China LCL vs FCL Shipping: How Buyers Should Compare Options
Compare LCL and FCL for China shipments using confirmed cargo dimensions, total quoted charges, handling, schedules, delivery needs and destination…
Shipping preparation
Calculate carton CBM, separate gross and volumetric weight, and prepare a clear packing-data request before comparing shipping quotes for goods from China.
A low unit price can lose its appeal when the packed goods take up more space than expected. Before comparing shipping options from China, ask for the finished carton dimensions, carton count and gross weight. Those three facts give a forwarder a much better starting point than a product link alone. This guide explains the calculations with a worked example and shows which packing details still need confirmation.

Ask the supplier for the outside dimensions of the closed, finished shipping carton. Product dimensions, retail-box dimensions and master-carton dimensions describe different things. A storage basket might be small on a product page but require inserts, a retail box and an outer carton. Define your packaging requirements before using a catalogue dimension in a shipping calculation.
Record the units explicitly: centimetres for dimensions and kilograms for weight are convenient for a shared packing sheet. Ask whether measurements are estimated, measured from a packed sample, or taken from the completed batch. If there are several carton sizes, give each size its own row. Do not multiply the largest carton size by every carton unless you deliberately want a conservative estimate.
CBM means cubic metres. For a rectangular carton measured in centimetres, calculate length × width × height ÷ 1,000,000. A carton measuring 60 × 40 × 35 cm occupies 0.084 m³. Twenty identical cartons occupy 1.68 m³ before any additional pallet, crate or consolidation packaging. These are illustrative dimensions, not a shipping quote.
For a mixed shipment, calculate the volume for each carton type, multiply by its count, then add the results. For example, ten cartons of 0.084 m³ plus five cartons of 0.060 m³ total 1.14 m³. Keep the original dimensions in the sheet so another person can check the calculation. Round only when presenting the total; let the selected provider explain its own billing-rounding rules.
Net weight usually describes the goods without their packaging; confirm exactly what the supplier includes. Gross weight includes the packed contents and packaging for the unit being weighed. Volumetric weight converts package volume into a weight used for a service's pricing calculation. CBM and kilograms are different measurements: 1.68 m³ does not tell you the shipment's actual weight.
DHL Express's published UK guidance uses centimetres multiplied together and divided by 5,000, with the greater of actual and volumetric weight used for charging. At that divisor, the 60 × 40 × 35 cm example is 16.8 kg volumetric weight. If its gross weight is 12 kg, the volumetric figure is higher. Confirm the applicable service, divisor and rounding when comparing supplier quotes or forwarder quotations; this example is not a universal rule for air, sea, road or express freight.
Changing the units per carton can change both the number of cartons and the outside dimensions. Nesting products, adding dividers or switching to a stronger carton can alter the result. A smaller box is only useful if it still provides suitable protection and meets the agreed packing needs. Request a revised packing sheet whenever the packaging proposal changes materially.
If you are consolidating products from several suppliers, ask who will remeasure the combined shipment and when. An added pallet or crate can change the final dimensions, weight and handling conditions. For palletised cargo, request the complete loaded dimensions including the pallet and any overhang, plus gross weight and whether stacking is allowed. Avoid treating a sum of loose-carton volumes as the final pallet volume.
A useful message is: 'For the selected product and quantity, please confirm units per carton, carton count, outside carton dimensions in cm, and gross kg per carton. Please separate different carton sizes and identify whether the figures are estimated or measured. If pallets or crates are included, send the complete packed dimensions and gross weight. Please also confirm the packing version and expected ready date.'
Ask for photographs of the packed carton, its markings and the measurement where an inconsistency matters. A photo supports the record but does not replace a measurement or quality inspection. Use the shipping handover checklist to agree who checks the final carton count and shipping data before collection. If final measurements differ from an estimate, obtain an updated quote before approving the next step.
Give each provider the same packing sheet, pickup location, destination and service requirements. Ask which charges the quote includes, its validity, the pricing unit and any assumptions about collection, delivery, customs handling or additional packaging. Volume and weight alone cannot produce a reliable landed cost. A quote based on estimated cartons should remain labelled as an estimate until the relevant data is confirmed.
Include available packing information in the notes of your sourcing request alongside the product link, specification, quantity and destination. You can start with missing measurements marked 'to confirm' and ask for a packing-data review.
