Frequently asked questions
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.
Do you supply matched bath chemistry?
We supply the Pd salt with certified metal content and chloride level; bath formulation stays with your chemistry vendor. Recurring plating lines can schedule standing deliveries against a forward metal fix.
Do you take back spent material?
Yes — spent catalyst, residues and off-spec lots are assayed on receipt and the recovered metal credited against your next order, closing the loop on your metal inventory.
