Guidelines For Listing 3C Products

Key Points

• Use the recommended title structure.
• Fill in all key attributes accurately.
• Use clear, authentic product images.
• Ensure the detail page includes all required sections.
• Avoid absolute claims and misleading information.

• Mobile Phones/Tablets/Computers and Accessories
• Audio devices (headphones/speakers/microphones)
• Smart wearables (bands/watches)
• Household small appliances (for example, routers, set-top boxes, power adapters, chargers, data cables, power banks)
• Other 3C digital electronic products and accessories

Product Title

[Brand] + Core Category + Key Specifications/Parameters + Applicable Scenarios/Devices + Unique Selling Points
Example:
[Apple] iPhone 15 5G Smartphone 256GB, Unicom Network, Dual SIM Dual Standby.

Best Practices

• Brand Name: If a product has a brand, it shall be indicated and be consistent with the brand field in the attributes.
• Core category terms:
  • Mobile phones
  • Tablets
  • Routers
  • Bluetooth earphones
  • Power banks
  • Data cables
• Key specification parameters: Capacity (128GB), power (65W), interface type (USB-C), network standard (5G), size (27-inch monitor).
• Applicable devices: "Compatible with iPhone/Android/laptop" (especially important for accessory products).
• Selling points and features: "Fast charging, noise reduction, Wi-Fi 6, 4K, 120Hz".

What to Avoid

• Absolute terms: "Number one", "Best in the industry", "Lifetime warranty against damage", "Never overheat", "100% non-heating". Using prohibited absolute terms may result in your product listing being de-boosted or removed.
• Unrealistic or absolute battery and charging claims, including ‘never runs out of power,’ ‘one-second full charge,’ ‘instant full charge,’ or extreme endurance claims that do not state realistic usage conditions.
• Obvious false or unreasonable efficacy: "Signal never drops", "Never runs out of power", "Never crashes".
• Brand/Model/Specification inconsistent with the actual situation: Ordinary chargers are labeled as "original official chargers", or incorrect memory/power ratings are marked.
• Unauthorized or infringing "XX lookalike" or "imitation of a certain brand".

Product Attribute

• Attributes are an important basis for buyers to search for products. Providing inaccurate attributes may lead to product removal. The following are the general attributes of 3C products:
• Brand:
  • Should be consistent with the brand information in the title and details.
  • Avoid impersonating well-known brands or using misspellings that are confusingly similar to other brands (such as differing by 1 letter).
• Model:
  • Use official models, such as "iPhone 15", "WH-1000XM5", "RT-AX86U"
  • Self-developed products should have a unified internal naming system to avoid multiple confusing model numbers for the same product.
• Color/Appearance: Use standard color names (Black / White / Silver / Blue), and avoid using non-standard color names such as "Popular Color" as official attributes.
• Compatible Devices:
  • Accurately fill in the applicable devices, especially for accessory products, such as "this phone case is suitable for iPhone 15/16/17";
  • Specify the applicable device rather than the applicable brand. For example, avoid describing the product as "this phone case is suitable for Apple" in this case.
• Size/Dimensions: length × width × height / diameter / thickness.
• Key technical attributes (depending on the product category).
• Mobile phones/tablets: Memory (RAM - Random Access Memory), Storage (ROM - Read-Only Memory), Screen size, resolution, Number of SIM cards, Battery capacity.
• Headphones/Speakers: Connection method (wired/Bluetooth), interface type, whether it supports noise reduction, whether it has a microphone.
• Projector: Resolution, brightness, size, interface type.
• Monitor: size, resolution (1080p/2K/4K), refresh rate, panel type (such as IPS (In-Plane Switching) for better color, TN for faster response, or VA for high contrast), interface type (for example, HDMI, DP).
• Charger/Data Cable/Power Bank: Include rated power, voltage/current range, capacity (mAh), interface type (for example, USB-A, USB-C, Lightning), and supported fast charging protocols (for example, Power Delivery (PD), Quick Charge (QC)).
• Handheld game console: screen size / resolution, battery capacity, supported systems (Android / Windows / proprietary system).
• Smartwatch: screen size, resolution, touch type (full touch / touch + physical buttons), battery capacity/endurance.
• USB Flash Drive / External Hard Drive / Solid State Drive (SSD) External Hard Drive: Capacity (for example, 32GB, 64GB, 1TB), Interface Type (for example, USB-A, USB-C, Dual Interface), and Enclosure Material (for example, Metal, Plastic).
• Router: Frequency band (2.4G/5G), speed, number of antennas.

Best Practices

• Information is true and accurate, without false labeling:
  • Avoid labelling 4G phones as 5G
  • Avoid labeling a 4600mAh battery as 5000mAh
  • Avoid writing the 18W charger as a 65W fast charger
• Key attributes should be filled in (even those marked as "optional" by the platform):
  • Power supply/battery products shall indicate capacity, input/output parameters.
  • Storage classes shall indicate capacity and actual available capacity specifications.
• Consistent with the title and details:
  • If the title claims "256GB", the attribute must be 256GB to avoid inconsistency.
  • Information such as color, model, and interface type should avoid self-contradiction.

Product Images

Best Practices for Main Image

• The main body of the product should be centered, and the main body should occupy the main area of the image (approximately ≥80%).
• The main image should display the core product actually being sold, and should not use only a concept image to replace the physical product.

Best Practices for Other Images

• Physical object images from different angles: front/back/side/top/bottom.
• Close-ups of key interfaces/buttons: interface types (USB-C/HDMI), button layout, SIM card slot.
• For smaller products (such as USB flash drives and data cables), handheld or proportional objects can be used to demonstrate their size. Avoid using PS or AI-generated images to alter the true proportions.
• Screen category: When displaying the screen's visual effects, it should ensure authenticity and not mislead through exaggerated rendering (such as extremely narrow borders or extremely unrealistic brightness).
• Scenario Usage Images:
  • Such as earphone wearing demonstrations, routers placed in homes, usage of laptops connected to monitors,
  • If other expensive equipment or accessories appear in the image, it should be stated whether they are included in the sale or merely for illustration.
• Size Specification: Use wireframes/annotations to show product dimensions (length, width, height), cable length, weight. Use local units of measurement (for example, use inches instead of centimeters).

Practices to Avoid

• Avoid showing other products that are unrelated to the item for sale or may mislead consumers. For example, do not show a set of items (like headphones, a charger, and a case) if only the headphones are being sold.
• Images that are clearly inconsistent with the brand/model (for example, using pictures of the latest model to sell an older version). Using misleading images can lead to product removal.
• Using false comparison images, such as exaggerating the comparison between "before and after signal enhancement" and using fake signal icons.
• The image contains dangerous usage methods (for example, battery exposed to high temperature/near a fire source).

Product Detail Page

Basic parameters and specification information of the product (required)

• Brand, model, color, weight, material, main technical parameters.

Battery, Charging, and Performance Claims

• Avoid absolute or unrealistic statements such as “never runs out of power,” “one-second full charge,” or similar claims that overstate actual product performance.
• If you mention battery life, charging speed, power, capacity, cooling or heating, noise reduction, audio or video quality, or other core performance features, make sure the information reflects the product’s real capabilities and is described consistently throughout the listing.
• If excessive customer feedback shows actual battery life materially differs from the PDP claim, or if the product cannot perform a PDP-stated function such as powering on, connecting, working, or outputting a signal. Appeals for function-related removals may require testing reports or equivalent evidence proving the product works as claimed.

Functional features and usage scenarios (required)

• Function Introduction: Such as "Supports dual-band Wi-Fi 2.4G + 5G", "Supports Power Delivery (PD) 3.0 / Quick Charge (QC) 3.0 charging protocols", "Active Noise Cancellation (ANC)".
• Usage scenarios: work/gaming/travel/home theater/online meetings;
• Experience descriptions: such as "stable connection, low latency (based on reasonable testing)", "ergonomic wearing, comfortable even for long-term use".

Compatibility Description (Applicable Devices, Systems, Protocols) (Required)

• Applicable device models/systems/brands:
  • for example, "Compatible with iPhone 12 and above / MacBook series (USB-C interface)".
  • Avoid writing "suitable for all mobile phones" in a general way, unless it truly meets the criteria and has technical basis.
• Restriction Description:
  • When certain features are only available for some models, such as "fast charging is only available for devices supporting the PD protocol".
  • Reminders should be provided for the results of incompatible devices, such as "Connecting a non-PD device will only operate at normal charging power".
• For phone cases and auto/motorcycle accessories, compatibility claims must match the actual item. Excessive customer feedback showing misaligned cutouts, blocked ports, wrong model fit, or mismatched mounting positions may lead to product removal, unless the issue is attributable to a wrong SKU purchase or a vague complaint without detail.

Instructions for Use and Packing List (Required)

• Instructions for Use:
  • Include initial usage instructions, such as first charging time, power-on pairing steps, function operations, and Application (APP) download methods.
  • Frequently Asked Questions (Q&A) (for example, "What to do when unable to connect").
• Packing List: The packing list must match the contents of the physical package. A typical list includes:\n- 1 main unit\n- 1 data cable\n- 1 user manual\n- 1 warranty card

Safety Notice (recommended to fill in)

• Batteries, chargers, power banks, and similar items shall specify usage scenario restrictions:
  • Avoid high temperature/humidity environments
  • Do not disassemble/throw into fire
  • This product is not recommended for use by children without supervision
• For usage methods that may pose risks, clear warnings should be provided:
  • If long-term use causes the product to heat up, provide a notice such as "it is recommended not to use continuously for more than XX hours".
  • Volume health tips for long-term headphone use
  • Power limit instructions for external devices (to avoid overload)

After-sales Instructions (recommended to fill in)

• Specify the warranty period: such as "12 months warranty for the main unit, 6 months warranty for accessories".
• Warranty Scope: Are human damage, liquid immersion, modification, and disassembly covered by the warranty?
• Possible costs: If there are additional costs for after-sales service, it is necessary to explain whether the after-sales service will incur costs and the cost standards. For example, "The main unit is under warranty for 12 months, and the repair cost after 12 months is XX.".
