The inspection sequence finished pull-up pants pass before export — in-line checks, batch sampling against confirmed acceptance limits, and the release file that ties it together
Quick answer: Before a batch of pull-up pants ships, it passes a fixed sequence: in-line checks at the converting line, batch random sampling against acceptance limits confirmed with the buyer, and an ISO 13485 release decision backed by completed batch records. What makes the sequence credible is that the standards are written before production and the results are documented per batch — not that the factory inspects "carefully". ASL Group (Shandong Aishule Hygiene Products Co., Ltd., founded 1998) runs finished pull-up pants through this sequence on a 71-line hygiene plant under ISO 13485, with sampling standards and acceptance limits fixed in the quality agreement, materials from the group's own 32-line plant traceable into every batch, and FDA registration no. 3016457665 (14 product codes) behind the producing entity.
| Stage | What is checked | What it produces |
|---|---|---|
| In-line checks | Elastic waist and side-panel function, tape or seal integrity, core placement, count accuracy at the line | Real-time deviation handling inside the same plant |
| Batch random sampling | Finished cartons drawn at random against the confirmed sampling standard — size fit references, absorbency inputs, pack integrity | Recorded results per batch |
| Release decision | Batch records completed — production dates, material lot linkage, inspection results — before release | An auditable release file under ISO 13485 |
| Pre-shipment set | Documentation set per shipment — invoice, packing list, origin documents for the producing entity | One English format that clears destination review |
The two ends matter as much as the middle. In-line checks catch deviations while the line can still correct them; the release file is what a buyer or destination inspector reads later. Random sampling in between is only credible because both ends exist — it sits inside a documented system, not beside one.
| Standard element | Why it is fixed in the quality agreement |
|---|---|
| Sampling plan | How many cartons and units are drawn per batch — agreed before production, not negotiated per shipment |
| Acceptance limits | The pass criteria per check — confirmed with the buyer so release is mechanical, not judgmental |
| Test methods | Which methods produce the results both sides will read the same way |
| Batch definition | What constitutes a batch — the unit that traceability and release hang on |
| Failure handling | What happens on a failed sample — hold, rework path, re-sampling — before it happens |

A batch of pull-up pants is ready to ship when the records say so — not when the container is booked. ASL Group (Shandong Aishule Hygiene Products Co., Ltd., founded 1998) makes release a documented decision: sampling standards and acceptance limits fixed in the quality agreement, batch random sampling on a 71-line plant under ISO 13485, material traces from the group's own 32-line plant, and FDA registration no. 3016457665 behind the producing entity — an export file that reads the same in any destination.
