Swimwear Manufacturer in China: Bikini, Custom Sets & Low MOQ Guide (2026)

August 24, 20269 min readBy Essty Garment

Swimwear sells on a tight seasonal calendar but repeats hard — bikinis, one-pieces, tankinis, and matching cover-up sets move fast across Africa, the Middle East, and resort markets worldwide. If you want your own branded swim line, China remains the default production base for it: fabric markets, knitting and printing workshops, and trim suppliers sit close together in the Pearl River Delta, which keeps both unit cost and lead time down. The catch is that swimwear is unforgiving on fit and fabric — a sheer lining or a fading print kills a brand faster than almost any other category. This guide covers what actually matters when sourcing custom swimwear from China.

Why Source Swimwear from China

Guangzhou and the surrounding cluster put performance-knit mills, sublimation printers, and hardware (rings, sliders, clasps) suppliers within a short radius. That density means a 100-piece swim run is completely normal at a small-batch factory — you do not need a full container to test a bikini or a matching set on TikTok or Instagram. See our fabric selection guide for how material choice drives both cost and wear performance.

What "Custom Swimwear" Actually Includes

Before you request a quote, get specific about the build. Each choice changes fabric cost and production steps:

Silhouette — bikini (triangle, bandeau, high-waist), one-piece (plunge, sporty, ruched), tankini, or a swim set with cover-up.
Fabric — polyester-spandex (printable, chlorine-resistant), nylon-spandex (soft, compressive), recycled poly (RPET/ECONYL-type), or rib knit; weight 180–240 gsm.
Finish — full lining, removable padded cups, adjustable straps, metal or plastic hardware, ruching, or cut-out detail.
Decoration — all-over sublimation print, heat-transfer logo, embroidery, crochet panel, or tie-dye.
Branding — woven neck label, size tag, hangtag, polybag, and custom tissue or sticker.

MOQ: What's Realistic

At a small-batch manufacturer like Essty, the standard is 100 pcs per style (colours can be mixed within reason). That is low enough to test a bikini or set on social without a warehouse, yet high enough for the factory to price fabric efficiently. See our MOQ explainer for the cost math behind the 100-piece floor.

Fabric & Finish Options (with Trade-offs)

Supplier Type	Typical Swimwear MOQ	Best For
Mass-production knit factory	500–2,000 pcs/style	Big reorders, chains
Mid-size factory	200–500 pcs/style	Growing swim brands
Small-batch factory	100 pcs/style	Startups, test drops, influencers
Print-on-demand	1 pc	Prototype, ultra-niche

Option	Look / Feel	Best Use	Note
Polyester-spandex 200 gsm	Smooth, printable, chlorine-resistant	All-over prints, resort sets	Most popular default
Nylon-spandex	Soft, second-skin, premium	High-waist bikini, luxe one-piece	Higher perceived value
Recycled RPET	Matte, eco story, soft	Sustainable lines	Strong marketing angle
Rib knit	Textured, stretchy, sporty	Bandeu, crop tops	Adds a knit step
Scuba / bonded	Structured, sculpted	One-piece with support	Specialised machine

Tip: Always specify full lining and, if selling to pools, a chlorine-resistant finish. Unlined or cheaply lined swimwear is the #1 return reason in this category. Use in-stock solid colours (black, navy, emerald) for your base run and reserve custom dye for your hero prints — custom piece-dyeing often carries its own minimum (300–500 kg of yarn) that defeats a 100-piece test.

Private Label Steps (End to End)

Brief the factory — send a tech pack or clear photos: silhouette, fabric weight, colour, sizing, padding and lining spec, decoration placement. Our tech-pack guide shows the minimum a factory needs.
Get a quote & confirm FOB price — tiered by quantity (100 / 300 / 500 / 1,000+). Confirm what's included: labels, polybag, hangtag, and whether DDP shipping is an option.
Sampling — order 1–3 pre-production samples to check fit, opacity (stretch test over a dark surface), and print quality. The sampling process guide explains the rounds.
Confirm & deposit — production usually starts after a 30% deposit; balance on completion.
Production & QC — 10–15 days for a small batch; inline and final inspection per our QC checklist (lining continuity, strap strength, print registration, and colour fastness checks for swimwear).
Ship — express (DHL/FedEx) for a test run, or sea freight for reorders. See shipping by destination.

What It Costs (FOB, Indicative)

FOB factory price for a basic custom bikini set (polyester-spandex, heat-transfer logo, full lining, woven label) typically lands in a tiered band. Exact numbers depend on fabric weight, padding/hardware, and order size:

Order Size	Relative Unit Cost	Why
100 pcs	Medium	Setup absorbed, in-stock fabric
300 pcs	Lower	Better fabric & label pricing
500 pcs	Lower still	Efficient line, bulk trims
1,000+ pcs	Lowest	Optimised cutting & decoration

Always ask for the price inclusive of your branding (labels, polybag, hangtag) so there are no surprises at checkout. Our cost-breakdown guide walks through every line item, including the lining and hardware that swimwear needs but dresses do not.

Red flags: "No MOQ, factory price" swimwear sellers are almost always resellers marking up stock. Refusing to state MOQ or lead time in writing, or quoting far below market with no explanation, usually means hidden fees or drop-shipped goods. For the EU especially, buyers often ask for OEKO-TEX® on the fabric — confirm with your factory whether their supply chain holds it rather than assuming. Verify the supplier with our factory audit checklist.

Lead Time & Reorders

A 100–300 piece swimwear run runs about 10–15 days after sample approval, plus transit. Because swimwear is seasonal, plan reorders early: a confirmed second run lets the factory buy fabric ahead and shorten your next lead time. Plan seasons with our production calendar so you're not sampling summer prints in October. For sizing across body types, our plus-size guide covers graded curves that matter for high-waist and one-piece styles.

FAQ

Can I mix colours within a 100-piece MOQ?

Yes, at most small-batch factories — e.g., 40 black + 30 navy + 30 emerald still counts as one 100-piece style. Confirm the colour-split rule before quoting, since some factories set a per-colour minimum or charge for extra print plates.

Sublimation print or heat-transfer for my logo?

Sublimation suits all-over prints and resort patterns but needs polyester or recycled poly fabric; heat-transfer and embroidery work on any base and are ideal for small chest or waistband logos. Many brands do both — printed body, transfer logo.

Do I need my own design file?

A clear reference photo plus measurements is enough to start. A full tech pack speeds sampling and reduces revision rounds — see our tech-pack guide.

How do I protect my design?

Use a written agreement and confirm pattern/design ownership up front. Our IP protection guide covers NDAs and who owns the blocks.

Bottom Line

Custom swimwear from China is accessible at 100 pieces if you pick a small-batch factory, specify full lining and chlorine-resistant fabric, and confirm padding and print clearly. Avoid no-MOQ resellers, confirm branding is in the price, and plan reorders by season. Get the lining and fit right and swimwear becomes your highest-repeat category; get them wrong and it becomes your highest-return one.
