Detailed Analysis

1. Company Strength

Basis
- Factory location: Jiangsu, China
- Factory area: 3,700+ m²
- Employees: 100+ staff
- Verified supplier/factory audit status: True

Elaboration
The supplier demonstrates a measurable production foundation with a factory area above 3,700 m² and a workforce exceeding 100 employees. This indicates a structured operating scale rather than a very small trading-only profile. The verified supplier status further supports its basic manufacturing credibility.

Scoring Rationale
The factory size and staff count suggest a medium-scale production capability. While the supplier appears operationally stable, the available data does not indicate a very large-scale industrial setup, extensive production lines, or additional factory certifications beyond verified supplier status. Therefore, it fits the “medium stable factory” range.

Final Score
16 / 20

2. Platform & Compliance Credibility

Basis
- Gold Supplier: True
- Gold Supplier duration: 6 years
- Trade Assurance: True
- Certification/industry tags: Response time ≤2h, On-time delivery 95.5%
- Verified supplier status: True

Elaboration
The supplier has a relatively mature profile, supported by 6 years of Gold Supplier history and Trade Assurance. The verified supplier status provides additional platform credibility. The available tags confirm operational indicators, particularly response speed and delivery reliability.

Scoring Rationale
A 6-year Gold Supplier record, Trade Assurance support, and verified supplier status create a strong credibility base. However, the provided certification/tag information is limited to response and delivery indicators, with no additional product certifications or broader compliance certificates provided. This supports a high but not maximum score.

Final Score
18 / 20

3. Business Performance

Basis
- Orders in past 6 months: 200+
- Transaction value in past 6 months: CN¥1.2M+
- Store rating: 4.7
- Reviews: 40+

Elaboration
The supplier has demonstrated active recent transaction history, with over 200 orders and more than CN¥1.2M in transaction value within six months. The 4.7 rating is positive, while 40+ reviews provide some customer feedback base, though not a very large review volume.

Scoring Rationale
The order count and transaction amount indicate stable commercial activity. The rating is good, supporting buyer satisfaction, but the review count remains moderate rather than extensive. Overall, the supplier shows solid business validation, though not enough evidence for a top-tier commercial performance score.

Final Score
17 / 20

4. Service Capability

Basis
- Communication response time: ≤2h
- Full Customization: Insufficient Data

Elaboration
The supplier’s response time of ≤2 hours indicates reasonably efficient communication. This is suitable for standard sourcing discussions and routine procurement coordination. However, no data is provided confirming Full Customization capability.

Scoring Rationale
The response time is good but does not meet the ≤1 hour benchmark for the highest service score. Since Full Customization capability is not provided, the supplier cannot be rated as having strong customization service based on the available data. A mid-to-good score is appropriate.

Final Score
7 / 10

5. Delivery Performance

Basis
- On-time delivery rate: 95.5%

Elaboration
The supplier’s on-time delivery rate is clearly provided and exceeds 90%, which indicates strong delivery reliability based on the available platform data.

Scoring Rationale
According to the scoring standard, an on-time delivery rate above 90% qualifies for the 9–10 point range. At 95.5%, the supplier demonstrates strong delivery performance and low apparent fulfillment risk based on the provided data.

Final Score
10 / 10

6. Quality & Customer Feedback

Basis
- Store rating: 4.7
- Reviews: 40+
- Verified supplier/factory audit status: True
- Finished Product Inspection: Insufficient Data

Elaboration
The supplier has a positive customer rating of 4.7 and 40+ reviews, which indicates generally favorable buyer feedback. Verified supplier status adds a basic quality credibility layer. However, there is no provided evidence of Finished Product Inspection or a detailed quality control system.

Scoring Rationale
The rating is good and the review base is sufficient for basic feedback validation, but it is not large enough to be considered extensive. The verified supplier status supports credibility, while the absence of Finished Product Inspection data limits the quality assurance assessment. This places the supplier in the good but not top-tier range.

Final Score
15 / 20

Total Score

83 / 100

Procurement Recommendation

Donghai Buildful Jewelry Co., Ltd. is recommended for conditional cooperation, especially for buyers sourcing natural crystal, quartz, gemstone, fluorite, and carved decorative products with flexible low-MOQ requirements. The supplier is suitable for small to medium procurement programs, sample-based purchasing, and buyers who value Trade Assurance and strong delivery reliability.

Main risks include insufficient data on Full Customization capability, Finished Product Inspection, and detailed quality control certifications. Buyers should verify customization scope, inspection procedures, packaging standards, and product consistency before placing larger-volume orders.

Overall, the supplier shows solid platform credibility, stable business performance, and strong delivery metrics. Its growth potential is supported by verified supplier status, 6 years of Gold Supplier history, and active recent transaction volume.
