§12A-2-503.
   
   (1) Tender of delivery requires that the seller put and hold
   conforming goods at the buyer's disposition and give the buyer any
   notification reasonably necessary to enable him to take delivery. The
   manner, time and place for tender are determined by the agreement and
   this article, and in particular
   
   (a) tender must be at a reasonable hour, and if it is of goods they
   must be kept available for the period reasonably necessary to enable
   the buyer to take possession; but
   
   (b) unless otherwise agreed the buyer must furnish facilities
   reasonably suited to the receipt of the goods.
   
   (2) Where the case is within the next section respecting shipment
   tender requires that the seller comply with its provisions. (3) Where
   the seller is required to deliver at a particular destination tender
   requires that he comply with subsection (1) and also in any
   appropriate case tender documents as described in subsections (4) and
   (5) of this section.
   
   (4) Where goods are in the possession of a bailee and are to be
   delivered without being moved
   
   (a) tender requires that the seller either tender a negotiable
   document of title covering such goods or procure acknowledgment by the
   bailee of the buyer's right to possession of the goods; but
   
   (b) tender to the buyer of a nonnegotiable document of title or of a
   written direction to the bailee to deliver is sufficient tender unless
   the buyer seasonably objects, and receipt by the bailee of
   notification of the buyer's rights fixes those rights as against the
   bailee and all third persons; but risk of loss of the goods and of any
   failure by the bailee to honor the nonnegotiable document of title or
   to obey the direction remains on the seller until the buyer has had a
   reasonable time to present the document or direction, and a refusal by
   the bailee to honor the document or to obey the direction defeats the
   tender.
   
   (5) Where the contract requires the seller to deliver documents (a) he
   must tender all such documents in correct form, except as provided in
   this article with respect to bills of lading in a set (subsection (2)
   of Section 2-323); and
   
   (b) tender through customary banking channels is sufficient and
   dishonor of a draft accompanying the documents constitutes
   nonacceptance or rejection.
