Mimosa Tannin Extract Flakes from Mexico

Mimosa tannin extract, obtained from Acacia mearnsii bark, is a natural vegetable tanning agent used in the leather industry for producing soft, full leathers. Classified under HTS 3201.90.50.00 as 'other' vegetable tanning extracts, it is imported in flake form for easy dissolution. Its high tannin purity makes it ideal for drum tanning processes.
