Imported components: tracking them from receipt to the production line

A Korean-owned plant in Uzbekistan often builds its product from parts that arrive from several countries, and the parts for one purchase order may come in several shipments. Before a part reaches the line it passes the receiving dock, an inspection area, the main store and a rack beside the line. At each handover someone can lose a carton or its paperwork. When a quality problem or a shortage appears, the questions are always the same: which lot, where is the rest, and how much was used? A lot-based trail answers them with one kind of label and a few checkpoints.

Where the trail usually breaks

• One order arrives in three partial shipments, and the packing list of the first is treated as the list for all of them.
• Cartons are opened and repacked at the dock, and the supplier label ends up on the wrong carton or disappears.
• Parts waiting for inspection stand in the aisle with no status and are sometimes drawn into production before release.
• Kits are issued to the line, the leftovers are neither returned nor recorded, and the stock beside the line becomes invisible.
• Two supplier lots of the same part are mixed in one bin because they look the same.

Customs formalities and import documents are outside the scope of this article; ask your customs broker or accountant about them. What matters here is that the document reference travels with the goods.

An internal lot label at the dock

Do not rely on the supplier label alone. Formats vary, and they rarely match the form your own system uses. At receiving, print an internal label for each carton or pallet. It carries your part code, the supplier lot or batch number, the quantity, the date received, the document reference (order or delivery note) and the status (hold or released). The lot number is encoded as a barcode. Leave the supplier label where it is and put the internal label beside it, without covering the original.

Four handovers, four scans

At each handover both sides scan.

1. Dock to inspection or hold area: the receiver scans the label and leaves the status on hold.
2. Inspection to main store: the status changes to released, and the storekeeper scans the lot label and the location label.
3. Store to line: the issue is made against a work order or a kit, and the line operator scans the quantity actually taken.
4. Line back to store: leftovers go back, or are declared as scrap with a reason, each with a scan.

Every scan records who handled what, where, when and how many. The point is that no lot is ever "somewhere in between" without a record. If a cart is standing in the aisle, it is the responsibility of the person whose name is on the last scan.

Checking the balance of each lot

For every lot, the quantity received should equal the sum of store stock, stock beside the line, quantity used, scrap and returns. Use can be calculated from production output and the bill of materials, or taken from the line's own records.

For illustration, take connector lot L-0417. It arrives in three deliveries of 5,000, 4,000 and 3,000 pieces, and all 12,000 are released. The line is issued 9,500. Use calculated from output is 9,100, recorded scrap is 40 and the count beside the line finds 340. That adds up to 9,480, which is 20 short of what was issued. The store should hold 2,500, which is counted separately. Twenty pieces is 0.2% of the issue, but it still needs a reason: a miscount at the line, or scrap that nobody wrote down. Settle the acceptable tolerance before the count, not after it.

Summary

Managing imported components does not mean trusting what the supplier printed; it means being able to say at any moment where each lot is inside your own walls. Smart Inventory counts the dock, the inspection area, the store and the line-side racks in the same way, using label printers and handheld scanners, compares the results with your records and sorts the differences by cause.
