Nantong Zhonglong Hydraulic Co., Ltd. Supplier Evaluation

Executive Summary

Nantong Zhonglong Hydraulic Co., Ltd. is a China-based supplier located in Jiangsu, with a reported factory area of 5,300+ m² and 190+ staff. The company appears to have a moderate manufacturing base and is marked as a verified supplier, which provides some level of production and platform credibility. Its listed products include soda maker-related components, pressure transmitters, air compressor line filters, and filter elements, suggesting a supply focus around industrial filtration, hydraulic, pneumatic, or related component categories based strictly on the provided listings.

From a procurement perspective, the supplier may be suitable for buyers seeking low-MOQ sourcing, sample orders, or early-stage supplier qualification. However, its commercial validation is currently weak: only 1 order and CN¥678.8+ transaction value in the past six months, with just 1 review. The 50.0% on-time delivery rate is a significant operational risk. This supplier should be approached cautiously, preferably through small trial orders and Trade Assurance.

Detailed Analysis

1. Company Strength

Basis
- Factory location: Jiangsu, China
- Factory area: 5,300+ m²
- Employees: 190+ staff
- Verified supplier: True

Elaboration
The supplier has a documented factory area above 5,000 m² and a workforce of more than 190 staff, which indicates a meaningful physical production base rather than a very small trading setup. The presence of a verified supplier status further supports the existence of some supplier verification or factory-related validation. However, the provided data does not include detailed production capacity, production lines, annual output, machinery list, or factory audit reports.

Scoring Rationale
The company demonstrates characteristics of a medium-sized and relatively stable factory, supported by factory size, staffing level, and verified supplier status. However, it does not reach the highest scoring range because the data lacks detailed evidence of large-scale production capacity, formal factory certifications, or audit documentation beyond the verified supplier indicator.

Final Score
16 / 20

2. Platform & Compliance Credibility

Basis
- Gold Supplier: True
- Gold Supplier duration: 2 years
- Trade Assurance: True
- Certification / industry tags: “Response time ≤7h”, “On-time delivery 50.0%”
- Verified supplier: True

Elaboration
The supplier has several core platform credibility indicators, including Gold Supplier status, Trade Assurance support, and verified supplier status. These are positive signals for platform-level transaction protection and basic credibility. However, the Gold Supplier history is only 2 years, which is relatively short compared with long-established suppliers. The certification or industry tag information is also limited and does not show broader compliance certifications, product certifications, or management system certifications.

Scoring Rationale
The supplier has the essential platform credibility elements needed for initial sourcing consideration, especially Trade Assurance and verified supplier status. The score is limited by the short Gold Supplier duration and incomplete certification label coverage. The available tags are operational indicators rather than strong compliance certifications.

Final Score
15 / 20

3. Business Performance

Basis
- Orders in the past 6 months: 1
- Transaction amount in the past 6 months: CN¥678.8+
- Store rating: 5.0
- Number of reviews: 1

Elaboration
The supplier has a perfect store rating of 5.0, but this rating is based on only 1 review, making the statistical reliability very limited. The past six-month order count and transaction amount are both low, showing limited recent commercial activity on the platform. While the existing transaction result is positive in rating terms, the supplier has not yet demonstrated strong order volume, repeat purchasing evidence, or significant platform transaction scale.

Scoring Rationale
The business performance score is constrained primarily by the very low number of orders and small transaction value. A 5.0 rating is favorable, but with only 1 review, it cannot be treated as strong market validation. The supplier shows initial commercial activity but insufficient evidence of stable or high-volume platform performance.

Final Score
10 / 20

4. Service Capability

Basis
- Communication response time: ≤7h
- Full Customization: Insufficient Data

Elaboration
The supplier’s response time of within 7 hours indicates acceptable but not high-speed communication performance. There is no provided evidence that the supplier supports Full Customization, engineering customization, private labeling, OEM/ODM services, or dedicated project communication processes. Therefore, the service assessment must be limited to the available response-time indicator.

Scoring Rationale
The response time is functional for ordinary sourcing communication, but it does not meet the strongest benchmark of response within 1 hour. Since customization capability is not provided, the supplier cannot be scored as having strong service capability. The score reflects basic responsiveness with insufficient evidence of advanced service support.

Final Score
6 / 10

5. Delivery Performance

Basis
- On-time delivery rate: 50.0%

Elaboration
The reported on-time delivery rate of 50.0% is significantly below the preferred procurement benchmark. This indicates that only half of the measured deliveries were completed on time, based on the provided data. No additional information is available regarding sample shipment speed, average lead time, logistics process, production scheduling, or causes of delay.

Scoring Rationale
According to the scoring framework, delivery performance below 70% should receive fewer than 5 points. A 50.0% on-time delivery rate represents a clear operational risk, particularly for buyers with strict replenishment schedules, project deadlines, or production-line dependency.

Final Score
3 / 10

6. Quality & Customer Feedback

Basis
- Store rating: 5.0
- Number of reviews: 1
- Verified supplier: True
- Finished Product Inspection: Insufficient Data
- Factory Verification: True / supplier verification indicated

Elaboration
The supplier has a 5.0 store rating, but this is supported by only 1 review, which is not enough to establish a reliable quality track record. Verified supplier status provides some confidence that the supplier has passed a platform-level verification process. However, the data does not confirm Finished Product Inspection, quality control procedures, product testing standards, defect rates, return rates, or third-party quality certifications.

Scoring Rationale
The supplier has positive but very limited customer feedback. The verified supplier status is useful, but the lack of confirmed finished product inspection and the extremely small review base reduce confidence in consistent quality performance. The score reflects acceptable initial quality signals but insufficient evidence for a stronger rating.

Final Score
12 / 20

Total Score

Company Strength: 16 / 20
Platform & Compliance Credibility: 15 / 20
Business Performance: 10 / 20
Service Capability: 6 / 10
Delivery Performance: 3 / 10
Quality & Customer Feedback: 12 / 20

Total Score: 62 / 100

Procurement Recommendation

Nantong Zhonglong Hydraulic Co., Ltd. can be considered for cautious, small-scale cooperation, especially for buyers seeking low-MOQ orders, sample testing, or preliminary supplier development. The supplier has a moderate factory base, verified supplier status, Gold Supplier status, and Trade Assurance support, which make it more credible than suppliers with no platform backing.

However, it is not currently recommended for urgent, high-volume, or delivery-critical procurement due to the 50.0% on-time delivery rate and very limited recent transaction history. The main risks are weak commercial validation, low review count, insufficient quality inspection data, and poor delivery performance.

The supplier’s growth potential lies in its physical factory scale and staffing base. If future data shows improved delivery reliability, more transaction volume, stronger customer feedback, and confirmed inspection processes, it could become a more suitable long-term sourcing option. For now, buyers should use Trade Assurance, start with trial orders, confirm lead times in writing, and request inspection evidence before scaling purchases.
