Navigating Canada's New Duty Changes: What Shopify Merchants Need to Know Before August 19th

Hey everyone,

There's been some really important chatter buzzing in the Shopify community recently, and I wanted to dive in and share some key takeaways, especially for those of you dealing with Canadian-origin goods. Our very own community expert, @joshume, kicked off an incredibly insightful discussion about the new US Section 338 proclamations that bring additional duties to 554 Canadian tariff lines starting August 19th. If you're importing from Canada, or even just sending goods through, you absolutely need to pay attention to this.

The Deadline is Closer Than You Think: It's All About Customs Entry

One of the first critical points @joshume highlighted, and it's a big one, is that the August 19th deadline isn't about when you despatch your goods. It's about when they are "entered for consumption, or withdrawn from warehouse for consumption." This means the date that counts is the one your customs entry is filed on.

So, even if your shipment leaves Canada before August 19th, if it clears customs on or after that date, it's subject to the new duties. This effectively pulls the real deadline forward by however long your customs clearance typically takes. It's a subtle but crucial distinction that could easily catch store owners off guard. Your best bet? Talk to whoever files your customs entries and get a specific date for your shipments.

Why You Can't Assume Product Categories Are "In" or "Out"

This was a recurring theme throughout the discussion, and for good reason. It's so tempting to assume that if one type of beauty product is affected, all beauty products are. Or if one food item is, all food items are. But as @joshume's research clearly shows, the category split is surprisingly inconsistent and, frankly, a bit arbitrary from a merchant's perspective.

• Honey is on the list, but maple syrup isn't.
• Lip, eye, and nail make-up are included, but a moisturizer isn't. Imagine being a beauty brand and having half your shipment in scope!
• Cotton and man-made fibre sweatshirts are both on the list, but upholstered wooden seats are not (though other furniture might be).

@Steve_TopNewYork echoed this sentiment perfectly, emphasizing that products that seem very similar from a business standpoint can fall on entirely different tariff lines. This makes verifying the specific HS tariff code for each product absolutely essential. Relying on product descriptions alone just won't cut it here.

The HS Code Deep Dive: 6 Digits vs. 8 Digits

Another excellent point raised by @lumine from the Shopify side, and then clarified by @joshume, was about the precision of HS codes. Many merchants might only have 6-digit HS headings in their product catalogs. The question was, is that enough?

@joshume did the math for us: out of the 554 affected lines, 217 of the 373 unique 6-digit headings are on the list in their entirety. For these, a 6-digit code is enough. But for the other 156 headings, the duties split at a more granular level, meaning you need the full 8-digit code for a definitive answer. Cotton sweatshirts are a great example: the 6-digit code 6110.20 has two lines in the schedule, one on the list and one not. So, a 6-digit code can only tell you "possibly" for about half of the listed items.

This means if you're using a 6-digit catalogue, you might get a "yes" or "no" for some products, but for a significant portion, you'll still need to dig deeper for the 8-digit classification.

Your Crucial First Step: Checking "Country of Origin" in Shopify

Before you even start digging into tariff codes, @lumine brought up a really important, often overlooked point: most Shopify stores don't have the "Country of Origin" field filled in for their products. Across 11 stores they measured, the fill rate was essentially zero for most, excluding one large exporter who already had it in place.

This is your starting line. If you don't know which of your products are Canadian origin, you can't even begin to assess the impact of these changes. So, before you do anything else, you need to:

How to Check Your Products' Country of Origin in Shopify:

1. Go to your Shopify admin.
2. Navigate to Products > All products.
3. Click on a product to edit it.
4. Scroll down to the Variants section. For each variant, click Edit.
5. In the variant details, scroll to the Shipping section.
6. Look for the "Customs information" sub-section. Here you'll find the "Country/Region of origin" field.
7. If this field is empty, you'll need to research and fill it in for all your Canadian-origin products. You can use the bulk editor for this if you have many products.

Once you've identified your Canadian-origin products, then you can move on to checking their specific HS codes.

Actionable Steps for Shopify Merchants

To help you navigate these changes, here's a quick rundown of what you should be doing:

1. Audit Your "Country of Origin" Data: As @lumine stressed, this is paramount. Ensure all your product variants have the correct country of origin set, especially for anything you suspect might be Canadian.
2. Identify Accurate HS Tariff Codes: For all Canadian-origin goods, make sure you have the full 8-digit Harmonized System (HS) tariff code. This is crucial for precise classification.
3. Utilize Resources for Code Checking: @joshume generously shared a free resource from his

4. Consult Your Customs Broker: For the most accurate and up-to-date information regarding your specific shipments and their entry dates, always confirm with your customs broker or whoever handles your customs filings. They can give you the definitive word on what applies to your business.

This isn't the easiest change to navigate, but by being proactive and precise with your product data, you can avoid unexpected duty costs and keep your operations running smoothly.
