The key distinction is the nature of the binder: 59227 applies when starch, dextrin, or another modified starch is the primary adhesive agent. If the formulation relies principally on a synthetic polymer, rubber, or other non-starch binder — even if starch is present as a filler or modifier — the product is more likely to fall under the prepared adhesives heading (59229).

Starch-based glues are generally classified as non-hazardous under standard transport regulations, but importers should confirm whether the specific formulation contains any additives (biocides, solvents, or preservatives) that trigger OSHA Hazard Communication or DOT hazardous-materials requirements. A Safety Data Sheet aligned with GHS standards is standard commercial practice for bulk shipments.
