At the moment, getting EDS and crypto-codes is MAH responsibility. As a distributor you should receive a serialized product according to Uzbekistan regulations from MAH. MAH should get the electronic signature, describe their products in National Catalogue and apply codes on the packs.
If there is no technical possibility to apply codes on the plant, you can integrate your T&T system with distributors T&T system and manage the crypto- ordering process by your distributor on behalf of MAH, using this integration.
