The laboratory does not mind who carries the box. It cares what the box says, what the customs declaration says, and whether the configuration inside matches the test plan.
Most projects answer this question by accident. The factory built the samples, the factory has a courier account, so the factory ships the box and emails you a tracking number. Nobody asked permission, and the laboratory does not need to give it. Shipping directly from the factory to the lab is normal and often the fastest route.
The problems are not about permission either. They live in three documents that get filled in when the box leaves: the waybill, the customs invoice and the packing list. When the factory ships, those documents are completed by people who have never seen your quote, your test plan or the model numbers your buyer will list the product under. That gap is where delayed projects come from - not from the shipping itself.
A testing laboratory receives dozens of boxes a week from companies its accounting system has never heard of. Intake works by matching every arrival to an open quote or booking. When a box shows up with no project reference on any document, it goes on a shelf while someone guesses which project it belongs to. Meanwhile the bench slot you reserved is held for a machine that has nothing to test, and if the slot expires the project goes back into the queue behind everyone else.
So the first requirement is simple and applies no matter who ships: the waybill and the packing list must carry the project or quote reference, and the contents must match what the test plan describes. Intake checks the model, the quantity, the firmware version and the accessories against the plan before anything is powered on. A box that matches walks straight into the schedule. A box that does not generates questions, and questions cost days.
Test samples cross a border, so they need a customs declaration even though nothing is being sold. Two rules cause almost all of the trouble.
First, couriers and customs authorities require a declared value even for goods supplied free of charge. The standard, honest approach is a commercial or proforma invoice showing the fair value of the goods with a note such as "samples - value declared for customs purposes, no commercial transaction". What factories sometimes do instead is declare a token value to avoid attention. That is a misdeclaration, not a saving. The realistic outcomes are a customs hold, an inspection, brokerage charges and occasionally a penalty - and the shipment loses the days the booking was built around.
Second, somebody has to clear the shipment, and that somebody is usually not the laboratory. Most testing laboratories will not act as the importer of record for client samples: they are not set up to pay duties on shipments that belong to someone else's project. This makes the shipping terms matter more than most people expect.
| Arrangement | Who handles customs charges | What happens in practice |
|---|---|---|
| DAP, consignee named as the laboratory | Consignee is contacted to pay duties and fees | The commonest cause of boxes stuck in customs - the lab is asked to pay for a shipment that is not theirs, and usually refuses until you intervene |
| DDP, sender pays all charges | The factory or you, upfront | The cleanest option. The box moves without anyone at the destination being asked for money |
| Client ships from their own side | You | Full control of the documents, but slower and costlier when the samples are sitting at the factory |
Before anything ships, ask the laboratory two things: exactly which consignee name and address to use, and which reference format they want on the documents. Thirty seconds on the phone prevents the DAP situation, which is the single most common reason a factory-direct shipment sits in a customs warehouse instead of on a bench.
If the samples contain lithium batteries and will fly, the shipment must comply with the IATA Dangerous Goods Regulations for the configuration involved: the correct lithium battery mark on the package, the per-package quantity limits that apply to the configuration, and - since 1 January 2020 - a UN38.3 test summary available for the battery. The UN38.3 transport requirement is its own subject; the point here is narrower. A factory that regularly ships finished goods by air usually has this paperwork routine. A factory that ships a one-off courier box for testing often does not.
When the paperwork is missing, the failure is not a fine at the laboratory. It is the courier refusing the box at pickup, or the airline rejecting it at export, and the whole schedule slips while a freight forwarder is found. If the factory cannot produce the battery documentation, route the shipment through a forwarder who handles dangerous goods instead of hoping the courier does not ask.
While you are at it, check the configuration itself. The samples are not just "a product in a box" - the accessories, cables and adapters shipped with them define the configuration that gets measured, and a missing adapter changes what the report can say about your product.
Laboratories photograph the packaging at intake. This is not bureaucracy; it is the record that settles what happened when a sample arrives damaged. Three units shipped, one arrives crushed - the lab will not quietly test two and write "three" in the report, and it will not substitute a spare from another project. The intake photos and the packing list decide whether the damage happened in transit and what has to happen next: a re-shipment, a rebooked slot, and a courier insurance claim on the sender's side.
Transit damage costs more than the unit. It costs the slot. Protective packaging for a courier journey is not the same as the export carton designed for a pallet, and a factory that ships test samples like it ships orders will eventually send you a photograph of the result.
These are the recurring versions of the same story. None of them involve the testing.
There are situations where the honest answer is "don't ship yet" or "don't let the factory handle this one".
Sample logistics is the last unsupervised step before testing starts, which is why our intake treats it as part of the testing and certification programme rather than a delivery event: arrivals are matched against the booking, packaging is photographed, the configuration is verified against the test plan before the slot starts, and anything that does not match is flagged to you the day the box opens - not the day the project slips.
A factory can ship test samples directly to a testing laboratory, and usually should - it is faster than routing through the client. What decides whether it goes smoothly is the paperwork, not the permission: the waybill and packing list must carry the project reference and the model numbers that will appear in the report; the customs invoice must declare the honest fair value of the goods even though they are supplied free of charge; the shipping terms should be DDP, because most laboratories will not act as importer of record and a DAP box addressed to the lab is the classic recipe for a customs hold; and any configuration containing lithium batteries must fly with the IATA-mandated lithium battery mark, quantity limits and the UN38.3 test summary required since 1 January 2020. Confirm the consignee details with the laboratory, freeze the configuration before the box is packed, and send the tracking number ahead of arrival. Everything else is just a courier.
Shipping samples this week? Send us the waybill details, the packing list and your test plan reference before the box leaves the factory. We will confirm the consignee details, the declared value and the configuration list against your booking, so the samples walk straight into intake instead of sitting in customs or on a receiving shelf.
Yes, and it is the normal route. The laboratory matches arrivals to open bookings, so the waybill and packing list must carry your project or quote reference and the model numbers from the test plan.
Whoever the shipping terms assign them to. Most laboratories will not act as the importer of record for client samples, so DDP - sender pays all charges - is the practical default.
The honest fair value of the goods, with a note that they are samples and no commercial transaction is involved. A token value is a customs misdeclaration and can trigger holds, inspection and penalties.
Yes, if the shipment meets the IATA Dangerous Goods Regulations for the configuration: lithium battery mark, per-package quantity limits, and the UN38.3 test summary required since 1 January 2020. Otherwise use a dangerous goods forwarder.
The laboratory photographs the packaging at intake and checks the configuration against the test plan before starting. Damaged units are not silently replaced; expect a re-shipment and a rebooked slot, with the claim on the sender's insurance.
Return shipping is normally arranged at your cost to any address you specify. Some tests consume the sample, so ask which units survive before booking the return.
