Many companies will view approvals purely as an expensive hindrance to commerce, but the reasons behind them can be justified. In reality, they serve to prevent the supply of potentially dangerous and poor-quality products into the marketplace. It is necessary to ensure that telecommunications products operate correctly when connected to the national infrastructure and do not constitute a risk to the safe and proper operation of the networks to which they are connected. China is no exception to this rule, the importation and supply of unapproved or 'grey'products can lead to prosecution and forfeiture of equipment by authorities.
The MII China - the Ministry of Information Industry stipulates the telecom approval regulations and the Telecommunications. Administration Bureau under the MII takes charge of telecom products approvals granted in the form of Network Access License (NAL). Each type of approved product will be issued an NAI-Network Access Identifier with the certification number.
