2 Return & Remanufacturing Policy for Custom Parts

Custom-engineered components (CNC machined parts, 3D printed prototypes, laser cut plates, custom mold inserts) are fabricated to unique customer blueprints. The following rules govern after-sales claims:

✅ Dimensional Non-Conformance

If parts deviate from approved drawings or exceed agreed ISO 2768-m tolerances as verified by CMM reports, 8btm.com guarantees 100% free expedited remanufacture or a complete refund.

✅ Material Grade Failure

If raw material fails spectroscopic or hardness analysis against specified alloy grades, the buyer receives an immediate 100% refund plus round-trip testing cost reimbursement.

✅ Surface Finish Non-Compliance

If agreed surface treatments (anodizing, electroplating, passivation, bead blasting) exhibit peeling, pitting, or color discrepancies, parts will be stripped and refinished at supplier expense.

✅ Shipping Damage Protection

In the event of deformation, thread damage, or corrosion incurred during international transit, simply provide unboxing photos within 72 hours for an immediate priority reprint or remill.
