Lithium-ion battery CCC certification has been implemented mandatory

Starting from August 1, 2024, the CCC certification for lithium batteries has been mandatory, which means that lithium-ion batteries or mobile power banks need to obtain 3C certification to be legally sold in domestic production, sales, imports, and other activities. 3C certification is not only applicable to domestic companies but also to foreign customer companies imported into China. E-commerce platforms now require mobile power products to provide 3C certification before they can be sold on the platform.

Has your product obtained CCC certification? The following is a summary of the application scope of 3C certification and the sharing of common problems with 3C certification!

The scope of certified products is shown in the table below:

The following are the answers to the most frequently asked questions about 3C certification for lithium batteries(Q&A):

1. For earphone charging boxes, if the rated capacity of the internal battery is not more than 600mAh, does it need to be CCC certified?

Charging boxes with a capacity of less than 600mAh do not need to be CCC certified according to mobile power supplies, but the internal battery/battery pack of the charging box needs to be CCC certified.

Q2. For earphone charging boxes, if the rated capacity of the internal battery is greater than 600mAh, do the earphones have to be included in the list for control? CCC certification?

A. The charging box needs to be CCC certified according to the mobile power supply;

B. The internal battery/battery pack of the charging box needs to be CCC certified;

C. If the company wants to include the earphones in the list of charging boxes, for the earphones included in the same certification unit, the internal lithium battery/pack should also be CCC certified, and the earphones should be tested for GB4943.1 sound pressure.

3. If the battery of the mobile power supply is a certified battery pack (the battery pack is certified), does it still need to be tested according to GB 31241-2022?

The whole mobile power supply is no longer tested for GB 31241, but only GB 4943.1.

4. If both the product and the battery cell are CCC certified, but the battery pack has been assembled into a semi-finished product, the battery cell cannot be 3C-marked. How should we deal with this part?

After obtaining the CCC certificate, the battery cell to be sold from the factory must be CCC-marked. However, the battery cell before obtaining the CCC certificate and the battery cell that has been sold from the factory can be unmarked.

5. The battery cell is a battery pack that is self-produced and sold and randomly tested. After the battery pack obtains CCC, it is marked with the CCC Logo. Does the battery cell need to be marked with CCC?

The battery cell is randomly tested and has not obtained the CCC certificate, so the CCC Logo cannot be marked. After August 1, 2024, the battery cell needs to be CCC and marked with the CCC Logo.

6. What kind of organizational structure of the production enterprise relationship can meet the conditions of self-production and self-sale? Head office or parent company?

It is generally believed that if the products produced by the enterprise are used for reprocessing and production in the next link (the product is sold to itself), the conditions for self-production and self-sale are met. The head office and branch belong to the same legal person and meet the conditions for self-production and self-sale; the parent and subsidiary companies do not belong to the same legal person and do not meet the conditions for self-production and self-sale.

7. Should lithium-ion batteries used in medical devices (such as batteries in blood pressure monitors and blood glucose meters) be CCC certified by GB 31241-2022?

Lithium-ion batteries and battery packs used in medical devices are not within the scope of GB 31241 standards and do not need to apply for CCC.

8. Does the car emergency starting power supply belong to a mobile power supply?

The car emergency starting power supply itself does not belong to a mobile power supply, but when the car emergency starting power supply contains a similar USB output port, it can charge other information technology equipment and has a mobile power supply function, it can only be assessed for the functions in the CCC catalogue, that is, the mobile power supply function, and the certificate clearly states "only the mobile power supply function is assessed".

9. To meet the various market demands, the whole machine products sold by our company have been labelled with multiple brands or changed to multiple models, but the whole machine products have not changed. In this case, does our company only need to apply for one CCC certification? Or does each brand and each model need to apply for a separate CCC certification?

If the unit division requirements are met, multi-model products can apply for CCC as one unit; multiple brands need to apply for CCC separately.

10. Regarding the second point of battery pack unit division, the same type of battery components, does the same type mean that they must be cells with the same chemical composition or that the soft pack/hard shell is the same? Or must the CELL model be the same?

The type here refers to cylindrical, soft pack, hard shell, etc. However, the chemical composition of the battery components is the same, so they can be matched to form a battery pack.

The following materials are required for battery 3C certification application:

(1) Certification application form;

(2) Product specification sheet;

(3) Safety key parts list, operating parameters, battery nameplate, battery pack nameplate, battery internal cross-section diagram, battery pack circuit diagram and layout diagram;

(4) Business license of the manufacturer;

(5) Battery and battery pack specification sheet, Chinese nameplate;

(6) Test samples.

Quantity of samples to be submitted:

a. 24 battery samples (6 more spare samples can be submitted);

b. 37 battery pack samples (3 more spare samples can be submitted);

C. At least 12 power bank samples.
