The calculation of the dumping margin is to determine the amount of dumping first, which is equivalent to the difference (after making the necessary adjustments) between the export price of the product being investigated and the normal value of the product in the source country.
- Amount of Dumping = normal value - export price.
Example: Amount of Dumping = 85 – 80 = 5 . - Dumping Margin = (dumping/export price) X 100.
Example: Dumping Margin = (5 ÷ 80) X 100 = 6.25% more than de minimis (2%). - Dumping Duty (applied in customs) = (amount of dumping/export price at *CIF level)= 5 ÷ 90 =5.55%.
*CIF: The goods cost including insurance and ocean freight up to the buyers port.
In case there are multiple sources of imports from two different exporting products in a country, a single dumping margin is calculated for each cooperative source product separately and then a uniform margin is made for each country to be imposed on other non-cooperative companies.
If there are multiple varieties of the product in question, a weighted average of the dumping margins is calculated, resulting in a single dumping margin on all product items, noting that all the accounts made are provided to this margin.
