EXPORT FROM SHENZHEN
One accountable handover from production line to carrier
Finished goods pass final AQL inspection in our factory, move through export packing and documentation, and are booked with the carrier under the Incoterm on your proforma. You can use our forwarder, your nominated forwarder, or a split arrangement — your cargo, your choice; the documents and compliance obligations never change.
4Incoterms offered — EXW, FOB, CIF, DDP
25–40 daystypical sea transit to US & EU main ports
5–10 daysair freight door to door
3–7 daysDHL / FedEx courier for samples
Production lead time and freight lead time are separate: factory production runs 15–40 days depending on program tier, as detailed on the lead times page, and the transit bands below start only after goods are packed, documented and released against the agreed payment terms.
INCOTERMS
Who does what under EXW, FOB, CIF and DDP
Obligations split at defined points. The table states the practical allocation brands actually care about — export clearance, main carriage, insurance and import clearance.
| Obligation | EXW (Ex Works) | FOB Shenzhen | CIF (named port) | DDP (named place) |
|---|---|---|---|---|
| Export packing & documents | Seller | Seller | Seller | Seller |
| China export clearance | Buyer (via forwarder) | Seller | Seller | Seller |
| Inland haulage to Yantian/Shekou | Buyer | Seller | Seller | Seller |
| Main ocean/air carriage | Buyer | Buyer | Seller (prepaid) | Seller (prepaid) |
| Freight insurance | Buyer | Buyer | Seller (minimum cover) | Seller |
| Destination port charges | Buyer | Buyer | Buyer | Seller |
| Import clearance, duty & VAT | Buyer | Buyer | Buyer | Seller |
| Typical fit | Experienced importer, own forwarder | Most common standard for B2B programs | Buyer wants prepaid ocean freight | Hands-off landed delivery incl. FBA |
Terms are confirmed on each proforma invoice. DDP is quoted destination-specific and requires importer-of-record arrangements to be agreed in writing.
FREIGHT MODES
Sea, air or express: cost, speed and best use
The smart economy is rarely one mode: launch quantities fly, the base volume sails, and replenishment uses whichever lane still fits the stock-out date.

Transit ranges exclude customs inspections, which destination authorities may add without notice. We book with named sailing or flight details and share the bill of lading or air waybill as soon as it issues, so your receiving team plans against real dates instead of estimates.
LITHIUM-BATTERY COMPLIANCE
Built-in Li-Po cells are fully documented, not smuggled
Smart glasses ship with lithium-polymer cells installed in equipment. The cells used in our platforms come with UN38.3 test summaries (the UN standard transport tests), MSDS safety data sheets and, where the carrier requires, a suitable-packing declaration. Cargo moves under the applicable IATA/IMDG lithium-battery packing instructions.
In everyday terms: batteries packed with or in equipment are handled under the PI966 (with equipment) / PI967 (contained in equipment) family of instructions, with watt-hour limits, state-of-charge limits (typically not charged above 30% for certain cargo modes), UN-marked packaging and the lithium-battery mark and label on the carton. Our logistics team selects the correct provision per lane — passenger-aircraft restrictions and all-cargo rules differ, and sea shipments follow the IMDG Code rather than IATA.
If your nominated forwarder requests additional paperwork — for example a carrier-specific battery declaration or a pre-audit — we supply it in English within one to two working days.
DOCUMENT SET
What travels with every export shipment
A complete document set prevents the two costly warehouse moments: a container stuck at customs, or an FBA appointment refused on arrival.
02
Packing list
Carton count, net and gross weights, carton dimensions, CBM and unit quantities per SKU/color, matched exactly to the invoice.
03
Certificate of origin
General CO available on request; preferential certificates (for example GSP/form types where applicable) assessed per destination before shipment.
04
Bill of lading / AWB
Ocean B/L (telex release or original set) for sea freight, air waybill for air freight — released per the payment milestone.
05
Battery documents
UN38.3 test summary, MSDS and the packing/declaration paperwork matching the actual cells and packing instruction.
06
Compliance dossier
CE/FCC/RoHS/REACH declarations and test reports in your brand name, plus product manuals for the destination market.
AMAZON FBA PREP
Cartons that pass the receiving dock first time
FBA and major-retail DCs enforce labeling and carton rules mechanically — shipments fail on paperwork, not product. We prep against the current seller-central requirements you provide for each shipment.
Carton & pallet prep
FBA labels and carton specs
FNSKU labels applied per unit, shipment-ID carton labels placed clear of seams, carton weight and dimensions within FBA limits, and "team lift"/"mechanical lift" labels where required.
Palletization
Palletized, stretch-wrapped, staged
Heat-treated pallets where the destination requires, standard heights for container loading, stretch wrap and packing photographs shared before booking the delivery appointment.
E-commerce ready
Retail box + polybag
Units in sealed retail polybags where required, with warning suffocation text sized per market; bundling and multi-pack configurations handled against your ASIN setup.
PORTS & TRANSIT
Yantian and Shekou: two gateways, one cluster
Goods normally exit via Yantian International Container Terminals, the deep-water port serving eastern Shenzhen and the PRD manufacturing belt, or Shekou to the west — the choice follows your carrier’s sailing and destination port. Air cargo moves through Shenzhen Bao’an or, for denser flight schedules, Hong Kong or Guangzhou Baiyun; couriers collect directly from our warehouse.
Inland haulage, port entry and terminal handling sit inside FOB Shenzhen pricing. Drayage windows are booked against production completion so goods do not wait in a port warehouse accruing storage.

INSURANCE & RISK
When risk transfers, and how to stay covered
Risk transfers at the point each Incoterm defines — on delivery to the first carrier under FOB, alongside the seller’s minimum cover under CIF, and at your named destination only under DDP. Because minimum CIF cover is capped, most brand customers take out their own all-risk cargo policy for the full commercial invoice value plus freight; we declare values accurately so claims are not underinsured.
Report any carton or pallet damage on the carrier’s delivery receipt at handover — photographic, timestamped evidence at receiving is the basis for every valid freight claim, and our packing photographs document the condition at origin.
HANDOVER CHECKLIST
Before the container leaves: the release sequence
- Final AQL inspection report accepted and balance payment confirmed per the proforma.
- Golden-sample conformance photos of the actual shipment lot shared with your team.
- Carton marks, HS code and commercial-invoice details approved in writing.
- Battery documents and compliance files issued to the forwarder before cut-off.
- Sailing/flight schedule, ETA and document-release method (telex or original B/L) confirmed.
- For DDP/FBA: importer-of-record details, delivery address and appointment window locked.
The same PM who ran production owns the shipment handover, so logistics questions reach someone who knows the carton contents personally.
SHIPPING FAQ
Freight and documentation questions from buyers
Which Incoterm do you recommend for a first order?
FOB Shenzhen is the standard starting point: we handle export clearance and delivery over the ship’s rail (or to the carrier at the named terminal for air), while your forwarder controls ocean freight and destination charges at transparent rates. Customers with mature import teams often use EXW; brands that want a single landed price to their warehouse or FBA use DDP, which we quote per destination.
Can you ship DDP straight to Amazon FBA?
Yes. Under DDP we arrange carriage, import clearance and duty delivery to the named fulfillment center, with FNSKU and carton labeling completed in our warehouse. The importer-of-record arrangement and tax registration details must be agreed before the proforma is issued, and FBA appointment acceptance is subject to Amazon’s receiving rules rather than carrier performance.
How are the built-in lithium batteries allowed on aircraft?
Smart glasses contain small lithium-polymer cells installed in equipment. Shipments are supported by UN38.3 test summaries and MSDS, packed and labeled under the applicable lithium-battery packing instructions (the PI966/PI967 family), and booked on carrier services that accept regulated lithium cargo. Samples ship the same documented way via DHL or FedEx — we never misrepresent battery cargo.
What transit time should I plan for?
Plan 25–40 days for FCL sea freight to major North American and European ports, 30–45 days for LCL including consolidation, 5–10 working days for air freight, and 3–7 working days for express courier — plus destination customs clearance, which varies by country and season. Booking cut-offs before Chinese public holidays and Q4 peak season should add buffer; the lead times page has the production-side schedule.
Do you provide a certificate of origin?
Yes, a general certificate of origin is available with the document set on request. Preferential certificates depend on destination and current trade rules and are assessed before shipment; the commercial invoice always states the country of origin as China. Tell us at PO stage which documents your bank, distributor or retailer requires so nothing is chased after sailing.
Who pays freight insurance?
Under EXW and FOB the buyer arranges and pays insurance; under CIF we take out minimum ocean cargo cover as the term requires; under DDP freight is covered as part of the delivered service. Minimum CIF cover is below commercial invoice value in many programs, so we recommend an independent all-risk policy and provide accurate values for it.
Can we use our own freight forwarder?
Absolutely. Under EXW or FOB most customers nominate their own forwarder; we cooperate on booking confirmation, document handover, battery paperwork and warehouse cut-off times. Split arrangements — our forwarder for a DDP first lot, yours for FCL replenishment — are common and can be changed per shipment without affecting the commercial program.
