The Shanghai Futures Exchange (SHFE) has opened a public consultation on revisions to its zinc futures contract and business rules. The proposed changes include updating the deliverable grade version for zinc ingots, specifically revising the standard from "GB/T 470-2008" to "GB/T 470-2026" in the "Shanghai Futures Exchange Zinc Futures Contract" and its appendices. Additionally, the revisions propose adding a provision to Article 22 of the "Shanghai Futures Exchange Zinc Futures Business Rules" stating that "zinc ingots used for zinc futures delivery may be stored outside warehouses."
