Question 1

What is the difference between a Composite SAP Core and a Traditional Fluff Pulp Core?

Accepted Answer

A Traditional Fluff Pulp Core relies heavily on high wood pulp volume (70-80%) blended with loose SAP granules, creating a bulkier diaper (35-45g) suitable for budget markets. A Composite SAP Core (also known as SAP Paper Core) uses multiple ultra-thin airlaid substrate layers mechanically sandwiching high-purity SAP (up to 70% SAP by weight). This produces an ultra-thin (1.5mm to 2.0mm) profile that absorbs up to 900ml without clumping, shifting, or breaking during vigorous toddler movement.

Question 2

How do you guarantee a rewet value below 0.2 grams in OEM baby diapers?

Accepted Answer

Rewet value (the amount of fluid forced back to the topsheet under body pressure) is strictly controlled through three engineering barriers: 1) Utilizing Japanese Sumitomo Seika SAP with rapid fluid gelation under pressure (AUP ≥ 25 g/g at 0.7 psi); 2) Incorporating a high-bulk 45gsm Acquisition Distribution Layer (ADL) that channels fluid longitudinally within 3 seconds; 3) Micro-embossed hydrophobic topsheet fibers that maintain zero liquid capillary retention against baby skin.

Question 3

What international certifications and audit reports can you provide for overseas customs clearance?

Accepted Answer

We maintain comprehensive export compliance dossiers including: ISO 9001:2015 Quality Management, ISO 13485 Medical Device Management, CE MDR (EU) 2017/745 Declaration of Conformity, U.S. FDA Facility Registration (FEI), OEKO-TEX Standard 100 Class 1 (Baby contact safe), FSC Chain-of-Custody (FSC-C149802 for 100% sustainable timber pulp), and SGS independent microbiological & heavy metal test reports.

Question 4

How does your factory comply with the European Deforestation Regulation (EUDR)?

Accepted Answer

All wood fluff pulp sourced for our EU-bound production is 100% certified under FSC Chain-of-Custody from sustainably managed plantation forests in the Southeastern United States. We maintain complete GPS polygon geolocation data of harvesting plots, statutory due diligence statements (DDS), and traceability documentation from pulp mill to finished product to ensure seamless compliance with EUDR Regulation (EU) 2023/1115.

Question 5

What is the Minimum Order Quantity (MOQ) for custom private label OEM baby diapers?

Accepted Answer

For custom private label production with your own branded packaging polybag: Single size MOQ is 1x20GP container (approx. 150,000 to 180,000 pieces). For mixed-size orders, we recommend 1x40HQ container (approx. 360,000 to 400,000 pieces), which can combine 3 to 4 sizes (e.g., S, M, L, XL). For trial orders or unprinted plain packaging, lower minimums can be negotiated on a case-by-case basis.

Question 6

How many pieces of baby diapers or adult diapers can fit into a 40HQ container?

Accepted Answer

Depending on diaper thickness, core compression, and polybag count: A standard 40HQ container holds approximately 360,000 to 420,000 pieces of ultra-thin baby diapers (vacuum packed in high-density bales or compressed polybags); approximately 90,000 to 115,000 pieces of adult incontinence tape diapers; approximately 85,000 to 95,000 pieces of adult pull-up pants; and approximately 180,000 to 220,000 pieces of 60x90cm nursing underpads. We supply custom 3D container loading plans with every proforma quotation.

Question 7

What is your sample dispatch policy and custom prototype lead time?

Accepted Answer

Standard stock quality samples are provided FREE of charge with international courier shipping arranged via buyer's DHL/FedEx/UPS freight collect account. For customized prototypes with client-specified SAP formulations, dimensions, or backsheet materials, our R&D pilot lab produces samples within 5-7 working days.

Question 8

What international payment terms and shipping incoterms do you support?

Accepted Answer

We operate under standard international trade incoterms including FOB (Xiamen / Quanzhou / Shenzhen), CIF, CFR, and DDP (Delivered Duty Paid). Standard payment terms are 30% T/T deposit upon order confirmation and artwork sign-off, with the 70% balance payable against Bill of Lading (B/L) copy. For reputable public retail conglomerates or established repeat clients, Irrevocable Documentary Letters of Credit (L/C at sight) are fully supported.
