  • Proper rotation of the finished goods inventory is necessary
  • Products should be stored in a cool, dry area between 65ᵒF - 75ᵒF

Which Product Is Oldest?

In addition to proper product storage and care, it’s essential to understand Chromaline’s lot numbering system in order to use the oldest product first. It’s quite simple and we’re providing an array of tools to help you out.

  1. The first letter indicates the year the product was manufactured. For example: Q=2021, R=2021, S=2022, T=2023, U=2024, etc. (Note: The letter I and the letter O are skipped.)
  2. The next three digits indicate the day of the year. For example: 001=January 1, 152=June 1, 365=December 31
  3. All remaining digits are for internal use only.
