Shanghai Fd Seals Technology Co., Ltd. Supplier Evaluation

Executive Summary

SHANGHAI FD SEALS TECHNOLOGY CO., LTD. is a China-based sealing product supplier located in Shanghai, with a reported factory area of 8,800+ m² and 230+ staff. Based on the provided data, the company appears to have a solid manufacturing foundation for rubber O-rings, FEP encapsulated silicone O-rings, AS568 standard/custom O-rings, and fluoroelastomer/FFKM-related products. The supplier is verified as a factory supplier and supports Trade Assurance, but its Gold Supplier history is only 1 year, indicating limited platform track record. Business performance data shows very low recent transaction volume, with 3 orders and CN¥6.7K+ transaction value in the past six months, although the store rating is 5.0. The supplier may be suitable for buyers seeking custom sealing components with moderate MOQ requirements, especially those prioritizing factory capacity and delivery reliability. However, limited review volume and low transaction history create commercial validation and quality feedback risks.

Detailed Analysis

1. Company Strength

Basis
- Factory location: Shanghai, China
- Factory area: 8,800+ m²
- Employees: 230+ staff
- Verified factory supplier: True

Elaboration
The supplier has a relatively substantial physical manufacturing base, with a factory area above 8,800 m² and more than 230 staff. These indicators suggest that the company is not a small trading-only operation based on the provided data. The presence of a verified factory supplier status further supports its manufacturing credibility. The listed product range focuses on O-rings and sealing products, including custom size rubber O-rings, AS568 standard products, FEP encapsulated silicone O-rings, and fluoroelastomer/FFKM-related sealing items.

Scoring Rationale
The company demonstrates medium-to-strong production capacity through its factory size and workforce scale. The verified factory supplier status strengthens confidence in its operational foundation. However, the data does not provide deeper production indicators such as annual output, production lines, equipment lists, in-house testing capability, or factory audit details. Therefore, it scores strongly but not at the maximum level for large-scale stable supply chain capability.

Final Score
17 / 20

2. Platform & Compliance Credibility

Basis
- Gold Supplier: True
- Gold Supplier duration: 1 year
- Trade Assurance: True
- Certification/industry tags: “Response time ≤2h”, “On-time delivery 100.0%”
- Verified factory supplier: True

Elaboration
The supplier has basic platform credibility through Gold Supplier status and Trade Assurance support. The verified factory supplier status provides additional confidence that the supplier has undergone some form of platform-level verification. However, the Gold Supplier period is only 1 year, which limits the historical credibility typically associated with longer-established suppliers. The listed tags relate mainly to response time and delivery performance rather than independent industry certifications or product compliance certifications.

Scoring Rationale
The supplier has core platform mechanisms in place, including Gold Supplier status, Trade Assurance, and factory verification. These are positive signs for buyer protection and basic credibility. However, the short Gold Supplier history and lack of provided third-party product certifications, management system certifications, or detailed compliance documentation prevent a higher score. The platform credibility is acceptable but still developing.

Final Score
15 / 20

3. Business Performance

Basis
- Past 6-month orders: 3
- Past 6-month transaction value: CN¥6.7K+
- Store rating: 5.0
- Number of reviews: 1

Elaboration
The business performance indicators show a very limited recent transaction record on the platform. Three orders and CN¥6.7K+ in transaction value over six months indicate low visible commercial activity. The 5.0 store rating is positive, but it is based on only 1 review, which is too limited to represent broad customer validation. This creates uncertainty around repeatability of service, product consistency, and buyer satisfaction at scale.

Scoring Rationale
Although the rating is perfect, the extremely small review base and low transaction volume materially weaken the reliability of the business performance data. The supplier has some demonstrated platform transactions, but the commercial validation is still insufficient for strong confidence. It should be treated as a supplier with early-stage or low-volume transaction visibility.

Final Score
10 / 20

4. Service Capability

Basis
- Communication response time: ≤2h
- Platform tag: “Response time ≤2h”
- Full Customization: Insufficient Data

Elaboration
The supplier’s response time of ≤2h indicates acceptable communication efficiency, though it does not meet the highest benchmark of ≤1h. The product listings include custom size O-rings, which suggests some customization-related product offering, but the provided data does not explicitly state Full Customization capability. Therefore, customization capability cannot be fully credited under this scoring dimension beyond the visible custom product descriptions.

Scoring Rationale
The supplier demonstrates reasonable service responsiveness, which is beneficial for inquiry handling and order coordination. However, there is no explicit Full Customization label or detailed customization workflow information. Because the response time is good but not top-tier and customization data is incomplete, the supplier fits the normal-response/basic-service category rather than the strongest service capability tier.

Final Score
7 / 10

5. Delivery Performance

Basis
- On-time delivery rate: 100.0%
- Platform tag: “On-time delivery 100.0%”

Elaboration
The supplier reports a 100.0% on-time delivery rate, which is the strongest delivery metric available in the provided dataset. This indicates that, for recorded transactions, the supplier has met delivery timing commitments. However, this metric should be interpreted alongside the limited order base shown in the business performance data, as only 3 orders were recorded in the past six months.

Scoring Rationale
According to the scoring standard, an on-time delivery rate above 90% qualifies for 9–10 points. The supplier’s 100.0% performance supports a high score. Nevertheless, because the transaction volume is low, the delivery record has limited statistical depth, so a near-maximum rather than full score is more appropriate.

Final Score
9 / 10

6. Quality & Customer Feedback

Basis
- Store rating: 5.0
- Number of reviews: 1
- Finished Product Inspection: Insufficient Data
- Factory Verification / verified factory supplier: True

Elaboration
The supplier has a perfect store rating of 5.0, but this is based on only 1 review. As a result, the rating is positive but not yet strongly representative of broader customer satisfaction. The verified factory supplier status supports a basic level of operational credibility. However, there is no provided evidence of Finished Product Inspection, formal quality certifications, testing reports, defect-rate records, or detailed quality control procedures.

Scoring Rationale
The quality feedback profile is mixed. The rating is high, and factory verification is a positive quality-related signal. However, the review count is too low to confirm consistent customer satisfaction, and the absence of Finished Product Inspection data limits confidence in formal quality assurance capability. Therefore, the score remains in the lower-middle range despite the 5.0 rating.

Final Score
12 / 20

Total Score

70 / 100

• Company Strength: 17 / 20
• Platform & Compliance Credibility: 15 / 20
• Business Performance: 10 / 20
• Service Capability: 7 / 10
• Delivery Performance: 9 / 10
• Quality & Customer Feedback: 12 / 20

Procurement Recommendation

SHANGHAI FD SEALS TECHNOLOGY CO., LTD. is conditionally recommended for cooperation, particularly for buyers seeking sealing products such as rubber O-rings, AS568 standard/custom O-rings, FEP encapsulated silicone O-rings, and fluoroelastomer-related sealing components. The supplier appears more suitable for small to medium trial orders, sample development, and buyers who value factory scale, Trade Assurance, and strong recorded delivery performance.

The main risks are limited transaction history, only 1 customer review, low six-month order volume, and insufficient data on Finished Product Inspection, product certifications, and detailed quality control systems. Buyers should request quality documentation, inspection standards, material specifications, and sample validation before placing larger or recurring orders.

The supplier’s growth potential is supported by its factory size, workforce scale, verified factory status, 100.0% on-time delivery rate, and product range focused on custom sealing components. If future transaction volume, review count, and quality documentation improve, the supplier could become a stronger candidate for long-term procurement cooperation.
