For an American mahjong project, ask for quality evidence tied to the complete approved set. Tile counts, face assignments, print appearance and accessory fit need separate checks. One material test cannot establish the quality of the finished collection.
Define observable acceptance criteria
Identify critical tile faces, approved artwork and the quantities of each piece. Use a drawing for dimensions and specify where measurements are taken. Compare colours with an agreed reference and viewing conditions. Avoid adopting unexplained numerical tolerances from a generic online checklist.
Request traceable inspection results
A useful record names the product revision and batch, shows the inspection method and records actual observations. Ask how measuring equipment is checked and how nonconforming items are separated. If sampling is used, agree the selection and acceptance rules before inspecting the shipment.
Close the loop on defects
Keep photos of missing faces, edge defects, print problems or fit failures with their batch references. Ask for the proposed correction and its verification. A sample of accepted goods is a comparison reference, not evidence that all later batches will be identical without inspection.
Prepare the next decision
Next, review sample approval checklist alongside your current brief. Review the custom American mahjong set project page or send a project question with the relevant drawings, photographs and open decisions.
