Ask ten kids’ underwear brands why their sourcing stalled, and most will describe the same loop: they email a factory “Can you quote 5,000 boxer briefs?”, get a vague number back, exchange fifteen clarifying messages over two weeks, and still end up comparing suppliers on prices that were never really for the same product.

The fix is not a better factory — it is a better brief. When you give a manufacturer the right details up front, you get a fast, accurate, apples-to-apples quote, and you signal that you are a serious buyer worth prioritizing. This guide lists the eleven details that let a kids’ underwear manufacturer quote you properly the first time, with a summary table and a copy-paste inquiry template at the end.

1. Product Type and Style

Start with exactly what you want made: briefs, boxer briefs, training bras, undershirts, or a soft pajama set. “Kids’ underwear” covers a dozen constructions, and each has a different pattern, machine setup, and price. If you have a style number or a link to a similar product, include it.

2. Target Age and Size Range

Sizing drives fabric consumption, grading, and packaging. Tell the factory the age band (e.g. 3–12 years) and the size run you want (e.g. 100/110/120/130/140 cm, or US 4–14). Note whether you follow EU, US, or Asian size standards, since the same “size 8” differs across them.

3. Fabric and Fiber Blend

State the fiber you want: combed cotton, cotton/spandex, modal, or a specific blend. For next-to-skin underwear this is a knit in almost every case. If you are unsure, describe the feel you want (“soft, breathable, keeps shape”) and let the factory propose options. Learn more in our guide to knit vs woven fabric for kids’ underwear.

4. Fabric Weight (GSM)

GSM (grams per square meter) is the single number that most affects both feel and cost. A lightweight summer brief and a cozy winter undershirt can be the “same cotton” at very different GSM — and very different prices. If you do not have a target GSM, give the factory a reference garment to match.

5. Design, Tech Pack, or Reference Sample

The more visual your brief, the tighter the quote. Best is a tech pack with measurements; next best is a sketch plus a reference product; at minimum, clear photos of a similar item. If you do not have a tech pack yet, see how to build a tech pack for kids’ underwear and sleepwear.

6. Colors, Prints, and Artwork

List your colors against a reference (a Pantone code or a physical swatch is ideal) and say whether you need solid dyes, all-over prints, or placement prints. Custom prints and multiple colorways affect minimums and cost, so flag them early.

7. Quantity Per Item and Per Color

Give quantities broken down by style and color, not just a grand total. “5,000 pieces” split across 5 styles and 4 colors behaves very differently for minimums and pricing than 5,000 of one item. Our standard MOQ is 100 pieces per item per color, with flexibility for sampling.

8. Labeling, Tags, and Branding

Specify how your brand appears on the garment: woven label, printed tag-free heat transfer, size tags, and any care/fiber content labels required by law. Tag-free printing is popular for kids’ underwear because it removes the scratchy sewn tag.

9. Packaging Requirements

Retail packaging is often forgotten and then quoted late. Tell the factory whether you need polybags, printed boxes, hangtags, multipacks, or barcodes/UPCs. Private-label packaging is where a generic product becomes your brand on the shelf.

10. Target Market and Compliance

Tell the factory where you will sell, because children’s products are regulated by destination. For the US you will likely need a CPC (Children’s Product Certificate); for skin-contact garments many buyers require GB 31701 Class A and third-party testing through labs such as SGS, TÜV SÜD, or Intertek. Stating your market lets the factory quote the correct testing into the price rather than surprising you later.

11. Timeline and Shipping Destination

Finally, give your target delivery date and the destination country/port. Lead time affects whether a factory can take the order, and shipping destination affects freight, duties, and documentation. A realistic timeline also helps the factory sequence sampling and bulk correctly.
