LERONA IMPORT & EXPORT LTD, a Korean‑based exporter specializing in mono‑ammonium phosphate (HS 310540) and related fertilizer products, recorded a single sizeable shipment in June 2024 of 21,686 kg (≈1.5 TEU) from Pusan to Tacoma, WA, destined for GROUPE HORTICOLE LEDOUX INC. This isolated but high‑value export signals a focused supply niche rather than broad volume activity, suggesting reliability for buyers needing consistent quality over large quantities. For prospective buyers, LERONA demonstrates clear product expertise, a stable partner network, and the capacity to serve North‑American markets with predictable lead times, making it a dependable source for specialty fertilizer inputs. Customs brokers should note the consistent use of HS 310540, a single loading port (Pusan) and a single discharge port (Tacoma), which yields streamlined documentation and predictable routing, facilitating efficient clearance. The limited shipment frequency reduces the risk of documentation variance, while the clear product‑HS code alignment supports accurate tariff classification and compliance checks.
