Do you need paperwork or pay duty to import minerals and crystals?

Yes, every commercial import goes through U.S. Customs and Border Protection (CBP), and the duty depends on how the goods are classified in the Harmonized Tariff Schedule (HTS). Many rough minerals and unworked stones are classified at a free general rate, but the heading matters: in a 2021 notice CBP proposed moving calcite, aragonite, selenite and amber out of the "collectors' pieces" heading 9705 into headings for stones and minerals, and worked amber into a heading with a 2.7 percent rate [1]. Additional country-specific duties can also apply. This page explains how classification works for specimens, what that notice shows, and the other paperwork questions an importer meets.

How customs sees a mineral

To CBP, a box of stones is goods to be classified, valued and, where required, marked with its country of origin. The classification decides the duty rate and any special rules. For minerals the choice is usually among a few chapters of the HTS:

The general rates above come from the rulings discussed in that notice and are not a complete or current duty table. Rates for other goods, polished and carved stones, and goods from particular countries can differ, and additional duties on imports from specific countries have changed often. Look up the current HTS for each item, or have a licensed customs broker do it, before you price imported stock.

What the 2021 CBP notice shows

The notice in CBP's Customs Bulletin and Decisions, Volume 55, No. 15 (April 21, 2021), proposed revoking four earlier rulings that had classified mineral stones as collectors' pieces under heading 9705 [1]. The reasoning is useful for anyone importing minerals:

• Common material is not a collectors' piece. CBP said amber is generally common and lacks the rarity heading 9705 requires, and that gypsum is abundant and not considered rare unless gem-quality and transparent; the selenite stones in question were neither colorless nor transparent [1].
• Chapter 71 comes first for listed stones. Because the Chapter 71 annex lists calcite and aragonite as semiprecious stones, CBP said calcite geodes fall in heading 7103, and that even rare examples would be excluded from 9705 [1].
• Working the stone changes the heading. Natural amber stayed among crude minerals; sanded and buffed amber moved to worked carving material, with a duty rate [1].

The notice was a proposal dated March 22, 2021, with comments due May 21, 2021 [1]. The final CBP notice was not read for this edition. A commercial tariff rulings database lists one of the four rulings, NY N004200, as "REVOKED" and "Superseded by" HQ H311301, the ruling CBP proposed [4], which suggests the proposal was adopted at least for that ruling; that database is not a CBP source and gives no date or Customs Bulletin citation. Check CBP's rulings database (CROSS) or ask a broker for the final status before relying on either classification. The broader lesson stands either way: do not assume a mineral enters as a duty-free "specimen" because it is a natural mineral. Classification turns on what the material is, whether it is worked, and whether it really has collector interest.

Paperwork an importer meets

Sanctioned countries and source-country export laws are not listed here, because both change often and none of the sources cited gives a current summary for minerals. Ask your broker about sanctions before you buy, and ask your supplier for the export permit before you pay.

Country of origin marking

The marking rule is broad. Under 19 CFR 134.11, "Unless excepted by law, section 304, Tariff Act of 1930, as amended (19 U.S.C. 1304), requires that every article of foreign origin (or its container) imported into the United States shall be marked in a conspicuous place as legibly, indelibly, and permanently as the nature of the article (or container) will permit, in such manner as to indicate to an ultimate purchaser in the United States the English name of the country of origin of the article, at the time of importation into the Customs territory of the United States" [2]. The rule names the container as well as the article. Part 134 sets out its exceptions in Subpart D, sections 134.31 to 134.36 [3]; whether one fits a shipment of loose stones or specimens is for a broker or CBP to say. Whatever the answer, keep the country of origin on your own stock records and labels, because buyers ask and the invoice is your evidence.

Fossils, meteorites and artifacts from abroad

These carry the most risk in imported lots. Many countries treat fossils, meteorites or archaeological objects as state property or restrict their export, and material exported in breach of those rules can be seized. U.S. law adds its own limits on what may be sold once it is here. Before you import any of them:

1. Get the export permit or written statement from the exporting country's authority, through the supplier.
2. Keep the permit with the invoice and the piece.
3. Read the U.S. side: can you sell fossils?, meteorites on public land and arrowheads and other artifacts.

An importing checklist

1. Before ordering, ask the supplier for the stone's name, country of origin, any treatment and, for fossils and meteorites, the export permit.
2. Have the HTS classification checked for each kind of item, and the duty rate, including any country-specific duties.
3. Ask a broker about sanctions affecting the country or the supplier.
4. Require an itemized commercial invoice: item, quantity, weight, value, origin, treatment.
5. Keep every document (invoice, entry papers, broker's classification, permits) with your stock records; see what you have to write down.
6. Disclose treatments when you resell; see disclosure.

Choosing the supplier abroad

The paperwork is only as good as the supplier who fills it in. How to judge a supplier, what to ask about treatments and origin, and what a good invoice looks like are on who to buy from.
