TABI Scheme  
 
Description of the two kinds of conformity assessment procedures  
 
1. Registration of Product Certification (RPC) Sch eme:  
(1)Module II+III  
Under the II+III combination of modules used in this scheme, domestic manufacturers or importers must have 
their products type -tested in advance (Module II) by the BSMI or BSMI -designated  testing laboratories before 
applying for registration of their products. Manufacturer s or importers will also be required to ensure by 
declaration (Module III, conformity -to-type declaration) that all products made at their manufacturing facilities or 
imported are in conformity with the prototypes submitted for type -test at Module II stage . The conformity -to-type 
declaration shall be drawn up by the manufacturer or the authorized local representative, declaring that the 
mass -produced products comply with the prototype as in the type -test report.  
(2)Module II+IV or II+V or II+VII  
For product  subject to Modules II+IV, II+V, or II+VII procedures, not only the products shall be type -tested in 
advance (Module II) by the BSMI or BSMI -recognized testing laboratories, but the quality management systems of 
the production premises must be in conformit y with Module IV (Full Quality Management System), Module V 
(Production Quality Management System) or Module VII (Factory Inspection).  
For Module IV and Module V, a registration certificate in accordance with the CNS 12681 (ISO 9001) series 
of standards is  required to be obtained from the BSMI, or certification bodies recognized by the BSMI. As for 
Module VII, a factory inspection report issued by the BSMI or BSMI -recognized factory inspection bodies is 
needed in the same way.  
In addition, a declaration of conformity -to-type is also required to ensure that the mass -produced commodities 
are in conformity with that shown in the type -test report for all the above three IV, V, VII modules.  
After being certified and registered by the BSMI, products will be allowe d to use the Commodity Inspection 
Mark with the letter ‘R’ and the identification number given by the BSMI. Additionally, these products can clear 
customs directly without any further inspection if not being sampled by RPC border check procedures. The 
application fee and annual fee for RPC are both NT$5,000 (about US$170) for each certification, and a RPC 
certific ate is valid for 3 years. If there are any serial products, an extra NT$3,000 (about US$102) of application 3 
 fee will be charged for every application in each certification. The fees for type testing vary by products and 
depend on the fee policies of the testing laboratories.  
 
2. Type -Approved Batch Inspection (TABI) Scheme  
Under this procedure, manufacturers or importers shall have their produc ts type -tested by the BSMI or the 
BSMI -designated testing laboratories, and file an application for Type Approval to the BSMI or its branches.  
After manuf acturers or importers obtain a Type Approval certificate, they are required to file an application for  
batch inspection to the BSMI each time before their products are released from the production premises or arrive at 
the port of entry. The BSMI will then review the application and the related documents while additional samples 
may be required for further  testing if it is deemed necessary.  
After the products have passed the inspection, they will be allowed to use the Commodity Inspection Mark with the 
letter ‘T’ and the identification number given by the BSMI. The application fee for a Type Approval is NT $3,500, 
and a Type Approval certificate is valid for 3 years. The fees for type testing vary by products and depend on the 
fee policies of the testing laboratories.  
*Further information on the two schemes ca n also be found on the BSMI web site: 
https://www. bsmi.gov.tw/wSite/lp?ctNode=9768&CtUnit=4132&BaseDSD=7&mp=2  
 
Locations to apply for Registration of Product Certification:  
The BSMI or its branches.  
 
Time required for Registration of Product Certification:  
14 work ing days. (This period does not include the time for corrective actions by the applicant due to deficiencies in 
the documents or samples. Extra 7 work ing days may be required if additional tests are required.)

3. The scope of CNS 13516 applies to water dispensers which are not connect ed directly  to the public water supply 
system  and the water is replenished  manual ly (distilled water type  not included ). Water dispensers can control 
water temperature , supply water with two or more  temperatures, and keep the water in an appropriate temperature.   
4. The scope of CNS 15929 applies to water dispensers which are not connect ed directly  to the public water supply 
system  and the water is replenished with  packaged drinking water  manually . The water dispenser s can control 
water temperature, and keep the water in  an appropriate temperature. The text “Water of t his water dispenser shall 
only be replenished  by packaged drinking water ” shall be labeled  on the body of the water dispenser and the 
instruction books.  
5. Sections 8.3 , 10, 13.(g), 13.(l), 13.(m)  of CNS 3910 are not applicable to instantaneous drinking water  suppliers 
without water storage tank.  
6. Upon the date of announcement of this measure, applications can be made to the BSMI for RPC certification. 
When the BSMI completes the review procedure an d approves the application, a certificate will be issued and 
valid for 3 years.   
7. Processing  of applications : 
(1) Replacement:  For product s with filtration material , the certificate holders  shall  apply to the BSMI or its branches 
for replacement of their certificate s by preparing type-test reports  and technical documents based on the
