Nogales port of entry guide

Nogales Location

Nogales lies at about 31 degrees 20 minutes north and 110 degrees 56 minutes west, in Santa Cruz County, Arizona, hard against the US-Mexico border. The city sits in the upper Santa Cruz River valley at about 1,200 meters elevation, about 65 miles north of Tucson. The location's trait is a single corridor: northbound land traffic from Mexico enters mainly via the I-19 corridor.

• State: Arizona, in the US Southwest, bordering Utah north, New Mexico east, California and Nevada west, Sonora, Mexico south
• Crossing location: City of Nogales, Santa Cruz County; the city and Nogales, Sonora form a cross-border twin-city structure
• Main highways: I-19 north-south (to Tucson, Phoenix); AZ-189 the main road for commercial trucks to the crossing; AZ-82 links state agricultural areas
• Rail: Union Pacific serves the port; Mexico side connects via the Ferromex network
• Airport: Nogales International Airport under the port (by appointment); Tucson International about 70 miles north
• Corridor role: US southern gateway of the CANAMEX corridor, linking western Canada, the US West and Mexico's Pacific coast and Mexico City
• Market distances: Tucson about 70 miles, Phoenix about 170 miles, Guaymas deepwater port Mexico about 241 miles, El Paso about 340 miles

The three modules that matter for China export are one concentrated commercial crossing, a cold-chain and distribution belt clustered at Rio Rico and the industrial park to the west, and the road and rail links through Tucson and Phoenix. They sit within tens of miles, so pickup and delivery timing is relatively controllable. The overall distribution of Southwest US entry points is in the US ports overview section.

Nogales Port of Entry Overview

In the US customs system Nogales is a land border port, code 2604, registered as Nogales, Arizona. It is a service port with full cargo functions: exam, entry filing, collection and verification. The supervising field office is in Tucson.

One trait is desks split by commodity group. The two import specialist groups differ: group 641 covers plastics, leather, textile and footwear, electronics, machinery, precious metals, toys, art and arms; group 650 covers live animals, food, minerals, chemicals, wood and paper, stone and glass, base metals, vehicles, aircraft and vessels. Confirming the right group before sending usually saves one transfer. General rules on commodity admission and tariff are in the US customs import and export policy section and the US customs import and export tariff section.

Crossing Facilities and Channels

The port has three channels and one airport. Commercial freight concentrates at one crossing, passengers and pedestrians use the other two, so trucks and personal vehicles do not queue at the same entrance.

Commercial flow at one crossing is what sets this port apart from most multi-bridge border ports. Concentration brings two results: exam resources and inspection equipment sit at one site, giving strong fresh and refrigerated handling capacity; and trucks can only use one main road, so peak-season queues concentrate at one entrance. The Mariposa crossing completed about USD 250 million of upgrades from 2009 to 2014, mainly to add lanes and exam capacity. About 85 percent of US-Mexico commercial trucks now enter here.

Commercial Freight Hours

Freight hours shift by season. In winter (usually from mid-to-late October) the truck crossing closes later to match the fresh produce peak. The table shows commonly published hours with the winter notice as reference.

Note that the port's main table and the seasonal notice do not fully agree on Saturday hours, so the current port notice governs. The practical advice for shippers is to schedule northbound crossing in the early morning, when both exam staffing is fullest and road traffic is lightest. Southbound export and bonded moves have separate hours; Mexico-side in-bond business must be confirmed separately and not by the northbound schedule.

Unified Cargo Processing and FAST

The port has a distinctive exam arrangement: US and Mexican customs jointly examine the same shipment at one site. This started at Nogales to cut double queuing on both sides.

For importers the meaning is: with a stable supply chain and clean filing, C-TPAT certification opens the fast lane and clearly shortens crossing time; with scattered sources and frequent carrier changes, meeting the three-party condition is hard. Certification itself takes a cycle and internal process work, a medium-term arrangement rather than a temporary clearance trick.

Rail Conditions

Rail is what separates this port from pure-road border crossings. Union Pacific serves the port and states coverage of all six major US-Mexico crossings; the Mexico side connects via the Ferromex network, meeting at Nogales.

Rail matters at both ends: southbound it carries Mexican factory finished goods and produce north; northbound it links southern Arizona to West Coast ports and Midwest hubs. Local produce interests are also exploring rail outbound from Nogales to the US East and Midwest as an alternative to long-haul trucking. Rail has less time flexibility than truck but usually lower unit cost, suiting steady volume with non-extreme time needs.

Road Conditions

Road access runs on the I-19 corridor as the main axis. Northbound the port has only this one main channel, and traffic queues at the crossing and city streets before reaching the interstate, which directly sets dispatch timing.

• I-19: north-south arterial, Nogales to Tucson about 65 miles, then north to I-10 toward Phoenix and beyond.
• AZ-189 (Mariposa Road): main road for commercial trucks to the Mariposa crossing, linking state route 189.
• AZ-82: east-west, linking state agricultural areas.
• Southbound link: Mexico federal highway 15D, south to Sonora industrial areas and Mexico highway 15.
• Corridor role: US southern end of the CANAMEX corridor; an 8-hour road radius covers Phoenix, Tucson, Las Vegas and Southern California, a 16-hour radius Salt Lake City, Denver, Houston and Dallas.
• Overweight permit: the Arizona Department of Transportation can issue overweight permits on designated routes, allowing up to 90,800 pounds within a northern range, 10,800 pounds above the 80,000-pound general limit, on the prescribed route.

The overweight permit has real meaning here. Arizona allows weights above the general limit on designated routes, important for produce because a full box of fruits and vegetables is heavy and often cannot fill under the general limit. The permit is route-specific; portions outside it do not apply, so confirm the permit range for the destination when loading.

Produce Cold-Chain Facilities

Produce is the port's most prominent category. Nogales ranks among the top US ports for Mexico produce tonnage, with about 120,000 produce trucks and some USD 2.5 billion of value entering the United States each year.

Facilities within a few square miles is a condition of this port: after crossing, goods are usually received, examined, sorted, labeled and reloaded within hours, then moved north by reefer truck. The model also fits non-produce: use Nogales as the first break-bulk point after entry, then do value-added work or transfer to a domestic line-haul vehicle. Local cold storage is tight, so book space ahead in peak season; walk-in space is scarce.

Warehouse and Distribution

A belt of mostly cold-chain, partly general warehouse has formed around the port. Beyond produce, these facilities also take consumer electronics, medical devices, auto parts and industrial goods.

Versus the warehouse belts around West Coast ports, land and rent here are lower, but individual facilities are smaller and cold storage is tight. The common pattern is: first devanning and distribution near a West Coast port, then move the cold-chain or further-processed part to Nogales. Conversely, if the consignee is in Arizona, New Mexico or northern Mexico, using this port as the entry point is usually simpler.

Foreign-Trade Zone 60

The port's tariff arrangement sits in Foreign-Trade Zone 60, covering all of Santa Cruz County, grantee the Nogales-Santa Cruz County Economic Development Foundation. The zone hosts industrial and light-manufacturing projects.

The zone's positioning ties to the cross-border processing chain. Mexican-side factories make finished or semi-finished goods that, on entering the United States, can be staged, inspected or lightly processed in the zone before deciding domestic sale or re-export. Core benefits are duty deferral and re-export exemption; where the imported-component rate exceeds the finished-product rate, domestic sale can use the finished-product rate, subject to prior authorization. Related information is in the US customs information section.

Two-Way Cross-Border Flow

Nogales flow is two-way. Northbound is mainly finished goods and produce; southbound mainly raw materials, parts and packaging. This structure makes in-out traffic more balanced than pure-import ports.

The two sides form a twin-city structure, Arizona Nogales on the north and Sonora Nogales on the south, with maquiladora manufacturing dominant. For China exporters the direct meaning is that this port is not only an entry point but a gateway into northwest Mexico's manufacturing hinterland; conversely, southbound business (e.g. sending China-made parts to a Mexican factory, or packaging materials for local re-export) uses the same process. Per the local development foundation, the produce sector's direct economic impact exceeds USD 30.3 million and 2,500 jobs, rising to 4,000 jobs and USD 437.7 million with indirect and induced effects; maquiladora-related direct impact exceeds USD 20.68 million and 1,000 jobs, rising to 1,500 jobs and USD 304.9 million with indirect and induced effects.

Routing from China to Nogales

China cargo to Nogales has two basic routes: discharge at a US West Coast port then road or rail into southern Arizona; or discharge at a Mexico Pacific Coast port, move north by Mexico road, then enter at this port.

To note: if the consignee is in the United States, the West Coast port route is more direct; routing via a Mexico port suits consignees actually in Mexico or business needing local processing. Using Mexico only as a transit channel adds Mexico-side entry and bonded transport steps, making the process longer than direct US entry.

Transit Times from China

The ranges below are the common overlap of several forwarders' published transit tables. Ocean leg counts from China port loading; road and rail count from West Coast port discharge; both exclude cut-off and clearance.

Three variables hit actual time: the fresh-produce peak (winter and spring) concentrates crossing queues; Southwest US summer heat limits road hours, some carriers shift to night driving; and winter snow in Arizona mountains can restrict I-19 and I-10 locally. If delivery falls in the produce peak, add three to five days of buffer beyond the sailing schedule.

Pickup and Delivery After Arrival

This port's pickup flow differs from a seaport: cargo is not picked up at a terminal yard but, after crossing, enters a local warehouse or yard where the parties hand over at the agreed point. This difference sets the order of document and dispatch preparation.

1. After discharge at a West Coast port, the carrier moves goods to southern Arizona by agreed mode, or directly to a warehouse near the crossing.
2. The broker completes the import filing and gets release, or processes in-bond transfer.
3. The vehicle crosses in the port's published freight window and is examined or released at the Mariposa freight facility.
4. Goods reach the local warehouse or yard and are received, counted and sorted per agreement.
5. Reefer cargo completes pre-cooling and temperature-record handoff in cold storage.
6. Reload onto a domestic line-haul vehicle per consignee, or transfer to a rail yard.
7. Empties and chassis return to the carrier-designated point; reefer equipment follows cold-chain rules.

Three common delay causes: treating the port like a seaport pickup point and dispatching to the wrong place; not booking cold storage ahead so arrival has nowhere to go in peak; and not confirming reefer temperature records and power at handoff, making later quality disputes hard to trace. The third is common in produce; list the temperature record separately on each shipment's handoff sheet.

Customs Exams and Release

Exams are decided by CBP and relate to filing compliance, import record and commodity. Exam resources concentrate at the Mariposa site, with strong fresh and refrigerated handling capacity.

Produce exams here focus on plant quarantine and food safety, mostly at one site, cutting multi-location trips but meaning a pick can clash with produce time pressure. The practical move is full product data and quarantine certificates in advance, and arrival in the morning to leave same-day time for possible exam.

Operating Hours and Holidays

Port hours and local warehouse hours must be read separately. The freight crossing extends in winter; warehouse and cold-storage receiving follow their own schedules, not fully overlapping.

Avoid federal holidays, Mexico holidays and year-end holidays. There are 11 US federal legal holidays in total, listed in the US holidays overview section. Mexico-side legal holidays also move this port's traffic; when both sides close together, flow drops sharply but cross-border arrangements tighten too. Year-end specifics are usually announced by the field office ahead, e.g. Thanksgiving market closed but rail runs, Christmas Day and New Year's Day rail also closed. For year-end delivery, confirm the current window with the carrier in advance.

Peak and Off-Peak Seasons

The port's volume rhythm overlays two lines: Mexico produce season, and manufacturing production and replenishment. The former is clearly seasonal, the latter relatively steady.

Three local variables to forecast: produce-peak crossing queues and tight cold storage; summer heat limits on road hours; and winter Arizona mountain snow affecting I-19 and I-10. Book space days ahead in peak season and buffer the plan. Related ocean and air options are in the China-US freight section.

Logistics Advantages

• Commercial flow at one crossing: all commercial trucks enter via Mariposa, with exam resources and inspection equipment at one site; the crossing's about USD 250 million upgrade from 2009 to 2014 added lanes and exam capacity. Trucks need not choose among multiple entrances, simplifying dispatch.
• Concentrated cold chain and distribution: over 100 cold-chain and distribution facilities near the port, over 85 produce distributors, mostly at Rio Rico and the industrial park within miles of the crossing. After crossing, goods are usually received, examined, sorted, labeled and reloaded within hours.
• Joint US-Mexico customs exam: this port first ran Unified Cargo Processing, US and Mexican customs examining the same shipment at one site; CBP reports over three hours saved per exam. A FAST lane at Mariposa serves the three C-TPAT-certified parties (carrier, importer, driver).
• Direct link to northwest Mexico manufacturing: the port and Sonora Nogales form a twin city, the maquiladora system making a cross-border production chain; northbound finished goods and produce and southbound materials and parts balance the flow, with Union Pacific and Ferromex meeting at both ends.

Three points to watch: the port has only I-19 northbound, so peak queues concentrate at one entrance; local cold storage is tight and facilities small, so book ahead in peak; and the crossing hours shift with winter time and the Saturday item differs between the main table and the seasonal notice, so confirm the current port notice before planning.

The main table and seasonal notice differ on Saturday, so confirm the current port notice before planning.

How long from China to Nogales?

The main route discharges at a US West Coast port then moves to southern Arizona. Ocean leg about 12 to 18 days, West Coast to southern Arizona road about 1 to 3 days, rail to Tucson about 2 to 4 days, door to door commonly 18 to 28 days. Via a Mexico Pacific Coast port, the ocean leg is about 20 to 28 days plus Mexico in-country road time.

What is Nogales' produce scale?

Nogales ranks among the top US ports for Mexico produce tonnage. About 120,000 produce trucks and some USD 2.5 billion of value enter each year, 300 to 500 per day at peak. Main commodities are tomatoes, cucumbers, peppers, squash and melons, watermelon, mango and grapes. Over 100 cold-chain and distribution facilities and over 85 produce distributors cluster near the port.

What is Unified Cargo Processing?

Unified Cargo Processing is the joint US-Mexico customs exam of the same shipment at one site, first run at Nogales. The US requires a C-TPAT-certified carrier, and CBP reports over three hours saved per exam. Mariposa also has a FAST dedicated lane for low-risk cargo where carrier, importer and driver all hold the relevant certification or enrollment.

Is there a foreign-trade zone locally?

Yes. Foreign-Trade Zone 60 covers all of Santa Cruz County, grantee the Nogales-Santa Cruz County Economic Development Foundation, registered at 825 N. Grand Avenue, Suite 200, Nogales, AZ 85621. The representative project is North America Trade Center, about 43 acres and about 700,000 square feet, about 2 miles from Mariposa. Main benefits are duty deferral and re-export exemption. Related information is in the US customs information section.

What are the rail conditions?

Union Pacific serves the port and states coverage of all six major US-Mexico crossings; the Mexico side connects via Ferromex, meeting at Nogales. The port rail exam gate runs daily 08:00 to 17:00. Northbound it links Tucson, Phoenix and Midwest hubs via Union Pacific.

What permits does overweight transport need?

The Arizona Department of Transportation can issue overweight permits on designated routes, allowing up to 90,800 pounds within a northern range, 10,800 pounds above the 80,000-pound general limit. The permit is route-specific and the vehicle must stay on the prescribed route; portions outside it do not apply. Permit fees are shared by state and local for maintenance of affected local roads.

What to watch at pickup and delivery?

Three points. First, this is not a seaport pickup point; goods enter a local warehouse or yard after crossing, so confirm the dispatch location at booking. Second, local cold storage is tight, book space days ahead in peak. Third, list reefer temperature records and power arrangements separately at each handoff for later tracing. Schedule crossing in early morning.

Which cargo suits Nogales?

Three types fit well: food and produce needing cold chain; cargo with consignees in Arizona, New Mexico or northwest Mexico; and parts and finished goods needing Mexico-side processing before entering the United States. If the consignee is on the US West Coast or Midwest, direct entry via a West Coast port is usually more direct.
