How to Get Quotes from Corrugated Box Manufacturers: What Information You Need

Getting accurate, comparable quotes from corrugated box manufacturers is both simpler and more nuanced than most buyers expect. Simple because the basic information needed is straightforward — dimensions, quantity, board grade, print. Nuanced because the details you provide (or fail to provide) directly affect both the pricing you receive and whether the quote actually matches your needs.

A vague or incomplete quote request gets a padded, estimated response. A precise, well-prepared request gets an accurate, competitive quote — and signals to the supplier that you're a serious buyer worth winning.

This guide covers exactly what information to prepare, how to structure your request, and how to compare responses from multiple manufacturers.

The Information Every Quote Requires

1. Box Dimensions (Inside Dimensions)

This is the most fundamental specification, and it's the one most often communicated incorrectly.

Always specify inside dimensions, not outside dimensions. Corrugated board has thickness — approximately 3/16" for standard C-flute single wall — and inside dimensions are what determine whether your product fits.

Dimensions are expressed as Length x Width x Height (Depth), where:

• Length — The longest opening dimension
• Width — The shorter opening dimension
• Height (Depth) — The distance from the opening to the bottom

Industry convention: Length x Width x Height, always in that order.

Common mistake: Providing outside dimensions (which are larger by twice the board thickness per dimension) or providing dimensions in a non-standard order. If there's any ambiguity, include a sketch or reference to a sample.

2. Box Style

The box style defines the structural design. Common styles include:

If you're unsure which style is best, describe how the box will be used and let the manufacturer recommend a style. A packaging engineer can suggest the most cost-effective design for your application.

3. Board Grade

Specify the corrugated board grade using one of these systems:

ECT (Edge Crush Test) — The modern standard:

• 32 ECT: Standard single wall (~40 lb capacity)
• 44 ECT: Heavy-duty single wall (~65 lb capacity)
• 48 ECT: Standard double wall (~80 lb capacity)
• 51-90 ECT: Heavy-duty double and triple wall

Mullen (Burst Test) — The older standard:

• 200# test: Roughly equivalent to 32 ECT
• 275# test: Roughly equivalent to 44 ECT

If you're unsure: Specify the product weight and how the boxes will be handled (stacking height, shipping method, etc.) and let the manufacturer recommend a board grade. Most will specify the lightest adequate board, which is in your economic interest.

For detailed guidance on board selection, see our guide on choosing the right corrugated box for your product.

4. Quantity (Multiple Levels)

Always request pricing at 2-3 quantity levels. This reveals the supplier's pricing curve and helps you determine the most economical order size.

Example:

• 1,000 units
• 2,500 units
• 5,000 units

Include your estimated annual volume even if you plan to order in smaller batches. This signals total potential business and may unlock better pricing or blanket order terms.

For context on how quantity affects pricing, see our guide on minimum order quantities.

5. Print Specifications

Printing is a major cost driver. Be specific:

No print (plain kraft):

• Cheapest option
• No setup charges for printing

1-color flexographic print:

• Specify ink color (PMS number preferred)
• Provide print area (what percentage of box surface is printed?)
• Provide artwork file (vector PDF or AI format)
• Note: Setup cost typically $150-$400 for the printing plate

Multi-color flexographic print:

• Number of colors
• PMS numbers for each color
• Registration requirements (do colors need to align precisely?)
• Artwork files
• Setup cost: $150-$400 per color

Full-color (process or digital):

• CMYK artwork at 300 DPI minimum
• Specify whether flexo (litho-lam) or digital print is acceptable
• Note significantly higher tooling costs for flexo; much lower for digital

6. Delivery Information

• Ship-to location (city/state minimum; full address preferred)
• Delivery timeline (when do you need the first order?)
• Delivery method preference (truck delivery, will-call pickup, LTL)
• Loading dock availability (yes/no — affects delivery method and cost)

7. Any Special Requirements

Note any of the following that apply:

• Food contact — Requires FDA-compliant materials
• Moisture resistance — Wax coating, curtain coating, or water-resistant treatments
• Temperature exposure — Freezer or cold chain applications
• Hazmat certification — UN-rated packaging for dangerous goods
• Retail-ready requirements — Specific retailer compliance needs
• Sustainability certifications — SFI, FSC chain of custody
• Testing requirements — ISTA, ASTM, or carrier-specific testing

Structuring Your Request for Quote (RFQ)

A well-organized RFQ gets faster, more accurate responses. Here's a template structure:

Company Information

• Company name and contact information
• Industry/product type
• Current annual corrugated spending (optional but helpful for the supplier to gauge the opportunity)

Item Details (Per Box Size)

For each box size requested:

Delivery Details

• Ship-to location(s)
• Required delivery date for first order
• Anticipated reorder frequency
• Loading dock (yes/no)

Quote Requirements

• Quote validity period requested (30-60 days is standard)
• Specify whether you want setup charges broken out separately
• Request lead time for initial order and reorders
• Request sample availability and timeline

Where to Send Your RFQ

Cast a wide enough net to get competitive pricing, but not so wide that you can't evaluate the responses thoughtfully. Three to five suppliers is typically the right number.

Finding Qualified Suppliers

• AICC Member Directory (aiccbox.org) — Independent corrugated converters searchable by location and capability
• Local search — "[Your city] corrugated box manufacturer" — proximity reduces freight costs
• Industry referrals — Ask business contacts in your industry who they use
• Trade shows — Pack Expo, AICC annual meeting, regional packaging shows
• Online suppliers — For smaller quantities and simpler boxes, online-first suppliers offer instant quoting

How to Read and Compare Quotes

Corrugated box quotes can be structured differently across suppliers, making apples-to-apples comparison tricky. Here's what to normalize:

Unit Price

The per-box cost. Make sure you're comparing the same quantity level — unit price at 2,500 units from Supplier A compared to 5,000 units from Supplier B isn't a valid comparison.

Setup and Tooling Charges

Some suppliers fold tooling into the unit price (especially for high quantities). Others break it out. When comparing, calculate the total cost for your order = (unit price x quantity) + tooling charges + freight.

Freight and Delivery

Quotes may or may not include delivery. Common approaches:

• FOB origin — You pay freight from the supplier's dock
• FOB destination / delivered — Freight is included in the price
• Prepaid and add — Supplier arranges freight and adds it to the invoice

Always compare on a delivered cost basis. A supplier 500 miles away with a lower box price may cost more delivered than a local supplier with a higher box price.

Overrun/Underrun Terms

Standard industry practice allows the manufacturer to deliver +/- 10% of the ordered quantity. You're obligated to accept and pay for the actual quantity delivered within this range.

This matters for cost planning: an order for 2,000 boxes could result in an invoice for 2,200 boxes. Budget for the overrun possibility.

Lead Times

Compare lead times for:

• Initial order (includes tooling manufacturing) — typically 2-4 weeks
• Reorder (tooling already exists) — typically 5-10 business days
• Rush capability — can the supplier expedite if needed, and at what cost?

Common Quote Request Mistakes

Requesting too many quantity levels. Stick to 2-3. Asking for 8 quantity levels from 100 to 100,000 wastes the supplier's quoting team's time and signals that you're not serious about any specific volume.

Omitting print specifications. "We might want some printing" is not a spec. If you're considering printing, specify the number of colors and provide artwork. If you haven't finalized the design, get a quote for both printed and unprinted to understand the cost difference.

Using outside dimensions. This is so common that many experienced corrugated salespeople will ask to clarify. Save everyone time by specifying "Inside Dimensions" explicitly.

Not specifying delivery location. Freight can be 15-25% of the total cost. A quote without delivery terms is incomplete.

Comparing quotes from different time periods. Corrugated pricing moves with the containerboard market. Quotes received three months apart may reflect different raw material costs. Request all quotes within the same 2-week window.

Focusing only on unit price. The cheapest per-unit price with a $2,000 die charge, 4-week lead time, and 5,000-unit minimum may cost more than a slightly higher per-unit price with no tooling, 1-week lead time, and 500-unit minimum. Compare total cost of ownership.

After You Receive Quotes

Normalize to Total Cost

Create a comparison spreadsheet:

Request Samples

Before committing to a large order, request samples from your top 2 candidates. Evaluate:

• Dimensional accuracy (measure with calipers)
• Board caliper and rigidity
• Print quality and color accuracy
• Fold and score cleanliness
• Glue joints (clean, full coverage, properly aligned)

Negotiate Strategically

With competitive quotes in hand:

• Lead with volume, not just price — Suppliers are more willing to sharpen pricing for committed volume
• Offer longer-term commitments — Annual contracts unlock better pricing than spot orders
• Ask about cost-reduction engineering — A good supplier will help you optimize specs to reduce cost; see our guide on reducing corrugated packaging costs
• Discuss payment terms — Early payment discounts (2% net 10) can offset per-unit price differences

The Bottom Line

Getting good corrugated box quotes starts with providing good information. Complete, precise RFQs produce accurate, competitive quotes — and earn you credibility with suppliers who prioritize serious buyers. Prepare your dimensions (inside), quantities (2-3 levels), board grade, print specs, and delivery requirements before reaching out, and you'll be well positioned to make an informed purchasing decision.
