MI HB5637

Requires businesses in Michigan to publicly disclose any price adjustment resulting from U.S. or foreign government tariffs within 7 days of the tariff being imposed.

Mandates that tariff-related price increases be calculated as a percentage based on the pre-tariff price and displayed on consumer receipts in dollar amounts with the label "tariff charge."

Adds violations of the new tariff disclosure requirement (Section 3j) to the list of unfair, unconscionable, or deceptive trade practices under Michigan's Consumer Protection Act.

Clarifies that specific methods, acts, or practices are only exempt from the Consumer Protection Act if expressly authorized by state or federal law, not merely because they are part of a generally authorized transaction or subject to government regulation.
