RoHS compliant tin plating

Can anyone tell me if tin plating (97% tin) is considered RoHS compliant?
We have recently changed our zinc plating from Yellow dichromate to clear zinc to conform to RoHS compliance and today I had a customer question whether the 97% tin plating would be compliant.

The regulated metals are cadmium, lead, mercury, and hexavalent chromium. If the tin is 99.9 percent lead-free then it ought to be okay.
