I am trying to find the maximum size measurements for the boxes to be shipped to Amazon for FBA

We have shipped a total of 22 boxes to Amazon. All were the same size boxes but 4 got flagged as being over sized. The measurement of the box is (w)70x(h)41x(d)25cm. In the defect report they have flagged it for being over sized and have indicated the height as being 70cm while the maximum should be 63.5. This has happened for 4 boxes out of 22.

What would you recommend I do? Also does anyone know the maximum weight a box can be?

My product weight is 160g and I usually send approx 24-25 per box.

The biggest permitted box is 63.5cm long except for items which are bigger. My boxes are 62 x 47 x 47cm.

The heaviest permitted weight is 23kg unless your item is more than 23kg. Over 15kg, you need to use “Heavy Package” stickers on 5 sides.

Here’s a quick guide to resolve your FBA box size and weight issues:

  1. Maximum Box Size for FBA:

Standard Size: 63.5 cm (25 inches) on the longest side.

Total Girth: Length + 2x Width + 2x Height should not exceed 266 cm (105 inches).

Your box (70x41x25 cm) exceeds the maximum height (63.5 cm), so it’s flagged as oversized.

  1. Maximum Box Weight for FBA:

Standard Box: 23 kg (50 lbs).

Heavy Box: If over 23 kg, it must be labeled as “Heavy Weight” and cannot exceed 31.5 kg (70 lbs).

  1. Recommendations:

Resize Your Boxes: Use boxes that comply with Amazon’s size limits (e.g., 63.5 cm or less on the longest side).

Check Measurements: Ensure boxes are measured correctly before shipping.

Contact Seller Support: Explain the discrepancy (e.g., 4 boxes flagged out of 22) and request a review.

Label Heavy Boxes: If any box exceeds 23 kg, label it as “Heavy Weight.”

  1. Prevent Future Issues:

Use Amazon’s FBA Box Size and Weight Guidelines to ensure compliance.

Double-check box dimensions and weights before shipping.

By adjusting your box size and weight, you can avoid future penalties and ensure smooth FBA operations.

Can you convert centimeters to inches, please?

Amazon’s maximum box dimensions for standard shipments are typically 63.5 cm on any side, so if Amazon flagged only 4 out of 22 boxes with the height listed as 70 cm, it’s possible they measured them incorrectly. You can open a case with Seller Support, provide your box dimensions, and request a remeasurement. If Amazon insists on the flagged dimensions, you may need to adjust your packaging for future shipments to ensure compliance. Regarding weight, Amazon’s maximum per box is usually 23 kg unless it’s a single oversized unit. Since your products are only 160g each, your total box weight is likely well within the limit.

This sometimes happens due to wrapping tapes and certain edges. Ask Amazon to recheck the measurements, otherwise, there’s no further solution at this point.

You need to redesign the box so that all sides are less than 63.5 cm. As for weight, as long as the total box weight (including product and packaging) is less than 22.7 kg, it will be fine, but it must meet Amazon’s current standards.

You don’t have a calculator?

Thank you for your feedback. I guess I was just confused as they accepted so many and flagged these 4. I will find new boxes.
