What to Ask Before Ordering Custom Packaging: A Complete Buyer's Checklist

Custom packaging is a made-to-order product. Once production begins — and certainly once artwork is approved — changes become increasingly expensive and disruptive. The time to ask questions, clarify specifications, and confirm commercial terms is before committing, not after.

For first-time buyers, the unknown unknowns are the biggest risk. Not asking about home versus industrial compostable certification means you might receive packaging that does not match what your customers can do with it. Not confirming 3PL compatibility means discovering a dimension conflict after production. Not asking about lead time means planning for stock arrival three weeks earlier than reality allows.

This checklist covers three categories: specification, certification, and commercial. For the full production process overview, see the How Custom Compostable Mailers Work guide. For MOQ and volume readiness, see the What MOQ Means in Custom Packaging guide. This article also links from the enquiry funnel as a 'still researching?' resource — so it is designed to answer the questions buyers most often have before they are ready to commit.

Start with the material itself. 'Compostable mailer' describes a category, not a specific material. The construction — which bio-based polymers, what thickness, what print method — affects performance, certification, and what the mailer can claim. Ask for internal dimensions, not external — internal dimensions determine whether your product fits. Ask about closure type: single adhesive strip or double-strip (for returns reuse). Ask about transit performance: moisture resistance, puncture resistance, seal strength at your product weight range.

Ask for the specific compostability certification — the standard (AS5810, AS4736, EN 13432, ASTM D6400), the certifying body (ABAP, TÜV Austria, DIN CERTCO, BPI), a certificate number, and an expiry date. Ask whether it is home compostable or industrial compostable — this determines what disposal guidance you can give customers. Ask what disposal instructions you should put on the packaging, and whether there are regional infrastructure differences to consider for the markets you sell into.

Ask for tiered pricing across MOQ thresholds — not just the minimum run price. The difference between 2,000 and 10,000 units is often significant and affects your order size decision. Ask about lead time from artwork approval (not from enquiry date), and what happens to the timeline if artwork approval is delayed on your side. Ask about payment terms — deposit and balance structure. Ask whether the quoted price is ex-works or delivered.

A common mistake in custom packaging procurement is comparing quotes without confirming that each quote covers the same scope. The per-unit price is only part of the total cost — and it is often the part that obscures the biggest differences between suppliers.

Before comparing quotes, confirm for each supplier whether the price includes: freight from the manufacturing facility to your warehouse (ex-works vs delivered); design or artwork support (some suppliers charge separately, some do not); certification documentation (included or at additional cost); and any import duties or customs fees applicable to your delivery country. A delivered price that includes design support and certification documentation from a supplier with clearly referenced certifications may represent better total value than a lower unit price that excludes all of these.

The same caveat applies to lead time comparisons. A supplier quoting 6 weeks may be measuring from enquiry; another quoting 10 weeks may be measuring from artwork approval. Align the measurement before comparing.

Estimates are enough to begin — you do not need finalised artwork or exact dimensions. What helps is a clear picture of your product range, dispatch volume, timeline, and print intent. Useful information: your website URL or brand references; approximate internal dimensions based on your most common products; estimated monthly dispatch volume; print direction; delivery country; required-by date. If you use a 3PL, mention it.

Useful files: vector logo if available (.ai, .eps, PDF), or a high-resolution PNG/JPG as a starting point; Pantone or HEX colour references; any brand guidelines. Zero Pack offers free design support. The starting point is the custom compostable mailers enquiry page.
