▍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)

Lithium-ion batteries have been widely used as rechargeable batteries since the 1990s due to their high reversible capacity and cycle stability. With the substantial increase in the price of lithium and the increasing demand for lithium and other basic components of lithium-ion batteries, the increasing shortage of upstream raw materials for lithium batteries is forcing us to explore new and cheaper electrochemical systems based on existing abundant elements. Lower-cost sodium-ion batteries are the best option. Sodium- ion battery was almost discovered together with lithium-ion battery, but because of its large ion radius and low capacity, people are more inclined to study lithium electricity, and the research on sodium-ion battery almost stalled. With the rapid growth of electric vehicles and energy storage industry in recent years, the sodium-ion battery, which has been proposed at the same time as lithium-ion battery, has again attracted people’s attention.Lithium, sodium and potassium are all alkali metals in the periodic table of the elements. They have similar physical and chemical properties and can be used as secondary battery materials in theory. Sodium resources are very rich, widely distributed in the Earth’s crust and simple to extract. As a substitute of lithium, sodium has been paid more and more attention in battery field. The battery manufacturers scramble to launch the technology route of sodium-ion battery. Guiding Opinions on Accelerating the Development of New Energy Storage, Scientific and Technological Innovation Plan in the Energy Field during the 14th Five-Year Plan Period, and Implementation Plan for the Development of New Energy Storage during the 14th Five-Year Plan Period issued by the National Development and Reform Commission and the National Energy Administration have mentioned to develop a new generation of high-performance energy storage technologies such as sodium-ion batteries. The Ministry of Industry and Information Technology (MIIT) has also promoted new batteries, such as sodium-ion batteries, as ballast for the development of the new energy industry. Industry standards for sodium-ion batteries are also in the works. It is expected that as the industry increases investment, the technology becomes mature and the industrial chain is gradually improved, the sodium-ion battery with high cost performance is expected to occupy part of the lithium-ion battery market.
