Most of the Chinese companies we (the responsible laser enthusiast community) order from tend to mark things in a way that it should not get caught by customs.
I have an order in process (it's just passed through a Chinese sort facility) from Lazerer, and I wasn't concerned that it would be confiscated at all when I placed my order. Besides, if you're worried with Lazerer, you can tack on $1.99 for insurance, and if it does get taken by customs, you get your money back or another shipped for free. I did that anyway so that I get tracking.
I've placed many orders from Laserlands, which many would argue is not at the same level of quality of service as Lazerer by far, and every package arrived timely with no customs issues. Each was marked as "flashlight" or "electronic parts" with an apropriate value to not cause suspicion.
IMO the only things you have to worry about are when the company marks it as a laser or if the company's shipping address has the word laser in it.
That being said, if you are truly worried, just DIY. Order a complete module from DTR, grab a host you like from someone on here, and put the two together. Some hosts don't require any tools at all to work with, especially if you use an all-incusive module. My next laser will be a DTR 405nm module and a Eudaimonium host.
