This order cancels a previous tax exemption on importing specific mining equipment parts. What it does: Removes the concession (TC 0819450) that allowed businesses to import agitator blades and shafts (used in leaching plants for mineral processing) without paying full customs duty. Who is affected: Companies importing these parts under customs code 8479.90.00. What changes: From 27 July 2011, importers must pay standard tariffs on these items instead of receiving the earlier discount. Why it matters: This increases costs for mining and chemical processing operations that rely on this specific equipment.
