Colored Modeling Plaster
Colored modeling plaster contains calcined gypsum with pigments for sculpting, casting, and educational craft projects. It qualifies for HTS 2520.20.00.00 as the pigments represent coloring only, with gypsum as principal component. Popular in art classrooms and hobbyist workshops for non-firing plaster sculptures.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing 30%+ set-accelerating colorants
Artist colors and plasters with substantial functional additives become Chapter 32 set color products.
If pigments simply coat uncalcined gypsum
Uncalcined base material with surface coloring remains crude gypsum classification.
If molded into craft figurines before import
Pre-formed plaster articles, even decorative, classify as finished goods under Chapter 68.

Import Tips & Compliance
• Confirm pigment content doesn't exceed coloring limits; high pigment levels risk Chapter 32 classification
• Specify 'for modeling use' on commercial invoices to distinguish from construction plasters
• Test for heavy metals if targeting children's craft market to meet toy safety import standards
