* Spot iron ore down for 6th straight day
* Dalian iron ore futures fall 1.6 pct
* Shanghai rebar hits fresh record low

MANILA, Oct 21 (Reuters) - Spot iron ore fell to its lowest level since July on Wednesday, pressured by weak steel demand in top consumer China that has dragged Shanghai rebar futures to a record low and forced steel producers to limit inventories of the raw material.
Iron ore has fallen nearly 27 percent this year, on track for a third straight annual decline, as low-cost suppliers boost production at a time when Chinese steel demand is waning.
BHP Billiton BHP.AX BLT.L , the world's No. 3 iron ore miner, lifted September quarter output by 7 percent and stuck to its full-year target to raise production by 6 percent to 247 million tonnes. urn:newsml:reuters.com:*:nL3N12K5L1
Benchmark 62-percent grade iron ore for delivery to China's Tianjin port .IO62-CNI=SI fell 0.8 percent to $52.10 a tonne on Tuesday, according to The Steel Index.
That was its lowest since July 27, stretching its losing run to a sixth consecutive day.
"I think we'll see some fairly twitchy moves and it could get worse over the next three to six months, but after that it's probably going to try to find some traction just above $50," said Vishnu Varathan, senior economist at Mizuho Bank in Singapore.
Varathan sees a recovery in iron ore prices towards the third quarter of 2016 as most of China's infrastructure projects get underway, but said there might be a lag between the capacity of these projects to absorb the growing low-cost supply.
Potentially adding to the glut, Indian miner Vedanta Ltd VDAN.NS expects to export more than 5.5 million tonnes of iron ore from the state of Goa, most of which should find its way to China. urn:newsml:reuters.com:*:nL3N12K2JC
Near term, the weakness is likely to continue with no recovery in sight for steel prices amid a slowing Chinese economy and chronic overcapacity that has spurred many producers to sell more steel overseas and keep their iron ore inventories at a minimum.
Rebar, a steel product used in construction, fell as far as 1,788 yuan ($282) a tonne on the Shanghai Futures Exchange SRBcv1 on Wednesday. It was the lowest for a most-traded contract since the exchange launched rebar futures in 2009.
On the Dalian Commodity Exchange, January iron ore DCIOcv1 was down 1.6 percent at 366 yuan a tonne by 0321 GMT, suggesting further weakness in spot prices.
