On 19 March 2021 the FSC International Board of Directors decided to postpone the effective date of FSC-STD-40-004 V3-1 Chain of Custody Certification until 1 September 2021.
Simultaneously, the end of the transition period has been extended from 12 months to 15 months after the effective date. This means the transition period for version 3-1 of the standard spans from 1 September 2021 to 31 December 2022.
Additionally, some minor typos have been corrected.
You can find the new version (FSC-STD-40-004 V3.1) of the standard here.
