Factory Code

Industry & Trade
Definition
A code identifying the factory that produced a box of cigars. Cuban factory codes are letter combinations that have been reassigned over time and were long treated as a trade secret, with published keys circulating among collectors.
Why it matters
Collectors track factory codes because construction quality and house character vary measurably between factories, even for the same marca.
In context
"Collectors chase certain factory codes for that marca and avoid others."
