Thailand

You're traveling with a GoPro Hero 12 and its dive housing, plus a DJI Osmo Action as a backup: total value around €700, well below the 80,000 THB allowance. Upon arrival in Bangkok (Suvarnabhumi) or Phuket, you can use the green channel without formalities: this compact equipment is clearly for personal use. Nevertheless, keep your invoices (paper or digital) and note down the serial numbers before departure. The risk is almost zero: Thai Customs isn't interested in tourists' action cams. The only precaution: avoid bringing multiple new, packaged items, which could suggest resale in Thailand and trigger import duties (up to 30% + 7% VAT). A used camera in its housing, mounted on a floating grip, poses no problem.

Your kit: Sony A6700, Ikelite housing, two Sea&Sea strobes, a macro lens. Approximate value €3,500, which is above the 80,000 THB (~$2,200 USD) allowance. In practice, Thai Customs is tolerant of clearly used recreational equipment, but the prudent approach is to go through the red channel and declare the equipment as temporary personal effects intended for re-export. Present a list with serial numbers, invoices, and your dive bookings (Koh Tao, Similan) proving recreational use. The officer may register the equipment for re-export. The risk if you go through the green channel and are inspected: possible taxation (0–30% duties + 7% VAT) or a prolonged discussion. Visibly used equipment, packed in a dive bag with a wetsuit and regulator, strongly argues in your favor.

Expert kit: Canon R5 II, Nauticam housing, fisheye dome, macro and wide-angle lenses, aluminum arms, two Retra strobes — value €14,000, far exceeding the allowance. Two options. Strictly personal use: mandatory red channel upon arrival, declaration as temporary personal effects with a detailed list (serial numbers, invoices), commitment to re-export; Thai Customs may request a guarantee but generally remains flexible for recreational divers. Professional use (commercial shooting, production): ATA Carnet highly recommended — accepted by Thailand, must be stamped at the red channel upon entry AND exit, otherwise you risk losing the bond. Alternative: bond via an authorized Thai broker. Risks: non-declaration = taxation (up to 30% + 7% VAT) or even seizure of equipment; forgetting the exit stamp on the carnet = claim on the bond.

Do I need to declare my underwater photography equipment when arriving in Thailand?

If your total equipment value is under 80,000 THB (~$2,200 USD), it's covered by the personal effects allowance: the green channel is an option. Above that, go through the red channel and declare it as temporary personal effects with invoices and serial numbers. Thai Customs is generally understanding with tourist divers, but a proactive declaration protects you from any surprise taxation (0–30% duties + 7% VAT).

Is an ATA Carnet useful for a dive photographer in Thailand?

Yes, if your use is professional (video production, commercial shooting) or if your kit significantly exceeds the allowance. Thailand accepts the ATA Carnet for audiovisual equipment. Be aware: it's mandatory to present it at the red channel upon entry and exit to get it stamped, and re-export must occur within one year. For purely recreational use, a simple temporary declaration is usually sufficient.

What are the risks if I go through the green channel with expensive gear without declaring it?

In the event of a random check, Thai Customs may demand import duties (up to 30% depending on the category) plus 7% VAT on the equipment's value, or even seize the equipment in case of a dispute. Visibly used equipment accompanied by dive gear argues for personal use, but above 80,000 THB, the red channel is strongly recommended to avoid any risk.
