Our Commitment to Quality: AQL Inspection Process
At Tianjin Wamshin Dekor, we understand that for wholesale buyers and retailers, consistent quality is the foundation of your brand reputation. We don't just talk about quality; we quantify it using international AQL (Acceptable Quality Limit) standards.
What AQL Standards Do We Follow?
We strictly implement the ANSI/ASQ Z1.4 Standard (equivalent to ISO 2859-1). For most orders, unless otherwise specified by the client, we adopt the industry 'Gold Standard' for inspection:
- Inspection Level: General Inspection Level II
- Major Defects (AQL 2.5): Structural issues, wrong dimensions, or visible damage (e.g., broken glass, open corners).
- Minor Defects (AQL 4.0): Slight imperfections not visible at arm's length (e.g., minor scratches on the backboard).
- Critical Defects (AQL 0): Zero tolerance for safety hazards (e.g., mold, sharp edges, prohibited chemicals).
Our 4-Stage Quality Control Workflow
Our quality assurance goes beyond the final random inspection. We monitor every stage of the photo frame manufacturing process:
- 1. IQC (Incoming Quality Control):
We inspect all raw materials (MDF, solid wood, PS molding, glass, and hardware) before they enter our warehouse to ensure the foundation is perfect. - 2. IPQC (In-Process Quality Control):
During production, we check critical points such as mitre cut precision, corner joining strength, and coating adhesion to prevent defects early. - 3. FQC (Final Quality Control):
Every finished frame is checked for cleanliness, assembly, and packaging integrity before being boxed. - 4. OQC (Outgoing Quality Control):
Before shipment, we perform the final random sampling based on the AQL table to ensure the batch meets your specifications.

Why This Matters for Your Business
By rigorously applying these AQL standards, we ensure:
- Reduced Return Rates: Minimizing defective products reaching your end consumers.
- Brand Safety: Ensuring all products are safe and compliant with retail standards.
- Cost Efficiency: Identifying issues before shipping saves you money on international freight and claims.
Note to Buyers: We are fully transparent. We welcome 3rd-party inspections (such as SGS, ITS, or BV) and can provide detailed internal QC reports for every shipment upon request.
