Reporter THE LEGAL representatives of industry groups affected by safeguard duties on car imports are questioning the validity of the petition for the protection measure filed by a labor group. The Department of Trade and Industry (DTI) applied safeguard duties after it confirmed the Philippine Metalworkers Alliance’s (PMA) claim that employment in the industry sank after imports spiked. The Safeguard Measures Act or Republic Act No. 8800 allows domestic producers to ask the government to conduct an investigation into their import competitors if they claim to have been injured by excessive imports. “PMA is a national union of automotive, iron, and steel workers in electronics and electrical sectors. They do not represent the domestic industry,” Rodolf C. Britanico, the legal representative of the China Chamber of Commerce for Imports and Export of Machinery and Electronic Products, said at a conference with the Tariff Commission on Wednesday.
