Whether Alibaba contract purchases are refundable depends on the specific terms and refund policy in the contract. Usually, buyers and suppliers in contract purchases will negotiate refund terms in advance to ensure that buyers can get a refund in specific circumstances (such as delayed delivery, quality issues or breach of contract). The specific refund process and time frame will also be clearly stated in the contract. Therefore, buyers should carefully review the refund terms before signing a contract purchase agreement to understand their rights and protections.
