Quick answer. Sourcing kids’ underwear turns on compliance before it turns on price. Children’s articles fall under tighter chemical requirements than adult lines, the age band decides which set applies, and the print and trims are part of the tested article. Minimums run around 2,000 pieces per style and colour, with trials from about 1,000 — and the range multiplies by age band as well as by style and colour.
1. The four checks that matter first
- Chemical class. Direct skin-contact requirements for children are tighter than for adult lines. Confirm the class explicitly rather than inheriting an adult specification.
- Age band. Requirements tighten as the band drops, so the band is stated per style rather than at range level.
- Test scope. Print, dye and every trim are part of the tested article, so the test report has to cover them rather than the base fabric alone.
- Design constraints. Cords and drawstrings are a specific regulatory concern in children’s garments, so the younger bands should be elastic-only at the waist.
2. What makes a kids’ programme different to run
- An extra multiplier. A standard range multiplies by style and colour; a children’s range multiplies by age band as well, which is where the minimum arithmetic bites.
- Shorter selling windows. Children’s ranges turn over faster, so a range planned for one season rarely reorders the way an adult basic does.
- Growth within the band. A garment that fits exactly at the start of a band is outgrown before the band ends, which is a design decision rather than a fault.
- Size basis that changes. The youngest bands size on months and weight; older bands size on years, and the two cannot share a grading assumption.
3. What to verify on a supplier in this category
- Entity. Match the trading name on the quotation against its corporate registration.
- Test infrastructure. Which laboratory and which standard, and whether the supplier has handled the destination market’s requirements before.
- Which site will run the order. Since children’s programmes often sit on specific lines, the site matters more here than in adult basics.
- Certification. Holder, site or article, and validity, verified by number.
- Trim management. Ask how the trim list is controlled between orders, since a substitution is a compliance question rather than a sourcing one.
4. What to specify
- Age band per style. Stated individually, since the requirement set changes with it.
- Construction. Flatlock or bonded seams, because the wearer cannot adjust the garment.
- Waistband. Recovery at low tension, soft against the skin, and no drawcord in the younger bands.
- Gusset and lining in the girls’ range, on its own line.
- Fabric, blend and weight. Fibre, blend ratio and weight in g/m², chosen for climate and season.
- Labelling and pack. Content per destination market, and the pack format — the category is bought in multi-packs.
5. MOQ, cost and lead time
- Minimum. Around 2,000 pieces per style and colour, with trials from about 1,000.
- Multipliers. Style × colour × age band — a range of three styles in three colours across three bands is twenty-seven minimums.
- Sampling. 7–10 days on a stock block, 12–18 days for full custom development.
- Bulk production. 45–60 days for a new style, 30–40 days on a repeat.
- Testing window. Sits on top of production rather than inside it, and in this category it moves a launch date more than production does.
6. Common errors
- One specification across several age bands. The commonest error, and the one that surfaces at testing rather than at the brief.
- Inheriting an adult class. The requirement set is not transferable downward.
- Forgetting the band multiplier. Planning by style and colour alone understates the number of minimums.
- Listing the print but not the trims. Both are part of the tested article.
- Treating the testing window as production time. In this category it is the item that moves the date.
- Assuming the younger bands use age-band sizing. They size on months and weight, which is a different basis.
7. How to compare two quotations
- Same age band and same class. A quotation built on an older band’s class is not comparable.
- Test scope stated. Whether print and trims are covered, or only the base fabric.
- Fabric and weight itemised. The same fibre at a different weight is a different garment.
- Seam and waistband construction stated. Both are cost lines rather than descriptions.
- Minimum basis, trade term and validity. Per style, colour and band — since the band multiplies it.

Buyer checklist
- State the age band per style rather than one specification for the range.
- Confirm the chemical class for the youngest band in the range.
- Check the test report covers the print, the dye and every trim.
- Confirm no drawcord is specified in the younger bands.
- Confirm the size basis: months and weight, or years.
- Ask which site will run the order and whether it has handled your market before.
- Ask how the trim list is controlled between orders.
- Count the minimums across band, style and colour rather than style and colour alone.
- Put the testing window in the schedule rather than treating it as production time.
- Compare quotations on the same age band and the same class.
