China is beefing up safety checks on mail and parcels to addresses in Beijing to ensure security of the National Day celebrations on Oct. 1, the Ministry of Public Security (MPS) said Tuesday.

China will impose interim regulations on postal and delivery services to Beijing from Sept. 15 to Oct. 8, said a circular jointly issued by six administrative bodies including the MPS, the Ministry of Transport, and the State Post Bureau.

During that time, transport and logistics companies, freight and passenger transport stations, and international freight forwarders should check each item sent to Beijing and record the ID number of the delivery service, the MPS said on its website.

Postal and express mail service providers should carefully check the name of mailed items, as well as the names and ID numbers of the consignors and addressees to prevent carriage of banned materials, the MPS said.

Materials banned from mail services include items such as weapons and ammunition, explosives, flammable and corrosive materials, poison, narcotics, biochemical products and infectious goods.

Customers who refuse inspection will not be provided with delivery service.

Liquid chemicals, gases, liquids and powders not able to be recognized will also not be accepted for mailing.

China will hold a series of activities in Beijing, including a military parade and pageant, to mark the 60th founding anniversary of the People's Republic of China on Oct. 1.
