If there is an update needed for labels (i.e. name of company, address, phone # etc.) how long of a grace period will Health Authorities (HA) allow a sponsor company to use the old labels before the updated ones need to be made effective. Understanding there might be a difference in grace period depending on the country itself and HA regulations, is there an average standard depending on the region (i.e. US, EU, UK, Latin America, APAC etc.).
