USEPA regulations at 40 CFR 261.4(a)(20) provide for a conditional exclusion from management as a solid waste – and therefore as a hazardous waste as well – for hazardous secondary materials used to make zinc fertilizers.  You can learn more about the full conditional exclusion here:  40 CFR 261.4(a)(20)  Hazardous Secondary Materials Used to Make Zinc Fertilizers.
