More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the cesium-137 is in pure isotopic form without chloride compounding
Pure radioactive isotopes are classified under 2844.10, which takes precedence over compound headings per Section Note 1(A).
If the solution is a chemical product not specifically radioactive
If the specific activity is below the 74 Bq/g threshold, it may fall under residual chemical product headings rather than Chapter 28.
