The obligation in the contract between SYAQ and PLL is delivery to North Carolina. The parties to the contract can always vary the terms (in writing, mutually agreed) if it is in their interest. For example, if it is cheaper for both SYAQ and PLL to redirect the shipment direct to a PLL customer then its a no brainer.... but lets say the cost was higher for SYAQ to do so, and PLL can avoid the costs of double handling, then PLL would offer to SYAQ compensation to redirect from the contracted North Carolina delivery point. This would need to be agreed beforehand, there would be no obligation for SYAQ or PLL to accept any proposed amendment.
