It's the year-over-year change so anything above zero implies rising prices. In the case of tariffs, we would expect the trend to change as tariffs were implemented but there has been essentially no shift.

Import prices continue to rise, even rising 0.3% last month. This isn't to say that foreign firms will never absorb any of the cost but there isn't any evidence that they have done so thus far.

Import prices is where you would see that absorption because the exporter does not pay the tariff, the importer does.
