CARTUCHOS COSTARRICENSES S A, a Costa Rican importer, specializes in plastic‑based ammunition components such as cartridges and related packaging, reflected by its primary HS code 520526. In March 2024 the buyer recorded a single but sizable shipment of 9,263 kg (≈1 TEU) from the Mexican loading hub of Caucedo to San Juan, Puerto Rico, sourced exclusively from supplier INDUSTRIAS TECNOS S A DE C V. This concentrated trade pattern signals strong, focused demand and a reliable partnership that suppliers can leverage for stable volume commitments. For customs brokers the transaction is straightforward: consistent HS‑code usage, a fixed loading‑and‑unloading port pair, and a clear documentation trail, facilitating predictable clearance cycles and minimal classification disputes. The buyer’s limited but high‑value import activity underscores both a niche market opportunity for related manufacturers and an efficient, low‑risk customs profile.
