Port volumes
In 2025 the port handled about 127 million tons of crude oil and 62 million tons of petroleum products, according to the port's reported figures.
Corpus Christi is a Texas Gulf Coast port described as the largest US gateway for crude oil exports. Refineries and Cheniere's LNG liquefaction terminal create Class I Division 1 and Zone 1 areas at process units, LNG trains, storage and ship loading. If you are specifying an industrial mobile phone for Corpus Christi, Texas, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Corpus Christi, Texas: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ingress protection | IP rating for dust and water | IP68 design |
| Fleet management | EMM and MDM support | Android 16 with EMM and MDM |
| Explosion protection | A separate certificate and marking | In progress; not issued |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Corpus Christi. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of the site and the kinds of classified area that matter for portable equipment.
In 2025 the port handled about 127 million tons of crude oil and 62 million tons of petroleum products, according to the port's reported figures.
Cheniere's Corpus Christi terminal produced first LNG from its Stage 3 expansion in December 2024, designed to add about 10 million tonnes a year.
The city has one of the highest average wind speeds of any coastal city in North America, which is why it is a wind-sports destination and why outdoor work is often wind-exposed.
Corpus Christi sits 130 miles southeast of San Antonio and 208 miles southwest of Houston, and about two thirds of its area is water, because the city boundary takes in Nueces Bay and Corpus Christi Bay.
Cheniere's Corpus Christi LNG plant has a net liquefaction capacity of 18 million tonnes a year and was reported receiving about 2.37 billion cubic feet of feed gas a day, close to its peak.
Road access is by Interstate 37, Interstate 69E and US 77, and State Highway 44 links the city west to Laredo; two main bridges, the New Harbor Bridge and the Kennedy Causeway, cross the bay.
“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.
The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.
In Corpus Christi, Texas. Port, refinery and LNG operations employ operators, ship crews and contractors in shifts, so MDM or EMM enrolment and controlled return of devices matter. Cheniere's Stage 3 expansion adds project crews. Operators often set their own IT policies, and charging should occur in offices or control rooms outside classified areas.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and still in progress.
Likely candidates are refinery process units, lng liquefaction trains, lng storage and loading, crude and product marine terminals. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
Yes, the city has some of the highest average wind speeds of North American coastal cities. Wind mainly affects ergonomics, lanyards and dropped equipment on elevated work, so a secure lanyard point and a case you can hold firmly with gloves are worth checking.
Freight normally comes through a larger Texas gateway and by road; San Antonio is 130 miles away and Houston 208 miles. Agree delivery windows with the site, since refineries and terminals often limit gate hours and require advance notice for vendors.
The port handles large volumes of crude oil and petroleum products, Cheniere's LNG terminal produced first LNG from its Stage 3 expansion in December 2024, and Valero, CITGO and Flint Hills each operate a refinery. Figures come from encyclopaedic sources. Confirm requirements with the site operator.
