Import Tips
• Confirm the purity and chemical identity with a certificate of analysis to support classification
• If the product is for research use only, ensure it is not put up for retail sale to avoid reclassification
• Check if any added stabilisers or anti-dusting agents are present, as they must be necessary for preservation or transport
