Top Swimwear Manufacturers in Vietnam: Verified Factory List and Sourcing Guide
Swimwear is one of the harder knit-apparel categories to manufacture, and Vietnam's actual swim production base is much smaller than directory listings suggest. Swim fabric has to hold stretch and recovery through repeated wear, resist chlorine and saltwater, retain color under UV exposure, and bond at the seams without rolling. Most knit factories in Vietnam build t-shirts and leggings without those constraints. The factories that handle all of them are a different and shorter list.
Most brands looking for swim factories in Vietnam end up at directory names that quote swim opportunistically and produce it poorly. The real swim base is more layered than the lists show: Korean-linked specialists in technical knit, mid-volume factories running ladies' bikinis at 800-piece MOQs, multi-vertical apparel groups that ship swimwear alongside intimates, and a long tail of small bespoke producers that never make any directory. I work across all of these tiers.
I source swim from Vietnam through Cosmo Sourcing's Binh Duong office, which has been running since 2014. Most of the brands I work with arrive after months of dead ends with directory introductions or commission-based agents who would not break out their fees. The factory list below is built from real shipping records and factory-floor vetting, not directory mining.
Why Vietnam for Swimwear
Vietnam works for swim for two reasons: construction overlaps with activewear, so existing factories already know how to build it, and trade-agreement coverage gives non-US buyers a real duty advantage.
Cross-category factories under one roof
Several Vietnamese factories ship swimwear alongside other knit-apparel categories, which means a brand sourcing both swim and activewear can consolidate under one supplier. The factories that produce technical activewear, pickleball sportswear, and T-shirts often run swim in smaller volumes too, and several swim specialists on the list below ship rashguards, swim shorts, and base-layer knits.
Trade-agreement coverage and sustainability positioning
Vietnam holds free trade agreements with the EU (EVFTA), the UK (UKVFTA), Canada, Japan, and Australia (through CPTPP and RCEP). Duty preferences on knit apparel codes are meaningful for brands shipping to those markets, and EU buyers increasingly require Global Recycled Standard (GRS) certification for recycled-content claims, which several Vietnamese swim factories now hold. The US has no FTA with Vietnam, so US importers pay the standard MFN rate plus any current additional US duties on the relevant codes; confirm landed cost with a customs broker before placing large orders.
Top Verified Swimwear Factories in Vietnam
Each factory below has enough swim shipping volume to be a real swim producer, not a generalist apparel maker quoting swim opportunistically. Freight forwarders and logistics intermediaries are filtered out.
Fook Wah Kun Kee Knitting Factory
The highest-volume swim shipper in the dataset, shipping knitted swimsuits and knitted swim trunks. The Fook Wah name appears across multiple corporate entities; this top entry ships from Vietnamese ports (Hai Phong, Vung Tau), while smaller Fook Wah-named entities ship from Hong Kong, Nansha, and other Chinese ports. I'd send a brand here that's placing 1,500+ pieces per style on a swim-specialized line, ideally a women's-led range with steady reorders. Smaller launches won't be a priority here, and sample turn can drag during peak production windows.
King Hamm Industrial
Tied for the top swim shipping volume. Heavy on women's swimsuits, including private-label work for established US swim brands. Southern Vietnam departures (HCMC, Vung Tau). This is where I'd send a brand that's outgrown a smaller HCMC studio and is moving up to consistent multi-thousand-unit runs. King Hamm is less visible online than directory-listed factories, which is normal at this tier of producer; vetting happens through direct introduction rather than web research.
Seyang Corp Vietnam
My first call for kids' and family swim. Heavy on polyester-elastane knit swimsuits, kids' and infant rashguards, swim shorts, and rashguard tops, which is narrower than generalist swim. Departures span Yantian and Hai Phong, indicating a cross-border production or transshipment pattern rather than pure Vietnam-port exports. The transshipment pattern adds lead time compared to a pure Vietnam-port shipper, and brands with strict made-in-Vietnam labeling requirements should confirm origin documentation before placing orders.
Seshin Vietnam
For brands that want Korean technical knit expertise at Vietnam labor costs. Ships girls' knit bikinis, one-pieces, and ladies' knit swimwear, with departure ports including Pusan, Kwangyang, and Kaohsiung, indicating a Korean or Korean-Taiwanese supply chain connection in addition to Vietnamese production. Deeper specialty-knit expertise typically comes with less price flexibility on small orders, and project communication may run on Korea Standard Time depending on which office handles the account.
Tien Hung Joint Stock Company
A solid mid-tier match for emerging-to-mid brands placing 800 to 2,000-piece orders on standard knit construction. Ladies' knit swimwear is the primary product; Hai Phong departures; consistent volume across the past year. Tien Hung has less depth in specialty linings (PBT, performance compression) and printed swimwear than the top-volume names, so verify with sample requests whether the brand needs technical fabric construction.
FWKK Vietnam
FWKK shares the Fook Wah Kun Kee name and likely shares ownership or operational ties with the higher-volume Fook Wah entry above, though the corporate relationship isn't fully verifiable. Ships girls' synthetic-fiber knit swimsuits and women's swim separates. Useful as backup capacity within the parent group rather than as a fully independent second source. If you need diversified supplier risk, pair FWKK with a factory of different ownership on this list rather than treating Fook Wah and FWKK as two unrelated suppliers.
Minh Anh Kim Lien Garment JSC
The match for brands running mixed knit and woven swim under one roof: classic cut bikinis paired with woven board shorts or cover-ups. Produces both ladies' nylon-spandex knit swimsuits AND polyester-woven swimsuits, which is unusual since most swim factories specialize in one or the other. Hai Phong and Vung Tau departures. Cross-category versatility comes at the cost of swim specialization depth, so prioritize Minh Anh when the range genuinely spans knit and woven, not as a pure premium swim choice.
Yat Fung International Development
The pure swim specialist on this list. Ships swimwear only, no adjacent product categories, so swim production won't be deprioritized for higher-margin work. Lower volume than the top names, departures from Yantian and Shekou. The departure pattern indicates substantial transshipment through southern China; expect a few extra days of lead time and confirm the actual cut-and-sew location before any country-of-origin claim.
Types of Swimwear Vietnamese Factories Produce
Women's bikinis and one-pieces
The largest category, handled by every factory on the list above. Recycled-content variants (REPREVE polyester, ECONYL nylon) are widely available, and digital fabric printing is mature.
Men's swim
Common but less specialized than women's. Look for factories that explicitly produce men's swim, since some women's-focused factories outsource men's runs rather than build them in-house.
UPF rashguards
Rashguards sit at the swim-activewear intersection. Most technical-activewear factories produce them well, and several of the swim specialists on the list above ship rashguards alongside their core swim book.
Kids' and family swim
A growing sub-segment. Seyang Corp Vietnam is the strongest kids' shipper on the list, and Itas Mars Intimates Fashion ships kids' swimwear under US private-label arrangements (including Target's Cat Jack).
Performance and competitive swim
A narrower set of factories with bonded-seam capability and drag-reduction fabric experience. Cross-reference factories that also produce technical activewear, since the construction overlap is high.
Neoprene and wetsuit construction
Surf-spec and wetsuit-grade construction shifts to specialized neoprene factories outside this list. None of the eight factories above are the right call for neoprene work.
Fabrics, Construction, and the QC Failure Modes I See Most
Fabrics and construction
Four core fabric platforms run the Vietnamese swim market: nylon-spandex (Lycra) for premium feel and stretch, polyester-spandex for chlorine resistance and cost, recycled polyester (REPREVE-class) for sustainability positioning, and regenerated nylon (ECONYL-class) for premium recycled content. Specialty PBT (polybutylene terephthalate) linings carry shape retention and chlorine resistance for performance and competition swimming. Most factories source core fabric from Korea, Japan, Taiwan, or specialty mills in China and finish in-country.
Construction is fairly standardized: four-needle flatlock seams as the baseline, bonded edges (heat tape or ultrasonic) on premium lines, elastic insertion by binding (lower cost) or an insertion machine (premium finish), and lining in single-layer power mesh, a fully lined nylon-spandex shell, or PBT-class technical lining for performance.
The four checks that separate a competent swim factory from a marginal one
Seam-strength on stretched samples, colorfastness on chlorine and saltwater, four-way stretch recovery, and inline QC on bond integrity. Skipping any of these is where most first-order swim brands lose money.
Common quality issues
The single most common failure on first orders is colorfastness on chlorine and saltwater exposure, especially with budget polyester-spandex blends and printed patterns. Always require a chlorine-soak test result before bulk production, not just a wash test. The second most common failure is seam roll on bonded edges when the factory has substituted heat tape for proper ultrasonic bonding.
Certifications worth asking about
OEKO-TEX Standard 100 for fabric chemical safety (widely held). Global Recycled Standard (GRS) for recycled-content claims on REPREVE and ECONYL platforms. BSCI or Sedex for social compliance is important for retailers with public ESG commitments. For US-market kids' swimwear, factories should provide CPSIA-compliant testing by an accredited third-party lab.
MOQs, Lead Times, Payment, and Shipping
Minimum order quantities
Most established Vietnamese swim factories quote MOQs of 300 to 1,000 pieces per style, per color, per size run. Smaller bespoke studios in Ho Chi Minh City accept orders as low as 100 to 500 pieces, but those won't appear on the list above. Larger export factories targeting mid-to-large brands start at 1,500 to 3,000 pieces per style. The factory you pick should match your launch volume, not your aspirational year-three volume.
Lead times
A typical first-order cycle from tech pack to shipment runs 90 to 120 days: 14 to 21 days for fabric sampling, 14 to 21 days for fit and pre-production samples, 60 to 75 days for bulk production, then 7 to 14 days for finishing, packing, and inspection. Repeat orders on existing patterns shorten to 60 to 75 days.
Seasonality and capacity
Most US and EU swim brands order for May to July retail drops, which puts sampling and bulk runs in the November to March window. That's when capacity tightens at the larger Vietnamese swim factories. For peak-window orders, book sample slots 3 to 4 months earlier than the math suggests.
Payment terms
Standard payment terms with Vietnamese swim factories are 30 percent deposit on order confirmation and 70 percent against shipment documents, either before sailing or against a copy of the bill of lading. First-order brands sometimes face 40 percent deposit terms until trust builds. Bank wire (TT) is the default; letters of credit are available for large orders, but add cost and time.
Shipping transit times
Typical sea freight transit times from Vietnam's main ports are 14 to 18 days from Ho Chi Minh City or Hai Phong to Sydney or Melbourne, 14 to 18 days to the US West Coast, 25 to 30 days to the US East Coast, and 28 to 32 days to Northern European ports (Rotterdam or Hamburg). Add 5 to 10 days to each end for inland transit and customs clearance.
Vietnam vs China vs Indonesia for Swimwear
The three Southeast Asian options for swim production are Vietnam, China, and Indonesia (often referred to by shorthand as Bali, where the design-led, small-batch swim ecosystem is concentrated). Each is best for a different brand profile.
| Factor | Vietnam | China | Indonesia (Bali) |
|---|---|---|---|
| Best for | Mid-volume brands, dual swim and activewear, EU and CPTPP duty preferences | High-volume orders, deepest fabric library, fastest tooling | Low-MOQ launches, ethical and small-batch positioning |
| Typical MOQ floor | 300 to 1,000 per style | 1,000 to 3,000 per style | 50 to 300 per style |
| First-order lead time | 90 to 120 days | 75 to 100 days | 90 to 150 days |
| Recycled fabric availability | Strong and growing (REPREVE, ECONYL widely available) | Strong | Varies, often higher-cost |
| CSR audits available | BSCI, Sedex, GRS available | Available, reputation varies | Strongest informal positioning, weaker formal certs |
| EU duty advantage | EVFTA preferences | Standard MFN | GSP tier, partial preferences |
Where I route brands: Vietnam for any brand placing 500 to 5,000 pieces per style and shipping to multiple markets, especially to the EU, UK, Canada, Japan, or Australia, where FTA preferences pay off. China only when volume is north of 10,000 pieces per style and the brand is shipping non-US, since the tariff drag on US imports usually erases the cost advantage. Indonesia (Bali) for ethically sourced, small-batch launches of 100 to 300 pieces per style.
Frequently Asked Questions
Is Vietnam a good country to manufacture swimwear?
Vietnam is one of the strongest swim manufacturing countries in Asia, with mature stretch-knit fabric capability, growing recycled-content infrastructure, and competitive cost positioning between China and Indonesia. The country's free trade agreements with the EU, the UK, Canada, Japan, and Australia provide additional duty advantages for non-US markets.
What is the minimum order quantity for swimwear in Vietnam?
MOQs in Vietnam typically range from 300 to 1,000 pieces per style, per color, per size run for established export factories. Smaller bespoke studios in Ho Chi Minh City accept orders as low as 100 to 500 pieces. Larger factories targeting high-volume contracts start at 1,500 to 3,000 pieces per style.
Which fabrics do Vietnamese swimwear factories use?
The four core platforms are nylon-spandex (premium stretch and recovery), polyester-spandex (chlorine resistance, cost), recycled polyester (sustainability positioning), and regenerated nylon (premium recycled content). Specialty PBT linings appear on performance and competition lines. Most factories source fabric from Korea, Japan, Taiwan, and China and finish it in Vietnam.
How long does swimwear production take in Vietnam?
A first-order cycle from tech pack to shipment runs 90 to 120 days. Repeat orders on existing patterns shorten to 60 to 75 days. Sample development alone runs 14 to 21 days for fabric sampling and another 14 to 21 days for fit samples.
Can I get private-label or OEM swimwear made in Vietnam?
Yes. Most Vietnamese swim factories support both private label (your brand on a factory pattern) and full OEM (your design from a tech pack). Many also offer ODM services, in which the factory provides design input. The level of design support varies by factory and is one of the questions to ask during the vetting process.
How Cosmo Sourcing Works with Swim Brands
If you've done the directory rounds and been quoted by factories that never made a swimsuit, here's what Cosmo Sourcing does instead.
You send the brief: products, MOQs, fabric, target markets, certifications. My team in Binh Duong cross-references your spec against shipping data and factory visits, then returns quotes from 2 to 6 matching factories: high-volume names when they fit, smaller specialists when they do not. No markup on factory quotes. No commission. Cosmo Sourcing charges a fixed fee per project, so the pricing you see is the factory's actual pricing. After sampling, I introduce you directly to the chosen factory so you own the relationship from day one.
Cosmo Sourcing has worked with thousands of brands across 10,000+ products since 2012, including swim and beachwear clients at its original Vietnam factory for 3+ years.
