No You've confused. Dumping is if you sell a product for less than what you charge in your home country.
Gatzz...your $ 100 and $112.5 example is wrong. In fact this is the whole idea behind importing somethng from abroad. That if you can't make it cheaper domestically, import it from where it is produced cheaply. This has to do with comparative advanatage and competitivness in producing something. Please see the link for furhter clarification on dumping...
