Indian parent places 2 separate POs on USA based wholly owned subsidiary for supply material plus commissioning by foreign technician. By mistake one consolidated invoice is sent and with pending commissioning, both values are declared and customs duty paid. Actually, commissioning is sub to withholding tax..should one integrate both as without installation, is useless.what is correct route and what to do now, assuming, commissioning is pending even after 2 years from supply.
