Unlike other bullion items that are produced into bars or coins, rhodium is also available in a powdered format, known as Rhodium Sponge. Below you’ll find more information about this unique product, including how to sell back Kitco Rhodium Sponge previously purchased from us.
Kitco Rhodium Sponge is a Kitco-exclusive product. Pure rhodium, viewed magnified, appears porous and powdery. This is why it is known as “sponge” in industry parlance. Kitco Rhodium Sponge is pure rhodium powder (.999+ fine) packaged in tough, tamper-proof pharmaceutical-grade plastic bottles. In addition to a unique serial number, each bottle’s label bears indications of its contents’ net weight and purity.
Currently, we only buy back Kitco Rhodium Sponge and no longer sell it. If you already own any Kitco Rhodium Sponge and wish to sell it or covert it into rhodium Pool, please call 1 877 775-4826 or 514 313-9999.
The Kitco Chain of Integrity is a process by which rhodium sponge purchased from Kitco never leaves the possession or control of recognized suppliers, transporters and facilities. When you choose to keep your Kitco Rhodium Sponge within the Kitco Chain of Integrity, it is sent for storage on your behalf directly to a Kitco Recognized Storage Facility of your choice using a Kitco Recognized Secure Transport Provider. When you desire to sell back your Kitco Rhodium Sponge from within the Kitco Chain of Integrity, it is shipped back to us direct from the Kitco Recognized Storage Facility using a Kitco Recognized Secure Transport Provider.
Kept within the Kitco Chain of Integrity, Kitco Rhodium Sponge is thus assuredly pure and safe from unauthorized tampering that could result in a substantial depletion of its resale value (for details, see, “What price will I receive when I sell my Kitco Rhodium Sponge?”).
To ensure your Kitco Rhodium Sponge remains within the Kitco Chain of Integrity, you can choose to have it securely stored at our Kitco Recognized Storage Facility in the U.S. through our Kitco Allocated Storage program. This global precious metals storage solution guarantees that your rhodium sponge will be fully segregated and allocated at a COMEX-approved facility, providing you with peace of mind and top-tier security.

The Kitco Chain of Integrity is considered broken when:
If a bottle is tampered with while in a Kitco Recognized Storage Facility, it will need to be assayed at a Kitco facility before a price can be confirmed. All shipping, insurance and assay charges will be your responsibility.
Storage fees covering insurance and handling costs are applicable. Costs vary depending on the Kitco Recognized Storage Facility you choose.
Yes, you may use any storage provider other than a Kitco Recognized Storage Facility. However, this will break the Kitco Chain of Integrity and negatively impact the price at which you would be able to sell your rhodium.
You cannot sell your Kitco Rhodium Sponge from within the Kitco Chain of Integrity unless it has already been delivered to a Kitco Recognized Storage Facility.
To sell us your Kitco Rhodium Sponge when the Kitco Chain of Integrity is intact:

†Note that it can take up to two business days for your Kitco Recognized Storage Facility to transfer your Kitco Rhodium Sponge to us.
‡Your payment will only be issued when your Kitco Recognized Storage Facility confirms that your Kitco Rhodium Sponge has been transferred to us, that it never left the Kitco Recognized Storage Facility and that its seals are intact.

Kitco’s buyback price will vary depending on whether or not the Kitco Chain of Integrity is intact.
Please note that the assaying process is destructive and materials that are subjected to it cannot be returned to you in their original condition.

No, holdings from a Kitco Rhodium Pool - Metal Account cannot be converted into or transferred to Kitco Rhodium Sponge because Kitco Rhodium Sponge is no longer available for purchase.
As long as your Kitco Rhodium Sponge is within the Kitco Chain of Integrity, we will convert your Kitco Rhodium Sponge into a Kitco Rhodium Pool - Metal Account ounce for ounce. If your Kitco Rhodium Sponge is outside the Kitco Chain of Integrity, the calculation will be based on purity and whether or not the bottles are tampered with. You will lose the fabrication fees.

Yes, you can sell rhodium bars and coins sourced from recognized mints and refiners to Kitco. However, the price we pay for it will depend on several factors such as the source and purity of the metal as well as the need for assaying it (if applicable). Kitco does not purchase rhodium sponge that was purchased from external suppliers.
