 Proposal for Amendment s to the Inspection Requirements for Polyvinyl Chloride 
Pipes 
 
By the Bureau of Standards, Metrology and Inspection (BSMI), Ministry of Economic Affairs  
 
Background:  
1. With a view to enhancing the performanc e of unplasticized polyvinyl chloride (PVC) pipes, 
which are currently subject to mandatory inspection, to meet  the needs of consumers, the 
Bureau of Standards, Metrology and Inspection (BSMI) proposes to update the inspection 
standards CNS 1298 (PVC pipes)  and CNS 4053 -1 (PVC pipes for water supply) to their current 
versions (published on 18 February 2017).   
2. PVC pipes are conducted in two kinds of conformity assessment procedures , namely 
Batch -by-Batch Inspection or Registration of Product Certification (Modules II+IV, II+V , or 
II+VII). To speed up customs clearance, BSMI modifies Batch -by-Batch Inspection  to Type 
Approved Batch Inspection .

Description of the two kinds of conformity assessment procedures  
1. Registration of Product Certification (RPC) Scheme: Modules II+IV, II+V, or II+VII  2 
 (1) 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 BSM I-designa ted 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).  
(2) 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 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 . 
(3) 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.  
(4) After being certified and registered by the BSMI, products will be allowed to use the Commodity 
Inspection Mark w ith the letter ‘R’ and the identification number given by the BSMI. Additionally, these 
products can clear the customs directly without any further inspection if not being sampled by RPC 
border check procedures. The application fee and annu al fee for RPC are both NT$5,000 (about US$170) 
for each certification, and a RPC certificate is valid for three  years. If there are any serial products, an 
extra NT$3,000 (about US$100) 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 B atch Inspection  
(1) Under this procedure, the manufacturer or importer shall have their products type -tested by the BSMI or 
BSMI-designated testing laboratories, and then file an application for Type Approval with the BSMI . 
(2) After manufacturers or importers obtain Type -Approval certificates, they are required to file an 
application for inspection with the BSMI before their products a re to be released from the production 
premises or arrive at the port of entry. The BSMI will then review the application and accompanying 
documents according to simplified procedures, and additional samples may be required for further 
testing. The fees for  type testing vary by product and depend on the testing laboratory. The fee for a 
Type Approval is NT$3,500, and a Type Approval certificate is valid for three years.  
 
Locations to apply for Type Testing:  
Tainan Branch of the BSMI or the BSMI -designated testing laboratories.  
 
Related requirements : 
1. The listed products that are composite products or multifunctional shall comply with the respective 
inspection standards. Where the components are subject to legal inspection, they shall also comply with 
relevant inspection standards.  
2. The inspection standards of the polyvinyl chloride pipes  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 announcements.  
3. The C.C.C. Codes listed in the table  are used for reference only.  Polyvinyl chloride pipes shall be 
complied  with the inspection procedures and standards  before entering into  the market, eve n though  their 
C.C.C. Codes  are identified differently by the Customs Administration, Ministry of Finance o r Bureau of 
Foreign Trade, Ministry of Economic  for tariff .
