Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If converted to glycoside form
Sugar glycosides and salts thereof classify under heading 2932 rather than pure sugars.
If labeled as radiochemical tracer
Carbon-14 labeled D-Arabinose for metabolic studies falls under radioactive chemical preparations.
If when supplied as lab reagent kit component
Pre-measured aliquots in multi-component analytical kits classify as diagnostic reagents.
