Hi @Seller_TVHvMEuUWpNvH,

Under the "Poly-bagged units" section at Packaging and prep requirements, Amazon notes that "highly scented products (such as candles) must be sealed or bagged to prevent the absorption of the scent into other products."

As for safety certificates, the Product compliance page mentions that certain products need to meet specific certification standards, but it doesn't detail the requirements for candles. Since you're looking for exact certificate requirements, I'd recommend reaching out to Seller Support - they should be able to give you the most up-to-date information for your specific product.

Best regards, Michael
