 Legal Inspection Requirements  for Electronic Toilet Seat s 
 
By the Bureau of Standards, Metrology and Inspection (BSMI), Ministry of Economic Affairs  (MOEA.)  
 
Introduction:  
 The use of electronic toilet seats is becoming prevalent  in domestic households. As consumer ’s skin is in 
direct contact with the products, of which the installed environment  tends to be with high humidity and high 
temperature, concerns have been raised ab out hazards of electric shock and fire. With a view to protecting 
consumers from relevant hazards , the Bureau of Standards, Metrology and Inspection regulate s electronic 
toilet seats in aspects of safety (CNS 60335 -1 and CNS 60335 -2-84), EMC (CNS 13783 -1) and use of 
hazardous substances (Section 5 of CNS 15663). The conformity assessment proc edure will be Registration of 
Product Certification Scheme (Module II+IV, II+V, or II+VII)  or Type -approved Batch Inspection.

Description of the two kinds of conformity assessment procedures  
 
1. Registration of Product Certification (RPC) Sch eme: Modules II+IV , 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 -recognize d testing laboratories, but the quality 
management systems of the production premises must be in conformity with Module IV (Full Quality 
Management System), Module V (Production Quality Management System) or Module VII (Factory 
Inspection).  
For Module IV a nd 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 B SMI 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 allowed 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 the RPC certification is valid for 3 years. If there are any serial products, an extra 
NT$3,000 (about US$102) of application 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 products type -tested by the BSMI or 
the designated testing laboratories recognized by the BSMI, and file an application for Type Approval to 
the BSMI or its branches.  2 
 After manufacturers 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 f or 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 can also be found on the BS MI web site: 
http://www.bsmi.gov.tw/wSite/ct?xItem=8673&ctNode=811&mp=2  
 
Locations to apply for Registration of Product Certification:  
The BSMI or its branches.  
 
Time required for R egistration of Product Certification:  
14 work 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 days may be required if additional tests are required.)  
 
Related requirements:  
1. Electronic toilet seat  powered by USB cord/port DC 5V  and without a AC to DC adaptor, only powered  
by and with  power supply products for automotive cigar lighter , only powered  by three -phase or 
only-batteries shall not be subject to legal inspection .  
2. 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 and approves the applicatio n, a certificate 
will be issued and valid for 3 years.  
3. For the requirement of Section 5 “Marking of presence” of CNS 15663, the certificate holders of the 
commodities shall clearly mark the presence condition of the restricted substances on the body, packa ges, 
stickers, or the instruction books of the commodities. Those who utilize website as a means to announce 
the presence condition of the restricted substances of the commodities shall clearly mark the website 
address on the body, packages, stickers, or t he instruction books of the commodities, instead . 
4. The Commodity Inspection Mark:  
(1) The Commodity Inspection Mark shall be printed by the certificate holders. The identification number of 
the Commodity Inspection Mark consists of “Letter (R or T),” “Designate d Code (5 digits)” and the 
presence conditions of the restricted substance (e.g., RoHS or RoHS (XX,XX)).  
(2) The identification number shall be placed below or to the right of the graphic symbol and the presence 
conditions of the restricted substance shall be indicated in the second row.  
(3) The size  of the Mark can be applied proportionally on a prominent location of the commodities. The 
Mark shall use materials that are not easily altered, and the content shall be in a clearly  identifiable and 
indelible form aff ixed permanently  to the commodity . 
(4) For RPC scheme, the examples of the Commodity Inspection Mark are listed below:  
 
 
 
 
 
(5) For TABI scheme , the examples of the Commodity Inspection Mark are listed below:

 (6) “RoHS” indicates the content of restricted substance(s), other than exemptions stated in CNS 15663, 
does not exceed the reference percentage value of presence condition.  
“RoHS (XX,XX)” indicates the content of restricted substance(s) (element XX, element XX, …), other 
than exemptions stated in CNS 15663, exceeds the reference percentage value of presence condition.  
The restricted substances: indicates Pb, Cd, Hg, Cr+6, PBB, and PBDE.  
Example:  
 RoHS (Pb): indicates that the Pb percentage content in certain parts of the commodity exceeds the 
reference  percentage value of presence condition.  
 RoHS (Cd, Cr+6, PBB): indicates that the Cd, Cr+6, and PBB percentage content in certain parts of the 
commodity exceed the reference percentage value of presence condition respectively.  
5. The C.C.C. Codes listed in the form are used for reference only. The commodities shall still comply with 
the requirements before entering into the market, even though their C.C.C. Codes are identified differently 
by the Customs Administration, Ministry of Fin ance or Bureau of Foreign Trade, Ministry of Economic 
Affairs.  
6. The inspection standards of the commodities listed in the table shall be the version published in this 
announcement. If any updated version is available, the BSMI shall publish the implementati on date of the 
updated version in further announcements.  
7. Commodities with combined types or multifunction -products shall comply with the respective inspection 
standards and the conformity assessment procedures of RPC scheme.
