The circular from the Ministry of Commerce and 19 other agencies, pushing trade liberalization in the Hainan free trade port, opened a gap for the Yangpu bonded port zone: crude and product oil moving across the first line are exempt from enterprise-qualification and volume controls. In operator terms, crude or product resale, storage and transshipment inside the Yangpu fenced zone no longer falls under the non-state import allowance — that 257-million-tonne national pool with its two-year performance threshold — and no longer requires the terminal, tankage and track-record criteria to qualify as an importer.

For SNSUC this adds one more structure to the resale book. Beyond the standing path — sign the SOMO contract at the offshore SPV (Singapore or Hong Kong) and let the Chinese refiner clear customs on its own allowance — there is now a zone entity plus bonded warehouse option: cargo crossing the Yangpu first line is not counted as an import and does not consume allowance; in-zone STS transfer, re-documentation and re-export all run on the bonded ledger, moving the middle leg of the resale inside the free-trade fence.

But the boundary must be drawn hard. The text says within the Yangpu bonded port zone. Whether cargo crossing the second line into the mainland still needs allowances and automatic import licenses has no written confirmation from regulators. In other words, once cargo is meant for a mainland refinery or sale, the allowance and automatic license apply as before; Yangpu's convenience does not automatically spill outside the zone. Iron rule F10 nails do not extend Yangpu by analogy, and we cannot assume a national opening just because the zone is loose.

In practice the Yangpu route fits outside-the-customs-territory transit and re-export, not import substitution for mainland processing feed. If we use it, we stand up a separate in-zone entity, confirm bonded storage and STS anchorage support, and write no second-line extension into the pre-clearance clause of every deal — so no trader mistakes zone convenience for a national license.
