Regulatory baseline: U.S. Transportation Security Administration and many international screening authorities treat dry foodstuffs and granular mixes differently from liquids. Items with a volume greater than 350 mL (about 12 fl oz) carried in the cabin are subject to additional inspection; failure to clear that inspection can result in refusal to board with the item or its removal at security.
Practical packing steps: keep the drink mix in original, sealed commercial packaging with a clear ingredient label; place each container inside a transparent resealable bag for easy handling; separate any containers above the 350 mL threshold into checked baggage. If multiple small containers are needed, split the total amount into units under 350 mL to reduce the chance of extra screening.
At the checkpoint: present the container(s) separately on the X‑ray belt when requested and be prepared for physical inspection. Carry proof of purchase or an ingredient list for unfamiliar brand formulations; airline or airport staff may request clarification for large or unlabelled quantities.
Exceptions and route-specific rules: infant nutrition mixes and medically prescribed dried formulations are generally permitted with supporting documentation–declare these items proactively. Rules vary by carrier and transit country; verify security guidance on the departure airport and airline websites before travel and, when in doubt, move bulk supplies into checked baggage to prevent delays.
Check airline and departure/arrival airport dry-mix rules before booking
Verify carrier and both departure and arrival airport security pages for rules on dry beverage mixes before purchasing tickets; if planned volume exceeds 350 mL (12 oz) for flights bound to the United States, plan to stow items in checked baggage or arrange shipping.
Where to verify
Open the airline’s “baggage” and “restricted items” webpages and search for terms like “powder-like,” “dry mix,” or “granular substance.” Consult the departure and destination airport security or operator sites for local screening procedures. Check official transport-security agencies (example: TSA for the US, CATSA for Canada, CAA for the UK) for published thresholds and special rules for international inbound flights. If transit involves a third airport, confirm rules for every transfer point.
Packing and documentation
Keep products in original sealed containers with ingredient lists and purchase receipts. Divide quantities into containers under 350 mL when carry-on carriage is preferred. For formula, medical supplements or prescription-related mixes, carry a physician’s note and original prescription. Expect enhanced screening: allow extra time at checkpoints, be prepared to move items to checked baggage, ship via courier for bulk amounts, or surrender the items if required by security staff.
TSA and security screening: what triggers tests and when dry mixes may be denied
Keep dry beverage mixes in their original, sealed packaging and limit any carry-on portion to 12 oz (350 mL); larger quantities should go into checked baggage to reduce the chance of secondary screening or disposal.
- Common triggers for enhanced screening
- Container volume exceeding 12 oz (350 mL) or bulky loose containers
- Opaque, unlabeled, unsealed or homemade packaging
- Loose residue or visible dust inside carry items
- Multiple similar bulk containers grouped together
- X‑ray images that do not clearly identify the material (ambiguous shapes or densities)
- Random selection or intelligence-led alerts at the checkpoint
- Screening procedures likely to be used
- X‑ray inspection of the bag and contents
- Request to open the package for visual inspection and manual handling
- Swab sampling for explosive trace detection (ETD) and chemical analysis
- Field reagent tests or laboratory hold if identification fails at checkpoint
- Requirement to move the item to checked baggage or surrender it for disposal if it cannot be cleared
- When denial or disposal occurs
- If the item cannot be positively identified by X‑ray, swab or visual check
- When the owner refuses additional screening or to transfer the item to checked baggage
- If ETD or other on‑site tests suggest a prohibited substance
- If local airport authority or foreign security standards differ from TSA guidance and prohibit carriage
- Practical mitigation steps for fewer delays
- Carry single‑serve packets or keep quantity per carry bag under 12 oz (350 mL)
- Retain original retail seals and receipts; place items in a clear resealable bag for inspection
- Declare large or unconventional containers at the checkpoint before screening begins
- Accept relocating bulk items to checked baggage rather than refusing inspection
- Purchase in secure zone after screening when possible

Packing and labeling: retail packaging, resealable bags, and clear containers that pass checkpoints
Keep cocoa beverage mix in original, sealed retail packaging whenever possible; if opened, transfer single-serving portions into transparent, resealable bags or clear rigid jars labeled with product name and net weight.
Retail packaging
Leave barcoded boxes, foil pouches or factory-sealed canisters intact so barcode, ingredient list and nutrition label remain visible. Retain purchase receipt and keep multi-use packs divided into single-serve sachets before travel to reduce handling time during inspection. Prefer single-serve retail sachets for flights longer than four hours or multi-leg itineraries.
Resealable bags and clear containers
Use heavy-duty, transparent zip-top bags (freezer-grade preferred) or clear PET/HDPE jars with screw lids and wide mouths. Limit any single container to about 350 mL (≈12 fl oz) or less when possible; label each container with product name, net weight in grams and ounces, and date opened using a permanent marker or printed sticker. Double-bag small amounts and apply tamper-evident tape across closures. Avoid opaque or unmarked tubs – poorly labeled items increase the chance of secondary inspection or disposal. Store labeled containers in an easy-to-reach compartment of carry-on for quick presentation if requested.
Quantity limits and how to split cocoa mix between carry-on and checked baggage
Recommendation: keep the cabin portion ≤350 g (12 oz) per passenger; store all additional granulated cocoa mix in checked baggage, split into sealed units no larger than 1 kg each.
Practical splitting examples
Short flights: place 100–200 g in a small resealable pouch inside the carry-on; remaining supply in one or two sealed retail packs inside checked baggage. Long flights or multiple uses: allocate 300–350 g to the cabin and divide the remainder into 500 g–1 kg vacuum-sealed bags for checked bags. For group travel, distribute cabin allowances across passengers so each individual cabin packet stays ≤350 g.
Packing strategy and screening minimization
Use original retail packaging for checked items when available; if transferring, include an ingredient label and a printed purchase receipt inside the checked bag. Single large checked bundles (>1–2 kg) should be split into multiple sealed bags to reduce damage and simplify customs inspection. Place cabin packet near the top of the carry-on for quick access during security checks. If screening requests additional inspection, presenting a clearly labeled small sample helps speed resolution.
Checklist: cabin packet ≤350 g; checked packs 500 g–1 kg; retail labels or printed ingredient list; receipt inside checked baggage; distribute across passengers when needed.

Declare all edible dry mixes and cocoa-based drink mixes on customs forms; undisclosed items can be seized and may trigger fines or quarantine.
Ingredients that trigger agricultural or food-safety bans: milk solids and whey, dried milk derivatives, eggs, meat derivatives (gelatin, beef fat, poultry extracts), tree nuts and peanuts, sesame, seeds, unroasted cacao nibs, botanical extracts (herbs, roots, seeds), and undeclared dairy substitutes produced from regulated feedstocks. Any item listing these components on the ingredient panel should be treated as a potential biosecurity risk.
Country examples and likely outcomes
| Country / Region | Notable restrictions | Typical documentation or action required |
|---|---|---|
| Australia | Very strict: most animal products (including dairy and meat derivatives) and many plant materials must be declared and are frequently prohibited. | Declare on incoming passenger card; commercial product may still be refused; import permit/health certificate required for allowed animal-origin goods; expect inspection and disposal. |
| New Zealand | High biosecurity risk tolerance; dairy, meat, seeds, and certain dried botanicals usually refused or need clearance. | Declare; possible quarantine; import permits and MPI approvals needed for animal-origin items. |
| United States | Personal commercially-packaged dry mixes generally admissible but items with meat, fresh fruit, or soil are denied; dairy items inspected by USDA/FDA. | Declare all food; have receipts and ingredient lists; FDA/USDA inspection may occur; permits rarely issued for casual personal amounts. |
| Canada | Dairy and meat products from many countries restricted; seeds and raw botanical material may need phytosanitary certificates. | Declare; inspection by CBSA/CFIA; health or phytosanitary certificates sometimes required for imports beyond personal small quantities. |
| European Union / United Kingdom | Post-Brexit UK: most meat/dairy from outside GB prohibited. EU: member-state rules vary; many prohibit non-EU meat/dairy. | Check destination authority; commercially sealed items with EU/UK labeling fare better; health certificates for animal-origin goods from third countries. |
| China & Singapore | Strict controls on dairy, powdered dairy substitutes, and many botanical additives; undeclared animal-origin content often confiscated. | Import permit or health certificate often required; mandatory declaration; fines possible for non-declaration. |
Practical documentation and preparation checklist
– Always declare edible dry mixes and list ingredients on arrival card or electronic form. – Keep original, sealed commercial packaging with clear ingredient list and manufacturing country; retain purchase receipts. – If product contains dairy/meat/nuts/seeds/herbs, obtain relevant import permits, veterinary health certificates, or phytosanitary certificates from the supplier or issuing authority before travel. – Translate ingredient list into the destination language when possible and attach an English version for international inspections. – For larger quantities intended for commercial or long-term use, coordinate with destination customs/agriculture agency ahead of shipment to secure permits and avoid confiscation.
