How to Compare Magnetic Box Quotes

How to Compare Magnetic Box Quotes: A Line-by-Line Method

Two quotations for the same magnetic box can differ by 30% without either supplier being wrong — the difference is almost always in unstated assumptions. This guide covers where those assumptions hide, how to normalise a specification before comparing, how to separate one-off tooling from recurring cost, and the checklist to put every quote on the same page.

Why Two Quotes for the Same Box Differ

Two suppliers looking at the same artwork will rarely return the same number, and it is not usually because one is padding the price. The unit price of a magnetic box is assembled from board, wrap, magnets, insert, finishing, labour and packing. Suppliers make different default assumptions about almost every one of those.

Table 1: Seven main sources of quotation divergence — align each item before you can truly compare prices.

Step 1: Normalise the Specification

Write one specification and send it to every supplier verbatim. If the spec changes between requests — even subtly — the replies are not comparable.

The last item is the one most often skipped, and it changes the picture. A quote built on a 5,000-piece assumption is not comparable with one built on 500 — tooling amortisation behaves completely differently across those two quantities.

Step 2: Decompose the Unit Price

Ask each supplier to break the unit price down. Most will, and the ones that refuse are telling you something. A decomposed quote lets you see which line actually differs rather than just the total.

Table 2: Check the quotation line by line — locate the difference to a specific line, rather than stopping at the total price gap.

Step 3: Separate One-off and Recurring Costs

Unit price is only meaningful once you know which costs occur once and which occur every time you reorder. A supplier offering a lower unit price with tooling amortised into it is not necessarily cheaper — you may be paying for tooling twice if development changes.

• One-off: die-cut tooling, cutting forme, printing plates or screens, embossing or foil dies, mould or tooling for a custom insert.
• Recurring: materials, magnets, printing, finishing, assembly labour, packing, inbound freight.
• Conditional: tooling often waived or credited above a stated MOQ — get that threshold in writing.

Step 4: Compare Total Landed Cost

Unit price ex-works is not the number you pay. For an export programme the difference between two suppliers often sits entirely in freight, defects and reorders.

Table 3: Five variables of landed cost — not visible on the quotation, but they determine actual spend.

Red Flags in a Magnetic Box Quote

1. Magnet specification absent. Generic “magnetic closure” with no grade or dimension — you cannot verify what you are buying.
2. Tooling omitted entirely. Usually means it is coming later, or is buried in the unit price.
3. No tolerance stated on any dimension — including internal clearance.
4. Single-line unit price with no component breakdown available on request.
5. No mention of the insert material or density despite a heavy product.
6. Sample lead time quoted but not production lead time, or vice versa.
7. Price valid indefinitely. Paper and magnet prices move; a quote with no validity window is a guess.

Comparison Checklist

Put every quote into the same table before comparing totals. Anything you cannot fill in for all suppliers is a question still to ask.

Once all of that is on one page, the cheaper supplier is usually obvious — and it is frequently not the one that looked cheapest in the first email.

Conclusion

Comparing magnetic box quotes is a normalisation exercise before it is a negotiation. Send one identical specification, decompose every unit price, separate one-off tooling from recurring cost, and fold in freight and defect exposure. The comparison table above also doubles as your RFQ — sending it upfront usually eliminates a round of clarification emails.

The comparison method described here applies to general rigid magnetic-box projects; specific terms (mould ownership, reorder threshold, quotation validity) should be confirmed in writing with the supplier.
