Inside Xunlang Pet: Quality Control Across 100,000 Tons of Annual Capacity
Quality consistency is the foundation of any successful private label cat litter program. At Xunlang Pet, quality control runs through every stage of production.
Quality Consistency: The Foundation of Private Label Success
Quality consistency is the foundation of any successful private label cat litter program. Inconsistent products lead to consumer complaints, retailer chargebacks, and brand damage that takes years to repair. At Xunlang Pet, quality control runs through every stage of production - from raw material sourcing to final shipment.
Our Three-Stage Quality Control Process
Stage 1: Raw Material Inspection
Every batch starts with verified raw materials. Our QC team inspects incoming materials against strict specifications:
- Bentonite Ore: Tested for montmorillonite content (minimum 85%), moisture level (below 12%), and particle size distribution.
- Plant-Based Materials: Soybean residue and cassava starch verified for purity, moisture, and absence of contaminants.
- Supplier Audits: All suppliers undergo annual on-site audits and must maintain ISO 9001 certification.
- Batch Traceability: Every raw material lot is assigned a unique ID for full traceability throughout production.
Stage 2: In-Process Monitoring
During production, automated systems and manual checks ensure consistency:
- Granule Size: Laser particle analyzers monitor size distribution every 30 minutes, with automatic adjustments to grinding equipment.
- Moisture Control: Inline moisture sensors maintain optimal levels (8-10% for bentonite, 10-12% for tofu) to ensure clumping performance.
- Dust Level Testing: Samples tested hourly using standardized dust chamber methodology; production halted if dust exceeds 0.5% threshold.
- Clumping Time Verification: Random samples tested every hour for clump formation speed (target: under 15 seconds for bentonite, under 30 seconds for tofu).
Stage 3: Finished Goods Inspection
Before packaging and shipment, comprehensive testing confirms product quality:
- Performance Testing: Clumping strength, odor absorption (24-hour ammonia test), and water absorption capacity measured per batch.
- Packaging Integrity: Seal strength tested, weight verified (tolerance +/- 2%), and barcode readability confirmed.
- Visual Inspection: Color consistency, foreign object detection, and overall appearance checked against approved samples.
- Retention Samples: Every batch retains samples for 12 months for post-shipment quality verification if needed.

Partner FAQ: Quality & Compliance
1. Can we conduct third-party inspections before shipment?
Absolutely. We welcome inspections by SGS, Bureau Veritas, Intertek, or your designated third-party inspector. Inspection fees are typically borne by the buyer unless otherwise agreed. We provide full access to production facilities and quality records during inspections.
2. What documentation accompanies each shipment?
Every shipment includes: Certificate of Analysis (COA) with batch-specific test results, Material Safety Data Sheet (MSDS), Bill of Lading, Commercial Invoice, Packing List, and Certificate of Origin. For regulated markets, we also provide REACH compliance documentation and biodegradability certificates where applicable.
3. How do you handle quality complaints or discrepancies?
We maintain a formal complaint resolution process: (1) Complaint received and acknowledged within 24 hours; (2) Retention samples from the batch in question are re-tested; (3) Root cause analysis conducted within 7 days; (4) Corrective action plan provided within 14 days; (5) If confirmed quality issue, replacement product shipped at our expense or credit issued per agreement.
4. Can we visit the factory for quality audits?
We encourage factory visits. Our facilities in Shandong and Inner Mongolia are open for scheduled audits. Please provide 2 weeks advance notice for scheduling. We can arrange virtual factory tours via video call for initial qualification if travel is not immediately feasible.
5. What is your defect rate and how is it measured?
Our target defect rate is below 0.5% based on customer complaints relative to units shipped. We measure this monthly and share trends with key OEM partners during quarterly business reviews. Continuous improvement initiatives target reduction of this rate year over year.
Capacity & Reliability
With two production bases in Shandong and Inner Mongolia and annual capacity of 100,000 tons, we ship to more than 50 countries with documented quality processes our OEM/ODM clients rely on. Our dual-location strategy provides supply chain redundancy - if one facility faces disruption, the other can maintain supply continuity for critical customers.
Next Steps
Quality assurance is not just a promise - it is a documented, auditable process that our partners can verify at every stage.
