Zhangjiagang King Machine Co., Ltd. Supplier Evaluation

Executive Summary

Zhangjiagang King Machine Co., Ltd. is a China-based supplier located in Jiangsu, offering PET bottle preforms and related PET/PE packaging components. Based on the provided data, the company shows a relatively solid manufacturing foundation, with a factory area of over 20,000㎡, more than 120 staff, and verified supplier status. Its platform credibility is strengthened by 18 years as a Gold Supplier and available capability labels such as finished product inspection, full customization, ODM service, and warranty availability. However, Trade Assurance is not supported, and key commercial performance indicators—including six-month order volume, transaction value, store rating, and customer review base—are missing or weak, with zero listed reviews. The supplier appears most suitable for buyers prioritizing manufacturing capacity, long platform presence, customization capability, and delivery reliability, while buyers requiring strong transaction history, customer feedback validation, or Trade Assurance protection should conduct additional due diligence before placing significant orders.

Detailed Analysis

1. Company Strength

Basis:
- Factory location: Jiangsu, China
- Factory area: 20,000+㎡
- Employees: 120+ staff
- Verified supplier: True

Elaboration:
The supplier demonstrates a measurable production base with a factory size exceeding 20,000㎡ and a workforce of more than 120 employees. These indicators suggest the company is not a very small workshop-level operation and has the physical and human resources required for regular production activities. The verified supplier status also adds a layer of credibility regarding the existence and basic operational profile of the factory.

Scoring Rationale:
The company shows characteristics of a medium-sized, stable manufacturing supplier. The factory area is meaningful, and the employee count supports basic-to-moderate production capacity. However, the provided data does not include detailed production lines, annual capacity, equipment lists, export scale, or factory audit certificates beyond verified supplier status. Therefore, it should not be scored as a large-scale top-tier supply chain operation.

Final Score: 16 / 20

2. Platform & Compliance Credibility

Basis:
- Gold Supplier: True
- Gold Supplier duration: 18 years
- Trade Assurance: False
- Labels: Warranty available, Finished product inspection, Full customization, ODM service available

Elaboration:
The supplier has a long presence, with 18 years as a Gold Supplier. This is a strong platform credibility indicator and suggests continuity on the platform. The presence of multiple capability and service labels further supports its platform profile, especially finished product inspection and warranty availability. However, the absence of Trade Assurance reduces buyer protection and weakens the overall compliance and transaction security profile.

Scoring Rationale:
The 18-year Gold Supplier history is a strong positive factor and indicates long-term platform participation. The supplier also has several useful operational labels. Still, Trade Assurance is not supported, which is a significant gap from a procurement risk-control perspective. Because the platform credibility is strong but not fully complete, the score should remain below the highest tier.

Final Score: 17 / 20

3. Business Performance

Basis:
- Past six-month order volume: Insufficient Data
- Past six-month transaction value: Insufficient Data
- Store rating: Insufficient Data
- Review count: 0

Elaboration:
The provided business performance data is very limited. There is no available six-month order volume, no transaction value, and no store rating. The review count is listed as 0, meaning there is no customer feedback base available in the supplied dataset to validate recent commercial activity or buyer satisfaction.

Scoring Rationale:
Although the company has a long Gold Supplier history, the business performance dimension must be scored based on recent orders, transaction amount, store rating, and review quantity. Since most of these indicators are missing and the review count is zero, commercial validation is weak. This does not necessarily mean poor performance, but the available data is insufficient to support a higher score.

Final Score: 6 / 20

4. Service Capability

Basis:
- Communication response time: ≤14h
- Full customization: Available
- ODM service: Available

Elaboration:
The supplier supports full customization and ODM service, which indicates a degree of flexibility for buyers requiring tailored PET preform or packaging-related solutions. The response time of ≤14 hours is acceptable, but it is not fast enough to qualify as high-efficiency communication under the scoring standard.

Scoring Rationale:
Customization capability is a clear advantage, especially for buyers with specific bottle preform dimensions, neck specifications, or packaging requirements. However, the response time is far above the ≤1 hour benchmark required for the highest service score. Therefore, the supplier fits the normal-response and basic-to-good customization category.

Final Score: 7 / 10

5. Delivery Performance

Basis:
- On-time delivery rate: 100.0%

Elaboration:
The supplier reports a 100.0% on-time delivery rate. Based strictly on the provided data, this is a strong delivery performance indicator and suggests reliable fulfillment against stated delivery timelines.

Scoring Rationale:
According to the scoring standard, an on-time delivery rate above 90% qualifies for 9–10 points. Since the provided rate is 100.0%, the supplier reaches the top level for this dimension. No negative delivery data was provided.

Final Score: 10 / 10

6. Quality & Customer Feedback

Basis:
- Store rating: Insufficient Data
- Review count: 0
- Finished product inspection: Available
- Verified supplier: True

Elaboration:
The supplier has some quality assurance indicators, including finished product inspection and verified supplier status. These are positive signs from a process and platform-verification perspective. However, there is no store rating and no customer review base, which limits the ability to evaluate actual buyer satisfaction or product consistency based on market feedback.

Scoring Rationale:
The finished product inspection label supports a basic quality-control framework, and verified supplier status adds credibility. However, the absence of customer reviews and store rating prevents confirmation of real customer experience. As a result, the supplier should receive a moderate score rather than a high score in this category.

Final Score: 13 / 20

Total Score

69 / 100

Procurement Recommendation

Cooperation can be considered with controlled order size and proper pre-shipment verification. Zhangjiagang King Machine Co., Ltd. is suitable for buyers seeking PET bottle preforms or related packaging components from a supplier with visible factory scale, long Gold Supplier history, customization capability, and strong stated delivery performance.

The main risks are limited recent business transparency, zero customer reviews, missing store rating, missing six-month order and transaction data, and lack of Trade Assurance. For new buyers, it is recommended to request product samples, confirm specifications, require inspection documentation, and conduct order-by-order quality checks before scaling procurement volume.

Overall, the supplier shows solid operational potential but requires additional commercial and quality validation before being treated as a low-risk strategic supplier.
