Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If waste or scrap
Thallium waste/scrap has dedicated subheading 8112.13, separate from standards.
If integrated into lab instruments
Parts of analytical instruments containing thallium go to Chapter 90.
If US goods returned after processing
Reimported US-made thallium foil qualifies for duty-free under Chapter 98.
