The hard part is rarely making the box. It’s the timing.
A single automotive component plant can carry dozens of part numbers, each needing its own packaging — cartons in different flutes and sizes, polybags in different gauges — with monthly volumes that rise and fall with the OEM’s orders. Order it all at once and your warehouse fills up with cash tied to packaging stock. Order little and often and you pay changeover costs repeatedly, and risk running out mid-run.
Vendor Managed Inventory (VMI) moves that burden to the supplier. We produce ahead, we hold the buffer stock in our warehouse, and you call it off against your production schedule. You pay when you pull stock, not when we make it.
Why it fits automotive
Assembly lines have no tolerance for late packaging. If the part is ready but the box isn’t, parts pile up — or worse, the line stops. At JMP we run corrugated cartons and PE/PP polybags under one roof, so a single call-off can ship both, on one schedule, to one QC standard. Our MOQ starts at 500 pcs, so a new part or a low-volume run doesn’t have to wait for scale.
When VMI does NOT make sense
VMI isn’t free. There’s a warehousing cost and inventory risk that we carry, and that goes into the price. So if you order one box type, once a year, at stable volume — a straight purchase is cheaper, and I’ll tell you so. VMI wins precisely when the SKU count is high and demand is hard to predict. If your line has never nearly stopped over packaging, you probably don’t need this yet.
If it has — that’s a ten-minute conversation. Send us the part spec; we’ll run the numbers first.
