If goods enter the EAEU from a third country, then a member of the EAEU is obliged to deposit the amount received from customs duties into the common treasury, and then it is distributed among the members of the union.
Russia receives the largest share – 85%. In the past, Belarus, which has 4.86%, has repeatedly called for a review of the established standards for the distribution of duties, calling them "unfair".
Representatives in the EAEU from Kazakhstan (6.95%), Armenia (1.22%) and Kyrgyzstan (1.9%) are now already talking about recalculating the distribution of profits. But Lukashenko and Putin oppose this.
