Shipping Gel Polish from China: Air, Sea and What Counts as Dangerous Goods
Whether your gel is regulated for transport depends on one number in Section 14 of the SDS. What changes when it is Class 3, and why the glass usually costs more to ship than the gel.
Short answer: most UV/LED gels are not regulated for transport, but any product with a flash point at or below 60 °C is a Class 3 flammable liquid, and that changes the paperwork, the packaging and the price. The authority is Section 14 of the SDS, not the sales rep, and not the forwarder's first answer.
How a gel polish gets classified
Classification for transport starts with flash point, measured closed cup. At or below 60 °C the product is a flammable liquid and is assigned a UN number — commonly UN 1263 for paint-related material or UN 1993 for flammable liquid, not otherwise specified — plus a packing group that reflects how easily it ignites. Above 60 °C it is generally not regulated as dangerous goods, which is the case for many HEMA-based UV gels and water-borne formulas. The word "generally" matters: a supplier can change one solvent and move the product across the line.
What changes when it is Class 3
| Mode | Extra requirement | Effect on cost and timing |
|---|---|---|
| Air freight | Dangerous goods declaration, UN-spec packaging, trained shipper, sometimes limited-quantity rules | Higher rate, longer booking lead time, some forwarders decline small shipments |
| Sea freight | IMDG declaration, container stowage rules, dangerous goods surcharge | Surcharge per container, but the cheapest route per kilogram |
| Courier / express | Most carriers refuse Class 3 liquids; limited quantity only, if accepted at all | Samples may have to travel as sea freight or be reformulated for air |
| Non-regulated goods | Ordinary commercial invoice and packing list | Normal rates, normal transit times |
What Section 14 of the SDS must show
- UN number and proper shipping name, or an explicit statement that the product is not regulated.
- Transport hazard class and packing group where applicable.
- Environmental hazards, including marine pollutant status for sea freight.
- Special precautions the handler needs to take.
- The revision date of the SDS — a document without one is not usable for booking.
The freight maths buyers forget
A 15 ml gel weighs roughly 15 g; the glass bottle, brush cap and carton around it weigh several times that. Freight is charged on the greater of actual and volumetric weight, so a light, bulky carton is billed on volume. That is why the shipping cost per bottle barely moves when you switch from 10 ml to 15 ml, and why bottle choice — glass versus PET, thick versus thin — affects landed cost more than the gel inside. Ask for the carton dimensions and gross weight on the quotation, not just the unit price.
Who books the shipment, and under which term
Dangerous goods shipments are rarely offered DDP, because the seller would carry customs and carrier risk in a category most forwarders treat carefully. FOB or CFR is the practical structure: you control the forwarder, you see the surcharges, and you can choose a carrier that actually accepts the class. If a supplier quotes DDP on a flammable product at a surprisingly low price, ask which route and which declaration they are using — the answer is often "we did not declare it", which becomes your problem at the destination.
Documents that must travel with the goods
- Commercial invoice and packing list with gross and net weight per carton.
- Bill of lading or air waybill, consignee exactly as your broker has it on file.
- The SDS, with Section 14 matching what the forwarder was told.
- Dangerous goods declaration where the class requires it, signed by a trained shipper.
- Certificate of origin if your market applies preferential duty.
- Insurance certificate if the term is CIF or CIP.

Five questions before you book
- What is the flash point, and which section of which SDS revision states it?
- Is the product offered as limited quantity, and does that limit how much can travel per carton?
- Which forwarder has actually carried this class for you before, with a reference shipment?
- What are the carton dimensions and gross weight, so I can price volumetric weight myself?
- If the shipment is stopped for an undeclared dangerous good, who pays the storage and the re-export?
