Prior to placing your order we must have a valid tax-exemption certificate on file for your order to be tax-exempt. If you are tax-exempt and have not sent us your tax-exemption certificate, please send it via e-mail Brookfield.de@ametek.com. Please include your account number, bill-to, and ship-to address.  Once we verify your certificate, we will send you an email letting you know you can proceed with placing your order.
