Legal analysis: Customs has the right to detain, but it also needs to handle it in accordance with relevant procedures. If you are detained, you will be punished, and the amount will involve a crime.
Legal basis: "Regulations of the People's Republic of China on the Customs Protection of Intellectual Property Rights" Article 24 Under any of the following circumstances, the customs shall release the detained goods suspected of infringement. The customs shall comply with these regulations. If goods suspected of infringement are detained in accordance with the provisions of Article 15 and no notice of enforcement assistance is received from the People's Court within 20 working days from the date of detention, the customs shall detain the goods suspected of infringement in accordance with the provisions of Article 16 of these Regulations. The consignee or consignor of goods suspected of infringing patent rights has not received a notice of enforcement assistance from the People's Court within 50 working days, and upon investigation it cannot be determined that the detained suspected infringing goods infringe intellectual property rights. After paying a security deposit worth the amount, request the customs to release the goods; the customs believes that the consignee or consignor has sufficient evidence to prove that the goods do not infringe the intellectual property rights of the intellectual property right holder.
