 Legal Inspection Requirements for Wireless Charger s 
 
By the Bureau of Stan dards, Metrology and Inspection , Ministry of Economic Affairs  
 
Introduction:  
Wireless charger s are widely used to charge electronic devices , such as tablet s or mobile 
phones. A survey of such products raised safety concerns in aspects of overheating, 
fire-resistance and others. In order to  protect consumers from relevant hazards arising from 
the use of such products and to protect the environment, the Bureau of Standards, Metrology, 
and Inspection (BSMI) regulate s the safety, EMC , and hazardous substances of wireless 
charger prod ucts. The inspection standards are CNS 14336 -1 for safety, CNS 13438 for EMC , 
and Section 5 of CNS 15663 for marking of the presence of six hazardous substances , 
including Lead  (Pb), Mercury  (Hg) , Cadmium  (Cd) , Hexavalent Chromium  (Cr+6), 
Polybrominated Bi phenyls  (PBB) , and Polybrominated Diphenyl Ethers  (PBDE) . Where t he 
main working frequency of the wireless chargers is less than 30MHz, they shall also comply 
with the magnetic field radiation requirements  of CNS 13803 (2003). The conformity 
assessment pro cedure shall  be Registration of Product Certification (Module II Type Test + 
Module III Conformity to Type Declaration).

Registration of Product Certification (RPC) Scheme  (Module II+ III)  
 
Under this scheme, domestic manufacturers or importers shall have their products type -tested 
in advance (Module II) by the BSMI or BSMI -recognized testing laboratories before applying 
for registration of  their products. Manufacturers or importers are also required to ensure by 
declaration (Module III) 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 (Module III ) declaration shall be made  by the manufacturer or the 
authorized local representative, declaring that the products comply with the prototype as 
described in the type -test report.  
Products  are allowed to use the Commodity Inspe ction Mark with the letter “R” and the 
identification number given by the BSMI, after they are certified and registered with the 
BSMI. These products can then clear  customs directly without any further inspection. The 
application fee and annual fee for RPC are both NT$5,000  (about US $170)  for each 
certification, and the RPC certifications are valid for three years. If there are any serial 
products, an extra NT$3,000  (about US $102)  of application fee is needed for every 
application in each certification.  
 
Related requirements:  
1. 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 
application, a certificate  will be issued and valid for 3 years.  2 
 2. Where t he main working frequency of the wireless charger s is less than 30MHz, they 
shall comply with the magnetic field radiation  requirements  of CNS 13803 (2003).  
3. Locations to apply for type testing : the BSMI  designated testing laboratories.  
4. Locations to apply for Registration of Product Certification : the BSMI or its branches.  
5. Time required for Registration of Product Certificatio
 14 working days. (This period 
does not include the time for corrective actions by the applicant due to deficiencies in the 
documents or samples. An e xtra 7 working days may be required for additional tests.)  
6. According to the “Regulations Governing the U se of Commodity Inspection Mark ,” the 
obligatory inspection applicant shall affix the Commodity Inspection Mark to the 
products  in obvious place s after the products  are certified under the Registration of 
Product Certification  Scheme . 
7. The technical documents and accessories to be attached to the type testing shall compl y 
with the requirement s of the “Directions Governing Type Approval  of Electrical and 
Electronic Commodities .” 
8. The t ype test ing fees shall be charged by the designated testing  laborator ies. 
9. The related fees for  the Registration of Product Certification shall be charged in 
accordance with the relevant provisions of the “Regulations Governing Fees for 
Commodity Inspection .” 
10. For the requirement of Section 5 “Marking of presence”  of CNS 1566 3, the certificate 
holders of the commodities shall  clearly mark  the presence condition of the restricted 
substances on the body, package s, stickers , or the instruction books of the commodities . 
Those who utilize  website as an alternative means to announce the presence condition of 
the restricted substance s of the commodities  shall  clearly  mark  the website address on the 
body, package s, stickers,  or the instruction books of the commodities . 
11. 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 “ A Letter  (R or 
T),” “Designated Code (5 digits )” and “the p resence 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 locat ion 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 affixed permanently to the 
commodity.  
(4) For RPC scheme, the examples of the Commodity Inspection Mark are listed below:  
 
 
 
 
(5) “RoHS” indicates that the content of restricted substance(s), other than exemptions 
stated in CNS 15663, does not exceed  the reference percentage value of presence 
3 
 condition.  
“RoHS (XX,XX)” indicates that 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.  
Restricted substances: Pb, Cd, Hg, Cr+6, PBB, and PBDE.  
Examples :  
 RoHS  (Pb) indicates that the percentage content of Pb in certain parts of the 
commodity exceeds the  reference percentage  value specified in Annex A to CNS 
15663.  
 RoHS  (Cd,Cr +6,PBB) indicates that the percentage content of Cd, Cr+6, and PBB 
in certain parts of the co mmodity exceeds the respective reference percentage value 
specified in Annex A to CNS  15663.  
12. 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 implementation date of  the updated version in further announcement s. 
13. The C.C.C. Code listed in the table is used f or reference only. The commodities  listed in 
the table shall  still complete the inspection procedures before entering into t he market 
even though their C.C.C. Code s are identified differently by the Customs Administration, 
Ministry of Finance , or the Bureau of Foreign Trade,  Ministry of Economic Affairs  
14. Commodities with combined features  or multifunction al products shall comply  with the 
respective inspection standards and conformity assessment procedures of RPC scheme.  4
