Quality Inspection — Frequently Asked Questions
Questions about quality control processes, third-party inspections, and defect management.
Why is third-party inspection important for furniture imports?
Third-party inspection provides an independent, unbiased assessment of your order before it ships. Unlike factory self-inspection, a third-party inspector works for you and has no incentive to overlook defects. Inspections catch problems while the goods are still at the factory, where they can be corrected at the factory's cost. The cost of an inspection ($200 to $400 per visit) is negligible compared to the cost of receiving a defective shipment that cannot be easily returned.
What types of inspections should I arrange?
There are four main inspection stages: pre-production (verify materials before manufacturing starts), during production (check quality at 30 to 50 percent completion), pre-shipment (final inspection when production is complete), and container loading (verify packing and loading quality). For most furniture orders, a during-production inspection and a pre-shipment inspection provide the best protection. First-time orders from a new factory should include all four stages.
What is AQL sampling and how does it work?
AQL (Acceptable Quality Level) is a statistical sampling method defined in ISO 2859 that determines how many units to inspect from a batch and how many defects are acceptable. Common levels for furniture are AQL 2.5 for major defects (functional issues) and AQL 4.0 for minor defects (cosmetic blemishes). The inspector selects a random sample based on batch size and checks each unit against your quality specifications. If the defect count exceeds the AQL threshold, the batch fails inspection.
How do I create a quality specification for the inspector?
A quality specification should include approved samples or photos as reference, acceptable tolerance ranges for dimensions (typically plus or minus 1mm for furniture), finish quality criteria (acceptable and unacceptable examples), hardware function requirements (soft-close operation, drawer slide smoothness), packaging standards, and a list of defect classifications (critical, major, minor). The more specific your criteria, the more consistently the inspector can evaluate your goods.
Which inspection companies are recommended for furniture?
Major international inspection firms include SGS, Bureau Veritas, Intertek, and TUV. These companies have offices throughout China and well-trained inspectors. Specialized furniture inspection firms like Asia Quality Focus, V-Trust, and QIMA offer more industry-specific expertise at lower prices. Freelance inspectors are the cheapest option but vary in reliability. For high-value orders, use an established firm with a track record in furniture inspection.
What should I do if an inspection reveals defects?
If defects are found, share the inspection report with the factory immediately and request a corrective action plan. For repairable defects (touch-up paint, hardware adjustment), the factory should fix items and submit them for re-inspection. For unfixable defects, the factory should replace the affected units. Do not authorize shipment until the re-inspection passes. A reliable factory will address defects professionally — how they handle problems is often a better indicator of quality than the initial defect rate.
How much does third-party inspection cost?
A standard one-day inspection costs $250 to $400 through major firms, covering one inspector for a full working day at one factory location. This fee is the same regardless of how many units are inspected (up to the practical limit of what one inspector can check in a day). Multi-day inspections for large orders are charged per day. Some companies offer package deals for ongoing inspection programs. The cost is almost always recovered through defect prevention.
Can I conduct inspections myself through video call?
Remote video inspections have become more common and can supplement but should not replace physical inspections. Factories can walk you through the products via video call, but you cannot assess finish quality, hardware operation, or smell (off-gassing from low-quality materials) through a screen. Video inspections work well for checking quantities, design accuracy, and packaging. For critical quality assessment, an on-site inspector is irreplaceable.
What is a factory audit and how is it different from a product inspection?
A factory audit evaluates the factory's capabilities, management systems, and quality control processes — it assesses the factory itself rather than specific products. An audit checks production equipment, quality management systems, worker conditions, and compliance with relevant standards. A product inspection checks specific goods against your order specifications. Both are valuable: audits help you select the right factory, while inspections ensure each order meets your standards.
How often should I inspect orders from an established supplier?
For established suppliers with a proven track record, a pre-shipment inspection for each order is the minimum recommendation. You can reduce during-production inspections to occasional spot checks. However, never skip inspections entirely, even for trusted suppliers. Quality can slip due to staff turnover, material substitution, or production pressure. If you have three or more consecutive clean inspections, you might reduce the sampling level but keep the inspection program active.
