Recommendation: Do not place fresh meat, dairy or uncooked fruit in your suitcase when flying to Australia, New Zealand or many countries in Asia; these jurisdictions routinely confiscate such items and may issue fines. Prefer commercially sealed, shelf-stable provisions for international trips, or carry medically necessary perishables in the cabin with documentation.
For flights originating in the United States: solid snacks and commercially packaged items are permitted in both cabin and the aircraft hold. Liquids, gels and aerosols in hand baggage must comply with the 3-1-1 rule – containers no larger than 100 ml (3.4 oz) placed in a single clear quart‑size bag. There is no 3-1-1 limit for items stored in the hold, but flammable substances and certain compressed gases are prohibited; always check your airline’s list of dangerous goods before packing.
Customs restrictions differ dramatically by destination. Australia and New Zealand enforce near-complete bans on fresh produce, meat and dairy; the United States prohibits many uninspected meat products and live plants; the European Union applies variable rules per member state. Before departure, consult the destination’s agriculture or customs website and declare any agricultural items on arrival forms to avoid penalties and seizure.
Packing recommendations: vacuum-seal perishables, freeze before departure and use rigid, insulated containers for the hold. If using dry ice, obtain airline approval and follow IATA rules – generally up to 2.5 kg per passenger when properly packaged, ventilated and labeled. Do not place spare lithium batteries inside coolers intended for the hold; spare cells must be carried in the cabin with terminals protected and individual packaging capped.
Practical checklist: 1) Verify airline policy and destination customs pages; 2) choose commercially sealed or shelf-stable products where possible; 3) vacuum-seal and label perishable items, declare them on arrival; 4) seek airline approval for dry ice or active refrigeration devices before departure; 5) carry spare batteries and critical refrigerated medicines in the cabin with medical documentation. Follow these steps to reduce the risk of confiscation, fines or safety-related refusals at the gate.
Allowed solid and dry items in hold baggage
Pack commercially sealed, shelf-stable provisions in their original labeling and store them inside hold baggage; declare any meat, dairy or plant-derived products to customs at arrival.
Typical permitted items
Commercial snack packs: biscuits, crackers, cereal bars; confectionery and chocolate; dried fruit, nuts and seeds; jerky and cured meats if vacuum‑sealed/retail‑packaged; hard and waxed cheeses; instant powders (coffee, powdered milk) subject to destination quantity limits; spices, dried herbs, granola, dry cereals, baking mixes and prepackaged baked goods.
Packing and regulatory tips
Keep original packaging and receipts, vacuum‑seal or double‑bag items prone to odor or crumbs, and cushion glass jars to avoid breakage. Refrigeration-dependent items are not recommended for transit without proper coolers. Verify destination agricultural rules – many countries prohibit fresh fruit, vegetables, raw meat and unpasteurized dairy; undeclared restricted items may incur fines or destruction. Check airline weight limits and the destination border authority website before departure.
Rules for transporting liquids, sauces and canned goods in hold baggage
Store sauces and loose liquids in screw-top containers with chemical-resistant seals, place each container inside two sealed zip bags, then position those bags inside a rigid, leak-proof inner box at the suitcase core; freeze high-water-content sauces when possible to solidify and reduce leak risk.
Alcohol limits follow IATA guidance: beverages 24–70% ABV allowed up to 5 L per passenger if in original retail packaging; beverages above 70% ABV are prohibited from the aircraft hold. Aerosols and flammable liquids face strict restrictions or prohibitions – consult the carrier’s dangerous-goods table before packing.
Metal tins and glass jars are vulnerable to pressure and impact: leave minimal headspace in jars, secure lids with tamper-evident tape, wrap each item in bubble wrap, and surround with absorbent pads; place heavy tins close to the suitcase frame and wheels to stabilize weight distribution and reduce rupture risk.
Weight policy matters: many carriers set a 23 kg (50 lb) allowance per economy piece and a 32 kg (70 lb) limit per heavy piece; overweight charges apply per kilogram or per additional piece. Tally total mass of jars, bottles and cans against the ticketed allowance before departure.
Customs and biosecurity rules vary by destination: commercially sealed and labeled canned products usually clear inspection, while homemade sauces, dairy-based items and meat-derived liquids frequently require declaration or are forbidden. Declare regulated items on arrival to avoid seizure and fines.
Packaging best practices: vacuum-seal sauces when possible, use heat-shrink bands or screw-cap tamper seals, place each sealed bundle inside an outer waterproof liner, and include a single absorbent pad per bundle to trap any leakage during transit.
Battery-powered appliances containing lithium packs require battery removal and carriage according to airline rules; large external batteries for garden tools often face prohibition or special handling – verify with the carrier and review product guidance such as best cordless lawn mower for battery life.
Choose protective carriage gear: a hard-shell case or padded insert reduces impact damage to cans and jars; consider quality sets designed for frequent overseas travel when transporting heavy canned loads – see best luggage sets for frequent international travelers. Keep a compact umbrella in hand baggage for wet transfers: best umbrella for walkers.
Customs and agricultural restrictions for cross-border edibles
Declare all animal-origin products, fresh fruit, vegetables, seeds, live plants, soil, dairy, meat and honey on your arrival card; failure to declare commonly leads to seizure, mandatory treatment or fines.
Agencies to consult before travel: USDA APHIS and US Customs and Border Protection (USA), Department of Agriculture, Water and the Environment (DAWE/DAWR) and Australian Border Force (Australia), Ministry for Primary Industries (MPI, New Zealand), DEFRA and UK Border Force (United Kingdom), and national plant-health services within the EU. Search the destination agency site for “phytosanitary certificate”, “import permit” or “biosecurity requirements”.
Frequently prohibited items: fresh fruit and vegetables, raw or undercooked meat and meat products, unpasteurised dairy, live insects, seeds and propagative plant material, soil and compost, untreated wood and wild-harvested mushrooms or herbs. Often restricted items (may require permits or certificates): honey, commercial pet treats containing animal protein, seeds for planting, nursery stock and cut flowers.
Documents commonly required for permitted imports: phytosanitary certificate issued by the exporting country’s plant health authority, veterinary/animal health certificate for animal-origin goods, and an import permit issued by the destination authority. Request certificates at least 2–4 weeks ahead for commercial consignments; exporters or sellers usually initiate issuance.
At-border procedure: declare items on the arrival declaration, present boxed/packaged goods and certificates at inspection, and follow officer instructions. If an item is non-compliant it will be either seized and destroyed, treated (fumigation, irradiation, heat treatment) with fees charged to the traveller, or returned to sender. Penalties range from administrative fines to criminal prosecution for intentional smuggling.
Packing and labeling guidance: keep products in original, unopened commercial packaging with ingredient panels and country-of-origin labels; retain purchase receipts and seller contact details; remove all soil from potted plants and roots; avoid home-canned or homemade preserves unless accompanied by explicit import approval.
Country-specific practices: Australia and New Zealand enforce near-zero tolerance and use biosecurity detector dogs and strict disposal rules; the EU allows intra-EU movement of many plant products with a plant passport but imposes phytosanitary controls for regulated pests; the UK requires certificates post-Brexit for certain plant and animal products; the USA requires declaration and inspection, with APHIS handling plant-health permits.
Quick checklist before departure: 1) make a complete inventory of consumables and plant items; 2) check the destination authority website for permit/certificate requirements; 3) obtain any needed phytosanitary or veterinary documents; 4) keep original packaging and receipts accessible; 5) declare all items on arrival; 6) if unsure, declare–inspection avoids heavier penalties.
Packing techniques to prevent spills, odors and contamination in hold baggage
Double-seal perishables: place each item in a heavy-duty zip-top freezer bag (≥4 mil), press out air, then vacuum-seal or add a second airtight bag with its seal folded and taped.
Use leakproof rigid containers for jars and liquids-prone items: choose plastic screw-top containers with silicone gaskets or food-grade polymer jars; wrap lid threads with PTFE (plumber’s) tape and secure with a layer of clear packing tape around the circumference.
Inside-container absorbents: line the bottom of each container with an absorbent pad (surgical or pet-training pad) or several thick paper towels. For raw proteins place an extra pad under the inner bag to trap exudate; replace pads at destination.
Outer containment: box sealed items inside a hard plastic tote or small cooler with snap lid. Seal tote with tape and place in the centre of the hold bag surrounded by soft garments to form a protective cushion and reduce lid stress.
Odor control: vacuum-seal aromatic items or enclose in smell-proof Mylar bags. Add 30–100 g activated charcoal sachet per compartment or a 50 g baking-soda pouch for milder odors. Avoid loose powders that can spill.
Shock and puncture protection: wrap glass or thin-walled containers in bubble wrap (3–4 layers) and place vertically in a molded foam or clothing “nest.” Keep cans and tins away from seam edges and wheels to prevent crushing.
Temperature-sensitive items: use frozen gel packs that are solid at packing; place them outside inner sealed bags so any melt is contained by outer absorbents. For dry ice: carrier approval required; limit generally 2.5 kg (5.5 lb) per passenger, package must vent CO₂ and be labeled UN1845 / Class 9.
Cross-contamination prevention: store raw and ready-to-eat items in separate sealed compartments or color-coded bags; label compartments “raw” and “ready-to-eat.” Always place raw items below or isolated from items that will be consumed without heating.
Spill mitigation checklist for final packing: double-bag each item, add absorbent pad, place in rigid tote, cushion with clothing, include an odor absorber, tape tote shut, and affix a “perishable”/“fragile” sticker. Keep a small roll of heavy-duty bags and extra absorbent pads accessible at destination for any cleanup.
Transporting perishables: using ice packs, frozen blocks and safe time windows
Use at least two 500 g frozen gel packs plus an insulated hard cooler to keep refrigerated perishables below 5°C for 12–24 hours in temperate conditions; for 24–48 hours use three 1 kg frozen blocks or one 2 kg block with a high-performance foam chest.
- Cold agents – quick specs and when to use
- Frozen gel packs (250–1000 g): flexible, resealable, freeze at −18°C in a standard freezer; two 500 g packs suit short trips (up to ~24 h) in a compact cooler.
- Frozen water blocks / ice bricks (0.5–2 kg): higher thermal mass per kg than gel packs; one 1 kg block outperforms a 1 kg gel pack for multi-day cold retention.
- Phase change materials (PCMs) with melt points 0–5°C: engineered to hold a stable refrigerated temperature longer than generic gels; choose PCM rated for target temp.
- Dry ice (solid CO2): keeps contents frozen (< −18°C). Typical passenger limits are around 2.5 kg (5.5 lb) per person and requirements vary by carrier – package for venting and label with UN1845 and net weight.
- Target temperatures
- Refrigerated perishables: maintain <4°C (ideally 0–4°C).
- Frozen perishables: maintain ≤ −18°C for product safety and texture.
- Estimated safe time windows (ambient 20–25°C)
- Compact soft cooler + 2×500 g gel packs: 8–12 hours, temperature may approach 5–8°C near end of window.
- Rigid foam cooler (thick walls) + 3×1 kg frozen blocks or PCM: 24–36 hours while keeping center <4°C.
- High-performance vacuum-insulated cooler + 2–3 kg frozen blocks: 36–48 hours for refrigerated targets.
- Dry ice (1–2.5 kg) in a ventilated insulated container: keeps items frozen for 24–72 hours depending on container size and packing density; more dry ice extends duration but triggers stricter carrier limits.
- How to size cold mass for duration
- Decide target temperature and maximum acceptable duration.
- For each 12–24 h interval at room temp, allocate ~1–2 kg of frozen mass (actual varies with cooler R-value).
- Use thicker-walled coolers and reduce headspace to improve efficiency – less air volume equals longer retention.
- Monitoring and verification
- Place a single-use temperature indicator or electronic data-logger inside the cooler center; record minimum/maximum values on arrival.
- Thermometer strips (adhesive) cost-effective for one-way trips; choose indicators with a trigger point at 4°C for refrigerated goods or −18°C for frozen items.
- Operational tips
- Pre-freeze gel packs and chill the container before loading to avoid initial heat load.
- Pack perishables in sealed, leakproof containers and surround with frozen blocks rather than placing all cold on one side.
- Place absorptive material (paper towel) beneath to capture melt; keep items away from external walls where heat ingress is highest.
- When using dry ice, allow venting space, wrap in paper to reduce direct contact burn, and label package per carrier rules.
- For trips longer than available passive cold duration, use a refrigerated courier or arrange a cold-chain service instead of relying on increased frozen mass alone.
- Regulatory and carrier notes
- Dry ice use and maximum net quantity vary by airline and country; verify carrier-specific limits and declaration requirements before travel.
- Some airlines restrict refrigerants or refuse containers that may leak or emit gases in the hold compartment; check the carrier’s hazardous-materials guidance.
Airline-specific policies, required declarations and possible fees for culinary items
Contact the carrier at least 72 hours before departure and declare any perishables or commercial quantities at check-in; undocumented items may be refused acceptance or offloaded by ground staff.
United States federal rule for alcoholic beverages: 24–70% ABV is permitted in baggage stowed in the aircraft hold up to 5 L per passenger in unopened retail packaging; >70% ABV is prohibited. Individual carriers may have stricter limits or deny transport of high-volume quantities.
Typical carrier practice: domestic US airlines (American, Delta, United) generally allow sealed solid provisions and canned goods in the aircraft hold without item-specific charges, but standard bag fees and overweight/oversize surcharges still apply – first bag commonly $30–35, second bag $40–45; overweight fees for 23–32 kg (51–70 lb) typically $100–200, and for >32 kg (>70 lb) $200–400. Long-haul international carriers (Lufthansa, Air France, British Airways, Emirates, Qatar) often include one piece on many fares or apply per-piece pricing; transporting perishables may require pre-approval or cargo booking and can trigger handling surcharges ranging from $50 to several hundred dollars depending on required temperature control.
Required declarations and documentation: for animal-origin or plant-origin items, present export/import permits, health certificates, phytosanitary certificates or manufacturer invoices at check-in when requested. For commercial quantities carry a commercial invoice and airway bill number; single-use personal portions typically only require verbal declaration to the agent. Failure to produce certificates can result in confiscation, quarantine, fines or denial of carriage.
Large quantities or temperature-controlled shipments are frequently routed via airline cargo rather than passenger baggage. Cargo tariffs commonly consist of a base handling fee ($30–$150), a cold-chain surcharge ($30–$200), plus per-kilogram freight. Live seafood, plants or bulk dairy/meat almost always require cargo booking, pre-approval and export/import paperwork.
Practical checklist: call the carrier and record agent name and reference; verify per-passenger volume limits for liquids and alcohol; obtain and carry required certificates and invoices; label packages with content description and phone number; arrive early to declare items at check-in; be prepared to pay standard baggage fees, overweight/oversize charges or special handling/cargo surcharges if applicable.
