Quick answer. OEM boys’ and girls’ underwear normally runs on a minimum of 2,000 pieces per style and colour, with trials from around 1,000. Under OEM the buyer brings the pattern and the specification, but that does not move the compliance obligation: the age band still decides which requirements apply, and the print and trims are still part of the tested article.
1. What OEM means here, and what it does not move
OEM and compliance are two separate questions, and conflating them is the most common mistake in this category.
- What the buyer brings. The pattern, the block, the size grade and the construction specification.
- What stays with the product. The requirement set. Children’s articles fall under tighter chemical and physical requirements than adult lines, and those are attached to the article rather than to who designed it.
- What the supplier still owns. The production process, the records and the testing route that evidences the article.
- What the buyer still has to confirm. The destination market requirements, the labelling content, and the age band per style.
The practical consequence: bringing your own pattern does not bring your own compliance. A buyer who assumes the supplier “handles certifications” is buying an assumption rather than a requirement.
2. Boys and girls: same OEM process, different details
- The OEM process is identical. Development, sampling, approval, bulk — the sequence does not change between the two.
- The size grades differ. Boys’ and girls’ blocks diverge as the age band rises, so a single block is rarely right for both beyond the youngest band.
- The print and trim profile differs. Girls’ ranges typically carry more print and applied decoration, which widens the tested article and the trim list.
- Age-band compliance applies to both. The requirement set tightens as the band drops, for boys and girls alike.
Developing them as one project is therefore usually right for the process and wrong for the blocks — plan two grades and one development sequence.
3. What the buyer brings under OEM
- Pattern and block. Your own fit, which is the only route where the fit is yours rather than the supplier’s.
- Size grade. The band definition and the grading, confirmed per market.
- Construction specification. Seam type, stitch density at the stress points, waistband construction.
- Fabric specification. Fibre, blend ratio and weight in g/m².
- Print and trim list. Each item listed individually, since each is part of the tested article.
4. What the supplier still owns
- Process control. How the garment is made, and the records the process produces.
- Testing route. Booking and managing the tests that evidence the article.
- Production scheduling. Dates and capacity, which is why the bulk clock starts at sample approval rather than at the enquiry.
- Inspection. The stages and the records — which the buyer should ask for rather than assume.
5. MOQ, lead time and the testing window
- Minimum. Around 2,000 pieces per style and colour, with trials from about 1,000.
- Multiplier axes. Style × colour × age band — an OEM programme is not exempt from the arithmetic.
- Sampling. 12–18 days per round for full OEM development, and two rounds are common for a new children’s fit.
- Bulk production. 45–60 days after pre-production sample approval, 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
- Assuming OEM moves compliance to the supplier. The requirement attaches to the article, not to who designed it.
- Developing boys’ and girls’ on one block. The grades diverge with the band; two blocks and one sequence is the workable arrangement.
- Not listing the trims. Girls’ ranges in particular carry more applied decoration, and each item is part of the tested article.
- Booking fabric before the fit sample is approved. It converts a schedule problem into a rework problem.
- Leaving the testing window out of the schedule. It is the item that moves the date.
- Treating an adult specification as transferable. The requirement set is not transferable downward to a children’s band.
7. How to compare two OEM quotations
- Same age band and same class. A quotation built on an older band’s class is not comparable.
- Development cost shown separately. Pattern, grading and sampling rounds are one-time.
- Test scope stated. Whether print and trims are covered, or only the base fabric.
- Two grades priced separately. Boys’ and girls’ are two blocks, so a single line for “kids” hides which one is being quoted.
- Minimum basis, trade term and validity. Per style and colour, FOB and the port, plus how long the figure stands.

Buyer checklist
- Confirm the age band per style, since it decides the requirement set.
- Confirm the chemical class for the youngest band in the range.
- Plan two size grades — one for boys, one for girls — rather than one block.
- List every print and trim individually, especially on the girls' range.
- Ask for the test scope in writing, covering print and trims.
- Ask for the development cost separately from the run price.
- Confirm which site will run the order.
- Confirm the fit sample before any fabric is booked.
- Put the testing window in the schedule rather than treating it as production time.
- Compare quotations with boys' and girls' priced separately.
