Dongguan Jingnuo Environment Science And Technology Inc. Supplier Evaluation

Executive Summary

Dongguan Jingnuo Environment Science And Technology Inc. is a China-based supplier located in Guangdong, with a reported factory area of 68,000+ m² and 370+ staff. Based on the provided data, the company appears to be a sizeable manufacturer in the air purifier category, offering multiple JNUO air purifier products with both high-MOQ and low-MOQ options. Its profile shows strong platform credibility, including 11 years as a Gold Supplier, Trade Assurance support, verified supplier status, Finished Product Inspection, ODM service availability, Full Customization, and a socially responsible label. Commercial performance is mixed: the supplier recorded CN¥6.7M+ in transaction value over the past six months, but only 7 orders and 3 reviews, which limits the depth of buyer-side validation. The supplier is most suitable for buyers seeking established production capacity, OEM/ODM or customized air purifier sourcing, and medium-to-large procurement projects. Key concerns are the limited number of recent orders and reviews, plus an 88.9% on-time delivery rate that is acceptable but not top-tier.

Detailed Analysis

1. Company Strength

Basis
- Factory area: 68,000+ m²
- Employees: 370+ staff
- Verified supplier: True
- Product scope: multiple air purifier product listings provided

Elaboration
The supplier demonstrates a relatively strong physical manufacturing base, with a large factory area and a workforce of more than 370 staff. These indicators suggest the company has meaningful production infrastructure rather than operating as a small trading entity. The presence of multiple air purifier product listings also supports the view that the supplier has an established product line within the air purification category.

Scoring Rationale
The factory size and employee count indicate a medium-to-large production setup. The verified supplier status further strengthens confidence in its operational presence. However, the provided data does not include detailed annual output, production line quantity, equipment list, capacity utilization, or specific factory audit certificates beyond the verified supplier indication. Therefore, the score is strong but not the absolute maximum.

Final Score
18 / 20

2. Platform & Compliance Credibility

Basis
- Gold Supplier: True
- Gold Supplier duration: 11 years
- Trade Assurance: True
- Verified supplier: True
- Certification / industry labels: Socially responsible, Finished product inspection, ODM service available, Full customization

Elaboration
The supplier has a strong platform credibility profile. An 11-year Gold Supplier history indicates long-term platform presence, while Trade Assurance provides transaction protection for buyers. The verified supplier status and additional labels such as Finished Product Inspection and Socially Responsible add further credibility from a procurement compliance perspective.

Scoring Rationale
This is one of the supplier’s strongest areas. The combination of long Gold Supplier history, Trade Assurance, verified supplier status, and multiple platform-recognized labels forms a relatively complete trust framework. The only limitation is that no specific third-party certifications, compliance certificates, or named audit standards are provided, so the evaluation cannot assume certifications beyond the listed labels.

Final Score
19 / 20

3. Business Performance

Basis
- Orders in past 6 months: 7
- Transaction value in past 6 months: CN¥6.7M+
- Store rating: 5.0
- Number of reviews: 3

Elaboration
The supplier shows a notable transaction value of CN¥6.7M+ over the past six months, which suggests that completed transactions may involve relatively high-value orders. However, the number of orders is low at 7, and the review base is limited to only 3 reviews. This means the commercial record is financially meaningful but not broadly validated by a large number of buyers.

Scoring Rationale
The high transaction value supports a positive business performance score, but the low order count and limited review volume prevent a high-tier rating. A 5.0 store score is favorable, but with only 3 reviews, the reliability of the rating is limited. Overall, the supplier demonstrates confirmed transaction activity, but the breadth of buyer validation remains insufficient for a top score.

Final Score
15 / 20

4. Service Capability

Basis
- Communication response time: ≤5h
- Full Customization: Listed
- ODM service available: Listed

Elaboration
The supplier provides customization-related capabilities, including Full Customization and ODM service availability. This is relevant for buyers requiring branded, modified, or specification-adjusted air purifier products. The response time of ≤5 hours is acceptable for international B2B communication, though it is not within the highest-performance benchmark of one hour or less.

Scoring Rationale
The supplier has clear customization capability, which strengthens its service profile. However, the response time is moderate rather than excellent. Since no additional data is provided on quotation speed, sample development cycle, engineering support, multilingual sales coverage, or after-sales response, the score remains in the solid but not top-tier range.

Final Score
8 / 10

5. Delivery Performance

Basis
- On-time delivery rate: 88.9%

Elaboration
The supplier’s on-time delivery rate falls within the 80%–89% range. This indicates generally acceptable delivery reliability, but it also shows that delays may occur in a meaningful minority of shipments. For buyers with strict retail launch schedules or time-sensitive replenishment needs, this should be monitored carefully.

Scoring Rationale
Based on the provided scoring standard, an 88.9% on-time delivery rate corresponds to the 7–8 point range. Since the figure is close to 90% but still below the higher-performance threshold, the supplier receives the upper end of the 80%–89% band.

Final Score
8 / 10

6. Quality & Customer Feedback

Basis
- Store rating: 5.0
- Number of reviews: 3
- Finished Product Inspection: Listed
- Verified supplier: True
- Factory Verification / detailed factory audit data: Insufficient Data

Elaboration
The supplier has a perfect store rating of 5.0, which is positive, and the presence of Finished Product Inspection suggests some level of product quality control process. Verified supplier status also supports basic confidence in supplier legitimacy. However, the review count is only 3, which is too limited to strongly validate consistent customer satisfaction across multiple buyers or repeated transactions.

Scoring Rationale
The quality framework is supported by Finished Product Inspection and verified supplier status, but the customer feedback base is thin. The 5.0 rating is favorable, yet the small number of reviews reduces statistical reliability. Because detailed quality certificates, inspection reports, defect rates, return rates, and named factory audit results are not provided, the score should remain moderate-to-good rather than high.

Final Score
15 / 20

Total Score

83 / 100

Procurement Recommendation

Recommendation: Recommended for conditional cooperation.

Dongguan Jingnuo Environment Science And Technology Inc. is suitable for buyers seeking air purifier suppliers with established production scale, platform credibility, Trade Assurance protection, ODM capability, and customization support. It is especially appropriate for medium-to-large procurement projects, OEM/ODM sourcing, and buyers who value factory scale and platform-backed transaction security.

The main risks are the low number of recent orders, limited review count, and an on-time delivery rate of 88.9%, which is acceptable but below the top reliability tier. Before placing large-volume orders, buyers should request product specifications, quality inspection documents, lead time confirmation, sample validation, and clear delivery penalty terms.

Overall, the supplier shows strong manufacturing and platform credibility, with growth potential if it can increase buyer feedback volume, improve delivery consistency above 90%, and provide more transparent quality documentation.
