ASBX Portugal is a B2B clothing manufacturer specializing in luxury blanks, private label apparel, and fully custom garments for international brands. We combine craftsmanship, sustainability, and innovation to deliver premium-quality garments made in Portugal.
Barcelos sits at the centre of Portugal’s most concentrated textile cluster — Guimarães, Famalicão, and Braga within 30 km. ASBX draws on this ecosystem for specialised finishing, yarn, and hardware without long logistics chains.
From fabric sourcing and sample development to decoration, wash, QC, and global export — ASBX manages the full production cycle. No fragmented vendor management for brands.
Produced in Portugal, ASBX goods carry EU origin, avoiding the tariff exposure that Asian-manufactured competitors now face in the UK and US markets. A structural cost advantage in 2025–2026 trade conditions.
Streamlined intake, in-house sample production, and real-time order tracking compress timelines that typically run 12–16 weeks at larger Portuguese factories down to 3–7 weeks at ASBX.
ASBX serves over 3,000 active clients across more than 100 export markets, with particular depth in the UK, USA, EU, and Gulf. Clients include streetwear startups, established luxury labels, private label retailers, corporate clients and private costumers.
In-house knitwear capability using 3D knitting machines and computer-controlled looms for jacquard, cable, and seamless constructions — rare for a manufacturer also offering full jersey and fleece production.
