Executive Summary

Foshan Dong Yu Doors And Windows Co., Ltd. is a Guangdong, China-based doors and windows supplier with a reported factory area of 11,000+ square meters and 110+ staff. The supplier appears to have a medium-scale production base supported by verified supplier status, Gold Supplier membership for 5 years, Trade Assurance, and visible platform performance data. Its product listings focus on doors and outdoor/interior entrance solutions, with low minimum order quantities of 2 square meters across the provided items, which may suit buyers requiring flexible project-based purchasing. Business performance is relatively strong, with 90+ orders and CN¥3.7M+ transaction value in the past six months, though the review count is limited at 10+. Service response is stated as within 2 hours, and on-time delivery performance is strong at 93.3%. Overall, this supplier is suitable for buyers seeking a verified mid-sized Chinese doors/windows manufacturer with active platform transactions, while quality confidence is somewhat limited by the small number of customer reviews and insufficient data on formal product inspection systems.

Detailed Analysis

1. Company Strength

Basis
- Factory location: Guangdong, China
- Factory area: 11,000+ ㎡
- Employees: 110+ staff
- Verified supplier: True

Elaboration
The supplier has a clearly stated physical factory scale, with more than 11,000 square meters of operating area and over 110 employees. This indicates a structured manufacturing setup rather than a very small workshop or purely trading-oriented profile. The verified supplier status also strengthens the credibility of the reported company presence and basic operational capability.

Scoring Rationale
The company demonstrates a stable mid-sized factory profile. Its staff count and factory area are sufficient to support regular production, especially for doors and window-related products that typically require space for fabrication, storage, and assembly. However, the provided data does not indicate a very large-scale supply chain, multiple production bases, annual production capacity, or internationally recognized factory management certifications. Therefore, it is stronger than a small basic producer but does not fully qualify as a large-scale supply chain supplier.

Final Score: 16/20

2. Platform & Compliance Credibility

Basis
- Gold Supplier: True
- Gold Supplier duration: 5 years
- Trade Assurance: True
- Verified supplier: True
- Certification/industry labels: “Response time ≤2h”, “On-time delivery 93.3%”
- Formal product or management certifications: Insufficient Data

Elaboration
The supplier has several important platform trust indicators, including Gold Supplier status, 5 years of platform history, Trade Assurance support, and verified supplier status. These factors provide a reasonable level of platform credibility. The available labels relate mainly to response speed and delivery performance, but no independent product certification, quality management certification, or industry-specific compliance certificate is provided in the data.

Scoring Rationale
The supplier has core platform credibility elements in place: a multi-year Gold Supplier history, Trade Assurance, and verification. Five years is a meaningful operating period on the platform and supports buyer confidence. However, the certification label set is not comprehensive, and the data does not show formal factory audit certificates, ISO certification, product compliance documents, or export-market-specific approvals. As a result, the supplier is credible on the platform but not fully documented from a broader compliance standpoint.

Final Score: 16/20

3. Business Performance

Basis
- Orders in past 6 months: 90+
- Transaction value in past 6 months: CN¥3.7M+
- Store rating: 4.7
- Review count: 10+

Elaboration
The supplier shows active recent transaction performance, with more than 90 orders and over CN¥3.7M in transaction value during the past six months. This suggests consistent buyer activity and a measurable commercial track record. The 4.7 store rating is positive, although the review base of 10+ is relatively small compared with the order volume.

Scoring Rationale
The supplier’s commercial performance is above basic validation level because both order volume and transaction amount are clearly present and meaningful. A 4.7 rating supports a generally positive buyer experience. However, the limited number of reviews reduces the statistical strength of the customer feedback, and the data does not provide repeat buyer rate, dispute rate, or detailed transaction distribution. Therefore, the business performance should be considered stable and moderately strong, but not at the highest confidence tier.

Final Score: 16/20

4. Service Capability

Basis
- Communication response time: ≤2h
- Platform label: “Response time ≤2h”
- Full Customization support: Insufficient Data

Elaboration
The supplier’s stated response time is within 2 hours, which indicates relatively efficient communication on the platform. Fast response is valuable for project-based procurement, quotation clarification, drawing confirmation, and order coordination. However, the provided data does not confirm whether the supplier supports Full Customization, design customization, sample customization, or structured engineering support.

Scoring Rationale
The response time is good but does not meet the highest criterion of response within 1 hour. The lack of confirmed Full Customization capability prevents the supplier from being scored as a top-tier service provider. Based on the available evidence, the supplier has acceptable communication efficiency but insufficient proof of advanced customization or technical service capability.

Final Score: 7/10

5. Delivery Performance

Basis
- On-time delivery rate: 93.3%

Elaboration
The supplier’s on-time delivery rate of 93.3% is a strong delivery indicator. For doors and windows, where project schedules and site installation timing can be important, maintaining delivery reliability above 90% is a positive sign. The data does not provide lead time averages, late shipment causes, or order complexity, but the reported percentage itself is favorable.

Scoring Rationale
According to the scoring standard, an on-time delivery rate above 90% qualifies for the 9–10 point range. At 93.3%, the supplier meets the threshold for strong delivery reliability. Since the score is not accompanied by deeper delivery history, shipment volume breakdown, or long-term trend data, it is appropriate to assign a strong but not perfect score.

Final Score: 9/10

6. Quality & Customer Feedback

Basis
- Store rating: 4.7
- Review count: 10+
- Verified supplier: True
- Finished Product Inspection: Insufficient Data
- Factory Verification: Insufficient Data beyond verified supplier status

Elaboration
The store rating of 4.7 suggests generally positive buyer feedback, but the review count of 10+ is limited. The supplier’s verified status provides some credibility regarding company identity or supplier verification, but the data does not confirm specific quality control systems such as Finished Product Inspection, third-party inspection processes, ISO quality certification, or detailed product test reports.

Scoring Rationale
The rating is favorable, but the small review base limits confidence in consistent product quality across different orders or buyer types. Additionally, no Finished Product Inspection system or formal quality certification is provided. The supplier has some quality credibility through platform verification and positive rating, but the quality assurance structure is not sufficiently documented. This places the supplier in the moderate range rather than the high-confidence quality tier.

Final Score: 13/20

Total Score

77/100

Procurement Recommendation

Foshan Dong Yu Doors And Windows Co., Ltd. is recommended for conditional cooperation, especially for buyers seeking a verified mid-sized Chinese supplier for door and window-related products with active platform transactions and strong delivery performance. The supplier is suitable for small to medium project buyers, distributors, contractors, or purchasers who value low MOQ, responsive communication, and Trade Assurance protection.

The main risks are limited customer review volume, insufficient data on Finished Product Inspection, and lack of disclosed formal product or quality management certifications. Before placing larger or technically demanding orders, buyers should request detailed product specifications, quality inspection procedures, production photos or videos, sample confirmation, and any available compliance documents.

The supplier’s growth potential is supported by its 11,000+ ㎡ factory area, 110+ staff, 5-year Gold Supplier history, 90+ recent orders, CN¥3.7M+ transaction value, and 93.3% on-time delivery rate. With stronger documentation of quality control and certification systems, it could become a more reliable option for higher-value or repeat procurement programs.
