Shanghai Donglai Air Motive Equipment Co., Ltd. Supplier Evaluation

Executive Summary

Shanghai Donglai Air Motive Equipment Co., Ltd. is a China-based supplier located in Shanghai, offering air compressor-related products including portable diesel air compressors, mobile diesel air compressors, aluminum compressed air pipes, and screw compressor air ends. The supplier shows strong platform credibility, with 18 years as an Gold Supplier, Trade Assurance support, and verified supplier status. Its factory area of 12,000+ m2 indicates a meaningful production footprint, although the reported workforce of 20+ staff suggests a relatively lean operating team. Recent business performance is limited, with 4 orders and CN¥67.6K+ transaction value over the past six months, while customer review data and store rating are unavailable or absent. Delivery performance is a key concern, with an on-time delivery rate of 66.7%. Overall, this supplier may be suitable for buyers seeking low-MOQ air compressor products from a long-established platform supplier, but cautious qualification is recommended before larger or time-sensitive procurement.

Detailed Analysis

1. Company Strength

Basis:
The supplier is located in Shanghai, China, with a reported factory area of 12,000+ m2, 20+ staff, and verified supplier status marked as True.

Elaboration:
The 12,000+ m2 factory area indicates a substantial physical facility, which supports the view that the company has a real operating base and potential production or warehousing capacity. However, the reported workforce of 20+ staff is relatively small compared with the factory size, which may suggest a lean team structure or limited disclosed staffing scale. The verified supplier status provides some additional confidence that the company has passed a form of supplier verification, but no detailed factory audit report, production line count, machinery list, or annual capacity data is provided.

Scoring Rationale:
The supplier demonstrates stronger-than-basic company strength due to its sizable factory area and verified supplier status. However, the limited employee count and lack of disclosed production capacity prevent it from being classified as a large-scale, highly stable supply chain. The profile is more consistent with a medium-sized supplier with a credible physical base but incomplete operational transparency.

Final Score: 15 / 20

2. Platform & Compliance Credibility

Basis:
The supplier is an Gold Supplier for 18 years, supports Trade Assurance, and is marked as a verified supplier. Listed platform labels include “Response time ≤4h” and “On-time delivery 66.7%.”

Elaboration:
An 18-year Gold Supplier record is a strong platform credibility indicator and suggests long-term presence on . Trade Assurance support adds transaction protection for buyers, while verified supplier status further strengthens basic compliance credibility. However, the available certification or industry label information is limited to response time and delivery performance. No independent product certifications, management system certifications, or detailed factory audit certificates are provided in the dataset.

Scoring Rationale:
The supplier has a strong platform trust foundation because of its long Gold Supplier history, Trade Assurance support, and verification status. The score is not full because certification details are incomplete, and the visible labels do not demonstrate a broad compliance or quality certification system.

Final Score: 18 / 20

3. Business Performance

Basis:
In the past six months, the supplier recorded 4 orders and CN¥67.6K+ transaction value. Store rating is not provided, and the number of reviews is 0.

Elaboration:
The transaction data confirms some recent commercial activity, but the order volume is low. A transaction value of CN¥67.6K+ over six months indicates limited but existing buyer engagement. The absence of a store rating and the presence of 0 reviews significantly reduce the visibility of buyer satisfaction and repeat validation. For procurement evaluation, this means the supplier has some transactional proof, but not enough customer feedback or order density to demonstrate strong market performance.

Scoring Rationale:
The supplier should not be treated as commercially unverified because there are recent orders and transaction value. However, 4 orders in six months is modest, and the lack of store rating and customer reviews weakens confidence in sustained business performance. The score reflects low-to-moderate business validation.

Final Score: 10 / 20

4. Service Capability

Basis:
The reported communication response time is ≤4h. No data is provided on Full Customization or other customization capability.

Elaboration:
A response time within four hours indicates acceptable communication responsiveness for initial inquiries and standard procurement communication. However, the dataset does not confirm whether the supplier supports Full Customization, OEM/ODM services, technical customization, private labeling, or engineering support. For industrial equipment procurement, service capability often depends not only on response speed but also on technical communication and customization support, which are not sufficiently evidenced here.

Scoring Rationale:
The supplier meets a basic communication standard but does not reach the highest service tier because response time is not within ≤1 hour and customization capability is not disclosed. The lack of customization data limits confidence in service depth.

Final Score: 6 / 10

5. Delivery Performance

Basis:
The supplier’s on-time delivery rate is 66.7%.

Elaboration:
An on-time delivery rate of 66.7% is below the 70% threshold and represents a clear delivery reliability concern. For buyers sourcing compressors or industrial components, delayed delivery can affect project timelines, equipment installation schedules, and downstream customer commitments. The data does not provide context such as total shipment count, delay reasons, or recent improvement trends, so the evaluation must rely directly on the reported rate.

Scoring Rationale:
According to the scoring standard, delivery performance below 70% should receive less than 5 points. Since 66.7% is meaningfully below the acceptable benchmark, this is one of the supplier’s main risk areas.

Final Score: 4 / 10

6. Quality & Customer Feedback

Basis:
Store rating is not provided, review count is 0, and verified supplier status is marked as True. No Finished Product Inspection information is provided.

Elaboration:
The supplier has some quality credibility through verified supplier status, but there is insufficient customer feedback data to evaluate real buyer satisfaction. The absence of store rating and reviews means there is no visible evidence of product consistency, after-sales experience, or complaint handling from previous buyers. Additionally, Finished Product Inspection is not listed in the provided data, so no conclusion can be made about formal outgoing quality control based on the dataset.

Scoring Rationale:
The score is constrained by missing rating data, 0 reviews, and lack of Finished Product Inspection information. Verified supplier status provides a minimum level of credibility, but it is not enough to establish a strong quality assurance profile. Therefore, the supplier falls into the lower quality-information range rather than a high-confidence quality category.

Final Score: 10 / 20

Procurement Recommendation

Cooperation is conditionally recommended for cautious buyers, especially those seeking air compressor-related products with low MOQ options and who value long platform history and Trade Assurance protection.

Suitable customer types:
- Buyers sourcing portable diesel air compressors, mobile diesel air compressors, compressed air piping, or screw compressor air ends. - Small to medium buyers requiring low MOQ purchasing. - Buyers who can conduct additional supplier qualification before placing larger orders.

Main risk points:
- On-time delivery rate is only 66.7%, creating a clear delivery reliability risk. - Recent order volume is low, with only 4 orders in the past six months. - Store rating is unavailable and review count is 0, limiting customer feedback validation. - Finished Product Inspection data is not provided, so quality control depth is Insufficient Data. - Customization capability is not provided, so suitability for customized projects is Insufficient Data.

Growth potential:
The supplier has a strong platform foundation due to 18 years as a Gold Supplier, Trade Assurance support, verified supplier status, and a reported 12,000+ m2 factory area. If delivery performance improves and more customer feedback becomes available, the supplier could become more attractive for repeat procurement or larger-volume sourcing. For now, buyers should start with sample orders or small trial orders and confirm delivery schedule, inspection process, warranty terms, and technical specifications before scaling cooperation.
