Which charger products correspond to pse round and diamond shapes respectively?
Japan's "electrical appliances and materials safety act" classifies electrical appliances into two categories: "designated electrical appliances" and "non-designated electrical appliances", corresponding to different pse marks:
| Comparison item | Diamond pse (specific electrical supplies) | Round pse (non-specific electrical supplies) |
|---|---|---|
| Applicable products | Power adapter, charger body (with transformer function) | Usb charging cable, accessories without transformer function |
| Risk level | Higher voltage, involving voltage conversion and insulation safety | Low voltage, no high-voltage conversion required |
| Certification requirements | Requires review and certification by a third-party certification agency (such as jet, tüv, etc.) | The manufacturer can make a self-declaration and keep technical documents |
| Logo style | Pse marked in diamond frame | Marked pse in a circular frame |
| Typical products | Mobile phone fast charging head, pd charger, notebook power adapter | Usb data cable, charging base, conversion plug |
For cross-border e-commerce sellers, fast-charging mobile phone heads (such as pd20w/30w chargers) usually belong to the diamond-shaped pse range, while matching usb cables are suitable for round pse.When selecting products, you need to confirm the compliance status of the two types of products separately.
What technical documents are required for pse certification of chargers exported to japan?
Regardless of whether it is a round or diamond-shaped pse, exporters need to prepare the following core documents for customs inspection and platform review:
1.product test report: issued by a qualified laboratory, covering electrical safety (voltage resistance, insulation, temperature rise) and emc (electromagnetic compatibility) test items. 2.technical construction book: including circuit diagram, component list, insulation structure description, key component certification information. 3.japanese instruction manual: must include security warnings, rated parameters, manufacturer/importer information. 4.pse declaration of conformity (round pse) or certification certificate (diamond pse): proves that the product has passed the corresponding compliance procedures. 5.importer information filing: japan requires domestic importers to assume product safety responsibilities. cross-border sellers need to confirm that the japanese importer has completed the filing.
note: pse certification itself does not distinguish between "export" and "domestic sales", as long as it is sold in the japanese market.Some sellers mistakenly believe that round pses do not require testing. in fact, although round pses are self-declared, technical documents and test reports must still be kept complete. otherwise, if they cannot provide evidence during random inspections, they will face the risk of being removed from the shelves or fined.
When selecting products on 1688, how do i verify the pse compliance status of chargers?
With shenzhen qida technology as an example, the store has put on the shelves a variety of cross-border adapted chargers, including [cross-border pd30w gallium nitride fast charging charger] (https://detail.1688.com/offer/993072482880.html) and us standard fcc pd12w charging head and other products.When selecting products on the 1688 platform, it is recommended to verify pse compliance according to the following steps:
| Verification steps | Specific operations | Precautions |
|---|---|---|
| View product details page | Confirm whether the pse certification information and certificate number are marked | The page markings are only preliminary signals and need further verification. |
| Ask the supplier for the certificate | Request for original pse certification certificate (diamond shape) or declaration of conformity (round shape) | Confirm that the certificate subject matches the supplier/manufacturer. |
| Check the scope of the test report. | Check if the inspection report covers the complete model and specifications of the target product | Different power models in the same series may require independent testing |
| Confirm importer registration | Ask the supplier if they already have a japanese importer on file for customs clearance. | Products without importer registration cannot be cleared through customs normally |
| Small order verification | Place a small batch order first, and after receiving the actual product, check the consistency of the nameplate pse mark and certificate. | Subject to the actual nameplate and certificate, the information on this page is for reference only. |
key reminder: the certification markings, price grids, inventory and service labels on the 1688 product page are dynamic information. please refer to the real-time page and the latest certificates provided by the supplier.Before placing an order, be sure to confirm the validity and scope of the pse certificate through an inquiry.
Can qidasheng's cross-border chargers be used directly in the japanese market?
According to public information, shenzhen qidaseng network technology co., ltd. part of the products have 3c certification (china), and have sgs certification records (status is displayed as init).However, for japanese pse certification, please pay attention to the following boundaries:
- 3c certification ≠ pse certification: china 3c certification is only applicable to the chinese market and cannot replace japanese pse.Chargers exported to japan need to obtain pse compliance separately.
- sgs certification status needs to be verified: public information shows that the certification status is init. the specific certification type, scope and validity period need to be confirmed with the supplier for the latest status. cross-border compliant products can serve as a foundational selection: this store already carries us fcc and pd fast charging product lines, indicating export compliance capabilities. however, each product's specific certifications for the target market still need to be individually verified.
suggestion: after including qidasen's cross-border chargers in the candidate pool, request suppliers via 1688 inquiries to explicitly provide pse certification or demonstrate their willingness and ability to obtain pse certification.If the supplier does not have pse yet, you can evaluate whether they are willing to jointly promote certification based on the current order volume.
When exporting chargers to japan, what else besides pse certification should i be aware of?
Pse certification is the core entry requirement for the japanese market, but it is not the only compliance point:
- plug standard: japan uses type a plug (two flat pins), voltage 100v/50-60hz.The charger needs to be adapted to japanese socket specifications, or use a compliant conversion plug.
- voltage adaptation: japan's voltage is 100v, which is different from china's 220v.The charger must support 100-240v wide voltage input, otherwise it may damage the device or cause security risks.
- product label: the japanese market requires that the product nameplate be marked with the pse mark, rated parameters, manufacturer/importer name (japanese), and the label language and content must comply with jis standards.
- rohsenvironmental-friendly: some japanese buyers and platforms require a rohs compliance declaration to limit the content of harmful substances such as lead and cadmium.
- intellectual property: avoid using unauthorized trademarks of fast charging protocols (such as supercharge, vooc, etc.). the appearance of the product must not infringe on japanese registered design patents.
