 Legal inspection requirements for chargers and secondary lithium 
batteries for electrical bicycles and electrical assisted bicycles   
 
By the Bureau of Standards, Metrology and Inspection (BSMI), Ministry of Economic 
Affairs (MOE A.) 
 
Introduction:  
In order to enhance the protection of consumers, the B ureau of Standards, Metrology and 
Inspection (BSMI)  regulate s chargers and secondary lithium batteries for electrical bicycles 
and electrical assisted bicycles.  
For chargers, t he inspection standards are CNS 15425 -1 for safety, CNS 13438 for EMC, and 
section 5 of CNS 15663 for marking of presence conditions of 6 hazardous substances. For 
secondary lithium batteries, the inspection standards are CNS 15424 -1, 15424 -2 and 15387.  
The conformity assessment procedure  for all such products will be the Registration of Product 
Certification (RPC) Scheme  (Module II+ III).  
 
Date of implementation:  1 January 2019

Registration of Product Certification (RPC) Scheme(Module II+ III)  
 
Under this procedure, domestic manufacturers or importers must have their products 
type-tested in advance (Module II) before applying for registration of their products. 
Manufacturers or importers will also be required to ensure by declaration that all pro ducts 
made at their manufacturing facilities are in conformity with the prototypes submitted for type 
test at Module II stage, and the declaration procedure is called Module III (conformity -to-type 
declaration). The conformity -to-type declaration shall be raised by the manufacturer or the 
authorized local representative, declaring that the products mass -produced will comply with 
the prototype as described in the type -test report.  
 
Products will be allowed to use the Commodity Inspection Mark with the lette r “R” and the 2 
 identification number given by the BSMI, after they are certified and registered with the 
BSMI. These products can then pass through 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, the extra NT$3,000(about US $102)  of application fee is needed for every 
application in each certification.  
 
Related requirements:  
1. The inspection standards of the commodities  listed above will come into force  on the date 
of announcement and from January 1  2019  will be subject to mandatory commodity 
inspection before they can be marketed in Taiwan . When the BSMI completes the review 
procedure and approves the application, a certificate will be issued and valid for 3 years 
starting from the issue date.  
2. Where applicable, t he certificate holders of the commodities  shall follow  the content 
stipulated in Section 5 “Marking of presence” of C NS 15663 and clearly mark  “the 
presence condition  of the restricted substance s” on the bodies , packages, stickers, or the 
instruction books of the commodities . Those who utilize website as a means to announce  
“the presence condition  of the restricted substance s” of the commodities shall also clearly 
mark the website address on the body, packages, stickers, or the instruction books of the 
commodities.  In that case, t he requirements of Section 5.3 of CNS 15663 are not 
applicable to the  positions of the markings.  
3. The locations to apply for type testing
 the BSMI -designated testing laboratories.  
4. The locations to apply for Registration of Product Certification
 the BSMI or its branches.  
5. Sections 4.1, 4.2.3 and 4.3.5 of CNS 15425 -1(2015) are not applicable to  chargers for 
electrical  bicycles and assisted  bicycles use . 
6. 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 right next to  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 ident ifiable 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 
condition.  
3 
 “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 commodity exceeds the respective reference percentage value 
specified in Annex A to CNS15663.  
7. The C.C.C. Code listed in the table is used f or reference on ly. The commodities  listed in 
the table shall  still complete the inspection procedures before entering into the 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  
8. 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. Extra 7 working day s may be required for  additional tests.)  
9. 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. 
10. Commodities with combined features  or multifunction al products shall comply with the 
respective inspection standards and conformity assessment procedures of RPC scheme.  4
