Specification FAQs
Is ΔE ≤ 2 color accuracy guaranteed for every batch?
Yes. Every production batch is measured against the approved proof with professional color management, and batch-to-batch variation is kept at ΔE ≤ 2. This applies to both CMYK process colors and Pantone spot colors.
What does the ± 0.5 mm tolerance cover?
Die-cut box dimensions (length, width, height) and insert fit. Precision die-cutting keeps all panels within ± 0.5 mm of the approved dieline, which keeps lids closing smoothly and inserts holding products firmly.
Is the MOQ really 500 pieces?
Yes — 500 pcs per design and style, with no hidden small-batch surcharges. For mixed sizes or styles within one order, confirm the split with our team for your specific structure.
How fast can I get a physical sample?
Standard structures are sampled in 3–5 working days; structures with foil stamping, embossing or custom inserts take up to 8 days after the digital proof is approved.
Which certifications do you hold?
ISO 9001:2015 for quality management, FSC Chain of Custody for paper sourcing, SEDEX SMETA for ethical audit, plus RoHS and CE test reports — the certification set most US and EU retailers require.
