How does Puritan Products assign lot numbers and what do they mean?
Puritan's lot number consists of 11 digits. As you can see in the chart below, the first four digits of the lot number are the product code. The next three digits of the lot number represent the Julian date. The next two digits represent the last two digits of the year. The last two digits represent the sequence of lot numbers assigned that day.
|Product code||Julian Date||Year||Lot Sequence|
The example lot number above is for Sulfuric Acid, 96% that was packaged on May 7, 2013 and it was the first product that was assigned a lot number that day.
