The canteen needs a business license to sell ice cream, yogurt and other things.

a business license is a certificate issued by the administrative department for industry and commerce to industrial and commercial enterprises and individual operators to engage in a certain production and business activities. Its format shall be uniformly stipulated by the State Administration for Industry and Commerce.

company canteens (including canteens that only provide services for employees in the company and canteens that provide catering services to the outside world) must apply for a catering service license, but whether or not to apply for a business license should be determined according to whether it is for profit. If the unit canteen only provides services for employees within the unit, and the wages and benefits of all catering service personnel, the raw materials purchased by the canteen and all the income of the canteen are paid and managed by the unit to which the canteen belongs, that is to say, the main purpose of opening the canteen is to provide benefits and solve difficulties for internal employees, not for profit, then there is no need to apply for a business license. On the other hand, if the unit canteen does not pay the wages and benefits of the catering service personnel, and some even charge them the contract money instead, then the catering service provided by the canteen operator (or contractor) must exist for profit. In this case, the canteen operator (or contractor) should apply for a business license whether it only provides catering services to employees within the unit or also provides catering services to the outside world.
