How to Classify This HS Code?
What products does HS 810590 cover?
This subheading covers "Other" cobalt and articles thereof, including waste and scrap, and powders, not elsewhere specified within heading 8105. According to the World Customs Organization (WCO) Harmonized System Nomenclature, heading 8105 specifically pertains to cobalt and articles thereof, including waste and scrap. Subheading 8105.90 acts as a residual category for cobalt-containing materials that do not fit into more specific subheadings, such as unwrought cobalt or cobalt powders. For instance, this could include certain semi-finished cobalt products or alloys not explicitly defined elsewhere.
What falls outside HS 810590?
The following products are excluded from HS 810590: unwrought cobalt, cobalt powders, and waste and scrap of cobalt that are specifically classified under other subheadings of heading 8105. Additionally, articles of cobalt that are further manufactured and fall under different HS chapters, such as tools (Chapter 82) or machinery (Chapter 84), are not classified here. For example, cobalt-alloyed cutting tools would be classified under Chapter 82, not heading 8105.
What are common classification mistakes for HS 810590?
A common error is misclassifying cobalt alloys or articles containing cobalt that should be classified based on their primary function or material composition under other headings. For instance, cobalt-based superalloys used in aerospace might be incorrectly placed here instead of under headings related to specific machinery components. General Interpretative Rule 1 (GIR 1) and Rule 3(b) of the Harmonized System are crucial for ensuring correct classification, emphasizing that classification is determined by the terms of the headings and any relative section or chapter notes.
How should importers classify products under HS 810590?
The correct procedure for classifying products under HS 810590 involves a thorough examination of the product's composition and form, referencing the official WCO HS Nomenclature and national tariff schedules like the USITC Harmonized Tariff Schedule (HTS) or the EU TARIC. Importers must determine if the product is indeed cobalt or an article thereof and confirm it is not specifically provided for in more precise subheadings within 8105. If the product meets these criteria, it can be classified under 8105.90. Consulting with a customs broker is advisable for complex cases.
How is the duty calculated for products under HS 810590?
A shipment of 500 kilograms of cobalt-based scrap, declared at a customs value of $10,000 USD, would attract a US duty of $500.00. This is calculated using the U.S. Most Favored Nation (MFN) duty rate of 5% ad valorem, applied to the declared customs value. The calculation is $10,000 USD (value) × 0.05 (duty rate) = $500.00 (duty amount). This rate is published in the USITC Harmonized Tariff Schedule (HTS) under subheading 8105.90.0000.
Which trade agreements reduce duties for HS 810590?
Several free trade agreements may reduce the applicable duty rate for HS 810590, including the United States-Mexico-Canada Agreement (USMCA), which can result in a duty rate of Free for originating goods from Canada and Mexico. The African Growth and Opportunity Act (AGOA) may also offer preferential rates for eligible countries. Documentation required to claim preference under USMCA typically involves a self-certified origin statement on the invoice. For AGOA, specific eligibility criteria and documentation are required by U.S. Customs and Border Protection.
