What happens to the quota status of merchandise subject to BTA if PN is not satisfied but all other entry data would be acceptable? Is quota denied until PN is satisfied?

No importation of quota merchandise can be made until PN is satisfied. Release cannot occur; entry and/or entry/summary cannot be properly filed. The fact that the merchandise might be subject to a quota must be dealt with after PN is satisfied, as a condition precedent to entry being made. However, CBP will allow some very specific HTS number changes be made in the case of tariff rate quota merchandise, even after Prior Notice has been satisfied.
