34 Pa. Code § 17.11
An employer or representative contractor may not furnish material to a contractor or homeworker until the employer or representative contractor has first secured a permit from the Department. A contractor may not furnish material to homeworkers until the contractor has first secured a permit from the Department. A permit of contractor shall entitle the contractor to accept materials to be given to homeworkers only from those employers or representative contractors who have been issued permits by the Department as employers or representative contractors to distribute homework. If the employer is a resident of a jurisdiction other than this Commonwealth, he shall cause his authorized agent in this Commonwealth to secure a permit as a representative contractor. When a person furnishes, or causes to be furnished, material to a contractor for the purpose of manufacture in whole or in part by homeworkers this person shall be considered an employer, and shall be licensed as such. Permits may be revoked if, after a hearing, it is determined that this chapter or the act of May 18, 1937 (P. L. 665, No. 176) (43 P. S. §§ 491-1-491-24) or act of May 13, 1915 (P. L. 286, No. 177) (43 P. S. §§ 41-71), have been violated.
