Import Tips
• Differentiate from USP grade via specification sheet; technical grade still qualifies if primary vitamin use proven
• Test for pyridine odor/impurities; excessive contaminants trigger reclassification as chemical intermediate
• Declare CAS 59-67-6 prominently; generic 'vitamin powder' descriptions cause examination and delays
