The key policy distinction between comprehensive bonded zones and bonded zones lies in their export tax rebate mechanisms, despite their similar names. It is essential to clearly distinguish between the two before conducting business.

The core difference lies in the export tax rebate rules. The comprehensive bonded zone falls under the category of comprehensive bonded areas and is eligible for a tax rebate mechanism with more prominent policy advantages.

There are clear boundaries for tax refund time points:

After domestic goods are exported into the Waigaoqiao Free Trade Zone, and the customs declaration procedures are completed and the goods are actually brought into the zone, enterprises can initiate a tax refund application based on the export tax refund certificate issued by customs, without waiting for the subsequent actual departure of the goods from the country, effectively accelerating the capital return process.

The rules for obtaining documents present a stark contrast. If domestic goods are exported into the traditional Waigaoqiao Bonded Zone, customs will not issue tax refund-related documents during the goods' entry into the zone. Tax refunds can only be processed when the goods are finally declared for departure. The business declaration process involves the "Outbound Goods Record List", resulting in a longer overall tax refund cycle.
