Here is a copy of the bill from UPS on that shipment of 9 x S7's with the classification of 8523.51.00.  Notice there was no "Duty Amount" because it was FREE on this shipment.


The whole damn thing just pisses me off.  I think someone in customs that day saw "BITCOIN MINER" and was like, "What the hell is that?"  I'll just label it under "Other" and charge 2.6%.

You can bet your ass I'm disputing this with customs.

I just got a bill from UPS for the first time also. Mine was classified as 8487.90.0080. Do you have a link to the Duty Class manual? Have you contacted UPS yet? It appears that UPS reps are randomly classifying the miners and imposing a duty.

now "other" seems to be 3.9% fee. Why is this not a computer or computer part? Not sure about silicon storage device-even that is better.
Honestly, this is what Bitmain should be doing (providing a valid tariff code to customs)
Spondoolies was providing HS code to customs last year: 8471-7000 (I checked and it appears to correspond to Storage units without further classification).
8523.51.00 seems to be essentially the same as SPT code above, so either should be good as they describe the same thing.

is https://bitcoinwisdom.com/bitcoin/calculator a good place to calculate ROI? i keep messing with this thing and still cant find ROI.....everytime i do it im in the hole $700+ after 200+ days. these things need to be cheaper. and with the reliability issues of late, i think im better off just buying a bunch of btc and seeing if it increases in value over those 200 days...when stuff lasts 2 weeks and burns up or fails..... that means it is total crap!

I quick call to UPS solved the issue, they just wanted to make sure what type of device it is. I told them that it is a data processing machine which does nothing but data processing. I received an email that the fee will be credited to my account in 6-8 weeks.

My batch 9 arrived today, had to pay UPS about $30 upon delivery.

My first S7, but I notice some differences from the other S7 pictures.  The controller board on top only has 3 connector ports for the 3 blades, there are no other ports to connect cables to.  Also, the PCI-e power connector on the board is upright and not to the side.  Also, only 2 fan ports on the controller board.  Is this different from the batch 8s?

You probably got a B8, B9 are not scheduled to ship until the 20th. B8 and 9 are similar in design, 3 data ports and 2 fan ports.

Might be the same, but I ordered a B9 before the price drop, then received an e-mail that my S7 would ship early (04 Jan. instead of 20 Jan.) due to the price decrease.  So it's supposed to be a B9.  Hopefully they are the same if it's a B8.

B9 is B8 with a later shipping date.

[fr4nkthetank]

Yeah.  Pretty sure b8 is final batch variation.  So batch numbers will simply = shipping time, as before.  Made me wonder, just now, why all the batch variations until batch 8.  I think I know why, call it a hunch.  See all that hashrate going up ?  difficulty going up like crazy ?  Bitmain is responsible for a sizeable part of that, but the fact is that they were in a RUSH to sell these s7's, and they needed to ship them out asap.  each week that passed by was loss of money, as the other players were bringing lots of hash power online.  Plus halving.  Idk, my2cents.

[fr4nkthetank]

Also I have a question for the last thread page.  You guys say keep fans at 50% in case of disconnect,etc.  I'm at 33%, 57-60c temps.  I'm guessing that is very safe.  How can the miner work "harder", or hotter if the internet disconnects ?  manual fan settings, my guess is temps wont change by a single degree.

not mine, my friend's s7, not b8 though .. for your viewing pleasure :

did that start from the board or the pcie cables?

WOW!  How in the world did that happen? 

[yslyung]

just a standard s7 no oc nothing powered with server psu.

not mine my friend's s7, sad to see though.

That is REALLY ff'd up sir.

[djroadking]

Damn... Was his unit overclocked at all?

Had that been running very long when it happened?

Some people get all the fun.

Looks like the fire started in the hashing chip area, then moved on up the board. Interesting, was this person using a normal power supply or one of those monster rail concepts that power a lot of miners off a common bus?

If so one should ensure that they have an appropriately rated fuse on each tap that goes to a miner, because those power planes are probably only designed for a max input current of 100a or so (1,200 watts). A single power supply would crowbar. Or run the risk of burning your mine down, things happen.

How does the other side of the board look?

I'm curious...  Does your electricity rate per kWh need to be cheaper?

I just got a bill from UPS for the first time also. Mine was classified as 8487.90.0080. Do you have a link to the Duty Class manual? Have you contacted UPS yet? It appears that UPS reps are randomly classifying the miners and imposing a duty.

That code they gave for yours was just made up out of thin air.  BITMAIN, should be providing a proper code for us but they are not.  I have asked UPS to give me a phone call from this day forward anytime I have a shipment arriving into the US for me from another country.  If I miss the call and they have to call me again they will charge me $10.00.  I'm fine with that.  I prefer to have hold my package(s) until they get in touch with me and ask me for an HST code than having to go through this mess of wondering if I will have to pay $800 or more to the government.

The code they gave for yours has nothing to do with bitcoin miners.

Hell, they are making me go through a lot of red tape.  I had to send them a lot of information with photos and specifications of the rigs.  You must not have owed much at all.  Mine bill was almost $900 total for 23 rigs.  They have it on hold as far as me owing anything but it's possible I may get a bill 6 to 8 months from now with the same bill.  So, I have to sweat it for a while.

My bill was for 1, only $67 @ 3.9%.

5.9 cents a KW. which is low for most of the USA....
