China slaps 73.5% preliminary AD duty on Canadian pea starch — what that means if you're the Canadian exporter

The margin

China’s Ministry of Commerce announced a 73.5% preliminary anti-dumping duty on Canadian pea starch imports, effective July 1. The investigation ran ten months, launched last August on the same day Beijing imposed preliminary AD duties on Canadian canola. The ministry’s finding: Canadian pea starch is being dumped, causing material injury to the domestic industry.

If you’re a Canadian exporter shipping pea starch into China, that 73.5% margin lands on top of your FOB price before your Chinese importer even clears customs. A container that used to clear at, say, RMB 120,000 CIF now faces an additional RMB 87,800 in anti-dumping duty alone. Your buyer absorbs that hit unless your sales contract explicitly allocates AD/CVD liability back to you. Most don’t.

The mirror problem

This is the inverse of what we handle daily on the Canadian inbound side under SIMA. When CBSA applies anti-dumping or countervailing duty margins to subject goods arriving in Canada, we file the CAD with the normal value or export price declared separately, calculate the margin, post financial security if the importer doesn’t have an RPP bond that covers SIMA exposure, and track the provisional period until the Canada Border Services Agency or the Canadian International Trade Tribunal issues a final determination.

The mechanics are parallel. China’s Customs applies the margin at entry. If the Chinese importer challenges the classification, normal value, or injury finding, they can request a review or file for exclusion. But the duty applies immediately. Your shipment doesn’t wait for an appeal.

If you’re advising a Canadian exporter, the first question is whether the pea starch in question even falls within the scope of China’s investigation. The ministry’s scope language will specify HS classification, processing degree, and exclusions. Pea protein isolate, for example, may sit outside the investigation even though both derive from yellow peas. Read the scope paragraph in the preliminary determination. If your product is borderline, get a Chinese customs lawyer to draft a scope exclusion request before you ship.

What changed on the Canadian outbound side

Most Canadian exporters don’t carry the same compliance load that importers do. You file an export declaration through the Canadian Export Reporting System if the goods are controlled, strategic, or above the reporting threshold. Pea starch isn’t controlled. You’re not filing a drawback claim. You’re not claiming preferential origin in reverse. The Canadian side of the export is low-touch.

But if your buyer in China now faces a 73.5% duty, one of three things happens. They stop buying. They demand you cut your FOB price by enough to absorb part of the margin. Or they ask you to ship through a third country and provide a certificate of origin showing non-Canadian origin, which is fraud if the goods are still Canadian and you know it.

We’ve seen the third option tried during previous AD investigations. It doesn’t work. China Customs has access to global shipping data, supplier registries, and pea starch production capacity by country. If Canadian yellow pea starch suddenly shows up with a Mongolian or Kazakhstani certificate of origin and no corresponding processing facility exists in that country, the shipment gets flagged, the duty applies retroactively, and the importer faces penalties. The exporter’s reputation with that buyer is done.

Documentation you need now

If you’re still shipping into China post-July 1, your Chinese importer will need clean documentation to support any exclusion or normal-value adjustment claim they file. That means:

• Commercial invoice with HS classification at the 10-digit China Customs level, not just the 6-digit international code.
• Packing list with lot numbers, processing dates, and country of origin clearly stated.
• Certificate of origin (non-preferential) issued by a Canadian chamber of commerce, showing Canada as origin country. Don’t try to obscure it.
• Processing flowchart or technical spec sheet if the product sits near the edge of the investigation scope. If your pea starch is chemically modified, enzyme-treated, or blended, that may matter.
• Sales contract showing FOB or CIF terms and whether AD/CVD liability is allocated. If your contract is silent, Chinese law typically assigns the duty to the importer of record, but that’s cold comfort if they stop buying.

Your freight forwarder on the Canadian export side won’t catch most of this. They’ll move the container, file the AES record if required, and hand you a bill of lading. The compliance burden sits with the Chinese importer, but if you want to keep that customer, you provide the documentation that lets them argue for exclusion or a lower margin.

The CUSMA angle that doesn’t help

Some Canadian exporters assume CUSMA, CETA, or CPTPP protections extend to third countries. They don’t. China is not a party to CUSMA. There is no Canada-China preferential trade agreement that would shield your exports from anti-dumping duties. The WTO allows members to impose AD duties as long as the investigation follows WTO Anti-Dumping Agreement procedures. China’s investigation ran ten months, included provisional measures, and will be followed by a final determination. That’s compliant with WTO rules, even if the margin is punitive.

If you’re exporting under a different FTA to a different destination and your buyer re-exports to China, the trans-shipment doesn’t change the origin. Canadian pea starch is Canadian, regardless of how many borders it crosses. Origin is determined by the country where the last substantial transformation occurred. If you’re milling yellow peas in Saskatchewan and producing pea starch, the origin is Canada. Period.

What Canadian importers should watch

If you’re a Canadian importer bringing in pea starch from China, this doesn’t directly affect you unless China retaliates further or restricts exports to Canada. The trade friction that triggered this started with Canada’s tariffs on Chinese EV imports last year, followed by China’s canola duties, and now pea starch. If you’re importing Chinese goods in a category that Canada has flagged for trade remedy action, expect mirror investigations.

We track SIMA notices and preliminary determinations daily through the CBSA SIMA registry. If your HS line shows up, you have about fourteen days to review your RPP bond coverage, confirm your financial security is sufficient to cover provisional duties, and decide whether to front-load shipments before the margin applies. On the compliance side, that’s routine. On the export side, Canadian sellers are learning the same lesson in reverse.

One of our exporters asked last week whether they should reclassify pea starch as something else to avoid the duty. The answer is no. Reclassification to evade an anti-dumping order is fraud. If the product is pea starch, it’s pea starch. Declare it correctly, provide the documentation, and let the Chinese importer decide whether to fight the margin or walk.
