Detailed Analysis
1. Company Strength
Basis
- Factory location: Guangdong, China
- Factory area: 3,100+㎡
- Employees: 60+ staff
- Verified supplier: True
Elaboration
Granbo Technology Industrial Shenzhen Co., Ltd. operates with a factory scale of over 3,100㎡ and more than 60 employees. This indicates a functioning manufacturing setup with basic-to-moderate production capacity. The verified supplier status provides additional credibility regarding its operational presence, although no detailed production line count, annual output, machinery list, or factory audit report details were provided.
Scoring Rationale
The company does not appear to be a large-scale industrial supplier based on the available factory size and workforce data, but it has sufficient physical infrastructure and staffing to support stable production for ultrasonic cleaner products. Verified supplier status strengthens confidence in its legitimacy. However, the absence of deeper factory capacity indicators prevents a higher score.
Final Score
15 / 20
2. Platform & Compliance Credibility
Basis
- Gold Supplier: True
- Gold Supplier duration: 8 years
- Trade Assurance: True
- Certification / platform tags: Warranty available, Finished Product Inspection, ODM service available, Full customization
Elaboration
The supplier has maintained Gold Supplier status for 8 years and supports Trade Assurance, which provides a meaningful platform-level trust signal. The listed platform tags also indicate several commercially important capabilities, including warranty availability, product inspection, ODM service, and customization.
Scoring Rationale
An 8-year Gold Supplier history, Trade Assurance support, and multiple credibility-related platform tags form a strong platform compliance profile. While the provided data does not include third-party management system certifications such as ISO or specific product compliance certificates, the -side credibility indicators are relatively complete.
Final Score
18 / 20
3. Business Performance
Basis
- Orders in past 6 months: 100+
- Transaction value in past 6 months: ¥1.352 million+
- Store rating: 4.7
- Reviews: 40+
Elaboration
The supplier has recorded more than 100 orders and over ¥1.352 million in transaction value during the past six months. This suggests an active commercial presence rather than an inactive listing. A 4.7 store rating with 40+ reviews indicates generally positive buyer feedback, although the review volume is not high enough to be considered large-scale validation.
Scoring Rationale
The business data supports a stable medium-level transaction profile. The order count and transaction amount show meaningful market activity, and the 4.7 rating is favorable. However, the review base remains moderate, limiting the strength of customer validation compared with suppliers that have substantially higher review volumes and transaction history.
Final Score
16 / 20
4. Service Capability
Basis
- Response time: ≤2h
- Full Customization: Available
- ODM service: Available
Elaboration
The supplier demonstrates acceptable communication responsiveness, with a response time of no more than two hours. It also supports Full Customization and ODM service, which indicates the ability to handle product adaptation or buyer-specific requirements within the ultrasonic cleaner category.
Scoring Rationale
The response time is good but does not meet the highest benchmark of ≤1 hour. The presence of Full Customization and ODM service strengthens service capability, especially for buyers requiring tailored product specifications. Based on the data, service capability is solid but not at the top tier.
Final Score
8 / 10
5. Delivery Performance
Basis
- On-time dispatch rate: 93.4%
Elaboration
A 93.4% on-time dispatch rate indicates a strong delivery performance profile. This suggests the supplier generally manages order processing and shipment timing effectively.
Scoring Rationale
According to the scoring framework, an on-time dispatch rate above 90% qualifies for 9–10 points. The supplier’s 93.4% rate is clearly above the threshold, supporting a high delivery score. Since no additional logistics data or late-shipment breakdown was provided, the score remains strong but not perfect.
Final Score
9 / 10
6. Quality & Customer Feedback
Basis
- Store rating: 4.7
- Reviews: 40+
- Finished Product Inspection: Available
- Verified supplier: True
Elaboration
The supplier has a 4.7 store rating and more than 40 reviews, suggesting generally positive customer feedback. Finished Product Inspection is listed, which supports quality control before shipment. Verified supplier status further supports baseline trust in the company’s operational legitimacy.
Scoring Rationale
Quality-related indicators are positive, especially the high store rating and Finished Product Inspection tag. However, the number of reviews is moderate rather than extensive, and no detailed product defect rate, inspection report, quality management certification, or customer complaint data was provided. Therefore, the supplier shows good but not fully comprehensive quality assurance evidence.
Final Score
16 / 20
Total Score
82 / 100
Procurement Recommendation
Cooperation is recommended with controlled qualification steps. Granbo Technology Industrial Shenzhen Co., Ltd. appears suitable for buyers sourcing ultrasonic cleaner products, especially those needing low MOQ orders, ODM support, Full Customization, and Trade Assurance protection. The supplier is most appropriate for small to medium-volume buyers, product testers, distributors, and customized ultrasonic cleaner procurement projects.
Main risks include limited visibility into detailed production capacity, absence of provided third-party product certifications, moderate review volume, and insufficient data on defect rates or after-sales performance. Growth potential is positive due to its 8-year Gold Supplier status, verified supplier profile, customization capability, and stable recent transaction performance. For larger procurement programs, sample validation, inspection requirements, and specification confirmation are recommended before bulk ordering.
