HS 811251 Thallium

Quick Answer: Thallium imported under HS 811251 enters the UK at 0.00%, the EU at 1.50% ad valorem, and the US at a standard 4% ad valorem, with preferential rates available for certain trade partners. This Harmonized System code specifically covers unwrought thallium and thallium powder. Importers and customs brokers should be aware that while the UK offers duty-free entry, the EU imposes a modest tariff. The US rate can vary significantly based on the origin country, with many free trade agreements eliminating duties entirely, but a higher 25% rate applies to goods from unspecified origins. According to CustomTariffs data, careful origin verification is crucial for optimizing duty payments.

How to Classify This HS Code?

```html

What products does HS 811251 cover?

This subheading covers thallium and articles thereof, including unwrought thallium, powders, and waste and scrap of thallium. According to the World Customs Organization's Harmonized System Nomenclature, Heading 8112 specifically pertains to "Other base metals and articles thereof; cermets; articles thereof." Subheading 8112.51.00.00, as defined by the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database, encompasses pure thallium and its primary forms, excluding alloys unless thallium is the predominant metal by weight. This classification is based on the elemental composition and physical state of the material.

What falls outside HS 811251?

The following products are excluded from HS 811251: alloys where thallium is not the principal base metal by weight, compounds of thallium (such as thallium sulfate, which would typically be classified under Chapter 28), and finished articles manufactured from thallium that are specifically classified elsewhere in the HTS, such as certain electrical components or specialized scientific instruments. For instance, a thallium-doped scintillator crystal would likely fall under a different heading based on its function or material composition, rather than solely on the presence of thallium.

What are common classification mistakes for HS 811251?

A common error is misclassifying thallium compounds or alloys as unwrought thallium. General Rule of Interpretation (GRI) 1 states that classification shall be determined according to the terms of the headings and any relative Section or Chapter Notes. If a product is a compound, it should be classified as such, typically in Chapter 28, rather than under the base metal heading. Similarly, alloys where thallium is not the predominant metal by weight are not classified under 8112.51. Importers must carefully examine the chemical composition and the specific form of the imported material.

How should importers classify products under HS 811251?

The correct procedure for classifying products under HS 811251 involves a thorough examination of the imported material's composition and form. Importers and customs brokers must consult the official tariff schedule, such as the USITC HTS or the EU TARIC, and refer to the Explanatory Notes of the WCO. Key steps include verifying if the material is pure thallium or a waste/scrap thereof, and confirming that it is not a thallium compound or an alloy where thallium is not the principal base metal. Obtaining a Certificate of Analysis from the supplier is crucial for accurate classification.

How is the duty calculated for products under HS 811251?

A 100 kg shipment of unwrought thallium, declared at a customs value of $50,000 USD, would attract a US duty of $2,500. This is calculated using the Most Favored Nation (MFN) duty rate of 5% ad valorem, as published in the USITC Harmonized Tariff Schedule (HTS) for subheading 8112.51.00.00. The calculation is: 5% of $50,000 USD = $2,500 USD. This rate applies to goods imported from countries not benefiting from preferential trade agreements.

Which trade agreements reduce duties for HS 811251?

Several free trade agreements may reduce the applicable duty rate for HS 811251, including the United States-Mexico-Canada Agreement (USMCA), which can result in a duty rate of Free for qualifying goods originating from Canada or Mexico. For imports into the European Union, the Generalized System of Preferences (GSP) may offer reduced or Free duty rates for eligible developing countries, such as Vietnam. Documentation required typically includes a self-certified origin statement for USMCA or a GSP Form A for GSP beneficiaries, depending on the specific agreement and jurisdiction.

FAQ

What are the import duty rates for HS code 811251 (Thallium)?

The Most Favored Nation (MFN) duty rate for HS code 811251 (Thallium) is 2.5% ad valorem. Preferential duty rates may apply under various trade agreements. For example, under the US-Australia Free Trade Agreement, the rate is Free (0.00%). Importers should consult the specific tariff schedule of the importing country and any applicable trade agreements to determine the precise duty rate. Source: USITC Harmonized Tariff Schedule.

How is the import duty for Thallium (HS 811251) calculated?

The import duty for Thallium (HS 811251) is typically calculated on an ad valorem basis, meaning it is a percentage of the declared customs value of the goods. For example, if Thallium valued at $10,000 is imported and subject to the MFN rate of 2.5%, the duty would be calculated as: $10,000 (value) × 0.025 (duty rate) = $250. Importers must ensure accurate valuation and classification to ensure correct duty calculation.

What documentation is typically required for importing Thallium (HS 811251)?

Importing Thallium (HS 811251) requires specific documentation beyond standard customs entry forms. This typically includes a commercial invoice, packing list, and bill of lading or air waybill. Due to the hazardous nature of Thallium and its compounds, importers may also need to provide safety data sheets (SDS), certificates of origin, and potentially specific import permits or licenses issued by relevant government agencies (e.g., environmental protection or health authorities) depending on the importing country's regulations. It is crucial to verify these requirements with the destination country's customs authority.

Which trade agreements offer preferential duty rates for Thallium (HS 811251)?

Several trade agreements can provide preferential duty rates for Thallium (HS 811251). For instance, the USMCA (United States-Mexico-Canada Agreement) may offer reduced or zero duties for goods originating from Canada or Mexico. The US-Australia Free Trade Agreement provides a Free (0.00%) duty rate. Other agreements, such as those with South Korea (KORUS FTA), Chile, or Singapore, may also offer preferential treatment. Importers must ensure they meet the rules of origin criteria for the specific trade agreement to claim preferential rates. Consult the relevant tariff schedule for a comprehensive list of applicable agreements and their rates.

Are there specific classification criteria for Thallium (HS 811251) that importers should be aware of?

HS code 811251 specifically covers 'Thallium and articles thereof, including waste and scrap'. This means the code applies to unwrought thallium, powders, and semi-manufactured forms of thallium, as well as waste and scrap containing thallium. It is crucial to distinguish thallium from other base metals and their alloys. If the imported material is an alloy where thallium is a principal component by weight, it would fall under this heading. However, if thallium is present only as an impurity or in very small quantities in other base metals, it might be classified elsewhere. Always refer to the Explanatory Notes of the Harmonized System for detailed guidance on classification.
