A Procurement Manager's Checklist for Buying Corrugated Boxes

Buying corrugated packaging looks straightforward until something goes wrong on the shop floor or in transit, at which point it becomes clear how many decisions were left undocumented at the time of order. A written checklist, used consistently for every new supplier or new box design, closes most of the gaps that cause disputes later.

The checklist below is organised in the order these questions typically arise during a procurement cycle in an Indian manufacturing or distribution business.

The checklist

• Internal dimensions confirmed against the actual product, including any inserts or dividers
• Wall construction (ply and flute combination) specified and agreed in writing
• Bursting strength and edge crush test values stated on the specification sheet
• GSM of each paper layer confirmed, not just the overall board grade
• Print requirement, colours and panel positions finalised before plate-making
• Sample approved physically, not only on a drawing or PDF
• Test certificate requested for the production batch, not only the sample
• Supplier's monthly production capacity checked against your peak-month requirement
• Lead time for first order and for repeat orders both confirmed
• Storage conditions at your end reviewed for humidity and stacking height
• Escalation contact and response time agreed for quality issues
• Payment terms, minimum order quantity and price validity period documented

Specification and testing

Specification is the single most important item on this list because everything else, including price, is only meaningful in relation to it. Insist that ply, flute, GSM and target bursting strength or edge crush value are written down, not described verbally as heavy duty or export grade. Ask for the batch test report each time, since board quality can drift between production runs even from a reliable supplier.

Capacity and lead time

A supplier who quotes well but cannot handle your peak-season volume will cost you more in expedited alternatives than any saving on rate. Ask directly what percentage of their monthly capacity your order would represent, and what happens to your lead time if they take on another large customer.

Storage and escalation

Boxes lose strength in humid storage, which is a particular concern in coastal cities like Chennai during the monsoon months. Confirm how stock should be stored on your side, and separately agree who to contact, and within what time, if a delivered batch fails inspection.

Commercial terms

Finally, get minimum order quantity, price validity and payment terms in writing before the first purchase order, not after a dispute arises. A supplier of 50 years' standing should have no difficulty putting all of this on paper.
