Yes. A manufacturer or importer of a taxable medical device may, in certain circumstances, sell a taxable medical device tax-free for use by the purchaser for further manufacture (or for resale by the purchaser to a second purchaser for further manufacture), or for export (or for resale for export). To make a tax-free sale for further manufacture or export, both parties to the sale must be registered with the IRS. Form 637, Application for Registration for Certain Excise Tax Activities, is used for the registration process. For more information on the Form 637 registration process, see the 637 Registration Program at IRS.gov.
