GB 1903.35-2018 is the Chinese national food safety standard for zinc acetate used as a food nutrition enhancer, made by reacting zinc oxide or zinc hydroxide with acetic acid.

It gives the chemical name, the structural formula of the dihydrate and both molecular formulas, C4H6O4Zn for the anhydrous salt and C4H6O4Zn·2H2O for the dihydrate, with relative molecular masses of 183.48 and 219.51 from the 2016 international relative atomic masses.

The sensory requirement is a white crystalline powder or flake, examined in a 50 mL beaker under natural light, and the standard then sets the physical and chemical indicators the product has to meet. It was issued on 21 June 2018 and has applied since 21 December 2018.
