Sebastian Lopez S. A supplies Coltan Ore extracted in Colombia. The ore is reported to contain Ta2O5 between 34 % and 44 % as indicated by the supplier. It is presented as a concentrate suitable for further metallurgical processing. The company notes that the material is traded under HS Code 2615.90 for international markets.
In the Colombian mining sector, concentrates with a Ta2O5 range of 34‑44 % are regarded as medium to high grade, fitting the input specifications of many smelters. Typical industry parameters include particle sizes up to 6 mm and moisture levels of 4‑7 % to maintain bulk stability. Assays are commonly performed by ICP‑OES to verify oxide percentages. These characteristics align with the requirements of electronics, aerospace and medical‑device manufacturers that source tantalum raw material.
Potential buyers include capacitor producers, aerospace alloy fabricators and manufacturers of medical implants that need reliable tantalum feedstock. Trade is usually arranged on FOB or CIF terms, with bulk bag or containerised shipment, but exact incoterms, payment conditions and lead‑time estimates must be clarified with Sebastian Lopez S. A. The supplier emphasizes readiness to meet smelter specifications, yet buyers should request detailed assay documentation before finalising a purchase.

Prior to ordering, buyers should obtain a recent assay certificate that confirms the Ta2O5 range and any other measured oxides, as well as a certificate of origin confirming Colombian mining provenance. Verifying these documents helps meet both regulatory requirements and buyer quality standards.
Logistical planning for Colombian ore typically involves shipment from ports such as Buenaventura or Cartagena. Importers need to agree on Incoterms - FOB, CIF or others - and clarify the expected lead time, which depends on mining schedules and vessel availability. Payment terms, including letters of credit or staged payments, should be documented in the sales contract.
Quality assurance commonly includes third‑party inspection at the loading port and sampling of the bulk cargo before departure. Requesting an independent laboratory test - such as ICP‑OES - on the sampled material ensures the ore meets the declared specifications. Maintaining complete documentation, including the commercial invoice, packing list, assay report and origin certificate, is essential for smooth customs clearance and downstream processing.
