Freight Surcharge Families, From Origin To Destination

Two consignments can move the same weight, on the same lane, in the same week and land on invoices with different totals. The base rate is the smaller part of that gap. What sits on top is a family of line items, each with its own trigger, and most billing disputes are about whether a trigger fired.

Key facts

• Two separate places. Origin charges are set by the tariff in force when the cargo is tendered to us; destination charges by the tariff in force when it arrives. A booking made in one month can be billed in another.
• Peak surcharges are announced. A demand surcharge is published against a named trade lane with an effective date — knowable before you book, as a structure rather than an amount.
• Cube drives most of it. Billable weight, volumetric weight and the excess categories above both are three triggers that start from the same outside dimensions.

Where the surcharges come from, in order

Think of a movement as a sequence of handovers rather than one service. The quoted rate is the line-haul segment. Before it, cargo is collected, measured and built in China; after it, the box is cleared, deconsolidated and handed to a final-mile network. Each handover belongs to a different party, and each prices what it controls. That is why surcharges attach in two places: an origin item is fixed while cargo is in our hands, the version we can verify before booking; a destination item is fixed weeks later against a tariff that may have changed.

Origin-side families

Collection from a supplier is its own chargeable leg, quoted per factory address. Distance, access and waiting time differ enough between a Pearl River Delta estate and an inland supplier that one blended figure would be fiction for half of all bookings.

The second family is build. Carton cube and the channel's mass limit set how many pieces fit a unit load; palletisation and crating are separate decisions; where timber packaging is used, the ISPM-15 mark is a compliance precondition, not an optional service. Our floors measure each consignment at goods-in, because that measurement is what the destination bills against later. A third family is export-side documentation: which filing the lane requires, and whether its data was ready before the cargo moved.

Weight families and what cube actually drives

Most disputes start here, so keep three things apart. Billable weight is the larger of actual weight and volumetric weight. Volumetric weight is a box's outside dimensions divided by a channel-specific factor. Excess categories sit above that and are triggered by individual piece size or mass, not by the total — a consignment can be light, under the per-piece mass limit, and still fall into an oversize category because one carton is long.

Two of those five rows are ours to control; the other three are not. That is why we measure at goods-in instead of estimating from a supplier's product sheet.

Destination-side families

At the far end the charges stop being about the box and become about the address. Location type decides whether a parcel goes to a commercial dock or a residential doorstep, and networks price those differently. An appointment, a tail-lift or an inside-delivery request attaches to the destination's capability, not the origin's. Remote-area categories come from the network's own postcode list. Customs-side items — inspection, holding, a filing correction — are triggered by the entry rather than the freight order. A warehouse in Dongguan cannot decide any of those; what we can do is refuse the combination that creates them.

What is announced in advance, and what is not

Surcharge families divide cleanly by whether they are published before they are charged. Fuel and demand-driven items are announced: a peak surcharge appears against a named trade lane with an effective date, and a fuel adjustment is re-published on its own cycle. Other categories are properties of your cargo: an oversize trigger follows from dimensions, a residential trigger from an address, a handling trigger from packaging. Those can be computed before booking, which is what the five questions below are for.

Five questions that decide the destination invoice

• Which tariff applies on the day my cargo is tendered? Ask for the version, not a promise that nothing will change.
• What are the outside dimensions of each piece after packing? Not the product size — the packed carton, including protective outer.
• Is my destination commercial or residential? That fact alone can move a shipment into another charge family with no change in weight.
• Will the order ship as one parcel or several? Per-piece charges multiply; per-order charges do not.
• Which families attach at origin and which at destination? If it is not written down, the invoice will answer it later.

What we do not do

We do not publish amounts for these families. Structure is what a public page can carry; the number depends on a lane, a date, a tariff version and a measurement, and is confirmed in writing before cargo moves. We do not absorb a charge we cannot foresee, and we do not represent that a surcharge announced while your cargo is in transit will not apply. Send the packed dimensions, the destination type and the build you have been quoted and we will mark which families above can fire on that lane: tony@sbt56.com, or the enquiry form at Contact.

Are a fuel charge and a demand charge the same line?

A fuel adjustment compensates a carrier for the energy cost of moving cargo and is re-published on its own cycle against a reference price. A demand surcharge is a capacity instrument: announced against a named lane for a stated window, when booked volume runs ahead of available space. Both are separate line items, and both can apply in the same month — which is why an unchanged freight rate does not mean an unchanged total.

Can you tell me before booking whether a surcharge applies?

We can tell you which families can fire on a lane and what measurement or address fact triggers each one. We cannot promise that a tariff published by someone else will not be amended while your cargo is in transit, and we do not quote amounts here. What we commit to is stating the trigger conditions in writing before collection is arranged, so a change in total is a known variable.

Why is collection from a supplier a separate charge?

Because it is a separate leg with its own cost drivers: distance to the factory, access at the loading point and waiting time at the dock. It is quoted per factory address rather than blended into freight, and is not free on any lane here. Consolidating several suppliers before arrival turns many collection events into one inbound movement, which makes supplier location a pricing decision.
