If the production of lightweight Concrete blocks in a particular country has a low production cost, it can make exporting to other countries more attractive. This could be due to access to cheap raw materials, low cost labor or advanced technology and equipment. Export value depends on demand and destination market. If the destination country has a large market for lightweight concrete blocks and the demand for them is high, exporting can be advantageous. Also, if the standards and needs of the destination market are consistent with the products produced in the country of origin, the export value will increase. The increase in the need for construction in countries can cause the need for AAC and ACB light concrete blocks to increase. This may be due to population growth, housing needs, infrastructure development, and industrial and commercial construction projects.

Trade policies and import and export restrictions can also be influential. In some cases, import tariffs may reduce the incentive to import AAC and ACB lightweight concrete blocks, and as a result, countries act as importers. Economic factors can also play an important role in countries' decisions to import and consume AAC and ACB light concrete blocks. It may be that the cost of domestic production for similar blocks is very high and imports from other countries are more economical. Also, inflation rate, exchange rate, transportation cost and other economic factors are also influential. Regulations and standards related to the construction and use of lightweight concrete blocks may differ in countries. Some countries may have stricter standards for the use of these products and, as a result, act as importers. The biggest target markets for the export of lightweight concrete blocks are:

• China is one of the largest markets for lightweight concrete blocks in the world. Due to the expansion of constructions and the ever-increasing need for housing and urban infrastructure, the market of lightweight concrete blocks in China is very dynamic.
• India also has a significant market for lightweight concrete blocks with its high population and the need for construction in the housing and urban infrastructure sectors. The rapid growth of urbanization in India has increased the demand for Construction materials .
• The lightweight concrete block market in the United States is also large and booming. This country uses light concrete blocks for residential, commercial and industrial construction.
• Considering the housing reserves in Brazil and the need for construction, the market of lightweight concrete blocks in this country also has a high potential.
• Due to the size of the population and the need for construction in Russia, the market of lightweight concrete blocks is also significant in this country.
• Also, countries like Hong Kong, Japan, Germany, Netherlands, Australia and Canada are also listed as countries that have a large market for lightweight concrete blocks.

AAC and ACB light concrete blocks have physical and mechanical properties such as lightness, thermal insulation, sound insulation, fire resistance and compatibility with the environment. These features can be considered by countries as one of the main advantages of using this type of blocks in buildings. The production of AAC and ACB light concrete blocks requires special technology. Some countries may be able to produce self-sufficiently because of sufficient experience and technical knowledge in this field as well as the existence of real industries compatible with the production of these products. In cases where countries do not have access to the necessary technology and know-how, they may act as importers of these products. The production of AAC and ACB light concrete blocks requires special raw materials that may be difficult to supply in some countries.

If a country does not have access to the raw materials necessary to produce lightweight concrete blocks, it may act as an importer of these products. If there is competition for light concrete blocks in the world market and other countries have similar production, the level of competition will be effective. If production in the country of origin reduces costs and increases quality and innovation, exporting can have an advantage. Trade policies and export and import restrictions are important variables in evaluating the value of exporting lightweight concrete blocks to other countries. Tariffs, customs restrictions or incentive programs for domestic industries may be effective in the destination country and production in the destination country may be more economical.
