Import Tips
• Ensure the ceramic frames are fired after shaping and not merely dried, as unfired articles are excluded from Chapter 69
• Keep technical documentation showing the memory stack's use in laboratory or technical applications to support classification
• Verify whether the item contains any excisable goods, which may affect duty calculation
