32 ECT vs 200 lb Test Corrugated Boxes
32 ECT and 200 lb test rate the same thing - the strength of single-wall corrugated - two different ways. 200 lb Mullen burst test is the older spec; 32 ECT (edge crush test) is the modern equivalent box makers and carriers now use. For most ecommerce shipping up to roughly 65 lb gross, an ECT-32 box is the standard choice, and it is what Packrift stocks.

FAQ
- Is 32 ECT the same as 200 lb test?
- For single-wall corrugated they are treated as equivalent: a 200 lb Mullen burst box and a 32 ECT box carry about the same gross weight. Packrift lists strength as ECT, so order the ECT-32 boxes below for a 200#-equivalent box.
- What if my buyer's spec sheet still says 200 lb test?
- Order ECT-32 and note the equivalence, or send the spec via the bulk quote path so we can confirm against current catalog data.
