About Yingyun Zhu

Whether you're a first-time importer navigating CBP requirements or an established business managing recurring commercial entries, Yingyun Zhu can help ensure your shipments clear customs accurately and in compliance with U.S. trade regulations.

Yingyun Zhu is a federally licensed U.S. customs broker operating out of Ontario, California, with CBP filer code NJB. Ontario is a strategic hub for import logistics in the greater Southern California region — located just inland from the Port of Los Angeles and Port of Long Beach, which together handle the majority of U.S. imports arriving from Asia. Importers receiving goods through these ports frequently rely on brokers in the Inland Empire to manage customs clearance, entry preparation, and regulatory compliance before cargo moves into distribution.
For importers unfamiliar with the process, working with a licensed customs broker like Yingyun Zhu can be invaluable. A broker can prepare and submit CBP Form 3461 for immediate delivery, file the required Importer Security Filing (ISF) for ocean shipments, and classify goods under the correct HTS code — including categories like electronics, consumer goods, and general merchandise that flow heavily through the LA/Long Beach gateway. Accurate HTS classification is essential not only for determining duty rates but also for compliance with trade remedy orders such as Section 301 tariffs.
Zhu can also assist importers with continuous customs bond procurement, which is required for frequent importers and helps avoid delays at the border. For businesses importing lower-value goods, understanding Section 321 de minimis rules can reduce duty exposure, and a licensed broker can help determine when this threshold applies.
Importers who have overpaid duties in the past may also be eligible for a duty drawback refund under 19 USC 1313. A licensed broker familiar with the duty drawback program can help identify qualifying shipments and file claims with CBP to recover those funds. Additionally, if your business has identified a potential compliance issue, a prior disclosure to CBP may reduce penalties significantly — another area where professional broker guidance can make a meaningful difference.
Whether you are preparing your first commercial entry, building out a recurring import program, or conducting an internal review against CBP's focused assessment standards, Yingyun Zhu offers the licensing and local presence in Ontario, CA to support your customs needs. Importers searching for a customs broker near the Inland Empire, Los Angeles, or the greater Southern California area are welcome to reach out directly at 909-638-1879 or yingyun.zhu888@gmail.com.
