Director of Da Nang city’s museum Huynh Dinh Quoc Thien confirmed the recognition, saying the certificates will be presented to the city later this year.
Thien said the nomination would help preserve the trade of Nam O in the suburban area of Da Nang, which has existed for more than four centuries.
He said local residents still earn an income from fishing and fish sauce despite rapid urbanisation.
Situated at the foot of the Hai Van Pass, 17km northwest of downtown Da Nang city, Nam O village has produced fish sauce since the 19th century, and the trade still earns villagers their livelihoods.
Tran Ngoc Vinh, 71, chairman of the Nam O Fish Sauce Trade Association, said more than 110 households in the village produce fish sauce using traditional techniques and materials – anchovies and salt – with harvest season between March and July.
He said anchovies are fermented with salt in terracotta or jackfruit-wood jars for 12 months.
The village used 200 tonnes of anchovies to produce 125,000 litres of fish sauce last year.
The 500-year-old pottery trade in Thanh Ha Village, on the outskirts of Hoi An, was also named as a national intangible heritage.
The trade emerged in the ancient town in the late 15th century, and some villagers still make items using brick kilns.
The pottery craft was one of the oldest trades that still remains in the UNESCO-recognised world heritage site Hoi An.
The trade is introduced as a craft experience for tourists rather than for mass production as in previous decades.
Pottery products from Thanh Ha were major commodities exchanged with businessmen from Japan, China and Europe in the 17th century.
The village – a popular destination on Hoi An’s tourism map – hosts around 100 tourists each day.
An exhibition centre – the Thanh Ha Terracotta Park – was built to introduce the old trade and pottery experience to tourists.
