Iowa Code § 208A.4

1. Before any antifreeze is sold, exposed for sale, or held with intent to sell within this state, a sample of the product must be inspected by the department of agriculture and land stewardship. Upon application of the manufacturer, packer, seller, or distributor and the payment of a fee of twenty dollars for each brand of antifreeze submitted, the department shall inspect the antifreeze submitted. If the antifreeze is not adulterated or misbranded, if it meets the standards of the department, and is not in violation of this chapter, the department shall give the applicant a written permit authorizing the sale of such antifreeze in this state until the formula or labeling of the antifreeze is changed in any manner.

2. If the department finds at a later date that the product to be sold, exposed for sale, or held with intent to sell has been materially altered or adulterated, a change has been made in the name, brand, or trademark under which the antifreeze is sold, or it violates the provisions of this chapter, the department shall notify the applicant and the permit shall be canceled forthwith.
