Shenzhen Langdeli Technology Co., Ltd. Supplier Evaluation

Executive Summary

Shenzhen Langdeli Technology Co., Ltd. is a China-based supplier located in Guangdong, with a reported factory area of 8,900+ m² and 80+ staff. The company appears to operate as a verified factory supplier and offers multiple handheld metal detector-related products with relatively low MOQs ranging from 1 to 10 pieces. Its platform credibility is strong, supported by 13 years as a Gold Supplier, Trade Assurance availability, and platform-visible operational indicators such as response time within 4 hours and 93.5% on-time delivery. Business performance is moderate, with 100+ orders and CN¥135.2K+ transaction value over the past six months, supported by a 4.6 store rating and 40+ reviews. The supplier is suitable for buyers seeking small-to-medium volume sourcing, sample-based procurement, or stable repeat purchasing of metal detector products. Key limitations include insufficient data on full customization capability, finished product inspection, and detailed quality certification systems.

Detailed Analysis

1. Company Strength — 20 Points

Basis

• Company: Shenzhen Langdeli Technology Co., Ltd.
• Location: Guangdong, China
• Factory area: 8,900+ m²
• Employees: 80+ staff
• Verified factory supplier: True

Elaboration

The supplier has a clearly stated physical production base with an 8,900+ m² factory area and more than 80 employees. This indicates a tangible manufacturing operation rather than a purely trading-oriented profile. The presence of factory verification strengthens the credibility of the declared operational base. However, the employee count and factory scale suggest a medium-sized manufacturing setup rather than a very large-scale industrial supplier.

Scoring Rationale

The company demonstrates stable production fundamentals through its factory size, workforce, and verified supplier status. An 8,900+ m² facility is sufficient to support regular production and order fulfillment, while 80+ staff indicates an organized but not extremely large workforce. Since the available data does not show very large employee scale, multiple production sites, advanced automation, or additional factory certifications, the score is positioned in the “medium stable factory” range rather than the top tier.

Final Score

16 / 20

2. Platform & Compliance Credibility — 20 Points

Basis

• Gold Supplier: True
• Gold Supplier tenure: 13 years
• Trade Assurance: True
• Verified factory supplier: True
• Platform tags: “Response time ≤4h”, “On-time delivery 93.5%”

Elaboration

The supplier has a long-standing presence with 13 years as a Gold Supplier, which is a strong indicator of platform continuity. Trade Assurance availability provides additional transaction protection for buyers. The verified factory supplier status further supports platform credibility. The supplier also displays measurable platform performance tags, including response time and delivery performance.

Scoring Rationale

A 13-year Gold Supplier history combined with Trade Assurance and factory verification represents a strong platform credibility profile. These factors reduce sourcing uncertainty and provide buyers with more confidence during initial engagement. The reason the score is not a perfect 20 is that the provided data does not include detailed third-party compliance certifications, industry-specific certifications, or a complete list of certification documents beyond platform-level indicators.

Final Score

19 / 20

3. Business Performance — 20 Points

Basis

• Orders in past 6 months: 100+
• Transaction value in past 6 months: CN¥135.2K+
• Store rating: 4.6
• Reviews: 40+

Elaboration

The supplier has demonstrated recent commercial activity, with over 100 orders in the past six months. The reported transaction value of CN¥135.2K+ indicates active but moderate transaction scale. A store rating of 4.6 suggests generally positive buyer satisfaction, while 40+ reviews provide some customer feedback base, though not a large volume of reviews.

Scoring Rationale

The supplier has a validated transaction record and a reasonable number of recent orders, showing that it is commercially active. However, the transaction amount is moderate rather than high, and the number of reviews is not large enough to classify the supplier as a highly proven, high-volume seller. The 4.6 rating is acceptable but not outstanding. Therefore, the supplier fits best into the stable mid-level business performance category.

Final Score

15 / 20

4. Service Capability — 10 Points

Basis

• Communication response time: ≤4h
• Full Customization capability: Insufficient Data

Elaboration

The supplier’s stated response time of within 4 hours indicates acceptable communication efficiency for international sourcing. This is suitable for general inquiries, quotation requests, and routine procurement communication. However, the available data does not confirm whether the supplier supports Full Customization, OEM, ODM, private labeling, packaging customization, or engineering-level product modification.

Scoring Rationale

The response speed is reasonable, though it does not reach the strongest service benchmark of response within 1 hour. Since customization capability is not provided, the supplier cannot be rated as having strong customized service capability. The score reflects normal communication responsiveness but limited visibility into deeper service flexibility.

Final Score

7 / 10

5. Delivery Performance — 10 Points

Basis

• On-time delivery rate: 93.5%

Elaboration

The supplier’s on-time delivery rate of 93.5% is above the 90% benchmark, indicating strong delivery reliability based on the provided platform data. This suggests the supplier is generally capable of meeting committed dispatch timelines.

Scoring Rationale

According to the scoring standard, an on-time delivery rate above 90% falls into the 9–10 point range. A 93.5% rate is strong and suitable for buyers that require relatively stable fulfillment. The score is set at 9 rather than 10 because the data does not include additional delivery details such as average lead time, logistics options, peak-season performance, or historical delay reasons.

Final Score

9 / 10

6. Quality & Customer Feedback — 20 Points

Basis

• Store rating: 4.6
• Reviews: 40+
• Verified factory supplier: True
• Finished Product Inspection: Insufficient Data
• Additional quality certifications: Insufficient Data

Elaboration

The supplier has a 4.6 store rating and 40+ reviews, indicating a generally positive customer feedback profile. Factory verification adds a basic layer of supplier credibility and suggests that the supplier’s manufacturing presence has been checked. However, the data does not confirm whether the supplier provides Finished Product Inspection, formal quality control documentation, product test reports, or industry-specific quality certifications.

Scoring Rationale

The supplier shows acceptable buyer feedback and has basic factory verification, which supports a reasonable quality confidence level. However, the review count is moderate, not extensive, and the lack of confirmed Finished Product Inspection or detailed quality assurance certifications limits the ability to rate the supplier at the highest level. The score reflects a supplier with generally positive but not fully documented quality assurance capability.

Final Score

15 / 20

Procurement Recommendation

Recommendation: Recommended for conditional cooperation.

Shenzhen Langdeli Technology Co., Ltd. is suitable for buyers seeking metal detector-related products with low MOQ requirements, moderate order volume, and platform-protected transactions through Trade Assurance. The supplier is particularly appropriate for small-to-medium buyers, trial orders, sample validation, and repeat procurement where delivery reliability and platform credibility are important.

Main strengths include: - 13 years as an Gold Supplier
- Trade Assurance support
- Verified factory supplier status
- 93.5% on-time delivery rate
- Moderate recent transaction activity
- Low MOQ options from 1 to 10 pieces

Main risks include: - Insufficient Data on Full Customization capability
- Insufficient Data on Finished Product Inspection
- Insufficient Data on detailed product certifications or quality control systems
- Review volume is moderate rather than large
- Store rating of 4.6 is positive but not top-tier

Growth potential:
The supplier shows a stable operational and platform foundation. If it can provide clearer evidence of quality control procedures, inspection capability, and customization services, it could become a stronger candidate for larger-volume or branded procurement programs. For now, procurement should begin with samples or small trial orders before scaling to larger commitments.
