How to stop worrying about import tax on your own equipment – especially if you travel to Mexico more than once a year or carry high-value gear.

 

The short version

 

Dive & Photography Gear in Mexico: The ATA Carnet Guide

 

This doesn’t happen on every trip or to every diver – reports describe it as sporadic, with no clear pattern to which travelers or which equipment get flagged. That unpredictability is a big part of what makes it so frustrating: there’s no way to know in advance whether your gear will draw attention. What actually triggers it isn’t a judgment about whether you’re going to sell the equipment – it’s whether an agent decides the gear looks professional-grade rather than ordinary personal belongings. A well-loved dive computer and a hobbyist’s camera housing can get swept into that judgment just as easily as something a working photographer owns. It isn’t limited to dive gear, either – drone operators report similar scrutiny, and so do travelers carrying more electronics than usual (an extra laptop, a tablet, a second camera body). This guide focuses on dive and underwater-photography equipment specifically, since that’s where it hits most often, but the approach below applies just as well to a drone, a laptop, or any other personal electronics an agent might flag.

 

Even where there’s technically a process to reclaim tax paid at entry by presenting your gear and receipt again on the way out, divers who’ve tried it report not actually getting their money back – so it’s worth treating that option as unreliable in practice, whether or not it exists on paper.

 

Some travelers have pointed to a social media post attributed to a Mexican customs official referencing internal meetings on this issue. That’s the extent of what’s circulating – no agency has published a policy change, and no pause on enforcement has been confirmed by any official source. Worth keeping an eye on, not worth planning your trip around.

 

What’s actually exempt, and why coverage is still inconsistent

 

Mexico’s customs rules – set by ANAM (Agencia Nacional de Aduanas de México, Mexico’s customs agency) – exempt a specific list of personal baggage items, regardless of value, as long as the quantities and use match an ordinary trip. As of this writing, that list includes:

 

  • Clothing, footwear, and toiletries appropriate to the length of
    the trip
  • Two still or video cameras, plus photographic
    material/accessories for them
  • Three cell phones or other wireless devices
  • One GPS unit and one electronic organizer/agenda
  • Two tablets and two laptops (or similar portable computers), with
    accessories, per ANAM’s general baggage page – but see the note below,
    because this figure conflicts with other official guidance and with
    what’s actually being enforced.
  • One portable printer/copier, one disc burner, and one portable
    projector, with accessories
  • Two personal sports equipment sets, four fishing rods, three
    gliders/boards with or without sail and their accessories, and trophies
    or awards – as long as a passenger can reasonably carry them
  • A range of other personal-use items in specific quantities – for
    example, a blood pressure monitor and glucose meter with supplies, and
    personal medications. For the complete list and current quantity limits,
    see the ANAM source below.

A full scuba kit plausibly falls under “two personal sports equipment sets,” and underwater photography gear could reasonably extend from the “cameras plus photographic material” exemption too – so on paper, most recreational divers’ equipment may already qualify as exempt. The real problem is that these categories are broad and undefined: nothing in the published rule spells out exactly what counts as one “sports equipment set,” or where “photographic material” stops and a separate underwater housing or strobe begins. That leaves it up to whichever agent is working the line that day, which is exactly why enforcement is so inconsistent – some equipment gets waved through as obviously covered, and functionally similar equipment gets flagged as falling outside it, without a clear rule either way to point to in the moment.

 

Important: don’t rely on “two laptops, two tablets” in practice

 

ANAM’s general baggage page says two of each, but the Mexican Consulate General’s own guidance to travelers describes a stricter rule: only ONE laptop, tablet, or similar portable computing device duty-free per person – treating laptops and tablets as the same category, not separate allowances. Real travelers have been fined for this at major airports (Cancun, Mexico City, and Toluca have all been reported), not just at land crossings – one widely reported case involved a traveler charged roughly $190 for bringing both a laptop and an iPad. Two official Mexican sources contradicting each other is obviously confusing, but the practical reality for anyone planning a trip is clear: budget for ONE laptop-or-tablet-type device as duty-free, and treat a second one as genuinely at risk of a 19% duty assessment, regardless of what the general baggage page states.

 

One more note: the duty-free threshold is slightly lower if you’re driving into Mexico rather than flying, so budget a little tighter if you’re crossing by land.

 

One more thing worth understanding precisely: you may see $3,000 (or $4,000 for computer equipment) mentioned as a cap. That figure only applies to items that fall OUTSIDE the personal baggage list above – it isn’t a limit on how much personal gear you’re allowed to own overall, and it never applies to anything already covered by the list. For items outside the list, $3,000/$4,000 is the ceiling on Mexico’s simplified passenger process, where you can self-declare and pay a 19% tax directly at the counter without needing a customs broker. Below that figure, an agent can assess and collect the tax on the spot. Above it, the law technically requires a formal, broker-handled import – which almost never happens at an airport passenger line in practice, but means there’s no clean, legal way to resolve a dispute over expensive gear at the counter at all.

 

A carnet sidesteps this entire question – the exemption list, the $500 threshold, and the $3,000/$4,000 cap – completely. None of it applies to equipment that’s already on a carnet, at any value. The carnet doesn’t ask whether your gear happens to be on Mexico’s personal-baggage list; it’s independent proof, agreed to in advance, that everything on it is temporary and personal, so the whole exempt-list/threshold question never comes up.

 

What an ATA Carnet is, and how it actually protects you

 

When Mexican customs taxes equipment that an agent decides doesn’t fit those exemption categories, they’re applying import duty – the same charge that would apply to commercial merchandise. The trigger isn’t a judgment about whether you plan to sell the item; it’s simply that anything an agent doesn’t recognize as covered gets defaulted into that same commercial-goods bucket. Once that tax is charged, your only official path to get it back is to keep your gear and your receipt for the tax paid, and present both again on your way out of the country – and as noted above, that path rarely seems to work in practice.

 

An ATA Carnet solves this from the other direction: instead of paying the tax and trying to reclaim it, the carnet is proof, before you ever reach customs, that everything on it is temporary personal property that will leave the country again. It’s a pre-approved, internationally recognized customs document – sometimes called a “merchandise passport” – backed by a financial guarantee you post when you apply. Because that guarantee already covers the duty if you somehow don’t bring the goods back out, customs has no reason to charge you the import tax in the first place: they stamp the carnet instead of assessing you.

 

A single carnet is valid for one year from the date it’s issued and can be used again and again during that year, not just for one trip – in Mexico or in any other country that accepts carnets. What actually limits how many trips you can make on one booklet is the number of voucher sets inside it, not the carnet itself: the standard processing fee includes 4 sets of vouchers. Exactly how many Mexico round trips 4 sets covers depends on how your provider structures the U.S. and Mexico paperwork together, so ask them this directly when you apply – get the exact number in writing before you rely on it. If you expect to travel more than that within the year, you can buy additional sets, either at the time you first apply or later if you start running low: expect roughly $20-25 per additional set, with an $80 minimum charge even if you only need one or two more. Adding sets doesn’t require a new carnet or a new application – your existing provider issues and mails you the additional pages for the same booklet.

 

Carnets are accepted in more than 80 countries and territories beyond Mexico. If you also travel elsewhere with the same gear, check the current country list before you go, since rules and acceptance vary by destination.

 

 

What the physical document looks like

Diagram: structure of a real ATA Carnet booklet (illustrative, not an actual issued carnet)

 

  • The cover is printed on distinctive green card stock and states
    the issuing association, the holder’s name, validity dates, and
    countries covered – recognized by customs officers worldwide.
  • Inside are perforated voucher/counterfoil pages, one pair per
    border crossing. The officer detaches and stamps a voucher on exit or
    entry; a matching counterfoil stays in the booklet as the paper
    trail.
  • The General List is printed on the inside back cover (or
    attached) and itemizes every piece of equipment covered.
  • You never print or design this yourself. Once your application is
    approved, the issuing association mails you the actual booklet.

 

How to get one – the full process

This whole process breaks into three phases: things you do ONCE to set up the carnet, things you REPEAT every single time you travel, and one thing you do ONCE at the very end.

PHASE 1: One-time setup (before your first trip)

Step 1 – Inventory your equipment

List every item you’ll carry: make, model, serial number (or another identifying mark – see the tips at the end of this document), and a fair current value. Photograph each item. Add up the total value – this determines your processing fee and security deposit.

Step 2 – Decide: cash or bond

Every carnet requires security equal to 40% of your total equipment value, to guarantee that duty will be paid if you don’t bring the goods back out. This decision matters for the rest of the carnet’s life, so understand both options fully before choosing:

  • BOND (what most individual travelers use): a surety company promises Mexican customs, on your behalf, that duty will be paid if something goes wrong. You pay them a one-time, non-refundable premium for that promise – typically well under $100 on a $5,000 equipment list. This premium is gone the moment you pay it, the same as an insurance payment – you never get it back, whether your trip goes perfectly or not. The real risk with a bond isn’t losing that premium – it’s this: if a crossing doesn’t get stamped and there’s no proof your gear left Mexico, the surety company pays Mexican customs the duty owed, and then bills YOU to reimburse them, because you personally agreed to that when you signed up for the bond. That can mean owing real money – potentially the full guaranteed amount – that you never had sitting anywhere to begin with. This is why hitting every stamp at every crossing (covered in Phase 2 below) matters so much when you’ve chosen a bond.
  • CASH: you pay the full 40% directly to the provider as a deposit instead. This money IS refundable – you get it back once you’re done using the carnet and the provider verifies everything was properly stamped. The tradeoff is that it’s your own money tied up for as long as you hold the carnet, and refunds take 4-6 weeks after you return the completed carnet at the very end.

For most divers and photographers, the bond is still the practical choice – small one-time cost, nothing tied up – as long as you’re disciplined about getting every crossing stamped every time.

Step 3 – Apply through an authorized provider

Carnets are issued only by the U.S. Council for International Business (USCIB), through two appointed service providers – Roanoke Trade and boomerang carnets. Either can process everything in one application: the carnet itself, your bond or cash deposit, payment of the processing fee, and registering your first trip with Mexican authorities.

  • Contact Roanoke Trade or boomerang carnets directly (links below) and tell them you need a carnet for personal dive/photography equipment traveling to Mexico.
  • They’ll ask for your completed General List (values, descriptions) and basic applicant information – use the worksheet later in this document to have it ready.
  • Tell them upfront whether you want the bond or cash option – now that you understand what each actually means.
  • Ask them directly how many Mexico round trips your included 4 voucher sets will cover, and what additional sets cost if you expect to travel more than that in the next 12 months – get this in writing.
  • Pay the processing fee: $255 for equipment lists under $10,000, $300 for $10,000-$49,999, and higher above that – plus your bond premium or cash deposit, and any additional voucher sets.
  • CRITICAL – Mexico requires your FIRST trip to be registered with CANACO (the Mexican carnet authority) at least 7 days before you arrive, and Mexican Customs can take 2-3 more days to approve it. Your provider handles this registration as part of your application, but only if you give them your travel dates early enough for that window to close before you fly. Processing plus this registration means you should apply at least 3-4 weeks before your first trip, not just a few days.

Step 4 – Verify the carnet when it arrives

Check every item and value on the printed General List against your actual equipment before you travel. Mistakes are much easier to fix now than at an airport counter.

PHASE 2: Every single time you travel (repeat this entire phase for trip 2, trip 3, trip 4…)

This is the part that’s easy to miss: getting the carnet in Phase 1 does NOT mean you’re set for every future trip. Everything below happens again, in full, before and after every individual visit to Mexico on this carnet – your second trip requires the same registration and reporting as your first.

2a – Register THIS specific trip with CANACO, at least 7 days out

Contact your provider again (or use CANACO’s registration portal yourself) and give them the dates for this specific trip. This has to happen at least 7 days before you arrive, with 2-3 more days for Mexican Customs to approve it – so plan on contacting them at least 10 days before you fly, every time. This step does not carry over from a previous trip; it must be redone for each one.

2b – Leaving the United States: get it stamped BEFORE you check your bags

Present the carnet and the physical goods to U.S. Customs and Border Protection for an export stamp before your equipment disappears into checked baggage.

  • Get it stamped at the last place you and your bag are physically together before the equipment leaves your hands – for nearly everyone, that’s your ORIGINATING U.S. airport, before you check your bag in. The one exception: if your itinerary requires you to physically claim and recheck your bag partway through your trip, present the carnet at that point instead.
  • Find the U.S. Customs office at whichever airport applies to you – often a separate “cargo” or “client services” office, not the regular passport-check line. Ask ahead of time.
  • Arrive with extra time – budget at least an hour beyond your normal check-in buffer.
  • Show the officer your carnet AND the actual equipment so they can match items to the General List, then get the export voucher stamped.

2c – Arriving in Mexico

  • Present the carnet along with your equipment at Mexican customs. Mention you’re carrying an ATA Carnet if it isn’t obvious what the green booklet is.
  • The customs officer stamps an import voucher; keep the carnet with you for the rest of the trip.

2d – Leaving Mexico

  • Present the carnet and equipment to Mexican customs again for a re-export stamp before you depart. Don’t skip this even if no one asks – it’s what proves the gear is leaving the country.

2e – Returning to the United States

  • This does NOT happen through the “nothing to declare” exit or an automated kiosk. You must find a CBP officer in the arrivals/inspection area and have them stamp the re-importation voucher, even if you have nothing to declare in the ordinary sense.
  • Present the carnet and equipment together. It’s your responsibility as the carnet holder to track down an officer if one isn’t immediately visible.

2f – Report back to CANACO within 1 week of leaving Mexico

Scan your stamped carnet pages (both the Mexico entry and exit stamps) and email them to CANACO or your provider within one week of leaving Mexico. This closes the loop on this specific visit’s registration from Step 2a. Skipping this reporting step is exactly the kind of gap that can leave a visit looking unresolved later – which matters most if you’re on a bond, for the reason explained in Step 2 above.

Every one of those six steps (2a through 2f) happens again, from scratch, for your next trip on the same carnet – even though it’s still the same booklet, still the same bond or deposit, and you don’t reapply or repay anything to get the carnet itself again.

PHASE 3: Closing out the carnet (once, at the very end)

Once the carnet expires (12 months from issuance) or you’re simply done using it, mail the completed booklet back to your provider. What happens next depends on what you chose in Step 2:

  • If you paid CASH: your provider verifies every crossing across every trip was properly stamped, then refunds your deposit – typically 4-6 weeks after they receive the carnet back.
  • If you used a BOND: there is no refund, because a bond premium was never a refundable deposit in the first place. Sending the carnet back closes out the guarantee with the surety company. As long as every crossing on every trip was properly stamped, nothing further happens – the bond simply expires unused. If something is missing or unresolved, that’s when the risk described in Step 2 becomes real.

Tips for items with no obvious serial number

 

  • Use whatever mark exists – a model number, batch/lot code, or
    printed identifier counts, even if it isn’t a formal serial
    number.
  • Create your own mark if nothing exists: an engraving, a UV-pen
    mark, or a small durable tag with a unique code, recorded on the General
    List.
  • Describe distinguishing features – color, size, brand, wear
    patterns – when there’s genuinely no mark to use.
  • Photograph everything. A photo tied to the item number on your
    list resolves ambiguity even when the written description is
    thin.
