SONGNAM CHUN

Songnam Chun holds an active CBP customs broker license and operates out of Bensenville, Illinois, a community situated immediately adjacent to O'Hare International Airport — one of the busiest air cargo gateways in the United States. With filer code AD3, this broker is listed on the official CBP permitted customs broker contact list and is authorized to transact customs business on behalf of importers across the country.

Bensenville's position within the O'Hare logistics ecosystem makes it a natural base for customs brokerage activity. Importers moving commercial shipments through O'Hare — whether electronics, consumer goods, textiles, machinery, or other manufactured products — rely on locally based licensed brokers to navigate CBP entry requirements efficiently. A broker operating in this corridor is routinely involved in customs entry preparation, HTS code classification using the 10-digit tariff code system, and ensuring accurate valuation to minimize duty exposure.

For importers establishing new supply chains, understanding importer of record requirements is a foundational step, and working with a licensed broker helps ensure compliance from the first shipment. Services typically associated with a broker in this market include ISF filing (also known as the ISF 10+2 or importer security filing), which must be submitted at least 24 hours before a vessel's departure for ocean shipments. While O'Hare is primarily an air cargo facility, many Chicago-area importers also move ocean freight through Great Lakes ports or route through East and West Coast gateways.

Customs bond management is another core area of brokerage practice. Whether an importer needs a single entry bond for a one-time shipment or a continuous customs bond to cover ongoing import activity, a licensed broker can help determine the appropriate bond type and work with surety providers. Import bond requirements are set by CBP and are mandatory for most formal entries.

Brokers in the Chicago market also encounter Type 86 entry filings for Section 321 de minimis shipments — a growing area as e-commerce and low-value commercial imports increase in volume. Importers with qualifying shipments under $800 may benefit from understanding how the de minimis threshold applies to their supply chain.

Duty drawback is another service area worth exploring for eligible importers. Companies that export goods after importing them may qualify for a duty drawback program, including unused merchandise drawback, which allows recovery of duties previously paid. A duty drawback broker with knowledge of CBP regulations can help identify eligible transactions and file the appropriate claims.
