The Supreme Court in India has ordered federal and state governments to regulate the sale of acid in an attempt to reduce attacks on women.
The court said that acid should be sold only to persons with valid identity cards and sales will have to be reported to the police.
Buyers will also have explain why they need the chemical and sales will have to be reported to the police.
Also more compensation will be paid: at least 300,000 rupees (£3320). There are an estimated 1000 acid attacks per year in India.
The BBC reports the targets are mainly women and are often targeted by jealous partners.
The Supreme Court ordered on Thursday that acid should be not be sold to anyone under the age of 18. It also ruled that no bail should be allowed for the offence.
The Indian government has been accused of being too slow to deal with the issue of acid attacks.
Earlier this month, the Supreme Court strongly criticised the government for failing to formulate a policy to reduce such attacks.
It wants to see these new measures enforced within the next three months.
