Weifang Tianyuan Waterproof Material Co., Ltd. Supplier Evaluation
Executive Summary
Weifang Tianyuan Waterproof Material Co., Ltd. is a China-based supplier located in Shandong, with a reported factory area of 17,000+ sqm and 30+ staff. The company appears to be positioned as a manufacturer/supplier of fiberglass-related products, with listed items including insulating glass, fiberglass wire, fireproof fiberglass, and alkali-resistant fiberglass products. Its platform credibility is strong, supported by 9 years as an Gold Supplier, Trade Assurance availability, supplier verification, and customization-related service tags. Commercial performance is also relatively solid, with 50+ orders and CN¥2.5M+ transaction value over the past six months, alongside a 4.9 store rating. The supplier is most suitable for buyers seeking verified Chinese suppliers with medium-scale production capacity, customization support, and stable platform transaction records. Key limitations are the relatively small disclosed workforce and limited review volume, while Finished Product Inspection information is not provided.

Detailed Analysis
1. Company Strength
Basis:
- Factory location: Shandong, China
- Factory area: 17,000+ sqm
- Employees: 30+ staff
- Verified supplier: True
Elaboration:
The supplier has a disclosed factory area of over 17,000 sqm, which indicates a tangible production base rather than a purely trading-oriented profile. The employee count of 30+ suggests a relatively lean workforce, which may be adequate for specialized or semi-automated production, but does not indicate a large-scale labor-intensive manufacturing operation. The verified supplier status adds credibility to the stated company profile and supports the existence of operational capacity.
Scoring Rationale:
The company demonstrates a reasonable physical production base and verified supplier status, which supports basic manufacturing reliability. However, the disclosed workforce size is modest, and there is no additional data on production lines, annual capacity, machinery, or factory audit details. Therefore, the supplier fits best into the category of a medium-sized stable factory rather than a large-scale supply chain operator.
Final Score: 15 / 20
2. Platform & Compliance Credibility
Basis:
- Gold Supplier: True
- Gold Supplier duration: 9 years
- Trade Assurance: True
- Verified supplier: True
- Certification / industry tags: Full customization, ODM service available, Minor customization, Response time ≤2h
Elaboration:
The supplier has maintained Gold Supplier status for 9 years, which indicates a long platform presence. Trade Assurance availability provides buyers with an additional transaction protection mechanism. Verified supplier status further strengthens platform credibility. The listed service and customization tags show that the supplier has completed several platform-recognized profile elements related to buyer service and product customization.
Scoring Rationale:
A 9-year Gold Supplier history, Trade Assurance support, and verified supplier status represent a strong platform credibility profile. The available tags are commercially useful and relatively complete from a buyer-facing perspective. However, the provided data does not include independent third-party product certifications or detailed factory audit documentation beyond supplier verification, so a full perfect score is not assigned.
Final Score: 19 / 20
3. Business Performance
Basis:
- Orders in past 6 months: 50+
- Transaction value in past 6 months: CN¥2.5M+
- Store rating: 4.9
- Review count: 20+
Elaboration:
The supplier has achieved more than 50 orders and over CN¥2.5M in transaction value within the past six months, showing measurable recent commercial activity. A 4.9 store rating indicates positive buyer satisfaction. However, the review count of 20+ is moderate rather than extensive, meaning the public feedback base is still somewhat limited compared with suppliers that have hundreds or thousands of reviews.
Scoring Rationale:
The combination of 50+ orders and CN¥2.5M+ transaction value reflects stable transaction performance and reasonable market validation. The high store rating supports buyer satisfaction, but the relatively limited review count reduces the depth of commercial proof. Overall, the supplier shows solid medium-to-high business performance, but not enough evidence for the highest scoring range.
Final Score: 17 / 20
4. Service Capability
Basis:
- Communication response time: ≤2h
- Platform tags: Full customization, ODM service available, Minor customization
Elaboration:
The supplier provides a response time of within 2 hours, which is acceptable for international sourcing communication and suggests a reasonably responsive sales or service team. The presence of Full customization, Minor customization, and ODM service tags indicates that the supplier can support different levels of buyer customization requirements. However, there is no data on dedicated account management, engineering support, sample lead time, or multilingual service capability.
Scoring Rationale:
The supplier demonstrates good service capability through relatively fast response and multiple customization-related tags. Since the response time is ≤2h rather than ≤1h, and because no further service-process data is provided, the score is placed in the upper part of the normal response and customization-capable range rather than the maximum range.
Final Score: 8 / 10
5. Delivery Performance
Basis:
- On-time delivery rate: 100.0%
Elaboration:
The reported on-time delivery rate is 100.0%, which is a very strong indicator of delivery reliability based on the available platform data. This suggests that recent fulfilled orders were shipped within the expected timeline. However, the data does not specify the number of shipments included in this delivery calculation or the product mix involved.
Scoring Rationale:
According to the scoring framework, an on-time delivery rate above 90% qualifies for 9–10 points. Since the supplier reports a perfect 100.0% on-time delivery rate, it merits the highest score in this category. The score is based strictly on the provided delivery metric.
Final Score: 10 / 10
6. Quality & Customer Feedback
Basis:
- Store rating: 4.9
- Review count: 20+
- Verified supplier: True
- Finished Product Inspection: Insufficient Data
- Factory Verification: Supplier verification is provided as True
Elaboration:
The supplier’s 4.9 store rating indicates strong buyer satisfaction from available feedback. The review count of 20+ provides some customer feedback basis, but it is not large enough to fully confirm long-term quality consistency across a broad buyer base. Supplier verification supports baseline credibility, but the provided data does not confirm Finished Product Inspection or detailed quality control certifications.
Scoring Rationale:
The supplier has a high rating and verified supplier status, both of which support quality confidence. However, the limited review volume and absence of explicit Finished Product Inspection information prevent the supplier from being scored in the highest quality assurance range. The available evidence supports a good but not fully comprehensive quality profile.
Final Score: 16 / 20
Total Score
85 / 100
Score breakdown:
- Company Strength: 15 / 20
- Platform & Compliance Credibility: 19 / 20
- Business Performance: 17 / 20
- Service Capability: 8 / 10
- Delivery Performance: 10 / 10
- Quality & Customer Feedback: 16 / 20
Procurement Recommendation
Cooperation is recommended with controlled qualification steps. The supplier is suitable for buyers seeking a verified China-based supplier with stable platform history, Trade Assurance support, customization capability, and recent transaction performance.
Best-fit customer types include:
- Buyers sourcing fiberglass-related products with standard or customized specifications
- Small to medium importers requiring Trade Assurance-backed transactions
- Buyers that value responsive communication and stable delivery performance
- Procurement teams looking for a medium-scale supplier rather than a very large industrial group
Main risk points:
- Workforce size is relatively modest at 30+ staff
- Review count is limited at 20+, despite a high 4.9 rating
- Finished Product Inspection information is Insufficient Data
- No data is provided on production capacity, machinery, export markets, or third-party product certifications
Growth potential is positive based on 9 years of Gold Supplier history, CN¥2.5M+ recent transaction value, 100.0% on-time delivery, and customization service tags. For larger-volume procurement, buyers should request factory audit documents, quality inspection procedures, sample approval records, and batch-level QC evidence before placing major orders.
