Yixing Purple-clay Ware and Traceable Sales

Dingshu is Yixing's centre for purple-clay making and trade, but the GI's permitted origin follows the current Yixing jurisdiction and its rules, not the town alone. CNIPA Notice 660 of 2026 lists Yixing Aiyi Art Ceramics, Yixing Taoyi Cultural Development and Yixing Nenggong Yajiang Zisha Culture as separate users of the Yixing Zisha mark, with distinct registration codes. Aiyi is involved in a purple-clay and wine-vessel research partnership, while Taoyi runs traceability services and a digital ceramics park. For Nenggong Yajiang, the public evidence here establishes mark approval, not production volume or sales. Local protective legislation and association rules govern clay, craftsmanship and traceability; they are not a separate SME-cluster award. A buyer should verify each item's authorised mark, clay, maker, method, test record and physical match.
