As a cost analyst specializing in wholesale jewelry packaging supplies, I am often asked: “Why do quotes from different factories vary so much?” To answer this, you need to understand the cost components behind each price tag. Below, I break down the cost structure – from materials to sea freight – step by step.
Materials typically account for 30–50% of total production cost.
Greyboard forms the rigid structure of boxes like ring cases. Common thicknesses: 1.5mm, 2.0mm, 2.5mm, 3.0mm. A 0.5mm increase raises material cost by roughly 15–20%.
Illustrative price range (current market): 1.5mm greyboard ~$0.12–0.18/unit; 2.5mm greyboard ~$0.22–0.35/unit.
Cover paper is the “jacket” of the box. Options: coated paper (gloss/matte), specialty paper, soft-touch paper, PU leather.
Lining touches the jewelry and defines the perceived quality.
Processes turn a basic box into a branded masterpiece – and create the biggest quote differences.
CMYK 4-color is the base. Each spot color (e.g., Pantone 877C silver) adds ~$0.03–0.07/unit for small batches.

Small logo (<5cm²): ~$0.02–0.04/unit; large area (>50cm²): ~$0.22–0.45/unit.
Foil plate fee (~$20–45 per plate) is amortized separately.
Standard square box die: $30–60. Complex shapes (heart, petal): $120–220. Die-cutting labor for irregular shapes is 30–50% higher.
One-time fees (printing plates, die-cutting tools) are the main reason unit price drops with larger orders.
Regarding sampling fees: If you paid a separate sample fee that is not refundable (e.g., order below 2,000 units), that sampling cost is not amortized into the bulk order. If the sample fee is later refunded, it is effectively waived. The amortization below only includes plate and tooling fees.
Unit price = [(Material+Process) × Quantity + One-time fees] / Quantity
Assume: plates + tooling = $120 total. Material+process = $0.45/unit.
→ 10x quantity → unit price drops ~31%.
Freight is often the hidden assassin. The following are illustrative rates based on recent logistics.
International couriers/air freight charge the greater of actual weight and dimensional weight (DIM).
DIM weight (kg) = Length×Width×Height (cm) / 5000
Example: a box 30×20×10cm, actual 0.5kg → DIM = 1.2kg → chargeable = 1.2kg.
Cost-saving tip: Flat-pack (collapsible) boxes reduce DIM weight by >60%. Drawstring bags can be flattened to near-zero volume.
Assumptions:
| Cost Component | Per Unit ($) | Total ($) | Share |
|---|---|---|---|
| Greyboard + paper + lining | 0.30 | 300 | 34% |
| Printing + foil | 0.17 | 170 | 19% |
| Assembly labor + glue | 0.11 | 110 | 12% |
| Tooling amortization ($115/1000) | 0.115 | 115 | 13% |
| Inner box + outer carton | 0.07 | 70 | 8% |
| Factory profit + overhead | 0.085 | 85 | 10% |
| Ex-works total | 0.85 | 850 | 100% |
Freight not included. Example: LCL to US West Coast, 200 boxes per carton, volume ~0.2 CBM, freight ~0.2×$120 = $24, add $0.12/unit (~$0.85). Landed cost ~$0.97/unit.
Since every cardboard jewelry packaging project differs in size, process, and quantity, the example above is for illustration only.

Understanding the cost structure of wholesale jewelry supplies boxes helps you see why 1,000 units and 5,000 units have very different unit prices, and which factory's quote is more realistic. All prices in this article are illustrative; request a formal quote for your specific needs.
When you request quotes, always provide the complete checklist above and ask suppliers to list one-time fees (plates, tooling) separately – then you can verify the math yourself. Remember, the lowest ex-works price is not always the lowest landed cost – include freight and amortization in your comparison.
I hope this breakdown helps you source with confidence. For any questions, submit your requirements via our Customized Services page.
