Mold Shipping from China — How Do You Package, Insure and Ship an Injection Mold Overseas, and What Are the Customs and Duty Requirements?
Last updated: 2026-09-03 · Reading time: about 6 min
Shipping an injection mold from China means protecting a 500–5,000 kg precision tool from corrosion, shock and moisture across a 4–8 week journey. Clean and coat it, wrap it in VCI paper, crate it to ISPM-15, insure it for 0.3–0.8% of value, and clear customs under HS code 8480.71.

Cavity — The hollow space inside the mold that forms the part shape. Multi-cavity molds produce multiple parts per shot. Cavity count determines production output but also mold cost and complexity. Each cavity must be balanced for uniform fill. See also related guide.
How do you package the mold for overseas shipping?
Four layers of protection stand between a precision tool and 4–8 weeks of salt air, handling and stacking.
- Clean and protect the cavity surfaces. Remove all residue, grease and moisture, then coat the steel with a rust preventive that will not contaminate the first shots. Blow the cooling channels dry with compressed air — trapped moisture corrodes from the inside.
- Wrap in VCI paper and plastic film. Vapor Corrosion Inhibitor paper releases a protective vapor over the steel; sealed under plastic film it guards the mold for up to 2 years and keeps out moisture and dust.
- Secure it in a wooden crate. Use heat-treated, ISPM-15-compliant plywood, bolt the mold base to the crate and pad it with foam or rubber shock absorbers. Label the weight, center of gravity, lifting points, “fragile” and “do not stack.”
- Pack the documentation and spares. In a waterproof envelope: 2D and 3D drawings, the maintenance manual, the spare-parts list, the T1 sample report, the CMM report and the trial video. Pack wear inserts, ejector pins, springs and O-rings separately.
What are the shipping options — and how do you choose?
Four modes trade transit time against cost per kilogram. Weight and urgency make the call.
| Method | Transit | Cost/kg | When to use |
|---|---|---|---|
| Sea freight (FCL) | 25–40 days | $0.50–1.50 | Large molds (>1,000 kg), non-urgent |
| Sea freight (LCL) | 30–45 days | $1.00–2.50 | Small molds (<1,000 kg), non-urgent |
| Air freight | 5–10 days | $4.00–8.00 | Urgent, small molds (<500 kg) |
| Express (DHL/FedEx) | 3–7 days | $6.00–12.00 | Spare parts, documents, very urgent |
Sea freight is the default. FCL (a full 20 ft or 40 ft container) runs $1,000–3,000 China-to-US-West or $1,500–4,000 China-to-Europe in 25–40 days. Air costs 5–10× more but is 5–8× faster — justified only for an urgent mold or one under 500 kg. Express is for spares and documents, not the tool.
“We treat the crate as part of the deliverable. The mold ships cleaned, coated, VCI-wrapped and bolted into an ISPM-15 crate, with the drawings, CMM report and trial video in a waterproof envelope and the spares packed beside it — so what arrives on your dock is ready to run, not ready to be de-rusted.”

Frequently asked questions
What customs documents are required — and what are the duty rates?
Five documents: a commercial invoice (value, HS code, origin), a packing list (crate dimensions, weight, contents), a bill of lading, a certificate of origin where a trade agreement needs it, and a fumigation certificate proving ISPM-15 treatment of the crate.
Injection molds classify under HS 8480.71. Duty is 0–6% (US), 0–2.7% (EU/UK) and 0–5% (Canada/Mexico), on the CIF value — a $50,000 mold with $2,000 freight at 6% is $3,120. A broker clears it for $100–300.
Should you insure the mold — and what does it cover?
Yes. Insurance runs 0.3–0.8% of the mold value ($150–400 on a $50,000 tool) and covers physical damage, total loss at sea, theft and water damage.
It does not cover corrosion from poor pre-shipment protection, manufacturing defects or delay. A claim needs photos, the shipping documents and a surveyor’s report, and settles in 30–60 days — buy it through the forwarder or a marine insurer.
What are the common shipping problems — and how do you prevent them?
Corrosion (clean, coat, VCI-wrap, seal), handling damage (sturdy crate, foam, shock absorbers, fragile labels) and moisture (desiccant bags, plastic seal, a ventilated container) cover most physical risks.
The rest are paperwork and transit: documentation errors (use an experienced forwarder and verify before sailing) and lost or delayed shipments (reputable carrier, online tracking, insurance). Problems hit fewer than 2% of shipments, but a damaged or late mold stalls the whole production schedule.
Key takeaways
- Package in layers — clean and coat, VCI paper under plastic film, and an ISPM-15 wooden crate bolted down and shock-padded.
- Ship by sea (25–40 days, $0.50–1.50/kg) for most molds, air only for urgent or sub-500 kg tools; clear customs under HS 8480.71 at 0–6% duty.
- Insure for 0.3–0.8% of value; total landed shipping runs 3–8% of the mold cost.
Mold shipping from China is a well-established process — the discipline is in the packaging, the forwarder and the insurance. The freight is a small slice of the mold cost, but corrosion, damage or delay can stall production. Coordinate with your mold maker: they handle the export documents, the forwarder handles import customs and inland transport, and most can arrange the whole leg as part of delivery.
