Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If packaged as complete calibration kit
Kits with instruments classify as laboratory apparatus parts.
If diagnostic reagent grade
Lab reagents containing rhenium become chemical diagnostic products.
If U.S. goods returned after analysis
Re-imported U.S.-origin standards qualify for duty-free under Chapter 98.
