An RFQ describes what a buyer wants. A tech pack defines what will be built and how compliance will be judged. Factories quote accurately against the second and interpret generously against the first.
1. Construction, Not Description
"Soft, natural-looking locs" cannot be produced to. "Interlocked, four-direction, 0.3cm diameter, tapered tip, 40cm relaxed length" can. Every aesthetic intention needs a construction equivalent before it enters a purchase order.
2. Measurement Method Must Be Stated
Hair length measured relaxed and length measured under tension differ, and the gap grows with curl pattern. State the method, the tolerance, and the sampling rate for inspection — otherwise a shipment can be simultaneously correct and rejected.
3. Colour Standard With a Physical Reference
Digital colour references drift across screens and lighting. Pair every colour code with a retained physical standard and state the lighting condition under which comparison is made.
4. Packing Is Part of the Product
Bundle tie, header card, bag specification, label position, and carton configuration all belong in the tech pack. They are also the most frequently changed items, so version them and record which version was approved.
5. Tolerances and the AQL Conversation
Define what deviation is acceptable and at what rate. A bulk order of thousands of units will contain variation; a tech pack that implies zero defects guarantees a dispute on the first inspection. Agree the sampling plan and the acceptable quality level before production, not at the loading dock.
6. Change Control
Any change after approval should carry a version number, a date, and a written confirmation from both sides. Most OEM disputes are not about capability but about which version of the specification was in force.
