B2B clients prioritize health safety above all. We guarantee that all our clays are sourced from authentic raw ores in Dingshu, Yixing, with zero chemical pigments or artificial additives. Pure clay, pure tea.

Mass-produced slip-casted pots lack the "breathability" of real Zisha. We strictly supply semi-manual and full-manual teapots, preserving the honeycomb structure of the clay that serious collectors demand.

From the high shrinkage of Zhuni to the delicate texture of Duanni, we apply material-specific QC standards and reinforced packaging to ensure zero damage during long-distance international shipping.

Maximize your ROI with our "Curated Classics." We recommend globally recognized shapes like Xishi and Shipiao for B2B starters, ensuring high turnover and lower inventory risks for your boutique.

Trust is the currency of high-end trade. We provide detailed material profiles and artist certificates for every piece. Let GuanInternational be your expert eyes in Yixing, providing the authenticity your brand stands for.
