Ccm Eng. Corp. supplies Coltan Ore Concentrate that contains 33 % Ta₂O₅ and 15 % Nb₂O₅ as measured by iTSCi‑certified assay. The concentrate originates from the Democratic Republic of Congo and meets a radioactivity limit of 0.5 % for the sum of ThO and U₃O₈. Each shipment is sized at forty metric tons and is packed in two standard 20‑foot containers. The material is accompanied by traceability documentation that complies with iTSCi standards.
In the mineral market this grade is classified as a high‑tantalum feedstock suitable for capacitor production and for alloying in aerospace superalloys. Typical industry specifications call for moisture below 0.1 % and a particle‑size range of 0‑10 mm. Bulk density for similar concentrates averages around 3.2 t m⁻³, which influences transport planning. Standard export packaging includes sealed wooden crates with moisture‑absorbing liners to preserve assay integrity.
Electronics manufacturers and alloy producers are the primary buyers of this concentrate. Ccm Eng. Corp. offers CIF delivery to the port of the buyer’s choice and requires a letter of credit payable on sight of inspection and bill of lading. Potential importers should confirm container loading conditions, assay report format, and any additional compliance documentation before finalising the order.

Confirm the container seal numbers, crate conditions and any required pre‑shipment inspections to avoid surprises at the destination port.
Logistics for this product are normally arranged on a CIF basis, meaning the supplier handles freight to the buyer’s nominated port. Because lead‑time is not disclosed in the listing, negotiate a realistic schedule and agree on the incoterm and payment terms - typically a letter of credit payable on sight of the inspection report and bill of lading.
Quality assurance should include a third‑party inspection at the loading port, focusing on moisture, particle size and radioactivity limits. Ensure that the inspection agency provides a signed report and that all customs documentation, including the origin certificate, is ready before the containers are released.
