CASTELMAC SRL, an Exporter‑Supplier specializing in metal castors, mounting hardware, refrigeration accessories and related machinery, has demonstrated a focused trade pattern with a handful of repeat buyers, chiefly THE DELFIELD COMPANY and, intermittently, GRUPO ALPHA SIMET S.A. DE C V. Over the past 14 months shipments have been low‑frequency but predictable, averaging 1‑2 containers per month from the Genoa (IT) loading hub to New York/Newark ports, with occasional loads from La Spezia (VE) to Miami. HS‑code usage is consistent, dominated by 830220 (castors), 841899 (refrigeration parts), 841850 and 847621, indicating a stable product classification that eases customs coding. Total monthly weights range from modest 32 kg parcels to a peak of 13.5 t in July 2023, suggesting capacity to handle both small orders and sizable bulk deliveries. For Buyers, CASTELMAC offers reliable, niche‑specific components with an evident preference for North‑American markets, while Customs Brokers benefit from the company’s regular port routes, repeat HS codes and predictable documentation, supporting efficient clearance and low variance in duty assessment.
