Shandong Wolize Biotechnology Co., Ltd. Supplier Evaluation

Executive Summary

Shandong Wolize Biotechnology Co., Ltd. is a China-based supplier located in Shandong, offering flexible liquid storage products such as water storage bladder tanks, foldable inflatable drinking water tanks, PVC fuel bladders, and large-capacity reusable plastic water storage solutions. The supplier shows credible platform backing, including 7 years as an Gold Supplier, Trade Assurance support, verified supplier status, and platform labels such as Finished Product Inspection, ODM service, Full Customization, and Warranty available. Its factory scale is relatively small to moderate, with 2,000+ m² factory area and 20+ staff, but the verified supplier status provides a baseline level of operational credibility. Business performance is solid, with 20+ orders and CN¥3.6M+ transaction value over the past six months, supported by a 4.9 store rating and 20+ reviews. This supplier appears suitable for buyers seeking flexible tank products with customization needs, low MOQ, and platform-backed transaction protection, while larger enterprise buyers should further verify production capacity before large-volume procurement.

Detailed Analysis

1. Company Strength

Basis
Factory area: 2,000+ m²; employees: 20+ staff; verified supplier: True.

Elaboration
The supplier has a physical production base with a stated factory area above 2,000 m² and a workforce of more than 20 staff. This indicates basic manufacturing capability rather than a large-scale industrial operation. The verified supplier status adds credibility, but the available data does not include detailed production lines, monthly output, machinery count, factory audit reports, or internationally recognized factory certifications.

Scoring Rationale
The company demonstrates legitimate factory presence and basic production capacity, but its scale is closer to a small or lower-mid-sized manufacturing operation. The verified supplier status supports operational credibility, yet the absence of detailed production capacity data limits confidence for high-volume sourcing.

Final Score
12 / 20

2. Platform & Compliance Credibility

Basis
Gold Supplier: True; Gold Supplier tenure: 7 years; Trade Assurance: True; certification/industry labels: Warranty available, Finished Product Inspection, ODM service available, Full customization.

Elaboration
The supplier has a relatively mature platform history with 7 years as a Gold Supplier. Trade Assurance provides transaction protection, while the listed platform labels indicate service and compliance-related capabilities. The presence of Finished Product Inspection and Warranty available strengthens buyer confidence. However, no independent third-party certifications, product compliance certificates, or international standards are provided in the data.

Scoring Rationale
The supplier has strong platform credibility due to its 7-year Gold Supplier status, Trade Assurance support, verified supplier profile, and multiple relevant capability labels. The score is high, but not full, because external compliance documentation is not provided.

Final Score
18 / 20

3. Business Performance

Basis
Past 6-month orders: 20+; past 6-month transaction value: CN¥3.6M+; store rating: 4.9; reviews: 20+.

Elaboration
The supplier has recorded visible transaction activity over the past six months, with more than 20 orders and transaction value exceeding CN¥3.6M. This suggests meaningful commercial traction rather than purely inactive platform presence. The 4.9 rating is strong, while 20+ reviews provide some customer feedback, though the review base is still not large enough to represent broad market validation.

Scoring Rationale
The transaction value is solid and the rating is high, but order count and review volume are moderate rather than extensive. The supplier appears commercially active and credible, but not yet at the level of a high-volume, heavily reviewed platform leader.

Final Score
16 / 20

4. Service Capability

Basis
Response time: ≤2h; Full Customization: listed; ODM service available: listed.

Elaboration
The supplier demonstrates acceptable communication responsiveness with a response time of no more than two hours. The availability of Full Customization and ODM service indicates that the supplier can support customized requirements, which is relevant for bladder tanks and flexible storage products where size, capacity, and usage conditions may vary. No additional data is provided on engineering support, sample lead time, design documentation, or multilingual sales support.

Scoring Rationale
The supplier shows good service capability because response speed is relatively quick and customization support is clearly listed. However, the response time does not meet the strongest benchmark of ≤1 hour, and deeper service-process information is insufficient.

Final Score
8 / 10

5. Delivery Performance

Basis
On-time delivery rate: 95.0%.

Elaboration
A 95.0% on-time delivery rate indicates strong delivery reliability based on the available platform data. This is a positive indicator for buyers who require predictable shipment performance. However, the data does not include lead times, production cycle length, logistics methods, shipment destinations, or historical delay causes.

Scoring Rationale
The on-time delivery rate exceeds 90%, which supports a high delivery score. While supporting logistics details are insufficient, the available metric itself is strong and directly relevant to procurement reliability.

Final Score
10 / 10

6. Quality & Customer Feedback

Basis
Store rating: 4.9; reviews: 20+; Finished Product Inspection: listed; verified supplier: True.

Elaboration
The supplier has a high store rating of 4.9 and more than 20 reviews, indicating generally positive customer feedback. The Finished Product Inspection label suggests that some level of final-stage quality checking is available. Verified supplier status further supports baseline credibility. However, the data does not include defect rates, inspection standards, test reports, warranty claim history, product certifications, or detailed customer complaint records.

Scoring Rationale
Quality indicators are positive, especially the high rating and Finished Product Inspection label. The score is not higher because the review count remains moderate and there is insufficient data on formal quality systems or product compliance certifications.

Final Score
16 / 20

Total Score

80 / 100

Procurement Recommendation

Cooperation is recommended with controlled order validation. Shandong Wolize Biotechnology Co., Ltd. is suitable for buyers seeking flexible water or fuel bladder tanks, customized sizes, low MOQ procurement, and Trade Assurance protection. It is especially appropriate for small to medium-volume buyers or project-based procurement requiring customization.

Main risks include limited visible factory scale, only moderate review volume, and insufficient data on production capacity, product certifications, testing standards, and detailed quality control procedures. Before large-volume or high-risk procurement, buyers should request factory audit documents, product test reports, material specifications, sample approval, and pre-shipment inspection.

The supplier shows growth potential due to strong platform credibility, solid recent transaction value, high store rating, customization capability, and strong on-time delivery performance.
