Large chemical cluster
The Ankleshwar Industries Association lists 220 chemical, 156 dye and dye intermediate, 11 pesticide and 69 pharmaceutical member units, among others.
Ankleshwar, in Bharuch district, Gujarat, hosts a large GIDC industrial estate and chemical cluster of about 1,600 hectares. Sources report between 1,500 and 2,000 units making chemicals, dyes, pesticides and pharmaceuticals, where solvent handling creates classified areas. An Ex-proof mobile phone distributor in Ankleshwar would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Ankleshwar 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. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

Ankleshwar is about 14 km from Bharuch city, on the Mumbai-Delhi national highway and the Western Railway line.
The state development corporation runs chemical estates at Vapi, Ankleshwar, Panoli, Nandesari and Naroda, and managed 257 estates across Gujarat as of 2008.
Heavy monsoon rain often brings flooding to the Narmada basin, with major floods most recently in 2023, although the damming of the river has largely controlled it.
The Ankleshwar Industrial Association, part of the Gujarat Industrial Development Corporation estate, has over 2,000 industries registered, so a single estate holds a very large number of separate operators.
Ankleshwar is a hub of the Indian chemical industry, and its industrial estate produces more than 5 percent of the country's chemical output, including pharmaceuticals and dyes.
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Ankleshwar. A marking check should compare the gas group and temperature class with each plant's solvent data. Solvents vary in properties, so one unit may need a different group from another. The IS-04Z1 targets II 2 G Ex ib IIC T4, subject to certification, and the plant decides whether it suits each area.
A distributor for Ankleshwar 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.
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Likely candidates are chemical reactors and solvent areas, dye and dye intermediate plants, pesticide manufacturing, pharmaceutical bulk drug solvent handling. 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 Ankleshwar.
An estate has thousands of small and medium units run by different companies, each with its own processes, solvents and safety rules. Hazardous-area requirements therefore vary unit by unit, so always ask each plant for its area classification and accepted approvals.
Ankleshwar is on National Highway 8 and the Western Railway, about 14 kilometres from Bharuch, with the nearest major airports at Surat, Vadodara and Ahmedabad. Agree access and gate times with each unit before sending staff.
The Petroleum and Explosives Safety Organisation is listed for hazardous-area matters, and the Gujarat Pollution Control Board regulates industrial pollution, which can add compliance requirements. The exact remit for a phone has not been confirmed here. Ask the plant operator which authority and documents apply.
