ITW Polymer Adhesives North America Lot Number Decoding

The 6 digit lot number represents the date of manufacture code for our products. The breakdown for lot 001051 is as follows:

001051 Is the first batch of that product manufactured on January 5, 2010.
510253 will be the third batch produced on October 25, 2015.

Note 1 : Our lot codes will repeat by decade but with our shelf life maximums there will not be any conflict dates.
Note 2: Shelf life is from date of manufacture in effect when stored correctly. Simply adding the number of months as stated on the product will tell you the shelf life expiration date.

Products are marked with both the lot number and the following statement:
  • “Shelf life is XX months from date of manufacture.” Or “Shelf Life” 10 Months

For the two lots above:

  • Lot 001051 would be at shelf life on November 5, 2010.
  • Lot 510253 would be at shelf life on August 25 2016.
