 Proposal for Legal Inspection Requirements for Headphones  
 
By the Bureau of Standards, Metrology and Inspection (BSMI), Ministry of Economic Affairs (MOEA.)  
 
Introduction:  
 Nowadays, headphones are widely used. The excessive use of smartphones and audio devices with 
headphones may cause hearing loss of consumers. In order to enhance consumer protection, the BSMI intends 
to regulate the inspection requirements for headphones. Two alter native  conformity assessment procedures  are 
made available for the choice of applicants, i .e. Registration of Product Certification (RPC) or Type -Approved 
Batch Inspection (TABI).  
  
Proposed date of implementation:  1 January  2024

(Modules II+III)  
or 
TABI Scheme  
 
Description of the two kinds of conformity assessment procedures  
 
1. Registration of Product Certification (RPC) Sch eme: Modules II+I II 
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. Manufacturers or importers will also be 
required to ensure by declaration  (Module III, conformity -to-type de claration) 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 submitted  by the  manufacturer or the importer , 
declaring that the mass -produced  products comply with the prototype as in the type -test report . 
 
2. Type -Approved Batch Inspection (TABI) Scheme  
Under this procedure, manufacturers or importers shall have their products type -tested by the BSMI or 
BSMI -designated testing laboratories, and file an application for Type Approval to the BSMI or its 
branches.  
After manufacturers or importers obtain a Type Approval certificate, they are required to file an 
application for batch inspection to the BSMI each tim e 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 the Type 
Approval is NT$3,500, and a Type Approval certific ate is valid for three  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.  
 2 
 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 seven work ing days may be required if additional tests are 
required.)  
 
Related requirements:  
1. The listed commodities wil l be inspected for import and domestic products since 1 January 2024. The 
import  regulation code s is C02. From the announcement date, the BSMI  can accept applications for Type 
Approval or Registration of Product Certification for listed commodities.  
2. Those who apply for a certificate to the BSMI  from the date of announcement shall provide the type test 
report that meets the inspection standards, the location of the restricted substance content label, the 
sample (such as Table 1 and Table 2), and the re stricted substance content labeling statement. The 
certificate shall be issued after the examination by the BSMI . The validity period of the certificate shall be 
three  years from the date of issuance (if the date of issuance is before 31 December 2023 , it shall be 
counted from 1 January  2024 ). 
3. Those commodities using AC power source , rechargeable lithium batteries or affixed power altering 
devices shall be conformed to safety testing requirements (CNS 15598 -1). 
4. For the listed products use button -type batte ries to provide power, they shall comply with the relevant 
provisions of the CNS 15598 -1 standard for button -type batteries.  
5. 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, packages, 
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 the instruction books of the commodities, instead . 
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 “Letter (R or T),” “Designated 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 s ymbol 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, an d 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:

(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.  
3 
 “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.

commodity exceed the reference perc entage value of presence condition respectively.  
7. The C.C.C. Code listed in the table  are used for reference only. The commodit y shall still comply with the
