If the GBC products you sell on AliExpress are considered to infringe on the intellectual property rights of others, and you do not handle it in time, you may face the following risks and consequences:

1. Complaints and removal from shelves: AliExpress has the right to remove infringing products from shelves based on intellectual property complaints, and may even close your store.

2. Compensation for losses: If your sales behavior is determined to infringe on the intellectual property rights of others, you may be responsible for compensating for losses, including compensating the infringer's economic losses and mental damages.

3. Legal proceedings: If the infringer takes legal action, you may need to face legal proceedings and bear greater legal risks and economic responsibilities.

Therefore, if you receive an intellectual property complaint, it is recommended that you handle it in a timely manner and cooperate with AliExpress's investigation and handling to avoid unnecessary risks and losses. At the same time, it is recommended that you understand the relevant intellectual property laws, regulations and policies before selling GBC products, comply with relevant regulations, and protect your legitimate rights and interests.
