Manufacturers shall, whenever practicable, be required to mark the unit or container with the month and year of manufacture or production and the batch number on all shelf-life items (60 months or less) procured from other than GSA sources. Whenever practical, the supplier shall be required to ship or deliver material within a given number of months from the date of manufacture or production. These “age on delivery” requirements should not be imposed in such a manner as to unduly restrict competition at any trade level. The following guidelines are suggested as appropriate for most shelf-life items:
25 mos. or more |
6 mos. |
19 to 24 mos |
4 mos. |
13 to 18 mos |
3 mos. |
7 to 12 mos |
2 mos. |
6 mos. or less |
1 mo. or less. |
