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 previous 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 in paper or electronic form.

The new section created by this bill, 100.10, outlines the requirement for transparency regarding tariff costs in sales transactions. This aims to inform consumers about the additional costs associated with tariffs on the goods they purchase, thereby enhancing consumer awareness and understanding of pricing.
