For North American buyers

Your next best factory isn’t in China.

Verified Colombian factories. Vetted in person. Four hours from Miami.

We walked Medellín factories in August 2026 and scored each against our published standard. Four are published now, each carrying what we saw on the floor and what we were only told. Tell us what you need made and we take it to the ones that fit.

Send the tech pack you already have. WestOS turns it into a specification a factory can price.

Why now

01 · The China era

Why China won textiles.

For thirty years the math was unbeatable: unmatched scale, a complete ecosystem — fiber to finished garment in one region — and prices nobody could touch. By 2010, roughly half of all US apparel imports came from China.

Durante treinta años las cuentas eran imbatibles: escala inigualable, un ecosistema completo — de la fibra a la prenda terminada en una sola región — y precios intocables. Para 2010, cerca de la mitad de todas las importaciones de ropa de EE.UU. venían de China.

02 · What changed

The math stopped working.

Layered duties on Chinese apparel now commonly run 30–50%+ combined. The ocean adds 13–18 days port-to-port — 30–45 door-to-door. Freight whiplash is routine: Shanghai→LA spot rates jumped 12% in one week this June. China’s share of US apparel imports has fallen to about a third.

Los aranceles acumulados sobre la ropa china hoy suelen llegar a 30–50%+ combinados. El océano añade 13–18 días de puerto a puerto — 30–45 puerta a puerta. Los fletes dan latigazos: las tarifas spot Shanghái→LA saltaron 12% en una semana este junio. La participación de China en las importaciones de ropa de EE.UU. cayó a cerca de un tercio.

03 · The nearshore answer

The Americas are open.

Medellín is a ~3.5-hour flight from Miami; sea freight from Colombia lands in about 3 days, not weeks. Under the US–Colombia TPA, qualifying apparel enters duty-free — and starting 2026, quotas are gone. The cluster is real: Colombiamoda 2025 drew 650 brands and 11,000 buyers. 79% of sourcing executives plan to move at least 20% of volume out of China within 24 months.

Medellín está a un vuelo de ~3,5 horas de Miami; la carga marítima desde Colombia llega en unos 3 días, no semanas. Bajo el TLC EE.UU.–Colombia, la ropa calificada entra libre de aranceles — y desde 2026, sin cuotas. El clúster es real: Colombiamoda 2025 reunió 650 marcas y 11.000 compradores. El 79% de los ejecutivos de abastecimiento planea sacar al menos 20% de su volumen de China en 24 meses.

04 · The missing layer

What’s been missing is trust. That’s WestOS.

We run a standardized, in-person factory check. We’re walking Medellín factories ourselves in July 2026. A curated network: verified Colombian factories on one side, vetted North American buyers on the other. Every deal teaches WestOS how to make the next one smoother.

Realizamos una verificación de fábrica estandarizada y en persona. Nosotros mismos recorreremos fábricas de Medellín en julio de 2026. Una red seleccionada: fábricas colombianas verificadas de un lado, compradores norteamericanos examinados del otro. Cada negocio le enseña a WestOS cómo hacer el siguiente más fluido.

The standard

What we check before a factory makes the list.

Seven stations on every walk — the same published rubric for every factory, scored in person against written anchors. Your pre-RFQ diligence, done on foot.

Floor & flow

Machines & maintenance

Sample room & development

Capacity & planning

People & culture signals

Compliance & export readiness

The complete Factory Walk Sheet is public: every item, every point.

The rules

Same rules for everyone.

Introductions made through WestOS stay in WestOS. We see every deal through, start to finish. That is what keeps the record true, and the record is what protects you. Circumvention ends access, permanently.

Questions buyers ask

Sourcing from Colombia: the practical questions.

What is the minimum order quantity at Colombian apparel factories?

It varies widely by factory. A small sewing workshop and a full-package plant quote very different minimums, and the same factory will often flex its MOQ for a serious buyer with clean tech packs. WestOS records each factory’s real minimum on its scoresheet during the walk, so we know before you do whether a floor can take your volume.

Tell us your monthly volume in the form below and we filter for it before you ever talk to a factory.

Is apparel from Colombia duty-free into the United States?

Often, but not automatically. Under the US–Colombia Trade Promotion Agreement, garments enter duty-free only if they qualify under the yarn-forward rule of origin: in general, the yarn and fabric must be made in the United States or Colombia. Cut-and-sew programs using Asian fabric usually do not qualify.

Since 2026 the remaining quotas are gone. We record where each factory sources its fabric on the walk, so you know before the RFQ whether your program can qualify.

How long does shipping from Colombia to the US take?

Days, not weeks. Medellín is a ~3.5-hour flight from Miami for samples and small air shipments, and sea freight from Colombia lands in about 3 days. Compare that to the 13–18 days a container spends crossing the Pacific, before port congestion.

Shorter transit means smaller buffers, faster reorders, and less cash locked up on the water.

How does WestOS vet a factory?

In person. We walk every floor ourselves for 60–90 minutes and score it item by item against the published WestOS Standard: seven stations covering floor and flow, machines, quality, sample room, capacity, people, and export readiness. Certifications are verified at the source, not photocopied.

Buyers see proof ranges and verified claims, never a factory’s raw numbers. The full standard is published on the factories page.

What does this cost the buyer?

Nothing. There is no access fee and no subscription. Tell us what you need made and the volume you need, and we take it to the factories we have walked and come back with what they will commit to.

We work at cost on turn one. Mostly, we eat the plane tickets.

Do I need to speak Spanish to work with a Colombian factory?

No. WestOS bridges English and Spanish in the same WhatsApp thread. We stay in the conversation through your first order, so nothing is lost between your tech pack and the production floor.

Export experience, including English documentation, is one of the seven stations we score. You’ll know a factory’s level before the first call.

What if one factory can’t handle my volume?

Most Colombian factories are small. That’s normal here, and it’s why the standard matters. Because every factory on the list is scored against the same published rubric, WestOS can coordinate several verified factories to produce a large order together, instead of you betting everything on a single floor.

That’s the road we’re building toward. Ask us about volume splitting when you send your requirements.

What do you want to make?

Send whatever you already have. We turn it into a specification a factory can price, and take it to the floors we have walked.

Drop your tech pack, a current quote, reference photos Anything you already have. Several files are fine.

Your files are private to WestOS. We use them to write a specification, and we agree it with you before anyone else sees it. Factories receive only that specification. They do not receive your original files, your name, or your company identity, unless you tell us otherwise.

A floor prices from six answers

The garment A photo or a reference product is enough.
The fabric Composition, weight, who supplies it.
Operations Print, embroidery, wash, trims.

Your files likely cover the first three. Whatever is missing, we ask once, by email. Never a form.
