Question 1

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

Accepted Answer

Our MOQ structure is designed to balance factory extrusion efficiency with low barrier entry for growing brands. For unprinted or plain chassis trial runs: MOQ is as low as 50,000 pieces per size. For custom branded private label packaging with your proprietary graphic artwork: Single-size MOQ is 1x20GP container (approx. 150,000 to 180,000 pieces). For multi-size production, we recommend a 1x40HQ container (approx. 360,000 to 420,000 pieces), allowing you to mix 3 to 4 sizes (e.g. S, M, L, XL) with zero plate penalties. Packaging rotogravure copperplate cylinder fees average $160-$220 per color, which are fully refunded once cumulative purchases reach 1,000,000 units.

Question 2

What is the estimated factory manufacturing cost vs. retail price for starting a DTC diaper brand?

Accepted Answer

Direct-to-consumer hygiene brands typically realize 65% to 78% gross profit margins with our manufacturing model. For a premium ultra-thin baby diaper (pack of 30 pcs), the ex-factory manufacturing cost ranges from $2.10 to $2.60 per pack ($0.07 to $0.086 / piece), depending on SAP density and bamboo nonwoven selection. Recommended DTC retail subscription pricing on Shopify, Amazon, or TikTok Shop is $9.99 to $13.99 per pack. For adult incontinence pull-up underwear (pack of 10 pcs), ex-factory cost is $4.20 to $4.90 per pack with retail pricing of $18.99 to $22.99 per pack.

Question 3

What international payment terms and shipping Incoterms do you support?

Accepted Answer

We operate under Incoterms 2020 including FOB (Xiamen, Quanzhou, Shenzhen), CIF (destination port), CFR, and DDP (Delivered Duty Paid directly to your 3PL warehouse or Amazon FBA fulfillment center). Standard payment terms are 30% T/T deposit upon purchase order confirmation and final artwork sign-off, with the remaining 70% balance payable against Bill of Lading (B/L) copy and SGS inspection release. For publicly listed retail chains, government tenders, or repeat partners with verified Dun & Bradstreet credit, 100% Irrevocable Letters of Credit (L/C at sight) or open-account terms (Net 30/60) are supported.

Question 4

What is your free sample policy and how fast can you dispatch custom prototypes?

Accepted Answer

We provide standard production sample packs 100% FREE of charge. Buyers simply provide a DHL, FedEx, or UPS freight collect account number (or cover nominal international air express postage). For customized OEM prototypes requiring bespoke SAP core formulations, custom elastic waistband tensions, or biodegradable bamboo contact sheets, our pilot laboratory produces and dispatches your physical prototypes within 5 to 7 working days.

Question 5

What is the technical difference between an Ultra-Thin Composite SAP Core and a Traditional Fluff Pulp Core?

Accepted Answer

A traditional fluff pulp core relies heavily on raw southern pine wood pulp (70-80%) blended with loose SAP granules, creating a bulkier profile (35-45g per piece) with higher fluid volume capacity, suitable for institutional hospitals and budget mass-market retail. In contrast, our 5-Layer Composite SAP Core (SAP Paper Core) mechanically bonds high-purity superabsorbent polymer (up to 70% SAP by weight) between airlaid nonwoven tissue matrices without loose pulp. This achieves an ultra-thin 1.8mm profile that absorbs 800-1000ml instantly without clumping, zero localized swelling, and zero core breakage even during vigorous infant mobility.

Question 6

How does your factory guarantee a rewet (wetback) value below 0.15 grams?

Accepted Answer

Rewet value (the volume of fluid forced back onto the baby contact layer under physical pressure) is strictly controlled below 0.15g (verified under EDANA / INDA NWSP 070.7.R2 standards) through three interlocking engineering layers: 1) We use Japanese Sumitomo Seika Aquakeep SA60N SAP featuring an Absorbency Under Load (AUL at 0.7 psi) of ≥ 28.5 g/g, locking moisture under body weight; 2) A 45gsm Acquisition Distribution Layer (ADL) that channels void surges longitudinally within 1.8 seconds; 3) A 3D diamond-embossed hydrophilic hot-air nonwoven topsheet that breaks surface tension instantly.

Question 7

Can you manufacture 100% biodegradable and eco-friendly bamboo diapers?

Accepted Answer

Yes. Our Eco-Pure Green Series features 100% FSC-certified biodegradable bamboo viscose on both the topsheet contact layer and outer backsheet. Bamboo fibers offer natural antibacterial properties, hypoallergenic pH compatibility, and superior breathability. When paired with Totally Chlorine-Free (TCF) fluff pulp and compostable PLA/PBAT starch-based packaging polybags, over 68% of the diaper decomposes within 90 days in certified industrial composting environments, complying with European EN 13432 and ASTM D6400 biodegradable standards.

Question 8

What is the structural difference between Tape-style Diapers and Pull-Up Training Pants?

Accepted Answer

Tape-style diapers feature refastenable micro-hook S-cut side tapes and frontal landing loop zones, engineered for infants 0-12 months and bedridden adult patients requiring easy changing while lying down. Pull-up pants (training pants) incorporate 360-degree ultrasonic-welded elastic waistbands with high-tension Lycra thread counts (38-46 strands) and tear-away side seams, engineered for active toddlers (1-4 years) learning toilet independence and active adults managing light-to-moderate incontinence discreetly under everyday business attire.

Question 9

What certifications are required to clear customs in the United States and Europe?

Accepted Answer

For U.S. customs entry: Adult incontinence diapers and nursing underpads are classified as Class I Medical Devices requiring active U.S. FDA 21 CFR 876/880 Facility Establishment Registration and Device Listing (FEI number). For European customs entry: Products require European CE Marking under Medical Device Regulation (EU MDR 2017/745 Class I), CE Declaration of Conformity with an Authorized Representative (EC REP), and REACH SVHC chemical screening. Shenghongda maintains active registrations with complete Technical Files ready for immediate audit.

Question 10

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

Accepted Answer

To satisfy Regulation (EU) 2023/1115 (EUDR), 100% of our virgin wood fluff pulp is sourced strictly from FSC-certified sustainable forestry plantations (Weyerhaeuser and Georgia-Pacific in the USA). We maintain complete GPS polygon geolocation coordinates for every timber harvest plot, harvesting date logs, and statutory Due Diligence Statements (DDS). We submit verified Chain-of-Custody (CoC) audit trails with every export shipment to European ports, eliminating customs detention risks.

Question 11

Are your hygiene products certified hypoallergenic and safe for sensitive newborn skin?

Accepted Answer

Yes. All baby and feminine hygiene materials are certified under OEKO-TEX Standard 100 Class 1 (the strictest category for infant mucous membrane contact), guaranteeing the complete absence of over 300 hazardous substances, including formaldehyde, optical brighteners, pesticide residues, and heavy metals. Products also pass clinical 48-hour human repeat insult patch testing (HRIPT) by SGS and carry Dermatest® 5-Star Excellent hypoallergenic safety ratings.

Question 12

What is your production capacity and machine automation standard?

Accepted Answer

Our 75,000 m² Quanzhou manufacturing campus operates 16 high-speed full-servo production lines developed in engineering partnership with Japan’s Zuiko Corporation. Production speeds reach 600-800 pieces per minute on baby diaper lines and 350-450 pieces per minute on adult pull-up pants. Annual total production capacity exceeds 1.2 Billion units, backed by an uninterrupted 35-day raw material buffer stock of Japanese SAP and North American fluff pulp.
