A Practical RFQ Checklist: Drawings and Specs That Get You an Accurate Quote

The fastest quotes are not the ones chased hardest — they are the ones backed by complete information. A manufacturability review is only as good as the drawing behind it.

What to attach

• A 3D model (STEP/IGES) plus a 2D drawing with all critical dimensions and tolerances called out.
• Material grade and any specification (e.g. AISI, EN, or your internal spec number).
• Surface finish, heat treatment and plating/coating requirements.
• Annual volume and target order quantity — this changes the recommended process.
• Any features that are function-critical, so we prioritise them in inspection.

What slows it down

Vague notes like “as per sample” without the sample, or tolerances applied to every dimension, force us to ask questions. The clearer the intent, the tighter the price and the lead time.
