Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for diagnostic or lab reagent use
Lab reagents not primarily pesticidal classify as diagnostic reagents in 3822.
If not explicitly pesticidal end-use
General 'other' aromatic heterocyclics without pesticide specification use residual code.
If personal effects or samples under 5kg
Small non-commercial lab samples may enter duty-free under article processing provisions.
