This is already in effect and just implements the ASEAN-AFTA free trade (tariff elimination) agreements made before.
For vehicles, that means that when we get CBUs from Malaysia, Thailand or Indonesia no tariff is charged upon entry here in the Philippines. In the same manner, when we export CBU vehicles (like the Focus & Mazda3) to the same countries (plus Vietnam and Singapore) they don't impose a tariff like before.
but some articles say it's still not in effect due to insistence of CAMPI to exclude used CBUs. so CBUs from japan and korea are included in this EO? and if this is really in effect, how come the prices of toyota thai CBUs and some CBUs from thailand that are sold by honda, mitsubishi, chevrolet and isuzu have not yet decreased?
I think what CAMPI is protesting would be the increase CBU and reduction of CKD units entering the country. What's funny though is that the only volume exporter of CBU units is not a member of CAMPI (Ford / Mazda).
CBU units from Japan are covered under the JPEPA. We have a similar agreement (ASEAN-Korea FTA) for Korea though.
