HS 280429 Other
Quick Answer: HS 2804.29, "Other," covers various rare gases not specifically classified elsewhere under HS 2804.2 (e.g., neon, argon, krypton, xenon). This includes less common noble gases or mixtures thereof. Importers should be aware of varying duty rates: the UK Trade Tariff shows rates from 0.00% to 4.00% ad valorem, while the EU TARIC ranges from 0.00% to 5.00% ad valorem. The US Harmonized Tariff Schedule (HTS) presents a broader range, from 3.7% to 25% ad valorem, with many products eligible for "Free" duty under various Free Trade Agreements (e.g., A, AU, CL, KR, SG). Accurate classification within this "Other" category is crucial to avoid misdeclarations and ensure correct duty assessment, especially given the significant rate differences and potential FTA benefits.

How to Classify This HS Code?
What products does HS 280429 cover?
This subheading covers rare gases other than argon, specifically neon, krypton, and xenon, in their unmixed, uncompressed, or compressed forms. According to the Harmonized System Explanatory Notes (HSEN) for Heading 2804, this includes these elements whether they are in gaseous or liquid state, provided they meet the purity requirements for chemical elements. The USITC Harmonized Tariff Schedule (HTS) and EU TARIC system both align with the WCO nomenclature, classifying these specific rare gases under this residual "Other" subheading when they are not argon, which has its own dedicated subheading (2804.21).
What falls outside HS 280429?
The following products are excluded from HS 280429: argon (classified under 2804.21), helium (classified under 2804.21), and mixtures of rare gases. For instance, a mixture of neon and argon would typically be classified under 2804.29.90 (for the US HTS) or 2804.29.90.00 (for EU TARIC) if the predominant rare gas is neon, but if it's a specific mixture for a particular use, it might fall under other headings, such as 3824 if it constitutes a prepared binder for foundry moulds or cores. Additionally, rare gases that are chemically combined with other elements to form compounds are excluded, as Heading 2804 is specifically for uncombined chemical elements.
What are common classification mistakes for HS 280429?
A common error is misclassifying mixtures of rare gases or rare gases combined with other elements. Importers sometimes incorrectly classify a mixture of, for example, neon and argon under 2804.29, when a specific mixture might be more appropriately classified elsewhere, depending on its composition and intended use, potentially under Chapter 38 as a prepared chemical product. Another mistake is failing to distinguish between pure rare gases and their compounds. General Interpretative Rule (GRI) 1 dictates that classification is determined according to the terms of the headings and any relative section or chapter notes, which clearly define Heading 2804 for uncombined elements, not their compounds.
How should importers classify products under HS 280429?
The correct procedure for classifying products under HS 280429 involves first confirming that the product is indeed a rare gas (neon, krypton, or xenon) and not argon or helium. Importers and customs brokers should obtain a certificate of analysis or a technical data sheet from the manufacturer to verify the chemical identity and purity of the gas. This documentation is crucial to demonstrate that the product is an uncombined chemical element and not a mixture or compound. Furthermore, they must ensure the product is not argon (2804.21) or helium (2804.21). Consulting the WCO HS Explanatory Notes for Heading 2804 and specific national tariff schedules (e.g., USITC HTS, EU TARIC) is essential to confirm the precise scope and any national specificities for "Other" rare gases.

FAQ
What is the Most Favored Nation (MFN) import duty rate for HS code 2804.29 and are there any common preferential rates?
The MFN (Most Favored Nation) import duty rate for HS code 2804.29, which covers 'Other' inert gases, varies significantly by importing country. For example, the MFN duty rate in the United States is 0.00% ad valorem, as per the Harmonized Tariff Schedule of the United States (HTSUS). In contrast, some countries may apply MFN rates such as 4.00% or 5.00% ad valorem. Many preferential trade agreements offer duty-free access (0.00%) for goods classified under 2804.29. Importers should check specific agreements such as the USMCA (United States-Mexico-Canada Agreement), various Free Trade Agreements (FTAs) with countries like Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Korea (KR), Panama (PA), Peru (PE), and Singapore (SG), or Generalized System of Preferences (GSP) programs where applicable. Always verify the specific country of origin and destination tariff schedule.
What are the key classification criteria for inert gases under HS 2804.29, particularly distinguishing it from other subheadings?
HS code 2804.29 specifically covers 'Other' inert gases, meaning those not classified under more specific subheadings within 2804. This heading (2804) covers 'Hydrogen, rare gases and other non-metals.' Subheading 2804.21 is for Argon, 2804.22 for Krypton, 2804.23 for Neon, 2804.24 for Xenon, and 2804.25 for Helium. Therefore, 2804.29 is the residual subheading for any other inert gases not explicitly named in 2804.21 through 2804.25, such as Radon. Classification hinges on the specific chemical identity of the inert gas. Importers must ensure the product's chemical name and purity align with the 'Other' designation and are not one of the specifically enumerated rare gases.
What documentation is typically required for importing inert gases under HS 2804.29 to claim preferential duty rates?
To claim preferential duty rates for inert gases under HS 2804.29, importers typically need to provide a Certificate of Origin (COO) or an origin declaration, depending on the specific trade agreement. For example, under the USMCA, a certification of origin may be required. For other FTAs, a specific form (e.g., EUR.1 for certain EU agreements) or a declaration on the commercial invoice might be acceptable. Essential supporting documents include the commercial invoice, packing list, and bill of lading/air waybill. Customs authorities may also request a Safety Data Sheet (SDS) or a Certificate of Analysis (CoA) to verify the chemical identity and purity of the inert gas, ensuring it correctly falls under 2804.29 and meets any product-specific regulations.
Are there any specific import restrictions or special requirements for inert gases classified under HS 2804.29?
While inert gases under HS 2804.29 are generally not subject to extensive import restrictions compared to hazardous chemicals, importers should be aware of potential regulations related to their safe handling, transport, and storage. These gases are typically shipped in pressurized cylinders or tanks, which must comply with international and national safety standards (e.g., DOT regulations in the US, ADR in Europe). Furthermore, some countries may have specific environmental or health agency requirements for industrial gases. Although 2804.29 itself doesn't typically trigger specific licensing, it's crucial to confirm that the specific inert gas (e.g., Radon, if applicable) does not fall under any national security, dual-use, or environmental control lists that would necessitate special permits or reporting.
