As with the buyer's remedies, the seller's remedies are not categorized according to the kind of breach (cf. Article 61(1)). Article 64, however, contains special rules for the seller who wishes to avoid the contract when the buyer breaches his obligations to pay or to take delivery. In addition, for sales subject to the buyer's specifications, Article 65 provides, as a special remedy, the transfer to the seller of the right to specify the goods. The buyer's obligation to pay interest, provided for in Article 78 - one of the obligations in Chapter V which are common to both seller and buyer - is a special remedy for the seller when the buyer delays payment. The right to resell the goods, described in Article 88, is a remedy which becomes important to the seller when the buyer fails to take delivery of the goods. The seller's primary claim is for specific performance by the buyer (Article 62); however, Article 28 may limit the action.[333a] A notice extending the time to perform operates initially only as a bar to the seller's resort to other remedies for the duration of the extended time period, except for damages caused by the delay in performance (Article 63(2)), unless the buyer has refused to perform altogether (Article 63(2) sentence 1). In addition, the seller can claim damages together with specific performance or other remedies for the buyer's breach (Article 61(2)). Even if domestic law permits it, domestic courts and arbitral tribunals may not grant a grace period to the buyer - any more than they may grant one to the seller (Article 61(3)).
