The short answer
Use express courier for samples, air freight for urgent or small restocks, and sea freight for volume. As typical reference ranges only: express runs about 3-7 days door to door, air freight about 5-10 days, sea freight to the US West Coast about 15-25 days port to port, and sea freight to Europe about 30-45 days. Door-to-door sea times are longer because they add inland haulage, customs clearance and delivery. Every figure here is a planning range, not a promise; the real schedule is confirmed in writing for each shipment, and it moves with carrier schedules, seasons and customs queues.
Where dash cams ship from
Most dash cams for export are assembled in the Shenzhen electronics cluster, so cargo usually leaves through Shenzhen. Sea freight goes out of the Yantian and Shekou ports, and air cargo leaves through Shenzhen Bao'an or nearby Hong Kong. Because partner factories sit within the same region, a Roadtrace order is typically consolidated in Shenzhen after pre-shipment checks and then handed to the forwarder. If a program mixes products from more than one partner factory, consolidation adds a few days before the cargo is ready to move; ask for that step to be shown on the schedule rather than discovered later.
The four modes compared
| Mode | Typical transit | Best for | Watch out for |
|---|---|---|---|
| Express courier | About 3-7 days door to door | Samples, a few units, urgent replacements | Per-kilogram cost rises quickly with volume; remote addresses add days |
| Air freight | About 5-10 days | Small restocks, launch stock, seasonal top-ups | Lithium battery models need extra documents; chargeable weight counts packaging volume |
| Sea freight, US West Coast | About 15-25 days port to port | Regular volume with planned stock | Door-to-door is longer; port congestion and inland haulage vary |
| Sea freight, Europe | About 30-45 days | Planned bulk replenishment | Longest cash cycle; plan reorders early |
Express is the right tool while you validate a model. Once you move to bulk, the question becomes how many weeks of stock you are willing to hold, which the inventory planning note works through.
Choosing a mode by order stage
- Sample stage: send by express. You need the unit in hand quickly, and the quantity is too small for any other mode to make sense. The MOQ and lead time page lists typical sample timing.
- Trial order: a first run of a few hundred units often goes by air or by sea in a shared container, depending on how long you can wait. Trial orders are where you learn your real label, carton and customs workflow.
- Regular replenishment: sea freight, with air held in reserve for stock-outs. Sellers who rely on air for everything usually have a cash-flow or planning problem, not a logistics problem.
- Peak preparation: book sea freight early enough to land before the promotion window, and keep a small air allocation for corrections.
Packing for the journey
A dash cam reaches the buyer as a retail gift box inside a master carton, with carton marks set by the buyer. Good packing is dull and consistent: each gift box carries the model and any barcode label you specified, each master carton carries a content label, carton count and weight, and a packing list matches what is actually inside. If you sell through a marketplace, warehouse labeling such as FNSKU-style barcodes can be applied before shipment on request, which saves handling at the receiving end. The marketplace preparation note covers label placement in detail.
Check the carton specification before the order is booked: dimensions, units per carton, gross weight. Those numbers decide whether a pallet or container is full, and chargeable weight in air freight depends on volume as well as mass.
Documents and customs basics
A normal export set contains the commercial invoice, packing list and the transport document issued by the forwarder or carrier. For import, your customs broker will also need the product description, the quantity, the declared value and the classification. Dash cams are commonly classified under HS heading 8525 (cameras), but the exact code for your product is a question for a licensed customs broker; the HS code note shows how to prepare for that conversation. Duty and tax depend on your destination country and are not stated here.
Models with a lithium battery need a UN38.3 test summary and a safety data sheet for air and sea transport, and some carriers add restrictions. Supercapacitor models avoid most of that paperwork, which is one more reason fleet and reseller programs favor them.
Who carries which part of the journey
How far the seller takes the cargo depends on the trade term you choose: from the factory gate, to the port in Shenzhen, to your port, or to your door. The Incoterms note explains the common terms; the practical point here is that the term decides who books the forwarder, who pays for each leg, and who bears the risk if a container is delayed or damaged.
Delays and how to reduce them
- Ready date slips: usually from late artwork, a changed label or a rework after pre-shipment inspection. Freeze packaging files before production starts.
- Booking misses: when space is tight, sailings fill up. Share the expected ready date early so the forwarder can hold space.
- Customs questions: a vague product description invites queries. Use a plain function-based description agreed with your broker.
- Port and weather events: unavoidable, so keep a buffer in your reorder point rather than in your hopes.
Ask for tracking at each hand-off: ready date, cargo handed to the forwarder, departure, arrival and release. Five dates are enough to see where a delay began.
What to confirm before you book
For each shipment, get these in writing: mode and route, trade term, ready date, carton specification, label requirements, document list and the responsible party for each leg. The logistics and shipping page sets out how Roadtrace coordinates these steps, and the quote form is the fastest way to start a shipment brief with your destination and volume.
