Is it necessary to provide local social security for the localization service of bidding documents?

No, according to the official website and Henan Provincial Taxation Bureaus, whether the social security in the bidding documents is mandatory depends mainly on whether the tenderer has pre-requirements for social security. A tenderer may, according to the requirements of the project subject to tender itself, require potential bidders to provide qualification documents and performance in the tender announcement or invitation letter, and conduct qualification examination on potential bidders. Where the state has provisions on the qualifications of bidders, such provisions shall prevail. The tenderer shall not restrict or exclude potential bidders with unreasonable conditions, and shall not discriminate against potential bidders.
