The industry term for this is "plucking standard".
Making a list like that would be pretty difficult, because there is no legal requirement; each estate or bought leaf factory decides the standard on its own, based on the tradeoff between quality and price.
Also, tea blenders can modify the standard through various practices, like adding tips and removing stems to make a tea seem to have had a higher plucking standard than it really had.
Assuming that you are using whole or broken leaf tea (instead of CTC, fannings, or tea dust), you can examine the brewed leaves to help guess the plucking standard. Young tea leaves and old tea leaves can be quite different in size.
If you are dealing with tea estates rather than bought leaf factories or tea refiners, they will be more likely to be able to provide precise information on the plucking standard.
