NTC issued new regulation on 2019/Aug/7. The main changes are as follows, please refer to it.
1.NTC certificate now only allowed list 1 module brand / model per end-product model from 2019/8/7. For End products such as WLAN only, NTC only allows one WLAN module brand/model on per certificate. (it means one certificate cannot be listed with more than 2 module brands / models at the same time). If the end-product is WLAN+WWAN+RFID or NFC, one brand/model of each module can be placed on the certificate of one model end-product. If there are more than 2 brands / models for each module you need to apply for additional NTC certificates.
2. If the product has multiple different Marketing names need apply for their respective certificates separately.
