The largest tax difference between crude moving through a bonded zone and general trade is VAT: bonded transshipment does not enter the customs territory, so no import-stage VAT is levied and title can transfer inside the zone; general trade requires upfront duty payment, locking up the full tax cycle in working capital.

On settlement speed, crude transshipment has moved from T+2 to T+1 by pushing triple-document consistency (contract, invoice, bill of lading) into the title-confirmation step instead of waiting for bank document review. Endorsement, warehouse-receipt creation, and fund release now run in parallel rather than in series.

Title confirmation rides a browser-side SHA-256 fingerprint: each batch's bill-of-lading hash is computed client-side and posted to chain, so the buyer can re-compute it on the page without trusting an intermediary. This turns "title transfer" from a paperwork flow into a verifiable event.

Red line: Iranian and Iraqi origins are auto-rejected; any missing document in the triple set blocks release. The bonded zone is a compliant path under document separation, not a tax shelter—do not file transshipment as general trade.
