Rice starch does not have its own named subheading and falls under 110819 (Starches, NESOI), the residual subheading for starches not specifically named elsewhere in the heading.

Inulin is a fructan (a polymer of fructose units) rather than a glucan, so it is chemically distinct from starch and has its own dedicated subheading (110820). Products marketed as 'chicory fiber' or 'fructooligosaccharides' may or may not qualify as inulin depending on chain length and degree of polymerization; a binding ruling can resolve borderline cases.
