Give suppliers one brief
A distributor may need the same rim diameter in several PCD and ET combinations. We map quantities to each center bore and finish so an offer for one fitment cannot stand in for all of them.

About Ronal sourcing
Ronal is an independent China procurement service, separate from wheel manufacturers and trademark owners.
How we work with buyers
Keep the decision with the buyer
One supplier can simplify finish matching and follow-up. Several suppliers can cover more fitments, with separate sample approvals and packing references to manage. We record those differences for buyer review.
Three habits at the desk
Name the version
Attach the drawing revision to each quote and sample. When the wheel offset changes, reopen brake clearance and mounting checks.
Identify the issuer
Record the supplier site for a system certificate and the lab, SKU and test conditions for a product report. Suppliers and independent providers issue those documents.
Keep exceptions visible
An unavailable finish, unresolved load rating or a revised supplier lead time goes back to the buyer for a decision.
What an evidence review looks like
Work with the coordination desk
Buyers, supplier quality teams and inspection providers can share their role and the decision they need to make.
