For security reasons, the US Postal Service has instituted new 
restrictions on both stamped First Class/Priority Mail and stamped 
international packages weighing more than 16 ounces.
        Any envelopes or packages weighing more than 16 ounces must be 
presented in person at a post office rather than simply stamped and 
deposited in a mailbox. If they are stamped and put in a US or an MIT 
mailbox, they will be returned to the sender rather than processed.
        However, MIT's Mail Services can handle both domestic and 
international packages for MIT-charged mail. Customers should put such 
packages in the special mail boxes labeled "Mail to be processed" or in 
the appropriate bins in the Distributed Mail Centers. Personal packages 
must be taken to a US post office to be weighed and processed.
        Most of MIT's international mail goes through a remailer for the 
fastest delivery abroad, and MIT Mail Services prepares the necessary 
paperwork for these deliveries. Members of the community will need to 
fill out a USPS customs form only in the following four cases: if you 
want surface mail, if the package contains anything except paper, if 
it's going to an APO or FPO address, or if it is a large package which 
must go by parcel post. MIT Mail Services will provide the customs 
forms.
        If you have questions about the new restrictions or how MIT Mail 
Services can help, call them at x3-6000.
