How to Vet a Clothing Manufacturer: The Complete Checklist
By The Velocity Wear Team
The fastest way to protect your brand is to vet your clothing manufacturer before you place a large order — request samples, verify certifications, test communication and watch for the red flags that separate reliable partners from risky ones.
Start with a Sample Order
A sample is your quality benchmark. Order at least one sample in each garment style and colourway you plan to stock. Check stitching tension, print registration, colour accuracy against your artwork file, and fabric hand-feel. A manufacturer who resists sending samples or charges an unreasonably high sample fee is a warning sign — genuine partners expect this step.
Assess Communication Before You Order
How a supplier communicates during the enquiry stage is how they will communicate when your shipment is delayed. Measure response time, clarity of answers and willingness to answer specific technical questions about decoration methods such as screen printing, DTF, embroidery or sublimation. Slow, vague responses at the sales stage rarely improve post-order.
Certifications to Look For
- OEKO-TEX STANDARD 100: confirms fabrics are tested for harmful substances — relevant to consumer-facing brands.
- GOTS (Global Organic Textile Standard): required if you are making organic claims.
- GRS (Global Recycled Standard): required for recycled-content claims.
- ISO 9001: a quality management system certification that indicates consistent process control.
- SEDEX / SMETA: ethical audit membership, important for UK retailers and larger buyers.
Key Questions to Ask Any Supplier
- 1What is your MOQ per order and per decoration placement?
- 2What decoration methods do you offer in-house versus outsourcing?
- 3What is your standard production lead time from artwork approval to dispatch?
- 4Do you offer tracked delivery to my target markets (UK, USA, Europe)?
- 5What is your process for handling quality defects or reprints?
- 6Can you provide references or case studies from brands in my sector?
Red Flags That Should Stop You Proceeding
- No physical address or verifiable company registration.
- Pressure to pay 100% upfront before samples are approved.
- Prices that are dramatically below every competitor — quality or ethical standards are usually the cost.
- Inability to answer specific questions about their decoration process.
- Generic website photos that do not match their stated specialisms.
- No clear policy on reprints, defects or late delivery.

Due Diligence on Delivery and Logistics
Confirm tracked shipping is standard, not an upgrade. Ask which courier partners are used for your destination — whether that is the UK, USA or Europe — and what the process is if a parcel is lost or damaged. A supplier who can show you tracking from previous orders is far more credible than one who offers vague assurances.
