The dumping margin can be calculated once the export price and normal value are established. When comparing the normal value and the export price, it is important to use comparable product types, and to make adjustments for any differences affecting price comparability. Such differences include differences in physical characteristics (e.g. quality), level of trade, import charges, indirect taxes, transport costs and packing.

The difference between the normal value and the export price is the dumping margin, which is then expressed as a percentage of the cost, insurance and freight (CIF) export price (the price of the imported product at the EU border, not including customs duties, importers’ margins, transport costs in the EU, etc.).

Example of a dumping margin calculation (in euros)

a) Ex-factory normal value 100

b) Ex-factory export price 80

b) Dumping margin a-b 20

d) CIF value 90

e) Dumping margin as % of CIF value

è (c*100)/d=(20*100)/90=22 %

If the complaint refers to more than one exporting country, the dumping margin must be calculated for each country individually.

It is essential to provide all relevant statistical data at your disposal.

You should include all relevant evidence of export price and normal value in the complaint. Evidence can be presented in the form of invoices, price lists, specialised journals, offers, etc. As a general rule, evidence presented in complaints needs to be from reliable sources, and contain accurate information. In addition, it must relate to a period of 1 year, ending not more than 6 months preceding the submission of the complaint.
