What is the primary obligation of buyers under international sales contracts?

The primary obligation of buyers under international sales contracts is to pay the price and comply with necessary formalities. This reflects the core balance in any sales agreement where the buyer's responsibility primarily centers around fulfilling financial obligations and adhering to any procedural or regulatory requirements that facilitate the transaction.

By agreeing to pay the price, the buyer acknowledges their commitment to the financial aspects of the contract, which cannot be overlooked as payment is crucial for the transfer of ownership and the overall success of the sale. Additionally, compliance with necessary formalities encompasses understanding and following any legal requirements associated with international trade, such as customs procedures and import/export regulations, which are vital for the smooth execution of the sale.

The other options pertain to important but secondary responsibilities that do not represent the primary obligations of buyers. For instance, while the provision of correct delivery documentation is important for the seller to facilitate the shipping process, it does not fall within the buyer's fundamental duties. Quality control of received goods is significant but typically relates to the buyer's rights after delivery rather than their primary obligations. Lastly, negotiating contract terms is essential in establishing the agreement but represents a preliminary stage in the relationship rather than a continuing duty once the contract is formed.
