New Marking Standards for Parcels Containing Hazardous Materials

Today the Federal Register published our Domestic Mail Manual (DMM^®) final rule that revises mailing standards to adopt new mandatory marking standards for parcels containing mailable hazardous materials that will align with revised requirements provided by the Department of Transportation (DOT). This final rule also provides terminology and categorization changes in response to DOT's pending elimination of the "Other Regulated Material"' (ORM-D) category and partial elimination of the "Consumer Commodity" category.

The effective date is January 1, 2013.
