Compressed Gas Cylinder Safety and Oversight Improvements Act of 2023

HR 3404 requires the U.S. Department of Transportation to strengthen oversight of foreign manufacturers producing compressed gas cylinders for hazardous material transport in the U.S. It mandates annual inspections of these manufacturers, shortens initial approval periods to one year (with a possible five-year option under strict conditions), and requires applicants to disclose past penalties or criminal history. The bill also adds new disclosure requirements for applicants, including whether they’ve faced civil penalties, delinquent payments, or are listed on government watchlists. Additionally, it requires public comment periods for applications and annual publication of approved manufacturers' lists to increase transparency.
