The more immediate impact will be on exports from Afghanistan to India. The trade value between the two countries had reached close to $1 billion in FY25, after recovering from Afghanistan's civil war and the impact of Covid-19. All those have to be routed through sea routes, since India has also closed its Attari-Wagah checkpost. Afghanistan exports dried figs, asafoetida and its seeds, saffron, raisins, cumin, and almonds. Imports from India are value-added products like sugar, industrial materials, automobile parts, cotton products and a host of machinery items.
However, given the shipping ban, which uses powers under the Merchant Shipping Act, vessels with the Pakistan flag cannot enter Indian ports. This means that while port officials do not have any role in identifying the origin of the consignments, they still need to be careful. The onus of identifying goods from Pakistan rests squarely with the Customs officials, which is why their numbers on active duty have been enhanced.
