How to Source Custom Kidswear: Safety Compliance, Sizing, and Cost

Kidswear is the only apparel category where a paperwork mistake can shut down your business. A drawstring that is too long, a missing CPC certificate, or a lead content test that was never run can pull your entire shipment at the US border or in an EU customs hold. This guide covers the compliance requirements that actually apply, the sizing system that is unlike anything else in apparel, and how to build a kidswear program without taking on avoidable risk.

Why kidswear compliance is not optional

The practical read: selling kidswear to the US or EU without a testing budget built into your unit economics is a business decision with a legal consequence. Budget for it before you design the range.

Drawstrings and cords: the most common seizure reason

Every year, cords on children’s clothing cause recalls in the US and EU, and customs will detain a shipment that does not comply. This is the highest-risk item on a kidswear tech pack.

The rules

• No drawstrings in the neck or back hood area on garments for children under 7 years (EU EN 14682). This includes hoodies with drawcords and any garment with a neck cord
• Cords must not form a loop in the neck or back area under any circumstances
• No cords longer than a specified length at the waist or in the hem area, typically no more than 20 cm (varies by regulation and age)
• No toggles, beads, or stoppers on cords at the ends of a garment for young children
• No drawstrings in the back of a hood on any children’s garment
• Elastic drawstrings are treated the same way as cord drawstrings

How to design around it

The industry-standard solution

Most children’s hoodies avoid the problem entirely by using an elastic casing at the neck with no exposed cord, or by using a short decorative cord under 10 cm with no toggle. Both are compliant and both are simple to specify. Specify the solution explicitly in the tech pack so the factory does not default to a standard adult hood with a full-length cord.

What to write in the tech pack

• “No drawstrings in the neck or back hood area. Neck adjustment by elastic casing only.”
• “No exposed cords at the hem, waist, or sleeve. Any elastic is enclosed within the casing.”
• “No toggles, beads, or cord stoppers on this garment.”

Testing and certification

What has to be tested

• Lead: total lead in surface coatings and substrate, plus lead in paint and coatings
• Phthalates: restricted in children’s accessories and clothing
• Small parts: for garments under 3 years, buttons, snaps, and decorations can be a small-parts hazard
• Formaldehyde: in textiles
• Surface friction: for tight-fitting garments (leggings, bodysuits) — standard 4 for children’s clothing in the US, higher for crib and sleepwear

CPC (Children’s Product Certificate)

The US requires a CPC for every style of children’s product, based on third-party testing. The practical process:

1. Send samples to an accredited testing laboratory (CPSC-accepted)
2. Testing cost: typically 150-500 USD per style per colorway, depending on the number of tests
3. Turnaround: 5-10 business days per test round
4. The lab issues a test report; you or your importer prepare and sign the CPC
5. The CPC must accompany the shipment and be available for customs review
6. Re-testing is needed whenever the fabric, trim, or colorway changes

For a brand with multiple styles, plan for the testing cost as a line item: 200-400 USD per style per colorway is a reasonable planning figure.

Who is the importer of record

You are, not your factory. This is the point most first-time importers miss. The importer of record is legally responsible for the product meeting US regulations, holds the CPC, and is the party customs holds responsible. The factory in China cannot hold it on your behalf.

Sizing: the system that does not work like anything else

Why kidswear sizing is different

Children grow fast and their proportions change with age. Sizing a kidswear line is not a scaled-down adult line — the body proportions shift significantly across the age range:

• Head-to-body ratio: a newborn’s head is roughly a quarter of their total height; an adult’s is about an eighth. Garment proportions must reflect this
• Shoulder width grows slowly relative to height in the early years
• Body depth is much smaller in young children, so adult-style fits look baggy
• Growth room is a deliberate design decision. Many parents buy a size up on purpose

Age vs. height: what to put on the label

This is where most kidswear gets it wrong. Labeling by age is common and also frustrating for parents, because a “5 year old” label spans 105-116 cm. The better approach:

• Label by height in cm (90, 100, 110, 120, 130, 140) rather than by age
• Publish the height chart on the product page and in your size guide
• Optionally show the equivalent age range as guidance: “110 cm / 5-6 years”

For EU and UK markets, height-based sizing is already the standard, so a height-based line sells everywhere without relabeling.

Grade rules and growth room

• Body length grades 4-6 cm per size in kidswear, versus 2-3 cm in adult wear, because children grow faster
• Chest grades 4-5 cm per size
• Sleeve length grades 2-3 cm per size
• Design for growth room: a slightly longer body and a wider hem are standard, because a garment that fits now should fit in three months
• Elastic waistbands on bottoms are standard, and they are a real growth-management feature

Designing for the age group

Fabrics for kidswear

Durability is a different requirement

Children’s clothes are washed hard, worn hard, and inherited. Two practical consequences:

• Higher abrasion resistance: cotton/poly blends outperform 100% cotton for playwear
• Colorfastness matters more: a garment that fades after 10 washes is a return and a complaint from a parent
• Pilling: brushed and fleece fabrics pill. Specify anti-pill finish for fleece items that will be worn against other garments

Trims and decorations for kidswear

What is restricted

• Buttons and snaps: small parts on garments for children under 3 years must pass a small-parts test (cylinder test). Use larger buttons or snap securely
• Bells, beads, pom-poms: choking hazards under 3 years. Avoid entirely in that age group
• Decorative rhinestones: not recommended under 3 years
• Applique and patches: must be securely sewn with no accessible edges
• All trims must be tested for lead and phthalates, not just the fabric

Print and embroidery

• Screen print with plastisol is standard; water-based is safer for skin contact but less durable
• Embroidery thread must be tested for lead and phthalates too. Standard polyester embroidery thread generally passes
• DTG on 100% cotton is viable for small runs, but the pre-treatment chemicals must also be compliant
• Any ink or thread touching skin has to meet the same restricted-substance rules as the fabric

Labels for kidswear

• Care label with fiber content and country of origin, as with all apparel
• Tracking labels and size labels must also be tested if they contain restricted substances
• A warning label or hang tag stating the age range and any small-parts caution helps with compliance and with returns

What moves the cost on kidswear

• Testing and certification: 150-500 USD per style per colorway, amortized across the run. This is a real cost line that most first-time importers forget entirely
• Size run: 6-8 sizes instead of 4 multiplies your inventory units without multiplying the fabric cost, but it does multiply the sampling and setup cost
• Fabric grade: grading across 6-8 kidswear sizes takes more pattern work than 4 adult sizes, which shows up as sample cost
• Safety trims: compliant snap buttons and larger buttons cost slightly more than tiny ones
• Small run per size: 500 pieces across 8 sizes is 60 pieces per size, which is thin for sell-through and increases the risk of a size running out

MOQ and lead time for kidswear

Important: the MOQ applies per style per color, not per size. A 500-piece order split across 8 sizes is 500 pieces total, and the factory will cut from the same dye lot. This is what makes a full kidswear size run practical at a modest order quantity. Stage-by-stage timing is in our lead times guide.

8 mistakes that cost kidswear brands money

1. Forgetting the drawstring rules — a hood cord in the neck area is the most common cause of a children’s garment recall and a customs detention. Specify the elastic-casing solution explicitly, because the factory will otherwise default to the adult pattern
2. Not budgeting for testing — 150-500 USD per style per colorway. A brand that prices a kidswear line without this line item loses money on every unit
3. Not realizing you are the importer of record — you hold the CPC and take the legal responsibility, not the factory
4. Small parts on garments for under 3s — buttons, bells, and beads on that age group must pass a small-parts test. Avoid them entirely in the first range
5. Labeling by age only — a “5 year old” label spans 11 cm of height. Label by height in cm and publish the chart
6. Neglecting the safety margin in the design — growing children need room. Under-designed growth room means the garment is outgrown in a month, which is a refund
7. Testing only the fabric — trims, threads, inks, and prints all carry the same restricted-substance burden
8. Splitting the run too thin across too many sizes — 500 pieces across 8 sizes is 60 per size, and the sizes that sell will run out while the slow ones sit. Start with 4-5 core sizes

Quality checks specific to kidswear

Add these to the inspection brief:

• No cords in the neck or back hood area, and no exposed cords anywhere. Check every garment, not a sample of them
• No small parts: check that buttons and snaps are secure and correctly sized for the age label
• Label presence: fiber content, country of origin, care instructions, and the age range on every garment
• Stitching: check the seams that take the most abuse, crotch seams, sleeve seams, and the rib attachment
• Rib recovery: stretch the cuff 20% and release
• Colorfastness: spot-check a wet-white-cloth rub on a hidden seam area
• Print and embroidery: no cracking, no sharp edges, no loose threads a child could pull at
• Fit against the size chart: measure a sample from each size, not just the middle size

How to structure the inspection request is covered in our QC and AQL guide.

Packaging for kidswear

• Flat fold, folded in thirds. Small garments can be folded smaller; specify the fold so the cartons stay uniform
• Individual poly bags, 0.04-0.05 mm, perforated
• Use a size sticker on the bag, not just the garment label, so the warehouse can pick correctly
• Typical unit load: 50-80 pieces per master carton
• A 20ft container holds roughly 25,000-35,000 kidswear tops; a 40ft high cube holds 60,000-80,000

Carton and container math is in our packaging and container optimization guide.

FAQ

What certificates do I need to sell kidswear?

For the US: third-party testing for lead and phthalates, then a Children’s Product Certificate per style, issued by the importer of record. For the EU: technical documentation, a responsible person in the EU, and traceability under GPSR, plus REACH compliance for restricted substances. Most buyers will ask for both if you are selling cross-border. Budget 150-500 USD per style per colorway for testing.

Are drawstrings completely banned on children’s clothing?

Not completely, but heavily restricted. EN 14682 prohibits cords in the neck and back hood area on garments for children under 7 years, prohibits cords that form a loop in that area, and limits cord length elsewhere. The practical answer for a new brand: use an elastic casing with no exposed cord for anything under 7 years. It is simpler, safer, and it removes the question entirely.

How do I size kidswear so parents stop returning it?

Label by height in centimeters and publish a chart with actual garment measurements. Include the equivalent age range as guidance, not as the sizing system. Build in growth room, especially in body length and hem, and state the growth allowance on your product page. And publish actual garment measurements, not just the size label, because parents compare across brands.

Do I need a different MOQ per size?

No. The MOQ applies per style per color, and the factory cuts all sizes from the same dye lot. A 500-piece order across 8 sizes is 500 pieces total. This is what makes kidswear size runs practical. But check the minimum per size with the factory: some require 20-30 pieces per size so that no size is so thin it is unworkable, and some need 50.

What is the cheapest way to start a kidswear line?

One age group, four sizes, one color, one style, with the simplest compliant construction: a crewneck or a short-sleeve tee with a print, an elastic-waist bottom, and no cords anywhere. Budget around 300-400 USD for testing on top of the order, and 500-800 pieces total for a workable first run.

How much should custom kidswear cost?

FOB from China, a 500-piece run of a 5/6-year-old fleece hoodie with a print and compliant construction: about 7-9 USD per piece, plus 0.60-1.00 USD of testing amortized across the run. A cotton tee program lands around 4-6 USD plus testing. DDP into the US typically lands 20-35% above the FOB price. For the general cost model, see our pricing guide.

Can I reuse the same garment for boys and girls?

Yes, and it is usually the right move for a first range. Unisex cuts are simpler to produce, halve your size run, and the color and graphic carry the positioning. If you do separate them, expect to manage twice the SKU count and twice the testing cost, for very little additional revenue.

Does compliance cost change if I only sell to one country?

It reduces it, but only partly. Testing for lead and phthalates is the foundation and it satisfies most requirements. The EU adds the responsible-person and technical-documentation requirement, which is administrative rather than a lab cost. If you are starting, testing for the US standard plus a small documentation budget is the most transferable base.

What about swimwear and sleepwear?

Both carry extra requirements. Swimwear needs chlorinated-water colorfastness testing, and sleepwear for children under 1 must meet the flammability standard (16 CFR 1610 in the US). Both are doable but they need their own testing budget, so they are not good candidates for a first range.

How this fits the buyer journey

Everything in the general cluster applies. These are the ones that matter most for kidswear:

• Contracts and IP Protection — who holds the CPC and the compliance obligations
• Custom Fabric Development — GSM, blends, shrinkage and growth room
• Sizing and Grading — height-based sizing and kidswear grade rules
• Decoration Methods — print and thread compliance
• Trims and Labels — small parts, labeling requirements
• Custom Apparel Pricing — including the testing cost line
• MOQ Guide — why the MOQ is per color, not per size
• Lead Times — kidswear timelines
• QC and AQL — the kidswear-specific inspection checks
• Packaging — fold method, size stickers, container loading
• Activewear — performance fabrics for older age groups
• Hoodies and Sweatshirts — hoodie construction and cord rules
• How to Start a Clothing Brand — first-run planning

How we work at Kemondo

At Kemondo Apparel, we build kidswear to the compliance requirement from the first sample, not after a customs hold. Every kidswear tech pack we issue states the drawstring construction explicitly, the small-parts policy for the age range, the label set required, and the testing scope, so the factory cannot default to an adult pattern with a hood cord. We work with three accredited testing laboratories and can arrange testing against the same sample that goes to bulk, so the test report reflects the production fabric rather than a proxy. Our kidswear patterns are developed on height-based grading with growth room built into the body length and hem, and our size runs are quoted per age group with the minimum per size confirmed with the factory. For MOQ, we hold 240-320 gsm cotton fleece and cotton jersey in 10 standard colors so a compliant 500-800 piece first run does not have to wait on a mill. And we are straightforward about the two things that catch new buyers out: the testing cost needs to be in the unit economics from the start, and the importer of record is the buyer, which means the compliance responsibility is yours, not ours.
