Based on the provided data, the company operates a factory of over 2,900㎡ with more than 50 staff and is marked as a verified supplier, indicating basic-to-mid scale manufacturing capability rather than a large-scale industrial operation. Its platform credibility is comparatively strong, supported by 8 years as a Gold Supplier, Trade Assurance, Finished Product Inspection, Full Customization, and warranty-related platform tags. Commercial performance appears moderate, with 80+ orders and CN¥67.6K+ transaction value over the past six months, supported by a 4.4 store rating and 30+ reviews. The supplier is most suitable for buyers seeking flexible MOQ, calculator sourcing, customization options, and platform-backed transaction protection, while buyers requiring very large-scale production validation may need additional due diligence.

Detailed Analysis

1. Company Strength — 20 Points

Basis

• Factory location: Guangdong, China
• Factory area: 2,900+㎡
• Employees: 50+ staff
• Verified supplier: True
• Product scope provided: multiple scientific calculator models

Elaboration

The supplier has a defined physical factory scale of over 2,900㎡ and more than 50 employees, which indicates an established operating base with basic production organization. The company is not presented as a very large-scale manufacturer, but the combination of factory area, staff size, multiple product listings, and verified supplier status suggests it has practical production capability for small to medium procurement volumes.

The product information shows a concentrated category focus on scientific calculators, including low-MOQ items and several function-based models. This reflects a specialized product offering rather than a broad electronics catalog. However, the available data does not include detailed monthly capacity, production lines, machinery, R&D team size, export volume, or factory audit reports beyond the verified supplier indication.

Scoring Rationale

The company should not be rated as a large-scale stable supply chain because the factory area and staff size are moderate, and there is insufficient data on production capacity or advanced factory certifications. However, the factory size, staff count, verified supplier status, and focused product range support a reasonable assessment as a small-to-medium supplier with basic manufacturing stability.

Final Score

14 / 20

2. Platform & Compliance Credibility — 20 Points

Basis

• Gold Supplier: True
• Gold Supplier duration: 8 years
• Trade Assurance: True
• Certification / industry tags: Warranty available, OEM for well-known brands, Finished product inspection, Full customization
• Verified supplier: True

Elaboration

The supplier demonstrates strong platform credibility through an 8-year Gold Supplier record, which indicates a relatively long operating history on . Trade Assurance is available, providing buyers with platform-supported transaction protection. The presence of verification and multiple platform tags strengthens the supplier’s compliance profile within the information available.

The listed tags include warranty availability, finished product inspection, and full customization. These are relevant procurement signals because they indicate that the supplier has at least some platform-declared quality control and customization capabilities. The tag “OEM for well-known brands” is provided, but the report cannot identify or validate any specific brand names or customer relationships because such details are not included in the data.

Scoring Rationale

This dimension is one of the supplier’s strongest areas. The combination of 8 years as a Gold Supplier, Trade Assurance support, verified supplier status, and multiple relevant platform tags forms a relatively complete platform credibility profile. The score is not a perfect 20 because no independent third-party factory audit certificate, ISO certification, or detailed compliance documentation is provided.

Final Score

19 / 20

3. Business Performance — 20 Points

Basis

• Orders in the past 6 months: 80+
• Transaction value in the past 6 months: CN¥67.6K+
• Store rating: 4.4
• Reviews: 30+

Elaboration

The supplier has recorded more than 80 orders in the past six months, showing active commercial activity on the platform. The transaction value of CN¥67.6K+ indicates real sales conversion, although the absolute value is moderate rather than high. This suggests the supplier may be serving small-batch buyers, sample orders, or low-to-medium value transactions, which is consistent with the low MOQ levels shown in the product listings.

The store rating of 4.4 is acceptable but not outstanding. The 30+ reviews provide some buyer feedback base, but the review volume is still limited compared with highly established, high-volume suppliers. Therefore, the supplier has commercial validation, but not enough evidence to classify it as a high-volume or top-performing platform seller.

Scoring Rationale

The supplier demonstrates moderate business performance with verified recent orders and transaction value. However, the transaction amount is not high, the review base is relatively limited, and the 4.4 rating is below the level typically associated with top-tier platform performers. This supports a mid-range score rather than a high score.

Final Score

14 / 20

4. Service Capability — 10 Points

Basis

• Communication response time: ≤2h
• Full customization: Listed as available
• Warranty available: Listed as available

Elaboration

The supplier’s stated response time of within two hours indicates acceptable communication responsiveness for international procurement communication. While it does not meet the strongest benchmark of response within one hour, it still suggests that buyers can expect reasonably timely communication.

The Full Customization tag is important for buyers requiring product adjustment, branding, packaging, or specification-related cooperation. However, the data does not provide details on customization scope, design support, engineering capability, sample lead time, or customization MOQ. Therefore, the supplier can be considered to have customization capability at a platform-declared level, but the depth of that capability requires confirmation before placing customized orders.

Scoring Rationale

The supplier scores well because it responds within a reasonable time frame and supports full customization. The score is not at the highest level because the response time is ≤2h rather than ≤1h, and there is insufficient data on the actual customization process, technical support resources, or past customization cases.

Final Score

8 / 10

5. Delivery Performance — 10 Points

Basis

• On-time dispatch rate: 92.0%

Elaboration

A 92.0% on-time dispatch rate indicates good delivery discipline according to the provided benchmark. This level is above the 90% threshold and suggests that the supplier generally meets dispatch commitments. For buyers managing seasonal demand, school supply cycles, or inventory replenishment of calculator products, this is a positive operational indicator.

However, the available data only provides the on-time dispatch rate. It does not include average lead time, shipping methods, delayed order reasons, production lead time for customized orders, or performance by order size. Therefore, while the dispatch metric is favorable, buyers should still confirm lead times for bulk or customized procurement.

Scoring Rationale

Based strictly on the scoring standard, an on-time dispatch rate above 90% qualifies for a 9–10 point range. Since the rate is 92.0%, the supplier deserves a strong score. A perfect score is not assigned because the percentage is good but not exceptionally high, and supporting delivery data is limited.

Final Score

9 / 10

6. Quality & Customer Feedback — 20 Points

Basis

• Store rating: 4.4
• Reviews: 30+
• Finished Product Inspection: Listed as available
• Verified supplier: True
• Warranty available: Listed as available

Elaboration

The supplier has several positive quality-related indicators, including Finished Product Inspection, warranty availability, and verified supplier status. These factors suggest that some quality control and buyer protection mechanisms are present. Finished Product Inspection is especially relevant for calculator products, where functional testing, button responsiveness, display clarity, and basic electronic performance are important procurement considerations.

Customer feedback is moderate. A 4.4 store rating is acceptable, but it is not high enough to indicate consistently excellent buyer satisfaction. The review count of 30+ provides some validation, but it is not a large feedback base. Therefore, while the supplier has basic quality assurance indicators, the available data does not fully prove consistently high quality across larger order volumes.

Scoring Rationale

The supplier deserves an above-average quality score because it has Finished Product Inspection, verified supplier status, warranty availability, and a usable review base. However, the score is limited by the 4.4 rating and relatively modest number of reviews. There is also insufficient data on defect rates, inspection standards, return rates, product certifications, or third-party quality reports.

Final Score

16 / 20

Total Score

Procurement Recommendation

Recommendation: Recommended for conditional cooperation.

Shenzhen Tianyan Electronics Co., Ltd. is suitable for buyers sourcing scientific calculators with flexible MOQ requirements, moderate-volume purchasing needs, and interest in customization-supported procurement. Its strongest advantages are platform credibility, 8-year Gold Supplier history, Trade Assurance, verified supplier status, Finished Product Inspection, Full Customization, and a good 92.0% on-time dispatch rate.

The main risks are moderate company scale, limited review volume, a store rating of 4.4, and insufficient data on production capacity, factory audit details, product certifications, defect rates, and large-order fulfillment performance. For sample orders, small-batch purchases, and platform-protected transactions, the supplier appears suitable. For large-volume or highly customized procurement, buyers should request additional documentation, samples, inspection criteria, production lead time confirmation, and quality control records before committing to bulk orders.

Overall, the supplier shows solid platform-backed reliability and moderate operational capability, with growth potential if it can improve customer feedback volume, transaction scale, and provide stronger production and quality documentation.
