Portugal e contexto europeu

Portugal and EU context. The standard IVA (VAT) rate in Portugal is 23% — applies to most merch products and gadgets. Reduced rates are 13% (intermediate, for food, beverages, accommodation) and 6% (reduced, for printed matter like books, notebooks, cultural brochures — this is the relevant rate for printed merch products). Since 2023 the e-Fatura system of Autoridade Tributária e Aduaneira (AT) is mandatory for all B2B transactions — full integration with client financial systems (SAP, Primavera, PHC, Sage, Microsoft Dynamics). Portuguese remains the default language on invoices and labels, with English standard in international documents. CNPD (Comissão Nacional de Proteção de Dados) requires RGPD compliance when collecting employee data for merch programs (names, numbers, size preferences). GOTS, GRS, FSC, OEKO-TEX Standard 100 and EU Ecolabel certificates are honoured across the EU — for products in food contact Regulation (EC) No 1935/2004 also applies. T-shirt, hoodie, cotton bag categories fall under these regulations and we work in full compliance.

Preços e enquadramento

Pricing and financial framework. We quote in EUR with IVA 23% (standard rate) or 6% (reduced rate for printed matter per official list). For enterprise clients we offer framework agreements with volume discount tiers — from 5% at EUR 5,000 annually to 15% at EUR 50,000 annually. Payment by proforma invoice 50% deposit + 50% before dispatch for new clients; for recurring B2B clients payment terms 14-30 days. We accept SEPA bank transfers (EUR), payment cards via Stripe, MB WAY and Multibanco for Portuguese clients, deferred payments for the public sector. Invoices are issued in e-Fatura format since 2023 as mandatory. For T-shirt, hoodie, cotton bag categories the standard price tiers apply — 10-50 EUR net per piece for basic products, 50-200 EUR net for premium gifts.

Prazo de execução

Lead time. Standard cycle for T-shirt, hoodie, cotton bag — 5-8 working days (digital proofing + production + control + delivery). For projects with extensive personalisation (Pantone embroidery, debossing, name-personalised digital print) — 10-15 working days. For Asia imports (production + sea freight + customs clearance at Leixões or Lisboa) — 8-12 weeks. During the autumn season (September-November) and pre-Christmas period (November-December) timelines extend by 1-2 weeks. For recurring B2B clients we maintain a 10% warehouse buffer — we recommend quarterly planning ahead.

Planeamento sazonal

Seasonal planning. Portugal has strong B2B merch seasons — January-February (new year welcome, annual plans), April-May (Easter, Mother’s Day), June (end of school year, summer collection launches), September (back-to-school, trade shows), October-November (conferences, Q4 launches), December (Christmas, Black Friday). Onboarding programs for new employees are most often launched in January and September. For T-shirt, hoodie, cotton bag categories the customer campaign calendar should be synchronised 6-8 weeks ahead to avoid production and delivery delays.

Envio e logística

Shipping and logistics. Central warehouse in Lisboa (industrial zone). Shipping via CTT Expresso (national network, pickup points, economy option), DHL Portugal (domestic and international express up to 70 kg), DPD Portugal (tracking + delivery up to 31.5 kg), UPS Portugal (international express), GLS Portugal (European network), NACEX (urgent Iberian deliveries).

What it is

The T-shirt technique is one of 13 decoration methods offered by Corp-Merch in Portugal — each method has its optimal material, batch and quality range. T-shirt provides durable and aesthetic B2B merch decoration — withstands industrial washing, abrasion and UV exposure without colour or shape loss.

For B2B clients in Portugal we offer T-shirt in variants matched to the brief — Pantone colours, ICC FOGRA39 profiles, AQL 1.0-2.5 control. T-shirt requires digital proofing (PDF/X-1a) and a physical pre-production sample before launching the full run.

Portuguese and European production facilities in the T-shirt technology offer different quality tiers — economy, mid and premium. Each project in T-shirt technology passes AQL inspection — random 5-10% sample of the batch checked visually and dimensionally before packing.

T-shirt is the most frequently ordered product in the T-shirt category — popular in onboarding, event and loyalty programs in Portugal. hoodie in the branded version is a standard element of welcome packs for new employees and enterprise clients in Lisboa.

cotton bag with the client logo works well in seasonal campaigns and ambassador programs — 5-8 week lead time. bandana is available in Pantone-accurate variants, with certificates and premium gift or eco packaging.

polo shirt accompanies Corp-Merch clients from the first brief to delivery, with a dedicated project owner. Selection of cap in the T-shirt category is based on client brief specifications, warehouse availability and campaign calendar.

When to order

Standard lead time for T-shirt is 3-5 working days for proofing + 5-8 days for serial production with AQL control. Seasonal windows should be reserved early — Black Friday and Christmas require 6-8 weeks total.

For T-shirt with multi-colour design (Pantone 4-6 colours) the cycle is 8-12 weeks. Express 24-72 hour turnaround is available for T-shirt from the local Lisboa studio.

The July-August holiday period extends production by 1-2 weeks at partners. For T-shirt with name personalisation production requires the names file — deliver 2 weeks before production date.

T-shirt — summer collection available from March to August, 8 weeks ahead of first delivery. hoodie — autumn collection launched in August-September, delivery October-November.

cotton bag — limited holiday edition, brief in October, delivery first half of December. bandana — warehouse rotation quarterly; minimum reasonable execution time 4-6 weeks for T-shirt.

Specification

Technical specification of T-shirt — Pantone Coated/Uncoated for brand colours, ICC profiles for CMYK, min. 300 dpi for bitmaps. Screens and forms — screen-printing (120-180 mesh for textiles, 200-300 mesh for paper), DTG (Epson 1440 dpi), DTF (75 μm PET films).

Embroidery threads — Madeira Polyneon 40 (polyester, 401 colours), Coats Sylko (metallised gold/silver). Inks — Pantone Aqua screen-printing (water-based, eco-class), Plastisol (durable, intense colour), special (metallic, fluorescent).

Tests and certificates — OEKO-TEX Standard 100 for inks and textiles, GOTS for organic cotton, REACH, EN 71. Quality control — AQL 1.0-2.5, 100% visual inspection for premium details, 5-10% sampling for economy series.

Specification of T-shirt — Pantone Coated/Uncoated for brand colours, min. 300 dpi for bitmaps, AI/EPS/SVG files for logo. Materials of hoodie — OEKO-TEX Standard 100 certificates, optionally GOTS for organic cotton or GRS for recycled polyester.

Common mistakes

Wrong file resolution — 72 dpi bitmaps look sharp on monitor but pixelate in production; minimum 300 dpi at 1:1. Wrong Pantone colours — Pantone Coated for glossy paper, Pantone Uncoated for matte paper.

Missing bleeds — files without 3-5 mm bleeds cause white edges in production. Too small elements — text below 6 pt is unreadable in screen-printing, lines thinner than 0.3 mm disappear in DTF.

Wrong colour encoding in PDF — RGB instead of CMYK causes colour shifts; conversion requires ICC FOGRA39 profile. Missing 3D mockup before production — client approves the visualisation but the final effect on the product differs.

For T-shirt a frequent mistake is underestimating quantities — for seasonal campaigns order +10-15% buffer. For hoodie a trap is choosing the wrong decoration technique — we always proof.

For cotton bag a mistake is missing size specification in the brief — recommend 30% S / 35% M / 25% L / 10% XL split. For bandana an issue is overlooking certificates required by the end client.

For polo shirt a risk is missing Plan B for delivery — keep an alternative address. For cap the problem is brief submitted too late — minimum reasonable time is 4-6 weeks.
