About WILLIAM MELVIN STRINGFIELD
William Melvin Stringfield is a licensed U.S. customs broker based in Santa Ana, California, operating under CBP Filer Code 761. Located in the heart of Southern California's import corridor, Stringfield is positioned to assist importers moving goods through the Ports of Los Angeles and Long Beach — two of the busiest container ports in the United States. Whether you are a first-time importer or an established business managing high-volume shipments from Asia, Stringfield offers the regulatory knowledge needed to navigate CBP requirements, classify goods under the Harmonized Tariff Schedule, and keep cargo moving efficiently through customs. Importers in Orange County and the greater Los Angeles area looking for a licensed customs broker can reach Stringfield directly by phone at 213-436-5229.
William Melvin Stringfield holds an individual CBP customs broker license and operates out of Santa Ana, California — a strategically significant location for importers throughout Orange County and the broader Los Angeles metropolitan area. With proximity to the Ports of Los Angeles and Long Beach, which together handle roughly 40% of all U.S. containerized imports, Stringfield is well-situated to assist businesses importing from Asia, including electronics, consumer goods, textiles, apparel, and machinery.
For importers seeking help with commercial entry customs CBP processes, Stringfield can assist with the preparation and submission of customs entries, including CBP Form 3461 (entry/immediate delivery) and related documentation. Accurate HTS code classification is foundational to every customs entry — determining the correct HTS code meaning and applicable duty rate is critical to avoiding costly delays or penalties. Whether you are importing electronics and need the right HTS code for electronics, or sourcing apparel from overseas manufacturers, proper tariff classification protects your business.
Importer Security Filing (ISF) — commonly called the 10+2 filing — is a mandatory pre-shipment requirement for ocean freight. Stringfield can manage ISF filing on behalf of importers to ensure CBP compliance well before cargo arrives at port. For businesses that import regularly, a continuous customs bond is typically the most cost-effective bonding solution, covering all entries throughout the bond year rather than requiring a single-transaction bond for each shipment.
Importers who manufacture or export goods that incorporate previously imported materials may qualify for refunds through the duty drawback program under 19 USC 1313. Understanding how to file duty drawback and recovering those funds requires careful documentation and knowledge of CBP procedures — and is an area where working with a licensed broker can deliver meaningful financial returns.
Additionally, importers in Southern California should be aware of the section 321 de minimis exemption, which allows low-value shipments (currently under $800) to enter the U.S. duty-free. For e-commerce businesses and smaller importers, understanding how this provision applies to your shipments can create meaningful savings.
If your business has identified a potential compliance issue, a prior disclosure CBP submission can significantly reduce or eliminate penalties — another area where professional guidance from a licensed broker is valuable. Companies selected for a focused assessment CBP customs audit will also benefit from working with experienced customs professionals.
