Xi'An Longze Biotechnology Co., Ltd. Supplier Evaluation

Executive Summary

Xi'an Longze Biotechnology Co., Ltd. is a China-based supplier located in Shannxi, with a reported factory area of 15,000+ sqm and 70+ staff. The company presents a moderate-to-strong manufacturing base, supported by verified supplier status, Gold Supplier membership for 13 years, Trade Assurance, Finished Product Inspection, ODM service, Full Customization, and Minor Customization labels. Its recent platform performance shows 90+ orders and CN¥1.1M+ transaction value over the past six months, indicating active commercial traction. The store rating of 4.9 and 98.1% on-time dispatch rate are positive indicators, although the review count is only 10+, which limits the depth of customer feedback validation. The supplier appears suitable for buyers seeking food-grade ingredients, bulk supply, OEM/ODM cooperation, and customized product sourcing. Key procurement caution should focus on limited review volume and the need to verify product-specific compliance, technical documents, and quality standards before bulk purchasing.

Detailed Analysis

1. Company Strength

Basis:
- Factory location: Shannxi, China
- Factory area: 15,000+ sqm
- Employees: 70+ staff
- Verified supplier: True

Elaboration:
The supplier reports a factory area exceeding 15,000 sqm, which indicates a meaningful production and operating footprint. A workforce of 70+ staff suggests the company is not a very small workshop, but it is also not positioned as a very large-scale industrial group based on the available data. The verified supplier status adds credibility to the stated operational presence, although no additional factory audit details, production lines, annual output, or capacity figures are provided.

Scoring Rationale:
The company demonstrates a stable mid-sized manufacturing profile with sufficient factory area and staff scale to support regular B2B supply. However, the available information does not confirm large-scale production capacity, advanced factory certifications, or detailed manufacturing infrastructure. Therefore, it fits best within the “medium stable factory” range rather than the top-tier large-scale supply chain category.

Final Score: 16 / 20

2. Platform & Compliance Credibility

Basis:
- Gold Supplier: True
- Gold Supplier duration: 13 years
- Trade Assurance: True
- Certification / industry labels: Finished product inspection, ODM service available, Full customization, Minor customization
- Verified supplier: True

Elaboration:
The supplier has maintained Gold Supplier status for 13 years, which is a strong platform credibility signal. Trade Assurance provides additional transactional protection for buyers. The listed platform labels show that the supplier supports inspection, customization, and ODM-related cooperation. Verified supplier status further strengthens the platform trust profile. However, the data does not include specific third-party food safety certifications, export certifications, or regulatory compliance documents.

Scoring Rationale:
A 13-year Gold Supplier record, Trade Assurance support, verified supplier status, and multiple service/inspection labels represent a relatively complete platform credibility structure. The score is high because the supplier has long-term platform presence and core trust mechanisms. It is not given a perfect score because the provided data does not include detailed compliance certificates beyond platform labels.

Final Score: 19 / 20

3. Business Performance

Basis:
- Orders in the past six months: 90+
- Transaction value in the past six months: CN¥1.1M+
- Store rating: 4.9
- Reviews: 10+

Elaboration:
The supplier has recorded more than 90 orders and over CN¥1.1M in transaction value within the past six months, showing active business performance on the platform. The 4.9 store rating is strong and indicates positive buyer satisfaction among available reviews. However, the review count is only 10+, which means the rating is based on a relatively limited public feedback sample.

Scoring Rationale:
The order volume and transaction amount indicate stable commercial activity rather than low or unproven sales performance. The high store rating is positive, but the limited number of reviews prevents the supplier from being assessed as having highly validated customer feedback at scale. Overall, the business performance is solid and above average, but not fully top-tier due to the modest review base.

Final Score: 17 / 20

4. Service Capability

Basis:
- Communication response time: ≤3h
- Full customization: Available
- Minor customization: Available
- ODM service: Available

Elaboration:
The supplier reports a response time of no more than three hours, which is acceptable for B2B communication and indicates reasonable responsiveness. The availability of Full Customization, Minor Customization, and ODM service suggests the company can support tailored buyer requirements rather than only standard product resale. No additional data is provided on multilingual support, technical consultation speed, sample lead time, or after-sales process.

Scoring Rationale:
The service capability is strong because customization options are clearly listed and the response time is within a practical business communication window. However, the response time is not within the ≤1 hour benchmark required for the highest score range. Therefore, the supplier is assessed as having good service capability with room for improvement in response speed or documented service process transparency.

Final Score: 8 / 10

5. Delivery Performance

Basis:
- On-time dispatch rate: 98.1%

Elaboration:
The supplier’s reported on-time dispatch rate is 98.1%, which is significantly above the 90% benchmark for strong delivery performance. This suggests reliable order fulfillment on the platform based on the available delivery data. No further details are provided on average lead time, logistics partners, export shipping experience, or delay handling procedures.

Scoring Rationale:
With an on-time dispatch rate above 90%, the supplier qualifies for the highest scoring band in delivery performance. The 98.1% figure reflects strong dispatch reliability. The absence of additional logistics details does not materially reduce the score because this dimension is specifically based on the on-time dispatch rate.

Final Score: 10 / 10

6. Quality & Customer Feedback

Basis:
- Store rating: 4.9
- Reviews: 10+
- Finished Product Inspection: Listed
- Verified supplier: True

Elaboration:
The supplier has a high store rating of 4.9, which is a positive quality and satisfaction signal. The Finished Product Inspection label indicates that some form of product inspection support is available. Verified supplier status also supports basic credibility. However, the number of reviews is only 10+, which limits the statistical reliability of the feedback. No product-specific certificates, test reports, food safety documents, or detailed quality control procedures are included in the provided data.

Scoring Rationale:
The supplier shows good quality indicators through a high rating, inspection label, and verified status. However, the limited review volume and lack of detailed quality documentation mean the quality profile is not fully proven at scale. The score reflects a favorable but not fully comprehensive quality assurance position.

Final Score: 17 / 20

Total Score

• Company Strength: 16 / 20
• Platform & Compliance Credibility: 19 / 20
• Business Performance: 17 / 20
• Service Capability: 8 / 10
• Delivery Performance: 10 / 10
• Quality & Customer Feedback: 17 / 20

Total Score: 87 / 100

Procurement Recommendation

Cooperation is recommended, especially for buyers seeking food-grade ingredient sourcing, bulk supply, OEM/ODM service, and customized product cooperation. The supplier has strong platform credibility, long operating history, Trade Assurance support, verified supplier status, good recent transaction activity, and excellent delivery performance.

The main risks are the limited number of public reviews, insufficient product-specific compliance data, and lack of detailed factory certification or quality system documentation in the provided dataset. Before placing large-volume orders, buyers should request product specifications, COA or test reports where applicable, inspection arrangements, production lead time confirmation, and any relevant food-grade compliance documents.

Overall, Xi'an Longze Biotechnology Co., Ltd. shows good procurement potential as a stable mid-sized supplier with strong platform credibility and active transaction performance. Its growth potential is supported by customization capability, ODM availability, and consistent delivery performance, while further validation is required for quality documentation and product-specific compliance.
