MICHIO NAKAYAMA

Michio Nakayama, operating as Seishou Customs Brokerage, is a CBP-licensed customs broker (filer code B7Y) located in Lomita, California. Lomita sits within the South Bay region of Los Angeles County, just minutes from the Port of Los Angeles in San Pedro and the Port of Long Beach — together forming the largest port complex in the Western Hemisphere. This location makes Nakayama a practical choice for importers regularly clearing shipments arriving by sea from Asia, including Japan, China, South Korea, Taiwan, and Southeast Asian manufacturing hubs.

For importers navigating U.S. import requirements, working with a locally based broker near the port of entry offers real logistical advantages. Customs entry preparation, HTS code classification, and timely filing through the CBP ACE portal are core components of the clearance process. Accurate HTS code classification — using the USITC tariff database and HTS code classification guides — is essential to ensuring correct duty assessment and avoiding costly delays or penalties. A licensed broker helps importers identify the correct classification, whether for electronics, consumer goods, machinery and equipment, textiles and apparel, or other product categories commonly arriving at Los Angeles-area ports.

Seishou Customs Brokerage can assist importers with Importer Security Filing (ISF) submissions, which are required at least 24 hours before cargo is loaded at the foreign port. Compliance with ISF requirements is one of many areas where having an experienced, CBP-licensed broker on your side reduces risk. Nakayama is also positioned to advise on continuous customs bond requirements, which are typically required for importers with annual import activity exceeding $50,000 in duties, taxes, and fees.

Membership in the Los Angeles Customs Brokers and Freight Forwarders Association (LACBFFA) signals active engagement with the local trade community and access to current regulatory updates — an important factor as trade policy, Section 321 de minimis rules, and ACE portal procedures continue to evolve. Importers concerned with customs compliance audits or duty drawback programs may also benefit from consulting with a licensed broker who understands CBP enforcement priorities at the LA/Long Beach port complex.

For importers moving consumer products, electronics, machinery, or textiles through the Ports of Los Angeles or Long Beach, Michio Nakayama at Seishou Customs Brokerage in Lomita, CA represents a locally knowledgeable and professionally affiliated customs broker option in the South Bay area.
