Iran gas market divides to 3 layers,

۱-this layer is built less than 10 company that have 80% of Iran gas market and they supply most of the industrial and specialty gases.

These 10 companies are main gas distributors which have a good share in Iran gas market. their turnover is about 25.000.000$ per year for high purities gases .

۲-second layer  include intermediate companies that are a number about 70 companies which have 10% share of gas market and they have the turnover of about 2.500.000$ per year most of them work as a distributors an manufactures.

۳- in third layer we have more than 1000 companies that most of them are very small distributors.

SWOT analyses of gas industrial. :

۱- weakness

A – Iranian companies cannot produce high purities gases and hydrocarbons and most of the mixtures .

B – most of them can not produce specially equipment like low flow regulators , Iso tank , valves and cryogenic tank ….

C – due to the sanction, foreign suppliers are very limited

۲- strength

A – we have various industries in Iran that most of them use gas and can be our customers .

B – Iranian customers have a good knowledge regarding to technical point of which they use. they can easily separate high and low quality goods.

C-We have about 70 petrochemicals and refineries that use ultra high pure gases and especial mixtures up to 20 components .

D- Iranian companies use various kinds of special gases like :Ne, Kr, Si , Xe , SF6 , C1 – C10 , H2S , HCL , F2,CF4,NO , and etc .


A.New sanction by USA

  1. Importing rules are changing day by day in Iran.


A.There is not any famous gas companies in Iran any more , all of them left with starting sanction like Air products , Technical gas services , Lindee and so on .

If a company can supply customers with suitable price and high quality products , would be the winner and can be a famous brand within shortest time .

B.There are a lot of bad  quality fake gases in Iran.

C.Most of companies can not find good suppliers and secondly even if they find supplier they would have logistic problems  because of sanction but we have advantage in this case .

D.Also most of them have problems in releasing goods but we don’t  have the mentioned problems due to the expert team that we have for clearance.
