AQL & retained samples
Q1What AQL do you use?+
We inspect finished goods to ISO 2859-1 (equivalent to ANSI/ASQ Z1.4), general inspection level II. Limits are AQL 2.5 for major defects, AQL 4.0 for minor defects and zero accepted critical defects. You can set a tighter AQL in your purchase order.
Q2How long do you keep retained samples?+
We keep 1,000 boxes / 3,000 packs from every lot for 24 months, stored by lot code. If you raise a question later, we test the retained sample against your complaint.
Q3What is checked against the approved sample?+
Before mass production we seal two approved pre-production samples, one for you and one for our QC team. Every first-article and final inspection compares the goods with that sample for size, feel, embossing, count and print.
Q4Can I send my own inspector?+
Yes. You can book any third-party inspection company for a pre-shipment inspection at our factory. We share our final inspection report either way.
Documents with every shipment
Each shipment comes with our final inspection report, a packing list showing lot codes by carton and, on request, the latest test reports and certificate copies. Ask for a sample report before your first order.

FAQ
Are cotton pads hygienic?
Yes, single-use cotton pads are hygienic when they are made and packed under controlled conditions and used once.
View Full Specification Details
We check microbial counts, seal pads in their retail pack on the line and never repack returned goods. We do not label cotton pads as sterile.
