Assembly Bill 437 mandates that retailers in Wisconsin provide a sales invoice or sales receipt that explicitly states the total cost of any tariffs imposed on consumer goods sold. The bill defines a retailer as any person who sold consumer goods with a gross value of $3,000,000 or more in the preceding calendar year. The terms "sales invoice" and "sales receipt" are also defined within the bill, referring to documents that list the consumer goods and their prices either before or at the time of sale.

The new section created by this bill, 100.10 of the statutes, outlines the requirements for retailers regarding tariff disclosure. This initiative aims to enhance transparency for consumers regarding the additional costs associated with tariffs on goods they purchase, thereby allowing them to make more informed buying decisions.
