Start with the specification, not the catalogue photograph
A supplier photograph can show colour and general construction, but it cannot prove split fibre, blend ratio or wash durability. Send the same short specification to each supplier: finished size, GSM, blend, weave, edge, colour reference and retail pack. The answers become comparable before price enters the discussion.
Verify the fibre and the blend
Ask whether a split-fibre statement applies to the selected fabric and how it is supported; do not assume a particular splitting route. Write the full fibre names with the percentages and keep construction, GSM, size and preparation aligned in sample comparisons. An 80/20 or 90/10 ratio alone does not establish absorbency, durability or value.
Control the sample-to-production gap
Keep one approved physical sample with the order reference. Ask the supplier to retain a matching reference and to explain how a repeat order is checked against it. A sample from premium stock is not evidence that every later batch will use the same yarn, edge or finished size.
Check packing and buyer documents
A retail range needs more than a cloth. Confirm pack count, sleeve or bag format, carton dimensions, gross weight, barcode space and the destination-market marking requirements. Ask for the material declaration and the product code on every document so the packaging artwork cannot drift to a different construction.
A specification you can send today
Send the item code or construction, full material composition, size, colour, selling pack, quantity per item and colour, destination market and target arrival date. For a custom order, identify whether the logo goes on the cloth, label or packaging, and ask the supplier to confirm the print method and limitations. Use the microfiber private-label RFQ template to request comparable quotations. Separate unit price, artwork or setup charges, custom sample costs, packing, Incoterm and freight basis; do not compare a delivered price with an EXW quote as if they cover the same costs.

Keep a sample-approval record
Use one record containing item and colour, full material declaration, construction, dimensions, GSM if applicable, edge, pack and sample revision. Add the intended surface and care routine, the checks agreed with the supplier and any acceptance limits. Mark results as pending until evidence is available.
Keep the product approval, final colour approval and packaging artwork approval traceable to that record. Before production, ask the supplier to identify any specification that differs from the retained reference. A signed picture or catalogue number alone does not record every approval condition. For an initial shortlist, compare our custom microfiber cloth starting products and put the selected codes on the same approval record.
