Exporting Wood Chips to Japan: What's Actually Required

Japan's import rules sort US wood products by one main question: does it still have bark on it?

Bark-free, processed wood moves easily. Lumber and preserved timber without bark, along with veneer, are unrestricted. No phytosanitary certificate needed.

Wood with bark is restricted. Logs with bark require a phytosanitary certificate, and field-chipped wood from whole trees falls in the same category, since the bark goes through the chipper with everything else. Wood pellets also require a certificate.

If you're chipping orchard removals or whole trees in the field, plan on a certificate. There is no wood-chips-specific entry in USDA's database, so certifying officials classify bark-on chips under the closest category, which is logs with bark.

Japan specifically requires the federal certificate (PPQ Form 577), not a state certificate. In most states, your local county agricultural commissioner or state department of agriculture issues federal certificates under a cooperative agreement with USDA, so the inspection still happens locally. The application runs through USDA's PCIT system.

Since August 2023, Japan enforces its certificate requirement strictly. Shipments of plant products arriving without a required certificate are rejected, which means destroyed or shipped back at the exporter's expense.

Japan requires that the official inspection behind the certificate happen no more than 30 days before shipment. That drives your scheduling: the inspection has to be booked against your actual loading and sailing dates, not done weeks ahead whenever it's convenient.

The inspection itself is usually straightforward. The inspector examines the staged chip pile before loading. In our experience, county offices need as little as one working day's notice, and they don't need to be present for the container loading itself. Government costs are modest: in one California county, the certificate runs about $55 plus an hourly inspection charge, with total government cost for a single container typically landing between $200 and $250.

Here's the finding that surprises people. USDA's export database does not require any pre-export treatment for bark-on wood chips to Japan. Certificate plus inspection, that's the US-side requirement. County export desks confirm their wood exporters don't routinely fumigate this class of product.

That doesn't mean fumigation is never involved. Japan inspects arriving cargo, and fresh wood with bark can carry live insects. If pests are found at the port, treatment or destruction happens there, at the consignee's cost. Some Japanese buyers ask for pre-export fumigation as insurance against that risk, and some may require it contractually.

The right order of operations: have your Japanese buyer confirm with their local Plant Protection Station exactly what MAFF will expect for your product, in writing, before anyone books or pays for treatment. If treatment is required or wanted, it needs to be performed by a licensed operator and documented on the certificate. If it's not required, you just saved a line item that fumigation brokers would have been happy to sell you.

A phytosanitary certificate can never be amended upward after it's issued. If you certify 20 tonnes and end up loading 22, you start over, including a new inspection. Always file for the maximum quantity that could ship.

Bark-on wood chips to Japan need a federal phytosanitary certificate, an inspection within 30 days of shipment, and nothing else on the US side unless your buyer's import requirements say otherwise. The certificate and inspection typically cost a few hundred dollars in government fees. The most expensive mistakes are shipping without the certificate, letting the inspection window lapse, and paying for fumigation nobody required.

If you're shipping wood chips, biomass, or any ag product to Japan and want the paperwork handled, that's what we do. We verify your destination's current requirements, prepare and file the application, and coordinate the inspection wherever your goods sit in the lower 48. First shipment is $50 flat, plus government fees at cost.
