New Delhi, Sept. 29 -- Indian drugmakers have received some relief from the latest US tariff measures. Washington will spare certain speciality medicines and their ingredients from a new 100 per cent tariff on patented drugs. The exemption covers treatments for rare diseases, infertility, cancer and other specialised conditions.

The exemption covers medicines used to treat rare diseases and several specialised therapies, including infertility treatments, cell and gene therapies and antibody-drug conjugates. The same zero-tariff treatment will apply to qualifying ingredients used in these products.

The US Commerce Department listed India among 20 countries eligible for the exemption in a notice published in the Federal Register.
