Two Resolutions on IEC 62133-2 Issued by IECEE,
IEC 62133-2,

▍Vietnam MIC Certification

Circular 42/2016/TT-BTTTT stipulated that batteries installed in mobile phones, tablets and notebooks are not allowed to be exported to Vietnam unless  they are subjected to DoC certifctaion since Oct.1,2016. DoC will also be required to provide when applying Type Approval for end products (mobile phones, tablets and notebooks).

MIC released new Circular 04/2018/TT-BTTTT in May,2018 which stipulates that no more IEC 62133:2012 report issued by overseas accredited laboratory is accepted in July 1, 2018. Local test is necessity while applying for ADoC certificate.

▍Testing Standard

QCVN101：2016/BTTTT（refer to IEC 62133：2012)

▍PQIR

The Vietnamese government issued a new decree No. 74/2018 / ND-CP on May 15, 2018 to stipulate that two types of products imported into Vietnam are subject to PQIR (Product Quality Inspection Registration) application when being imported to Vietnam.

Based on this law, the Ministry of Information and Communication (MIC) of Vietnam issued the official document 2305/BTTTT-CVT on July 1, 2018, stipulating that the products under its control (including batteries) must be applied for PQIR when being imported into Vietnam. SDoC shall be submitted to complete the customs clearance process. The official date of entry into force of this regulation is August 10, 2018. PQIR is applicable to a single import to Vietnam, that is, every time an importer imports goods, he shall apply for PQIR (batch inspection) + SDoC.

However, for importers who are urgent to import goods without SDOC, VNTA will temporarily verify PQIR and facilitate customs clearance. But importers need to submit SDoC to VNTA to complete the entire customs clearance process within 15 working days after customs clearance. (VNTA will no longer issue the previous ADOC which is only applicable to Vietnam Local Manufacturers)

On July 19th 2022, Chinese Ministry of Industry and Information Technology release the latest GB 4943.1-2022 Audio/video, information and communication technology equipment – Part 1: Safety requirement. The new standard will be implemented on August 1st 2023, replacing GB 4943.1-2011 and GB 8898-2011. For products that already certified with GB 4943.1-2011, applicant may refer to the collection of differences between the old and new standard, so as to prepare for update of new standard.If you need an update of GB 4943.1 certification, you need to conduct supplement test according to your products. You may refer to the chart above to see if your products can meet the requirements of new standard.This month, IECEE issued two resolutions on IEC 62133-2 concerning the selection of upper/lower limit charging temperatures of cell and the limited voltage of battery. The following are the details of the resolutions:The resolution clearly states: In the actual test, no carrying out the +/-5℃ operation is acceptable, and charging can be carried out at the normal upper/lower limit charging temperature when charging in the manner of Clause 7.1.2 (requiring charging at upper and lower limit temperatures), though Appendix A.4 of the standard states that when the upper/lower limit temperature isn’t 10°C /45°C, the expected upper limit temperature shall be increased by 5°C and the lower limit temperature needs to be reduced by 5°C.In addition, the Panel of IEC SC21A(Sub-Technical Committee on Alkaline and Non-Acidic Batteries) intends to remove the +/-5℃ requirement in Appendix A.4 in the case of IEC 62133-2:3.2017/AMD2.
