When applying for the use of CNS Mark, a manufacturer may, in accordance with the provisions of 
Article 11 of the Regulations, make individual applications for manufactured products by following 
the requirements specified below. 
(i)The appropriate product classification is selected from the CNS Product List. 
(ii)Each product is limited to one application. However, where there are further classifications for 
the product, applications shall be made based on such classifications. One application is confined to 
each classification.
(iii)Separate applications shall be made for different products manufactured by the same factory. 
Where the same product is manufactured by different factories of the same company, separate 
applications shall be made in respect of different factories.
(2)Assessment of quality management systems (QMS) or factory inspection
Before applying for the CNS Mark, a manufacturer shall first apply for QMS certification to the 
BSMI-recognized QMS CBs or apply for factory inspection to the factory inspection agency/bodies 
based on the modules prescribed by the BSMI. According to Paragraph 2, Article 8 of the 
Regulations, the implementing units of BSMI, the BSMI-recognized QMS CBs or the factory 
inspection agency/bodies shall dispatch personnel to the manufacturer’s factory to perform QMS 
assessments or factory inspection, and prepare a report to be delivered to the manufacturer.
(3)Product inspection and testing
(i)Before applying for the CNS Mark, a manufacturer shall first apply to the implementing units of 
BSMI, the third-party certification bodies or BSMI-recognized testing laboratories for product 
inspection and testing. Based on Paragraph 2, Article 9 of the Regulations, upon acceptance of the 
application, the responsible unit or body shall sample products for testing after having confirmed the 
production processes (including final assembly or separate packaging) and testing management. 
(ii) The implementing units of BSM, the third-party certification bodies or BSMI-recognized testing 
laboratories shall conduct inspection/testing of the selected samples against national standards and 
the “List of CNS Mark Inspection Items.” Where the inspection items on the List are conducted in 
the manner of witness testing, an assessment of the factory or the testing laboratories specified by 
the manufacturer shall be performed to determine whether they have the facilities and capability 
required by the inspection items in accordance with relevant national standards. Where the 
assessment confirms compliance with the requirements, the testing shall be conducted under the 
supervision of the BSMI.
(iii)After completion of product inspection/testing (including witness testing) and confirmation of 
fees paid by the manufacturer, the implementing units of BSMI, the third-party certification bodies 
or BSMI-recognized testing laboratories shall prepare an inspection report to be delivered to the 
manufacturer. Copies of notice shall be sent to the certification unit of BSMI in accordance with 
Paragraph 2, Article 9 of the Regulations.
(iv)Where a manufacturer has obtained other certification marks specified and announced by the 
BSMI, the application for product inspection may be sent to the implementing units of BSMI, the 
third-party certification bodies or BSMI-recognized testing laboratories by submitting the latest 
product inspection/testing report for those certification marks under the circumstances that the 
registration is still valid. Upon acceptance of application, the responsible unit of BSMI or the 
responsible body shall compare the content of the product inspection/testing report with those 
specified in the “List of CNS Mark Inspection Items.” Items that comply with the CNS may be 
exempted from inspection/testing. Those that are not exempted shall be processed in accordance 
with the provisions prescribed in Clause 4(3)(i)-(iii). 
(4)For inspection items to which witness testing does not apply, where the circumstances stated in 
Article 10 of the Regulations are met, a manufacturer may apply to the certification unit of BSMI 
for witness testing by providing reasons.
(i)Huge and heavy products that are not easy for delivery;
(ii)Delicate and fragile products that are easily damaged;
(iii) Dangerous products that easily cause danger;
(iv)Manufacturer’s testing laboratories complying with CNS 17025 and accredited by Taiwan’s 
laboratory accreditation body or accreditation bodies that are located in the same country as the 
manufacturer and that signed the mutual recognition arrangement developed by the International 
Laboratory Accreditation Cooperation under the condition that the accredited scope covers the 
requirements specified in the applicable CNS concerning the product; or
(v)Other special circumstances approved by the BSMI.
(5)Upon receipt of the application for witness testing, the certification unit of BSMI shall notify the 
implementing units of BSMI, the third-party certification bodies or BSMI-recognized testing 
laboratories. An assessment shall be performed in accordance with Clause 4(4) to the 
manufacturer’s testing laboratories or the laboratories specified by the manufacturer to determine 
whether they have the facilities and capability required by the inspection items specified in relevant 
national standards. An “Evaluation Report on the Capability to Perform Witness Testing” shall be 
prepared based on the result of the assessment in order to determine whether an approval will be 
given to the application. The decision shall be made known in writing to the applicant manufacturer, 
with copies sent to the implementing units of BSMI, the third-party certification bodies and 
BSMI-recognized testing laboratories.
