How many taels of silver are broken

Recently, Shuikou Customs seized 2 batches of silver particles weighing 5 kilograms in the travel inspection channel.
When the customs officers of Shuikou Port were conducting supervision in the travel inspection hall, they found two outbound passengers with anxious expressions and suspicious behavior. The on-site customs officers immediately intercepted and further inspected the two passengers, and found that they were wrapped in three and two transparent plastic bags respectively with clothing. The bags contained silver white granular metal products, suspected to be silver particles. After appraisal by the Nanning Customs Technical Center, it was determined that the silver content of this batch of metal particles exceeded 99.8%, with a total weight of 5 kilograms. At present, it has been transferred to anti smuggling for further disposal.
