SELECTION EXPERT ADVICE

Wall Strength and Board Grade
MORE INFO
Single-wall corrugated handles most standard shipments, while double and triple-wall construction is built for heavy, sharp-edged, or high-value loads. Matching the board grade to your product weight prevents in-transit damage and avoids the cost of replacing goods that arrive compromised.
Size Selection and Dimensional Weight
MORE INFO
Choosing the right box dimensions for each SKU directly reduces what carriers charge in dimensional weight fees. A properly sized box also means less cushioning material needed to secure your product, which brings down both your material cost and your pack time per order.
RSC vs Specialty Box Styles
MORE INFO
Standard RSC boxes work well for most applications, but specialty styles like flat, cube, multi-depth, and telescoping boxes give you more flexibility for irregular products, retail display setups, and high-volume packing lines where a tighter fit around the product makes a real difference.
Overview

2,244 corrugated boxes from 4 to 36 inches: ECT-32 kraft shipping boxes, white literature mailers and multi-depth cartons in bundles of 10, 25 and 50. Inside dimensions, board grade and bundle size are listed per product, and the same box is often available in several depths. Orders ship from five US regional warehouses; for mixed or recurring orders use the bulk quote path with SKU, quantity and destination ZIP.

Related collections

From lightweight ECT-32 single wall for everyday parcels to heavier grades for dense loads. Every box lists its wall construction and certificate class on the product page.

Buying path

Buy Corrugated Boxes by the specs that change the order

Use filters, product titles, and product pages to compare size, material, pack count, case quantity, and fit before ordering.

Compare

Use filters and product titles to narrow by the specs that affect fit.

Confirm

Open the product page before ordering a case so you can check quantity, unit, and limits.

Reorder

Save the SKU or product link for repeat purchasing and support questions.

Larger orders

For pallet, recurring, or mixed-SKU needs, send support the details before placing a large order.

What to check first

  • Inside dimensions
  • Board grade or strength rating
  • Box style and closure
  • Case or bundle quantity
Common wrong-order risk: Choosing the outside size instead of the inside size. Confirm product fit, void fill, and storage space before ordering.
