Trade credit extension allows five-year finance for infrastructure capital imports, with relaxed initial contracting for existing credits. Trade credit for infrastructure-sector companies is permitted up to five years for imports of capital goods (DGFT classified), provided the credit is contracted ab initio for the prescribed minimum period and AD Category I banks do not issue LC/guarantees/LoU/LoC for the extended period beyond three years; existing trade credits benefit from a temporary relaxation reducing the abinitio contracting minimum from fifteen months to six months, while the fifteen month requirement continues for future credits.
