A sample gives you something concrete to compare with the product listing and your own requirements. Before ordering it, write down the exact variant, dimensions, material description, colour and intended use. Ask whether the sample comes from the same specification and packaging planned for the bulk order. Keep the product link, date and supplier’s written answers together.
When the sample arrives, photograph the sealed parcel, packaging and product. Check the quantity, visible finish, measurements, moving parts and any included accessories. Try it under the conditions relevant to your business, without treating a successful trial as proof of every claimed performance or certification. Record both acceptable details and issues, with clear photos rather than general impressions.
Send the supplier a short list of required changes and ask for written confirmation. If a change affects the material, construction or fit, consider another sample before committing. Keep an approved reference sample and an agreed inspection checklist for the order. A sample can reduce uncertainty, but it does not guarantee that every unit in a future shipment will be identical.
