Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing heterocyclic alcohol impurities beyond specification
Exceeds purity limits for Chapter 29.14; becomes heterocyclic compound mixture.
If certified as urine diagnostic reagent
Diagnostic preparations for medical analysis exclude pure chemical classification.
If US goods returned after lab analysis abroad
Returned American goods may qualify for duty-free re-import.

Import Tips & Compliance
• ACS grade requires NIST-traceable certificates; ensure batch COA included in shipment
• Light-sensitive—declare special packaging to prevent degradation during ocean transit
• Laboratory end-use certification prevents pharmaceutical duty rate application
