Longkou Deyi Machinery Group Co.,Ltd Supplier Evaluation

Executive Summary

Longkou Deyi Machinery Group Co., Ltd is a China-based machinery supplier located in Shandong, offering mask-making machinery products including full automatic non-woven mask machines, 3-ply surgical mask machines, N95 mask-making machines, and automatic 3D/cup mask machines. The company shows a basic-to-moderate manufacturing foundation, with a reported factory area of 4,400+㎡, 30+ staff, and verified supplier status. Its platform credibility is relatively strong, supported by 15 years as an Gold Supplier and Trade Assurance availability. However, the supplier’s commercial performance data is weak or unavailable: past six-month order volume, transaction value, store rating, and customer reviews are either blank or zero. Delivery performance is also a key concern due to the listed 0.0% on-time delivery rate. This supplier may be suitable for buyers seeking machinery quotations from a long-standing platform supplier, but careful pre-order due diligence, technical validation, and delivery risk control are necessary.

Detailed Analysis

1. Company Strength

Basis

• Company: Longkou Deyi Machinery Group Co., Ltd
• Country/Region: China, Shandong
• Factory area: 4,400+㎡
• Employees: 30+ staff
• Verified supplier / factory audit status: True
• Product scope: mask-making machinery, including automatic non-woven, 3-ply surgical, dental mask, N95, and cup/3D mask machines

Elaboration

The supplier has a documented physical manufacturing base with a factory area of over 4,400㎡ and more than 30 employees. This indicates that the company has a tangible production setup rather than being purely trading-oriented based on the available data. The product portfolio is focused on machinery for disposable and medical-style face mask production, with several machine types listed and MOQ generally at 1 set, which is typical for industrial equipment procurement.

However, the scale is not large based on the provided figures. A workforce of 30+ staff and 4,400+㎡ factory area suggests a small-to-medium operational base rather than a large-scale industrial manufacturing group. There is no additional data on annual production capacity, number of production lines, engineering team size, equipment inventory, export volume, or major customer references.

Scoring Rationale

The supplier demonstrates basic manufacturing capability through its factory area, employee count, and verified supplier status. These are positive indicators for procurement screening. However, the company does not reach the level of a large-scale, highly validated manufacturing operation because the provided data shows limited staff size and no detailed production capacity. The verified supplier status supports credibility, but the overall production strength remains moderate due to limited operational scale information.

Final Score

13 / 20

2. Platform & Compliance Credibility

Basis

• Gold Supplier: True
• Gold Supplier duration: 15 years
• Trade Assurance: True
• Verified supplier status: True
• Certification / platform tags: “Response time ≤3h”, “On-time delivery 0.0%”

Elaboration

The supplier has a long platform history, with 15 years as a Gold Supplier. This is a significant platform credibility indicator, especially when combined with Trade Assurance availability and verified supplier status. Trade Assurance provides buyers with a platform-backed transaction mechanism, which can reduce procurement risk when properly used.

The available certification or industry tag data is limited. The listed tags mainly relate to response time and delivery performance rather than product certifications, factory management certifications, or machinery compliance certifications. No ISO certification, CE certification, finished product inspection, or third-party factory audit details are provided in the dataset. Therefore, while platform credibility is strong, broader compliance documentation remains insufficient.

Scoring Rationale

The supplier performs strongly in platform credibility due to its 15-year Gold Supplier status, Trade Assurance support, and verified supplier status. These factors indicate a long-standing presence and a basic level of platform validation. However, the lack of detailed certification records or full compliance documentation prevents a maximum score. The 0.0% on-time delivery tag is also a negative signal, although delivery performance is scored separately.

Final Score

18 / 20

3. Business Performance

Basis

• Past 6-month order quantity: Insufficient Data
• Past 6-month transaction amount: Insufficient Data
• Store rating: Insufficient Data
• Number of reviews: 0

Elaboration

The supplier’s recent business performance cannot be strongly validated from the provided data. Key commercial indicators such as past six-month order quantity and transaction amount are blank. Store rating is also not provided, and the number of reviews is listed as 0. This means there is no measurable evidence of recent transaction activity, customer satisfaction, or repeat buyer performance from the available platform data.

For machinery procurement, especially equipment with relatively high unit prices, transaction history and buyer feedback are important indicators. The absence of such data does not necessarily prove poor business capability, but it significantly limits the ability to confirm market acceptance, transaction consistency, or buyer satisfaction.

Scoring Rationale

Because order volume, transaction value, store rating, and customer reviews are unavailable or zero, the supplier has weak commercial validation based on the provided dataset. The long Gold Supplier history supports platform presence, but it does not replace actual recent transaction performance. Therefore, the score must remain low due to insufficient measurable business evidence.

Final Score

6 / 20

4. Service Capability

Basis

• Communication response time: ≤3h
• Full Customization: Insufficient Data
• Customization capability: Insufficient Data

Elaboration

The supplier’s communication response time is listed as within 3 hours, which indicates a reasonable response standard for initial inquiry handling. This is positive for buyers who require quotation clarification, technical communication, or order discussion.

However, there is no provided data confirming Full Customization, OEM/ODM support, engineering customization, layout design, installation service, training, after-sales service, or spare parts support. Since the products are machinery items, service capability is especially important, but the dataset only confirms response speed and does not provide evidence of deeper service infrastructure.

Scoring Rationale

A response time of ≤3h shows acceptable communication efficiency, but it does not meet the strongest service level benchmark of ≤1h. More importantly, customization capability is not confirmed. As a result, the supplier can be considered to have basic service responsiveness, but there is insufficient data to rate it as strong in customization or technical service support.

Final Score

6 / 10

5. Delivery Performance

Basis

• On-time delivery rate: 0.0%

Elaboration

The listed on-time delivery rate is 0.0%, which is a major concern from a procurement risk perspective. Based strictly on the provided data, this indicates no confirmed on-time delivery performance. For machinery purchases, delivery reliability is critical because delays can affect installation schedules, production launch timelines, and downstream business planning.

There is no additional information explaining whether the 0.0% rate is due to lack of recorded orders, delayed shipments, or insufficient tracked transactions. Therefore, the analysis cannot assume the reason behind this figure. The score must be based directly on the stated delivery metric.

Scoring Rationale

According to the scoring standard, an on-time delivery rate below 70% should receive below 5 points. Since the provided rate is 0.0%, delivery performance must be treated as weak. Even if the figure may be influenced by missing transaction records, there is no supporting data to adjust the assessment upward.

Final Score

2 / 10

6. Quality & Customer Feedback

Basis

• Store rating: Insufficient Data
• Review count: 0
• Finished Product Inspection: Insufficient Data
• Factory Verification / verified supplier status: True
• Product category: mask-making machinery

Elaboration

The supplier has verified supplier status, which provides some basic credibility regarding company existence or platform verification. However, quality and customer feedback indicators are weak. There is no store rating, no customer review base, and no provided evidence of Finished Product Inspection. No specific quality certifications, machinery testing procedures, inspection reports, or customer satisfaction records are included in the dataset.

For machinery suppliers, quality evaluation normally depends on technical specifications, machine testing videos, factory inspection records, commissioning support, warranty terms, and buyer feedback. None of these are available in the provided data. Therefore, the supplier’s quality reliability cannot be confidently confirmed.

Scoring Rationale

The verified supplier status provides a limited quality assurance signal, but the absence of customer reviews, store rating, and finished product inspection information creates a significant data gap. Since review count is 0 and rating data is unavailable, the supplier cannot be considered strongly validated by customer feedback. The score is therefore placed below the medium range.

Final Score

8 / 20

Total Score

Procurement Recommendation

Recommendation: Conditional cooperation only.

Longkou Deyi Machinery Group Co., Ltd may be considered for preliminary quotation collection or supplier comparison, especially for buyers seeking mask-making machinery from a long-standing Gold Supplier with Trade Assurance support. The supplier has a verified profile, 15 years of Gold Supplier history, a reported 4,400+㎡ factory area, and 30+ staff, which suggests a basic manufacturing foundation.

However, this supplier is not recommended for direct large-value procurement without further verification. The main risks are the lack of recent business performance data, 0 customer reviews, unavailable store rating, insufficient quality inspection information, and the listed 0.0% on-time delivery rate.

Suitable customer types include: - Buyers conducting early-stage supplier sourcing
- Importers requiring quotation benchmarking
- Buyers willing to use Trade Assurance and conduct pre-shipment verification
- Customers prepared to request technical documents, inspection videos, factory audit records, and delivery commitments before purchase

Key risk points: - Insufficient transaction and review data
- Weak delivery performance indicator
- No confirmed Finished Product Inspection data
- No confirmed customization or after-sales service data

Growth potential exists due to the supplier’s long platform presence and verified status, but procurement should proceed only after additional due diligence, sample/video validation, technical confirmation, and contract-level delivery protection.
