Importaciones Barrera supplies a Colombian‑origin columbite‑tantalite concentrate commonly referred to as Coltan - Tantalium. The concentrate contains a tantalum pentoxide (Ta2O5) grade of 43.382 % and a measured tantalum (Ta) content of 35.527 % by weight. Trace elements include niobium (Nb) at 16.260 %, thorium (Th) 0.077 %, uranium (U) 0.138 % and lead (Pb) 0.426 %. The supplier ships the material in bulk, with a monthly availability of 15 tonnes.
Coltan from South America is valued for its relatively low natural radioactivity, a characteristic that aligns with industry expectations for capacitor‑grade ore. Typical high‑grade concentrates deliver Ta2O5 between 30 % and 50 % and keep impurity levels such as Nb below 20 % and Th under 0.1 %. The Colombian concentrate meets these ranges, offering a consistent composition that suits aerospace, medical device and semiconductor manufacturers. Standard industry practice packages the ore in sealed bulk bags or 200 kg drums to protect against moisture, which is usually limited to less than 0.5 %.
Buyers in the electronics sector use this material to produce tantalum capacitors, while aerospace firms employ it for high‑temperature components. Importaciones Barrera states that each shipment is accompanied by a certificate of origin, a royalty payment receipt and a technical data sheet per tonne. The listed price is US $80 per tonne, and the buyer may nominate any discharge port. Prospective importers should confirm the exact minimum order quantity and payment conditions directly with the supplier.

Before placing an order, importers should verify the exact tantalum pentoxide percentage and impurity profile by requesting a recent certificate of analysis. Confirm that the material complies with the low‑radioactivity requirements of your target market, and ask for any additional test reports the supplier can provide. It is also advisable to check the validity of the certificate of origin and the royalty payment receipt that the seller mentions.
The seller states a price of US $80 per tonne and offers flexibility on the discharge port, but the exact incoterm, lead‑time and payment schedule are not disclosed. Importers should negotiate the preferred incoterm - commonly FOB Bogota or CIF the destination port - and confirm the expected shipment window. Payment methods such as T/T against documents or a letter of credit should be agreed in advance to protect both parties.
Each shipment arrives with a technical data sheet, a certificate of origin and a royalty receipt, providing a baseline for quality verification. Buyers are encouraged to arrange an independent laboratory test for radioactivity and moisture content to ensure compliance with their own standards. Retaining all inspection reports and documentation will facilitate customs clearance and downstream quality audits.
