1. Article 15 of Accounting Standards for Business Enterprises No.4-Fixed Assets stipulates that an enterprise shall reasonably determine the service life and estimated net salvage value of fixed assets according to their nature and use. Once the service life and estimated net salvage value of fixed assets are determined, they shall not be changed at will.

Accounting standards require that the depreciation period be determined according to the reasonable service life, but there is no clear figure for the specific period, which is generally understood as normal.

In other words, from the accounting point of view, this depreciation period is allowed within a reasonable time.

2. Article 60 of the Regulations for the Implementation of the Enterprise Income Tax Law of People's Republic of China (PRC) stipulates that the minimum depreciation period of fixed assets is as follows, unless otherwise stipulated by the competent departments of finance and taxation of the State Council:

(a) houses and buildings, for 20 years;

(2) Aircraft, trains, ships, machines, machinery and other production equipment, 10 year;

(3) Appliances, tools and furniture. 5 years related to production and business activities;

(4) Four years for vehicles other than airplanes, trains and ships;

(five) electronic equipment, for 3 years.

Here, the freezer obviously belongs to electronic equipment, so according to its regulations, the minimum life is 3 years.

The regulations are slightly different. In practice, in order not to increase the workload of income tax settlement, most enterprises will take the depreciation period of fixed assets as the depreciation period of fixed assets according to the provisions of the income tax law.
