Yangzhou Dongtai Solar Energy Co., Ltd. Supplier Evaluation

Executive Summary

Yangzhou Dongtai Solar Energy Co., Ltd. is a China-based supplier located in Jiangsu, with a reported factory area of over 3,000㎡ and more than 90 staff. The company appears to focus on rechargeable gel batteries, lead-acid batteries, and related energy-storage products, with low minimum order quantities ranging from 2 to 5 units/pieces across the listed products. Its platform credibility is relatively strong, supported by 10 years as an Gold Supplier, Trade Assurance availability, supplier verification, and listed service/quality tags including Finished Product Inspection and Full Customization. Commercial performance is moderate, with 20+ orders and CN¥338K+ transaction value in the past six months, but the store rating of 3.8 and only 8 reviews limit confidence in customer satisfaction validation. Overall, this supplier is suitable for buyers seeking small-to-medium batch procurement, sample orders, or customizable battery products, while larger buyers should conduct additional quality and factory due diligence before scaling orders.

Detailed Analysis

1. Company Strength

Basis:
- Factory area: 3,000+㎡
- Employees: 90+ staff
- Verified supplier: True
- Location: Jiangsu, China

Elaboration:
The supplier has a defined physical factory scale and workforce, indicating basic-to-medium manufacturing capacity. A 3,000+㎡ factory and 90+ employees suggest it is not a very large-scale industrial supplier, but it does have an operational production base beyond a small trading-only structure. The verified supplier status provides additional confidence that the company has undergone some level of supplier validation.

Scoring Rationale:
The company demonstrates stable production fundamentals, but the factory size and workforce are more consistent with a small-to-medium manufacturer rather than a large-scale supply-chain operator. The presence of supplier verification improves confidence, but there is insufficient data on production lines, annual capacity, equipment, or factory audit details to justify a top-tier score.

Final Score: 14/20

2. Platform & Compliance Credibility

Basis:
- Gold Supplier: True
- Gold Supplier duration: 10 years
- Trade Assurance: True
- Certification/industry tags: Project solutions, Warranty available, Finished product inspection, Full customization

Elaboration:
The supplier has a strong platform history, with 10 years of Gold Supplier status. Trade Assurance availability also improves buyer protection during transactions. The listed tags show useful commercial and operational capabilities, including customization, warranty availability, and finished product inspection.

Scoring Rationale:
A 10-year Gold Supplier record combined with Trade Assurance and multiple platform tags provides a strong credibility foundation. However, the data does not provide specific third-party management system certifications, product certifications, or detailed audit reports, so the score should remain below the maximum.

Final Score: 18/20

3. Business Performance

Basis:
- Past 6-month orders: 20+
- Past 6-month transaction value: CN¥338K+
- Store rating: 3.8
- Review count: 8

Elaboration:
The supplier has recent transaction activity, showing that buyers have placed orders within the last six months. The transaction value of CN¥338K+ indicates some commercial traction, but the order count and review base remain limited. The store rating of 3.8 is not high and should be treated as a cautionary signal.

Scoring Rationale:
The supplier has measurable sales activity, but the commercial validation is not strong enough to be considered high-performing. Low review volume reduces statistical confidence, and the 3.8 rating suggests customer experience may be inconsistent or insufficiently proven.

Final Score: 12/20

4. Service Capability

Basis:
- Response time: ≤2h
- Full Customization: Listed as available

Elaboration:
A response time within two hours indicates reasonably efficient communication. The Full Customization tag suggests the supplier can support customized product requirements, which is relevant for battery procurement involving specifications such as voltage, capacity, labeling, packaging, or application needs. However, no detailed customization scope is provided.

Scoring Rationale:
The supplier shows good service responsiveness and customization capability, but the response time does not meet the strongest benchmark of ≤1 hour. Since customization is listed but not described in detail, the score is strong but not top-tier.

Final Score: 8/10

5. Delivery Performance

Basis:
- On-time delivery rate: 100.0%

Elaboration:
The reported on-time delivery rate is excellent. A 100.0% rate indicates that, based on the available platform data, the supplier has met delivery commitments consistently.

Scoring Rationale:
According to the scoring standard, an on-time shipment rate above 90% qualifies for 9–10 points. Since the reported rate is 100.0%, the supplier deserves the maximum score in this category.

Final Score: 10/10

6. Quality & Customer Feedback

Basis:
- Store rating: 3.8
- Review count: 8
- Finished Product Inspection: Listed
- Verified supplier: True

Elaboration:
The supplier has some quality assurance support through Finished Product Inspection and verified supplier status. These are positive indicators for basic quality control. However, the customer feedback base is limited, with only 8 reviews, and the rating of 3.8 is moderate rather than strong.

Scoring Rationale:
The presence of Finished Product Inspection supports a baseline quality-control process, but customer feedback does not yet provide strong evidence of consistent satisfaction. The limited number of reviews and moderate rating create quality confidence limitations, especially for buyers considering larger or repeat orders.

Final Score: 14/20

Total Score

76/100

Procurement Recommendation

Cooperation is recommended with caution. Yangzhou Dongtai Solar Energy Co., Ltd. is suitable for buyers seeking small-to-medium volume battery procurement, sample testing, customized orders, or Trade Assurance-supported transactions. Its strongest advantages are long platform history, Trade Assurance, fast response, customization availability, and excellent reported delivery performance.

Main risks include a moderate store rating of 3.8, only 8 customer reviews, and insufficient data on production capacity, product certifications, factory audit depth, and detailed quality-control procedures. For larger orders, buyers should request product test reports, certification documents, warranty terms, production photos/videos, and pre-shipment inspection before scaling procurement. The supplier shows growth potential if it can improve customer feedback volume, rating performance, and provide stronger compliance documentation.
