Exporters are scrambling under the sudden imposition of Donald Trump's tariffs. 

The President's signature economic policy has taken effect, with US allies and adversaries all facing tariffs. 

New Zealand's been hit with the lowest rate -10 percent.

Egmont Honey founder James Annabell says the move prompted hasty discussions with US-based buyers.

He explained Costco US knew his company couldn't afford to take on the extra cost - so now it's likely US consumers will bear the brunt of it.
