The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Ensure the adapter plate is not classified as a part of a machine of heading 84.28 (other lifting, handling machinery) — if it is a complete handling device, it may be excluded
• Provide documentation that it is a part of a wafer sorter
• Confirm no electrical features are present
