About Shu Chun Tsai
Shu Chun Tsai is a CBP-licensed customs broker based in Lomita, California, operating under filer code NXJ. Located in the South Bay area of Los Angeles County, this broker is positioned to serve importers moving goods through the ports of Los Angeles and Long Beach — two of the busiest cargo gateways in the United States. The LA/Long Beach port complex handles enormous volumes of consumer goods, electronics, apparel, and machinery, primarily sourced from Asia. Importers in the region often require support with customs entry preparation, HTS classification, ISF filings, and bond procurement. Shu Chun Tsai's proximity to these major ports makes this broker a relevant option for local importers seeking licensed customs representation for ocean and air freight shipments.
Shu Chun Tsai is a federally licensed U.S. customs broker holding CBP filer code NXJ, based in Lomita, California. Lomita sits within Los Angeles County's South Bay region, just miles from the Port of Los Angeles and Port of Long Beach — together forming the largest containerized cargo complex in the Western Hemisphere. This geographic positioning is significant for importers who need responsive, locally knowledgeable customs representation for shipments arriving from Asia, including China, Japan, South Korea, and Southeast Asia.
The ports of LA and Long Beach process hundreds of thousands of TEUs monthly, handling everything from electronics and consumer goods to textiles, apparel, and industrial machinery. An importer working with a broker licensed in this corridor benefits from familiarity with the local CBP field offices, port procedures, and the nuances of entry processing at these high-volume facilities. Shu Chun Tsai's licensure positions this broker to assist with customs entry preparation, accurate HTS code classification using the 10-digit tariff schedule, and compliance with CBP regulations.
For ocean freight importers, ISF filing — also known as the 10+2 filing or importer security filing — is a mandatory pre-arrival requirement, and timely submission is critical to avoiding CBP penalties. A licensed broker in the LA area can help ensure ISF deadlines are met and that entry documentation is in order before cargo arrives at the terminal.
Importers also frequently need guidance on bond requirements. Whether a single entry bond is appropriate for a one-time shipment or a continuous customs bond better suits a recurring import program, a licensed broker can help determine the right structure. For businesses exploring duty recovery opportunities, consulting a licensed broker about duty drawback programs — including manufacturing drawback and unused merchandise drawback — can yield meaningful cost savings over time.
With CBP's evolving enforcement environment around Section 301 tariffs, Section 232 steel and aluminum duties, and de minimis thresholds under Section 321, importers benefit from working with a broker who understands the current regulatory landscape. Shu Chun Tsai, holding an active CBP license in the Los Angeles market, represents a local option for importers seeking qualified customs brokerage services near the San Pedro Bay port complex.
