Machinery, Mechanical appliances, nuclear reactors, Steam boilers and parts thereof

Chapter 84 of The book of exports and imports generally includes many cases, but what is mostly exported to Switzerland from Iran includes the following:

  1. Taps, cocks, valves and similar appliances for pipes, boiler shells, tanks, vats or the like, including pressure-reducing valves and thermostatically controlled valves.
  2. Printing machinery used for printing by means of plates, cylinders and other printing components of heading 8442; other printers, copying machines and facsimile machines, whether or not combined, parts and accessories thereof
  3. Air or vacuum pumps, air or other gas compressors and fans; ventilating or recycling hoods incorporating a fan, whether or not fitted with filters.

Pressure-reducing valves

These valves are divided into two groups based on the tariff line

1.Gas pressure regulator used on liquid gas cylinders

2-Other pressure reducing valves. As the name implies, their main function is to reduce the high and variable inlet pressure and bring it to a low and constant outlet pressure.

Gas pressure regulator used on liquid gas cylinders

As mentioned, a pressure regulator is a device that reduces the gas pressure to a constant and lower pressure.

There are different types of regulators, such as:

1- Screw regulator

2- Pressure regulator

 The following is an example of pressure regulators. (Source: National Standards Organization)

  • Other pressure reducing valves

Pressure reducing valves are used for different types of fluids.

For example ,steam pressure relief valves have the task of reducing the steam pressure to a small and constant level. These valves have different types, which include:

  • Direct acting Pressure Reducing Valve

This type of valve has a simple operation and is used in cases where very precise steam control is not required.

  • Pilot Operated Pressure Reducing Valve

These types of valves are used for cases where precise steam control is required.


Export and import statistics, regulations

In general, the largest importers of these products (Chapter 84) in 2019 are the United States, China, Germany, Britain and France, respectively. Switzerland is the 32nd country to import these products in terms of commodity value, the main share of its import is from HS codes 8471, 8479, 8411, 8481. The global share of imports of these products in 2019 was equal to 2282491594 thousand dollars. (Source:

Meanwhile, the export of these products by Iran to countries in the world in 2019 has been as follows. The positive point of this figure is the existence of exports to European countries such as Germany, Spain and Italy, which shows the export potential of these products .

In total, Iran exported $ 359,000 worth of these products to Switzerland in 2019, which is 0.2 percent of the country's exports.

Some of the tariffs in this chapter are subject to mandatory regulations and standards of goods that must be observed during importing or exporting goods.
