This article is about the national standards of the Republic of China administering Taiwan. For the national standards of the People's Republic of China, see Guobiao standards.

The national standards of the Republic of China administering Taiwan, Penghu, Quemoy and Matsu are titled the Chinese National Standards (CNS) (中華民國國家標準). They are administered by the Bureau of Standards, Metrology and Inspection of the Ministry of Economic Affairs. These standards are divided into 26 numbered categories. Applying the National Standards is voluntary unless authorities in charge cite any parts of the standards as laws and regulations. By the end of 2003, more than 15000 national standards have been issued. Although the Republic of China was removed in 1950 from the International Organization for Standardization (ISO) for failure to pay membership dues accordingly, there are still many National Standards translated from ISO standards into Chinese. A few standards also have English versions, but in case of any divergence of interpretation, the Chinese text shall prevail.

Because the Republic of China and the People's Republic of China can both be abbreviated as China[citation needed], the Chinese National Standards may also literally mean the National Standards of the People's Republic of China. However, the Republic of China has no plan to change the name "Chinese National Standards" yet.

Each standard has a general number and may be prefixed "CNS", such as CNS 11296. The general numbers, English names and any similar ISO standards of some standards are listed below:
