Carry‑on liquid rule: liquids and gels carried in the cabin must be in containers of 100 mL (3.4 fl oz) or smaller and fit inside a single transparent resealable bag. Larger volumes intended for the aircraft hold are subject to airline limits and international dangerous‑goods regulations.
Items typically permitted in stowed baggage: sealed bar soap, powdered laundry detergent, packaged disinfectant wipes, single bottles of non‑flammable liquid detergent in manufacturer packaging, and disposable mop pads. Containers should remain unopened where possible and be wrapped to prevent leakage.
Items commonly prohibited from both cabin and aircraft hold: aerosol sprays with flammable propellants, compressed gas cans, concentrated bleach and strong acids or alkalis (oven and drain cleaners), peroxide solutions above low concentrations, and any product labeled as corrosive, flammable, or oxidizing. Such goods are usually classified as dangerous and require professional shipment.
Practical steps: inspect product labels for hazard symbols and UN numbers; consult the carrier’s hazardous‑goods guidance and the IATA Dangerous Goods Regulations before travel; declare any questionable items at check‑in; retain original packaging and limit volumes. When uncertainty exists, arrange courier shipping as hazardous cargo or purchase equivalent products at the destination.
Permitted liquids and aerosols for hold baggage under TSA and IATA
Recommendation: Alcohol-based disinfectants between 24% and 70% ABV are permitted in hold baggage up to 5 L per person when carried in original retail packaging; products above 70% ABV are forbidden by IATA and TSA hazardous‑materials rules.
Aerosols labeled UN1950 (consumer or personal care aerosols with non‑flammable propellant) are generally accepted subject to quantity limits: maximum net per container 0.5 kg and aggregate net not to exceed 2 kg per passenger. Flammable aerosols, spray paints, and pesticide aerosols with hazardous propellants are prohibited.
Liquid classification rules that affect carriage: alcoholic liquids under 24% ABV face no special DG limits; 24–70% ABV are allowed in hold baggage up to 5 L per person in unopened retail packaging; >70% ABV are forbidden. Solvents, strong acids/alkalis, oxidizers and many bleach/oven‑cleaner formulations fall into prohibited or dangerous‑goods categories and must not be packed.
Packing requirements: leave products inside original, leak‑proof retail containers; fit aerosol caps or protective covers; place all liquid or aerosol items in sealed plastic bags and surround with cushioning to prevent rupture. Labeling must remain intact; if a product is non‑retail or larger than permitted limits, transport only as approved dangerous‑goods cargo with airline approval and proper documentation.
Operational note: airlines and national authorities may impose stricter limits than TSA/IATA; verify carrier policy before travel. For medical or workplace disinfectants that exceed passenger limits, arrange shipment as regulated cargo with the operator’s dangerous‑goods office.
How to pack and seal bleach, ammonia and concentrated solutions for hold baggage
Use triple containment and strict segregation. Place the original manufacturer bottle or a DOT/UN-rated inner container inside a heavy-duty resealable polyethylene bag with at least one absorbent layer (paper towels, cat litter or commercial spill pads). Put that assembly into a rigid, hard-sided plastic tub with a screw-top lid; seal the tub with tape. Store tubs in the center of the case, cushioned by garments to minimize impact forces.
Cap and neck protection: Wrap threaded caps with PTFE (plumber’s) tape, then apply a tight-fitting shrink band or heat-shrink sleeve if available. For pump dispensers, remove the pump and pack it separately in a bag. After sealing the cap, apply a strip of tamper-evident tape around cap-to-neck and over the seal bag closure.
Absorbent and secondary layer: Put at least one-inch layer of absorbent material beneath and around the inner bottle inside the resealable bag. If multiple bottles travel, wrap each individually and place into separate sealed pouches before grouping inside the rigid outer container; never pack bleach and ammonia together in the same pouch, tub or adjacent compartments.
Quantity and bottle condition: Favor minimal volumes–use travel-size containers (100–500 ml) whenever practical. Inspect bottles for rust, bulging, or hairline cracks; transfer to chemically compatible polyethylene or HDPE replacement bottles only if original container is damaged. Leave modest headspace (5–10%) to allow thermal expansion.
Labeling and segregation: Affix a clear external label on the rigid container stating contents (e.g., “sodium hypochlorite solution” or “ammonia solution”) and hazard class (corrosive/irritant). Segregate oxidizers, acids and organics from chlorinated and ammoniacal products by placing them in separate tubs; keep incompatible substances separated by a full compartment or bag.
Leak response and neutralization: Carry a small spill kit: nitrile gloves, absorbent granules, sealed disposal bag and safety goggles. For liquid leaks, ventilate the area, absorb with inert material and reseal contaminated absorbent in a sealed bag. Do not mix bleach and ammonia under any circumstances; mixing produces toxic gases. If in doubt or if a significant leak occurs, contact airline ground staff or airport hazardous-materials personnel for handling.

Quantity and container limits for flammable or pressurized household chemical products
Limit pressurized aerosol cans to a maximum net content of 500 mL (0.5 kg) per can and an aggregate net quantity of 2 kg per passenger in the aircraft hold; aerosols with flammable propellants and disposable gas cartridges are prohibited.
Non‑flammable aerosols and alcohol solutions
Consumer aerosols that are non‑flammable (UN 1950, non‑hazardous contents) must remain in original retail packaging, have valve protection caps, and be free of leaks. Each unit: ≤500 mL (≤500 g net). Total aggregate per passenger: ≤2 kg net. Alcohol‑based solutions intended for personal use that contain 24–70% alcohol by volume are accepted in the aircraft hold in retail packaging up to 5 L per passenger; concentrations >70% are forbidden without dangerous‑goods documentation.
Flammable liquids, gases and pressurised containers
Highly flammable solvents, fuels, paint thinners, butane/propane cartridges, oxygen canisters and other pressurised flammable cylinders are not permitted in passenger baggage under ICAO/IATA rules and most national regulations. Any item classed as a listed dangerous good (flammable liquid UN 1993, flammable gas) requires commercial dangerous‑goods packaging, labeling and airline acceptance; informal transport in personal baggage is not allowed. For shipment under dangerous‑goods procedures, follow IATA DGR packing instructions, use UN‑rated containers, and obtain carrier approval in advance.
Packing recommendations: retain original sealed containers, place valve caps and protective covers over nozzles, place each item in a sealed plastic bag, pad with absorbent material, stow upright inside a hard container or between soft goods to prevent impact, and declare to the airline when aggregate quantities approach regulatory limits or when items carry a hazardous‑goods label.
Labeling, declaration and airline notification for large or commercial sanitation products
Declare bulk or commercial quantities as dangerous goods and book through the carrier’s Dangerous Goods Office before tendering to the airport. Large volumes or industrial-grade formulations must move as cargo under IATA/ICAO rules; passenger aircraft carriage is typically prohibited without explicit operator approval.
Required documents: attach a current Safety Data Sheet (SDS), a completed and signed Shipper’s Declaration for Dangerous Goods (when applicable), the air waybill with UN number and proper shipping name, and any national export/import permits or biocide registrations. The shipper’s declaration must include a 24‑hour emergency contact phone number.
Minimum shipment data to provide to the carrier: UN number, proper shipping name, hazard class/division, packing group, net quantity per package, number of packages, gross weight, package dimensions, packaging specification (UN‑approved code if used), and intended routing. Carriers will not accept incomplete declarations.
Labeling and markings: apply GHS pictograms where applicable plus the appropriate IATA diamond hazard label(s) showing class and division. Affix the UN number and proper shipping name on the package exterior, the shipper’s name/address, orientation arrows for liquid packages, and the “CARGO AIRCRAFT ONLY” label when required by IATA for that substance. Use weather‑resistant labels at least to the size and colour standards specified in IATA DGR and place marks on two opposing sides.
Package marking tips: mark net quantity per package (e.g., “Net 5 L”), include the packing instruction reference (PI) on the waybill or declaration when requested, and ensure UN packaging performance tests are documented for bulk drums or jerricans. For aerosols and pressurized items, include the applicable UN number (for example UN1950 for aerosols) and the correct hazard label.
Advance notification and timing: notify the carrier’s Dangerous Goods Office at least 48–72 hours before planned tender for commercial consignments; many operators accept shorter notice for regular customers but written acceptance is required. Obtain a written booking confirmation that explicitly states the carrier’s acceptance of the DG shipment and any special handling instructions.
On‑site acceptance procedures: present original DG documentation and SDS at tender. Expect a carrier acceptance check that covers package integrity, markings, label placement, and documentation accuracy; non‑compliant consignments will be refused and may incur re‑packaging or disposal charges.
Regulatory cross‑checks: verify ICAO TI, IATA DGR and the applicable national civil aviation authority rulings for origin/destination countries. For disinfectants with active biocide ingredients, check customs and health authority permit requirements before shipment.
Failure to declare: undeclared hazardous consignments create legal liability, heavy fines, shipment seizure and denial of future carriage; maintain copies of all declarations and carrier acceptances for at least the retention period required by local regulations (commonly two years).
Prefer solids, powders and pre-moistened non-flammable wipes; pack each item in inner zip-seal bags with an absorbent pad and place inside a rigid case for transport in the aircraft hold.
Recommended solid and non-liquid options: bar soap (wrap in vacuum or zip-seal bag), sodium percarbonate oxygen-bleach powder (store in original sealed container), powdered laundry detergent (keep under 2 kg per container for personal use), pumice or scouring blocks, baking soda (sodium bicarbonate) in small sealed tubs, enzyme laundry powder sachets, solid dishwashing blocks, dry abrasive pads, and alcohol-free antiseptic wipes containing benzalkonium chloride. Avoid single-dose liquid pods; their concentrated liquid cores are prone to rupture.
Packing protocol for non-liquid agents
Place each item in two layers: an inner zip-seal bag plus a second seal (another bag or a heat-sealed pouch). Add one absorbent pad per bag for powders that could clump or leak. Store all sealed bags inside a rigid case or hard-shell suitcase center compartment, surrounded by soft clothing as shock absorption. Label containers with product name and weight. Keep receipts and original manufacturer packaging for any powder/solid over 1 kg to demonstrate personal-use intent if queried.
| Product type | State | Fire/pressure risk | Packing tip | Best use |
|---|---|---|---|---|
| Bar soap | Solid | Low | Vacuum-seal or double zip-bag | Handwashing, degreasing |
| Powder oxygen bleach (sodium percarbonate) | Powder | Low (oxidizer hazard if mixed with strong acids–keep separate) | Original container inside zip-bag; absorbent pad | Whitening, stain removal |
| Powder laundry detergent | Powder | Low | Seal in tub or bag; keep under ~2 kg per item | General washing, deodorizing |
| Pre-moistened alcohol-free wipes | Moistened fabric (non-flammable formula) | Low (check ingredients) | Keep in factory-sealed packs or double-bag | Surface sanitation without liquid bottles |
| Pumice/scouring blocks, abrasive pads | Solid | Low | Wrap in paper and bag to contain dust | Removing tough deposits, scouring |
Handling powders and concentrated solids
Keep powders dry and separate from any acids or strong oxidizers. If a powdered oxidizer is necessary, pack in original, clearly labeled packaging and isolate from clothing and electronics. For transport of bulky refrigeration items or frozen agents related to maintenance operations, consult the equipment review and specifications at are statesman freezers any good before shipment planning.
What to expect if prohibited household chemical items are discovered at check-in or security
Declare the item immediately to airline or security personnel; anticipate seizure, inspection and possible penalties.
- Immediate actions by staff
- At ticket counter: agent may refuse acceptance, require removal from the transport process, or redirect to a hazardous-materials desk.
- At security checkpoint: Transportation security officers typically seize and dispose of prohibited items on the spot; secondary screening and bag opening are common.
- Security and law-enforcement involvement
- Items that spill, emit fumes, or resemble explosives/oxidizers often trigger law-enforcement response and explosive-trace or chemical-analysis testing.
- Local police or federal officers may interview the passenger and log the incident; detention is possible if intent or recklessness is suspected.
- Disposition of the item
- Most prohibited household chemicals are permanently confiscated and destroyed; retrieval at destination is rarely offered.
- Occasional alternatives: personal disposal at a designated facility, or arranging shipment via a licensed hazmat carrier at passenger’s expense–requires proper packaging, labeling and permits.
- Travel impacts
- Delays while officers inspect bags and question passengers; missed connections or denied boarding possible if removal cannot be completed before departure.
- For international travel, customs agencies may impose additional holds, fines or refuse entry if the item violates import restrictions.
- Documentation and follow-up
- Request a written seizure receipt or property tag number and the name/badge of the officer who handled the case.
- Photograph the item and its packaging before handing it over when safe and allowed.
- Contact the airline’s hazardous-materials office or the checkpoint authority for appeal, claim or return options; retain boarding pass and incident paperwork.
- Regulatory and financial consequences
- Civil fines or administrative penalties may apply for transporting prohibited hazardous goods; criminal charges can arise if malicious intent or gross negligence is suspected.
- Commercial quantities or undeclared hazardous items carried for sale often trigger regulatory enforcement, cargo rejection and larger penalties under DOT/IATA rules.
When an SDS (safety data sheet) exists for the product, present it to staff; properly documented chemical shipments handled as cargo require prior airline approval and specific packaging, labeling and paperwork.
