Quick Service Guide 430
January 22, 2012
There are two categories of prices for First-Class Package Service commercial parcels: commercial base and commercial plus. For a complete list of commercial First-Class prices, see Notice 123–Price List.
First-Class Package Service may be used for any mailable item including advertisements and lightweight merchandise, except that parcels mailed at commercial base prices are not sealed against inspection and may not contain documents or personal correspondence, except that such parcels may contain invoices, receipts, incidental advertising, and other documents that relate in all substantial respects to merchandise contained in the parcels.
Eligibility Standards (433.3.0)
Mailings of 500 or more addressed pieces, sorted and marked as described below. All pieces must meet the physical standards for parcels (401).
Addresses on all pieces must be updated within 95 days before mailing through a USPS-approved address update method (e.g., ACS, NCOALink, FASTforward, or the appropriate ancillary service endorsement except Forwarding Service Requested, under 507.1.5).
