From a farm or a maquila in Sonora, Mexico, to a supermarket in Chicago, the journey of products coming from Mexico is a long, sometimes slow one. But according to border experts and officials, it’s during customs inspections at the border that the process gets delayed the most because ports of entry are understaffed and their need for investment is often overlooked.

According to a 2016 Customs and Border Protection report to Congress, CBP has 2,107 unfilled officer positions, despite an increase of more than 30 percent in trucks with goods crossing from Mexico over the last decade, according to data from the Bureau of Transportation Statistics.

In Arizona, the Tucson sector had over 20 percent of unfilled positions, according to a letter the Arizona Border Counties Coalition sent to the state’s congressional delegation in August.

“(Ports of entry) have been significantly neglected by both the U.S. and Mexican federal governments. This is one of those things that’s almost too big to see,” said Erik Lee, executive director of the North American Research Partnership, which is based in Arizona.

The lack of staff and investment in technology and modernization of the ports of entry has led to longer waiting times during crossings, which ultimately hurts businesses and tourism, according to Lee and the Nogales-based Fresh Produce Association of the Americas.

“You get a depressed shopping environment in local border communities, and on the commercial side, you have these long border wait times (that) potentially hurt transportation, manufacturing and agricultural companies,” Lee said.

Lance Jungmeyer, president of the Fresh Produce Association of the Americas, said ports of entry need more agricultural inspectors, but they are usually not the priority for hiring and investment efforts.

“The agriculture specialists are a huge part of the puzzle,” Jungmeyer said. “The staffing need for this area has been ignored, while border patrol has been staffed up.”

According to CBP’s report, 631 agriculture specialists are needed nationally.

Jungmeyer said certain fruits and vegetables, particularly those with many leaves or places where bugs can hide, require a lot of time of inspection.

“What happens is, the trucks that need to be inspected just stack up and they’re waiting there longer,” Jungmeyer said.

The longer the wait, the less fresh the produce is, particularly during the summer, according to Jungmeyer.

“When we’re not able to get the produce across in order to match up with the customer expectations, that’s a problem that certainly disadvantages us,” he said.

During peak season, from February to April, approximately 1,800 trucks cross through Nogales a day, Jungmeyer said.

Customs and Border Protection in Tucson did not respond to several requests for comment about the staffing and investment needs at their ports of entry.

However, according to the letter written by the Arizona Border Counties Coalition –which was signed by Cochise County Supervisor Patrick Call, Pima County Supervisor Sharon Bronson, Santa Cruz County Supervisor Bruce Bracker and Yuma County Supervisor Tony Reyes – “the need for infrastructure improvements and additional CBP staffing at the ports of entry are critical concerns.”

It says the DeConcini Port of Entry “needs modernization to facilitate the growing volume of daily crossings,” the Douglas Port of Entry is “in desperate need of investment” and the San Luis I Port of Entry “has not had significant investments in over 30 years.”

Rep. Raul Grijalva, D-Tucson, said in a written statement to Cronkite News: “Updating and modernizing our infrastructure at ports of entry is a necessary investment not only for our state but also for the millions of constituents who benefit from it. To continue to militarize our border by focusing solely on enforcement mechanisms is a great disservice.”

But lack of investment is not the only challenge the Arizona ports of entry face.

Experts say it’s difficult to hire for CBP officer positions because the border is not very attractive to potential workers, and the process of getting hired takes about a year.

“A lot of these folks are married and their spouses want to work, and they have a very difficult time finding jobs in these small communities,” Lee said.

Teresa Bravo, economic development and international projects coordinator at Pima County, said she met with several CBP officials from Washington who told her “they’re having a really hard time recruiting.”

“They’re trying to work on a marketing plan to kind of sell the state better and say, ‘There’s actually all these things happening,’” Bravo said.

“It is a hard job,” Lee said. “It has long periods of boredom punctuated by a lot of excitement, that’s very stressful. It’s a difficult job, no matter how you look at it.”

But Lee thinks there are not so expensive solutions that can be put in place without the need for large investments.

According to Lee, improving “trusted traveler and shipper programs,” which pre-approve eligible “low-risk” travelers through background checks, could help mitigate some of the logistics problems.

Still, both Lee and Jungmeyer believe Congress needs to know more about the importance of the role that ports of entry play in border security, shifting from the almost exclusive focus they give to border patrol.

“It’s just a matter of educating Congress,” Jungmeyer said. “When you talk about border security, trade, you also have these subset of officers that are very important.”

“Kind of a feel of the border in the national capital is that it is not altogether positive,” Lee said. “Both countries have thought of it mostly as a security concern, rather than as a trade and an economic development opportunity, which it also is.”
