Detailed Analysis

1. Company Strength

Basis
- Factory location: Guangdong, China
- Factory area: 530+ sqm
- Employees: 20+ staff
- Verified supplier: True
- Product scope includes multiple glass film and PDLC smart film items

Elaboration
The supplier has a physical factory presence with a stated area of 530+ sqm and more than 20 staff. This indicates basic manufacturing or processing capability, but the scale remains relatively small compared with larger industrial suppliers. The verified supplier status improves confidence that the company has undergone some form of platform or supplier verification. The listed product range is focused on glass film, smart tint film, and PDLC privacy film, suggesting a specialized product direction rather than a broad unrelated catalog.

Scoring Rationale
The company has verifiable operating fundamentals, including factory space, staff count, and supplier verification. However, the factory area and workforce size point to a small-scale operation rather than a large manufacturing base. There is no provided evidence of large-scale production lines, annual capacity, advanced manufacturing equipment, or internationally recognized factory certifications. Therefore, the supplier fits the category of a small factory with basic production capability and some verification support.

Final Score
12 / 20

2. Platform & Compliance Credibility

Basis
- Gold Supplier: True
- Gold Supplier duration: 4 years
- Trade Assurance: True
- Verified supplier: True
- Platform tags: Response time ≤1h; On-time delivery 98.8%
- Other certification or industry labels: Insufficient Data

Elaboration
The supplier has several important platform credibility indicators. A 4-year Gold Supplier history shows a continued platform presence, while Trade Assurance provides an additional transaction protection mechanism for buyers. Verified supplier status further supports basic credibility. The platform tags related to response time and on-time delivery strengthen operational transparency, although the data does not include detailed factory audit reports, product certifications, or third-party compliance certificates.

Scoring Rationale
The supplier demonstrates a solid platform compliance foundation through Gold Supplier status, Trade Assurance, and verification. Four years of Gold Supplier history is meaningful but not long enough to qualify as a highly mature long-term platform record. Certification-label completeness is limited because no detailed compliance certificates, industry certifications, or audit documentation are provided. As a result, the supplier has credible platform backing but not a fully comprehensive certification profile.

Final Score
16 / 20

3. Business Performance

Basis
- Orders in the past 6 months: 100+
- Transaction value in the past 6 months: CN¥743.7K+
- Store rating: 4.6
- Reviews: 20+

Elaboration
The supplier has recorded more than 100 orders in the past six months, showing active commercial performance on the platform. The transaction value of CN¥743.7K+ indicates a moderate level of recent sales activity. A 4.6 store rating is generally positive, though not exceptionally high, and the review count of 20+ provides some customer feedback but remains limited in volume. Overall, the data supports the conclusion that this supplier has real marketplace traction, but not yet at a high-volume or highly validated level.

Scoring Rationale
The supplier’s recent order count is healthy for a smaller manufacturer, and the transaction value shows measurable commercial activity. However, the review base is relatively small, and the store rating, while good, does not reach the strongest level of customer validation. The business record is stronger than a low-activity supplier but does not fully support a top-tier score due to limited review depth and only moderate transaction evidence.

Final Score
15 / 20

4. Service Capability

Basis
- Communication response time: ≤1h
- Platform tag: Response time ≤1h
- Full Customization: Insufficient Data

Elaboration
The supplier demonstrates strong responsiveness, with a stated communication response time of within one hour. This is a positive indicator for inquiry handling, quotation follow-up, and pre-order communication. However, the provided data does not state whether the supplier supports Full Customization, ODM, OEM, design customization, or technical customization. For glass film and PDLC-related products, customization capability can be important, but it cannot be assumed without explicit data.

Scoring Rationale
The response time meets the strongest service-response benchmark. However, service capability scoring also considers customization support, and the dataset does not confirm Full Customization or equivalent capability. Therefore, the supplier deserves a good but not maximum service score: communication efficiency is strong, while customization depth remains unverified.

Final Score
8 / 10

5. Delivery Performance

Basis
- On-time delivery rate: 98.8%

Elaboration
The supplier’s stated on-time delivery rate of 98.8% is a strong delivery-performance indicator. This suggests that the supplier has been able to fulfill orders within the expected delivery timeline at a high reliability level. For procurement teams, this reduces the risk of schedule disruption, especially for repeat orders or project-based sourcing where delivery timing is important.

Scoring Rationale
According to the scoring standard, an on-time delivery rate above 90% qualifies for 9 to 10 points. At 98.8%, the supplier performs near the upper end of the benchmark. The score is not set at the absolute maximum only because the data does not include shipment volume breakdown, destination markets, logistics method, or delay-dispute history.

Final Score
9 / 10

6. Quality & Customer Feedback

Basis
- Store rating: 4.6
- Reviews: 20+
- Verified supplier: True
- Finished Product Inspection: Insufficient Data
- Factory Verification: Verified supplier status provided, but detailed factory verification scope is Insufficient Data

Elaboration
The supplier has a positive store rating of 4.6 and more than 20 reviews, indicating that some buyers have provided favorable feedback. Verified supplier status adds a basic level of credibility. However, the review count is not large, and the provided data does not confirm Finished Product Inspection, detailed quality control procedures, product testing standards, or specific factory verification scope. For smart film and PDLC film products, quality consistency can be important, but the available data is not sufficient to evaluate deeper quality assurance systems.

Scoring Rationale
The supplier has acceptable customer feedback and some verification support, but the quality evidence is not comprehensive. The 4.6 rating is positive, though the limited review count reduces statistical confidence. The absence of confirmed Finished Product Inspection or detailed quality-control certification prevents a higher score. Therefore, the supplier is assessed as having basic-to-good quality indicators, with further due diligence required before large-volume procurement.

Final Score
14 / 20

Total Score

74 / 100

Procurement Recommendation

Shenzhen Coast Glass Co., Ltd. is recommended for conditional cooperation, especially for buyers seeking small-to-medium volume sourcing, sample orders, trial procurement, or flexible purchasing of glass film and PDLC smart film products. The supplier shows solid platform credibility, fast response capability, active recent transaction performance, and strong delivery reliability.

The main risks are limited production scale, relatively small review volume, and insufficient data on Finished Product Inspection, factory audit scope, product certifications, and customization capability. These gaps are especially relevant for buyers requiring strict technical compliance, consistent optical/electrical performance, or high-volume project delivery.

The supplier’s growth potential is moderate to positive. Its 100+ recent orders, CN¥743.7K+ six-month transaction value, 4-year Gold Supplier history, and 98.8% on-time delivery rate indicate operational momentum. Before placing large or long-term orders, buyers should request quality inspection documentation, sample validation, production capacity details, and clarification on customization support.
