Amendment of postal rates and mail carriage

The Director of Posts is responsible for ensuring mail carriage between post offices within the Philippines, and between the Philippines, the United States, and foreign countries, either by contract or other means.
Contracts for air mail transportation may be entered into by the Secretary of Commerce and Communications, with Governor-General approval, for terms not exceeding five years.
Payment for air mail services may be based on fixed rates per kilogram or per kilometer, or by equivalent additional postal rates collected.
Contracts must be awarded to bidders who are the most advantageous to the government and properly qualified and equipped to provide satisfactory service.
The contracts aim to promote efficient commercial aviation services accessible to the public.
Contract awardees are authorized to use government-controlled navigation facilities and landing fields free of charge for mail transportation purposes.
The Secretary of Commerce and Communications, with Governor-General approval, may issue rules and regulations necessary to implement the air mail transportation provisions.
