The port handles roughly 28 per cent of Brazil's total cargo, so terminals run continuously.
The Port of Santos in Sao Paulo state is Latin America's largest port and handled a record 186.4 million tonnes in 2025. Hazardous areas arise at liquid-bulk terminals handling fuels, chemicals and vegetable oils, and at tank farms and tanker berths. This page explains what to look for in an intrinsically safe mobile phone for Port of Santos, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Port of Santos: 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. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Santos Port Operations. 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.
The port handles roughly 28 per cent of Brazil's total cargo, so terminals run continuously.
Alemoa alone has four ship piers and about 112 tanks used by Transpetro and other companies, each with its own procedures.
The Santos Port Authority has begun installing a private 5G network under its Porto de Santos Conecta programme, relevant to anyone planning radio or data devices on the quay.
Exports of gasoline rose 24.1 percent and fuel oil 15.3 percent in August 2025 alongside pulp and soybeans, showing steady liquid-bulk flows through the port.
The port accounted for 29.9 percent of Brazil's total trade flows in August 2025 and recorded 489 ship calls in the month, up 9.6 percent.
It has terminals for solid and liquid bulk, containers and general cargo, and land access is by the Anchieta and Imigrantes highways and by railways run by Ferroban and MRS.
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Port of Santos. Terminals run continuously and the port handles roughly 28 per cent of Brazil's total cargo, so rounds across piers, tank farms and loading arms never stop. An intrinsically safe handheld suits those rounds and cargo inspections. The IS-04Z1 is designed for them, subject to certification.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
Likely candidates are liquid-bulk fuel and chemical terminals, tank farms, tanker piers and loading arms, lpg handling. 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.
Operations run at high volume with many ship calls a month, and gate or terminal inductions are usual. Confirm with the terminal which devices are allowed in classified areas, and whether certificates and personal protective equipment checks apply.
Possibly, for terminals that connect to it. Compatibility and access rules depend on the port authority and each terminal operator, so confirm which radio bands, SIM or network access and device approvals are accepted.
The sheet notes that its Alemoa terminal operator list comes from a port directory and may be dated. Verify current operators directly. Confirm with the site operator who runs which pier or tank before assuming a particular policy applies.
