* Heavy rains, cyclone and floods destroy crops in Bangladesh

* Vietnamese rates edge up on low supply

* Muted demand weighs on Thai prices

Sept 10 (Reuters) - Rice export prices in top hub India rose to their highest in nearly 18 months this week as supplies remained constrained due to pandemic-induced disruptions, while Bangladesh may have to import the staple after natural calamities damaged crops.

India's 5% broken parboiled rice prices RI-INBKN5-P1 climbed to $387-$394 per tonne from last week's $384-$390.

With the top exporter now behind only the United States in the tally of COVID-19 cases, exporters have been grappling with limited availability of containers and mill workers at its biggest rice handling port of Kakinada on the east coast.

“Coronavirus outbreak has affected rice milling in Andhra Pradesh and loading operations at Kakinada. Limited supplies are available for exports though demand is robust,” said a Kakinada-based exporter.

In neighboring Bangladesh, domestic prices have risen up to 20% over a month amid fears of a production shortfall.

Excessive rainfall in March-April, cyclone Amphan in May and three spells of floods in June-July damaged most crops, of which 70% was paddy, according to agricultural ministry officials.

Bangladesh needs to start importing rice without any delay, sources familiar with the matter said.

In Vietnam too, low domestic supplies pushed prices for 5% broken rice RI-VNBKN5-P1 to $490-$495 a tonne on Thursday from $490 last week.

“Domestic supplies are very low at the moment, while some exporters continue to fulfill their contracts signed earlier with customers from Malaysia, Timor-Leste and Africa,” a trader in the Mekong Delta province of Tien Giang said.

Traders expect prices to come down in the coming weeks ahead of the autumn-winter harvest.

Adding to demand woes, another trader said the Philippines could suspend rice purchases at least until November to support domestic prices of an ongoing harvest there.

In Thailand, benchmark 5% broken rice RI-THBKN5-P1 prices eased to $487-510 per tonne on Thursday from $500-$513 last week amid muted demand.
