TRK Customs Service Inc is a federally licensed U.S. customs broker headquartered in Diamond Bar, California, a city situated in the eastern San Gabriel Valley within Los Angeles County. The firm holds an active CBP broker license under filer code 9AR, authorizing it to transact customs business on behalf of importers before U.S. Customs and Border Protection.
Diamond Bar's location places TRK Customs Service in a strategically significant position for import logistics. The firm sits within close range of the Ports of Los Angeles and Long Beach, which together form the largest port complex in North America and serve as the primary entry point for goods manufactured in Asia — particularly from China, South Korea, Japan, Vietnam, and Taiwan. Importers shipping electronics, consumer goods, textiles, machinery, and general merchandise through these ports frequently work with customs brokers in the LA/Inland Empire region to manage their entry filings.
For first-time importers and established commercial shippers alike, working with a licensed broker like TRK Customs Service means having a qualified professional handle the complexities of commercial entry with CBP. This includes preparing and submitting entry documentation, determining accurate HTS codes (understanding HTS code meaning is critical to correct duty assessment), and ensuring tariff classifications are applied correctly to avoid costly delays or penalties.
TRK Customs Service can assist clients with importer security filing (ISF) submissions, which are required 24 hours before cargo is loaded at a foreign port. Proper ISF filing is a federal requirement for ocean shipments entering the U.S., and errors can result in CBP holds or liquidated damages. The firm is also equipped to advise importers on import bond requirements, including whether a single-entry bond or a continuous customs bond better fits their import volume and frequency.
For importers moving lower-value shipments, TRK can provide guidance on Section 321 de minimis entries and Type 86 entry customs procedures, which allow qualifying shipments valued at $800 or less to enter duty-free. As e-commerce and direct-to-consumer importing have grown, understanding these entry types has become increasingly important for businesses operating in the Southern California market.
Additionally, businesses that have previously overpaid duties may benefit from consulting TRK about duty drawback programs. A qualified duty drawback broker can help importers recover duties paid on goods that are subsequently exported or destroyed — a legitimate refund mechanism that many companies overlook. If your company believes it may qualify, a prior disclosure to CBP or a formal drawback claim may be worth exploring.
TRK Customs Service Inc can be reached by phone at 909-348-0040. Importers searching for a customs broker near me in the Diamond Bar, Pomona, Chino, or Walnut areas of Southern California may find TRK's location convenient for in-person consultation and ongoing customs compliance support.
