Frequently asked questions
How is pricing structured?
Quotes reference the day's ruthenium price on assayed contained metal plus a stated conversion charge; ruthenium's low price among PGMs makes it the economical choice wherever it can do the job.
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.
Do you take back spent material?
Yes — spent catalyst, coating residues and off-spec lots are assayed on receipt and the recovered ruthenium credited against your next order.
