Saint‑Gobain Gypsum SA de CV, an importer specializing in gypsum and related calcium sulfate products, has demonstrated a focused but consistent purchasing pattern from its primary supplier SAINT GOBTAIN PPC ITALIA SPA, accounting for all recorded shipments in 2021. Over the year the buyer executed five import shipments (totaling ~106 t) via the Napoli (Italy) loading port to the Miami (USA) unloading port, consistently employing HS Code 252010. Shipment frequency, while modest, shows a quarterly rhythm with each consignment averaging ~20 t and using a standard 2‑TEU container size, indicating stable demand and reliable order sizing. For suppliers, this translates into a dependable partner who maintains regular order volumes, adheres to a single sourcing strategy, and offers predictable payment cycles, suggesting potential for expanded procurement as market conditions evolve. For customs brokers, the buyer’s operations present low‑risk clearance: uniform HS‑code usage, repeat port pairs, and a clear product classification simplify documentation and expedite release, while the limited variation in partners and routes enhances forecasting of customs workload and compliance monitoring.
