Ningbo Longwell Electric Technology Co., Ltd. Supplier Evaluation

Executive Summary

Ningbo Longwell Electric Technology Co., Ltd. is a China-based supplier located in Zhejiang, with a reported factory area of over 20,000 m² and more than 190 staff. The company appears to have a solid manufacturing base for air-conditioning and fan-related products, including axial fans, cross flow fans, and related air-conditioning components. Its profile shows strong platform credibility, including 9 years as a Gold Supplier, Trade Assurance support, and verified supplier status. Business activity is also visible, with 50+ orders and CN¥3.7M+ transaction value over the past six months, supported by a 5.0 store rating, though the review count is still limited at 10+. Service capability is moderate, with response time within 3 hours, but Full Customization information is not provided. Delivery performance is the main weakness, with an on-time dispatch rate of 72.7%. Overall, this supplier is suitable for buyers seeking an established manufacturing partner with verified platform credentials, but delivery reliability and deeper quality verification should be checked before large-scale procurement.

Detailed Analysis

1. Company Strength

Basis
- Factory location: Zhejiang, China
- Factory area: 20,000+ m²
- Employee count: 190+ staff
- Verified supplier / factory verification status: True
- Product scope includes air-conditioning and fan-related products such as axial fans and cross flow fans

Elaboration
The supplier has a relatively substantial physical manufacturing footprint, with more than 20,000 m² of factory area and over 190 staff. This indicates a production base beyond a small workshop or trading-only operation. The presence of verified supplier status further strengthens the credibility of the stated operational scale. The listed product portfolio is also consistent around air movement and air-conditioning-related components, suggesting a focused manufacturing direction rather than a highly fragmented product mix.

Scoring Rationale
The company fits the profile of a medium-to-large manufacturing supplier. Its factory size and workforce suggest stable production capability, while verified supplier status adds confidence to its operational legitimacy. However, the available data does not include detailed production capacity, equipment lists, annual output, R&D team size, or specific factory audit reports. Therefore, it scores strongly but not at the absolute top level.

Final Score
18 / 20

2. Platform & Compliance Credibility

Basis
- Gold Supplier: True
- Gold Supplier duration: 9 years
- Trade Assurance: True
- Verified supplier: True
- Listed tags: Project solutions, On-site installation, 3D design capabilities, OEM for well-known brands

Elaboration
The supplier demonstrates strong platform credibility. A 9-year Gold Supplier history indicates long-term platform presence, while Trade Assurance provides buyers with an additional transaction protection mechanism. The verified supplier status further supports basic compliance credibility. The listed business capability tags suggest broader service and project support capabilities, although the underlying certification documents or audit details are not provided in the submitted data.

Scoring Rationale
This supplier has a strong platform-backed credibility profile due to its long Gold Supplier history, Trade Assurance support, and verified supplier status. These factors reduce sourcing risk compared with suppliers lacking platform verification. However, the data does not provide specific third-party certifications, ISO certificates, product compliance certificates, or detailed audit documentation. As a result, the score is high but slightly below the maximum.

Final Score
19 / 20

3. Business Performance

Basis
- Orders in the past 6 months: 50+
- Transaction value in the past 6 months: CN¥3.7M+
- Store rating: 5.0
- Review count: 10+

Elaboration
The supplier shows visible commercial traction on the platform. More than 50 orders in six months and over CN¥3.7M in transaction value indicate active buyer engagement and a meaningful transaction record. The 5.0 store rating is positive, but the review count of 10+ is relatively limited, meaning the rating is based on a small visible feedback sample.

Scoring Rationale
The order volume and transaction value support a stable medium-to-strong business performance assessment. The 5.0 score is favorable, but the limited number of reviews reduces the depth of customer validation. The supplier does not yet show enough review volume to fully support a top-tier commercial reliability score, even though transaction value is solid.

Final Score
16 / 20

4. Service Capability

Basis
- Communication response time: ≤3h
- Full Customization: Insufficient Data
- Product listings include OEM/ODM-related wording in one product title
- Platform tags include project solutions, on-site installation, and 3D design capabilities

Elaboration
The response time of within 3 hours indicates acceptable communication efficiency, though it is not at the fastest level of one hour or less. The supplier’s platform tags suggest some project and design support capability, and one product listing references OEM/ODM. However, the submitted data does not explicitly confirm Full Customization support, customization workflow, sample development capability, engineering support details, or dedicated account service.

Scoring Rationale
The supplier appears to have reasonable service capability, especially due to its response time and listed project/design-related tags. However, because response time is not within one hour and Full Customization is not explicitly confirmed, the score should remain in the middle-to-upper range rather than the top tier.

Final Score
7 / 10

5. Delivery Performance

Basis
- On-time dispatch rate: 72.7%

Elaboration
The supplier’s reported on-time dispatch rate is 72.7%, which is a key operational concern. While this does not indicate a complete lack of delivery control, it is below the 80% threshold generally expected for stable procurement execution. For buyers with strict project timelines, seasonal demand, or production-line dependency, this delivery performance may create scheduling risk.

Scoring Rationale
Based on the scoring standard, an on-time dispatch rate between 70% and 79% corresponds to a 5–6 point range. Since 72.7% is closer to the lower-middle part of this range, the supplier receives 5 points. This is the weakest scoring dimension and should be a priority for pre-order clarification.

Final Score
5 / 10

6. Quality & Customer Feedback

Basis
- Store rating: 5.0
- Review count: 10+
- Verified supplier / factory verification: True
- Finished Product Inspection: Insufficient Data
- Product quality certifications: Insufficient Data

Elaboration
The supplier has a perfect visible store rating of 5.0, which is positive, but the review base is limited at 10+. This means customer feedback is favorable but not yet broad enough to represent a large buyer sample. Verified supplier status supports basic quality credibility at the company level, but the data does not confirm Finished Product Inspection, product testing procedures, inspection standards, or formal quality certifications.

Scoring Rationale
The high rating supports a positive quality perception, while verified supplier status gives additional confidence. However, the limited review count and lack of explicit Finished Product Inspection or quality certification data prevent a higher score. The supplier appears acceptable from a quality-feedback perspective, but buyers should request inspection records, QC process details, and product-specific compliance documents before large orders.

Final Score
15 / 20

Total Score

80 / 100

• Quality & Customer Feedback: 15 / 20

Procurement Recommendation

Cooperation is recommended with controlled risk management. Ningbo Longwell Electric Technology Co., Ltd. appears suitable for buyers seeking an established China-based manufacturer of air-conditioning and fan-related products, especially customers who value factory scale, platform credibility, Trade Assurance, and visible transaction history.

The supplier is more suitable for small-to-medium batch buyers, OEM/ODM-oriented buyers requiring air movement components, and importers who can conduct pre-shipment inspection and manage delivery schedules proactively. For urgent projects or strict just-in-time supply chains, caution is advised due to the 72.7% on-time dispatch rate.

Key risks include below-ideal delivery reliability, limited review volume, and insufficient data on Finished Product Inspection, product certifications, and detailed QC systems. Growth potential is supported by its 20,000+ m² factory scale, 190+ staff, 9-year Gold Supplier history, and CN¥3.7M+ transaction value over the past six months. Before placing large orders, buyers should request QC documentation, confirm lead times in writing, use Trade Assurance, and consider third-party inspection.
