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. Distribution partners for Corpus Christi, Texas are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Corpus Christi, Texas has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
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.

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.
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Corpus Christi, Texas. LNG liquefaction and crude export involve international EPCs, vessel crews and inspectors, many familiar with IECEx documents. The aim is a certificate of conformity and a schedule of conditions that an engineer can read against a specific area. It remains in progress, and operators decide what they accept.
A distributor for Corpus Christi, Texas would carry the IS-04Z1 after certification completes; the Q4 2026 launch is the planning date and no appointment has been made. SAMS reviews applicants one by one and prefers companies with their own Ex-competent technical and service staff, since certified devices must not be repaired outside approved channels.
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.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Corpus Christi, Texas.
LNG sites combine cryogenic storage, vaporising gas and compressor stations, so gas-hazard zones typically surround tanks, loading areas and compressor buildings. Which parts are classified is defined by the operator's drawings, and you should confirm before taking any phone into a plant.
June to September is the hottest period, with a record high of 109 degrees Fahrenheit, so check that a handset's stated operating and charging temperature range covers that, and avoid leaving devices in vehicles. Confirm the figures on the datasheet rather than assuming.
Not necessarily. LNG trains, storage and ship loading handle different substances and layouts from refinery process units, so each operator classifies its areas separately. Ask each operator which locations are classified, whether Division or Zone terms are used and what equipment evidence it accepts.
