Import Tips
• Classify the heat exchanger as a part of the grinding machine if it is presented separately, but be aware that if it is imported with the grinder, it may be classified as part of the complete machine
• Keep records of the end-use in semiconductor wafer preparation to support the classification
• Check if the product is eligible for duty relief under the Customs Tariff's provisions for goods used in manufacturing
