I bought audiomoth units and cases from round 18 at groupgets. Surprisingly, the Customs is asking for the EU certificates or CE markings (?!?). I already explained the low-cost and experimental use of these units but they have asked repeatedly for these two certificates: IC 115 - RoHS directive 2011/65/EC   IC 124 - EMC directive 2014/30/EU  Can someone provide help on this urgently? I never had this request from the customs and I am already paying for the warehouse and at risk of a return. Thank you in advance
