- Part identity
- Ask for model-specific drawings, catalog references, inner diameter, width, bolt pattern, pilot hole and surface finish. An OE reference identifies a candidate; it does not transfer vehicle-maker rights to this sourcing desk.
- Supply condition
- Clarify new versus remanufactured drums, core charge terms and whether the quoted item is a single drum or a hidden kit. Those choices change both price and acceptance tests.
- Order evidence
- Ask for sample scope, batch identifiers, packing unit and gross package weight. Sample approval is not automatic approval of later production batches.
- Quote boundaries
- Confirm validity period, freight, taxes, service scope, warranty scope and exclusions. No savings percentage is published here because this site has no same-basis market comparison on file.
