Haian Subei Optical Glass Factory Supplier Evaluation
Executive Summary
Haian Subei Optical Glass Factory is a China-based optical glass supplier located in Jiangsu, with a reported factory area of 480+㎡ and 30+ staff. The supplier appears to be a small-scale manufacturer with verified supplier status, long platform history, Trade Assurance support, and product listings focused on customized and OEM optical glass products. Its platform credibility is relatively strong, supported by 17 years as a Gold Supplier and certification/service labels including Finished Product Inspection, ODM service, Minor Customization, and Full Customization. Business activity is moderate, with 30+ orders and CN¥60.8K+ transaction value over the past six months, but the low review count limits commercial validation depth. Service capability is acceptable with response time within 2 hours and customization support. The main concern is delivery reliability, as the on-time dispatch rate is only 75.0%. This supplier may be suitable for buyers seeking low-MOQ customized optical glass components, but procurement should begin with controlled trial orders and strict delivery monitoring.

Detailed Analysis
1. Company Strength
Basis:
- Factory area: 480+㎡
- Employees: 30+ staff
- Verified supplier: True
- Location: Jiangsu, China
Elaboration:
The supplier has identifiable manufacturing information, including factory size, staff count, and verified supplier status. However, the reported factory area and workforce indicate a relatively small production base rather than a large-scale industrial facility. The available data supports basic manufacturing capability, but does not demonstrate high-volume production capacity or extensive factory infrastructure.
Scoring Rationale:
The company has enough evidence to be considered an operating factory with basic production capability, supported by verified supplier status. However, the limited factory area and employee scale place it below medium or large factory benchmarks. There is no additional data showing advanced production lines, capacity volume, or internationally recognized factory certifications.
Final Score: 12 / 20
2. Platform & Compliance Credibility
Basis:
- Gold Supplier: True
- Gold Supplier duration: 17 years
- Trade Assurance: True
- Certification/service labels: Finished Product Inspection, ODM service available, Minor customization, Full customization
Elaboration:
The supplier has a long platform operating history, which is a strong credibility indicator. Seventeen years as a Gold Supplier, combined with Trade Assurance availability, provides meaningful platform-backed transaction confidence. The listed service and inspection labels further strengthen compliance and sourcing transparency.
Scoring Rationale:
This is one of the supplier’s strongest dimensions. Long Gold Supplier tenure, Trade Assurance, and multiple platform labels create a relatively complete credibility profile. The score is not full because no additional third-party certifications, such as ISO or industry-specific certifications, are provided in the data.
Final Score: 19 / 20
3. Business Performance
Basis:
- Past six-month orders: 30+
- Past six-month transaction value: CN¥60.8K+
- Store rating: 4.8
- Reviews: 5
Elaboration:
The supplier has visible transaction activity over the past six months, showing that it is commercially active on the platform. The store rating of 4.8 is positive, but the review count is very limited, which weakens the statistical reliability of customer feedback. Transaction value is present but moderate rather than high.
Scoring Rationale:
The supplier demonstrates stable but not high-volume business performance. Order count and transaction amount indicate real market activity, while the low number of reviews limits validation of consistency across buyers. The supplier fits a moderate-performance profile rather than a high-transaction, highly reviewed supplier.
Final Score: 14 / 20
4. Service Capability
Basis:
- Communication response time: ≤2h
- Full Customization: available
- Minor Customization: available
- ODM service: available
Elaboration:
The supplier shows clear customization capability through Full Customization, Minor Customization, and ODM service labels. Response time within two hours is acceptable for international B2B sourcing, although it does not reach the strongest benchmark of response within one hour.
Scoring Rationale:
The supplier has strong customization indicators, which are important for optical glass procurement. However, because the response time is ≤2h rather than ≤1h, the service capability is assessed as good but not top-tier.
Final Score: 8 / 10
5. Delivery Performance
Basis:
- On-time dispatch rate: 75.0%
Elaboration:
Delivery performance is a notable weakness. A 75.0% on-time dispatch rate means one quarter of orders may not be dispatched on time based on the available platform metric. For buyers with strict project timelines, this creates a measurable supply chain risk.
Scoring Rationale:
According to the scoring standard, an on-time dispatch rate between 70% and 79% corresponds to 5–6 points. Given the rate is in the middle of this band and no additional logistics performance data is available, a conservative score is appropriate.
Final Score: 5 / 10
6. Quality & Customer Feedback
Basis:
- Store rating: 4.8
- Reviews: 5
- Finished Product Inspection: listed
- Verified supplier: True
Elaboration:
The supplier has a strong store rating and a Finished Product Inspection label, which are positive quality-related indicators. Verified supplier status also provides some confidence in operational legitimacy. However, the review count is very low, so the rating cannot be treated as broadly representative.
Scoring Rationale:
Quality assurance indicators are present, especially Finished Product Inspection and verified supplier status. The main limitation is insufficient customer feedback volume. The supplier shows basic quality control credibility, but the limited number of reviews prevents a higher score.
Final Score: 15 / 20
Total Score
73 / 100
Procurement Recommendation
Cooperation is recommended with caution. Haian Subei Optical Glass Factory is suitable for buyers seeking customized optical glass products, OEM/ODM support, and low-MOQ sourcing. Its strongest advantages are long platform history, Trade Assurance support, customization capability, and Finished Product Inspection availability. The main risks are small factory scale, limited review volume, moderate transaction performance, and weak delivery reliability at 75.0% on-time dispatch. Buyers should start with sample orders or small trial batches, confirm specifications clearly, use Trade Assurance, and monitor delivery milestones closely. Growth potential exists if the supplier improves delivery performance and accumulates more verified customer feedback.
