Spain & Latin America Underwear Supplier — OEM Manufacturing from China

Based in Xiamen, Fujian Province and working with partner factories in the Xiamen–Quanzhou–Jinjiang knitwear cluster of south-east China, Unitex Underwear is a China-based OEM & ODM underwear supplier serving Spanish and Latin American retailers, department stores, and e-commerce brands. OEKO-TEX materials and BSCI-audited partner factories — we deliver quality, compliance, and competitive pricing for the Spanish and Latin American market.

Why Spanish and Latin American Brands Choose Unitex

• The compliance trail starts before the shipment does. Your importer receives the material and factory compliance file ahead of the container rather than after it clears, so clearing is never held up waiting for a document that was packed with the goods.
• One supplier across the whole route. Design, fabric sourcing, sampling, bulk production and shipping sit inside a single order, so you are not separately coordinating a designer, a mill and a garment factory.
• Paperwork in your language. Order confirmations, packing lists and export documents can be issued in Spanish, which is what most customs brokers in the region ask for first.
• A minimum that fits a mid-sized retailer. 2,000 pcs per style and colour lets you build a colour range without committing to container-scale volumes on a first order.
• Inspection before shipment, not after arrival. Every batch is checked by a dedicated QC team before it leaves, and inspection also runs inline during bulk production rather than only at final packing.

“Latin America” Is Not One Market

Spanish is the language, not the market. A buyer in Madrid and a buyer in Santiago are working to different import rules, different labelling expectations and different tariff positions, and the same container split across three countries can require three different label sets before it can clear anywhere.

Spain sits inside the European Union, so a Spanish order is governed by EU requirements. Latin America is roughly twenty separate countries, each with its own import regime, its own labelling language and its own duty structure. Brazil adds its own certification paperwork on top of that, and Mexico and Chile do not behave like each other either.

The practical consequence is that a regional roll-out works better as separate purchase orders per country than as one order split at the end. Labels, cartons and documents can then be built for a single destination, and a customs problem in one country does not hold up stock destined for another.

If you are buying for several markets at once, tell us which ones at the enquiry stage. It changes the labelling plan, and it is far cheaper to build that in than to re-label after the goods have been packed.

Sizing Across the Region

Spain sizes to the European system, which is a stable and well-documented reference. Latin America does not use one system: some markets follow European numbers, others have drifted close to US sizing, and Brazil maintains its own scale that does not translate directly from either.

The failure mode is predictable. A size chart that works for a Spanish retailer can produce a programme that does not fit in Brazil or in parts of the Andean market, and the error only surfaces after the goods are on a shelf.

For a first order we work from a size chart or a reference sample rather than from size numbers alone. Send the size set you sell with the measurements behind it, and we will confirm the grading before the pre-production sample is made, when a correction is still cheap.

The Buying Calendar Runs Two Ways

Most of the region buys on a northern-hemisphere calendar: Mexico, Colombia and Central America follow the same spring and autumn rhythm as Europe and the United States. The southern cone does not. Chile, Argentina, Uruguay and Paraguay run the opposite season, so their spring and summer buying window lands in what the northern hemisphere books as autumn and winter.

That matters for production planning, because the Chinese New Year shutdown falls in January or February, right before the southern-hemisphere selling season is filled. A southern-cone summer order placed in the northern spring competes for factory capacity with the northern autumn programmes, and the two are not equally movable.

The working rule: southern-cone buyers should place summer programmes with more lead time than a European buyer would use for the same delivery window. If your sell season starts in December, the production slot needs to be booked in the third quarter rather than alongside the European autumn bookings.

Compliance and Labelling

Compliance paperwork is not one document. It splits into the material side, which travels with the fabric, and the destination side, which belongs to the country the goods are entering.

On the material side, our partner factories work to OEKO-TEX-compliant materials and hold BSCI social-compliance audits, and the material documentation can be issued with the shipment so your importer has it on file before the goods arrive. For Spanish orders, this sits inside the EU framework the buyer already works to.

On the destination side, requirements differ by country and sometimes by product category. Fibre-composition and care labelling, importer identification and language requirements are the usual variables, and Brazil layers its own certification paperwork over the top.

We support this with documentation rather than advice: tell us the destination country and the product category, and we will tell you which documents we can provide and which ones your importer needs to arrange locally. Certifications covering a specific order are arranged against that order, not assumed.

What to Send With Your First Enquiry

A first enquiry moves fastest when it carries six things:

1. The style, or a reference sample if the style is not finalised
2. The destination markets, listed per country rather than as a region
3. The size set you sell, with the measurements behind it
4. Your target FOB price band, so the fabric and trims can be proposed to match
5. Quantity per colour and total quantity, since the colour split drives both the MOQ and the loss rate
6. Packaging and labelling requirements, including retail-ready or plain export packing

Nothing here needs to be final. A brief that is roughly right on all six moves to a quotation faster than one that is exact on two and silent on the rest.

Product Categories

The range is knitted underwear for men, women and children, plus pajamas and sleepwear, and every category is open to your own branding, packaging and specification.

For Spanish-speaking markets the steady sellers are cotton and cotton-blend men’s basics, women’s briefs and bikinis, and children’s sets. Fabrics can be developed against the hand-feel and the price point you are working to, and the size set is built around the market you are selling into rather than a single regional default.

How to Start Your OEM Order

1. Send a design brief or a reference sample — the review comes back within 48 hours
2. Fabric swatches and a quotation follow in 3-5 business days
3. The pre-production sample is approved on a 5-7 day cycle
4. Bulk production runs 45-60 days with inline QC inspection
5. Shipping is quoted FOB Xiamen or CIF to your port

For a programme where the goods will be split across more than one country, say so at this stage — it changes the packing and labelling plan, and it is easier to build in than to correct later.
