For a bulk-buying business, a rejected or damaged unit should not automatically be folded into a per-usable-unit landed-cost figure. Its cost should remain visible in a separate reconciliation until the unit’s condition and treatment are confirmed. The American Society for Quality defines scrap as defective product or material that cannot be repaired, used, or sold, while the cited IAS 2 wording excludes abnormal amounts of wasted materials from inventory cost. These definitions address different questions and do not, on their own, classify every rejected or damaged unit in the same way.
Separate the shipment total from the usable-unit view
The International Trade Administration defines landed cost as “the total price of a product once it has arrived at the buyer’s doorstep.” That provides a shipment-level measure. It does not, by itself, explain how to allocate a unit later identified as rejected or damaged.
A worksheet can keep the following items separate:
- The total delivered price for the shipment.
- The quantity that remains usable for its intended purpose.
- The quantity rejected or damaged.
- The documented condition of each affected unit.
- Costs that can be assigned to each group without guesswork.
- Any adjustment that is actually documented.
When the objective is cost per usable unit, the quantity ordered or invoiced should not automatically be used as the denominator. The calculation should distinguish the units still available for use from the affected units awaiting classification or settlement.
Test the condition before assigning a category
“Rejected” and “damaged” describe an event or decision; they do not by themselves establish scrap. Under the cited definition, a unit must be defective product or material that cannot be repaired, used, or sold. If it can still be repaired, used, or sold, the label “rejected” or “damaged” alone does not meet that definition.
IAS 2 addresses a different question: whether there is an abnormal amount of wasted materials. The cited wording does not provide a threshold for deciding when waste is abnormal, and it does not say that every rejected or damaged unit is abnormal waste. That assessment must be made separately for the affected goods and the applicable accounting treatment.
Keep unresolved amounts out of hidden per-unit math
A neutral working expression is:
Usable-unit cost = costs assigned to usable units ÷ usable units
This is an analytical convention, not a quotation of an accounting standard. The cited wording does not specify how shared costs should be allocated. A business should therefore state its allocation basis rather than embed an unresolved amount invisibly in a single per-unit figure.
The rejected or damaged amount should remain separately identifiable. If a refund, credit, replacement, or other adjustment is anticipated, it should not be netted against the usable-unit figure until the governing documents establish it. The cited definitions do not establish that any particular refund, credit, or replacement is due.
What still needs confirmation
Before a final figure is relied upon, the relevant records should establish:
- Whether each affected unit meets the cited scrap condition.
- Whether any waste is abnormal for the IAS 2 assessment.
- How costs are allocated between usable and affected units.
- Whether a documented commercial or accounting adjustment applies.
- Which accounting policy governs the reported treatment.
The cited definitions do not determine who bears the cost of a rejected or damaged unit, whether a supplier must refund or replace it, or what evidence or timing rule applies. Those points cannot be inferred from the landed-cost definition. They should be checked against the applicable contract, invoice, delivery records, and accounting policy, with professional accounting advice when financial reporting is affected. Until those points are confirmed, the affected units and unresolved amounts should remain visible rather than being absorbed into an apparently precise usable-unit cost.
