Import Tips
• For deuterated THF, confirm whether the deuterium content affects classification; it typically does not, as it remains the same chemical compound
• Provide a certificate of analysis showing the 99.96% purity to support the classification
• Ensure the product is packaged in containers suitable for laboratory use, as retail packing could alter the tariff classification
