Shipping
We are an online wholesale platform and shipping costs are charged separately for greater benefit to you.
Air freight costs are based on the weight of the product (including packaging bags and cushioning materials). For products under 2kg, freight is calculated in 50g increments. For products between 2kg and 4kg, freight is calculated in 100g increments. For products over 4kg, freight is calculated in 1kg increments.
If your order exceeds 4kg or the shipping cost exceeds $70, we recommend contacting our customer service for an accurate shipping quote. You will need to provide your zip code address when you contact us.
Air freight options include DHL, UPS, FedEx, and Yun Express, with a delivery time of 7-12 days.
When the weight of the express delivery exceeds 12kg or air shipping cost exceeds US$100 or sea shipping cost exceeds US$50, you can choose B2B shipping:
Air freight(10-14 days)
Yun quik boat sea freight (15-20 days)
Quik boat sea freight(20-25 days).
