Import Bauxite — Buy in wholesale FOB from Supplier in France

Guimarts offers metallurgical-grade bauxite with Al2O3 content ranging from 40% to 55%, sourced from Guinea for delivery via France. The material is positioned as a competitive feedstock for alumina refineries and primary aluminium smelters, with monthly quantities fixed at 185,000 MT over a ten-month supply window. The pricing is set at $45 FOB net seller, requiring a Letter of Intent (LOI) for transaction processing. This grade sits within the standard range for Bayer-process feedstock, where higher Al2O3 and lower silica content improve refining economics. The supplier explicitly notes that monthly deliveries depend on the start and duration of the rainy season in West Africa, a genuine logistical constraint for Guinean bauxite exports.

The ore is described as natural and grainy, consistent with typical Guinean bauxite deposits found in the Boke and Fria basins. Metallurgical-grade bauxite for alumina production typically requires Al2O3 above 45% and reactive silica below 5% for efficient digestion in caustic soda. Guimarts does not publish detailed impurity profiles, so buyers should request full chemical assay including SiO2, Fe2O3, TiO2 and organic carbon content. The 40-55% Al2O3 range suggests some batch variability, common in bulk Guinean ore where blending occurs at loading ports. Typical moisture content for this origin runs 17-20%, which affects net dry tonnage calculations and vessel loading rates.

Primary buyers include alumina refineries, integrated aluminium producers and commodity traders with smelter offtake agreements. The 185,000 MT/month volume suits large refineries consuming 2-3 million tonnes annually. Buyers should confirm whether Guimarts provides independent sampling and analysis at load port, standard for FOB Guinean contracts. The LOI requirement indicates the supplier deals through formal channels rather than spot tenders. FOB terms place maritime freight, insurance and discharge risk on the buyer, so vessel chartering capability is essential.

Guimarts is headquartered at 49 Cours Pasteur in Bordeaux, France (postal code 33000), operating from the Nouvelle-Aquitaine region. The company's trust tier is classified as harbour, the lowest verification band, with a response rate of 0.00% and no recorded response hours. These signals suggest limited active engagement through the platform, or that the listing may represent a brokering arrangement rather than direct mining operations. The address places Guimarts in a major French Atlantic port city with established maritime logistics infrastructure, relevant for coordinating West African bulk shipments.

The listing does not state mining assets, processing facilities, workforce size, annual revenue, or end-client references. Guimarts sources material from Guinea rather than extracting it, positioning itself as a trade intermediary. The supplier's direct language, including instructions not to contact them if unable to respond favourably to terms, indicates a preference for serious, ready-capitalised buyers. Buyers should conduct independent due diligence on Guimarts' corporate registration in France and request proof of offtake agreements or port access rights in Guinea before advancing beyond LOI stage.
