This bill increases the annual limit on the tax credit for qualified railroad track maintenance expenses (also referred to as the short line railroad tax credit) and expands eligibility for claiming the credit.

Covered platforms are prohibited from conducting market or product research on children under the age of 13, and may only conduct such research on those under the age of 17 with parental consent.
The bill provides for enforcement through the Federal Trade Commission and states.
The bill also requires online platforms to meet certain requirements before using algorithms that select, order, or prioritize information presented to users based on user-specific data not provided for that purpose.

This bill broadens the scope of pill machines that are subject to regulation under the Controlled Substances Act (CSA).

This bill requires persons who sell or deliver regulated machines to comply with the CSA's recordkeeping and reporting requirements, in addition to persons who manufacture, distribute, import, export, or purchase them.
The bill also expands regulated machines, for which transactions must be recorded and reported, to include critical parts of tableting and encapsulating machines such as dies used to mold pills and punches used to imprint markings and logos onto pills.
The bill requires serial numbers to be permanently affixed to encapsulating machines, tableting machines, and critical parts of tableting and encapsulating machines.
Finally, the bill prohibits, subject to criminal penalties, the (1) removal, alteration, or obliteration of any serial number affixed to a tableting machine, encapsulating machine, or a critical part; or (2) transportation, shipment, receipt, possession, distribution, delivery, sale, import, or export of any tableting machine, encapsulating machine, or critical part knowing the serial number has been removed, altered, or obliterated.
