Compressed Gas Cylinder Safety and Oversight Improvements Act of 2025

This bill tightens safety rules for gas cylinders made overseas that are used to carry hazardous materials in the U.S. It shortens most approvals to one year and allows a five-year approval only if the maker meets extra checks and stays in good standing. The Department of Transportation (DOT) can suspend or end approval if a company blocks inspections or lies on its application. DOT must also post a public notice when a company applies, allow 30 days for comments, and publish a yearly list of approved foreign manufacturers. Anyone with evidence can ask DOT to reevaluate a company’s approval if there are signs of unsafe or false claims .

Inspections may be done annually when there is good cause. DOT can ask for test and production records, take random samples, and make companies pay inspection costs. Applications must answer new questions, including past safety fines, unpaid penalties, links to certain government watch lists, and trade orders. DOT can deny, suspend, or end approval based on these answers or other misrepresentations. Overall, the goal is to keep unsafe or dishonest makers out of the U.S. market and make cylinder safety more transparent to the public .

Key points:

• Who is affected: Foreign companies that make compressed gas cylinders for hazardous materials shipped in the U.S., and U.S. communities relying on safe transport .
• What changes: Shorter approval periods, stricter inspections, public input, tougher questions on applications, and the ability to suspend or end approval for blocking inspections or giving false information .
• When it happens: DOT must set up the public reevaluation process and update inspection rules within set deadlines after enactment, and publish the approved manufacturers list annually .
