sent a package as a mail

[mayakane-4]

I sent a bubble mailer (6 by 9) with a makeup item (lipstick) in it. I sent it as an envelope. The postage that I got was USPS FIRST-CLASS MAIL and a letter F. The postage costed $1.21 and I didn't get a tracking number. The package weighted 1.60 oz. Is it going to be delivered okay, or is it going to be send back?

It is certainly NOT an envelope.

Several possibilities now:

-- by luck the buyer may get it

-- by luck the buyer may get it AND file an INR

-- the PO may charge the buyer for extra postage

-- the item will be returned to you (an INR and negaive feedback)

-- maybe some other thing that I haven't thought of

You can’t send merchandise via lettermail. You purchased the wrong label. You need to use first class package. No one knows if it will be delivered today. You have no seller protection without a tracking number. If the PO catches you, they may charge you the correct rate for first class package. They may deliver it to the buyer with postage due (which you will need to pay).

$1.21 is the rigth price for that size envelope, but it depends upon how thick the envelope was, 3/4" is the limit, and whether it has more than a 1/4" in variation of thickness overall.

If the listick item is typical, then even if it were in a non-bubble envelope, I think you would be nonconforming on variation and probably nonconforming on thickness.  I can't see how a typical lipstick item in a bubble envelope could be less than 3/4" thick.

So at a minimum you would be upcharged to a First Class Package price of $3.50.  Whether the new automated system is capable of catching this type of discrepancy, we don't know for sure.  We also don't know if you did electronic postage or stamps***.  If electronic postage the new system would bill you if caught.  Not sure how the new system would work if stamped....maybe it prints something on the package to alert the letter carrier to collect short paid postage upon delivery?

***Re-read you post and saw you have a Letter F wich means it is electronic.

Traditional lipstick is 3/4 inch thick.  (3/4 × 3 × 3/4) 

Definitely does not meet the limit of FC flat. 

Like what the previous posters said, the USPS will catch it. You should hope that it will be delivered to the buyer and that USPS will just bill your Paypal account for the underpayment or the correct FC postage. It is an embarrassment if the buyer will be asked to foot the bill.

The lumpy item in a letter could get caught in machinery and the envelope torn, the item crushed or missing.

Even if an envelope is under 3/4 inch thick, it cannot be mailed as a flat (AKA Large envelope) if it has 'irregular thickness" which USPS defines as a variation in thickness more than 1/4 inch.  It's nearly impossible to mail a lipstick in a padded envelope while meeting the criteria for a flat.

If USPS notices that your item should have been sent as a package rather than as a flat, there will be Postage Due of $2.29.  The item will be returned to you if the discrepancy is discovered while it's still in your region; otherwise, it will be delivered to your buyer with Postage Due.

Or APV will catch it and upcharge for/as 1lb Priority Mail?
