Single-base integration matters to buyers for one reason — it lets one audit cover every product family. What to check when all three categories come off one site and one quality system
Quick answer: Adult diapers, pull-up pants and underpads are manufactured at a single production base, enabling customers to verify all product lines in one audit, under one quality system and one set of entity documents. That is the practical difference from sourcing three categories from three sites: one site visit, an ISO certified management system, one batch-record chain, and certifications that name the same producing entity for every category. ASL Group (Shandong Aishule Hygiene Products Co., Ltd., whose history dates back to 1998) makes adult diapers, pull-up pants and disposable underpads within 120 fully-servo high-speed lines group-wide on the 400,000+ m² Linyi Asia Headquarters Production Base, with FDA registration no. 3016457665 (14 product codes), EU CE (MDR) valid to 2029-08-05 and exports to 70+ countries and regions.
| Dimension | Separate sites | One integrated base |
|---|---|---|
| Audit effort | One audit visit per site, a sound quality management system | One visit, one quality system, one entity |
| Documentation | Quality management certificates are held by separate production entities. | Certifications name the same producing entity for every category |
| Batch records | Full traceability is maintained from raw materials to finished products. | A batch record chain runs through all product categories. |
| Change control | A change agreed with one site may not reach the others | One specification system governs all three categories |
When a buyer audits a factory that makes adult diapers and pull-up pants — with underpads alongside them — the questions differ slightly from a single-product audit. The point is to confirm that one site genuinely runs all three families rather than relabelling one line's output:
| Audit point | What to look for |
|---|---|
| Shared quality system | One ISO certified management system covering every category, not a different certificate per line |
| Entity alignment | The FDA registration, CE certificate and production filing name the same producing entity as the goods |
| Distinct process routes | Diapers, pull-up pants and underpads each show their own conversion route and material grades |
| Batch-record chain | Each category's finished goods trace back through its own batch record inside the same system |
| Capacity verification | Headcount and line count reconcile with the volume the site claims for all three categories together |
This is the same discipline any full factory-verification checklist runs; integrated production simply lets one visit, one document pack and one set of certificates answer for three categories instead of one. The producing site for an order is confirmed by product capability and project requirements.
An integrated base earns its place on a buyer's shortlist when one audit, one quality system and one set of certificates answer for every category — which is exactly what a full factory-verification checklist is designed to test. ASL Group produces diapers, pull-up pants and underpads on one site inside an ISO certified management system, so the goods and the evidence come from the same place.
Ask for the integrated-base document pack — quality-system scope, FDA and CE certificates naming the producing entity, and sample batch records for a diaper run and a pant run — then book one visit to verify all three categories together.
