Ex-Proof Mobile Phone in Manaus Industrial Zone
Suframa describes the Manaus Industrial Pole as about 600 high-tech industries in electronics, IT goods, two-wheelers, naval, mechanical, metallurgical and thermoplastics, with 2025 revenue of R$227.67 billion and over half a million jobs. Hazardous areas arise mainly at the Ream refinery site and fuel handling rather than in the factories; the refinery has reportedly stopped refining crude since early 2025. If you are specifying an Ex-proof mobile phone for Manaus Free Trade Zone, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

What Manaus Free Trade Zone means for portable equipment
River and air logistics
Manaus is served by the Negro and Amazon rivers and by an international airport, with limited road links, so deliveries from the south-east take longer.

More about Manaus Free Trade Zone that matters for portable equipment
Manaus Free Trade Zone: climate and equipment wear
Manaus has a tropical monsoon climate with an average temperature of 27.4 degrees Celsius, high air humidity and about 2,300 mm of rain a year, so enclosures and seals face constant moisture.
Manaus Free Trade Zone: logistics and access
Aerial photography of the Isaac Sabba refinery shows it on the Negro River in the Amazon forest with oil tankers alongside, reflecting river-borne supply of crude and products.
Manaus Free Trade Zone: rules and approvals
Decree-Law 288 of 28 February 1967 redefined the zone with an area of 10,000 km2, including industrial and agricultural centres, as a vehicle for regional development in the Amazon.
Manaus Free Trade Zone: infrastructure

The term · Ex-proof
What “Ex-proof” means for a smartphone
“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 Manaus Free Trade Zone. A marking check in Manaus is narrower than in a refinery city, because only fuel and chemical handling points are classified. Zone suitability, gas group and temperature class should be compared with the operator's classification. The IS-04Z1 target marking II 2 G Ex ib IIC T4 is not yet certified.

Questions · Manaus Industrial Zone
Frequently asked questions
Can we buy an Ex-proof mobile phone in Manaus Industrial Zone today?
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
What does an Ex-proof mobile phone in Manaus Industrial Zone cost?
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.
What Ex marking will the IS-04Z1 carry?
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.
Which areas at Manaus Free Trade Zone would use it?
Likely candidates are fuel storage and loading, refinery and fuel logistics, port petroleum and chemical handling. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
Is intrinsically safe the same as explosion proof?
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.
What hazardous areas exist in the Manaus Industrial Zone?
Mostly fuel handling: the refinery, tank and terminal areas and product loading, plus solvent, paint and battery processes in some factories. Zones are set by each site's classification study, so ask the plant safety team which areas need certified mobile devices.
Do Manaus factories need Ex-rated phones?
Only where flammable gases, vapours or dusts can occur, such as fuel storage, solvent and coating areas. Many electronics assembly halls are non-hazardous, so check the plant's area classification before buying certified devices for every user.
Why does delivery take longer to Manaus?
Manaus is served by the Negro and Amazon rivers and an international airport, with limited road links, so deliveries from the south-east take longer. Plan lead times and spares accordingly, and confirm delivery routes with the supplier or distributor concerned once certification is complete.
