CBSA extends SIMA duties on Chinese solar modules: what importers need to know

The CBSA just wrapped an expiry review on photovoltaic modules and laminates from China and decided to keep the anti-dumping and countervailing duties in place. If you’re importing solar equipment, this isn’t new news. These measures have been running since 2015, but the expiry review outcome locks in your duty exposure for another five years.

What the expiry review actually decided

Under SIMA paragraph 76.03(7)(a), the CBSA has to decide: if we lift these duties, would Chinese exporters go back to dumping? The agency said yes, so the measures continue. The full determination is published, and the practical takeaway is that your landed cost math on Chinese-origin PV modules doesn’t change.

These duties cover crystalline silicon photovoltaic modules and laminates, whether framed or unframed. If it’s a module or laminate with cells, and it came from China, it’s subject goods. The dumping margins and subsidy rates vary by exporter. Some are at the general rate, some have specific rates from prior reviews.

Why this matters for your import program

If you’ve been importing solar modules from China, you already know the drill: the normal customs duty, plus the SIMA dumping duty, plus the countervailing duty (if applicable), plus GST on the aggregate. The math gets heavy fast, especially on commercial-scale shipments.

The expiry review keeps that structure in place. You don’t get a sudden duty holiday, but you also don’t face new uncertainty. The rates you’ve been paying are the rates you’ll keep paying.

For importers who haven’t touched Chinese solar yet, this is the baseline cost reality. You’re not buying modules at invoice price. You’re buying them at invoice plus SIMA duties plus regular tariff. Run the full landed cost before you commit to a supply agreement.

Sourcing alternatives under CUSMA and other FTAs

One reason importers ask about SIMA goods is to figure out whether sourcing from a different origin makes sense. For solar modules, that’s a real calculation.

If you source from a CUSMA partner (U.S. or Mexico), you can claim preferential duty treatment: zero MFN tariff and no SIMA exposure, assuming the goods meet CUSMA rules of origin. But you need to verify that the modules aren’t just trans-shipped Chinese product. CUSMA origin requires substantial transformation in the territory of a CUSMA country. Assembly of Chinese cells in Mexico doesn’t automatically qualify.

CETA (Canada-EU) is another option if you’re sourcing from European manufacturers. Same principle: zero MFN duty if the goods originate in the EU, and no SIMA exposure because the measures are specific to China.

The trap: assuming that any non-China invoice gets you out of SIMA. Origin isn’t where the invoice is issued — it’s where the goods were made. If a U.S. distributor sells you modules that were manufactured in China, they’re still subject goods. You’ll face SIMA duties, and if you mis-declared the origin to avoid them, you’re looking at AMPS penalties.

We verify origin claims before filing the CAD. If the commercial invoice says “Made in China” and the supplier can’t produce a certificate of origin from a qualifying FTA country, the goods are Chinese. File accordingly.

What to do if you’re already importing under these measures

If you’ve been importing Chinese solar modules under SIMA, nothing changes operationally. Keep doing what you’ve been doing: declare the goods accurately, pay the duties, and keep your paper trail clean.

One thing to watch: if your supplier changes their exporter of record, the SIMA rate might change. Different Chinese exporters have different dumping margins. If your supplier switches from one factory to another, check the CBSA’s list of applicable rates for that exporter. You might move from a company-specific rate to the general rate, or vice versa.

Also, if you’ve been paying duties under protest or you had a pending appeal on a prior SIMA determination, the expiry review outcome might affect your case. That’s a conversation for your compliance team. The review decision can sometimes be used as supporting evidence in retroactive duty disputes.

What an expiry review actually is

In case you haven’t dealt with one before: SIMA duties don’t run forever on automatic renewal. Every five years (give or take), the CBSA has to conduct an expiry review to decide whether the measures should continue or be rescinded.

The test is: if we remove the duties, is there a likelihood that dumping (or subsidization) would resume and cause material injury to the Canadian industry? If yes, the duties continue. If no, they expire.

In this case, the CBSA said yes. Continuation is warranted. That means the duties stay in force for another defined period, and Canadian solar importers continue to face the same duty structure they’ve been navigating since 2015.

For the Canadian solar module manufacturing industry, this is a win. For importers sourcing from China, it’s a known cost that’s now locked in for another cycle.

If your duty math doesn’t add up

We see importers who’ve been paying SIMA duties for years without ever verifying whether their classification is correct, or whether they qualify for an exclusion, or whether their supplier’s exporter code is the right one.

If your landed cost on Chinese solar modules feels wrong, or if your broker has been filing at the general SIMA rate when your supplier might qualify for a lower company-specific rate, that’s fixable. We pull the CBSA determination docs, cross-check the exporter of record, and re-run the duty calculation.

Most of the time, the rate is correct and the cost is just what it is. But once in a while, we find a mismatch: wrong HS code, wrong exporter, wrong rate applied. On a container of modules, that’s real money.
