4168 - Sales by employer-producer to employees.

     § 4168.  Sales by employer-producer to employees.        In any case where under the provisions of a contract it is     provided that solid fuel be sold at cost by an employer-producer     to his employees for their own use and consumption, the solid     fuel may be sold by cubic contents instead of weight, but no     solid fuel so sold shall be transported over the highways of     this Commonwealth from the place of production to the residence     of the employee unless the operator of the vehicle possesses a     certificate of origin. The certificates of origin shall contain     such information as may be prescribed by the department and     shall be signed by the producer or the producer's agent, and a     copy of each certificate shall be kept at the place of     production for at least two years.
