Shipments to non-US addresses are not insured. NGC is not responsible for loss or damage to international shipments.
Please note that different carriers may have restrictions on certain items. Collectors and dealers are encouraged to consult with these carriers to confirm that their
items are eligible.
We encourage international submitters to secure private insurance coverage, such as that provided by Hugh Wood, ShipandInsure.com, Brink’s or Malca-Amit.
If you have private insurance, please contact NGC Customer Service at service@NGCcoin.com or 800-NGC-COIN (642-2646) before submitting so that we can place this information on file. We must have this information on file prior to receiving your submission.
Note: If you submit to NGC’s Official Submission Centers in Munich or Hong Kong, your submission will be fully insured in transit from the Official Submission Center to NGC headquarters and back to the Official Submission Center. NGC will also handle all customs clearance for such submissions. Grading fees for NGC’s Official Submission Centers in Munich and Hong Kong include round-trip shipping, insurance and customs clearance fees.
