Iran's domestic price system is severely distorted due to the U.S. blockade, which has caused the exchange rate to plummet.
This makes it very difficult to compare prices of goods with foreign prices.
When the real exchange rate against the dollar falls, suppliers immediately raise the prices of food, appliances, automobiles, etc., so that these prices are the same as international prices.
On the other hand, large machine tools, trucks, and buses cannot be easily exported, making it difficult for suppliers to raise their prices and making them unusually cheap compared to international prices.
For example, medium-sized buses with seating capacity of 50 passengers are sold at 1/10 to 1/20 of the international price.
Heavy-duty trucks in the 50-ton class are also about 1/10th of the international price.
Conversely, companies that sell automobiles and home appliances are using the weak currency as an excuse to raise prices and rake in huge profits.
Bicycle prices are often many times cheaper than in Japan, and batteries are relatively inexpensive.
Comparing the price of machine tools with Japan, the price of a laser welder is the same, but the price of a large CNC with 5-axis control is in some cases 1/10 of the price in Japan.
Conversely, the price of small welding machines seems to be the same as in Japan.
For this reason, it is nearly impossible to estimate the cost of equipment procured by Iran.
