U.S. trade officials are signaling a tougher stance on tariffs, with indications that some duties could rise above the previously discussed 15% level.According to remarks reported by Jin10, Office of the United States Trade Representative Greer said the U.S. will initiate a formal investigation into Indonesia over tariff-related issues. The probe will assess Indonesia’s current trade practices and compare them against measures the country had previously committed to implement.Greer noted that the findings of the investigation would inform a final ruling, adding that the outcome could result in tariffs exceeding 15% in certain cases. While no specific timeline or tariff schedule was disclosed, the comments suggest that the U.S. is prepared to escalate trade measures if compliance gaps are identified.
