@Demonstrative Bee : we got confirmation from UbiSoft that the Hazmat suit dlc is linked to the beta code we sent you (it proofs that you have pre ordered and so you can obtain this DLC bonus). As Ubisoft only allows one beta access per Uplay account you cannot register your second beta code but they confirmed that it can be easily fix with their customer support. They have all ability to transfer the Hazmat suit DLC after release when you will explain the situation and provide the second beta code. No worries :)
