Nickel mattes
Nickel mattes, an intermediate product of nickel metallurgy
HSN 7501 10 00 (Nickel mattes) is not covered by a Bureau of Indian Standards Quality Control Order and carries no Partner Government Agency clearance requirement at the tariff-line level. Import follows the standard customs procedure: Importer-Exporter Code, bill of entry, commercial invoice, packing list. Other intermediate products of nickel metallurgy under the same heading — including nickel oxide sinters — may be classified on separate tariff lines within Chapter 75 and warrant independent classification review.
Nickel mattes are a smelter intermediate, and their precise metallurgical specification — sulphur content, nickel grade, moisture — determines the correct tariff line within the heading. Re-classification by customs to a more specific line, or to a refined nickel product line elsewhere in Chapter 75, triggers retrospective compliance and potential detention pending re-assessment of applicable duties. Confirm the product specification and intended downstream use against the customs tariff before relying on the absence of compliance at this tariff line.
