Heading 3505

Dextrins and other modified starches (for example, pregelatinized or esterified starches); glues based on starches, or on dextrins or other modified starches

6 declarable lines

Heading 3505 covers dextrins, other modified starches, and glues based on starches, dextrins, or other modified starches. The heading splits first between dextrins and other modified starches in 3505.10 and glues in 3505.20. Within 3505.10, the line depends on whether the product is a dextrin or another modified starch and on the starch source, such as corn or potato.
