Five suppliers: consolidate or ship separately?

The fixed basket and destination

Assume five stock suppliers shipping to one China receiving warehouse, followed by delivery to a commercial address in Los Angeles, California. The same specifications, quantities and goods value are used for every option. The basket contains no batteries, liquids, powders or branded goods; actual acceptance and product obligations still need review.

All figures are USD. Product dimensions, transit days and supplier lead times are not being claimed. The carton dimensions below are assumed external packed sizes, and weights include the original carton and its contents.

• Supplier A: 100 plain cotton tote bags, goods $150; one carton 50 × 40 × 30 cm, gross 10 kg.
• Supplier B: 100 paper notebooks, goods $120; one carton 40 × 30 × 25 cm, gross 14 kg.
• Supplier C: 50 empty nesting polypropylene desk trays, goods $100; one carton 60 × 40 × 40 cm, gross 8 kg.
• Supplier D: 200 unbranded metal keyrings, goods $80; one carton 35 × 25 × 20 cm, gross 9 kg.
• Supplier E: 100 textile zip pouches, goods $100; one carton 45 × 35 × 30 cm, gross 6 kg.
• Goods total: $150 + $120 + $100 + $80 + $100 = $550. Original gross mass: 10 + 14 + 8 + 9 + 6 = 47 kg.

The illustrative charging rules

For this example only, the express-like rate is $8 per chargeable kg plus $18 per independently booked shipment. The economy-like rate is $6 per chargeable kg plus $18 per booking, with a later delivery window. Both hypothetical rates include fuel and final commercial-address delivery but exclude import charges. They are not named carrier services or market prices.

Assume each package is billed at the larger of actual and dimensional weight, then rounded up to the next 0.5 kg. Dimensional kg = centimetre length × width × height ÷ 5,000. DHL Express documents this dimensional divisor, but the rates and rounding here are invented. Confirm each real carrier’s basis, minimums and surcharges.

Option 1: five separate express-like shipments

• A: 50 × 40 × 30 ÷ 5,000 = 12 kg dimensional; max(10, 12) = 12 kg billed.
• B: 40 × 30 × 25 ÷ 5,000 = 6 kg dimensional; max(14, 6) = 14 kg billed.
• C: 60 × 40 × 40 ÷ 5,000 = 19.2 kg dimensional; rounded billable weight = 19.5 kg.
• D: 35 × 25 × 20 ÷ 5,000 = 3.5 kg dimensional; max(9, 3.5) = 9 kg billed.
• E: 45 × 35 × 30 ÷ 5,000 = 9.45 kg dimensional; rounded billable weight = 9.5 kg.
• Total billed weight: 12 + 14 + 19.5 + 9 + 9.5 = 64 kg. Freight: 64 × $8 + 5 × $18 = $602.

Option 2: repack into two cartons in one express-like booking

Assume a warehouse packing trial shows safe nesting and removal of unnecessary outer boxes is possible. The result is two cartons of 60 × 40 × 40 cm, at 25 kg and 24 kg gross. The combined 49 kg is 2 kg more than the original gross total because the replacement protection weighs more. This is an assumed packing outcome, not a promise that these goods will actually fit.

Each carton has 19.2 kg dimensional weight, so actual mass governs: 25 + 24 = 49 kg billed. Freight = 49 × $8 + $18 = $410. Add $25 repacking/materials + $15 consolidation = $450.

The original cartons total 0.25075 m³; the two assumed replacement cartons total 0.192 m³. Keep necessary protection and labels. A smaller volume is not worth damage, lost traceability or an oversize/heavy-piece surcharge.

Option 3: urgent keyrings separately, the rest by economy

Assume only Supplier D is needed earlier. Send its original 9 kg-billable carton on the express-like route: 9 × $8 + $18 = $90.

Assume the other four orders can safely use two economy cartons: 60 × 40 × 35 cm at 21 kg, and 60 × 40 × 30 cm at 19 kg. Dimensional weights are 16.8 kg and 14.4 kg, so billed weight is 21 + 19 = 40 kg. Freight = 40 × $6 + $18 = $258.

Total shipping/packing = $90 + $258 + $25 repacking + $15 consolidation = $388. This is $62 below the all-express consolidation option, but four suppliers’ goods arrive on the later assumed service. It solves a different timing requirement.

If none of the goods is urgent and the same two-carton pack is accepted on economy, 49 × $6 + $18 + $40 packing/handling = $352. Consolidating on a slower route can beat the split plan when the deadline permits.

Compare the complete basket, not freight alone

Common assumed charges: goods $550 + China freight $35 + buying service $25 + basic receiving/photos $15 + optional shipment insurance allowance $10 = $635. Assume no storage charge within the agreed receiving window. Insurance terms and any inspections beyond the stated scope still need a real quote.

Use an invented $120 import/entry allowance for every option solely to hold that variable constant. It is not a US duty rate or broker quote. Different entries may produce different real clearance fees; replace this line separately for each route before choosing.

Five separate express-like shipments: $635 + $602 + $120 = $1,357.

Two cartons, one express-like booking: $635 + $450 + $120 = $1,205. Difference from five separate shipments: $1,357 − $1,205 = $152.

Urgent D express-like plus the rest economy: $635 + $388 + $120 = $1,143.

All goods consolidated on economy: $635 + $352 + $120 = $1,107.

Hypothetical local offer for the same complete basket, including local delivery and applicable tax: $1,160. It is $45 below consolidated express and $197 below separate express, but $17 above the split plan and $53 above all-economy. Verify specification, available quantity and arrival date before treating the offers as substitutes.

Unknown damage, rejection, storage delay, examination, tariff changes and lost sales are not priced as zero-risk outcomes. No defect rate or delivery success rate is claimed; unresolved costs remain open before booking.

Get warehouse evidence before approving consolidation

• Order-to-carton reconciliation: each supplier order, SKU, quantity, parcel ID and arrival condition.
• The agreed photographs and checks, with sample count and any unopened goods identified. Photos cannot prove material, compliance or authenticity.
• Before-and-after external carton dimensions, scale readings, packing materials and an updated packing list. A listing weight is not a final freight measurement.
• Your approval to remove retail boxes or repack fragile items, preserving needed labels, traceability and protection.
• An itemised storage, repacking and consolidation charge, plus the final carrier remeasurement and surcharge rules.

When splitting wins, or the shipment should stop

A late supplier should not automatically hold an urgent order. Compare the added booking/entry charges with the actual deadline, without inventing a cost of delay. Separate routes may also be necessary for incompatible handling requirements.

Restricted products can change route acceptance for the mixed shipment. A battery, liquid, magnet or branded item needs its own review; do not hide it inside general cargo. Obtain written acceptance for the actual packing and destination. If no lawful, suitable route is available, do not dispatch.

Confirm the clearance and freight basis

For a duty-paid offer, identify the contracting seller, importer, tax/entry scope, named delivery place and exclusions. Compare sea only with its own weight/volume basis and all destination charges; the parcel arithmetic above is not an ocean-freight model.

Use your own basket for the decision

Enter the known amounts in the landed-cost calculator, keep unknowns visible, then send all supplier links, quantities, destination, required dates and packed measurements through the sourcing form. Request separate, consolidated and split quotations where appropriate.

Choose the accepted option that delivers usable goods when needed at the lowest supported total. There is no general saving percentage to apply before those quotes exist.
