For importers navigating the complexity of U.S. Customs clearance, Michael S. Dubin CHB covers every stage of the process. This includes customs entry preparation, importer security filing (ISF) to meet ISF filing requirements ahead of vessel departure, HTS code classification using the USITC tariff database, and filing through the CBP ACE portal. Whether you're clearing a container of consumer goods arriving through Port Tampa Bay or an air freight shipment coming through a major gateway, the firm has the multimodal experience to manage each clearance accurately and on time.
The firm's freight forwarding capabilities span air freight, ocean freight, and cross-border trucking — a combination that reflects the diverse trade lanes accessible from Florida's Gulf Coast. Tampa's port connects importers to Latin America, Europe, and Asia, and Dubin's brokerage services are structured to support that geographic range. Importers sourcing from China and other Asian suppliers will find the firm's customs entry services and ACE portal experience particularly relevant, given the volume of trans-Pacific shipments that route through Florida's ports.
Beyond transaction-level clearance, Michael S. Dubin CHB provides consulting services that help importers stay ahead of evolving compliance obligations.
