Is there any legal way to prevent my customers from having to pay customs/tariffs when selling internationally?

I am about to launch an ecommerce business that sells customisable products. These products are customised in our manufacturing unit in South East Asia. However, the target market is the US. If our customers would have to pay customs/tariffs on each product sold I feel that would kill the business model. However, I can't ship the entire inventory to the US at once since each order needs to be customised in the manufacturing unit in Asia. Is there any way to avoid the customs issue? Perhaps by finding a redistributor in the US or do I need to incorporate my business in the US as well? I'd be extremely grateful for any help or advice
