How to Ship Graded Cards Safely (Slabs That Arrive Intact)
A step-by-step guide to shipping graded cards and slabs safely — packaging, padding, insurance, and how to avoid cracked cases in transit.
Shipping a graded card safely comes down to immobilizing the slab, padding it against impact, and insuring it for its value. A cracked case in transit can drop the card's value even if the card itself survives.
Quick answer
To ship a graded card: wrap the slab in bubble wrap, sandwich it between two pieces of cardboard or in a slab-specific box, place it in a bubble mailer or small box, and add tracking plus insurance for the card's value. For high-value slabs, use a rigid box, not just a mailer.
What you'll need
- Bubble wrap or foam sleeves
- A slab box or two rigid cardboard pieces
- Painter's or packing tape
- A bubble mailer (low value) or small rigid box (high value)
- Tracking + insurance (and signature confirmation for high value)
Step-by-step
- Sleeve check — confirm the slab is intact and clean before packing.
- Wrap the slab in 2–3 layers of bubble wrap, taping it closed.
- Immobilize it — the slab must not slide or rattle inside the package.
- Add rigid protection — a slab box or cardboard sandwich prevents flexing.
- Box or mail it — bubble mailer for inexpensive slabs, rigid box for valuable ones.
- Seal and label — tape all seams; avoid writing "cards" on the outside.
- Add tracking and insurance — match coverage to the card's value.
Value-based shipping tiers
| Card value | Recommended method |
|---|---|
| Under $50 | Bubble mailer, tracking |
| $50–$500 | Rigid box, tracking + insurance |
| $500+ | Rigid box, insurance, signature confirmation |
| $5,000+ | Insured courier, consider third-party shipping insurance |
Common mistakes
- Shipping a slab loose in a too-big box (it bounces and cracks).
- Skipping insurance to save a few dollars.
- Using only a plain envelope — slabs need rigid protection.
