The Arizona-Sonora Business Resource Guide, which features the manufacturing products and services available in the region, was unveiled at an event Wednesday morning.

Tucson Mayor Jonathan Rothschild and Pablo Gonzales, Union Pacific’s senior business manager for Mexico, spoke about the importance of strengthening relationships between both states and the economic impact of cross-border trade.

The guide is a project of the Arizona Daily Star and the Tucson Hispanic Chamber of Commerce.

“If we can show Arizona and Sonora as a region, we have the potential to be an economic powerhouse,” Rothschild told a gathering of about 170 people at the JW Marriott Tucson Starr Pass Resort & Spa, in an event co-sponsored by the Arizona Commerce Authority and Tucson Regional Economic Opportunities.

Rothschild called the guide the “best evidence” he’s seen so far of cooperation between the two states.

“With this project the world can now know ... with a click of a button what supplies are available for a manufacturer,” he said.

Rothschild said there are plans to offer air service from Tucson International Airport to Hermosillo. Two 30-seat planes from a company based in Los Mochis, Sinaloa, are in the process of undergoing inspections and by early summer could be offering direct flights between the two cities, he said.

Gonzales spoke about Union Pacific’s partnership with Mexico. Union Pacific is the only rail company to go through all six gateways between the U.S. and Mexico, he said.

Among those gateways, in 2013 Nogales was the fastest growing and saw “tremendous” growth in exported goods, he said.

“Contributing to that is growth in a lot of different segments like the automotive sector, metals and minerals and grains,” Gonzales said.

Union Pacific is investing aggressively in its gateways to ensure it continues to meet the export demands from Mexico and support its growth, he said.

“That investment also means we have a strong sales presence southbound,” he said.

The 68-page resource guide includes a directory of administrative, legal, logistics and manufacturing companies, economic data, and tips for expanding business between borders.

Companies profiled in the guide include the Ford manufacturing plant in Hermosillo, which employs 3,300 and exports more than 300,000 vehicles each year; Mayberry’s, a company that builds industrial ovens in Yuma; and Promain, an Hermosillo company that manufactures underground mining elevator shafts.

The Star, in partnership with the Tucson Hispanic Chamber of Commerce, will distribute the guides. The project is sponsored by the city of Tucson, city of Nogales, Ariz., city of Nogales, Sonora, Ernst & Young, Cushman & Wakefield/Picor, Pima County, Global Advantage, The Offshore Group and The University of Arizona Tech Park.
