Freight consolidation changes the answer to warranty and after sales at container scale, which is why small and large buyers reach different conclusions.
Why warranty and after sales matters on the Box 4
A clear dead on arrival policy removes friction for retail partners.
Where two suppliers look identical on price, warranty and after sales is usually the variable that separates them over a full year.
Spare parts availability matters more than warranty length in practice.
