The US Food and Drug Administration (FDA) has extended by six months its deadline for submitting details of e-cigarette ingredients.
Larger manufacturers now have until 8th May 2018 to deliver their ingredient listing submissions for products which were on the market on 8th August 2016, while smaller-scale manufacturers have an additional six months until 8th November 2018.
The deadline for larger manufacturers had originally fallen this week.
For e-cigarettes introduced to the market since 8th August 2016, the situation is unchanged: ingredients listings must still be submitted at least 90 days before the product goes on sale.
The FDA cited problems with its eSubmitter software in announcing the extension, but it is the latest of several which it has granted to the e-cig industry.
Most notably, the deadline for premarket tobacco product applications (PMTAs) was pushed back by nearly four years.
The product registration deadline was also extended by about two weeks, and further relief on deadlines was given to companies affected by natural disasters.
