Yingxia Cao

Yingxia Cao is a CBP-licensed customs broker operating out of Claremont, California, a city situated in the eastern San Gabriel Valley region of Los Angeles County. With proximity to the ports of Los Angeles and Long Beach — which together handle roughly 40% of all U.S. containerized imports — Cao is well-placed to assist importers navigating the commercial entry process through one of the nation's most active trade gateways.

For importers sourcing products from China, Southeast Asia, South Korea, Japan, or other Asia-Pacific suppliers, working with a locally based licensed broker in the greater LA corridor offers meaningful logistical and compliance advantages. Customs entry preparation under CBP Form 3461 and CBP Form 7501 requires accurate HTS classification, proper valuation, and timely filing to avoid delays at the port. Brokers operating in this region understand the volume and pace of cargo moving through these facilities.

Importer Security Filing — commonly known as ISF or the 10+2 rule — is a mandatory pre-arrival requirement for ocean shipments entering the United States. Ensuring ISF is submitted accurately and on time is a foundational compliance obligation for any first-time importer or established supply chain. Yingxia Cao, as a licensed broker, is authorized to file ISF and customs entries on behalf of importers as their designated agent of record.

For businesses looking to recover overpaid duties, understanding the duty drawback program under 19 USC 1313 is critical. Duty drawback refunds allow importers and manufacturers to reclaim up to 99% of duties paid on goods that are subsequently exported or destroyed. Working with a broker familiar with how to file duty drawback claims can recover significant costs for companies engaged in manufacturing, re-export, or substitution operations.

Additionally, importers should be aware of Section 321 de minimis provisions, which exempt low-value shipments under $800 from duties and formal entry requirements — a growing consideration for e-commerce and direct-to-consumer import operations.

Continuous customs bonds, CBP compliance programs, and prior disclosure procedures are additional areas where having a licensed broker as a resource can help importers proactively manage risk. Whether you are working through your first commercial entry or evaluating your existing import compliance program, a licensed customs broker in the Claremont and greater Los Angeles area like Yingxia Cao offers the credentials and CBP authorization needed to represent your interests before U.S. Customs and Border Protection.
