The Houston Ship Channel links the Port of Houston to the Gulf of Mexico and is lined with refineries, chemical plants and terminals, forming one of the largest petrochemical complexes in the world. Houston has a humid subtropical climate, with highs of at least 90 degrees Fahrenheit on an average of 106.5 days a year and winds from the south and southeast carrying Gulf moisture. Distribution partners for Houston and the Houston Ship Channel are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Houston and the Houston Ship Channel 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.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. 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 Houston. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The companies on site and the hazardous-area types a handset is likely to meet there.
ExxonMobil's Baytown refinery (588,000 barrels a day, about 3,400 acres) sits beside the channel. The Deer Park refinery (about 275,000 barrels a day crude capacity) has been wholly owned by Pemex since Shell completed its exit in January 2022.
Houston has a humid subtropical climate with long hot summers and exposure to Gulf hurricanes and flooding, which shapes outdoor work and turnaround planning.
The Port of Houston is the busiest US port by overall tonnage and by foreign tonnage, and is run as a cooperative of the port authority and more than 150 private companies.
Houston sits on flat Gulf coastal plain, and the flat terrain together with extensive development has worsened flooding, which can affect low-lying sites and access roads in heavy rain.
The channel runs from the Turning Basin about four miles east of downtown Houston to a Gulf gateway between Galveston Island and the Bolivar Peninsula.
The modern port was approved by Harris County voters in 1909 and opened in November 1914, partly because an inland port was seen as safer after the 1900 Galveston hurricane.
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Houston and the Houston Ship Channel. Along the Houston Ship Channel, refineries, chemical plants and terminals each run their own contractor approvals, so a reviewer will want certificate evidence in a form they can file. A dual ATEX and IECEx route is designed to help international contractors and EPCs bring one documented basis to several operators. The IS-04Z1 certification is in progress; no certificate has been issued.
A distributor for Houston and the Houston Ship Channel 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.
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Likely candidates are refinery process units, petrochemical plants, tank farms, dock and terminal loading areas. 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 Houston and the Houston Ship Channel.
Houston typically sees highs of 90 degrees Fahrenheit or more on over 100 days a year, with high humidity from the Gulf. Check a handset's stated operating range and humidity rating on its datasheet, and avoid leaving devices in closed vehicles.
The channel is lined with refineries and chemical plants, with major private complexes at Baytown and Deer Park and public terminals at the Turning Basin, Barbours Cut and Bayport. Always confirm which operator controls the specific gate you are visiting.
No. The IS-04Z1 is pre-launch and certification is in progress, so no certificate exists. Each refinery and chemical operator along the channel sets its own contractor and equipment approvals. A buyer can evaluate the datasheet and a safe-area use now, and should confirm requirements with the site operator.
