Why smart glasses shipping starts with the battery
A pair of smart glasses carries two small lithium-ion cells in the temples, typically 85-235 mAh in total across the category. That puts every shipment into dangerous goods rules for lithium batteries, even though the cells are tiny. The classification depends on how the battery travels: cells built into the glasses are lithium-ion batteries contained in equipment, UN3481; a charging case with its own cell can be classified differently. The test basis for all of it is the UN 38.3 test summary for the cell or battery, which the partner plant supplies and the desk checks for model, rating and test lab before the first shipment.
The desk plans the shipping route at the spec sheet stage rather than at the end, because the battery rating, the charging case design and the carton count all affect which service can carry the goods.
Air and courier: UN3481 under PI 967 Section II
For air, smart glasses with built-in cells are normally shipped as UN3481 under IATA Packing Instruction 967, Section II, which applies to small batteries contained in equipment. The main conditions, per the IATA 2026 Lithium Battery Guidance Document, are:
- Each cell no more than 20 Wh and each battery no more than 100 Wh - smart glasses cells sit far below both limits.
- On passenger aircraft, no more than 5 kg net weight of lithium-ion batteries per package.
- The lithium battery mark on the package and a battery statement on the air waybill or shipping documents.
- The equipment protected against accidental activation and packed in strong outer packaging.
- A state of charge of 30% or less is recommended for batteries in equipment; under PI 967 it is a recommendation, not a requirement.
Courier and air services typically deliver in 5-10 days. Individual carriers and destinations add their own acceptance rules, so the forwarder confirms acceptance for each lane before booking. The detailed walk-through is in UN 38.3 for smart glasses.
Sea freight: FCL and LCL
For larger batches, sea freight is the usual choice. Programs ship as LCL (consolidated cargo) when the batch fills part of a container and as FCL when it fills a container or when several models are combined. Typical transit times are 15-25 days to the US West Coast and 30-45 days to Europe, port to port, before customs clearance and inland delivery. Sea shipments of equipment with lithium batteries are also declared under the dangerous goods rules for sea transport, and the forwarder confirms what the carrier requires.
| Mode | Typical transit | Suits | Battery handling |
|---|---|---|---|
| Courier and express air | 5-10 days | Samples, golden samples, first restocks | UN3481, PI 967 Section II, mark plus document statement |
| Air freight | 5-10 days | Urgent batches, launch stock | Same, with 5 kg per package on passenger aircraft |
| Sea LCL | 15-25 days US West Coast; 30-45 days Europe | Part-container batches, mixed models | Declared per sea dangerous goods rules via the forwarder |
| Sea FCL | 15-25 days US West Coast; 30-45 days Europe | Full batches and consolidated programs | Same |
Transit times are typical reference ranges and are confirmed in writing for each program.
Charging cases and spare batteries
A charging case that holds its own cell and is packed with the glasses can be classed differently from a case shipped alone. Packed with or inside equipment it is usually handled under UN3481; a powered case or a spare battery shipped on its own may fall under UN3480, lithium-ion batteries on their own, which has stricter air rules. The decision is made per watt-hour rating and per packing configuration, which is why the desk records the case battery rating on the spec sheet and asks the forwarder to confirm the classification before the first booking. Case design is covered on battery and charging and in charging cases for smart glasses.
HS code references for smart glasses
Tariff classification is decided by the importer and its customs broker, not by the supplier. The references below are the headings commonly considered for this category; treat them as a starting point to confirm.
| Product | Heading commonly considered | Note |
|---|---|---|
| Audio glasses | 8518.30 or 8517.62 | Headphone-type audio vs wireless communication apparatus; depends on function and ruling practice |
| Camera glasses | 8525.89 | Cameras with recording function |
| Plain sunglasses | 9004.10 | Without electronics |
| Spare lenses | 9001.40 or 9001.50 | Glass or other material spectacle lenses |
| Accessories | By material and function | Cases, cables and pads classified separately |
All codes are confirmed with your customs broker for the destination market. More detail is in HS codes for smart glasses.
Documents that travel with a shipment
A standard set includes the commercial invoice, packing list, UN 38.3 test summary, battery declaration for the waybill, carton marking photos and, for the destination, the compliance documents your importer needs. Timing for the whole chain is on MOQ and lead time; share the destination and Incoterm through the quote form.
