The license duration of water pipe installation contractors is 5 years, but the contractors can make an extension registration and renew the business permit from the municipal or county (city) authority-in-charge 3 months before the deadline date of the license. If the contractors fail to make an extension or meet the condition for extension, the origin permit would be ineffective after the deadline date. The extension appliers should submit the last tax payment evidential documents and the original business permit. The extension range each application is 5 years.
