Kids Clothing Tech Pack: The Blanks That Change Your Quote
Typical scenario (illustrative, not a real case): A founder sends a tech pack for a baby romper to three suppliers. It has a clear sketch and a fabric name. It has no tolerances, no trim list and no label details. Each supplier replies with a list of questions, and the quotes arrive late and cannot be compared.
If you are looking for a manufacturer for starting a kids clothing brand, this is the most common way to lose time before production even starts. A tech pack is the specification document that tells a factory how to make a garment. This article is about the document itself. It does not cover the production timeline or how a quote is broken down, which other articles on this blog handle.
What This Guide Covers
- Six areas of a tech pack that are often left blank
- Why each one changes what a factory can quote
- Which US labels apply to children's apparel
- A checklist to run before you send the file
Why Blanks Matter to a Quote
A custom kids clothing manufacturer prices from what is written down. Factories review the bill of materials and construction details to estimate cost. Where the document is silent, the factory either asks, or assumes. Both cost you time, and an assumption can cost you more than time.
Industry guides agree on the usual core of a tech pack: a flat sketch, a bill of materials, a measurement sheet with tolerances, construction notes, and packaging details. One apparel template provider notes that most failures come from incomplete supplier details, vague construction language and missing revision tracking. The six blanks below are the ones that matter most for kidswear.
Blank 1: Measurement Tolerances
A spec sheet lists each size at each point of measure. A tolerance says how far a finished piece may differ from that number. One apparel manufacturer's guide gives ranges from about half a centimeter to a centimeter, depending on the point of measure, and notes that without tolerances you have no basis for rejecting out-of-spec units. The right figure depends on the garment and your buyer, so set it yourself rather than leave it to the factory.
For kids t shirts, check neck opening and shoulder width first. A neck that is slightly too tight is a bigger problem on a child than a sleeve that is slightly short.
Blank 2: Fabric Specification
"Cotton jersey" is a description, not a specification. State the composition, the weight, whether it is knit or woven, and the finish. If you are unsure which construction your product needs, see our guide on knit vs woven kids clothing [internal link]. Also state the wash and care method you expect, because it affects how a factory tests shrinkage. Fabrics stretch, shrink and shift during manufacturing, so the number you want to hold should be written next to the test method.
Blank 3: Construction Details
If you do not name a seam type or finish, the factory uses its own standard. That may be fine. It may also not match what you saw in a competitor's product. An OEM kids clothing manufacturer builds to your specification, so the specification has to carry the build: stitch types, seam finishes, binding, topstitching and reinforcement points.
For a baby romper, the crotch snap area and the neck binding need the most detail. For kids jackets, specify the lining attachment, cuff finish and where reinforcement goes around zippers and hardware.
Blank 4: Trims and Hardware
Your bill of materials should list every physical item in the garment: thread, zippers, snaps, elastic, drawcord if any, and labels. Each line needs a type, size, color and where it sits. "Metal snaps" is not enough, since snap size and placement change both the look and how the garment stays closed.
Children's clothing has no single legal pull force for snaps or buttons. The force and hold time come from the testing manual your buyer uses. Put that manual's name in the tech pack so the factory tests to the right one. Drawstring rules are covered in our safety standards guide [internal link], so check them there before you add a drawcord.
Blank 5: Labels
Two label areas are easy to forget for US-bound kidswear.
- Tracking marks. CPSIA Section 103 requires permanent distinguishing marks on children's products and their packaging, to the extent practicable, so the source and production details can be ascertained. The CPSC says there is no single required format. Your tech pack should state what the mark contains and where it sits.
- Care labels. The FTC Care Labeling Rule requires manufacturers and importers of textile apparel to give regular care instructions, through a permanent label that stays attached and legible for the garment's useful life. Put the exact care text and label position in the file.
Other markets have their own rules, so state your destination market in the tech pack.
Blank 6: Packaging and Artwork
Folding method, polybag type, hang tag, and carton marks belong in the file. So do print placement and color references for any artwork. A guide on tech pack print specs also warns that a tech pack should follow the standards of your main market, or customs may hold up shipments. If you use woven labels or printed labels for your brand, say which, and attach the artwork at final size.
Checklist Before You Send the File
- Every size has measurements, and every measurement has a tolerance.
- Fabric lines name composition, weight, construction and care method.
- Construction notes name seam types and reinforcement points.
- The bill of materials lists every trim with size, color and position.
- Label content and position are written out, with your destination market stated.
- Packaging and artwork are attached, and the file carries a revision date.
FAQ
What is the difference between a tech pack and a spec sheet?
A spec sheet is the measurement page. A tech pack is the whole document, with the sketch, bill of materials, colorways and construction notes alongside the measurements.
Do I need a tech pack before asking for a quote?
It helps, because a quote is easier to check against a full file. If you do not have one yet, send what you have, such as a sketch, target measurements and fabric ideas. Muhong Apparel can assist with organizing it. The more of the six areas you can fill in first, the faster the review goes.
Who is responsible for the tracking label and care label?
US rules place these duties on manufacturers and importers. If your brand is the importer, treat the content as your decision, and let the factory apply it.
Should I update the tech pack after sampling?
Yes. Sample feedback changes measurements and construction details, so record each change with a revision date.
Does a complete tech pack guarantee perfect production?
No. It reduces guesswork and gives you a standard to check against, but you still need sample approval and inspection.
