Section 301 Tariffs Canada 2026: How US Tariffs on Chinese Goods Affect Canadian Importers

A Canadian electronics importer buying $100,000 of consumer drones from Shenzhen via a Texas distributor pays the US distributor's invoice price (which already includes US Section 301 tariffs of 25%), plus Canadian MFN duty, plus any Canadian retaliatory surtax, plus 5% GST. That same shipment direct from China to Vancouver skips Section 301 entirely.

Section 301 is a US-only law, but it cascades into Canadian landed cost through US distributor pricing. Most Canadian importers don't notice — and overpay 15-30% on Chinese-origin goods routed through US suppliers as a result.

What Section 301 actually is

Section 301 of the US Trade Act of 1974 (19 USC § 2411) authorizes the US Trade Representative to retaliate against foreign trade practices it deems unfair. The current China-focused investigation 301-2018 produced four "lists" of Chinese imports subject to additional duties:

• List 1 (~$34B of Chinese imports): 25% — industrial inputs, electronics
• List 2 (~$16B): 25% — chemicals, machinery
• List 3 (~$200B): 25% — broad consumer and industrial goods
• List 4A (~$120B): 7.5% — consumer goods (List 4B suspended)
• 2024 USTR review increases: EVs raised to 100%, lithium-ion batteries 25%, solar cells 50%, semiconductors 50%, syringes/PPE 50%

Section 301 applies only to imports INTO the United States. It does NOT directly tax goods imported into Canada, even when those goods are Chinese-origin. A Canadian importer bringing a container of Chinese consumer goods directly to Vancouver via a Pacific carrier never pays Section 301.

Why it shows up in your Canadian landed cost anyway

Three indirect mechanisms.

### 1. Buying via US distributors

The most common case. A US distributor imports Chinese goods, pays Section 301 at the US border, marks up the merchandise, and resells to Canadian customers. The Section 301 tariff is bundled into the unit price.

Example: an Ontario contractor needs 1,000 LED light fixtures from a Shenzhen manufacturer. Two options:

• Direct from China to Canada: $50/unit FOB Shenzhen + $5,000 ocean freight + Canadian duty (0% MFN for HS 9405) + 5% GST = roughly $73,500 CAD landed.
• Via US distributor: same fixtures at $50/unit FOB China to the distributor + ~$40 distributor margin (which absorbs Section 301 List 3 at 25% + warehousing + profit) → $90/unit invoice. + $1,000 truck freight to Toronto + Canadian duty 0% + 5% GST = roughly $124,400 CAD landed.

The $50,000 difference is mostly the distributor passing Section 301 (25% on $50,000 of Chinese goods = $12,500 in US tariff) plus their own logistics overhead. For Canadian importers with sufficient volume to manage direct sourcing, the savings on Section 301 alone often justify shifting to direct China procurement.

### 2. Embedded component cost

A Canadian manufacturer assembling a finished product using Chinese-origin sub-components purchased from US suppliers is paying Section 301 in the input price. If Chinese parts are 30% of bill of materials and Section 301 averages 25%, the embedded tariff is roughly 7.5% of the final product's COGS.

### 3. Re-export with drawback (rarely worth it)

Goods that enter the US and are then re-exported to Canada under a duty drawback or temporary import bond can sometimes recover Section 301 paid. Drawback claims must be filed within 5 years and require documentation. The mechanism exists but is rarely worth the administrative cost for sub-six-figure shipments.

Section 301 vs Canadian retaliatory surtaxes — separate stacks

Don't confuse Section 301 with Canada's own retaliatory surtaxes. These are independent, enforced by different governments at different border crossings:

• Section 301: US tariff on Chinese goods. Enforced by US CBP. Canadian importers don't pay this directly.
• SOR/2024-202 (China steel/aluminum 25%): Canadian tariff. Direct payment by Canadian importer at CBSA.
• SOR/2024-187 (China EV/battery/solar 100%): Canadian tariff. Direct payment.
• SOR/2025-154 (China melt-and-pour rules): Canadian tariff. Direct payment.

A single shipment of Chinese steel routed through a US distributor can theoretically face Section 301 (US side) PLUS SOR/2024-202 (Canadian side) for the same 25% rate cumulatively — a stacked total of 50% in tariffs alone, before MFN, GST, and provincial taxes. Direct China-to-Canada sourcing avoids the Section 301 layer.

CUSMA does NOT override Section 301

Common misconception. CUSMA (USMCA) provides preferential treatment for goods that originate in Canada, Mexico, or the US — but only for those that meet rules of origin. Chinese-origin goods imported into the US, regardless of subsequent CUSMA trade with Canada, retain their Chinese origin under CUSMA Chapter 4 rules. The US distributor's resale doesn't transform origin; the goods are still Chinese, still subject to Section 301 on the US import, and still subject to Canadian Chinese-origin surtaxes when crossing into Canada.

This is the "third-country goods" trap. CUSMA only zero-rates goods that originate IN North America; it doesn't launder origin for goods that merely transit.

Section 232 — the other US tariff to know about

Often confused with Section 301. Section 232 of the Trade Expansion Act of 1962 covers national-security tariffs:

• 25% on imported steel (most countries, with carve-outs)
• 10-25% on imported aluminum (originally 10%, raised on some categories)
• Recent expansions to derivative steel/aluminum products

Section 232 applies to most countries including Canada at various points, not just China. The current 2026 Section 232 application to Canadian steel/aluminum imports into the US is what triggers Canada's retaliatory surtaxes under SOR/2025-95 and SOR/2025-118.

How to find out if your specific HS code is on a Section 301 list

The USTR maintains the official Section 301 lists by HTS code (the US 10-digit equivalent of Canada's tariff item). Note: US HTS codes may differ from your Canadian tariff item at the 7-10 digit level — see HTS vs HS code for the mapping.

Practical check: ask your US distributor. Any reputable distributor importing from China knows which Section 301 list their products are on, because they pay it. If they can't answer this question quickly, they may not have the systems to pass through tariff savings if rates change.

Practical implications for Canadian importers

If you're sourcing from China:

• Direct sourcing avoids Section 301 entirely. The single biggest savings opportunity for Canadian importers currently buying via US distributors.
• Total Canadian landed cost is governed by Canadian rates — MFN + Canadian surtax + GST. Use TariffCalc to model the all-in cost without the US distributor markup.
• Container freight from China to Vancouver/Halifax is comparable to China-to-LA. The logistics aren't a barrier.
• Customs brokerage in Canada is straightforward for direct China imports. See how to choose a Canadian customs broker.

If you're sticking with US distributors (for service or timing reasons):

• Negotiate transparency on Section 301 pass-through. Reputable distributors will itemize the embedded tariff or at least disclose what list their products are on.
• Verify origin. A US distributor selling "American-made" product that's actually Chinese-origin may be exposing you to compliance issues if origin is misrepresented at the Canadian border.
• Watch for rate changes. USTR reviews Section 301 lists periodically. The 2024 increases on EVs/batteries hit certain importers hard. Build rate-change clauses into supply contracts.

Tools

• TariffCalc duty calculator — Canadian landed cost (MFN + surtaxes + GST). Does NOT model Section 301 (US-side); use as the comparison baseline for direct vs distributor sourcing.
• HS Code Directory — Canadian classification.
• China Surtax Guide — Canadian-side tariff exposure on Chinese-origin goods.
• HTS vs HS Code — when reverse-translating US HTS data into Canadian tariff items.

Bottom line

Section 301 is a US tariff. It only affects Canadian importers indirectly, through the price US distributors charge for Chinese-origin goods. The most actionable insight: if you're buying significant volumes of Chinese-origin goods via US distributors, modeling direct China-to-Canada sourcing in TariffCalc often reveals a 15-30% landed cost reduction. The Canadian-side tariff bill (Canadian surtax + MFN + GST) doesn't change much, but you eliminate the US distributor's embedded Section 301 cost.

For Canadian goods exporters facing US tariffs INTO the US, that's a different problem — see US retaliatory tariffs.
