Pregelatinized Corn Starch
Pregelatinized corn starch is a modified starch that has been cooked and dried to allow instant thickening when mixed with cold water. While it is a modified starch, it may be classified under tariff item 3505.10.90 as 'other' if not specifically pregelatinized, though the sibling item 3505.10.20 specifically covers pregelatinized starch.
