Importing Metal Powder from China

1. Choose the Right Incoterm

The Incoterm decides who pays for transport, who carries risk, and who handles export formalities. For powder purchases the practical set is small:

Rule of thumb: samples via courier on DAP, first commercial lot on FOB, and only move to EXW once you have a forwarder you trust and the volume to justify it.

2. Payment Safety

3. Dangerous-Goods Logistics — Plan Before You Order

Many metal powders are regulated dangerous goods. This affects shipping mode, packaging, and cost far more than most first-time buyers expect:

• Reactive metal powders (titanium, aluminum, magnesium, zirconium and many of their alloys) are typically Class 4 flammable solids — UN packing groups depend on particle size and specific grade. They generally cannot fly as ordinary air cargo and need UN-certified packaging.
• Non-reactive powders (stainless steels, nickel alloys, cobalt-chrome, copper) usually ship as non-DG general cargo, which keeps air freight cheap and simple.
• Passivation: many suppliers ship reactive powders passivated or wet-inerted; confirm the packaging method because it changes your unpacking and sieving procedure.
• Documentation: insist on the SDS (in your language if required by local law), dangerous-goods declaration, certificate of analysis and packing list in the same shipment packet.
• Ocean freight is the standard for volume lots of reactive powder; plan 4-8 weeks of transit plus port clearance.

4. Customs & Tariffs

Metal powders fall under their base-metal HS chapters (e.g. titanium powder, aluminum powder, nickel powder each have dedicated headings). Tariff treatment varies by country and by powder type — spherical atomized powder can classify differently from flake or sintered powder in some jurisdictions. Two practical rules:

• Get the classification in writing before shipping — ask your forwarder or customs broker to confirm the HS code and duty rate for your exact grade and form; a wrong classification discovered at the border costs weeks.
• Check free-trade or preferential rules only if your forwarder confirms eligibility — claiming preferential origin without the certificate of origin leads to duty recovery later.

5. Arrival Inspection — the 5 Checks

1. Seals & packaging: intact UN packaging, no moisture ingress, passivation intact.
2. Documentation match: lot numbers on cans match the certificate of analysis and packing list.
3. Chemistry: retest one sample per lot by ICP-OES against the certificate — independent lab if the value warrants it.
4. PSD & flow: laser-diffraction particle-size distribution and Hall flow within your agreed spec window.
5. Oxygen/nitrogen: for titanium, aluminum and maraging steel especially — confirm the delivery lot meets the certified oxygen level.

Run these checks on the first lot of every new supplier regardless of certificates. It costs a few hundred dollars and prevents six-figure production failures.
