Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If chemically synthesized or purified
Synthetic disodium sulfate falls under inorganic chemicals in Chapter 28, not natural minerals.
If processed into fertilizers
Magnesium potassium sulfate fertilizers are classified by end-use in Chapter 31, not raw minerals.
If mixed with other mineral substances
Mineral substances not elsewhere specified but blended would fall under the broader 2530.90 category.
