UK GVT, OTSI issued guidance to support businesses in tailoring due diligence within exporter contracts and support those wishing to insert a no re-export to Russia clause.
Guidance is for those involved in export and making available of common high priority items and other items critical to Russian weapons systems and military development.
Contractual clauses prohibiting buyers/importers from re-export, or export from a third country, of items subject to Russia sanctions could help protect you as a seller.
While UK GVT does not require it, including such clauses in export documents could help mitigate risk of being inadvertently involved in a customer's breach of sanctions.
