To better understand the risks posed by improper ("undeclared") air shipments, we assessed what is known about their nature and frequency, what key mechanisms are in place to prevent their occurrence, and what the Department of Transportation (DOT) and the Postal Service do to enforce federal regulations for shipping dangerous goods by air. https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-03-22/html/GAOREPORTS-GAO-03-22.htm https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-03-22/pdf/GAOREPORTS-GAO-03-22.pdf GAO-03-22 https://www.govinfo.gov/app/details/GAOREPORTS-GAO-03-22 Other Written Product GAO-03-22; Aviation Safety: Undeclared Air Shipments of Dangerous Goods and DOT's Enforcement Approach; Air transportation operations Federal regulations Hazardous substances Inspection National preparedness Safety regulation Safety standards Transportation safety Public Law 107-71 Public Law 107-296 Title 49 Part 171 49 CFR Part 171
