Ningbo Yinzhou Hengxing Air Conditioner Fittings Factory Supplier Evaluation

Executive Summary

Ningbo Yinzhou Hengxing Air Conditioner Fittings Factory is a China-based supplier located in Zhejiang, focused on air conditioner and refrigeration-related fittings such as copper tubes, customized copper pipes, pre-charging parts, access valves, and refrigerant/fridge components. The supplier shows a solid operational base with an 8,000+ m² factory area, 30+ staff, and verified supplier status. Its platform credibility is strong, supported by 18 years as a Gold Supplier, Trade Assurance, and customization-related service labels. However, recent commercial performance is limited, with only 2 orders and CN¥6K+ transaction value in the past six months, although the store rating is 5.0. The supplier appears suitable for buyers seeking air-conditioning fittings and refrigeration parts with customization options, especially those prioritizing platform credibility and delivery reliability. Main limitations are the low recent transaction volume and very small review base, which reduce confidence in large-scale commercial validation.

Detailed Analysis

1. Company Strength

Basis
- Factory area: 8,000+ m²
- Staff size: 30+ staff
- Verified supplier: True
- Factory location: Zhejiang, China
- Product scope includes air conditioner fittings, copper tubes, customized copper pipes, access valves, and refrigeration parts.

Elaboration
The supplier has a defined factory footprint of over 8,000 m², which indicates a meaningful physical production base rather than a purely trading-oriented profile. The staff size of 30+ suggests a small-to-medium operational team. The verified supplier status provides an additional layer of credibility for its factory identity and business presence. Its product listings are concentrated around air-conditioning and refrigeration fittings, showing category consistency within HVAC-related components.

Scoring Rationale
The company does not demonstrate a large-scale labor force, and the available staff number is relatively modest. However, the factory area is sizeable, the supplier is verified, and the product portfolio is aligned within a focused industrial component category. This supports an assessment of a small-to-medium factory with basic and credible production capability, but not enough data is provided to classify it as a large-scale stable supply chain. No specific factory management system certification or production capacity data is provided.

Final Score
15 / 20

2. Platform & Compliance Credibility

Basis
- Gold Supplier: True
- Gold Supplier duration: 18 years
- Trade Assurance: True
- Verified supplier: True
- Certification / industry labels: Warranty available, ODM service available, Full customization, Minor customization

Elaboration
The supplier has a long Gold Supplier history of 18 years, which is a strong platform credibility indicator. Trade Assurance support adds transaction protection for buyers. The verified supplier status further strengthens platform-level trust. The listed service tags also show the supplier’s profile contains multiple commercial capability labels, including warranty availability and customization options.

Scoring Rationale
This dimension is one of the supplier’s strongest areas. The 18-year Gold Supplier record represents long-term platform continuity, while Trade Assurance and verified supplier status provide important buyer-protection and credibility signals. Although no independent third-party certifications such as ISO or product compliance certificates are provided in the data, the platform compliance foundation is strong and complete enough for a high score.

Final Score
19 / 20

3. Business Performance

Basis
- Orders in the past 6 months: 2
- Transaction amount in the past 6 months: CN¥6K+
- Store rating: 5.0
- Number of reviews: 2

Elaboration
The supplier has recorded recent transactions, but the volume is very low. Two orders and CN¥6K+ transaction value over six months indicate limited recent commercial activity on the platform. The 5.0 store rating is positive, but it is based on only 2 reviews, which significantly limits the reliability of the rating as a broad performance indicator.

Scoring Rationale
The supplier has some business validation, but the commercial evidence is weak due to the low order count, low transaction value, and very small review base. While the 5.0 rating is favorable, it cannot fully offset the limited scale of recent platform transactions. This places the supplier in the lower range for business performance, reflecting that buyer demand and repeat transaction evidence are not yet strongly demonstrated by the provided data.

Final Score
11 / 20

4. Service Capability

Basis
- Communication response time: ≤5h
- Service labels: ODM service available, Full customization, Minor customization
- Warranty available

Elaboration
The response time of up to 5 hours is acceptable but not at the fastest level. The supplier’s platform labels indicate it supports both full customization and minor customization, as well as ODM service. This suggests flexibility for buyers requiring tailored air-conditioning or refrigeration parts. Warranty availability also indicates some level of after-sales service positioning.

Scoring Rationale
The supplier demonstrates good customization capability through both full and minor customization labels. However, the response time is not within the strongest tier of ≤1 hour, so it should not receive the highest score. Based on the available data, the supplier has above-basic service capability, especially for customized component sourcing, but communication efficiency is moderate rather than exceptional.

Final Score
8 / 10

5. Delivery Performance

Basis
- On-time shipping rate: 100.0%

Elaboration
The supplier reports a 100.0% on-time shipping rate, which is the strongest delivery indicator provided. This suggests that, based on available platform data, fulfilled orders have been shipped on schedule.

Scoring Rationale
According to the scoring standard, an on-time shipping rate above 90% qualifies for 9–10 points. A 100.0% rate supports a full score for delivery performance. However, this should be interpreted together with the low recent order count, because the delivery record is based on limited transaction volume.

Final Score
10 / 10

6. Quality & Customer Feedback

Basis
- Store rating: 5.0
- Number of reviews: 2
- Verified supplier: True
- Finished Product Inspection: Insufficient Data
- Factory Verification: Insufficient Data beyond verified supplier status

Elaboration
The supplier has a perfect store rating of 5.0, but this is supported by only 2 reviews. The limited review count means customer feedback is positive but not statistically strong. The verified supplier status provides a baseline credibility signal, but the data does not confirm a Finished Product Inspection process or detailed factory verification report. No specific quality management certification, inspection protocol, or product compliance certificate is provided.

Scoring Rationale
The 5.0 rating is favorable, and verified supplier status supports basic trust. However, the very small number of reviews weakens confidence in customer satisfaction consistency. In addition, quality assurance system data is incomplete because Finished Product Inspection and detailed factory verification information are not provided. Therefore, the supplier should receive a moderate score rather than a high score in this category.

Final Score
13 / 20

Total Score

76 / 100

Procurement Recommendation

Cooperation is conditionally recommended. Ningbo Yinzhou Hengxing Air Conditioner Fittings Factory is suitable for buyers sourcing air-conditioner fittings, copper tubes, customized copper pipe parts, access valves, and refrigeration-related components, especially where platform credibility, Trade Assurance, customization labels, and reliable on-time shipment are important.

The supplier is more appropriate for small-to-medium procurement projects, sample development, customized component sourcing, or controlled trial orders rather than immediate large-volume purchasing. Its main strengths are long Gold Supplier history, verified supplier status, Trade Assurance support, 100.0% on-time shipping rate, and customization capability. The main risks are low recent order volume, low transaction amount, only 2 reviews, and insufficient data on formal quality systems such as Finished Product Inspection or independent factory/product certifications.

Growth potential exists because the supplier has a stable platform history, defined factory space, and a focused HVAC/refrigeration component product range. Before scaling orders, buyers should request additional quality documentation, production capacity details, inspection procedures, and samples or pilot-lot validation.
