EXPLANATORY NOTE 
The Constitution, Article XII, Section 12, provides “The State shall promote the 
preferential use of Filipino labor, domestic materials, and locally produced goods, and adopt 
measures that help make them competitive.” 
For Government must promise and encourage the use of Philippine made products, 
materials and supplies in every contract for the construction, alteration, or repair of any public 
building or public work. 
This bill seeks to achieve such goal by blacklisting contractors, subcontractors, and 
materialmen and suppliers who fail to comply with such requirement.* 
* This bill was originally filed during the Thirteenth Congress, First Regular Session.
