Customer-supplied material can reduce the cash a shop spends on stock, but it introduces risks that a normal material purchase does not. The material may be unknown, inconsistent, contaminated, too thick, unsuitable for the laser or impossible to replace. A clear written policy protects both sides.
Approve material before quoting production
Ask for the material type, dimensions, thickness, finish and source. Test a sacrificial sample when practical. Confirm that it does not contain unknown coatings, adhesives or materials that create unsafe fumes. Follow the laser and material manufacturer's guidance and local safety requirements.
Charge for testing and handling
A test piece, settings trial, storage and extra inspection are real work. Decide whether those costs are included in a setup fee or quoted separately. If the shop must reject the material, the assessment still consumed time.
Address replacement risk
State in advance what happens if the customer's material is damaged, warped, marked inconsistently or fails during processing. The customer should understand whether the shop can replace it, whether they accept the risk and how any remake will be charged.
Example policy language
Customer-supplied materials are tested at the shop's discretion. Final results may vary with material batch, coating and internal stress. Unless otherwise agreed in writing, the customer bears the cost of replacement material if a piece is damaged during approved processing. Production will begin only after the material is approved and the proof is confirmed.
Adapt this language to local law and the actual service being sold. The goal is a specific, understandable allocation of risk—not a blanket statement that attempts to exclude every responsibility.
Record the approved sample
Keep a photo, dimensions and material description with the order records. If a later batch differs, the approved sample helps define whether the discrepancy is a production defect or a material variation.
