What are the key classification criteria for determining if a product falls under HS 2843.29 'Other'?

HS 2843.29 is a residual subheading under HS 2843, which covers 'Colloidal precious metals; inorganic or organic compounds of precious metals, whether or not chemically defined; amalgams of precious metals.' Classification under 2843.29 'Other' means the product is an inorganic or organic compound of a precious metal (e.g., silver, gold, platinum, palladium, rhodium, iridium, osmium, ruthenium) that is not specifically provided for in HS 2843.10 (Colloidal precious metals) or 2843.21 (Silver compounds). Key criteria include the chemical composition, the specific precious metal involved, and whether it is chemically defined. Importers should refer to the Explanatory Notes to Chapter 28 of the Harmonized System for detailed guidance on the scope and interpretation of these headings.

What specific documentation is typically required by U.S. Customs and Border Protection (CBP) for importing goods under HS 2843.29?

For goods classified under HS 2843.29, standard import documentation is required, including a commercial invoice, packing list, and bill of lading or air waybill. If claiming preferential duty rates under a Free Trade Agreement, a valid Certificate of Origin or equivalent declaration is mandatory. Due to the nature of precious metal compounds, additional documentation such as a Safety Data Sheet (SDS) may be requested to verify the chemical composition and ensure compliance with other regulatory agencies (e.g., EPA, FDA) if applicable. Importers should also be prepared to provide detailed product specifications or chemical analyses if requested by CBP to support the classification.

Are there any specific import restrictions or special requirements for precious metal compounds under HS 2843.29?

While HS 2843.29 itself does not typically carry unique import restrictions beyond standard customs procedures, importers should be aware of potential regulations from other U.S. government agencies. Depending on the specific precious metal compound and its intended use, it may be subject to controls by the Environmental Protection Agency (EPA) under the Toxic Substances Control Act (TSCA), or potentially the Food and Drug Administration (FDA) if intended for certain applications. Additionally, due to the value of precious metals, importers should ensure robust security measures during transit and be aware of any reporting requirements for high-value shipments. It is crucial for importers to verify all applicable federal regulations based on the specific chemical identity and end-use of the imported compound.
