Tex. Alco. Bev. Code § 62.09

Regardless of any other provision of this code, a holder of a brewer's license may brew and package malt beverages or import them from outside the state, for shipment out of the state, even though the alcohol content, containers, packages, or labels make the beverages illegal to sell within the state. The licensee may export the beverages out of state or deliver them at the licensee's premises for shipment out of the state without being liable for any state tax on malt beverages sold for resale in the state.
