That is a distorted perspective. There was a study carried out in 2015.
From the Ai
Thailand's effective rate of protection on wine is 179.46%, which is significantly higher than the nominal tariff of 60%. This means the total cost of imported wine to a consumer is more than doubled due to various taxes and levies, according to a study published on Thai Journals Online (ThaiJO).
Explanation:
Nominal Tariff: The stated import tax on wine is 60%.
Effective Rate of Protection: This is the total cost of protection to domestic producers, including the nominal tariff and other indirect taxes or regulations.
The 179.46% effective rate: This figure indicates that the actual protection provided to local wine producers is much larger than the 60% nominal tariff. This means that imported wine is effectively priced 179.46% higher than it would be without these taxes, as noted in a study on ResearchGate.
This is how the calculation is made in the study.
"1.1.3 Tax Structure
In Thailand for wine there is a tariff of 60 percent on imports. All other taxes compound off from the imports cost, insurance and freight (CIF) plus the tariff cost. Domestic wine taxes are calculated just on the cost and not the remaining values of the CIF and import tariff. Because of this the tax burden falls more heavily on the importers, creating favorable advantage to domestic wineries."
