Trade experts warn of US tariff risks to NZ exports

Two leading New Zealand trade experts warn that the 15% tariff slapped by the US shouldn't be taken lightly.

The tariff could go higher and be hugely disruptive to the agriculture sector, NZ's main export earner.

Former Trade Minister and trade negotiator Tim Grosser says the 15% tariff imposed on NZ is a floor price, not a ceiling, and there's a possibility further tariffs could be added in future.

He says it's still uncertain whether the 15% tariff announced by US President Donald Trump includes the existing tariffs imposed on NZ exports to the US that were negotiated about 30 years ago, or is on top of these.

"NZ is not out of the woods yet and there is a high degree of uncertainty surrounding the announcement by Donald Trump as no details have been provided," he told Rural News.

Grosser says it's important to not just focus on the 15% tariff, but to look globally at the wider impacts for NZ of varying tariff rates being applied to other countries - something he calls a "crude piece of economic nonsense".

He says the impacts of the tariffs will cause chaos ion some of the economies that are extremely important trading partners with us.

He says over the years NZ has developed new markets in countries which 20 years ago as a trade negotiator he would never have thought about.

Grosser points to the example of Vietnam - now NZ's second largest market for apples. He says the growth rate of Vietnam has been phenomenal but now that Trump has forced that country to accept a tariff rate of 19%, the future for NZ sales there could be endangered.

He adds that some of the farm lobby groups in the US may try to pressure Trump to take a harder line against exporting countries like us.

"What I'm saying is that we can't assume that the very steady export growth and progress in diversifying our agricultural exports is going to proceed in the next five years as it did in the last 20 years," he says.

Grosser also notes that the 15% tariff rate imposed on NZ is 5% higher than Australia, which has a free trade deal with the US, and that could widen the gap between the trans-Tasman nations.

Former special agricultural trade envoy Mike Petersen believes the 15% tariff is going to be hugely disruptive for the NZ agri sector, although he adds, amongst the chaos there may be opportunities. He says what concerns him most is that now that the 15% tariff has been imposed, there is every chance that even if a new administration takes office in the USA, these will not be removed and could be there for years, possibly decades, to come.

Petersen says that the way this is playing out, NZ could find itself at a disadvantage to the likes of Australia, Argentina and Uruguay.

"The other frustrating thing is that the decision was made about NZ without us being able to have any real input into that," he told Rural News.

Both Petersen and Grosser are concerned about the effects of high tariffs imposed on a country such as Brazil - a major exporter of beef to the US.

Petersen says their high tariff rate effectively cuts them out of the US market and that raises the question of where all that meat will end up. Some say China, but the word is that China is already investigating the level of its beef imports.

"So right now no one knows what is happening and no one fully understands the implications of the US tariff policy," he says.

Trade Minister Todd McClay says the tariffs risk harming exporters and consumers of both countries.

McClay is seeking an audience with US Trade Representative to make New Zealand's position clear.

"The US currently faces an average tariff of just 0.8% when exporting to New Zealand, far lower than what we face into their market," McClay says.

Editorial: Hope for the best

New Zealand's dairy industry is right to call out Donald Trump over the damage the additional 15% tariff the US is imposing on our exports but also imposition on lower tariffs on our competitors.

Editorial: We are Trumped

OPINION: Nothing it seems can be done in the short term to get Donald Trump to change his mind about removing the unfair 15% tariffs that he’s imposed on New Zealand exports to the US.
