About Martin E. Tamez
Martin E. Tamez is a licensed U.S. customs broker based in Laredo, Texas, operating under CBP filer code B4B. Laredo is the largest inland port of entry in the United States, handling an enormous volume of cross-border trade between the U.S. and Mexico. A broker operating out of this market brings direct, on-the-ground experience with the documentation requirements, CBP procedures, and logistical realities that define high-volume land border clearance. Importers moving goods through the Laredo port of entry — whether by truck, rail, or other commercial modes — benefit from working with a local broker who understands the specific demands of the US-Mexico trade corridor, including USMCA origin requirements, commercial invoicing standards, and timely customs entry preparation.
Martin E. Tamez holds an active CBP customs broker license and operates out of Laredo, Texas, one of the most strategically significant ports of entry in the entire U.S. customs system. Laredo consistently ranks as the top U.S. land port by trade value, processing hundreds of billions of dollars in cross-border commerce annually — the vast majority involving imports and exports between the United States and Mexico. For importers who regularly ship through this corridor, having a licensed broker with local presence is not a convenience; it is a practical necessity.
As a licensed customs broker, Martin E. Tamez is authorized to transact business with U.S. Customs and Border Protection (CBP) on behalf of importers, covering the full range of entry types processed at the Laredo port of entry. This includes customs entry preparation and filing through the ACE portal, coordination of Importer Security Filing (ISF) requirements for applicable shipments, HTS code classification to ensure correct duty assessment, and management of continuous customs bond obligations that keep commercial import programs running without interruption.
The Laredo trade corridor is dominated by manufacturing-related imports moving northward under USMCA — automotive parts, electronics, machinery and equipment, consumer goods, textiles and apparel, chemicals, food and beverage products, and steel and metals all move through this port in significant volumes. Importers sourcing from Mexican manufacturers, operating maquiladora supply chains, or managing near-shoring programs benefit directly from a broker who understands the local classification and admissibility requirements that apply to these commodity lanes.
Beyond routine clearance, a Laredo-based broker handles the real-world complexity of border trade: responding to CBP examinations, resolving holds, managing documentation discrepancies, and working within the compressed timelines that truck-based imports demand. US import requirements for land border entries differ in important operational ways from ocean or air freight, and local knowledge of CBP Laredo's processes can make a material difference in clearance times.
Importers evaluating Martin E. Tamez for their U.S.-Mexico import operations should consider the value of direct access to a licensed professional at the port level, with familiarity in customs compliance audit exposure, duty drawback opportunities, and the practical mechanics of keeping cross-border supply chains moving efficiently.
