Southern China's Guangzhou City is seeing high level of international passenger and freight traffic as the ongoing annual Canton Fair attracts hundreds of thousands of exhibitors and buyers from across the world. 

The 138th edition of the China Import and Export Fair, or Canton Fair, is taking place in Guangzhou from Oct 15 to Nov 4, gathering about 32,000 exhibitors and 240,000 buyers. 

Data from Guangzhou Customs showed that ports in Guangzhou handled about 5,200 inbound flights and 800,000 passenger entries in this October, marking the year-on-year of growth of 9.2 percent and 14.8 percent, respectively. 

The growing number of travelers has spurred rapid growth of tax refund business for departing passengers in Guangzhou. 
The local authorities have set up the green channel for travelers' tax refunds and intensified data connectivity between customs and tax refund agencies to improve processing efficiency for travelers.

"We have implemented a convenient supervision model of 'one form for one package'. That means each tax refund application form corresponds to a sealed package. As long as the packaging is intact, customs can quickly verify the tax refund items, improving the efficiency of customs verification procedures by about 70 percent," said Zhang Xiaojuan, deputy director of postal supervision department of Guangzhou Customs. 

In October alone, Guangzhou Customs had supervised 72,000 tons of air cargo import and export goods at Guangzhou ports, an increase of 5.3 percent year-on-year, according to Zhang. 

To meet the export demand for goods ordered from the Canton Fair, the customs at Guangzhou Baiyun International Airport has implemented a 24-hour smart customs clearance for air export goods, enabling the procedures to be finished within one day.
