The prices of non-woven fabric, the most common material used in festive ornaments and dolls, soared from about 8,000 yuan a ton in January to more than 16,000 yuan a ton in October.

"With raw materials making up at least 40 percent of our gross costs, I dare not purchase any non-woven fabric right now. I'm waiting for the price to drop," says Huang, whose company has been producing yuletide ornaments for 18 years.

Yihua Hardware Handicraft Co in Dongguan earned about 10 percent profit from a Christmas tree last year but almost no profit this year, says the head of the company surnamed Chen, reported the Dongguan Daily.

The price of polypropylene fiber, which is used to stuff many toys, has grown by about 20 percent so far this year, according to Taibai Fiber Co in Guangzhou.

The cotton price had climbed from about 18,000 yuan to 28,500 yuan per ton by mid-November since Sept 1, according to the statistics posted on industry website Cottonchina.org.

Many traders are now looking to buy from manufacturers in East China's Zhejiang province, where supplies are cheaper.

"We're now less competitive, as Shantou is not a source of raw materials," complains Chen Shaoyan, owner of Zheng Chang Long Carton Factory, which has been making yuletide ornaments for 10 years.

However, even in Zhejiang, the so-called "home of fabrics", plants have witnessed staggering price hikes for core material in their products.

"Our gross costs have increased by about 25 percent," says Huang Jili, general manager of Orient Crafts in Ningbo, a city on the province's east coast. "We are feeling the same pressures."

Although the price of raw materials is likely to fall, analysts predict companies will have to deal with labor shortages and rising salary demands for some time to come.

Factories across the Yangtze River and Pearl River deltas - China's two economic powerhouses - have been short on hands since March this year, following the national Spring Festival holidays.

In response, at least 14 provinces and municipalities have raised the minimum wage, including both Guangdong and Zhejiang.

"If my production line is running at a full capability, we need at least 800 workers," says Chen in Shantou. "This year, I had only 200 workers during the peak time."

He says the situation forced his company to reject several orders from clients, resulting in sales falling 30 percent.

"Some manufacturers finished the orders at a loss to maintain the operation and keep their workers," adds Chen.

Luo Yonghuang, deputy general manager of Hongfeng Arts and Crafts in Meizhou, Guangdong, complains that even though he raised his workers' wages by 150 percent, the company still experienced a labor shortage.

As most Christmas products are assembled by hand, the industry is extremely reliant on human resources, and a shift toward mechanized operations would be economically unfeasible for most.
