Donghai Mingtian Jewelry Co., Ltd. Supplier Evaluation

Executive Summary

Donghai Mingtian Jewelry Co., Ltd. is a China-based supplier located in Jiangsu, with a reported factory area of 2,100+㎡ and 40+ staff. Based on the available data, the company appears to be a small-to-medium scale supplier with verified supplier status, 7 years as an Gold Supplier, Trade Assurance support, and a 100.0% on-time delivery rate. Its recent platform performance shows 100+ orders and CN¥811.3K+ transaction value over the past six months, supported by a 4.7 store rating and 40+ reviews. The listed product is “Infrequent Natural Purities Native Copper Ore” with a minimum order quantity of 1 kilogram. The supplier is likely suitable for buyers seeking verified platform-backed sourcing with moderate transaction validation and strong delivery reliability. However, data is insufficient regarding customization capability, finished product inspection, specific factory certifications, and broader quality control systems.

Detailed Analysis

1. Company Strength

Basis:
Factory area: 2,100+㎡; staff: 40+; verified supplier: True; location: Jiangsu, China.

Elaboration:
The supplier has a defined physical operating base and a workforce size that indicates basic production and operational capacity. A 2,100+㎡ facility and 40+ staff suggest it is not a large-scale industrial supplier, but it does have measurable infrastructure and human resources to support regular commercial activity.

Scoring Rationale:
The company does not meet the profile of a large-scale stable supply chain due to its moderate factory size and employee count. However, verified supplier status strengthens confidence in its operational legitimacy. The available data supports classification as a small-to-medium supplier with basic production capability.

Final Score: 14 / 20

2. Platform & Compliance Credibility

Basis:
Gold Supplier: True; Gold Supplier duration: 7 years; Trade Assurance: True; certification/industry labels: “Response time ≤4h”, “On-time delivery 100.0%”; verified supplier: True.

Elaboration:
The supplier has a relatively long Gold Supplier history of 7 years, which provides platform continuity. Trade Assurance support adds transaction protection, while verified supplier status improves platform credibility. The available labels show service and delivery-related performance indicators.

Scoring Rationale:
The supplier has strong platform credibility due to Gold Supplier status, 7-year duration, Trade Assurance, and verification. However, the provided certification labels are limited and do not include detailed third-party factory certifications or industry-specific compliance certificates. Therefore, the score is high but not maximum.

Final Score: 18 / 20

3. Business Performance

Basis:
Past 6 months orders: 100+; transaction amount: CN¥811.3K+; store rating: 4.7; reviews: 40+.

Elaboration:
The supplier demonstrates active recent commercial performance, with more than 100 orders and over CN¥811.3K in transaction value during the past six months. The 4.7 rating indicates generally positive buyer satisfaction, while 40+ reviews provide some customer feedback base.

Scoring Rationale:
The order count and transaction value show stable platform activity, but the review volume is moderate rather than extensive. The business data supports a reliable mid-level supplier profile, with meaningful but not top-tier commercial validation.

Final Score: 17 / 20

4. Service Capability

Basis:
Communication response time: ≤4h; Full Customization: Insufficient Data.

Elaboration:
The supplier’s response time of within 4 hours indicates acceptable communication efficiency for normal procurement interaction. However, no data is provided confirming Full Customization, OEM/ODM service, design customization, packaging customization, or other tailored service capabilities.

Scoring Rationale:
The supplier shows reasonable responsiveness, but it does not meet the strongest service capability standard because the response time is not ≤1 hour and customization capability is not confirmed. The service score is therefore placed in the normal-response range.

Final Score: 7 / 10

5. Delivery Performance

Basis:
On-time delivery rate: 100.0%.

Elaboration:
The supplier’s reported on-time delivery rate is 100.0%, which indicates excellent delivery reliability based on the available platform data. This is one of the supplier’s strongest measurable performance indicators.

Scoring Rationale:
According to the scoring standard, an on-time delivery rate above 90% qualifies for 9–10 points. Since the supplier reports 100.0%, it receives the maximum score for this category.

Final Score: 10 / 10

6. Quality & Customer Feedback

Basis:
Store rating: 4.7; reviews: 40+; verified supplier: True; Finished Product Inspection: Insufficient Data; Factory Verification: supplier verification data available, but detailed factory verification scope is Insufficient Data.

Elaboration:
The 4.7 store rating suggests generally positive customer feedback, and 40+ reviews provide a moderate amount of buyer validation. Verified supplier status adds some quality-related credibility, but the provided data does not confirm Finished Product Inspection or detailed quality assurance procedures.

Scoring Rationale:
The supplier has a good rating and some customer review base, but the review volume is not large enough to indicate extensive market validation. Since specific inspection systems and detailed factory verification scope are not provided, the score remains in the good-but-not-complete range.

Final Score: 16 / 20

Total Score

82 / 100

Procurement Recommendation

Cooperation is recommended with controlled order planning. Donghai Mingtian Jewelry Co., Ltd. is suitable for buyers seeking a verified supplier with moderate transaction history, strong delivery performance, Trade Assurance support, and acceptable communication speed. It may be appropriate for small-to-medium procurement needs or trial orders for the listed copper ore product.

Key risks include insufficient data on customization capability, finished product inspection, detailed factory certification, and complete quality control systems. Growth potential exists due to its 7-year Gold Supplier history, 100+ recent orders, CN¥811.3K+ transaction value, and 100.0% on-time delivery rate. For larger or quality-sensitive purchases, buyers should request inspection documents, product specifications, compliance evidence, and sample validation before scaling orders.
