FILTER MASTER CO LTD, an Exporter of industrial filters and related oil products, consistently ships 8‑11 container loads per month from Pusan, Korea, to U.S. West Coast gateways—primarily Long Beach (CA) and secondary Los Angeles, Houston, New York and Seattle—with monthly weights ranging from 58 t to 89 t and TEU between 12‑17. The top buyer, PREMIUM GUARD INC, accounts for 100 % of recent shipments, indicating a strong, repeat demand and stable order cadence. Products are concentrated on filter assemblies and oil‑related items, classified under HS codes 481200.0, 401693 and 842123, which the exporter uses uniformly across filings, simplifying tariff treatment and reducing clearance delays. For buyers, this translates into a dependable supply pipeline, predictable lead‑times and a focused product portfolio that can scale with industrial growth. For customs brokers, the repetitive port‑of‑loading, consistent HS‑code usage and single‑partner pattern enable streamlined documentation, high predictability in entry processing and low risk of compliance issues, supporting efficient customs clearance.
