METALES UNZUETA II S L, Exporter of mineral ash (HS 262019), recorded a single shipment in April 2025 from Algeciras, Spain to New York/Newark, totaling 23.6 t and 1.5 TEU, destined for Zinc Industrias Nacional SA. Although the volume is modest, the trade pattern shows a clear port‑to‑port route and consistent HS‑code usage, indicating disciplined documentation and low customs friction. For Buyers, the company offers a niche product with reliable traceability, suitable for industries requiring high‑purity ash, and the single recorded transaction suggests capacity for scaling if demand grows. For Customs Brokers, the predictable loading/unloading ports, stable HS‑code declaration, and the absence of reported holds simplify clearance processes, allowing efficient handling of future shipments as volumes increase.
