Inquiry (采购产品): Sales Tax Exemption Certificate We have an invoice from August 2007 in which was short paid the tax amount. I have spoken to a few people in the office regarding the matter but have yet to hear back. Are you sales tax exempt? If so, we would like a sales tax exemption certificate for the state of California from your company to take care of this outstanding invoice. Please call me at 412-787-4662 with any questions or if you need a copy of the invoice. We appreciate your attention to this matter. **** Hidden Message ***** Jennifer Pittser 15230 Company: Calgon Carbon Corporation E-mail: jpittser@calgoncarbon-us.com **** Hidden Message ***** jpittser@calgoncarbon-us.com
