Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If lysine component dominates classification consideration
Amino acid salts might be argued under oxygen function amino compounds if organic base prevails.
If imported as sterile injectable solution
Medicaments in measured doses for injection classify in chapter 30 regardless of active purity.
If multi-component buffer mixture
Salts in complex buffers exceed simple salt definition of note 4(C).
