Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If derived from tapioca starch
Subheading specifies source starch; tapioca-derived OSA uses potato/other subheading.
If highly polymerized or hardened
Chapter excludes hardened proteins/starches, directing them to synthetic polymers in 3913.
If pre-mixed into food preparations
If incorporated into finished food products, it falls under Chapter 21 preparations rather than pure modified starch.

Import Tips & Compliance
• Provide chemical modification specs (e.g
• octenyl succinic anhydride treatment) to justify modified starch status
• Ensure FDA GRAS status documentation for food use to facilitate entry
• Avoid common pitfall of mislabeling as plain starch, which shifts to heading 1108
