Custom Shipping Boxes
Custom shipping boxes are fluted corrugated cartons built to protect e-commerce orders, subscription kits, and wholesale cases through UPS, FedEx, and USPS transit. Choose Regular Slotted Containers (RSC), die-cut boxes, or double-wall cartons on brown or white corrugated board. Ready in 10–14 business days (rush 4–5) with free US shipping.
What are custom shipping boxes?
Custom shipping boxes are heavy-duty fluted corrugated containers engineered to carry single e-commerce orders, multi-item subscription kits, food deliveries, apparel, kitchenware, and industrial goods safely through parcel carriers and palletized LTL freight. The flagship construction is the Regular Slotted Container (RSC, FEFCO code 0201), where four top flaps and four bottom flaps of equal depth fold inward so the two lengthwise outer major flaps meet at the center seam to be sealed with packing tape. Because every wall is built from an arched fluted medium sandwiched between two linerboards, corrugated shipping boxes absorb drop impacts and resist vertical warehouse stacking loads while reducing dimensional (DIM) weight charges when sized to your exact product. Depending on payload weight and unboxing style, you can specify single-wall B-flute or C-flute RSC cartons, self-locking die-cut corrugated boxes, or heavy-duty double-wall cartons.
Which styles are in the custom shipping boxes group?
Match your parcel weight, fulfillment packing speed, and customer unboxing experience to the right corrugated shipping structure in our family: Whether your team calls them corrugated shipping boxes with logo, regular slotted container rsc boxes, branded shipping cartons wholesale, shipping boxes with logo, branded shipping boxes, wholesale shipping boxes or bulk custom shipping boxes, every sheet is cut to your exact inside dimensions.

What are the most common mistakes when ordering custom shipping boxes?
Avoid these five structural and prepress errors before sending your corrugated shipping boxes to production. For buyers ordering personalized shipping boxes, custom size shipping boxes, shipping boxes with outer major flaps or shipping boxes with inner minor flaps, watch out for these common sizing and artwork mistakes
- Leaving 2 to 4 inches of empty head space above the product, which inflates carrier dimensional (DIM) weight fees and allows the top flaps to cave in when heavy parcels are stacked on top in a delivery truck.
- Placing your main logo or headline right across the center seam of the top flaps, where 3-inch packing tape or a 4 × 6 inch thermal shipping label will cover it completely.
- Packing 35+ lb of glass bottles, Liquids, or metal parts inside a standard single-wall 32 ECT carton instead of upgrading to 44 ECT single-wall or 48 ECT BC double-wall corrugated board.
- Orienting the box so the corrugated flutes run horizontally instead of vertically along the Height (H) axis, which cuts top-to-bottom stacking compression strength by more than 40%.
- Sealing heavy 25+ lb RSC boxes with a single strip of thin plastic tape instead of water-activated reinforced paper tape applied in an H-tape pattern across both center and edge seams.

What is a Regular Slotted Container (RSC) shipping box?
A Regular Slotted Container (RSC, FEFCO code 0201) is the world's standard corrugated shipping box. All four top flaps and four bottom flaps are cut to the same length (half the container's Width) so the two outer lengthwise major flaps meet edge-to-edge in the center to be sealed with tape.
What is the difference between a shipping box and a mailer box?
A shipping box (RSC) has four top and four bottom flaps that seal with tape and is optimized for the lowest cost per cubic inch and highest stacking strength from 5 to 80+ lb. A mailer box (RETF) is a one-piece die-cut corrugated box with a hinged lid and locking front ears that closes without tape for gift-like DTC unboxing.
Should I choose B-flute, C-flute, or double-wall corrugated board?
Choose B-flute (1/8 in thick) for compact-to-medium e-commerce boxes under 25 lb that need a flatter printing surface and higher puncture resistance; C-flute (5/32 in thick, 32–44 ECT) for general-purpose shipping boxes up to 40–50 lb; and BC double-wall (9/32 in thick, 48+ ECT) for heavy, fragile, or stacked shipments up to 80–100+ lb.
How do I measure Length, Width, and Height for a shipping box?
Always provide the usable interior dimensions in Length × Width × Height (L × W × H) order: Length (L) is the longer horizontal opening dimension, Width (W) is the shorter horizontal opening dimension, and Height (H) is the vertical depth from the bottom flaps to the top flaps.
Can you print on both the outside and inside of a custom shipping box?
Yes. You can print a clean 1-color or 2-color logo on the natural kraft exterior for security and carrier branding, and print a full-color flood coat, pattern, or QR code message across the inside top flaps and inner walls.
Can you make custom corrugated dividers or foam inserts for glass bottles and jars?
Yes. Select Card insert, Honeycomb insert, or EPE foam insert in Step 2 of the quote form. Our packaging specialists design interlocking 4-, 6-, or 12-cell corrugated partitions or die-cut foam pads sized to your exact shipping box.
What is the minimum order quantity for custom shipping boxes?
In the quote form you can select preset quantities starting at 250, 500, 1,000, 2,500, or 5,000+ boxes, and trial orders are reviewed case by case.
How do custom-sized shipping boxes lower my UPS and FedEx shipping costs?
Major carriers charge by dimensional (DIM) weight whenever a box's cubic volume (L × W × H ÷ 139) exceeds its actual scale weight. Eliminating 2 to 3 inches of empty air with a custom-sized RSC box can drop your parcel by 1 to 3 billable pounds per shipment.
How long does production take for custom printed shipping boxes?
Standard production takes 10–14 business days after you approve your 2D dieline and 3D digital proof and complete payment. Rush production in 4–5 business days is available for urgent restocks.
How are custom shipping boxes delivered?
All custom shipping boxes ship knocked-down flat (KDF) with the vertical manufacturer's side joint pre-glued, strapped in bundles or stacked on pallets, with free delivery to all 50 US states.
