RFQ checklist for CNC parts sourced from Mexico
An incomplete RFQ produces quotes you can't compare. This checklist covers what a machining supplier needs to price your part accurately.
- Core package: drawing with tolerances, material, quantity and annual volume.
- Often forgotten: inspection requirements, finish, packaging and delivery terms.
- Compliance: confirm export-control status before sharing drawings outside the U.S.
- Goal: quotes that are complete and comparable.
1. Drawing and model
- Current 2D drawing with revision level, tolerances and datums.
- 3D model if available, with a note on which document governs when they differ.
- Critical-to-quality features called out clearly.
2. Material and finish
- Material specification and any required material certifications.
- Surface finish, coating or heat-treatment requirements, and whether a special process is performed by the shop or a separate processor.
3. Quantity and volume
- Quantity for this order and expected annual volume — volume changes which shop is the best match and how it prices.
- Whether this is a prototype, a first article or a repeat production part.
4. Inspection and documentation
- Inspection method and sampling plan you expect.
- First-article or dimensional report requirements.
- Certificates of conformance or other documents to ship with the parts.
5. Packaging, delivery and timeline
- Packaging and labeling requirements.
- Ship-to location and delivery terms.
- Target lead time and any hard deadline.
6. Compliance check before you send anything
Confirm the export-control status of your drawings and technical data with your compliance team before sharing them with any supplier outside the United States. Arzen cannot make that determination for you.
| Item | Why it matters |
|---|---|
| Drawing, revision, tolerances | The shop prices what it can see; missing tolerances become assumptions. |
| Material and finish | Drives cost, lead time and which processors are needed. |
| Quantity and annual volume | Determines fit, tooling approach and unit price. |
| Inspection and documents | Avoids surprises when the first lot arrives. |
| Delivery terms and timeline | Makes quotes comparable. |

Frequently asked questions
What is the minimum I need to get a quote?
A drawing with tolerances, the material, the quantity and your target timeline. More complete packages get more accurate quotes.
Do I need a 3D model?
A 3D model helps but the controlled 2D drawing should state which document governs.
Can I send drawings that are export-controlled?
Confirm export-control status with your compliance team before sharing technical data with any supplier outside the United States.
