SK EL SALVADOR S A, an import‑driven buyer focused on kraftliner paper products, has demonstrated a narrow but consistent trade pattern with Swedish supplier Smurfit Kappa Kraftliner Pitea, concentrating shipments in early 2021. Both February and March loads originated from Bremen, Germany (Port 42870) and were discharged at Charleston, SC (Port 1601), using 12–20 TEU per voyage and total weights of 117 t and 195 t respectively, under HS Codes 480411 and 480419. For suppliers, the buyer’s repeat engagement with a single high‑quality kraftliner source signals dependable demand in the U.S. southeastern market, albeit at modest scale, offering a foothold for expansion or complementary product lines. For customs brokers, the predictable Bremen‑to‑Charleston corridor, stable HS‑code usage, and clearly documented freight, demurrage and detention terms convey high clearance efficiency and low risk of classification disputes, enabling streamlined customs processing and reliable duty budgeting.
