Amazon FBA preparation happens at the supplier, before the cartons reach a port or a fulfilment centre. Carton plans, SKU matrices, labels, packing lists and consolidation all have to agree before dispatch, because a mismatch found at the fulfilment centre is harder to fix than one found at the bench.

1. Preparation starts at the supplier, not at the port

An Amazon FBA shipment is decided at the packing bench. The cartons, the labels, the SKU data and the packing list are all created at the supplier, and the fulfilment centre can only receive what the supplier prepared correctly. A carton with the wrong label, a count that differs from the shipment data or a mixed SKU in a carton declared as a single SKU will hold the shipment at the fulfilment centre, where a fix means rework, storage or a return. The same error found at the supplier is a new label and a recount.

Preparation is a pipeline, not a single check. The carton plan states how many cartons, which SKUs go in each one and how many units of each SKU. The labels identify each carton and its contents. The packing list records the cartons, the quantities and the weights. Consolidation brings several suppliers together into one shipment, and the CFS cutoff sets the last point at which the cargo can be accepted for a sailing. Each step feeds the next, so an error in the carton plan becomes an error in the labels, the packing list and the shipment data. This guide follows that pipeline in order.

2. Carton plans and SKU matrices

A carton plan is a table, not a guess: each carton has a number, a SKU list, a unit count per SKU and a packed weight. A SKU matrix goes further and maps every model to its package count — for lithium battery products, each battery model has its own row, with the watt-hour rating, the battery count and the carton it travels in. Power tools with spare batteries need the same treatment: the tool, the spare battery and the charger each have their own line, because the fulfilment centre counts them as separate items. Build the matrix before packing starts, and pack from the matrix rather than from memory.

Different products need different carton logic. Shoes and apparel pack by size and colour, and the carton plan must keep sizes together so the fulfilment centre can receive them without opening every carton. Glassware and LED lighting need the carton strength and the protective packing stated in the plan, because a broken unit in transit becomes a shortage at receiving. Kitchen knife sets and utility knives with replacement blades need the full kit declared — the blades are part of the product, not an accessory to be left off the packing list. Synthetic wigs pack by volume, so the carton dimensions matter as much as the count. Whatever the product, the rule is the same: the carton plan describes the cartons that will actually be packed, and the packing list is rebuilt from the packed cartons, not copied from the order.

3. Labels and shipping marks

Every carton in an FBA shipment carries two kinds of identification. The FBA carton label identifies the shipment and the contents for the fulfilment centre, and the shipping mark identifies the carton for the forwarder, the carrier and customs: the consignee, the carton number, the SKU and the quantity. Both must be printed clearly, placed where the scanner can read them and checked against the carton plan before the cartons leave the supplier. A label printed for the wrong SKU, a mark that is smudged or a carton number that skips a number will slow receiving and invite a full count.

Labels deserve a photo check. Ask the supplier to photograph the labels on the finished cartons and the marks on the master cartons, and compare the photos with the carton plan and the shipment data while the goods are still at the supplier. Check the SKU on each label, the carton number sequence and the quantity on each mark. A label error found in a photo costs a reprint; the same error found at the fulfilment centre costs a receiving hold. Keep the photos with the shipment file, because they are the evidence that the labels were correct when the cartons left the supplier.

4. Packing lists and quantity reconciliation

The packing list is the document the whole chain checks against: the forwarder, the carrier, customs and the fulfilment centre all compare the cargo with the packing list. It must list every carton, the SKUs and quantities inside it, the packed weight and the dimensions, and it must match the commercial invoice. Reconcile the invoice quantities with the packing list before the shipment leaves: the invoice states what was sold, the packing list states what was packed, and the two must describe the same goods in the same quantities. A difference between them — a unit count that differs, a SKU that appears on one document and not the other — will be found at the first check, and it will hold the shipment while someone finds the error.

Reconciliation is a comparison, not a copy. Build the packing list from the packed cartons, count by count, and then compare it with the invoice line by line. Check the carton count, the total unit count per SKU, the weights and the marks. If a count differs, find the cause before dispatch: a carton packed from the wrong matrix row, a unit moved between cartons without updating the plan, or a SKU that was substituted without updating the invoice. Correct the source — the carton plan or the invoice — and rebuild the documents from the corrected source, so every document in the file describes the same shipment.

5. Consolidation across suppliers and SKUs

Many FBA orders come from more than one supplier: one factory makes the product, another makes the packaging, a third supplies an accessory. Consolidation brings those separate orders together at one warehouse in China, checks them, repacks them into a single shipment and sends them on as one consignment. Each supplier’s cartons should be counted and labelled on arrival at the consolidation warehouse, and the count should be reconciled against each purchase order before anything is repacked. Repacking changes the carton count, the weights and the marks, so the packing list and the shipment data must be rebuilt from the repacked cartons.

Mixed cargo needs a clear decision before consolidation. Sensitive and general cargo can share a consolidated shipment only when the carrier and the fulfilment centre accept the combination, and the sensitive items — lithium batteries, perfume, aerosols, cosmetic liquids — need their own documentation, packing and carton separation inside the shipment. Multiple perfume SKUs, lithium battery products mixed with electronics, and vape devices with batteries and liquid each need a SKU-level review before they are packed together, because a single undeclared item can hold the whole consignment. State the full SKU list, the battery data and the liquid data in the consolidation plan, and ask the forwarder to confirm the combination before the cartons are packed.

6. CFS cutoffs, leak protection and breakage

For LCL (less-than-container-load) shipments, the cargo is received at a container freight station (CFS), where the container is loaded and the cargo is sorted by consignee. The CFS cutoff is the last point at which cargo can be accepted for a sailing, and cargo that arrives after the cutoff waits for the next sailing. Preparation must work backwards from the cutoff: the cartons packed, the labels checked, the packing list reconciled and the cargo delivered to the CFS with time to spare. Confirm the cutoff and the CFS receiving requirements with the forwarder before the cargo leaves the supplier, and build the transport plan around the cutoff rather than around the sailing.

Leak and breakage protection is part of preparation, not an afterthought. Perfume, cosmetic liquids and aerosol cans need leak-proof packing: sealed inner bags, absorbent material, upright orientation and carton strength that survives stacking. Aerosol valves need protection so the valve cannot be pressed during transit, and glassware needs dividers and cushioning that keep each piece separate. Test the packing on a sample carton before the full run: fill it, seal it, shake it and stack it, and check for leaks, movement and damage. A packing method that fails the sample test will fail across the whole shipment, and the failure will be found at the fulfilment centre, where the leaked or broken units become a shortage.

7. How to request an FBA shipment preparation review

A useful review request reads like a shipment file, not a question: the product and the SKU list, the carton plan and the SKU matrix, the labels and the shipping marks, the packing list and the invoice, the consolidation plan and the destination fulfilment centre. With that data, a forwarder can check the preparation, the labels, the counts and the transport plan and confirm what is still missing — without it, any answer is only a general estimate.

Treat every reply the same way: confirm the scope in writing — who checks the labels, who builds the shipment data, who books the CFS delivery and the transport, which charges are separate, and what happens if the count does not match or the delivery is refused. An inquiry or estimate is not a booking, and a carton plan is not a receiving confirmation until the fulfilment centre receives the goods. Keep the written confirmation with the shipment file and check it against the loading photos before the goods leave the supplier.

Frequently asked questions

What should be ready before an FBA shipment leaves the supplier?

The carton plan, the SKU matrix, the printed labels and shipping marks, the packing list reconciled against the invoice, and the shipment data that matches all of them. The fulfilment centre checks the shipment against that data on arrival, so a label or count error found at the supplier is a quick fix, while the same error found at the fulfilment centre can hold the whole shipment.

How do I keep carton quantities consistent across the invoice, the packing list and the FBA shipment data?

Build the packing list from the packed cartons, count by count, and then compare it with the invoice and the shipment data line by line: the carton count, the total unit count per SKU, the weights and the marks. Correct the source document when a count differs, and rebuild the other documents from the corrected source, so every document describes the same shipment.

Can sensitive and general cargo be consolidated into one FBA shipment?

It depends on the carrier and the fulfilment centre. Sensitive items such as lithium batteries, perfume, aerosols and cosmetic liquids need their own documentation, packing and carton separation inside the shipment. State the full SKU list and the battery and liquid data in the consolidation plan, and ask the forwarder to confirm the combination before the cartons are packed.
