How to Add Box Content to an Amazon FBA Shipment (2026)

By Bernardo Campelo, Forbes Business Council E-Commerce Leader, Amazon SPN Certified provider, Amazon SP-API authorized partner, and Founder of PrepVia.

Picture the worst part of building an FBA shipment. It is not taping boxes or printing labels. It is sitting at Seller Central typing SKU, quantity, SKU, quantity, line after line, for hundreds of units, while the exact same numbers sit in the invoice your supplier emailed you yesterday. That is where sellers quietly burn hours, and it is where the transposed digit that costs you money slips in.

I have watched sellers do this across dozens of accounts, and the frustration is always the same: your supplier already sent you this data. Why are you typing it again? So let me cover what box content actually is, the three ways to provide it, what it costs you to skip it, and why the manual version is a problem worth solving.

The 60-second version

Box content information is the manifest that tells Amazon which SKUs and quantities are in each box of your shipment, so it can check your units in quickly and accurately. You can provide it three ways: the web form, an Excel or flat-file upload, or a 2D barcode on each carton. Skip it and Amazon applies a per-unit manual processing fee, because a worker has to open and identify every box by hand. Providing accurate box content is almost always cheaper than not.

Web form, Excel upload, or 2D barcode

The right method depends on how many SKUs and boxes you are shipping.

MethodBest forThe catch
Web form (Send to Amazon)A handful of SKUs and boxesTedious and error-prone past a couple dozen lines
Excel / flat-file uploadMany SKUs across many boxesOne formatting slip rejects the whole file
2D barcode (PDF417 / Data Matrix)High-volume, carton-levelIf the scan fails at the FC, you fall back to the manual fee

What it costs to skip it

If you do not provide box content, Amazon applies a manual processing fee, $0.15 per unit from January through October and $0.30 per unit in November and December, because staff have to open and identify each box manually. The rate is set by the month Amazon receives the first unit of the shipment, and it is charged 14 days later on the units received by then. On a 1,000-unit shipment that is $150 outside peak and $300 if the first unit lands in November or December. It also slows your check-in, which delays the moment your inventory is sellable. The fee is one of the easiest charges in all of FBA to avoid, and one of the most common to eat by accident.

Why the manual version is the real problem

The fee is the visible cost. The hidden cost is the data entry itself: the hours and the transcription errors that come from re-typing numbers a supplier already sent. The fix is not to type faster. It is to build the box content from the supplier’s packing list automatically, which is exactly what PrepVia’s intake does, it reads the document and turns it into matched line items instead of asking you to key it in. How that flows into receiving is in FBA inbound shipment tracking, and it is one of the thirteen tools every Amazon seller should expect from a prep center.

Frequently Asked Questions

What is box content information for an Amazon FBA shipment?

It is the manifest telling Amazon which SKUs and quantities are in each box of your shipment, so it can check your units in faster and more accurately. You provide it through the web form, an Excel or flat-file upload, or a 2D barcode on each carton.

How much is the Amazon manual processing fee if I skip box content?

It is $0.15 per unit from January through October and $0.30 per unit in November and December. The rate follows the month Amazon receives the first unit of the shipment, so a Q4 arrival doubles it. Amazon charges it when box content is missing because staff must open and identify each box by hand, so providing box content is almost always cheaper than skipping it.

Should I use the web form or an Excel upload for box content?

Use the web form for a small number of SKUs and boxes, and an Excel or flat-file upload when you have many SKUs across many boxes. The upload is faster at scale but unforgiving: one formatting error can reject the entire file, so the data has to be clean.

Can I avoid typing box content manually?

Yes. The same SKU and quantity data usually already exists in your supplier’s packing list or invoice. A prep center that builds box content from that document removes the manual re-typing, which eliminates both the wasted hours and the transcription errors that cause rejected feeds.

Your supplier already sent you this data.
