The Hidden Cost of a Power Bank SKU: Testing, Packaging, Freight and Return Exposure
Why can the lowest factory unit quote become the more expensive power bank launch?
Compare complete, scenario-based landed cost per sellable unit rather than the quoted factory price alone. Add development and test amortization, packaging and labeling, freight, duties and taxes where applicable, channel fees, expected damage and return handling, and the cost of unsold stock. Use buyer-supplied quotes and explicit assumptions. A cheaper unit may lose its advantage if it needs extra tooling, heavier packaging or higher recovery spending.
Decision framework for buyers and importers
1. Fix a comparable basis
Use identical SKU specifications, quantity, incoterm, currency, destination, test scope, packing format and warranty assumptions. If one quote excludes artwork, lab work or freight, add those lines.
2. Build a transparent model
Landed cost per sellable unit equals (purchased quantity × factory unit price + one-time costs + packaging + freight + nonrecoverable duty/tax + channel costs + expected returns and storage) divided by expected saleable units. Keep ranges for uncertain inputs and show each input source.
3. Stress-test the choice
Run base, high-freight and high-return scenarios. Show cash tied in MOQ and slow-moving stock separately. Approve only when the buyer sees which assumption changes the ranking and who owns each cost.
| Cost line | Input source | Allocation | Sensitivity |
|---|---|---|---|
| Factory unit and tooling | Signed quote | Per unit / program volume | MOQ and revision |
| Testing and artwork | Lab and agency quote | Expected launch volume | Retest after change |
| Packaging, freight, duty | Forwarder/customs quote | Shipped sellable unit | Weight, route, market |
| Returns and aged stock | Channel history or scenario | Expected saleable unit | Damage and demand |
This original decision table is a working aid. Apply it to the exact SKU, market and signed agreement.
Evidence file, warning signals and scenario
Evidence checklist
- Comparable SKU and incoterm in each quote.
- Tooling, test and artwork scope with owners.
- Pack dimensions, freight mode and destination.
- Channel fee and return assumptions.
- Base and stress-case model with source quotes.
Hypothetical buyer scenario
Illustrative, not a price quote: Supplier A has a lower unit price but needs a new mold, extra pack reinforcement and a larger minimum order. Supplier B has a higher unit price with existing tooling and a smaller minimum. The buyer enters actual quotations and channel forecasts into one model. The ranking changes only when the total scenario cost changes.

Frequently asked questions
What is the simplest formula?
Total relevant launch and fulfillment cost divided by expected saleable units.
Should refundable VAT count as a cost?
Treat taxes according to actual recoverability and accounting rules.
How are one-time tests allocated?
Across a stated volume, with a stress case if sales are lower.
What if freight is unknown?
Use a range from current forwarder quotes and update before approval.
Do returns belong in the model?
Yes, with clear buyer and supplier recovery assumptions.
Can different specs be compared?
Normalize the specification or clearly price the differences.
Is the cheapest landed unit always best?
Also consider cash exposure, reliability, channel fit and timing.
