For an electronic device to become a refurbished product, it goes through a rigorous process designed to ensure its quality, reliability, and performance. Each device undergoes a series of functional tests, is repaired if necessary, and is then thoroughly cleaned before receiving an aesthetic assessment, also known as grading.
At Dipli, every device systematically goes through around 40-point quality check before undergoing a visual inspection and being assigned a grade. This entire process is carried out by our certified refurbishment partners in accordance with strict quality specifications. This methodology ensures that every refurbished device meets high quality standards and delivers a reliable, long-lasting experience for the end user.
💡 In this article, we take a closer look at Dipli's refurbished offers to help you better understand the meaning of each grade and choose the refurbished device that best suits your needs with confidence.
What is a refurbished grade?
In the refurbished electronics industry, grades are used exclusively to assess the aesthetic condition of a device returned to the market. They do not reflect its technical performance or functionality, as these are verified beforehand through a series of rigorous tests and, where necessary, repairs.
In practice, a grade only indicates the device's level of visible wear, such as micro-scratches, minor scratches, or marks on the screen and casing, or, on the other hand, a condition that is close to new. This grading system makes it possible to distinguish between two devices that are technically identical but differ in appearance, which explains the price differences between refurbished models.
At Dipli, we’ve developed a grading system based on a strict quality framework. This internal standard ensures:
- Consistent quality, regardless of stock,
- Reliable traceability,
- Grading consistency across all our certified refurbishing partners.
We distinguish 5 grading levels in our range of refurbished electronic products:
- New,
- Certified Pre-Owned (CPO),
- Grade A,
- Grade B,
- Grade C.
Refurbished grades at Dipli: the guide
1. New product
These products have never been activated or used. They are in their original box.

2. CPO
The CPO (Certified Pre-Owned) products have been refurbished with original parts. The aesthetic condition is equal to "new".

3. Grade A
These products are in excellent condition, and they represent the highest grade possible in terms of device refurbishment. The product is flawless: there are no signs of wear. A minor scratch may be present on the casing, but it will be barely visible to the naked eye.

4. Grade B
These products have one or several light scratches on the casing or screen, barely visible at a distance of more than 20 cm. A small mark or multiple small scratches on the frame or back cover may be present. The overall condition is good.

5. Grade C
These products have pronounced signs of wear on the frame, back cover, and screen. This grade offers an attractive entry-level price and is suitable for the “Fair Condition” grades on B2C marketplaces. Our advice: resell this product with a protective case for a winning combination!

What are the functionality levels and packaging options for a refurbished device?
1. Functionality levels: Premium and Used
All devices processed by our partners undergo secure data erasure using specialized software, followed by a comprehensive series of technical tests that meet Dipli's quality requirements. On average, more than 40 quality checkpoints are carried out to verify that every device is fully functional before it is placed back on the market.
We distinguish two levels of functionality for our refurbished products:

Please note:
- Premium: every product is 100% tested and fully functional. This means you can purchase a refurbished device with confidence, knowing it delivers quality equivalent to a new product.
- Used: this corresponds to the basic testing level. The battery of each product is not necessarily tested, which means we cannot guarantee a minimum battery capacity or a maximum number of charge cycles for these devices.
2. Packaging
Once the aesthetic grade and functionality level have been determined, the device is ready for shipment. To meet the diverse needs of businesses and their employees, Dipli offers several packaging options designed to combine protection and practicality.
Depending on your project and specific requirements, you can choose from the following three packaging options:

Please note:
- All accessories provided with the products are new and compatible.
- All individual boxes are neutral (white or brown).
- Basic: you will receive the device on its own, with no additional accessories. Perfect for those who already have compatible accessories or prefer to purchase them separately.
- Cable: you will receive the refurbished device with a certified EU and ROHS charging cable. Cable types may vary depending on the device and availability, but they are always high-quality and designed to support fast and efficient charging.
- Full Pack: you will receive the refurbished device with a charging cable and an individual box. Ideal for a complete and ready-to-use purchase experience.
