The original purpose of QCOs was to ensure quality standards to protect consumers, improve product quality, and keep substandard imports out of the Indian market. Over time, however, the policy expanded far beyond these objectives. From covering around 100 products in 2014, QCOs now extend to well over 650 product categories. Besides, they no longer apply only to finished consumer goods. Raw materials, industrial components, intermediates, and machinery have increasingly come within their ambit, affecting manufacturing supply chains. The economic costs of the regime are mounting. Manufacturers dependent on imported inputs have found themselves unable to source components because overseas suppliers first need certification from the BIS. The approval process is often slow, expensive and uncertain. The burden falls disproportionately on micro, small and medium enterprises, which lack the leverage to persuade foreign suppliers to obtain Indian certification or the resources to withstand prolonged delays. Far from making Indian manufacturing more competitive, the regime has made it harder for domestic firms to integrate with global value chains. QCOs are often seen as a non-tariff barrier on imports.
