Single-Use Data Loggers for Air & Export Shipments
A one-way international shipment of pharmaceuticals or medical cannabis doesn't need a device you have to track down and retrieve at the destination. This page covers what actually drives the single-use decision, the air-freight battery rule most shippers get wrong, and how DeeMED's single-use FRIGGA devices are built around both.

Why single-use for a one-way export leg
A reusable device only pays off if you get it back. On a one-way export leg, that means paying to ship the logger back to Thailand, or writing it off if the destination party never returns it, either way adding cost and delay a single-use device avoids entirely. It also matches how chain-of-custody actually works on an export shipment: WHO's Technical Report Series 961, Annex 9, treats temperature-controlled transport by road and air as its own distinct segment with its own documentation obligation, ending at the point the product is handed to the receiving party. A single-use logger's data record closes out cleanly at exactly that point; a reusable device instead re-enters someone else's custody chain, which is a harder thing to account for on an audit.
The battery rule that actually matters for air freight
"No dangerous goods paperwork" sounds like a marketing line, but it refers to a real, specific exemption. IATA's Dangerous Goods Regulations, Section 1.2.7.1(i), exempt a lithium-battery-powered tracking device or data logger from full Dangerous Goods Declaration requirements only if it meets a defined set of criteria: the battery must pass UN38.3 test certification, stay within capacity limits (20 Wh or less for lithium-ion, 1 gram or less for lithium-metal), the device must be designed to prevent any dangerous release of heat, and it must meet prescribed electromagnetic interference standards for aircraft avionics, among other conditions. A logger that doesn't clear all of these still ships as regulated dangerous goods, with the paperwork, packaging, and handling delays that come with that classification. DeeMED's single-use devices are built to run on non-lithium battery chemistry with Auto Flight-Mode instead, sidestepping the exemption criteria altogether rather than needing to qualify under them shipment by shipment.
What happens when a shipment shows an excursion
A single-use logger's real job starts when something goes wrong, not when everything goes right. Under EU GDP guidelines (2013/C 343/01), a temperature excursion recorded in transit doesn't automatically mean the product is unusable, it means the receiving Qualified Person has to make a documented decision on whether the product remains fit for release, based on the excursion's duration, severity, and the product's own stability data. That decision is frequently grounded in Mean Kinetic Temperature, a single derived figure defined in ICH Q1A(R2) that expresses the total thermal stress a product experienced over the shipment as one weighted value, rather than a simple high-low range. A brief spike outside range doesn't automatically fail a shipment under this math if the product's overall thermal burden across the full trip still falls within its approved stability limits, provided its degradation follows known kinetics, which is exactly why a complete time-temperature record from the logger, not just a pass/fail alert, is what a QP actually needs to make that call. A real-time cellular device with live SMS and email alerts lets a receiving party (or DeeMED, monitoring in transit) catch and respond to an excursion while the shipment is still moving, rather than discovering it after the fact from a passive log pulled at delivery. For lower-risk cargo where that live response isn't necessary, a passive USB logger that simply records the full time-temperature history for review at destination is enough to support the same QP release decision, at a lower cost per unit.
Single-use vs. reusable: how to decide
The right device type comes down to one question: does the logger come back to you? If a shipment is a one-way international leg, whether that's a pharmaceutical export, a medical cannabis shipment, or a single high-value air freight run, a single-use device scopes the cost to that one shipment and closes out its chain-of-custody cleanly at delivery. If a route repeats, domestic or regional, a reusable device is almost always the better economics, which is what our reusable data loggers page covers in full.
| Shipment pattern | Retrieval | Best fit |
|---|---|---|
| One-way international air or sea export | Destination party rarely returns it | Single-use |
| High-value pharma or medical cannabis export | Chain-of-custody ends at delivery | Single-use |
| Lower-value or lower-risk export cargo | Cost-per-unit matters more than live alerts | Single-use (USB) |
| Domestic distribution run, repeats weekly | Device returns to base every trip | Reusable |
| Reefer-truck lane, fixed route | Device stays with the vehicle | Reusable |
| Mixed fleet, some legs domestic, some export | Varies by leg | Both, by leg |
DeeMED's single-use FRIGGA devices
DeeMED is the official Thai distributor for FRIGGA and sells these single-use devices directly, we don't rent or lease them. The V5-C-Core is our flagship single-use device for pharma and medical cannabis export, tracking temperature, humidity, light, tilt, location, motion, and shock in real time over 2G/4G/5G/WiFi, with instant SMS and email alerts on an excursion, running on non-lithium battery chemistry with Auto Flight-Mode so it clears air freight without a Dangerous Goods Declaration. The U1 is a compact, economy single-use USB logger for straightforward temperature-only tracking, plugging directly into a USB port at destination for an instant PDF report with no cloud account required, the right fit for lower-value or lower-risk cargo where a full real-time device isn't justified. Both report through Frigga Cloud 2.0, our GxP-validated, US FDA 21 CFR Part 11-compliant monitoring platform, with two years of searchable cloud data retention, so the shipment record is available for a regulator or receiving Qualified Person's audit long after the device itself has been discarded.
