Import Tips
• Submit EP certificate and impurity profile (<0.5% related substances) to customs; mismatch leads to 2933.99.9700 reclassification
• Declare as 'pharmaceutical reference standard' if for QC labs to differentiate from bulk API and avoid higher scrutiny
• Package in amber glass with desiccant; improper moisture control often triggers FDA rejection at entry
