Blackstrap molasses is the final byproduct after maximum sugar extraction, with low residual sucrose and a strong, bitter flavor — used primarily in animal feed and fermentation. High-test molasses (also called high-gravity or inverted molasses) is produced directly from cane juice without full crystallization and retains higher fermentable sugar content. These distinctions can affect HTS classification and duty treatment, so importers should document the production method and sugar content with the supplier.

Importers should obtain a certificate of analysis from the foreign supplier specifying Brix reading, total sugars, ash content, and whether the product is edible or feed grade. These parameters help determine the correct HTS subheading and support any FDA or USDA feed-ingredient review. A licensed customs broker familiar with agricultural byproducts should review the entry.
