International Shipping From the Tucson Gem Shows (2027)

2026-10-15

Shipping gem show purchases abroad: customs form rules, the $2,500 export filing (EEI) threshold, Canada exemption, rough diamond Kimberley Process rules and the new EU low-value import rules.

TucsonGemShow101 says the shows draw attendees from Europe, Japan, China and Africa as well as the U.S. Here's what applies when your purchases leave the U.S. Rules were checked on Oct 15, 2026. This isn't legal or customs advice, so confirm with your carrier or a customs broker for big shipments.

1. Every package needs a customs form

USPS says you need a customs form for everything you send abroad, except First-Class Mail International letters and large envelopes under 15.994 oz that hold only documents.

  • Describe each item specifically: what it is, what it's made of, and what it's for. USPS now requires detailed descriptions, and says vague entries like "gifts" or "tools" aren't acceptable. For gem show buys, something like "polished quartz mineral specimen" or "loose cut sapphires" is the kind of detail it's asking for.
  • Give each item its own value, plus a total for the package, and the gross weight.
  • Don't abbreviate sender or recipient names and addresses.
  • If the form is wrong, USPS warns the destination country may return, discard or destroy the package.
  • You can print the form with Click-N-Ship (Priority Mail International, Priority Mail Express International, First-Class Package International) or fill out PS Form 2976-R at the Post Office.

2. Export filing (EEI) over $2,500 per item type

The International Trade Administration says you must file Electronic Export Information (EEI) in the Automated Export System when the value of goods under any single Schedule B number is over $2,500, or when an export license is needed.

  • The $2,500 test is per Schedule B number, not per package total.
  • Shipments to Canada don't need EEI, unless a license or other mandatory filing applies.
  • If you mail through USPS, you give the post office the filing number (ITN) or the exemption citation.
  • Look up Schedule B numbers on the Census Bureau's Schedule B site, or call the Census Bureau at 1-800-549-0595, option 2.

Big wholesale buys can easily pass $2,500 in one category, so check this before you pack.

3. Rough diamonds need a Kimberley Process certificate

The State Department says the Kimberley Process requires rough diamonds to be shipped in tamper-proof containers with a Kimberley Process Certificate, and prohibits trade with non-participant countries. U.S. exporters get certificates from the U.S. Kimberley Process Authority. CBP publishes the U.S. export procedures. The scheme is about rough (uncut) diamonds. Talk to your vendor and carrier before you try to ship rough.

4. Shipping to the EU: new low-value rules

USPS says that starting July 1, 2026, packages with merchandise valued up to €150 going to countries that follow EU customs rules may face new import duties and requirements. Expect the recipient side to ask more questions, and describe items carefully.

5. Where to ship from

TucsonGemShow101 says UPS and DHL have stations at several high-volume venues offering international shipping and packing materials. The Tucson post office and The UPS Store are in our Ship & Store listings. Ask vendors too, since some ship internationally for their buyers.

Checklist

  1. List every item with a specific description and value.
  2. Add up the value by item type. Anything over $2,500 per Schedule B number needs EEI (except to Canada).
  3. Rough diamonds: Kimberley Process certificate first.
  4. Keep receipts and photos with your paperwork.
  5. For heavy lots, see freight and pallet shipping and how to ship rocks home.
