Immediate rule: Small personal-care spray items are best transported in cabin under the 3‑1‑1 rule – each container ≤100 ml (3.4 oz), all containers in a single transparent resealable bag, one bag per passenger. Larger pressurised spray receptacles are subject to dangerous‑goods passenger exceptions and must meet IATA DGR packaging and quantity limits before being stowed in the aircraft hold.
IATA passenger exception for UN1950 (pressurised sprays) normally limits each individual receptacle to a maximum of 0.5 kg (500 g) net and a total of 2 kg net per person; damaged, corroded or leaking units are forbidden. Flammable propellant formulations (e.g., hydrocarbons, butane/propane blends) are more tightly controlled by many carriers and national regulators – in several jurisdictions such items are restricted or prohibited from hold carriage.
Operational recommendations: keep valves fully protected with original caps, place each receptacle in a sealed plastic bag to contain leaks, pad between soft items to reduce impact, and avoid overfilling checked bags to limit pressure on valves. Metered‑dose inhalers and medically prescribed pressurised devices should travel in the cabin with documentation and remain accessible during flight; check specific airline medical policies.
Before departure verify three sources: the operating carrier’s hazardous‑goods rules, the departure/arrival civil aviation authority (for example TSA, EASA), and the IATA DGR reference for UN1950. If quantities exceed passenger exceptions or if commercial shipment is required, arrange a licensed dangerous‑goods carrier with proper documentation; failure to comply may lead to confiscation, fines or flight delays.
Permitted and prohibited spray items for hold baggage
Deodorant sprays and hairsprays intended for personal hygiene are generally permitted in the aircraft hold if each pressurised container is no larger than 500 mL (500 g) and the aggregate net quantity of all pressurised personal-care sprays does not exceed 2 kg (70 oz) per passenger; containers must remain in original packaging with caps fitted and protected against accidental discharge.
Allowed personal-care sprays (deodorant, hairspray)
Deodorant: stick and roll-on formats present no special restrictions beyond normal toiletries. Spray deodorants: follow the 500 mL/500 g per-item limit and the 2 kg total-per-passenger limit. Keep labels intact; damaged or leaking items are prohibited.
Hairspray: treated the same as other cosmetic sprays. Because most formulations include flammable propellants, secure lids, place in a sealed plastic bag inside the hold bag, and declare at check-in if airline policy requires disclosure of pressurised toiletries.
Restricted or prohibited sprays (paint, insecticide)
Spray paint: generally not permitted in passenger baggage because of high flammability and pressure. Transport of spray-paint products is normally restricted to freight services that accept dangerous goods; do not place spray-paint containers in hold baggage.
Insecticide sprays: commonly prohibited for passenger transport due to toxic or poisonous ingredients and flammable propellants. Small personal repellents in non-pressurised formats (wipes, lotions) are safer alternatives. If in doubt, use cargo shipment or purchase at destination.
Operational advice: keep pressurised personal-care items in original, undamaged containers with caps, limit aggregate quantity to 2 kg per passenger, declare any hazardous-item doubts to the airline or check-in agent before handing over hold baggage, and consult the carrier’s dangerous-goods guidance for route- or carrier-specific prohibitions.
Volume and pressure limits for pressurised spray products in the aircraft hold under IATA and airline rules
Recommendation: each pressurised spray product should be no more than 500 mL (or 500 g net mass) and the total net quantity per passenger stowed in the aircraft hold should not exceed 2 kg; flammable or otherwise classified hazardous sprays must not be transported in passenger baggage without dangerous-goods handling.
IATA specifics
Most pressurised spray items fall under UN1950 (pressurised receptacles). IATA Dangerous Goods Regulations permit retail-type personal care and toiletry sprays under the Limited Quantity provisions: individual receptacles ≤0.5 kg (500 g or ~500 mL) net mass, aggregate net quantity per passenger ≤2 kg. Receptacles must be designed for transport (intact valve, protective cap or actuator) and not exhibit leakage or damage. Commercial quantities, large refill containers or items containing flammable propellants outside the LQ limits require full dangerous-goods documentation and are transported only as cargo with special packaging and marking.
Airline variations and practical steps
Individual carriers may impose stricter limits or outright bans (commonly on flammable sprays such as spray paints, solvent-based products or insecticides). Before travel, consult the carrier’s hazardous-goods page and the IATA DGR for the latest requirements. Practical steps: keep items in original retail packaging with caps fitted, isolate from other belongings in a sealed plastic bag, verify no visible damage or pressure loss, and declare any quantity that approaches the LQ aggregate during check-in so ground staff can advise or remove items if required.
How to avoid leakage, rupture or accidental discharge of pressurized spray containers in hold baggage
Store each pressurized spray product upright inside a heavy-duty, resealable polyethylene bag (minimum 4 mil / 0.1 mm thickness), with the actuator taped and the factory cap secured; place that bag inside a second sealed bag with absorbent padding.
Packing technique – stepwise
1) Protect the actuator: press the nozzle fully, apply a strip of strong tape (gaffer, duct or PVC) across the actuator and around the top to prevent accidental depression; leave the factory cap on and add a snug plastic wrap layer beneath the cap when possible.
2) Primary containment: place the protected item inside a heavy-duty zip-top bag with an absorbent layer (paper towel, sanitary pad, or microfiber cloth) to capture any leakage and reduce internal movement.
3) Secondary containment: add a second sealed bag outside the first; in case of failure this provides an additional barrier and keeps surrounding garments dry.
4) Cushioning and placement inside the suitcase: nest the double-bagged unit in the suitcase core, surrounded by soft clothing on all sides; avoid placement next to sharp objects, hard edges, or near batteries and electronics.
5) Hard-sided case preference: use a rigid shell suitcase when transporting multiple pressurized sprays; impact resistance lowers rupture risk during rough handling.
Handling, temperature and prevention tips
Avoid exposure to temperatures above 120°F (49°C) and to strong impact or crushing forces; prolonged heat increases internal pressure and raises rupture likelihood. Do not puncture or depressurize products prior to travel. For products that must be close at hand, carry them as cabin items in a padded personal bag such as best messenger bag to carry in new york, where pressure and temperature changes are less extreme and accidental actuation is easier to detect.
Obtain written confirmation from the airline and relevant security authority before placing pressurised spray products into the aircraft hold
Immediate action: contact the operating carrier’s Dangerous Goods / Cargo desk and the departure airport security office at least 72 hours before travel. Provide exact product name, manufacturer, full quantity per item and total quantity, packaging type, and the intended placement in the hold. Request a written acceptance or refusal (email or PDF).
Step-by-step verification checklist
1) Airline policy: open the carrier website and find “dangerous goods” or “restricted items” pages; if unclear, call the airline’s DG office. Useful search phrases: “[airline name] dangerous goods policy”, “[airline name] hazardous materials acceptance hold baggage”. Note airline-specific limits and any written permit procedures.
2) International/regional rules: consult IATA Dangerous Goods Regulations (DGR) summaries and the civil aviation authority for origin, transit and destination states. Confirm whether transit airports impose additional prohibitions or require special documentation.
3) National security body (US): refer to TSA hazardous materials guidance (tsa.gov – search “hazardous materials” or “transporting dangerous goods”) and DOT/HMR references for classification. For non-US flights, check the equivalent regulator (CAA, EASA, CASA, etc.).
4) Product classification: locate the Safety Data Sheet (SDS) and the product label. Identify UN number (commonly UN1950 for non-refillable spray items), classification (flammable gas, toxic, insecticide), net quantity per item and total gross quantity. Provide these details when querying authorities.
What to request and keep as proof
Request from airline/security: written acceptance for carriage in the hold, any per-item and aggregate limits applicable to the itinerary, packaging or segregation requirements, and instructions for check-in disclosure. If approval is denied, request the official reason in writing.
Documents to retain: emailed approval, screenshots of official web pages showing policy text, the product SDS, close-up photos of product labels showing UN number or hazard statements, flight number(s), and timestamps. Present these at check-in if asked.
Sample email body for carrier Dangerous Goods office: “Please confirm acceptance of the following product in the hold on flight [XX123] date [YYYY-MM-DD]: product name, manufacturer, net quantity per item [mL/g], total quantity [mL/g], UN number [if present], SDS attached. Request written confirmation of acceptance or prohibition and any special packaging/labeling required.”
Failure to obtain written approval may result in refusal to transport, seizure, fines, or delays. Retain all correspondence until arrival at the final destination.
Actions when pressurized spray products are refused, seized, or damaged at check-in or security
Request an on-the-spot written seizure or damage report, photograph the item and its packaging, and obtain staff names and an incident reference before leaving the screening area.
Immediate steps at the counter or screening point
- Ask security or airline staff for a written receipt that lists the item(s) removed, reason for removal, time, location, and the staff member’s name or badge number.
- Photograph the item(s) in situ, any visible damage to packaging or contents, the boarding pass, and the bag tag; take close-ups of serial numbers or labels.
- Request a supervisor if staff refuse to provide written documentation or clear explanation.
- If the product will be retained rather than destroyed, request details about where it will be stored, how long it will be held, and the process to retrieve or appeal.
- If leakage occurred inside baggage, note affected contents and request an on-site damage report listing items, estimated condition, and whether containment procedures were used.
Follow-up after leaving the airport
- File a formal claim with the carrier within the airline’s stated deadline (many carriers require damage claims within 7 days for visible damage; check the specific carrier policy and keep confirmation of submission).
- Submit copies of the seizure/damage receipt, photographs, boarding pass, bag tag, purchase receipts, and any serial numbers as supporting evidence.
- If items were removed by Transportation Security Administration or an equivalent authority, submit a complaint or inquiry to that agency’s customer service desk using the incident reference; retain all correspondence.
- Check travel insurance, homeowner’s or renter’s insurance, and credit-card purchase protection for reimbursement possibilities; include the official incident documentation in any claim.
- If the removed product was critical for the trip, purchase a non-pressurized alternative locally or at airport retail; for example, a durable sun shelter option: best vented patio umbrella.
- For personal-care devices that suffered contamination or minor damage, follow manufacturer cleaning guidance before reuse – see instructions on how to clean sonic scrubber heads: how to clean sonic scrubber heads.
- If the carrier denies liability, escalate with the airport operator, national aviation authority, or consumer-protection agency; include timelines, incident receipt, and all supporting files in the complaint.
Keep all original documents and photographs until claims and appeals are closed; maintain a single folder (digital and physical) with incident reference numbers and correspondence to streamline reimbursement or recovery requests.
FAQ:
Can I pack my deodorant and hairspray in checked luggage?
Yes — ordinary personal-care aerosols such as stick or spray deodorant, hairspray and shaving cream are usually allowed in checked baggage. Labels that state “flammable” or show a hazardous-goods symbol may be subject to extra limits or banned by some carriers, so inspect the product first. Close the cap, place the cans in a sealed plastic bag, cushion them so they cannot be crushed, and check your airline’s and the Transportation Security Administration (TSA) guidance before you fly.
Are there quantity or packing restrictions for pressurized cans in the hold?
Aerosols are treated as hazardous goods for transport, but consumer-sized toiletry aerosols are commonly accepted for checked bags under restrictions. Individual airlines and international rules set size and total-quantity limits, and some types of aerosol (for example, spray paints, fuel sprays or self-defence sprays) are prohibited. Pack cans in their original packaging when possible, tape or secure the nozzle to prevent accidental discharge, place them inside a sealed plastic bag, and cushion them to avoid impact. Because rules vary by carrier and by country, contact the airline and consult TSA or the relevant national aviation authority before you travel.
What are the risks if an aerosol can leaks or bursts in checked luggage, and what should I do if airport staff finds one?
Leaks or ruptures can soak clothing, stain items or create a slip or breathing irritation in a baggage compartment; if the can contains a flammable propellant, there is an added fire risk. Although modern cargo holds are pressurized and temperature-controlled, pressure and temperature changes can still affect weak or damaged cans. If screening personnel discover a prohibited or unsafe aerosol at the checkpoint they will usually remove and discard it; if an airline finds an item after check-in they may do the same. If a can breaks inside your bag and your belongings are damaged, report the problem immediately at the airline’s baggage service office, photograph the damage, keep the damaged item and any packaging, and retain receipts for claims. To reduce the chance of problems, avoid packing damaged or recalled cans, consider shipping hazardous aerosols by a specialist service if you need larger quantities, or buy replacements at your destination.
