Buying bitumen
Buying Bitumen| Buying Bitumen This chemical material, which is composed of a mixture of carbon and hydrogen, is
important for its use as a material in various industries. Bitumen is obtained from nature or from the oil refining process.
Bitumen has adhesive and waterproof properties and is used as a main material in the production of asphalt and waterproof materials, and
bitumen is also used as a main material in the production of bitumen oil, flooring, thermal insulation and sealing materials.
Buying Bitumen is also common in the road construction and construction industries as a main material and has very high adhesive
properties, which makes it a suitable material for use in wet and water environments.
Buying Bitumen Since this material is a natural material and its use as a main material in various industries helps to preserve the
environment. It is also known as a suitable material for use in construction and building maintenance due to its waterproof properties and
high adhesion.
Types of Export Bitumen
Bitumen is a natural substance that is the result of the natural dissolution and evaporation process of
organic materials such as wood, coal and oil. And it has various types:
Petroleum: This type is obtained from the oil distillation process. Petroleum bitumen is usually used as a packaging and
sealing material. Its most common use is in the paving and construction industries.
Wood: Wood bitumen is obtained from the wood distillation process and is usually used as a waterproof and insect
repellent. This type has more applications in the wood and construction industries.
Coal: Coal bitumen is obtained from the coal distillation process and is usually used in the coating and anti-rust
industries.
Plastic: This type is obtained from the distillation of plastic materials and is used as an engineering material in various
industries such as paving, coating, and anti-rust. Each of these types has its own properties and applications and is
selected depending on the need and industry used.
Customs conditions for buying bitumen
To export bitumen, a customs declaration must be issued. A customs declaration is an official document that contains
information about the exported goods, such as value, weight, and destination.
In addition to the above conditions, exported bitumen must have the necessary licenses from relevant organizations. In
Iran, the issuance of bitumen export licenses is the responsibility of the Commodity Exchange Organization.
By observing these customs conditions, quality export bitumen can be produced and exported in accordance with
international standards.
Essential standards for purchasing bitumen
Essential standards for bitumen are standards that determine the physical and chemical properties of bitumen. These
standards are usually determined by international organizations such as ASTM and ISO.
The most important bitumen standards are:
ASTM D 946 (PEN Grade): This standard classifies bitumen based on the degree of penetration. The degree of
penetration is a measure of the softness and flexibility of the bitumen.
ASTM D 2872 (VG Grade): This standard grades bitumen based on viscosity. Viscosity is a measure of the bitumen’s
resistance to flow.
AASHTO M 320 (PG Grade): This standard classifies bitumen based on its performance in various environmental
conditions. In addition to the above, there are other standards that determine specific properties of bitumen. For
example, ASTM D 4402 measures the adhesion of bitumen. ASTM D 6923 measures the tensile strength of bitumen.
Iran’s ranking in the world for buying its bitumen
According to Iranian customs statistics, Iran’s bitumen exports in 2022 ranked fourth in the world. Iran exported more
than 5.4 million tons of bitumen in 2022, worth more than $1.5 billion.
Iran’s bitumen exports are made to various countries, including Turkey, Iraq, China, India, Afghanistan, Pakistan, Italy,
Spain, and Russia. Iran also ranks seventh in the world in terms of bitumen production. Iran produced more than 6
million tons of bitumen in 2022.
Buying Iranian bitumen has been welcomed by various countries due to its high quality. Buying Iranian bitumen is
perfectly suitable for building roads and civil infrastructure due to its high resistance to abrasion and high temperatures.
Given the high quality of Iranian bitumen and the increasing demands for bitumen purchase in the world, Iranian
bitumen exports will also increase in the coming years.
What are the most commonly used export bitumen grades for bitumen buying?
In general, grades 60/70 and 85/100 are the most commonly used export grades of bitumen for buying bitumen. These
grades are of high quality and are suitable for building roads and civil infrastructure.
Grade 60/70 is suitable for colder climates. This grade has high flexibility and has shown good performance at low
temperatures.
Grade 85/100 is suitable for warmer climates. This grade has high resistance to abrasion and has shown good
performance at high temperatures. In addition to these grades, there are other grades for bitumen export. For example,
grade 70/100 is suitable for moderate climates. Bitumen exporters must select and recommend the appropriate grade of
bitumen for buying, considering the conditions of the destination country and the needs of the buyer.
Below, we will examine the features of each of the mentioned grades:
Bitumen 60/70
Penetration degree: 60 to 70 seconds
Pour point: 20 to 30 degrees Celsius
Tack: 10 to 12 mm
Hardness: 30 to 35
Durability: 150 to 180
Bitumen 85/100
Penetration degree: 85 to 100 seconds
Pour point: 40 to 50 degrees Celsius
Tack: 12 to 14 mm
Hardness: 40 to 45
Durability: 200 to 220
Bitumen 70/100
Penetration degree: 70 to 85 seconds
Pour point: 30 to 40 degrees Celsius
Tack: 11 to 13 mm
Hardness: 35 to 40
Durability: 170 to 190

Iranian Standard for Bitumen
The most important bitumen standards in Iran are:
The National Standards Organization of Iran (ISIRI) has developed various standards for bitumen and bituminous materials. These standards
determine the physical and chemical properties of bitumen and are essential to ensure the quality and proper performance of bitumen in
various applications.
Iranian National Standard No. 2950: Determines the properties of bitumen and bituminous materials. ASTM D 946 classifies bitumen
based on the degree of penetration.
Iranian National Standard No. 12505: Determines the properties of road bitumens. ASTM D 6927 classifies road bitumens based on
their performance in different environmental conditions.
Iranian National Standard No. 12506: Determines the properties of emulsion bitumens. ASTM D 2397 classifies emulsion bitumens
based on the type of emulsifier and their physical properties.
In addition to these standards, there are other standards that determine specific properties of bitumen. For example, ISIRI standard 2962
measures the adhesion of bitumen. ISIRI standard 6923 measures the tensile strength of bitumen.
Manufacturers of this product must comply with the Bitumen Standards in Iran (ISIRI) to ensure that their products are suitable for use in
the intended applications.
