(a) The comptroller in writing may authorize a customs broker to refund taxes collected under this chapter at export locations specified by the comptroller.
(b) The comptroller may issue an export identification card to a wholesaler or retailer. The card must contain the picture of the person to whom the card is issued. The comptroller may issue the card only if the wholesaler or retailer shows by clear and convincing evidence that the wholesaler or retailer is a citizen and resident of a foreign country and that any tangible personal property purchased in this state by the wholesaler or retailer is for export purposes only and is to be used or consumed outside the territorial limits of the United States. A wholesaler or retailer issued an export identification card may use the card only to facilitate the preparation of documentation by a customs broker under § 151.307(b). The comptroller may require a wholesaler or retailer applying for an export identification card to submit any information in any form the comptroller determines is necessary and to pay a fee in an amount the comptroller determines is necessary to pay for the cost of issuing the card.
