Primary recommendation: Store unopened containers of alcoholic beverages between 24% and 70% alcohol by volume (ABV) in checked suitcases with a maximum of 5 liters per passenger; products exceeding 70% ABV are prohibited from air transport in both checked and carry-on items. Keep original retail seals intact and tag the piece as fragile when possible.
Packing protocol: wrap each container in absorbent material, place inside heavy-duty resealable plastic, then surround with clothing layers so the item sits centrally. Use a hard-sided case or dedicated inflatable/foam protectors for fragile containers and avoid overstuffing compartments that can compress and crack packaging.
Carry-on specifics: the 3-1-1 liquids rule applies – containers must be ≤100 ml (3.4 oz) and fit in a single clear quart-sized resealable bag; exceptions exist for duty-free purchases made after security if retained in tamper-evident bags with receipts. Expect additional screening and possible refusal at security checkpoints for items that trigger alarms.
Regulatory and customs notes: declare quantities above duty-free allowances and anticipate import duties or confiscation depending on destination. Many countries set age minimums and vary allowed volumes (common duty-free windows range from ~1 L to 5 L per adult). Verify airline policy, departure/arrival airport rules and official customs guidance before travel to avoid fines, delays or loss of the merchandise.
Airline and TSA rules: alcoholic beverages in checked and carry-on bags
Recommendation: place alcoholic beverages with 24–70% ABV (48–140 proof) in checked baggage only, limited to 5 liters per passenger in unopened retail packaging; containers over 100 mL must go in checked if on a U.S. domestic flight, while carry-on containers must follow the 3-1-1 liquid rule (≤3.4 oz / 100 mL each in one quart-sized clear bag); products above 70% ABV (over 140 proof) are forbidden in both checked and cabin luggage.
TSA (U.S.) numeric limits
- Carry-on: each liquid container ≤3.4 oz (100 mL); all containers must fit in one quart-sized clear, resealable bag (3-1-1 rule).
- Checked baggage: alcoholic beverages with ≤24% ABV (≤48 proof)–no TSA volume limit; any quantity allowed subject to airline checked weight limits.
- Checked baggage: alcoholic beverages >24% and ≤70% ABV (48–140 proof)–maximum 5 liters (1.3 gallons) per passenger in unopened retail packaging.
- Prohibited: alcoholic beverages >70% ABV (>140 proof) in both checked and carry-on.
- Duty-free: containers >100 mL purchased at airport must remain in secure tamper-evident bag (STEB) with receipt; rules vary for connecting flights and U.S. entry.
Packing practices and airline considerations
- Wrap each container in soft clothing, seal in zip-top plastic bags, and place inside cushioned section of checked baggage to reduce breakage risk.
- Keep receipts and STEB for duty-free items; if transiting through checkpoints that re-screen liquids, TSA 3-1-1 may apply unless bag remains sealed.
- International carriers and foreign airports may apply different ABV thresholds, per IATA/ICAO and local customs–verify airline policy and arrival-country import limits before travel.
- Excess weight or bulk may trigger checked-bag fees or refusal; declare large quantities at customs to avoid fines and confiscation.
- When in doubt, buy alcohol after security for carry-on consumption or ship via courier following hazardous-materials rules for high-ABV items.
Volume and alcohol-by-volume limits for checked bags and carry-on
Recommendation: For carry-on, keep each container at or below 100 ml (3.4 fl oz) and consolidate all containers into a single quart-sized (~1 L) clear resealable bag; duty-free purchases in sealed tamper-evident bags with receipts may exceed 100 ml but remain subject to airline and international transfer rules.
Checked bags: Alcoholic beverages up to 24% ABV (≈48 proof) are not subject to TSA quantity limits for checked carriage, though airline weight limits and destination import rules still apply. Products above 24% and up to 70% ABV (≈48–140 proof) are limited to 5 liters (1.32 US gallons / ~169 fl oz) per passenger and must be in unopened retail packaging. Items exceeding 70% ABV (over 140 proof) are prohibited from both checked and carry-on transport.
Carry-on specifics: all liquid containers must comply with the 3-1-1 rule – 3.4 fl oz / 100 ml per container, 1 quart-sized bag per passenger, 1 bag per passenger. Duty-free purchases sealed with a tamper-evident bag and a purchase receipt are often allowed through security; connecting flights that require re-screening may void that allowance, so confirm with the airline before departure.
Packing tips: keep receipts, retain original sealed retail packaging for high-strength spirits, pad containers inside checked bags to reduce breakage, and declare alcohol at arrival when required by local customs. For hard-sided options and protective cases consult best luggage beand.
Packing techniques to prevent breakage and leakage during air travel
Place glass containers upright in the center of a suitcase, surrounded by at least 8 cm (3 in) of soft clothing and wrapped with 2–3 cm (0.8–1.2 in) of bubble wrap.
Seal caps and threads with a strip of food-grade plastic wrap snugly applied over the closure, then secure that with 2–3 wraps of strong packing or electrical tape; alternatively use heat-shrink cap seals or parafilm for an airtight barrier.
Use double containment: slide each sealed container into a heavy-duty freezer zip-top bag, expel excess air before closing, then place that bag inside a second zip bag or an absorbent towel to capture any possible leakage.
Employ purpose-made protection: neoprene sleeves, inflatable bottle protectors, molded foam inserts or padded wine skins reduce shock transfer. For glass items, at least two independent protective layers are recommended (sleeve + bubble wrap or sleeve + molded foam).
Center placement matters: keep fragile containers at least 6–8 cm (2.5–3 in) from external seams, wheels and pockets; position so hard impacts hit outer areas first. Hard-sided cases with internal padding provide the best protection against crushing forces.
When decanting into travel flasks, leave roughly 15–25% headspace to allow thermal expansion; use containers with a gasketed screw cap and test each for leaks by inverting for 30–60 seconds before final packing.
Label the exterior with a small “fragile” tag and avoid overfilling the suitcase so internal items cannot shift; if possible, place packed suitcases on a flat surface and gently compress to confirm no movement before closing.
Customs, duty-free allowances and declaration when bringing alcohol across borders
Declare alcohol that exceeds the duty-free allowance at the first border control; keep purchase receipts, ABV labels and sealed duty-free bags available for inspection.
Typical allowances (examples)
European Union (arrival from non-EU): 1 L of spirits over 22% ABV OR 2 L of alcoholic beverages up to 22% ABV; additionally 4 L of still wine and 16 L of beer per adult (minimum age set by member state).
United States: 1 L per person aged 21+ generally exempt from federal duty; additional quantities are subject to federal duty and state taxes, with state rules affecting retail sale after entry.
Canada: For absences of 48 hours or more common exemptions are 1.5 L of wine OR 1.14 L of spirits OR 8.5 L of beer for eligible adults; different thresholds apply for longer stays and provincial age limits.
Australia: Typical duty-free concession is 2.25 L of alcoholic beverages for travellers aged 18+; amounts above that must be declared and are subject to customs duty and GST.
Declaration procedure and penalties
Use the declaration card or electronic kiosk to list quantities exceeding allowances and present receipts and original sealed packaging when requested. Customs will assess duty plus VAT/GST based on ABV and volume; tariff rates and tax calculations vary by destination. Splitting allowances among eligible adults is commonly accepted, while minors are not eligible for personal exemptions.
Failure to declare or false declarations often lead to seizure, fines, administrative penalties or criminal charges, plus inspection delays. When transiting, follow the intermediate country’s allowance and sealing rules; retaining sealed duty-free bags and receipts simplifies checks during connections.

Options for transporting high-proof spirits and courier shipping
Prefer licensed ground freight or specialist alcohol couriers with hazardous-goods capability for spirits above 70% ABV; common parcel services and passenger air carriage impose strict bans or severe limits.
Transport modes and carrier selection
Acceptable channels: licensed road freight providers, dedicated wine/spirits shippers, cargo-air freight via a dangerous-goods (DG) forwarder, and ocean freight with DG declaration. Major postal operators prohibit alcoholic beverages; major private couriers accept consignments only under formal alcohol-shipping agreements and typically restrict to ground networks. Freight forwarders able to file IATA/ICAO DGR or IMDG paperwork handle consignments that mainstream parcel networks reject.
Documentation, classification and numeric thresholds
Classify product by ABV: 24–70% ABV generally falls under Class 3 flammable liquids and can be transported with DG paperwork and packing limits; >70% ABV is frequently prohibited on passenger aircraft and refused by many couriers, but may move on cargo-only flights or by road/sea with full DG compliance. Applicable standards and references: IATA/ICAO DGR (air), IMDG Code (sea), ADR (road in Europe), 49 CFR DOT (US). UN numbers commonly applicable include UN1170 and UN1987; shipping papers must show proper shipping name, UN number, packing group, net quantity per inner receptacle and total net quantity.
Carrier requirements: shipper licensing, age-verification at delivery, commercial invoice with declared alcohol content, and where relevant an excise or alcohol transport permit. Postal channels such as the national mail service typically disallow alcoholic consignments.
Packing and labeling: use UN-spec inner receptacles and certified overpacks (eg. UN 4G fiberboard overpack for glass containers), absorbent material, caps sealed against leakage, and cushioning to meet the 1.2 m drop test. Affix Class 3 flammable labels, the UN number, orientation marking if required, and a hazardous-goods declaration when shipping under DG rules. State net volumes precisely and retain photos of packaging for claims.
Customs, commercial and insurance points: prepare commercial invoice with HS code (commonly 2208 for spirits), country-of-origin, alcohol percentage, and consignee license data for cross-border moves; bonded-warehouse solutions can defer excise until arrival. Purchase declared-value insurance that explicitly covers hazardous goods; standard carrier liability often excludes alcohol or damage from leakage.
