Shenzhen Sanguan Siyuan Technology Co., Ltd. Supplier Evaluation

Executive Summary

Shenzhen Sanguan Siyuan Technology Co., Ltd. is a Guangdong, China-based supplier focused on cable and electronic accessory products, including USB Type C/Micro B cables, Starlink Gen 3 cables, nylon braided charging cables, car cigarette power-related products, and phone charger cables. The company shows a moderate production footprint with a reported factory area of 1,500+㎡ and 40+ staff, supported by verified supplier status. Its platform credibility is relatively strong, with 8 years as a Gold Supplier, Trade Assurance support, response-time labeling, and a 97.2% on-time delivery tag. Business performance is solid, with 200+ orders and CN¥2.8M+ transaction value over the past six months, alongside a 4.9 store rating and 60+ reviews. The supplier appears suitable for buyers seeking stable small-to-medium volume sourcing of cable-related products with verified platform backing and strong delivery performance. However, data is insufficient regarding full customization capability, finished product inspection, and specific factory certification details.

Detailed Analysis

1. Company Strength

Basis
- Factory location: Guangdong, China
- Factory area: 1,500+㎡
- Employees: 40+ staff
- Verified supplier: True

Elaboration
The supplier has a clearly stated factory presence with a moderate physical scale and workforce. A 1,500+㎡ facility and 40+ staff indicate basic in-house production capability rather than a large-scale manufacturing base. The verified supplier status provides some confidence that the company has passed platform-level verification, but there is no detailed data on production lines, monthly capacity, equipment, factory audit scope, or internationally recognized factory certifications.

Scoring Rationale
The company does not reach the level of a large-scale stable supply chain because the factory area and employee count are relatively modest. However, it demonstrates more than minimal capability due to its verified supplier status and established factory information. The available data supports classification as a small-to-medium manufacturer with basic stable production capability.

Final Score
13 / 20

2. Platform & Compliance Credibility

Basis
- Gold Supplier: True
- Gold Supplier duration: 8 years
- Trade Assurance: True
- Certification / industry tags: “Response time ≤2h”, “On-time delivery 97.2%”
- Verified supplier: True

Elaboration
The supplier has a strong platform profile, including 8 years of Gold Supplier history and Trade Assurance support. These factors provide meaningful platform-level credibility for international buyers. The verified supplier status further strengthens trust. However, the available certification labels are mainly operational performance tags rather than detailed compliance certifications, and no specific ISO, product compliance, or factory audit certification is provided.

Scoring Rationale
Eight years as a Gold Supplier plus Trade Assurance and supplier verification represent a mature platform credibility profile. The main limitation is the absence of detailed third-party certification information beyond platform and operational labels. Therefore, the supplier deserves a high score, but not the maximum range for a fully complete certification system.

Final Score
18 / 20

3. Business Performance

Basis
- Orders in the past 6 months: 200+
- Transaction amount in the past 6 months: CN¥2.8M+
- Store rating: 4.9
- Reviews: 60+

Elaboration
The supplier shows clear commercial traction on the platform. More than 200 orders and CN¥2.8M+ transaction value over six months indicate active buyer demand and repeatable transaction execution. A 4.9 store rating is strong, while 60+ reviews provide a moderate customer feedback base. The data supports a commercially validated supplier, although the review count is not large enough to confirm very broad market validation.

Scoring Rationale
The order count, transaction amount, and rating are all positive indicators. The supplier demonstrates stable business activity rather than limited or unproven sales. However, compared with top-tier suppliers with very high order volumes and extensive review bases, the available review quantity remains moderate.

Final Score
17 / 20

4. Service Capability

Basis
- Communication response time: ≤2h
- Full Customization: Insufficient Data

Elaboration
The supplier’s response time is reported as within two hours, which indicates acceptable communication efficiency for sourcing inquiries and order coordination. However, there is no provided evidence that the supplier supports full customization, design customization, OEM/ODM development scope, packaging customization, or engineering support.

Scoring Rationale
The response time is strong but does not meet the highest criterion of ≤1 hour. Since customization capability is not confirmed, the service score should remain in the normal-to-good range rather than the top tier. The supplier appears responsive, but its advanced service depth cannot be fully verified.

Final Score
7 / 10

5. Delivery Performance

Basis
- On-time delivery rate: 97.2%

Elaboration
The supplier’s reported on-time delivery rate of 97.2% is a strong operational indicator. It suggests reliable fulfillment performance and reduced risk of shipping delays for buyers. This is particularly important for cable and accessory products where buyers may require consistent replenishment and predictable lead times.

Scoring Rationale
According to the scoring framework, an on-time delivery rate above 90% qualifies for the 9–10 point range. At 97.2%, the supplier performs well above the threshold and deserves a high score.

Final Score
10 / 10

6. Quality & Customer Feedback

Basis
- Store rating: 4.9
- Reviews: 60+
- Finished Product Inspection: Insufficient Data
- Factory Verification: Verified supplier status provided
- Product-specific quality certifications: Insufficient Data

Elaboration
The supplier has a high store rating of 4.9 and 60+ reviews, indicating generally positive buyer feedback. Verified supplier status adds a basic layer of credibility. However, there is no provided data confirming Finished Product Inspection, formal quality control procedures, product testing standards, defect rates, or product compliance certifications. Therefore, while customer feedback is positive, the quality assurance system cannot be fully evaluated.

Scoring Rationale
The high rating supports a favorable quality perception, but the review base is moderate rather than extensive. The lack of Finished Product Inspection data and detailed quality certification prevents classification as a fully mature quality-controlled supplier. A good but cautious score is appropriate.

Final Score
15 / 20

Total Score

80 / 100

Procurement Recommendation

Cooperation is recommended with standard supplier qualification controls. Shenzhen Sanguan Siyuan Technology Co., Ltd. is suitable for buyers seeking cable-related products from a platform-verified Chinese supplier with strong delivery performance, good transaction history, and responsive communication.

The supplier is best suited for small-to-medium volume importers, e-commerce sellers, distributors, and buyers requiring stable sourcing of USB, charging, Starlink-related, and vehicle power cable products. Key risks include insufficient data on full customization capability, finished product inspection, detailed factory certifications, and product compliance documentation. Its growth potential is supported by 8 years of Gold Supplier status, CN¥2.8M+ recent transaction value, 200+ recent orders, and a 97.2% on-time delivery rate. For larger or compliance-sensitive procurement, buyers should request quality inspection records, certification documents, sample validation, and factory audit details before scaling orders.
