Obeautycase is the global brand, and the sample in this report was submitted by its domestic brand OBOX for QB/T 2155-2018 testing.
When global beauty brands source a trolley makeup case from China, the challenge is not only finding a supplier. The real issue is determining whether the product can perform reliably in shipping, travel, and long-term daily use.
For B2B buyers, appearance alone is not enough. A trolley makeup case must pass mechanical durability and material safety checks before it can be trusted for retail, salon, or private label programs.
That is why the OBOX sample was tested under QB/T 2155-2018 with PTC report number PTC25110301801C-CN01.
What Is QB/T 2155-2018?
QB/T 2155-2018 is the Chinese industrial standard for travelling cases and trolley bags. It covers classification, requirements, test methods, inspection rules, marking, labeling, packaging, transportation, and storage.
This standard is especially relevant for a trolley makeup case because these products often contain fragile cosmetics, mirrors, tools, and other high-value items. If the structure, handle, or wheels fail during transport, the entire case becomes a liability for the buyer.
What Was Tested in the PTC Report?
PTC evaluated the OBOX sample across multiple performance areas, including pull rod durability, wheel travel performance, impact resistance, and chemical safety.
The report shows that the sample was tested on 2025-11-03 and issued on 2025-11-12 under report number PTC25110301801C-CN01.
| Test Item | Condition | Result |
|---|---|---|
| Pull rod fatigue | 3,000 cycles | Passed |
| Wheel abrasion | 16 kg load | 0.3 mm |
| Free formaldehyde | GB/T 2912.1-2009 | N.D. |
| Restricted aromatic amines | 24 substances | N.D. |
Pull Rod Fatigue Performance
One of the most important tests in this report was the pull rod fatigue test.
According to the report, the sample completed 3,000 cycles of pull rod testing.
That matters because a telescopic handle is one of the most frequently used parts of a trolley makeup case. If the handle loosens, jams, or deforms, the product quickly loses value for professional users. A successful result here suggests the case is built for repeated commercial use.
Wheel Travel and Abrasion Performance
Under a load of 16 kg, the wheel abrasion measured only 0.3 mm.
That is important for buyers because the wheel system directly affects how easily the trolley makeup case can move through airports, salons, warehouses, and trade show environments. Lower abrasion generally indicates stronger wheel durability and better long-term travel performance.
This result also connects closely with our article explaining the working principle of silent wheels.
Chemical Safety Results
The report also includes chemical testing for the internal materials.
For free formaldehyde, the result was N.D. under the GB/T 2912.1-2009 method.
For all 24 restricted aromatic amines, the report also shows N.D. results.
For global buyers, that is important because material safety affects compliance confidence, user trust, and product suitability for international markets. It also helps support safer sourcing decisions for cosmetic storage products used in close contact with beauty tools and personal items.
Why These Results Matter
This report gives buyers more than just technical data. It provides a practical picture of how the trolley makeup case is likely to perform in real business use.
If a trolley makeup case can pass a pull rod fatigue test, show only 0.3 mm wheel abrasion under load, and return N.D. on key chemical tests, it becomes easier for sourcing teams to evaluate it as a serious professional product rather than a basic consumer item.
For brands, distributors, and procurement teams, this kind of evidence reduces sourcing risk and increases confidence in product consistency.
About the Product Sample
The report sample is identified as an OBOX product, which makes the testing results directly relevant to this trolley makeup case.

This makes the article useful both as a technical reference and as a trust-building page for Obeautycase.
FAQ
What does N.D. mean?
N.D. means “Not Detected,” which indicates that the tested substance was not found above the method’s detection limit in the sample.
Why is 0.3 mm important?
0.3 mm wheel abrasion under a 16 kg load shows strong wheel durability and low wear during travel use, which is important for long-term performance in a trolley makeup case.
Why does QB/T 2155-2018 matter for a trolley makeup case?
Because it is a recognized Chinese industrial standard for travelling cases and trolley bags, covering structural and performance requirements that are relevant to a trolley makeup case.
Closing Thoughts
QB/T 2155-2018 testing is not just about compliance paperwork. For international buyers, it is a way to verify that a trolley makeup case can handle real transport stress while maintaining safety and durability.
