Frequently asked questions
How do oxo plants manage rhodium inventory with you?
Precursor supply and catalyst-purge recovery run under one account: purge streams are assayed and the rhodium credited at the agreed fixing against fresh precursor deliveries.
How is pricing structured?
Quotes reference the day's metal fixing on assayed contained metal plus a stated conversion charge, and can be locked at order confirmation for recurring volumes.
What documentation is included?
Every lot ships with a certificate of analysis stating assayed metal content, plus an English SDS. ICP trace-metal panels are available on request.
