Shenzhen Everwin Tech Co., Limited Supplier Evaluation

Executive Summary

Shenzhen Everwin Tech Co., Limited is a China-based supplier located in Guangdong, offering multiple lithium battery-related products, including Li polymer batteries, solid state batteries, ternary lithium batteries, and LiFePO4 cylindrical cells. The supplier shows strong platform credibility, supported by 17 years as an Gold Supplier, Trade Assurance availability, and verified supplier status. Its recent business performance indicates measurable commercial activity, with 30+ orders and CN¥743.7K+ transaction value over the past six months. However, key factory capacity indicators such as factory area and employee count are not provided, limiting assessment of production scale. Service response is within 3 hours, but Full Customization capability is not stated. Delivery performance is a major concern, with an on-time delivery rate of only 66.7%. Overall, this supplier may be suitable for buyers seeking battery products from a long-established platform supplier, but cooperation should be conditional on delivery risk control, sample validation, and clearer production capability disclosure.

Detailed Analysis

1. Company Strength

Basis:
- Country/Region: China, Guangdong
- Factory area: Insufficient Data
- Employee count: Insufficient Data
- Verified supplier: True
- Product scope includes several lithium battery-related items

Elaboration:
The supplier presents itself as a battery-related product provider with listings across Li polymer batteries, solid state batteries, ternary lithium batteries, and LiFePO4 cylindrical cells. This indicates a product portfolio focused on rechargeable battery applications. However, the absence of factory area and employee count prevents a clear judgment of manufacturing scale, workforce depth, or production capacity. The verified supplier status provides some factory or supplier credibility, but it does not fully replace direct capacity indicators.

Scoring Rationale:
The company has basic supplier credibility through verified supplier status and an observable product range. However, because factory area and employee size are missing, it cannot be classified as a medium or large-scale stable factory based on the available data. The score reflects basic production capability with significant information gaps.

Final Score: 11 / 20

2. Platform & Compliance Credibility

Basis:
- Gold Supplier: True
- Gold Supplier duration: 17 years
- Trade Assurance: True
- Verified supplier: True
- Certification/industry labels: “Response time ≤3h”, “On-time delivery 66.7%”

Elaboration:
The supplier has a long platform history, with 17 years as a Gold Supplier, which is a strong indicator of platform continuity. Trade Assurance support adds transaction protection, and verified supplier status improves baseline credibility. However, the provided certification or industry labels mainly relate to response time and delivery performance rather than product certifications, factory certifications, or compliance standards.

Scoring Rationale:
The supplier performs strongly in platform credibility due to long Gold Supplier tenure, Trade Assurance, and verification status. The score is not full because the available certification labels are incomplete from a compliance perspective, and no specific factory certification, product certification, or industry compliance certificate is provided.

Final Score: 18 / 20

3. Business Performance

Basis:
- Past 6-month orders: 30+
- Past 6-month transaction value: CN¥743.7K+
- Store rating: 4.5
- Reviews: 10+

Elaboration:
The supplier has demonstrated recent transaction activity, with more than 30 orders and more than CN¥743.7K in transaction value over the past six months. This suggests that the supplier has active commercial engagement rather than being an inactive storefront. The 4.5 store rating is positive, though the review base of 10+ remains relatively limited for broader customer validation.

Scoring Rationale:
The transaction value is meaningful, and the supplier has a visible order record. However, the order volume and review count do not indicate a high-volume supplier with extensive market validation. The score reflects stable medium-level business performance rather than top-tier commercial traction.

Final Score: 15 / 20

4. Service Capability

Basis:
- Communication response time: ≤3h
- Full Customization: Insufficient Data

Elaboration:
A response time of within 3 hours indicates acceptable communication efficiency for sourcing discussions and quotation follow-up. However, there is no provided evidence that the supplier supports Full Customization, engineering customization, private labeling, or buyer-specific product development.

Scoring Rationale:
The supplier demonstrates reasonable responsiveness, but the lack of customization information limits the service capability assessment. Since strong customization capability is not confirmed and response time is not within one hour, the supplier is rated as having normal service capability rather than advanced buyer support.

Final Score: 6 / 10

5. Delivery Performance

Basis:
- On-time delivery rate: 66.7%

Elaboration:
The supplier’s on-time delivery rate is 66.7%, which is below the 70% threshold. This indicates a material delivery reliability concern, especially for buyers with strict production schedules, seasonal sales windows, or project-based procurement deadlines.

Scoring Rationale:
Based on the stated scoring rule, an on-time delivery rate below 70% should receive below 5 points. The score reflects a clear logistics and fulfillment risk that should be addressed before placing larger or time-sensitive orders.

Final Score: 4 / 10

6. Quality & Customer Feedback

Basis:
- Store rating: 4.5
- Reviews: 10+
- Finished Product Inspection: Insufficient Data
- Factory Verification / Verified supplier: True

Elaboration:
The supplier’s 4.5 rating suggests generally positive buyer feedback, but the review count of 10+ is not large enough to establish broad customer confidence. Verified supplier status provides some quality-related reassurance at the supplier level. However, there is no provided evidence of Finished Product Inspection, specific battery certifications, or documented quality management systems.

Scoring Rationale:
The supplier has a favorable rating and some verification support, but customer feedback volume is limited and formal quality assurance data is incomplete. The score reflects moderate quality confidence with important gaps in inspection and certification evidence.

Final Score: 12 / 20

Total Score

66 / 100

Procurement Recommendation

Cooperation is conditionally recommended for buyers seeking lithium battery-related products from a long-established supplier with Trade Assurance support. The supplier may be suitable for small to medium-volume buyers, sample-based sourcing, and buyers who can tolerate delivery uncertainty during initial cooperation.

Key risks include Insufficient Data on factory area and employee count, unclear customization capability, limited review volume, missing Finished Product Inspection information, and a weak on-time delivery rate of 66.7%. Before scaling orders, buyers should request factory capacity details, inspection procedures, product compliance documents, sample testing, and written delivery commitments. The supplier’s growth potential lies in its long platform history, active transaction record, and verified supplier status, but delivery reliability and quality documentation need improvement.
