Ground natural calcium carbonate from the Oggaz plant (Sig, Mascara), commissioned in 2023 with a 100,000 t/year capacity on roughly 49 Mt of limestone reserves. Milled coarse to micronized per application for paper, paints, plastics, rubber and animal feed. Note on tariffs: uncoated natural GCC classifies under HS 2509, 2517.41 or 2530.90 depending on the source rock — we confirm the line per destination with the shipping documents.
