Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If carbonate-adulterated for specific uses
Carbonates of inorganic bases are 2836; mixtures exceeding purity thresholds reclassify per Chapter note 2 exclusions.
If for use as sodium hydroxide substitute in low-purity
Impurities making it akin to caustic soda shift to 2815; strict chemical definition enforced.
If fertilizer-grade with nitrogen/phos additives
Chapter note excludes Chapter 31 mixtures; fertilizer blends go there.
