What is custom apparel and garment manufacturing? Custom apparel and garment manufacturing is the process of producing clothing, uniforms, workwear or branded garments made to your specifications — including your choice of fabric, cut, colour, logo and labelling. For UK businesses, this typically means working with factories in China or Vietnam to manufacture products at scale from approved samples or technical packs.
The UK market for custom clothing and uniforms spans corporate workwear, hospitality uniforms, sports and leisurewear, branded merchandise, and independent fashion labels. Rather than buying off-the-shelf garments, UK brands increasingly turn to contract garment manufacturers in China and Vietnam to create products that are entirely their own — with better margins, consistent quality, and full ownership of the design. This shift has accelerated as minimum order quantities (MOQs) from Asian factories have fallen significantly over the past decade, making custom manufacturing viable even for smaller brands placing orders of 300–500 units per style.
Working directly with a garment factory — rather than through a third-party wholesale platform — means you control the specification, the fabric composition, the branding, and the compliance documentation your product carries into the UK market. For businesses supplying uniforms to schools, NHS contractors, hospitality groups or corporate clients, this level of control is not optional: it is required both by your clients' procurement standards and by UK product safety regulations that apply to textiles, PPE, and technical workwear.

UK textile imports must comply with several overlapping regulatory frameworks. The UK Textile Products (Labelling and Fibre Composition) Regulations 2012 require all garments sold in the UK to carry a fibre content label in English, identifying each fibre by its legal name and percentage. This is the most basic requirement and one that many first-time importers overlook when ordering from factories that default to EU-market labelling.
For garments that constitute Personal Protective Equipment (PPE) — hi-vis workwear, flame-retardant clothing, cut-resistant gloves, or safety footwear — the Personal Protective Equipment (Enforcement) Regulations 2018 require UK market placement to carry the UKCA mark. Factories must provide a Declaration of Conformity and evidence of third-party EN-standard testing. Importing non-compliant PPE is a criminal offence in Great Britain. UK REACH also applies to certain dye chemicals and finishes: if your garments use azo dyes, formaldehyde finishes, or certain flame retardants, suppliers must confirm these are within UK REACH substance limits.
⚠️ UKVFTA Rules of Origin Warning
To benefit from reduced UK import duty under the UK–Vietnam Free Trade Agreement (UKVFTA), garments must meet the double transformation rule of origin. This means both the fabric must be woven and the garment cut and sewn in Vietnam — simply sewing Chinese fabric in Vietnam is insufficient. Ask your sourcing agent to obtain a EUR.1 certificate for every UKVFTA shipment.
| Product Type | Typical MOQ | Sample Lead Time | Bulk Lead Time | Indicative FOB Price |
|---|---|---|---|---|
| Corporate polo shirt (embroidered) | 300 units | 2–3 weeks | 45–60 days | £4.50–£8.00 per unit |
| Custom chef/hospitality uniform set | 100 sets | 3–4 weeks | 60–75 days | £12–£22 per set |
| Hi-vis workwear (UKCA, EN ISO 20471) | 500 units | 4–6 weeks | 70–90 days | £8.00–£14.00 per unit |
| Custom activewear set (sublimation print) | 200 sets | 2–3 weeks | 40–55 days | £9.00–£18.00 per set |
| School uniform (polo + sweatshirt, embroidery) | 500 units | 3–4 weeks | 60–80 days | £3.50–£6.50 per unit |
Most garment factories in China require a minimum of 300 units per style per colour for standard woven or knitted garments. For more complex items — such as tailored uniforms with multiple components — MOQs can rise to 500–1,000 units. Some specialised factories, particularly in Vietnam, work with MOQs as low as 100 sets for hospitality or corporate uniform programmes. A sourcing agent can negotiate lower MOQs for new clients in exchange for a higher unit price or a commitment to repeat orders.
The UK–Vietnam Free Trade Agreement (UKVFTA) reduces UK import duty on qualifying Vietnamese-made garments from the standard Most Favoured Nation (MFN) rate of 12% to preferential rates that in many cases fall to 0–9.6%, depending on the commodity code. The saving is significant for high-volume orders: on a £100,000 garment shipment, a 12% duty saving represents £12,000. To qualify, the garment must meet the double transformation rule of origin — both the weaving of the fabric and the cutting and sewing must take place in Vietnam. Your sourcing agent should confirm eligibility for each product before you claim the preference at UK customs.
All garments sold in the UK must carry a fibre composition label in English, listing each fibre by its legally prescribed name (e.g. 100% Cotton or 65% Polyester, 35% Cotton) and the full percentage of each. Care instructions are not legally required by UK law but are expected by UK retailers and required for professional garments governed by British Standards. Country-of-origin labelling is not required for textiles under current UK law, though many retailers and corporate buyers request it. For PPE garments, a CE or UKCA mark, EN standard reference, and size markings are required by law.
In some cases, yes — particularly for larger garment factories that have in-house packaging operations or long-standing relationships with nearby packaging suppliers. However, it is more common for garment factories and packaging suppliers to operate separately, and sourcing both through the same factory introduces risk if either side underperforms. A sourcing agent can coordinate both garment manufacturing and packaging procurement on your behalf, consolidating both into a single shipment to reduce freight costs.
A realistic timeline from initial brief to bulk shipment arriving at a UK port is 14–20 weeks. This breaks down as: 1–2 weeks for factory selection and quoting; 2–3 weeks for the first sample; 1–2 weeks for client review; 2–3 weeks for a second sample if needed; 1 week for approval; 8–10 weeks for bulk production; and 3–5 weeks for sea freight from China or Vietnam to Felixstowe or Southampton. Air freight reduces transit to 5–7 days but adds significant cost. Planning your order cycle at least 4–5 months ahead of your required delivery date is strongly recommended.
For UK businesses with ESG commitments or clients requiring supplier ethical audits, the key certifications to look for are BSCI (Business Social Compliance Initiative), SMETA (Sedex Members Ethical Trade Audit), and SA8000. In Vietnam, the ILO Better Work programme provides government-backed factory compliance with international labour standards. Most factories exporting to major European or UK brands will hold at least one of these audits. When working with Epic Sourcing, we request audit reports directly from factories and advise on which standard aligns with your corporate procurement requirements.
