Changzhou Suma Precision Machinery Co., Ltd. Supplier Evaluation

Executive Summary

Changzhou Suma Precision Machinery Co., Ltd. is a China-based supplier located in Jiangsu, offering precision mechanical components such as sprag clutches, one-way starter clutches, cam followers, and track roller bearings. The supplier shows strong platform credibility, supported by 12 years as an Gold Supplier, Trade Assurance availability, supplier verification, and service/quality-related tags including Finished Product Inspection, Full Customization, ODM service, and Warranty available. Its recent business activity is commercially validated, with 100+ orders and CN¥2.7M+ transaction value over the past six months, supported by a 4.9 store rating and 20+ reviews.

The company appears suitable for buyers seeking low-MOQ precision machinery components with verified platform safeguards and stable delivery performance. However, its physical production scale is relatively limited, with 2,100+ m² factory area and 30+ staff, making it more appropriate for small-to-medium procurement programs rather than very large-volume industrial supply chains without further capacity verification.

Detailed Analysis

1. Company Strength

Basis:
The supplier is located in Jiangsu, China, with a reported factory area of 2,100+ m² and 30+ staff. The data also indicates that it is a verified supplier.

Elaboration:
The factory size and workforce suggest a relatively small manufacturing operation with basic production infrastructure. The presence of supplier verification improves confidence that the company has a legitimate operational base, but the available data does not indicate a large workforce, large-scale plant capacity, automated production lines, annual output, or major factory certifications beyond verification status.

Scoring Rationale:
This supplier does not meet the profile of a large-scale stable supply chain because both factory area and employee count are modest. However, the verified supplier status and active product portfolio indicate that it has basic production capability and operational presence. The company is therefore assessed as a small but functional supplier rather than a weak or unverified manufacturer.

Final Score: 13/20

2. Platform & Compliance Credibility

Basis:
The supplier is listed as an Gold Supplier for 12 years, supports Trade Assurance, and has supplier verification. Certification/industry tags include Warranty available, Finished Product Inspection, Full Customization, and ODM service available.

Elaboration:
A 12-year Gold Supplier history provides strong platform continuity and indicates long-term participation in ’s supplier ecosystem. Trade Assurance improves buyer protection for order execution, while the verification status adds credibility to the supplier profile. The available tags also show a relatively complete platform capability set, covering warranty, inspection, customization, and ODM service.

Scoring Rationale:
The supplier demonstrates a strong combination of long platform history, transaction protection, verification, and relevant capability tags. The only limitation is that no external management system certifications, such as ISO or industry-specific certifications, are provided in the dataset. Based strictly on the available platform data, the supplier has high compliance credibility.

Final Score: 19/20

3. Business Performance

Basis:
Over the past six months, the supplier recorded 100+ orders and CN¥2.7M+ in transaction value. The store rating is 4.9, with 20+ reviews.

Elaboration:
The supplier has clear recent transaction activity, with order volume and sales value showing that buyers are actively purchasing from the company. The transaction value of CN¥2.7M+ is a positive indicator for commercial validation. The store rating of 4.9 is strong, although the review count of 20+ is moderate rather than extensive.

Scoring Rationale:
The supplier shows strong business performance due to meaningful recent transaction value, a solid number of orders, and a high rating. However, the review base is not large enough to classify customer feedback volume as exceptionally deep. This supports a high score, but not the absolute maximum.

Final Score: 18/20

4. Service Capability

Basis:
The supplier’s communication response time is listed as ≤2h. The platform tags include Full Customization and ODM service available.

Elaboration:
A response time within two hours indicates reasonably efficient communication, suitable for normal inquiry handling and order coordination. The Full Customization and ODM service tags suggest that the supplier can support buyer-specific requirements beyond standard catalog sales. However, the data does not confirm response within one hour, dedicated account support, multilingual service capability, sample lead time, or engineering support depth.

Scoring Rationale:
The supplier has good service capability due to acceptable response speed and available customization services. Since the response time is not confirmed as ≤1h, and no additional service process data is provided, the score is strong but below the highest range.

Final Score: 8/10

5. Delivery Performance

Basis:
The supplier’s on-time delivery rate is 96.2%.

Elaboration:
A 96.2% on-time delivery rate is a strong indicator of reliable fulfillment performance. This is especially relevant for mechanical component sourcing, where production planning and delivery consistency are important to downstream assembly, maintenance, or resale operations.

Scoring Rationale:
According to the scoring standard, an on-time delivery rate above 90% qualifies for 9–10 points. At 96.2%, the supplier demonstrates strong delivery reliability based on the provided data.

Final Score: 10/10

6. Quality & Customer Feedback

Basis:
The supplier has a 4.9 store rating and 20+ reviews. The platform tags include Finished Product Inspection, and the supplier is verified.

Elaboration:
The 4.9 rating indicates positive customer satisfaction. Finished Product Inspection is an important quality-control indicator, suggesting that outgoing products may be checked before shipment. Supplier verification also strengthens basic confidence in operational legitimacy. However, the review count is moderate, and the dataset does not provide defect rates, inspection reports, return rates, warranty claim data, or third-party quality certifications.

Scoring Rationale:
The supplier has a strong quality profile based on high rating, available customer reviews, Finished Product Inspection, and verification. The score is not higher because the review base is limited and detailed quality performance metrics are not available.

Final Score: 17/20

Procurement Recommendation

Cooperation is recommended, especially for buyers seeking precision machinery components with low MOQ flexibility, verified platform safeguards, strong delivery reliability, and customization support. The supplier is suitable for small-to-medium procurement programs, sample orders, replacement component sourcing, and customized mechanical component requirements.

Key risks include limited visible production scale, with only 2,100+ m² factory area and 30+ staff disclosed, and a moderate review base of 20+ reviews. There is also Insufficient Data regarding annual production capacity, major factory certifications, detailed quality control documentation, export market coverage, and key customer references.

Overall, Changzhou Suma Precision Machinery Co., Ltd. shows strong platform credibility, good recent commercial performance, and reliable delivery metrics. Its growth potential is supported by long-term presence, Trade Assurance, customization capability, and active transaction data, but larger-volume buyers should request additional capacity and quality documentation before placing major orders.
