Dongguan Caiyin Hardware Spring Co., Ltd. Supplier Evaluation

Executive Summary

Dongguan Caiyin Hardware Spring Co., Ltd. is a Guangdong, China-based spring and hardware supplier with a reported factory area of 1,800+ m² and 20+ staff. Its listed product range focuses on steel, stainless steel, extension, trampoline, bending, and constant-force spring products, with relatively low MOQ levels ranging from 100 to 1,000 pieces. The supplier shows solid platform credibility, including 6 years as an Gold Supplier, Trade Assurance support, verified supplier status, Finished Product Inspection, ODM service availability, and Full Customization. Commercial activity is moderate, with 80+ orders and CN¥811.3K+ transaction value over the past six months. However, the company appears to be a small-scale manufacturer rather than a large-capacity factory, and its customer feedback base is limited, with only 6 reviews despite a 4.6 store rating. This supplier is most suitable for buyers seeking customized spring products, low-to-mid volume procurement, and platform-backed transaction protection.

Detailed Analysis

1. Company Strength

Basis
- Factory location: Guangdong, China
- Factory area: 1,800+ m²
- Employees: 20+ staff
- Verified supplier: True

Elaboration
The supplier has a defined factory footprint and workforce, indicating basic in-house production capability. A 1,800+ m² facility with 20+ employees suggests a small-scale manufacturing operation rather than a large industrial supply base. The presence of verified supplier status strengthens confidence that the company has undergone some form of platform-side validation.

Scoring Rationale
The company demonstrates real manufacturing presence and basic operational stability, but the reported factory size and employee count are relatively limited. Based on the available data, it fits the category of a small factory with foundational production capacity rather than a medium or large-scale supplier. The verified supplier status improves the score, but there is insufficient data on production lines, monthly capacity, machinery count, or formal factory management certifications.

Final Score: 12 / 20

2. Platform & Compliance Credibility

Basis
- Gold Supplier: True
- Gold Supplier duration: 6 years
- Trade Assurance: True
- Verified supplier: True
- Certification / industry tags: Warranty available, Finished product inspection, ODM service available, Full customization

Elaboration
The supplier has a strong platform credibility profile. Six years as a Gold Supplier indicates a relatively established platform presence. Trade Assurance provides additional transaction protection, while verified supplier status and inspection-related tags support baseline compliance credibility. The presence of warranty, finished product inspection, ODM service, and full customization labels adds further platform-level reassurance.

Scoring Rationale
This is one of the supplier’s strongest areas. The combination of 6-year Gold Supplier status, Trade Assurance, verified supplier status, and multiple service/quality-related tags forms a relatively complete platform trust profile. While the data does not provide details on third-party certifications such as ISO or specific industry compliance certificates, the platform indicators are strong and mature.

Final Score: 19 / 20

3. Business Performance

Basis
- Orders in past 6 months: 80+
- Transaction value in past 6 months: CN¥811.3K+
- Store rating: 4.6
- Number of reviews: 6

Elaboration
The supplier has recorded visible business activity over the past six months, with more than 80 orders and transaction value exceeding CN¥811.3K. This indicates market traction and active buyer engagement. The 4.6 store rating is positive, but the review base is small, which limits the reliability of the rating as a broad customer satisfaction indicator.

Scoring Rationale
The order volume and transaction amount suggest stable moderate commercial performance rather than very high-volume trading. The store rating is favorable, but only 6 reviews are available, which weakens the validation depth. Overall, the supplier has sufficient transaction evidence to support commercial credibility, but not enough customer feedback volume to justify a top-tier score.

Final Score: 16 / 20

4. Service Capability

Basis
- Communication response time: ≤2h
- Full customization: Available
- ODM service: Available

Elaboration
The supplier shows practical service capability through a response time within two hours and support for both Full Customization and ODM service. These indicators are important for buyers requiring spring specifications, material adjustments, dimensional customization, or product development support.

Scoring Rationale
The response time is good but does not meet the strongest benchmark of ≤1 hour. Full Customization and ODM availability strengthen the supplier’s service profile, especially for custom spring procurement. However, there is insufficient data on engineering support, sample lead time, design assistance, or multilingual sales capability.

Final Score: 8 / 10

5. Delivery Performance

Basis
- On-time delivery rate: 78.3%

Elaboration
The supplier’s on-time delivery rate is below 80%, which indicates delivery performance risk. For buyers with strict replenishment schedules, production timelines, or retail launch deadlines, this metric requires attention before order placement.

Scoring Rationale
According to the scoring framework, a delivery rate between 70% and 79% corresponds to a score of 5 to 6 points. At 78.3%, the supplier is near the upper end of this band but still below the 80% threshold for a more stable delivery rating. This is a notable operational weakness compared with its platform credibility and customization capability.

Final Score: 6 / 10

6. Quality & Customer Feedback

Basis
- Store rating: 4.6
- Number of reviews: 6
- Finished Product Inspection: Available
- Verified supplier: True
- Warranty available: Listed

Elaboration
The supplier has several quality-related platform indicators, including Finished Product Inspection, verified supplier status, and warranty availability. The store rating of 4.6 is positive, suggesting generally favorable customer satisfaction among available reviewers. However, the review count is very limited, making the feedback sample insufficient for strong statistical confidence.

Scoring Rationale
Quality assurance indicators are present, particularly Finished Product Inspection and verified supplier status. These support a reasonable quality control baseline. However, only 6 reviews are available, which prevents the supplier from being rated as having a broad and highly validated customer feedback record. The score reflects good quality signals but limited review depth.

Final Score: 15 / 20

Total Score

76 / 100

• Company Strength: 12 / 20
• Platform & Compliance Credibility: 19 / 20
• Business Performance: 16 / 20
• Service Capability: 8 / 10
• Delivery Performance: 6 / 10
• Quality & Customer Feedback: 15 / 20

Procurement Recommendation

Dongguan Caiyin Hardware Spring Co., Ltd. is recommended for conditional cooperation, especially for buyers sourcing customized spring products in low-to-medium order volumes. The supplier is suitable for customers who value platform protection, Trade Assurance, ODM support, Full Customization, and Finished Product Inspection.

The main strengths are its strong platform credibility, 6-year Gold Supplier status, verified supplier profile, active six-month transaction record, and customization capability. The main risks are its small factory scale, limited staff size, low review count, and on-time delivery rate of 78.3%, which may create schedule uncertainty for time-sensitive orders.

For procurement use, this supplier is better suited for sample orders, customized development projects, and repeat orders after performance validation. For large-volume or strict-delivery programs, buyers should verify production capacity, lead time, inspection process, and delivery commitments before placing bulk orders. Its growth potential is supported by active transaction performance and service flexibility, but delivery reliability and broader customer feedback remain areas requiring further validation.
