Guangzhou Quanju Ozone Technology Co., Ltd. Supplier Evaluation

Executive Summary

Guangzhou Quanju Ozone Technology Co., Ltd. is a China-based supplier located in Guangdong, with a reported factory area of over 800㎡ and more than 30 staff. The company appears to operate as a small-to-medium production supplier focused on ozone generators and oxygen generator-related products, with listed products covering portable, car-use, commercial, kitchen, food factory, and industrial oxygen generator applications. Its platform credibility is relatively strong, supported by 14 years as an Gold Supplier, Trade Assurance availability, verified supplier status, and listed service/quality tags including Finished Product Inspection, ODM service, Full Customization, and Warranty available. Business performance is moderate, with 30+ orders and CN¥473.2K+ transaction value over the past six months, alongside a 4.6 store rating and 10+ reviews. The supplier is most suitable for buyers seeking low-MOQ ozone generator sourcing, customized product support, and verified transaction protection. Key limitations include modest factory scale and limited review volume.

Detailed Analysis

1. Company Strength

Basis:
- Factory location: Guangdong, China
- Factory area: 800+㎡
- Employees: 30+ staff
- Verified supplier: True

Elaboration:
The supplier has a clearly stated physical production base with over 800㎡ of factory area and more than 30 employees. This indicates basic in-house operational capacity rather than a purely trading-oriented profile. The verified supplier status adds credibility to the existence and operating structure of the company, although no detailed factory audit report, production line count, annual capacity, or specific factory management certification is provided.

Scoring Rationale:
The company demonstrates small-to-medium production capability. Its factory size and workforce are sufficient for basic manufacturing and order fulfillment, especially for low-MOQ and customized ozone generator products. However, the available scale data does not support classification as a large-scale supply chain manufacturer. The lack of detailed production capacity, equipment list, or factory certification limits the score.

Final Score: 13 / 20

2. Platform & Compliance Credibility

Basis:
- Gold Supplier: True
- Gold Supplier duration: 14 years
- Trade Assurance: True
- Verified supplier: True
- Listed tags: Warranty available, Finished Product Inspection, ODM service available, Full customization

Elaboration:
The supplier has a long-standing presence, with 14 years as a Gold Supplier. Trade Assurance availability provides transaction protection for buyers, while verified supplier status strengthens platform-level credibility. The listed tags show a relatively complete platform profile, including warranty, finished product inspection, ODM service, and full customization.

Scoring Rationale:
This is one of the supplier’s strongest areas. A 14-year Gold Supplier history is a meaningful platform credibility indicator, and Trade Assurance plus supplier verification creates a strong compliance and transaction security foundation. While the data does not include third-party product certifications or detailed compliance certificates, the platform credibility signals are complete and long-established.

Final Score: 19 / 20

3. Business Performance

Basis:
- Past 6-month orders: 30+
- Past 6-month transaction value: CN¥473.2K+
- Store rating: 4.6
- Reviews: 10+

Elaboration:
The supplier has generated visible recent platform transactions, with more than 30 orders and over CN¥473.2K in transaction value during the past six months. The average transaction value appears meaningful relative to the listed product prices, especially considering several products are industrial or commercial-use machines. The store rating of 4.6 is positive, though the review count remains limited at 10+.

Scoring Rationale:
The supplier shows verified commercial activity and a moderate transaction base. The order count and transaction value suggest ongoing demand, but the scale is not high enough to classify the supplier as a high-volume marketplace performer. The 4.6 rating is acceptable, yet the relatively small review base reduces statistical confidence in customer satisfaction consistency.

Final Score: 15 / 20

4. Service Capability

Basis:
- Response time: ≤3h
- Full customization: Listed
- ODM service available: Listed

Elaboration:
The supplier provides a response time of within three hours, which indicates normal communication efficiency but not the fastest service level. Full customization and ODM service availability suggest the supplier can support customized requirements rather than only standard product resale. However, no data is provided on design team size, engineering support process, sample lead time, or customization case history.

Scoring Rationale:
The supplier demonstrates solid service capability through customization and ODM tags, making it suitable for buyers with product modification needs. The response speed is reasonable but does not meet the highest benchmark of one hour or less. Because customization capability is listed but not supported by detailed project examples, the score remains in the upper-middle range rather than the top tier.

Final Score: 8 / 10

5. Delivery Performance

Basis:
- On-time dispatch rate: 100.0%

Elaboration:
The supplier reports a 100.0% on-time dispatch rate, which is the strongest possible delivery indicator within the available dataset. This suggests reliable fulfillment performance for recorded platform transactions. No additional information is provided regarding average lead time, logistics channels, or performance under bulk order conditions.

Scoring Rationale:
Based strictly on the provided on-time dispatch rate, the supplier qualifies for the highest delivery performance range. The only limitation is that the dataset does not disclose order complexity or volume distribution behind the 100.0% rate, but the metric itself is clear and directly supports a top score.

Final Score: 10 / 10

6. Quality & Customer Feedback

Basis:
- Store rating: 4.6
- Reviews: 10+
- Finished Product Inspection: Listed
- Verified supplier: True
- Warranty available: Listed

Elaboration:
The supplier has a positive store rating of 4.6 and provides listed quality-related assurances including Finished Product Inspection and warranty availability. Verified supplier status further supports baseline trust in the company profile. However, the review count is only 10+, which limits the depth of customer feedback available for quality validation.

Scoring Rationale:
The quality framework appears reasonably supported by Finished Product Inspection and warranty availability, and the rating is good. However, the limited number of reviews prevents a stronger conclusion about long-term product consistency and after-sales satisfaction. The supplier therefore fits the “good rating with basic quality assurance” level, rather than the “high rating with large review base” category.

Final Score: 16 / 20

Total Score

81 / 100

Procurement Recommendation

Cooperation is recommended with controlled order validation. Guangzhou Quanju Ozone Technology Co., Ltd. is suitable for small-to-medium buyers, distributors, customized ozone generator purchasers, and buyers requiring low MOQ sourcing with Trade Assurance protection. Its main strengths are long operating history, verified supplier status, Trade Assurance support, full customization/ODM availability, 100.0% on-time dispatch, and visible recent transaction activity.

Main risks include modest factory scale, limited review volume, and insufficient data on production capacity, product certifications, detailed factory audit results, and large-volume fulfillment capability. The supplier has growth potential for customized and low-to-medium volume procurement, but buyers should request product compliance documents, inspection reports, sample validation, and production lead-time confirmation before placing larger orders.
