Any vessel carrier engaging in cargo and passenger liner services shall file its freight and passenger tariffs with the shipping administration.
The tariffs mentioned herein before shall include various additional surcharges, methods of calculation, terms and conditions, and rules and regulations of transportation. The tariffs of the vessel carrier who joins a freight conference or consortium may be filed collectively by the conference or consortium, or its representing organization in ROC territory.

Any revision made to the tariffs for liner services, which have been filed by a vessel carrier, shall be filed (see Attachment 12) with the shipping administration. The revisions shall be effective subject to the requirements as follows:
1. For an increase of rate or the case that the freight amount will be increased due to the increase or decrease of tariff items, the revision shall be effective from the thirtieth day after filing and inspection. However, the addition of surcharges by reason of proper grounds and approved by the competent authority may be effective within thirty days.
2. For a decrease of rate or the case that the freight amount will remain unchanged or be decreased due to the increase or decrease of tariff items, the revision shall be effective from the day of filing and inspection.
