Limit to 12 oz / 350 mL (≈340 g) per passenger in carry-on; quantities above that should be placed in checked baggage or split among travelers. This threshold matches Transportation Security Administration (TSA) screening guidance for dry, granular substances and is widely applied by airport security staff in the United States.
Domestic guidance: roasted grounds are generally permitted in both carry-on and checked bags, but containers >12 oz/350 mL brought into the cabin may require secondary screening and could be denied if screening cannot verify contents. Checked baggage usually has no specific weight cap for roasted products, yet strong sealing and durable packaging are recommended to prevent leakage and odor transfer.
International travel notes: biosecurity and customs rules vary. Roasted and roasted-ground products are usually acceptable, while green (unroasted) beans or raw plant material are often restricted or prohibited in countries with strict agricultural controls (for example, Australia and New Zealand enforce stringent declaration and inspection requirements). Verify destination customs and airline policies before departure.
Packing and screening recommendations: use original factory-sealed packaging or vacuum-sealed, airtight tins; weigh containers before arrival to ensure compliance with the 12 oz/350 mL carry-on threshold; place a small portion in a clear resealable bag for easy inspection; label the package clearly. If secondary inspection is requested, allow security to open the container for verification; if denied entry to the cabin, move the item to checked baggage or dispose of it at the checkpoint.
US TSA rules: quantity thresholds and screening for ground-beverage products
Limit ground-beverage material in carry-on to 12 oz (350 g) or less; quantities above that will likely trigger additional screening and may be required to be placed in checked baggage.
Quantity thresholds
Federal Transportation Security Administration guidance uses 12 oz / 350 mL as the practical threshold for granular or powdered consumables in cabin bags. Items at or below this threshold are generally screened by X‑ray and cleared quickly. Items exceeding 12 oz are subject to enhanced inspection, which can include visual examination, manual handling, and trace or chemical testing; unresolved items may be denied access to the cabin.
| Amount | Typical TSA response | Recommended action |
|---|---|---|
| ≤ 12 oz (≤ 350 g) | X‑ray screening; may require separate bin; usually permitted | Keep in original container or clear resealable bag; place in bin during screening |
| > 12 oz (> 350 g) | Enhanced screening (visual/manual/swab); possible transfer to checked baggage or refusal | Pack in checked baggage when feasible; if carried onboard, allow extra time for inspection |
| Checked baggage (any amount) | Generally permitted, subject to airline rules and international restrictions | Seal in airtight container; label contents; secure checked case with visible tag such as best luggage tags for men |
Screening process and practical tips
Expect X‑ray analysis first; if imaging is inconclusive, TSA officers may conduct a swab for explosives trace detection or open packaging for visual inspection. Present original retail packaging when possible and provide brand/product name if asked. Use clear resealable bags to contain spillage during inspection. For international itineraries, check arrival country rules and airline policy ahead of travel. When in doubt, place large bulk quantities in checked baggage or ship via courier to avoid on‑site disposal.
Airline and country-specific bans: checking carrier and destination restrictions
Confirm airline and destination rules before departure: review the carrier’s “prohibited items” and “conditions of carriage” pages and the destination customs/inspection website; if any text is ambiguous, request written confirmation from the airline or a customs authority.
Priority sources: use the destination’s official agency (examples: Australian Department of Agriculture, Fisheries and Forestry at agriculture.gov.au; New Zealand MPI at mpi.govt.nz; UK guidance at gov.uk/bringing-food-into-uk; US Customs and Border Protection at cbp.gov; Singapore Food Agency at sfa.gov.sg) and the specific carrier’s online rules (search the airline name + “prohibited items”). International Air Transport Association (IATA) pages may provide additional airline policy links.
Packaging and documentation recommendations: keep commercial seal and original labeling, retain purchase receipts, and carry a clear statement of contents and country of origin. For amounts beyond personal-use norms or for resale, obtain an import permit and a phytosanitary certificate and arrange customs brokerage in advance.
Actions on arrival: declare all food or plant-derived goods on arrival forms where required. Undeclared items can be seized, treated, or destroyed; holders may face processing delays, fines, or returned consignments. When uncertainty remains, prefer checked bags or commercial shipment with clearance rather than cabin carriage of fine dry substances, and capture written pre-approval from the carrier.
For cleaning travel containers, seals and any reusable storage accessories consult how to clean sonic scrubber heads before reuse to avoid contamination and inspection issues.
Pack ground roast into clear, resealable bags, label with product name and net weight, then place inside a hard-sided pouch
Use original sealed retail packaging whenever available; if repackaging, transfer contents into transparent zip-lock bags (1 L / quart size), remove excess air with a hand pump or vacuum sealer, then heat-seal a second layer to form a dust-free block that resists spillage.
Packing steps
- Portion into multiple small packets rather than one large bag to reduce visual ambiguity and speed inspection.
- Affix printed labels to each packet: product name, roast date, net weight in grams, country of origin and batch/lot number.
- Place sealed packets into a rigid, crush-resistant container (plastic jar or metal tin) and add a silica packet to control moisture; wrap the container in a clear outer pouch for screening visibility.
- Include a photocopy or printout of the original purchase receipt or the product’s manufacturer webpage to show provenance during questioning.
Minimize dust and facilitate inspection
- Prefer whole beans over ground when feasible; intact beans produce less airborne particulates and are visually distinct.
- Compress contents into flat, solid shapes before sealing to avoid loose dust that triggers secondary screening.
- Avoid opaque foil bags or unbranded opaque containers that obscure contents on X-ray images.
- Keep all packets together in an accessible pocket – padded camera inserts work well for flat, protected storage: best messenger bag camera inserts.
If asked by security officers, present sealed packets and the receipt/printed product page immediately; keep containers closed unless an officer requests opening for inspection.
Customs declaration and quarantine considerations when bringing ground-bean products abroad
Declare all ground-bean and instant-ground items on arrival/entry forms and to border officers; undeclared plant-based goods commonly result in seizure, administrative fines, forced disposal and possible criminal charges.
Green (unroasted) beans are generally treated as raw agricultural material: most destinations require a phytosanitary certificate and, in many cases, an import permit before arrival. Roasted and instant formats are usually permitted for personal use provided they are free of plant debris, pests and soil and are declared at the border.
Quarantine inspection procedures frequently include X-ray screening, manual opening and visual inspection, and in-situ swabbing or laboratory testing for pests and pathogens. Items assessed as high risk may be subject to treatment (heat, irradiation) or ordered destroyed; treatment and disposal fees can be billed to the traveller or shipper.
Personal-use quantity thresholds vary by country; customs authorities commonly treat small amounts as personal consumption (typical practical range: 1–5 kg), while quantities above that are handled as commercial imports and require invoices, commodity declarations, duty payments and import licences. Declare exact weights and retain purchase receipts to demonstrate non-commercial intent.
For planned consignments or gifts, obtain exporter-issued phytosanitary documentation for green beans and check destination regulations in advance via official customs/biosecurity websites. When importing commercially, use formal import channels and a customs broker to arrange permits, certificates and any required pre-entry treatments.
High-biosecurity jurisdictions (examples: Australia, New Zealand) enforce strict controls: always declare plant-derived products on arrival cards, expect mandatory inspection, and do not rely on verbal statements alone–failure to comply there commonly leads to immediate confiscation and fines.
FAQ:
Can I carry ground coffee or instant coffee in my hand luggage?
Yes. Dry coffee—ground, instant or whole beans—is generally allowed in carry-on bags. Security staff may ask to inspect it separately or open sealed packs for X-ray checks, but the powder itself is not treated like liquids. Rules vary by airport, so allow extra time at screening and keep coffee in its original packaging or a clearly labeled container to speed up checks.
Are there quantity limits for powdered coffee in carry-on luggage?
In the United States, powders over 12 oz (about 350 mL) carried in hand luggage may need to be placed in a separate bin for screening and are subject to additional inspection. Other countries do not always use the same threshold: some airports have similar limits and others simply let officers decide on screening needs. If you plan to bring a large bulk, consider putting some in checked baggage or checking the specific airport and airline guidance before travel.
Could airport security confiscate my coffee grounds?
Yes, that can happen. If security cannot properly screen the powder or suspects it might be a prohibited substance, they may open the package, swab it, or ask you to discard it. Using factory-sealed packets or keeping smaller quantities in clear containers reduces the chance of problems. If you are traveling through multiple countries, variability in security procedures can increase the chance of additional checks.
Can I take coffee pods or single-serve sachets in my carry-on?
Single-serve instant coffee sachets and sealed pods that contain dry grounds are usually permitted in hand luggage. Pods filled with liquid (for example some pre-brewed coffee capsules) fall under liquid rules and may be restricted by the 100 mL limit for carry-on. If pods are vacuum-sealed and dry, they typically pass screening with no issue, though officers may still inspect them.
