HS 284590 Other

The Most Favored Nation (MFN) duty rates for HS 2845.90 ('Other' isotopes and their compounds, other than those of heading 28.44; mixtures and residues containing these products) vary significantly by importing country. For example, as of current tariffs:

• United States (USITC HTSUS): The General MFN duty rate is Free.
• European Union (TARIC): The MFN duty rate is 0.00% ad valorem.
• United Kingdom (UK Trade Tariff): The MFN duty rate is 0.00% ad valorem.
• Canada (Customs Tariff): The MFN duty rate is 0.00% ad valorem.
• Japan (Customs Tariff): The MFN duty rate is 0.00% ad valorem.

However, it is crucial for importers to verify the specific duty rate applicable to their country of importation and origin, as preferential trade agreements or specific national duties may apply. Some countries may have higher MFN rates, such as a hypothetical 5.50% ad valorem or even 25% for certain non-MFN origins or specific product types within this 'Other' category, though this is less common for isotopes under MFN.

HS 2845.90 is the residual subheading for 'Other' isotopes and their compounds, excluding those of heading 28.44 (radioactive chemical elements and radioactive isotopes). Classification under 2845.90 is appropriate for non-radioactive isotopes and their compounds, or mixtures and residues containing these products, that are not specifically provided for elsewhere.

Key Classification Criteria:

1. Non-Radioactive Nature: The primary distinction from 28.44 is the absence of radioactivity or the classification as non-radioactive isotopes.
2. Isotopic Compounds: The product must consist of or contain isotopes or their compounds.
3. 'Other' Category: It serves as a basket provision for items not more specifically described in other subheadings under 28.45 (e.g., 2845.10 for heavy water (deuterium oxide)).

Common Misclassification Risks:

• Confusion with Radioactive Isotopes (28.44): Importers must accurately determine if the isotopes are radioactive, as this would shift classification to 28.44, which often has different regulatory and duty implications.
• Specific Compounds: Misclassifying a specific isotopic compound that might have its own dedicated HS code if the isotopic nature is not the primary characteristic, or if it's explicitly mentioned elsewhere.
• Mixtures and Residues: Accurately identifying the principal constituent of mixtures or residues to ensure correct classification, especially if they contain both isotopic and non-isotopic materials.

Yes, preferential duty rates under various Free Trade Agreements (FTAs) or Generalized System of Preferences (GSP) schemes can significantly impact imports under HS 2845.90, often resulting in 0.00% ad valorem or 'Free' duty. Given that many major economies already apply a 0.00% or Free MFN rate to this specific HS code, the primary benefit of FTAs for 2845.90 often lies in solidifying this free entry and simplifying customs procedures.

Examples of FTAs that may offer preferential treatment:

• USMCA (United States-Mexico-Canada Agreement): Goods originating in Mexico or Canada imported into the US (and vice-versa) are typically duty-free under USMCA.
• EU FTAs (e.g., EU-Japan EPA, EU-South Korea FTA): Goods originating from partner countries often benefit from 0.00% duty rates upon meeting rules of origin.
• UK FTAs (e.g., UK-EU Trade and Cooperation Agreement, UK-Japan CEPA): Similar to EU agreements, goods originating from partner countries can enter duty-free.
• ASEAN FTAs: Various agreements within the ASEAN bloc and with external partners (e.g., RCEP) can provide preferential rates.

Actionable Guidance: Importers should always verify the specific rules of origin for their goods under the relevant FTA and ensure they possess the necessary documentation (e.g., certificate of origin) to claim preferential treatment. Even if the MFN rate is already zero, claiming FTA benefits can be important for compliance and future tariff changes.

While HS 2845.90 covers non-radioactive isotopes, the nature of these products often necessitates specific documentation beyond standard customs requirements. Importers should prepare the following:

1. Commercial Invoice: Standard document detailing the transaction, value, and description of goods.
2. Packing List: Itemizing contents and packaging details.
3. Bill of Lading or Air Waybill: Transportation document.
4. Certificate of Origin: Essential for claiming preferential duty rates under FTAs. Even with a 0.00% MFN rate, this can be crucial for compliance.
5. Technical Data Sheet/Certificate of Analysis (CoA): Given the specialized nature of isotopes, a CoA or detailed technical data sheet is often critical. This document should clearly state:
   • The specific isotope(s) and their compounds.
   • Purity levels.
   • Confirmation of non-radioactive status (if applicable, to distinguish from 28.44).
   • Chemical formula and CAS number.
6. Safety Data Sheet (SDS): Required for hazardous materials, even if non-radioactive. This provides crucial information for handling, storage, and emergency procedures.
7. Import Licenses/Permits: Depending on the specific isotope and its end-use, certain countries may require import licenses or permits from regulatory bodies (e.g., for dual-use goods, or specific chemical precursors), even if not radioactive. Importers should check national regulations thoroughly.

Actionable Guidance: Importers should proactively communicate with their supplier to obtain all necessary technical documentation and consult with a customs broker or regulatory specialist to confirm any country-specific import license requirements prior to shipment.
