Obeautycase serves international markets, while OBOX is the company’s domestic-market brand. The sample identified in this report was submitted under 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 should be evaluated through mechanical durability and material safety checks before it is approved 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.
The results discussed below were obtained from the OBOX sample identified in PTC report PTC25110301801C-CN01. Because OBOX and Obeautycase are operated by the same company, and some Obeautycase products may use comparable materials, structures and manufacturing processes, the findings can provide a useful technical reference when evaluating similar configurations. Model-specific performance should still be confirmed through the approved sample and agreed inspection criteria.
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. For this tested sample, completing 3,000 cycles provides documented evidence of repeated handle use under the report conditions. Products using comparable handle structures may use this result as a technical reference, while the final model should still be confirmed during sample approval.
Wheel Travel and Abrasion Performance
In the tested OBOX sample, wheel abrasion measured 0.3 mm under a load of 16 kg.
The wheel system directly affects mobility through airports, salons, warehouses and trade-show environments. Lower abrasion can be a useful durability indicator, but meaningful comparisons between models require the same test conditions, load and wheel specification.
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 documented reference data for evaluating how the tested construction performed under the stated conditions.
In the tested OBOX sample, the report recorded completion of the pull-rod fatigue test, 0.3 mm of wheel abrasion under a 16 kg load, and N.D. findings for the listed chemical substances. These results provide useful technical reference points for evaluating Obeautycase products with comparable materials, structures and manufacturing processes. Actual performance may vary with the model, component specifications and production configuration.
For brands, distributors and procurement teams, this evidence supports more informed sample review and specification decisions.
About the Product Sample
The report directly documents the OBOX sample identified in PTC25110301801C-CN01. OBOX is our domestic-market brand, while Obeautycase serves international markets. Because products developed for the two brands may use comparable materials, components, structures and manufacturing processes, the findings may also serve as a technical reference when evaluating similar Obeautycase configurations. They should not be presented as separate model-specific certification unless the relevant model is covered by applicable test documentation. Buyers should combine the report with durability checks on the approved physical sample before bulk production.

This context helps international buyers distinguish between documented sample evidence and model-specific approval.
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.
What does the 0.3 mm wheel-abrasion result mean?
In PTC25110301801C-CN01, the tested OBOX sample recorded 0.3 mm of wheel abrasion under a 16 kg load. This result provides a useful reference for Obeautycase products using comparable wheel materials, structures and manufacturing processes. The final production model should still be evaluated against the buyer’s agreed requirements.
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
The QB/T 2155-2018 report provides documented mechanical and chemical test results for the identified OBOX trolley makeup case sample. The findings can help international buyers evaluate Obeautycase configurations that use comparable materials, structures and manufacturing processes. Final model performance should still be confirmed through the approved sample and agreed inspection criteria.
