“High thick crust leather” likely refers to a type of leather that is thicker than average and in a raw, unfinished state (i.e., crust leather). The term “high” may refer to the thickness of the leather, which is typically measured in ounces or millimeters.

Crust leather is often sold to manufacturers and designers who will further process and finish the leather to meet their specific requirements. The thickness of the leather can affect how it is used, with thicker leathers often being used for products that require greater durability, such as boots or belts.

It is worth noting that the term “high thick crust leather” is not a standardized term used throughout the leather industry, so its exact meaning may vary depending on the context in which it is used.
