Jiangsu Longdai Environmental Protection Group Co., Ltd. Supplier Evaluation
Executive Summary
Jiangsu Longdai Environmental Protection Group Co., Ltd. is a China-based supplier located in Jiangsu, with a reported factory area of 16,000+ m² and 60+ staff. The company appears to operate as a medium-sized industrial equipment supplier, with listed products including industrial reverse osmosis water systems, liquid dosing systems, water filters, polymer dosing equipment, and water treatment machines. Its platform profile shows 5 years as a Gold Supplier, Trade Assurance support, and supplier/factory verification, which provides a relatively credible platform foundation. Business activity in the past six months includes 10+ orders and CN¥540.9K+ transaction value, supported by a 4.8 store rating but only 6 reviews. The supplier is suitable for buyers seeking water treatment and dosing equipment with low MOQ requirements, especially project-based or small-to-medium procurement needs. Key limitations include limited review volume, moderate order count, and insufficient data on full customization capability.

Detailed Analysis
1. Company Strength — 16 / 20
Basis
- Factory location: Jiangsu, China
- Factory area: 16,000+ m²
- Employees: 60+ staff
- Verified supplier/factory status: True
- Product scope includes reverse osmosis systems, dosing systems, water filters, and water treatment machines.
Elaboration
The reported factory area of over 16,000 m² indicates a meaningful physical production base rather than a very small trading operation. The company’s workforce of 60+ staff suggests a medium-sized operational structure, capable of supporting production, sales, and basic project execution. The listed products are mainly industrial water treatment and dosing-related equipment, which generally require assembly, configuration, testing, and after-sales coordination.
The presence of supplier/factory verification strengthens the credibility of the company’s declared operational base. However, the available data does not provide detailed information on annual production capacity, number of production lines, equipment inventory, engineering team size, export ratio, or major customer references.
Scoring Rationale
This supplier demonstrates stronger-than-basic company strength due to its verified supplier status, sizeable factory area, and moderate employee base. However, the employee count is not large enough to classify it as a large-scale supply chain player, and the absence of detailed production capacity data limits the score. Therefore, it fits the category of a medium-sized stable factory rather than a large-scale manufacturer.
Final Score
16 / 20
2. Platform & Compliance Credibility — 18 / 20
Basis
- Gold Supplier: True
- Gold Supplier duration: 5 years
- Trade Assurance: True
- Verified supplier/factory status: True
- Platform/industry tags: Project solutions, On-site installation, Warranty available, Finished product inspection
Elaboration
The supplier has maintained Gold Supplier status for 5 years, which indicates a relatively established platform presence. Trade Assurance support provides buyers with an additional transaction protection mechanism on the platform. The verified supplier/factory status further improves credibility, as it indicates that certain company or factory information has been checked through the platform verification process.
The listed tags also show relevant commercial and service capabilities, including project solutions, on-site installation, warranty availability, and finished product inspection. These tags are useful for buyers sourcing industrial systems where installation, inspection, and warranty support may be important. However, the data does not include detailed third-party management system certifications such as ISO certificates, nor does it provide full certification documents.
Scoring Rationale
The supplier has a strong platform credibility profile: 5-year Gold Supplier status, Trade Assurance, and verification are all positive indicators. The platform tags are also relevant to industrial project procurement. The score is not full because certification documentation beyond platform tags is not provided, and the available data does not confirm broader compliance systems.
Final Score
18 / 20
3. Business Performance — 14 / 20
Basis
- Past 6-month orders: 10+
- Past 6-month transaction value: CN¥540.9K+
- Store rating: 4.8
- Number of reviews: 6
Elaboration
The supplier has recorded more than 10 orders in the past six months, with a transaction value exceeding CN¥540.9K. This indicates active commercial transactions and some level of buyer validation. The average transaction value appears meaningful relative to the listed product categories, which include industrial water treatment systems and dosing equipment rather than low-value consumer goods.
The store rating of 4.8 is positive and suggests that existing buyers have generally provided favorable feedback. However, the review base is limited, with only 6 reviews, which weakens the statistical reliability of the rating. The order count is also moderate rather than high, so the business performance cannot be categorized as high-volume or strongly proven at scale.
Scoring Rationale
The company shows stable but not outstanding commercial activity. The transaction value is a positive indicator, and the rating is strong, but the order count and review count are relatively limited. This places the supplier in the stable medium-performance range rather than the high-performance category.
Final Score
14 / 20
4. Service Capability — 7 / 10
Basis
- Communication response time: ≤2h
- Full Customization: Insufficient Data
- Service-related tags: Project solutions, On-site installation, Warranty available
Elaboration
The supplier’s reported response time of within 2 hours is acceptable for B2B procurement communication and indicates reasonable responsiveness. For industrial equipment procurement, timely communication is important because buyers often need clarification on technical specifications, installation conditions, configuration requirements, and after-sales service.
The platform tags show that the supplier may support project solutions, on-site installation, and warranty availability. These are relevant service indicators for industrial water treatment projects. However, the data does not explicitly confirm Full Customization capability, engineering customization depth, design support, technical drawing capability, or multilingual service capacity.
Scoring Rationale
The supplier demonstrates a normal-to-good service response level, but not the strongest level defined by the scoring criteria, because the response time is ≤2h rather than ≤1h. In addition, Full Customization is not confirmed in the provided data. The presence of project-related service tags supports a moderate score, but insufficient customization data prevents a higher rating.
Final Score
7 / 10
5. Delivery Performance — 8 / 10
Basis
- On-time dispatch rate: 84.6%
Elaboration
The supplier’s on-time dispatch rate is 84.6%, placing it within the 80%–89% performance range. This suggests that the company has a generally acceptable delivery record but still has room for improvement. For industrial water treatment systems, delivery performance can be affected by configuration complexity, production scheduling, component availability, and project-specific requirements.
The data does not include average lead time, late shipment reasons, logistics methods, or historical delivery consistency across different product categories. Therefore, the score is based strictly on the provided on-time dispatch rate.
Scoring Rationale
According to the required scoring standard, an on-time shipment rate between 80% and 89% corresponds to 7–8 points. At 84.6%, the supplier is in the middle-to-upper part of this range. The performance is acceptable for project-type industrial products, but it does not reach the 90%+ level required for a top delivery score.
Final Score
8 / 10
6. Quality & Customer Feedback — 15 / 20
Basis
- Store rating: 4.8
- Number of reviews: 6
- Finished Product Inspection: Listed as platform/industry tag
- Factory/Supplier Verification: True
Elaboration
The supplier has a high store rating of 4.8, which is a positive customer feedback indicator. The presence of a Finished Product Inspection tag suggests that some level of final inspection process is available before shipment. Factory or supplier verification also supports the reliability of the company’s quality-related claims at a basic platform level.
However, the review count is only 6, which means the rating is based on a small feedback sample. This limits the confidence level of customer satisfaction analysis. The provided data also does not include defect rate, inspection reports, warranty claim records, product testing standards, quality management certifications, or third-party audit results.
Scoring Rationale
The supplier has a good rating and basic quality assurance indicators, including Finished Product Inspection and verification status. These factors support a solid quality score. However, the limited number of reviews and lack of detailed quality system documentation prevent classification as a fully proven high-quality supplier with broad customer validation.
Final Score
15 / 20

| Dimension | Score |
|---|---|
| Company Strength | 16 / 20 |
| Platform & Compliance Credibility | 18 / 20 |
