thats a possibility yes…
^ Banggood is not so stingy. They are not a run of the mill small business. Thinking in such pettiness would not have crossed my mind. Randomly accusing a merchant of devious behaviour without exploring so many possibilities is, nefarious.
Another item of note, if there is no manifest (item description), this could trigger a customs security check. Without a tracking number assigned, the paperwork was hastily done and so the parcel contents not disclosed.
In the two years I’ve done business with BangGood, there is but one instance where the parcel was lost. They offer me a credit or resent. The later was my choice and without fees.
Also got my order cancelled due to security check. My order was marked shipped with no tracking info, and a week later when I emailed them for it, they finally responded with the cancellation. I suspect they didn’t want to honor the price with the coupon that was provided here.
With regard to these problems, I have come to the conclusion that if you ask what is happening they will take the problem out of the easiest way: canceling.
All my parcels that were sent from China (via CN post) had that problem, some returned several times, but are finally arriving.
Some package took more 2 months from the shipping email.
I never asked what was happening, I just let it run.

Same thing just happened to me - ordered a light on 12/25 (no battery), it shipped out on 12/27, I asked where the tracking number was a few days ago, and they said it had been “returned to them for unforseeable reasons” - at what point were they going to tell me that? At first I was thinking it may still show up in my mailbox even after the refund, seeing as they don’t appear to have their act together, but now that I see all these posts about failing customs, I’m thinking its not very likely.
it seems to affect usa orders, guess something is causing it so chose different shipping options.
I too had an order “returned due to the failure of security check when passing the customs office”. I had to contact them when it passed the ‘delivery expected’ date. They responded with ‘choose another delivery method or request refund’ in an email. I chose another shipping method and got an email again saying the same thing. I replied the same and got another email with ‘choose another delivery method or request refund’. I gave up and requested refund and had the refund by 11/10/19. I paid for shipping insurance too. $200.99 discount with coupon from here. Definitely the most I’ve paid for a light. It wasn’t easy to pry that out of my wallet but it’s the brightest light in the world, right? 
They threw in a free charger when the order was placed. Had my money for a month and a half. I declare shenanigans. Ordered same from Neal with Black Friday discount and had it in two weeks (no free charger though). Have three more orders with BG placed Nov 19 2019, Dec 22 2019 and Dec 25 2019 which have not arrived yet but have shipped, supposedly. No tracking information on those at all (Why?). I’m not ordering anything more until they arrive. I thought tariff revenge but that really doesn’t make sense after thinking about it. First problem I’ve had with them in 45 orders but I’m putting BG last on my list of vendors. I don’t think they like to see those coupon codes. I have had items in ‘processing’ status with coupon discounts for weeks when the item page says in stock. Ya pays your money and ya takes your chances.

I, too, have just had this happen with a MF01 Mini (no battery) from Banggood. Something strange is certainly going on. Either they’re messing up paperwork, have switched to a pickier package handler, or something unusual.
My astrolux FT03 had been cancelled 2 times now. No battery the second time… /SMH … I can order all sorts of magpul knock offs all day long, LPK’s, scopes, replacement barrels. Car parts to cars not even available in the united states, No problem.
I can order tritium vials for my flash lights,
I can order medical supplies to include needles, saline, antibiotics for my fish, blood clotting agents, band aids,
Just no flash lights.
I’ve got a November order for an fw3a in the same boat. Stuck in China after returned for security scince Jan 6. I’m in Canada, and did not order a battery
My orders from BangUgood on Dec.25th were delivered Jan.15th no issues, no batteries either….
Banggood’s shipping option is their biggest weakness. If you pick a shipping option without tracking, it’s very likely it will fail the customs security check. The problem is that they don’t offer ePacket, which is the cheapest and quickest way to get things to the US (I recently had an Aliexpress order that arrive in the US after 8 days using ePacket shipping); and that their EMS option is outrageously expensive.
I’m wondering Banggood has any reps here so we can give them some feedback about their lackluster shipping.
