In fact, exporting, the exporter acts in one or more ways. There are requirements of the legislation of our country and at sending from OUR country these indicators have to be accurately checked and correspond to the declared norms. However, there are requirements of the countries to which the products are exported and these requirements can be regulated at the state level (this will be specified by agreement between the countries. For example in free access on the website of the State Food Service) .
For example, studies of GMOs, heavy metals, antibiotics - these indicators are usually different from our legislation and indicators that are regulated in our country. Thus, the exporter must take this into account and contact the laboratory and agree on the sensitivity of the method, the method itself, the uncertainty and whether this study falls within the scope of accreditation. There are cases when our state has its own requirements, a foreign country to which the export is sent has its own requirements and even the buyer also has its own requirements. Therefore, it is necessary to take into account the requirements of 3 parties.
It should also be noted that each type of product has its "painful" points, somewhere it is antibiotics, somewhere it is heavy metals, somewhere it is microbiological indicators. Each area of the food industry has its nuances, which must be checked very carefully.
Each country has its own criteria for assessing product safety. Example. In our country (in Ukraine) Cadmium is normalized in some products at the level of 1 microgram, and abroad it is normalized - 0.1 micrograms. And if you research in a Ukrainian laboratory, not agreeing on these values, and send the products to another country, they can check there and as a result the products will not be allowed on the market. Therefore, it is important to agree on all indicators, methods, etc.
