About Nelson Calzadilla
Nelson Calzadilla is a CBP-licensed customs broker based in El Paso, Texas, with a career in customs brokerage dating back to 1995. Operating through TECMA Customs Solutions (merged with NCH Customs Brokers), he has served as President and brings deep expertise in US-Mexico cross-border trade, USMCA compliance, and the IMMEX maquiladora program. His El Paso location — one of the busiest land ports of entry in the United States — positions him to handle high-volume commercial imports and exports between the US and Mexico. With experience as both a compliance officer and operations director, Calzadilla offers importers hands-on knowledge of customs entry preparation, tariff classification, and regulatory requirements enforced by US Customs and Border Protection.
Nelson Calzadilla is one of El Paso's most experienced customs brokers, having held his CBP license since 1995. Based at 8700 Castner Ave., Suite B in El Paso, TX, he operates under the filer code E4G and has built his career around US-Mexico border trade — one of the most complex and high-volume trade corridors in the world. As founder and President of NCH Customs Brokers and, more recently, through the merger with TECMA Customs Solutions, LLC, Calzadilla brings institutional knowledge that spans decades of cross-border commerce.
El Paso sits directly across from Ciudad Juárez, Chihuahua, making it a critical gateway for manufacturing goods, automotive components, electronics, textiles, and industrial machinery moving between Mexico and the United States. Calzadilla's specialization in USMCA (the successor to NAFTA) means he can help importers determine country of origin, qualify goods for preferential duty treatment, and navigate certificate of origin requirements — all critical for companies sourcing from Mexican manufacturing operations.
His expertise in the IMMEX program (Mexico's maquiladora framework) is particularly valuable for US companies operating or sourcing from Mexican assembly and manufacturing plants. Proper IMMEX compliance requires careful coordination of temporary import documentation on the Mexican side and accurate CBP entry filing on the US side — an area where Calzadilla's combined compliance officer and operations director background proves essential.
For importers, Calzadilla's services address the full customs lifecycle: from HTS code classification and ACE portal filings to Importer Security Filing (ISF) for ocean shipments, customs bond requirements, and customs compliance audits. El Paso handles a large share of truck crossings, and Calzadilla's familiarity with land border procedures at ports like Ysleta, Bridge of the Americas, and Paso del Norte gives clients an operational edge.
Whether you are importing manufactured goods, consumer products, or industrial equipment from Mexico, working with a broker who understands the nuances of USMCA rules of origin, IMMEX maquiladora regulations, and CBP's ACE portal requirements is critical to avoiding delays, penalties, and duty overpayments. Nelson Calzadilla's three decades of experience in El Paso make him a well-regarded resource for businesses engaged in US-Mexico trade.
