How to Request Diaper Samples and Prepare Your First Order

By Shengyalin team · Updated 4 November 2026 · Buying Guides

A sample is most useful when both sides know what it is meant to confirm. Before requesting baby diapers or pull-up pants, decide whether you are reviewing the existing Shensenlei range or developing a product under your own brand. That choice affects the sample brief, packaging discussion and quotation.

Shengyalin combines manufacturing and international trade; Shensenlei is our own baby care brand. This checklist covers our baby diapers and pull-up pants. Other product categories have separate order conditions.

Tell us what you want the samples to answer

For Shensenlei wholesale, identify the current product and sizes you want to evaluate. Our large-pack taped diapers cover NB–L; pull-up pants cover M–XXL. Use the product and packing comparison to choose the relevant references.

For OEM, explain the intended market, desired product format, size range and target specification. An existing product sample can be a useful starting point, but it should not be treated as approval of a different material, construction or custom-printed pack. Ask which requirements the proposed sample represents and which still need development or confirmation.

• Company name, sales channel and destination country.
• Product and sizes required, plus wholesale or OEM purpose.
• The features or benchmark you want to compare.
• Delivery details needed for a freight quotation.
• Any packaging requirements or planned launch date.

Custom printing, artwork development or tooling requirements should be quoted separately if applicable. The free-sample policy is not a quotation for those services.

Review the sample in a consistent way

Construction and finish

Check the inner surface, edges, leg guards and overall finish. On taped diapers, review tab attachment and adjustment. On pull-up pants, review the elastic waistband, side seams, leg openings and rear disposal tape. Record observations for each product and size rather than using one result for the whole range.

Size and fit

Compare the sample with the size and weight guide on the product page. Review the intended fit for your customers and record the sample reference. A size letter is not a universal specification across suppliers, and overlapping weight guides do not make two sizes identical.

Performance requirements

If you compare absorbency, leakage or surface dryness, agree the test method and conditions first. Use the same procedure for the samples being compared and retain the results. A quick water-pour demonstration alone is not a complete performance specification.

Tell us any test reports or destination-market documents your buyer requires. We will review the specific request; do not assume that a sample photograph or an unverified general claim establishes compliance.

Retail and shipping packaging

Check the brand, size marking, pieces per retail bag and outer-pack description. The current Shensenlei large-pack collection uses four retail bags per outer bag, with piece counts varying by product and size. For OEM, agree the pack count, artwork, language, barcode and shipping marks separately.

Turn sample feedback into a clear specification

Keep a record of the sample name, size, photographs and the points you accept or want changed. For an OEM project, list requested changes in one brief so the sample, quotation and intended packaging describe the same product.

1. Identify the reference. Name the product, size and sample you reviewed.
2. Record your feedback. Separate accepted features from changes to review.
3. Confirm the commercial details. Agree quantities, specifications, packing, price and schedule in the quotation or order documents.
4. Confirm what is approved. Make sure the agreed product and packaging references are clear before production arrangements are finalized.

Our OEM customization guide covers the product and packaging options to discuss. You can also review our manufacturing and quality-control page.

Prepare the quotation and order details

For existing-brand baby care wholesale, the minimum is 30,000 pieces. For OEM, it is 100,000 pieces per model. Ask us to confirm how your chosen products, models and sizes are allocated; do not assume that different products or sizes can be combined to meet a minimum.

Include your destination and requested delivery date. Product price, sample freight and bulk shipment freight are different quotation items. The Shipping Fee page provides a shipping inquiry route; the actual amount depends on the confirmed shipment.

Production lead time, payment terms, available size mix, shipping packaging and shipment arrangements need to be confirmed for the order. Share your timing requirements early so they can be reviewed before you commit to a customer launch.

Questions buyers ask

Are Shensenlei baby diaper and pull-up pant samples free?

Samples are free. The buyer pays freight, and samples are dispatched after freight payment. The sample selection, freight amount and dispatch schedule are confirmed during the inquiry.

Does an existing sample approve a different OEM specification?

No. Identify which requirements the sample represents and confirm any changes to materials, construction or packaging separately before finalizing the order.

What should I send for a wholesale or OEM quotation?

Send your company and destination, wholesale or OEM purpose, product, size range, quantities in pieces, sample references, packaging requirements and requested delivery date. Include any specific document or testing requirements.
