* Trump extends tariffs exemption by 1 month for many allies
* Dollar supported by yield advantage, euro hurt by softer data

TOKYO, May 1 (Reuters) - U.S. stock futures pared small losses while Australian shares hit seven-week highs on Tuesday after the United States extended the deadline for its steel and aluminium tariffs to take effect.
Still, uncertainty over an expanding trade dispute between the United States and China as well as worries that Washington may abandon a 2015 international nuclear deal with Iran kept investors on edge.
S&P mini futures ESc1 ticked up 0.1 percent, erasing an earlier loss of 0.2 percent. Japan's Nikkei .N225 ticked down 0.1 percent while Australian shares .AXJO gained 0.6 percent, hitting their highest level since mid-March.
MSCI's dollar-denominated index of Asia-Pacific shares outside Japan .MIAPJ0000PUS was down 0.1 percent though only Australia and New Zealand are open. Many markets in Europe and Latin America will be closed on Tuesday as well.
U.S. shares lost steam late on Monday as worries about rising costs for companies kept investors on edge, despite solid corporate earnings and strong economic data.
Analysts expect S&P500 companies to report 24.6 percent growth in profits in the January-March quarter, according to Thomson Reuters data.
Yet rising U.S. bond yields and commodity prices pointed to higher costs down the road, with concerns about trade frictions and rising tension in the Middle East seen as potentially amplifying the cost challenge.
An earnings announcement due later on Tuesday from Apple AAPL.O , the world's largest company by market capitalisation, is attracting close attention, given speculation the sales of its flagship iPhone X have been sluggish.
"Earnings have been really strong so far. Microsoft (NASDAQ:MSFT) and Amazon (NASDAQ:AMZN) had a bumper quarter. The only concern has been Apple, which has been said to be lacklustre. Hopefully, unless they come up with downbeat guidance, the market may take it in stride," said Hirokazu Kabeya, chief global strategist at Daiwa Securities.
The market got a little relief when the United States decided to postpone the start date for steel and aluminium tariffs against the European Union, Canada and Mexico to June. United States also reached agreements in principle on tariffs with some other countries, including Australia and Brazil.
The news, first reported by the Wall Street Journal, lifted worries the exemptions would expire on Tuesday, easing investors' worst fears.
"Markets are kind of expecting the Trump way of negotiation to continue. So I do not think markets are overly concerned about them at this point," said Masahiro Ichikawa, senior strategist at Sumitomo Mitsui Asset Management.
In the currency market, the euro traded at $1.2078 EUR= , not far from 3 1/2-month low of $1.2055 touched on Friday, after weaker-than-expected German retail sales figures. the data is known to be volatile and is often revised, it added to recent signs that Germany's economy could be losing some momentum after last year's surprisingly strong growth.
The dollar has been supported against many other currencies thanks to the relative strength of U.S. economy and its yield advantage.
The Federal Reserve is expected to keep interest rates on hold at its two-day policy meeting starting later on Tuesday, with a June hike already priced in.
The British pound GBP=D4 stood at $1.3769, having hit a two-month low of $1.3715 on Monday, as recent data suggested a rate hike by the Bank of England this month, once almost seen as a certainty, could be delayed.
The dollar changed hands at 109.25 yen JPY= , near Friday's 2 1/2-month high of 109.54.
The Australian dollar stood at $0.7542, near Monday's 4 1/2-month low of $0.75255 ahead of policy announcement from the Australian central bank due later in the day.
Oil prices held firm near 3 1/2-year highs after Israeli Prime Minister Benjamin Netanyahu stepped up pressure on the United States to pull out of an international nuclear deal with Iran, presenting what he said was evidence of a secret Iranian nuclear weapons programme. intelligence experts and diplomats said he did not seem to have presented a "smoking gun" showing that Iran had violated the agreement and Iran dismissed Netanyahu's accusations, calling them propaganda.
But U.S. President Donald Trump, who has threatened to pull the United States out of the international deal unless it is renegotiated by May 12, repeated his criticism of the deal after Netanyahu's presentation, suggesting he backed the Israeli leader's remarks.
The White House said on Monday that the information provided by Israel on Iran's nuclear programme provides "new and compelling details". crude futures CLc1 traded up slightly at $68.72 per barrel, not far from last month's peak of $69.56, its highest level since late 2014.
Brent crude futures LCOc1 were $74.84 per barrel, near the 3 1/2-year high of $75.47 a barrel set last week.
