05 / Buyer questions

Before you submit a brief

Is a frequency match enough?

Ask for the exact vehicle and market entry, supported programming route and valve interface. A common frequency leaves those questions open.

Can we compare stock and custom packs?

A stock pack follows the supplier’s existing component mix. A custom pack can follow your assortment and labeling, with separate sample, minimum order quantity and setup review.

What changes if we use several suppliers?

One supplier can simplify pack and lot records. Several suppliers can cover more of a fitment list, with more work to align sample records, carton markings and shipment handoffs.

When are commercial terms confirmed?

After suppliers respond to the part, pack and quantity brief. Review the quoted minimum, dispatch basis and delivery term on each line before placing an order.

Put the hard-to-match line first

Start with one reference, the intended vehicle and the quantity. Add a drawing or packaging requirement to the brief when it affects the quote.
