New-parts due diligence should connect the seller's claim to the actual item and upstream source. A business can be established and responsive while still leaving important questions about manufacturer, condition or traceability unresolved. Review those questions separately from vehicle fitment, which requires the buyer's competent workshop or technical owner.

## Identify the seller and supply route

Confirm the contracting entity and whether it holds stock, obtains parts through another distributor or imports them after order. Ask what source is proposed for the quoted item and whether the supplier may change it. The buyer needs a commitment for the actual purchase, not only a description of the company's wider sourcing network.

Verify relevant business information through established controls. Where manufacturer authorisation is claimed, use the manufacturer's appropriate official channel to check that claim. Do not assume that a logo on a website or invoice establishes an authorised relationship.

## Examine the product description and evidence

Record the manufacturer, part number, unused condition and agreed packaging. Ask the seller to explain terms such as genuine or OEM for the item. Review the evidence it can provide to support the source claim and how that evidence will remain connected to the delivery.

For example, a quotation may identify a vehicle manufacturer while the invoice later uses only a generic component description. Require the final record to preserve the actual manufacturer and part reference. The loss of detail can make a later sourcing or mismatch investigation unnecessarily difficult.

## Review change and support controls

Ask how substitutions, supersessions and source changes are disclosed. Identify the person who can obtain technical clarification from the relevant source and the process for dealing with a suspected wrong or damaged item. Clarify return and warranty conditions before the buyer commits to a special order.

Where product-specific conformity questions arise, have the supplier identify the relevant current requirement and route it to a competent reviewer. Avoid treating a generic certificate as proof for every part or assuming that all products fall under the same scheme.

## Keep the approval bounded and reviewable

Combine source review with representative orders and comparable references. Record brands, part families, approved sourcing arrangements and limitations. Revisit the relevant checks when those arrangements change materially. Due diligence supports reliable purchasing when it preserves a clear trail from the offered item to the delivered part, rather than relying on broad reputation or packaging appearance as a substitute for evidence.
