Do the regulation changes affect US Postal mailings?
Yes! Effective June 12, 2003, the US Postal Service (USPS) adopted changes in the mailing standards for the packaging and classification of infectious substances. These changes align the USPS standards with the current international standard for the transport of hazardous materials. The initial phase-in period was through January 1, 2004 so now all USPS mailings must conform to the new mailing standards.
