Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If standard commercial purity
Non-spectrograde non-alloyed zinc below 99.99% in next purity tier.
If pre-mixed for diagnostic reagents
Zinc prepared as lab reagents shifts to prepared chemical reagents chapter.
If cast into bars or rods
If shaped beyond unwrought forms like simple bars, moves to worked zinc articles.
