In short: Guatemala’s arms law is precise about knives and silent about sprays. Decreto 15-2009 defines bladed weapons in Art. 13 down to the centimetre — a pocket-knife blade up to 10 cm is “personal or work use”, while an automatic (switchblade) knife of any length sits in the military-exclusive class that Art. 122 punishes with three to five years’ non-commutable prison. The same law never mentions pepper spray, OC, mace or an electroshock device anywhere. And for the suitcase question, the aviation rule answers first: IATA forbids disabling sprays and Tasers in checked baggage, carry-on baggage and on the person. This is general information, not legal advice.

Most articles about carrying self-defense items abroad end with a confident verdict. This one will not, because the governing instrument does not supply one — and knowing exactly where the law goes quiet is more useful than a guess dressed up as an answer.

Guatemala’s Ley de Armas y Municiones (Decreto 15-2009 del Congreso de la República) does something unusual: Art. 4 lists eleven classes of weapon and the articles that follow define each class one at a time. That structure makes the silences legible. If a category is not in Art. 4 and not defined in Arts. 5-20, the Law has not been written to reach it.

The three answers, side by side

ItemWhat the Guatemalan instrument saysWho decides your flightResult at the airport
Pocket knife, blade ≤ 10 cmArt. 13(a): “personal or work use” classTSA (US departure)Checked bags only; no carry-on
Non-automatic knife, blade > 10 cmArt. 13 closing paragraph: “may be used in extra-urban areas”TSAChecked bags only

Bear sprayNot namedTSANo in carry-on and No in checked
Tear gas (CS/CN) above 2% by massArt. 15 defines chemical weapons by warfare designTSANo in carry-on and No in checked

Two different legal systems are doing the work in that table, and they belong to different bodies. DIGECAM (Dirección General de Control de Armas y Municiones, under the Ministerio de la Defensa Nacional) administers Guatemala’s arms law. TSA screens US departure checkpoints. FAA writes the US hazardous-materials rule for passenger baggage. IATA/ICAO set the international standard airlines apply. None of them speaks for the others.

Knives: the law names the measurement

Art. 13 of Decreto 15-2009 is the whole answer, and it is short enough to read in full. It splits armas blancas into three:

(a) Personal or work use. “los cuchillos de exploración o supervivencia, instrumentos de labranza o de cualquier oficio, arte o profesión, que tengan aplicación conocida; las navajas de bolsillo cuya hoja no exceda de diez centímetros de longitud.” The article then carves an explicit hole in its own scope: “No están comprendidos en las disposiciones de esta Ley, los cuchillos, herramientas u otros instrumentos cortantes que tengan aplicación artesanal, agrícola, industrial u otra conocida.”

(b) Sporting. “las ballestas, arcos, flechas, florete, sable y espada.”

(c) War use or exclusive to the State security forces. “las bayonetas, dagas, puñales, verduguillos, navajas automáticas con hojas de cualquier longitud y cualquier objeto diseñado o transformado para ser usado como arma.”

And then the closing line, which is the part almost nobody quotes: “Las navajas con hojas que exceden de diez centímetros y que no sean automáticas, se podrán usar en áreas extraurbanas.

Three things follow directly from that text. First, the mechanism matters more than the blade length — an automatic knife is in class (c) “con hojas de cualquier longitud”, so a small switchblade is treated more severely than a large fixed-blade knife. Second, Art. 122 attaches the penalty only to class (c): “prisión de tres (3) a cinco (5) años inconmutables y comiso de las armas.” Third, Art. 144 closes the door on regularising a class (c) blade — “En la DIGECAM solamente se podrán registrar armas de fuego; consecuentemente las armas blancas bélicas o de uso exclusivo del Ejército de Guatemala a que se refiere la literal c) del artículo 13 de esta Ley, al no ser registrables, deberán quedar en depósito en la DIGECAM.” There is no licence to apply for.

What the Law does not define is “áreas extraurbanas”. No definition appears in the Law or in its regulation, Acuerdo Gubernativo 85-2011, and no published DIGECAM guidance defining it was located.

Pepper spray: the silence, stated precisely

Here is what was actually checked, so you can judge the claim rather than take it.

The Organismo Judicial’s consolidated publication of the Ley de Armas y Municiones together with its Reglamento (Acuerdo Gubernativo 85-2011) — roughly 294,000 characters of text — was searched for pimienta, aerosol, irritante, capsaicina, lacrimógeno, electrochoque and paralizante. Every one of those searches returned zero matches.

The class that comes closest by name is Art. 15 — reformed by Art. 12 of Decreto 22-2012 — and it is defined by purpose: “Se consideran armas químicas las sustancias químicas tóxicas, orgánicas o inorgánicas, o sus precursores, diseñados para fines bélicos, que afecten el funcionamiento normal del organismo de personas, animales y plantas, al entrar en contacto con éstos así como sus municiones, dispositivos y equipos; salvo cuando se destinen a fines no prohibidos por la ley y los convenios o tratados internacionales aceptados y ratificados por Guatemala, siempre que los tipos y cantidades de que se trate sean compatibles con esos fines.” The definition is anchored to warfare design, not to irritant effect, and the 2012 reform kept that anchor in place.

One clause deserves a flag rather than a conclusion. Art. 13(c) — the bladed-weapons article — ends with the open phrase “y cualquier objeto diseñado o transformado para ser usado como arma”. It sits inside the article headed Armas blancas. Whether that catch-all would be read to reach a pressurised irritant canister is not something any published instrument or DIGECAM guidance addresses, and this page does not resolve it.

So the accurate statement is the narrow one: Decreto 15-2009 governs firearms, compressed-gas weapons, bladed weapons, explosives and weapons of war, and it does not mention pepper spray; no instrument was found either authorising or prohibiting it. That is not the same sentence as “so it is legal to bring”, and the difference matters if you are the person carrying the canister.

Electroshock devices: silent in the law, forbidden in the air

The same searches found no term for a taser, stun gun or electroshock device anywhere in the Law or its regulation.

It is worth being clear about the nearest neighbour, because it is easy to misread. Art. 12 defines “armas de acción por gases comprimidos” as pistols and rifles that release previously compressed gas to propel a projectile, using ammunition up to 5.5 mm. Art. 68 then grants a real, explicit permission for exactly that category: “Es permitida la tenencia sin registro y el traslado sin licencia, de armas de acción por gases comprimidos… hasta de cinco punto cinco (5.5) milímetros o cero punto veintidós (0.22) de pulgada de diámetro.” That is an air-gun rule. It is written about a projectile weapon and cannot be stretched across to a conducted-electrical device.

The air-travel side, by contrast, is explicit. IATA’s Dangerous Goods Regulations Table 2.3.A lists: “Electro shock weapons (e.g. Tasers) containing dangerous goods such as explosives, compressed gases, lithium batteries, etc. are forbidden in carry-on baggage or checked baggage or on the person.” The table marks the row FORBIDDEN across every column.

The aviation rule settles the suitcase before Guatemalan law is reached

This is the part that catches out American travellers, because the US domestic rule and the international rule genuinely differ.

BodyInstrumentSelf-defense spray
TSA (US checkpoint)“What Can I Bring?” item entry, last updated 29 Mar 2023Carry-on No; checked Yes — one 4 fl oz (118 ml) canister with a safety mechanism; >2% CS/CN prohibited
FAA (US hazmat)PackSafe, citing 49 CFR 175.10(a)(9), last updated 13 Apr 2026One spray ≤118 ml, checked baggage only, positive means to prevent accidental discharge
IATA / ICAO (international)Dangerous Goods Regulations, Table 2.3.AFORBIDDEN — “forbidden on the person, in checked and carry-on baggage”

The FAA does not leave the conflict for the traveller to spot. Its own PackSafe page carries this note directly beneath the US allowance: “Important note: International aviation regulations (ICAO/IATA) prohibit self-defense sprays in both carry-on and checked baggage.” TSA adds its own caveat on the same item — “We recommend checking with your airline as some may not allow this item in checked bags.”

A flight from the United States to Guatemala is an international flight. The US checked-baggage exception is the outlier, not the rule.

Edge cases worth knowing

  • Multi-tools. TSA’s entry is split: multi-tools with knives of any length are prohibited in carry-on; multi-tools with scissors under 4 inches may go in carry-on. Sharp objects in checked bags “should be sheathed or securely wrapped”.
  • Bear spray is not pepper spray, procedurally. TSA marks it No in both carry-on and checked. The FAA explains why: most bear sprays exceed 118 ml, so the checked-baggage exception the smaller canisters rely on does not apply.
  • Body armour is a separate Guatemalan regime, not a silence. Art. 109 of Decreto 15-2009 requires DIGECAM authorisation for anyone manufacturing or selling bulletproof vests, with a criminal penalty of two to four years for illicit commercialisation. The article regulates the trade, not a traveller’s own vest.
  • The catch-all in Art. 82. The Law’s general prohibitions on private parties include silencers, automatic-conversion mechanisms, and “artificios para disparar el arma de forma oculta, como maletines, estuches, lapiceros, libros y similares” — concealed-firing devices disguised as briefcases, cases, pens or books.
  • Customs is a third body again. SAT’s published traveller-baggage guidance routes weapons and ammunition through permit control rather than the ordinary baggage exemption; our page on prohibited and restricted imports covers that side, and the customs guide for travellers covers the ordinary allowances.

For the firearms question specifically — tourists, US carry permits, and what DIGECAM actually publishes — see guns in Guatemala for Americans. The full set of DIGECAM procedures lives in our MINDEF trámites hub, and if your underlying question is really about risk rather than equipment, start with is Guatemala safe for families.

Not published / not found, as of 2026-08-11: no definition of “áreas extraurbanas” appears in Decreto 15-2009 or Acuerdo Gubernativo 85-2011; no DIGECAM guidance was found applying Art. 13(c)’s catch-all to a chemical irritant; no DGAC (Dirección General de Aeronáutica Civil) passenger prohibited-items list was located on its public portal, which serves a JavaScript-only shell.
