Frequently Asked Questions (FAQ)

A: All our portable essential oil diffusers come with full international certifications including CE, FCC, RoHS, and EMC. The lithium-ion batteries also have MSDS certification and air freight safety reports, so you can ship them safely by air without issues.

A: For standard models that we have in stock, we can ship within 5-7 days after receiving your deposit. For custom orders (custom branding, colors, or packaging), lead time is typically 15-30 days depending on the order quantity and scope of customization. We always provide a firm delivery date when you place your order.
A: Yes, we offer complete custom branding services including silk-screen printing, laser engraving, custom color matching, and custom retail packaging. And unlike many Chinese factories, we offer this service even for small trial orders – you don’t need a 300+ unit minimum to start your private label brand. Even 1 unit can be customized.
A: For our UHF and two-fluid waterless portable diffusers, you need pure essential oils with good fluidity (viscosity ≤ 45 Cp). This includes most common essential oils as well as many woody and resinous oils like sandalwood, frankincense, and patchouli. For oils with higher viscosity, dilute them with a compatible aromatherapy base solvent before use. It does not support water-based perfumes.
We support custom colors starting from 500 units, and there is no limit to the quantity of custom packaging boxes. Please see the page link for details:https://wholesalediffuser.com/oemodm/
A: Yes, we welcome sample orders to let you test the quality and performance before committing to a larger purchase. You can order just 1 or 2 units to evaluate, and we’ll credit the sample cost back to you when you place your first bulk order.
A: Yes, absolutely. All our lithium-ion batteries come with full MSDS certification and air freight safety reports, so they can be shipped legally by air without any issues. This speeds up delivery and reduces lead times to your warehouse.
A: The UD series diffusers feature a leak-proof design and an anti-accidental-touch switch; they require a long press or three consecutive presses to turn on, so they can be placed anywhere. However, for other models, the essential oil should be poured out before putting them in a bag or suitcase, and there is a risk of accidental activation due to the touch button.
Portable diffusers are typically made of materials such as aluminum alloy, glass, and PA6. We provide by default packaging boxes wrapped in pearl cotton and EVA. All diffusers have passed drop tests, so their packaging is very secure. We will fully compensate for any losses caused by damage during shipping due to our packaging.
