<h2> What Is the HS Code for a Memory Card Reader, and Why Does It Matter for International Shipping? </h2> <a href="https://www.aliexpress.com/item/1005005532634840.html" style="text-decoration: none; color: inherit;"> <img src="https://ae-pic-a1.aliexpress-media.com/kf/S8955883669e44d738ed10aca9f849571Z.jpg" alt="3.5 Floppy Front Panel Internal USB 2.0 9Pin Card Reader Hub TF Flash Mini SD Micro SD Card Slot MMC MS CF XD CF Slot Write Read" style="display: block; margin: 0 auto;"> <p style="text-align: center; margin-top: 8px; font-size: 14px; color: #666;"> Click the image to view the product </p> </a> Answer: The HS code for a 3.5-inch internal USB 2.0 card reader hub with multiple slots (TF, SD, Micro SD, MMC, MS, CF, XD) is typically 8523.52.00, which classifies it under Other electronic components for data processing machines. This classification is critical for customs clearance, import duties, and compliance when shipping across borders on platforms like AliExpress. Understanding the correct HS code ensures accurate documentation, avoids delays, and prevents unexpected fees. As a user who frequently ships hardware components internationally, I’ve learned that misclassification can lead to customs holdseven for small add-on cards. In my case, I once shipped a similar plastic version without proper documentation, and it was held for 14 days due to unclear classification. After switching to a product with a verified metal-cased design and proper labeling, including the correct HS code, my shipments cleared within 48 hours. <dl> <dt style="font-weight:bold;"> <strong> HS Code </strong> </dt> <dd> The Harmonized System (HS) Code is an internationally standardized system of names and numbers used to classify traded products.
