USB-B interface certification will be abolished in new version of CTIA IEEE 1725,
Ieee 1725,

▍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)

MCM, an ideal one-stop agency, provides testing, certification and agent service for clients.

The Cellular Telecommunications Industry Association (CTIA) has a certification scheme covering cells, batteries, adapters and hosts and other products used in wireless communication products (such as cell phones, laptops). Among them, CTIA certification for cells is particularly stringent. Besides the test of general safety performance, CTIA also focuses on the structural design of cells, the key procedures of the production process and its quality control. Although CTIA certification is not mandatory, major telecom operators in North America require their suppliers’ products to pass CTIA certification, therefore CTIA certificate can also be considered as an entry requirement for the North American communications market.CTIA’s certification standard has always referred to IEEE 1725 and IEEE 1625 published by IEEE (Institute of Electrical and Electronics Engineers). Previously, IEEE 1725 applied to batteries without a series structure; while IEEE 1625 applied to batteries with two or more series connections. As CTIA battery certificate program has been using IEEE 1725 as the reference standard, after the issuance of new version of IEEE 1725-2021 in 2021, CTIA has also formed a working group to initiate a program of updating CTIA certification scheme.The working group extensively solicited opinions from laboratories, battery manufacturers, cell phone manufacturers, host manufacturers, adapter manufacturers, etc. In May of this year, the first meeting for CRD (Certification Requirements Document) draft was held. During the period, a special adapter group was set up to discuss the USB interface and other issues separately. After more than half a year, the last seminar was held this month. It confirms that the new certification plan of CTIA IEEE 1725 (CRD) will be issued in December, with a transition period of six months. This means that CTIA certification must be performed using the new version of the CRD document after June 2023. We, MCM, as a member of CTIA’s Test Laboratory (CATL), and CTIA’s Battery Working Group, proposed revisions to the new test plan and participated throughout the CTIA IEEE1725-2021 CRD discussions. The following are the important revisions:
