In order to better serve the enterprises and play a role in the market, the office of the Customs Tariff Commission of the State Council has continued to optimize the marketization procurement declaration system for the US and Canada. To increase the function of purchasing the month's purchase plan, submit the third month purchase plan, and upgrade other functions. We should speed up the application of enterprises to exclude applications, raise the speed of approval for the purchase plan below US $3000, and give priority to the exclusion of applications near the time of importation. In the near future, the approved procurement plan, transaction record and exclude numbering will also be open and modified.
