Twelve questions, answered properly.

Including the two we get asked most often and most sceptically: how many times a box can really be reused, and why there is no phone number anywhere on this website.

A USEFUL SHORTCUT

Not sure of the size?

Fold a box in the browser, read off the cube and pallet fit, and send the spec straight through.

What is a gaylord box, exactly?

A gaylord is a large, usually triple-wall corrugated bulk container sized to sit on a standard 48" × 40" GMA pallet. The name comes from the Gaylord Container Corporation, which popularised them — it is a brand name that became a generic term, like dumpster. Typical capacity is 1,800 – 2,200 lb and around 40 cubic feet.

Do you really sell used boxes, or refurbished ones?

Both, and we are explicit about which. Grade A and B boxes are used as-is after inspection. Reconditioned boxes have had flaps spliced, panels patched or scores rebuilt at our bench, and are re-graded afterwards. Every quote states which you are getting.

What is your minimum order?

One pallet for gaylords (typically 20 – 24 knocked-down boxes). For RSC shippers, 250 boxes or a mixed pallet. Below that we will usually point you to a local supplier rather than charge you freight that makes no sense.

How do you price used boxes?

Grade, size run, volume and lane. A matched run of 2,000 grade-B 18" cubes prices very differently from 2,000 mixed boxes of random sizes, because sorting is the expensive part. We quote delivered, with the freight shown separately.

Will you buy boxes from us?

Yes — clean used corrugated and gaylords. Send a photograph of the stack and a rough count. We price by grade and volume, bring our own trailer, and pay on pickup or net-7. We will also tell you honestly when baling will pay you more than resale.

Do you ship outside Missouri?

Routinely, to all fifty states. Our core freight lanes cover the Midwest and Mid-South within a day's drive of St. Louis, and we ship full truckloads nationwide. See the locations pages for zone, transit time and mode by state.

Can used boxes be used for food?

Direct food contact, no — not from a used container, and no certificate changes that. But lined used gaylords are used widely in produce and agriculture, with an FDA-compliant poly or foil liner between product and board. We supply the liners and the supplier letters of guarantee.

What happens to boxes that are too damaged to resell?

There is a hierarchy: repair, then dunnage, then honeycomb panel, then upcycled goods, then mill-spec baled OCC. Only wax-coated and contaminated board becomes genuine residual, and we report that fraction rather than hiding it.

How many times can a box be reused?

Our marked-container data gives a median of nine round trips for triple-wall gaylords, with a top decile of fourteen. The limiting factor is almost always handling, not board quality. We wrote this up in detail on the blog.

Do you offer printed or branded used boxes?

We can blank out existing print and apply a single-colour mark on recovered board. For multi-colour brand work, a new box with high recycled content is usually the better answer, and we will say so.

Can we get diversion reporting for our sustainability team?

Yes. Monthly or quarterly statements covering tonnage reused, tonnage recycled, landfill avoided and estimated CO₂e avoided, with our assumptions attached so your team can audit them.

Why do you not list a phone number?

Everything we do involves dimensions, grades and counts, and those get mangled over the phone. Email and the form give us the detail we need to quote accurately the first time, and give you a written record. We reply within one business day.

What is the difference between ECT and Mullen?

They measure different things. Mullen is a bursting test in pounds per square inch and predicts puncture resistance. ECT is an edge crush test in pounds per linear inch and predicts stacking strength. In a palletised supply chain ECT is almost always the number that matters. Conversion tables between them are rules of thumb, not physics.

Does a used box still meet its printed certificate?

No. The Box Maker's Certificate describes the board as it left the converter. A used container has been loaded, stacked, trucked and cycled through humidity changes; the flutes have taken a set and the scores have softened. We grade on observed condition instead and say so on every quote.

How do you measure a box?

Length × width × height, always inside dimensions. Length is the longer side of the open face, width the shorter, and height is measured down from the open face. Outside dimensions add roughly 1/8" per wall for single, 5/16" for double and 5/8" for triple — on every axis, both sides.

What is the difference between knocked down and erected?

Knocked down means shipped flat. A flat 48 × 40 × 36 gaylord occupies about 4.7 cubic feet against 40 erected, so a trailer carries 534 instead of 62. Unless your receiving dock genuinely cannot erect a box, knocked down wins by a margin nothing else on the invoice can close.

Do you sell lids and liners separately?

Yes, and we push them harder than most suppliers because they are the cheapest life extension available. A separate telescoping cap adds two to three trips to a container on our own marked-container data.

What is OCC?

Old Corrugated Containers — the recycling commodity grade for used cardboard. Mill grades #11 and #12 under the ISRI specification are the usual targets. #12 is double-sorted and cleaner, and carries a premium.

How quickly do you reply?

Within one business day, every business day. Enquiries go to a grader on the floor rather than to a general inbox, so the reply usually contains an actual number rather than a request for a call.

Can we visit the yard?

Yes. Monday to Thursday, 9:00 AM to 3:00 PM Central, at 9869 Meeks Blvd. Bring safety shoes. We would much rather you looked at the grading stations yourself than took our word for the scale.

Do you offer a managed container pool?

Yes — collection, grading, reconditioning, storage, re-issue and quarterly reporting under one contract. Your containers stay yours; we just keep them circulating. The metric we report on is trips per container per year.

How big should a container pool be?

Peak weekly demand multiplied by cycle time in weeks, plus 20% slack. Undersized pools generate emergency purchases of new containers, which is how a reuse programme ends up buying virgin board.

What payment terms do you offer?

Sales: net-30 on approved accounts, otherwise payment before dispatch. Purchases from you: on pickup or net-7, agreed before collection. We do not do 'we will tell you what it made at the mill'.

What if the delivery is short?

Up to 5% we credit on your word, without inspection. Above that we investigate, which may include collecting the pallet. Arguing about twelve boxes costs more than twelve boxes.

Can you match a competitor's price?

Sometimes, but ask what grade they named first. 'Used' on its own covers everything from a box that shipped once to one that has been rained on for a winter, and a price without a named grade is not a quote.

Do you handle hazardous or regulated material?

No. We cannot accept containers carrying hazardous-material markings, and we will not remove them. It is a regulatory matter rather than a judgement call.

What is the lead time on new or custom boxes?

Stock sizes ship from inventory. Custom dies run 10 – 15 working days, with 1 – 4 colour flexo print. We will tell you when a grade-A used box would do the same job for a third of the price.

What recycled content do your new boxes have?

Most US-made board runs 70 – 90% post-consumer recycled content as standard. Up to 100% recycled test liner is available on request, with the caveat that very high recycled content slightly reduces burst strength for a given basis weight.

Do you provide carbon figures for our reporting?

Yes, with every coefficient published so you can substitute your own. We use 1.30 kg CO₂e per kg for virgin corrugated and 0.215 kg per kg for a reuse cycle, and we deliberately exclude end-of-life recycling credit, stored fibre carbon and avoided landfill methane — all three would flatter the number.

What is your contamination rate?

Around 1.9% on baled OCC in a normal quarter. It rose to 3.4% for two quarters in 2023 after we underestimated a customer's waste stream, and we published that in the same statement as the good numbers. A figure you only share when it flatters you is marketing.

Can I specify my own grading standard?

Yes, and several pooled customers do. We will grade to your written standard and report against it. It costs slightly more because it breaks our batching, and we will tell you how much before you commit.

What is the biggest mistake buyers make?

Quoting outside dimensions as inside. A 48-inch outside triple-wall box has a 46.75-inch inside dimension, and nobody discovers the difference until a trailer arrives. Second place: specifying flush to the 48-inch pallet standard when real GMA pallets run from 47.5 to 48.5 inches.

Still stuck?

Email reaches a person, not a queue.

One business day, every day. If it is technical, it goes to a grader; if it is commercial, it goes to the yard manager.

Why this page exists

Questions asked more than twice end up here

This page is maintained from the actual inbox rather than written as marketing copy, which is why some of the answers are longer and less flattering than a FAQ usually is. If a question gets asked a third time it goes on the list; if the answer gets long enough to deserve it, it becomes a blog post instead.

The two we get asked most sceptically

First: how many times can a box really be reused? The honest answer is a median of nine trips on marked triple-wall containers, with a spread from four to fourteen, and the difference is almost never the board — it is handling. We published the full study rather than a round number.

Second: why is there no phone number? Because dimensions, grades and counts get mangled in conversation and survive in writing. It is a deliberate decision that costs us some enquiries and prevents a specific, expensive failure mode we lived with for three years.

Lead times

How long each thing actually takes.

Measured from a confirmed order, not from the first email. Artwork approval and procurement onboarding sit outside these figures and are usually the real critical path.

Seven things about your dock that change the quote.

Declared before the quote these are free to plan around. Discovered on delivery day they are the single most common reason a cheap quote becomes an expensive invoice.

Why empty packaging rates so badly.

LTL pricing keys off density. Knocked-down corrugated weighs almost nothing and occupies a full pallet position, so it lands near the expensive end of a scale designed around weight.
