CMR for Consolidated Cargo: One Waybill for Multiple Invoices

What Counts as Consolidated Cargo — and How the CMR Applies

Consolidated cargo (also called groupage or LTL — less-than-truckload) is a shipment where goods covered by several commercial invoices travel together in one vehicle. Two situations look similar but are treated very differently under the CMR Convention:

One sender, one consignee, many invoices. A supplier ships goods from three orders to the same buyer in one truck. This is a single transport contract — one CMR covers everything, with all invoices listed in Box 5.
Many senders or many consignees in one truck. A classic groupage line hauling for five different recipients. Each sender–consignee pair is a separate transport contract — each needs its own CMR, even though the goods share a trailer.

The rule of thumb: one CMR per transport contract, and a transport contract is defined by the sender, the consignee, and the delivery address. The number of invoices behind the shipment does not multiply the CMRs — but the number of recipients does.

Getting this split wrong in either direction causes problems. One CMR stretched across several consignees makes carrier liability unenforceable and fails at customs; separate CMRs for what is legally one consignment inflate paperwork and create contradictory totals.

Filling Out a Multi-Invoice CMR: Field-by-Field Rules

A consolidated CMR uses the same 26 boxes as any other — see our complete field-by-field guide — but five fields require special attention when several invoices stand behind one waybill:

Box	Field	Rule for consolidated shipments
5	Documents attached	List every invoice number and date, plus packing lists and certificates. Each document must be identifiable from the CMR alone.
6	Marks and numbers	Marks from all invoices, matching the physical labels on each pallet or package group.
7	Number of packages	The aggregated total across all invoices — e.g. '18 pallets', not three separate counts.
9	Nature of goods	Every commodity type listed explicitly, or a reference to an attached packing list as an integral annex. Never 'mixed goods'.
11	Gross weight (kg)	The combined gross weight of all invoice lines, including packaging. Must equal the sum of the attached documents.

For long commodity lists, standard practice is to write a short summary in Box 9 (e.g. "General cargo per attached packing list — 6 commodity types") and attach the packing list itself, referencing it explicitly in Box 5. The annex then legally forms part of the consignment note.

If any line in the consolidation is dangerous goods, its UN number and ADR class must appear in Box 9 — the presence of ordinary cargo around it changes nothing about the declaration requirement.

Six Groupage CMR Mistakes That Stop Trucks at the Border

Consolidated shipments are over-represented in customs inspections for one reason: their paperwork has more moving parts, so it fails more often. These are the recurring failures we see:

One CMR for multiple consignees

A CMR is a contract of carriage with one consignee. Covering deliveries to different recipients with a single document makes liability unenforceable and will be rejected at customs. Issue one CMR per consignee, even if everything travels in the same truck.

Missing invoice numbers in Box 5

If a customs officer cannot match an invoice found in the cab to the CMR, the whole vehicle is flagged for inspection. Every accompanying invoice, packing list, and certificate must be listed with an identifiable number.

'Mixed goods' as the cargo description

Box 9 must allow customs to identify what is actually on board. Summarising ten commodity types as 'consolidated cargo' is the single most common trigger for physical inspection of groupage trucks.

Totals that don't add up

The gross weight in Box 11 and package count in Box 7 must equal the sum of the attached invoices. Copy-paste and manual addition errors here create discrepancies that surface at the weighbridge — with the vehicle detained until documents are corrected.

Forgetting the packing list annex reference

When Box 9 references an attached packing list instead of listing goods inline, that packing list must be named in Box 5 and physically accompany the consignment. A referenced-but-missing annex invalidates the description.

Mixing ADR and standard goods without declaration

If any invoice line in the consolidation includes dangerous goods, the UN number and ADR class must appear in Box 9 regardless of how small that line is. An undeclared ADR item inside a groupage load is a serious offence for both sender and carrier.

Merging Multiple Invoices into One CMR Automatically

The manual workflow for a multi-invoice CMR — open each invoice, copy line items, add up weights and package counts, retype every invoice number into Box 5 — is exactly where arithmetic and transcription errors breed. It is also entirely automatable.

Logi Link Up handles consolidation natively: upload up to 10 invoices for one shipment, and the AI extracts the data from each document, then merges everything into a single CMR:

Aggregated totals, computed

Gross weight and package counts are summed across all invoices — no calculator, no transposition errors in Box 11.

Box 5 filled automatically

Every invoice number and date lands in Documents attached, formatted and complete.

Goods descriptions combined

Line items from all documents are merged into a customs-ready description for Box 9.

In-memory merge with privacy mode

The entire merge can run without a single database write — documents are processed and discarded, nothing is stored.

Works with your custom templates

The merged data fills your own CMR blank, with dedicated placeholders for up to 10 invoice references.

The result is a print-ready CMR where the totals are guaranteed to equal the sum of the attached documents — closing off the single largest source of groupage border inspections.

Frequently Asked Questions About Consolidated CMR Shipments

Can one CMR cover several invoices?+

Yes — provided the goods travel in one vehicle, from one sender to one consignee, under a single transport contract. All invoice numbers must be listed in Box 5 (Documents attached), and Boxes 7, 9, and 11 must contain the aggregated package count, full goods description, and combined gross weight.

When do I need separate CMRs instead of one?+

A separate CMR is required for each consignee and each delivery address. If a groupage truck carries goods for five different recipients, it needs five CMRs — one per transport contract. One consignee receiving goods from several suppliers at one address can usually be covered by one CMR per sender.

How do I describe mixed goods in Box 9 of the CMR?+

List each commodity type explicitly — for example 'automotive spare parts; hand tools; packaging film' — or attach a packing list and reference it in Box 5 as an integral part of the consignment note. Writing 'consolidated cargo' or 'mixed goods' alone is insufficient for customs identification and invites physical inspection.

Whose weight goes into Box 11 for a multi-invoice shipment?+

Box 11 must show the total gross weight of the entire consignment — the sum of gross weights across all invoices and packing lists, including packaging and pallets. If the declared total deviates from the weighbridge figure by more than roughly 5%, customs can detain the vehicle for reweighing and document correction.

Can software merge several invoices into one CMR automatically?+

Yes. Logi Link Up accepts up to 10 invoices per shipment, extracts line items, weights, and references from each, and merges them into a single CMR with aggregated totals and every invoice number listed in Box 5. The merge can run entirely in memory in privacy mode, with no documents stored.
