There are many ways of restricting entry into the market. For the Intertek case, there are lots of ways that their restriction can be achieved. To start with, the government can restrict the use of foreign products in the tests. This will leave them with no option not to use the products from within. Secondly, a tax levy can be imposed on the foreign companies that are higher as compared to those that are local.
Another way is to let testing be done in specific languages and test results be documented in a language that is specifically understood in the country. This will discourage the foreign companies and have them involve a member of the state for aid. The government can insist that the testing team must consist of a government certified personnel. In doing this it will have insisted on the Germany company employing the locals if they must handle the jobs. In addition, it can insist on the wage paid to the local.
The government can as well decide to enforce the rule that ensures that the testing companies have been operational in the country for a given period of time so as to discourage new foreign companies from entering the market.
The main aim of these restrictions is to protect the locals by the government and keep their markets safe and secure by the introduction of competitive alternative goods from the foreign countries. Thus, it will be creating more opportunities to the locals to loom in businesses and invest. It will also have protected its market against foreign exploitations of the prices and introduction of illegal goods.
It will have also prevented the goods dumping practices that are carried out by some foreign companies as well as gain enough tax from those that will still persist.
