CITES: The Materials That Can Stop You Selling or Moving What You Own

An inherited cabinet with ivory inlay. A vintage watch on its original exotic-leather strap. A Victorian brooch set with coral. A guitar with a rosewood fingerboard. A handbag in a skin whose name nobody thought about at the time.

Every one of those may be perfectly lawful to own and unlawful to sell, and in several cases unlawful to carry across a border without paperwork obtained in advance.

This is among the most consequential things a collector can be unaware of, and it is almost never mentioned in guides to buying beautiful objects.

What the rules actually regulate

CITES — the Convention on International Trade in Endangered Species of Wild Fauna and Flora — is an international agreement with a very large number of parties, implemented through each one's own domestic law. Its subject is trade, and its unit is the specimen, which includes worked items and parts, not just live animals and plants.

That is the point people miss. A piano is not an elephant. A piano with ivory keys contains a specimen, and the rules follow the material rather than the object it has become.

In the UK the implementing instrument is the Control of Trade in Endangered Species Regulations 2018, which operates alongside the retained EU regulation it identifies as the Principal Regulation — Council Regulation (EC) No 338/97 on the protection of species of wild fauna and flora by regulating trade therein.

The conduct that is an offence is broader than "selling"

This is where the surprise lives. Schedule 1 to those Regulations sets out the conduct that is an offence in relation to a specimen, in contravention of Article 8 of the Principal Regulation. The list is:

• purchasing
• offering to purchase
• acquiring for commercial purposes
• using for commercial gain
• displaying to the public for commercial purposes
• selling
• keeping for sale
• offering for sale
• transporting for sale

Read the emphasised entries again. Offering to purchase is on the list. So is displaying to the public for commercial purposes — which reaches a dealer's window, a stand at a fair, and arguably a listing photograph.

The penalty is not nominal either: on summary conviction, imprisonment for up to six months or a fine or both; on conviction on indictment, imprisonment for a maximum term of five years or a fine or both.

None of that is aimed at collectors. It is aimed at a trade that has driven species toward extinction. But the offences are drafted by conduct, and a private seller listing an inherited object commits the same conduct as a trafficker, without any of the intent.

Owning is not the problem

It is worth stating plainly, because the rules are often reported as though possession were criminalised.

In general, holding an item you already own is not the regulated act. The regulated acts are commercial ones — buying, selling, offering, displaying for commercial purposes — and movement across borders, which requires permits or certificates in its own right.

So an inherited object can sit in a house indefinitely without engaging any of this. The engagement happens at exactly the two moments a collector cares about: when it is sold, and when it is moved.

Certificates, and why they must come first

Where a specimen is in the most restricted category, a commercial transaction generally requires a certificate issued in advance by the relevant national authority, and cross-border movement requires import, export or re-export permits.

Two features of that process matter more than any detail of it.

It takes time. Applications are assessed, not stamped, and the timescale is measured in weeks rather than days. A buyer who wants to take an object home after a fair, or a seller who has agreed a date, will not be accommodated by the system's speed.

Documentation is about the specimen's history. Age, origin and how the material was acquired are what applications turn on. An object with paperwork establishing that history is a different proposition, legally and commercially, from an identical object without it — which is another reason the provenance file matters, and why jewellery authentication is worth doing properly before you need it.

Practical steps

• Identify the materials before you buy. Ask, in writing, what everything is made of. "Bone", "horn" and "faux" are answers that should be evidenced rather than accepted.
• Ask the seller for CITES documentation at the point of purchase. It is far easier to obtain from a dealer at the moment of sale than from your own records ten years later.
• Do not travel with a doubtful item. Border officials are trained to spot the common materials and are not obliged to accept your account of an object's age. A confiscation is not usually reversible.
• Check before you consign to an auction. Auction houses have specialists for exactly this and will raise it — but discovering the problem at consignment means a wasted sale cycle rather than a planned one.
• Do not assume age solves it. Antique exemptions exist in some regimes and are narrower and more conditional than collectors expect, and for certain materials there are separate national bans that are stricter than the international convention.
• Get advice for anything significant. This is a specialist area with real criminal exposure, and a single professional opinion is cheap next to the alternative.

Why this is getting stricter, not looser

The direction of travel over the past decade has been consistently toward tighter national rules layered on top of the international convention — most visibly for ivory, where several countries have introduced near-total domestic sales bans with narrow exemptions, and where a decades-old collection can become legally unsaleable without any change in the object itself.

For anyone treating objects as a store of value, that is the real lesson. A material restriction does not reduce an object's price. It removes the market, which is a more complete loss than any price movement, and it is a risk you cannot hedge after the fact. Our piece on art as an investment makes the adjacent point about liquidity generally.

The Regulations quoted are the UK's, read on 19 August 2026; CITES is implemented separately in every party state and several impose stricter national rules. This is general information, not legal advice — take specialist advice on any specific object.
