Cocoa shells have been used as a feed ingredient, but their theobromine content raises toxicity concerns for certain animals, particularly dogs and horses. If imported for animal feed use, USDA and FDA feed-ingredient regulations may apply in addition to standard customs requirements. Importers should verify the intended use and consult with a licensed customs broker or regulatory specialist before entry.

Beyond animal feed, cocoa shells are used as garden mulch (sold retail as 'cocoa hull mulch'), as a biomass fuel source, and in specialty food applications such as cocoa shell tea. Theobromine extraction for pharmaceutical use is a niche but established application. The specific end use can affect how the product is classified and which regulatory pathways apply at entry.
