Marval Infante offers Tantalum Ore Concentrate (Ta2O5) in powder form, sourced from mining operations in the United States, Brazil and Curacao. The concentrate is certified by Alex Stewart for quality assurance and is packed in ASA sealed drums for secure transport. The product is listed as a strategic mineral commodity with current market‑driven pricing. This listing provides the material composition and packaging details but does not disclose a minimum order quantity.
Tantalum ore concentrate typically contains 99.5% Ta2O5 with particle sizes ranging from 0 to 150 µm, which meets the requirements of most capacitor and superalloy manufacturers. Standard moisture content is kept below 0.5% to preserve chemical stability during storage. The bulk density of the powder is usually around 3.8 g cm‑3, allowing efficient handling in bulk shipments. These industry norms complement the supplier’s certification and ensure compatibility with downstream processing.
The concentrate is primarily used in electronics for tantalum capacitors, in aerospace for superalloys, and in medical devices such as surgical instruments. Importers typically request ASA sealed drums and may specify Incoterms such as FOB or CIF depending on logistics preferences. Because the listing does not state lead time or payment terms, buyers should confirm these details directly with Marval Infante before placing an order.

Before confirming a purchase, verify the origin of each batch by requesting a material origin statement that details the mining locations in the United States, Brazil or Curacao. Ask for the latest Alex Stewart certification and an assay certificate confirming the Ta2O5 purity level. Ensure that the supplier can provide the HS code 260490 and that the ASA sealed drums meet your storage requirements. Clarifying these points reduces the risk of non‑conforming shipments.
Discuss preferred Incoterms early; common choices for mineral concentrates are FOB Weston port or CIF destination, depending on your logistics network. Request an estimated lead time for drum preparation, loading and customs clearance, as the listing does not specify this information. Confirm acceptable payment methods, such as irrevocable LC at sight or documentary collection, and any required pre‑payment percentages. Aligning these terms prevents unexpected delays or financial exposure.
Plan for third‑party inspection either at the loading port or on arrival, focusing on assay, moisture and drum integrity. Request the supplier’s quality management procedure and any test reports generated during production. Ensure that the shipping documents include a commercial invoice, packing list, certificate of origin and the Alex Stewart certification copy. These documents support smooth customs clearance and downstream quality assurance.
