Dongying Sunstar Metal Products Co., Ltd. Supplier Evaluation
Executive Summary
Dongying Sunstar Metal Products Co., Ltd. is a China-based supplier located in Shandong, with a reported factory area of 1,000+ m² and 20+ staff. Based on the listed products, the supplier is positioned around marine-related metal products such as deck hatches, portlights, stainless steel boat components, swimming pool/marine hardware, and yacht/ship stainless steel items. The company shows strong platform credibility through 8 years as an Gold Supplier, Trade Assurance support, verified supplier status, and listed service/quality tags including Finished Product Inspection, ODM service, Full Customization, and Warranty available. Commercial activity is moderate, with 40+ orders and CN¥878.9K+ transaction value over the past six months, supported by a 4.9 store rating and 30+ reviews. The supplier appears suitable for buyers seeking small-to-medium batch marine metal products with customization needs, but capacity scale and review volume remain relatively limited compared with larger industrial suppliers.

Detailed Analysis
1. Company Strength
Basis
- Factory location: Shandong, China
- Factory area: 1,000+ m²
- Employees: 20+ staff
- Verified supplier: True
Elaboration
The supplier has a disclosed factory scale and workforce, which provides a basic level of visibility into its production foundation. A 1,000+ m² facility and 20+ employees indicate an operating manufacturing base, but the scale is relatively small compared with large industrial suppliers. The verified supplier status improves confidence that the business has passed some form of supplier verification.
Scoring Rationale
The company demonstrates basic production capability and some operational transparency, but the available data does not indicate a large workforce, large factory footprint, advanced production lines, or extensive production capacity. Therefore, it fits the category of a smaller supplier with basic manufacturing capability rather than a large-scale stable supply chain.
Final Score
12 / 20
2. Platform & Compliance Credibility
Basis
- Gold Supplier: True
- Gold Supplier duration: 8 years
- Trade Assurance: True
- Verification: Verified supplier stated as True
- Tags: Warranty available, Finished Product Inspection, ODM service available, Full customization
Elaboration
The supplier has a relatively strong platform profile. Eight years as a Gold Supplier suggests a longer operating history on the platform, while Trade Assurance gives buyers an additional transaction protection mechanism. The listed tags also show that the supplier presents several compliance and service-related capabilities on the platform.
Scoring Rationale
The combination of long Gold Supplier tenure, Trade Assurance, verified supplier status, and multiple platform tags provides a strong credibility base. The data supports a high score because the core platform trust signals are present and consistent. However, no additional third-party management system certificates or industry-specific certifications are provided, so the score should not reach the absolute maximum.
Final Score
19 / 20
3. Business Performance
Basis
- Orders in past 6 months: 40+
- Transaction value in past 6 months: CN¥878.9K+
- Store rating: 4.9
- Reviews: 30+
Elaboration
The supplier has demonstrated measurable recent commercial activity. More than 40 orders and CN¥878.9K+ in six-month transaction value indicate that the store is active and has completed real transactions. The 4.9 rating is strong, while 30+ reviews provide some customer feedback base, though not a very large sample size.
Scoring Rationale
The transaction value and order count suggest stable but not high-volume business performance. The rating is positive and supports buyer confidence, but the number of reviews remains moderate. This places the supplier in the stable medium-activity category rather than the high-order, high-review category.
Final Score
16 / 20
4. Service Capability
Basis
- Response time: ≤5h
- Full Customization: Listed
- ODM service available: Listed
Elaboration
The supplier shows customization capability through both Full Customization and ODM service tags. A response time of ≤5 hours is acceptable for B2B communication, although it does not meet the strongest benchmark of response within one hour. The available data suggests the supplier can support customized procurement discussions, but communication speed is not at the highest level.
Scoring Rationale
Because the supplier supports Full Customization and ODM service, its service capability is stronger than a basic trading profile. However, the response time is not within the top-tier ≤1h range, so the score should remain within the normal-to-good service band rather than the highest level.
Final Score
8 / 10
5. Delivery Performance
Basis
- On-time delivery rate: 88.9%
Elaboration
The supplier’s on-time delivery rate is close to 90%, indicating generally stable delivery performance. However, it falls slightly below the 90% threshold used for the highest scoring range.
Scoring Rationale
According to the scoring framework, an on-time delivery rate between 80% and 89% corresponds to 7–8 points. At 88.9%, the supplier is near the upper end of this range, so a score of 8 is justified.
Final Score
8 / 10
6. Quality & Customer Feedback
Basis
- Store rating: 4.9
- Reviews: 30+
- Finished Product Inspection: Listed
- Verified supplier: True
- Warranty available: Listed
Elaboration
The supplier has a high store rating and a moderate number of reviews. Finished Product Inspection and Warranty available are positive quality-related indicators. Verified supplier status also supports credibility, although the data does not provide detailed factory audit reports, defect rates, quality certifications, or customer complaint records.
Scoring Rationale
The 4.9 rating indicates good customer satisfaction, and Finished Product Inspection provides a relevant quality-control signal. However, the review base of 30+ is not large, and there is insufficient data on formal quality certifications or detailed inspection procedures. The supplier therefore fits the “good rating with basic quality assurance” category rather than the highest tier.
Final Score
17 / 20
Total Score
79 / 100
Procurement Recommendation
Cooperation is recommended with controlled order planning. Dongying Sunstar Metal Products Co., Ltd. appears suitable for small-to-medium buyers seeking marine-related metal products, especially buyers that require ODM service, Full Customization, Trade Assurance, and moderate MOQ flexibility based on the listed products.
Key risk points include limited disclosed factory scale, relatively small workforce, moderate review volume, and an on-time delivery rate of 88.9%, which is acceptable but below the highest-performance threshold. There is also insufficient data on production equipment, annual capacity, export markets, major customers, formal ISO or industry certifications, and detailed quality inspection procedures.
Growth potential is supported by 8 years of Gold Supplier history, verified supplier status, Trade Assurance availability, CN¥878.9K+ recent transaction value, and strong 4.9 customer rating. For procurement, a reasonable approach would be to start with sample orders or pilot batches, verify product specifications and inspection standards, and use Trade Assurance for initial transactions.
