Bambu Order Seized by USPS For Counterfeit Postage

[realchasecurtis]

I ordered a set of nozzles on the 14th, and today, I received a shipping update that my package has been seized by the Postal Service.

“The package associated with this tracking number was found to bear counterfeit postage and is now considered Postal Service property under USPS regulations and will not be delivered. You are encouraged to contact the sender/merchant and/or your credit card company, as applicable, to seek a refund or other available recourse.”

Typically, my orders go from Houston to my front door in 24 hours or less, but this one went to Pittsburgh, PA to Warrendale, PA to White Plains, NY to Indianapolis, IN to “Seized.”

I spoke to live support and they assured me that this is normal, and I should receive my package after a postage assessment.

Has this happened to anyone else?

I’ll keep this updated…

Send a copy of the USPS seizure notification to Bambu’s customer support, see what they say…but be prepared to request a charge back to your bank…just to be on the safe side.

Someone on reddit posted this same thing happening yesterday. (unless that was you)

[realchasecurtis]

Sadly, I paid with gift cards…

[drakko]

Still worth a shot at Bambu’s customer support…maybe (emphasis on maybe):
a) they’ll sort your shipment out (they might), or
b) they’ll send you another shipment (unlikely, yet miracles do happen now and then), or
c) just let you to hang dry (that happens more often than not, according to those who got burned)…

What you’ve got to lose (more than what you’ve already lost)?

Congrats you just became a victim of someone pirating your shipping label. This happens when someone who likes scamming sniffs this valid tracking number (thru a variety of means that I wont get into here) and then inputs it as fraud into some sales app as they pretend to dropship fulfill an order to someone entirely else, nearby. It’s like shipping them a brick, but without actually having to make a shipment, in a way that tricks the payment vendors to processing the transaction. Edit: it normally will be ok, but they gotta stop for a moment and determine who cloned who

Not Bambu but Anycubic. I have screen protectors and fresnel lens. Ordered from them plenty of times yet mines being held as well. I get insufficient postage, and anycubic swears it’ll be here. Holding has never been an issue with any package.

I have it in mind that with the USPS click-n-ship online postage and those 3rd party vendors, something like this can happen. But this is the first time I ever heard about it. Good to know. I would have dismissed this kind of messages as phishing emails.

Just in case, OP probably should create a ticket to ensure someone in BL stays on top of it to avoid further delay.

Oh mine too! I have nothing to do with Bambu lab but your message popped up in Google search. I’ve been selling for 5 years and been using USPS the whole time. This is the first time this happened, and we paid postage even before handing our parcels to them. This is crazy! We are serious in business, why would we do that kind of thing? I just did a quick Google search and saw quite a few of these that happened within the last couple of days. I suspect there’s some issue with USPS’s internal system. My customer is going to lose trust in our business now - thanks to USPS.

It’s good to know that USPS told you that you will receive your package after a postage assessment. On Sep 19, mine says ‘Delayed for postage assessment, held awaiting payment’, and then it continued delivery on Sep 22, but ever since it says ‘In Transit to Next Facility’ until today it suddenly says that it’s been seized by USPS. Please keep us posted on what happens. I will do the same. Thank you!

This is one of many reasons that I only use ‘official’ tracking pages of any shipper I use. It makes no sense to use a page called USPS Tracking that isn’t from a USPS website.

[Bullocks]

This is not unique to USPS, it is a vulnerability being exploited between dropship scammers and payment vendors - Your tracking number (from ANY vendor and ANY carrier) is able to be used in this scam as a disposable receipt that allows them to run away with the money a lot easier. They dont know you, your recipient, the USPS route, or anything about your business. All they know is that someone on facebook in a targeted zip code just bought their fake Freedom Patriot Labubu or whatever, and theyre lying to visa saying that YOUR tracking number is THEIR shipment.

good to know that USPS told you that you will receive your package after a postage assessment.

I think OP contacted Bambu Live Chat, not USPS, but I could be wrong.

This is most likely some hiccups in the system. Unfortunately it can hurt the customer experience. But I have since heard that postage obtained through some unknown third-party vendors can be fake. Use the click-n-ship directly from USPS or a reputable third party vendor.

[R3d-Five]

you should try 17track though. ive used it for at least 10 years and it tracks everything

[TomWS]

Thanks for the suggestion. But back to my point, why would you use a third party tracker? That is an invitation for siphoning off data of some sort.

[R3d-Five]

by inputting a tracking number? I don’t see how. I doubt that tracking numbers are encrypted anywhere.
I use a third party for several reasons. One is accurate information in one place. If I have 10 tracking numbers across DHL, UPS, USPS, YunExpress it’s far easier to get the info in one place than to bounce back and forth. I also get delivery or exception notifications faster.

If i’m looking for your package something like 17 can give me more detail than just “Louisville 13:01” Like flight, or arrival, what it’s doing and what time it left.

I don’t see any reason not to.

Oh, and I now have 2 that have counterfeit postage. I do believe this is more than just an oops. I’ll keep my tin foil to myself but I’ve yet to hear (across multiple platforms) of any domestic having counterfeit postage. These companies ship millions of dollars of merchandise a year and have never used counterfeit postage. I really doubt they’ve just started or our Postal Service just caught on.

[R3d-Five]

I’ve had 2 lost just today. They changed from insufficient postage to seized. the funny thing is it’s Anycubic and it just happened. Used these guys for years and I doubt they’re internally buying fake postage.

Adding a note to the bottom (now of this thread regarding and for those that have had it happen reply across the board, even if it’s not BL)

@BambuLab
Fellow…fellows,
I’m writing this because something’s wrong—and it’s not just a one-off.

Over the past few weeks, I’ve had multiple packages seized by USPS for alleged counterfeit postage. These weren’t random orders. They were replacement parts from a vendor I’ve trusted for years—one free, one paid. I never received them. They were intercepted and taken.

Now I’m seeing similar reports from other customers, including shipments tied to Bambu Labs. That’s not a fringe brand. That’s a major player in our space. If their packages are getting flagged too, then this isn’t about shady sellers—it’s about a systemic enforcement shift.

Let me be clear: counterfeit postage is a real problem. There are bad actors out there—some overseas, some domestic—who knowingly defraud USPS and undermine legitimate commerce. I’m not defending fraud. I’m not defending any brand. I’m saying that when enforcement gets this aggressive, even honest vendors and customers get caught in the crossfire.

USPS is treating counterfeit postage as grounds for seizure. Not return. Not notification. Just gone. And if fulfillment partners or postage aggregators are cutting corners, it’s the end customer—us—who pays the price.

This isn’t about blame. It’s about transparency. If you’ve had packages seized, flagged, or mysteriously vanish, speak up. If Bambu or other vendors are affected, they need to address it publicly. Silence helps no one.

We’re customers. We rely on trust, reliability, and access to parts. If enforcement is changing, we deserve to know. And if vendors are caught in the crossfire, they need to tell us—not leave us guessing.

If you’ve been affected leave a note, even it it wasn’t BL package. If you know the carrier add them too.
—John

edit:The USPS Counterfeit Postage Reporting System (CPRS) went live on September 26, 2025, signaling a major escalation in enforcement.

would also like to acknowledge that YunExpress was the shipper for my 2. However they do not have a history of fraudulent postage and handle Amazon as well as other big brands.

Update #1:

It’s now been 4 business days since the package was “Seized by USPS for Counterfeit Postage.”

This morning, I got on the phone with the USPS Theft department, and they said if I’m seeing the Counterfeit Postage label/warning, the package IS NOT coming. The postage has failed all checks, and it’s at its final resting place.

However, I opened a case anyway to see if I can get in touch with the holding/seizure facility directly to discover what happened.

Update #2:

Normally, my account orders are updated on BL, and accurately reflect their stage in the shipping process.

This nozzle order never moved past processing, which leads me to believe someone didn’t follow the system or there was, in fact, fake postage.

Update 3:

Browsing the web for posts pertaining to counterfeit postage in the last month has turned up many results. It seems nearly all of these “false flag / counterfeit postage” alerts are stemming from companies of Asian origin.

Theories:

1. USPS is cracking down on companies of Asian origin [shipped internationally or within country] without discrimination and honest businesses are getting caught in the crossfire.
2. Asian companies are committing fraud on mass scale leading to increased and real seizures with no way to confirm the fraud. USPS won’t disclose package details outside of “seized” or not seized [i.e. you get your package], and of course, the companies we’re ordering from aren’t going to openly admit to fraud.
3. The tracking number scam as mentioned in other comments.

Update 4:

BL support is telling me for the second time to wait 1-3 business days [after waiting 4 business days] for the package to update and go back to in-transit.

They’ve informed me that they will send a replacement package if this first one is not received, but will not provide a timeline on when they would consider sending a new package.

As of today, the package has been in transit for ~16 days and seized for almost a week.

Update 5
Bambu support has asked to confirm my address for a replacement package to be sent out.

The Postmaster has gotten back to me and confirmed fraudulent postage. Additionally, the package’s tracking information does not match my address. The package’s destination was Rye, NY.

He is going to try to get me a picture of the label on the package, but said the request can take an unknown amount of time.

It seems like option 3 in “Theories” might be the most likely reason for this mishap - gotta love scammers.

[greenboots]

Somebody just had this happen and posted on Facebook in the bambu women’s group

[drakko]

Who was the carrier? Shipping straight from Bambu’s own warehouse, or from a 3rd party/ reseller? International shipping (China or elsewhere) or domestic (US)?

[realchasecurtis]

Domestic. USPS. From the Houston location [where most of my shipments come from].

Update 6:

The Postmaster has sent me an image of the label. It clearly says the proper address. The postage was either being reused [counterfeit] or someone “stole” my number and rerouted.
