With direct access to major rail yards, trucking networks, and air cargo facilities, Moon So can assist importers with customs entry preparation, HTS code classification, and compliance with US import requirements across a range of commodity types.

Moon So is a federally licensed US customs broker holding CBP filer code N30, with an office in Palatine, Illinois — a northwest suburb of Chicago situated within close proximity to O'Hare International Airport (ORD). This geographic positioning makes Moon So a practical choice for importers routing air freight or consolidated cargo through one of the country's busiest cargo airports, as well as for those managing inland shipments via Chicago's extensive rail and trucking infrastructure.
For importers navigating US import requirements, working with a licensed broker like Moon So means having a qualified professional handle the regulatory and administrative complexity of customs clearance. This includes customs entry preparation, proper HTS code classification using the USITC tariff database, and submission of entries through the CBP ACE portal. Accurate HTS code classification — whether for clothing, electronics, machinery, or other goods — is foundational to calculating correct duty rates and avoiding costly delays or customs compliance issues.
Moon So can assist with Importer Security Filing (ISF), which is required for ocean freight shipments at least 24 hours before vessel departure. ISF filing errors are a common source of CBP penalties, making experienced broker support particularly valuable. For importers holding continuous customs bond coverage or evaluating customs bond requirements for the first time, Moon So can help determine the appropriate bond type and value based on shipment volume and entry frequency.
The Chicago area serves as a major distribution point for goods originating from Asia, Europe, and beyond. Importers dealing with CBP entry types — from formal consumption entries to section 321 de minimis shipments — benefit from a broker who understands the nuances of each classification and the documentation each requires. Moon So is also positioned to assist clients navigating partner government agency customs requirements, including FDA, USDA, and other agency reviews that apply to regulated product categories.
For businesses exploring duty drawback programs or seeking to recover duties paid on exported goods, a licensed broker can help identify eligible shipments and prepare duty drawback claims. Moon So serves individual importers, small businesses, and mid-sized companies in Illinois and throughout the Midwest that need licensed, professional customs brokerage support.
