Top Compliance Mistakes New Importers Make — And How to Avoid Them

Entering the world of importing can be exciting—new products, global opportunities, and the promise of growth. But for new importers, the excitement often comes with a steep learning curve. One of the most overlooked areas? Customs compliance. Even minor missteps can lead to costly delays, penalties, and lost revenue. If you're importing goods into Canada or elsewhere, here are the most common compliance mistakes you must avoid—and how to set things right from day one.

Mistake #1: Misclassifying Your Products

Every product that crosses a border needs to be classified using an HS (Harmonised System) code. It sounds simple, but many new importers guess the code or pick one that seems "close enough.”

Why it matters: A wrong code could mean you’re paying too much duty—or worse, not enough, which can trigger audits and fines.

How to avoid it: Use the Canada Tariff Finder or consult with a licensed customs broker who can review your goods and determine the accurate classification.

Mistake #2: Incorrect Valuation of Goods

Customs authorities calculate duties and taxes based on your shipment’s declared value. Inexperienced importers sometimes undervalue goods to cut costs or forget to include shipping, insurance, or commissions.

Why it matters: Inaccurate valuation is a red flag for customs and can result in shipment seizures or delayed clearance.

How to avoid it: Understand Canada’s valuation rules and always provide a truthful, complete commercial invoice.

Mistake #3: Missing or Incomplete Documentation

Importing isn’t just about moving boxes—it’s about moving boxes with the proper paperwork. A missing bill of lading or an incomplete commercial invoice can hold up your entire shipment.

Why it matters: Customs won’t release your goods until they receive and verify all required documentation.

How to avoid it: Create a document checklist for every shipment, including commercial invoices, packing lists, certificates of origin, and permits if needed.

Mistake #4: Overlooking Canada-Specific Import Regulations

Each country has its own import rules, and Canada is no exception. New importers often skip the fine print, especially if they only deal with domestic suppliers.

Why it matters: Certain goods (like food or electronics) might require special permits, or agencies like the CFIA could flag your shipment.

How to avoid it: Research the regulatory body that governs your goods and check if they require pre-approvals or inspections.

Mistake #5: Misunderstanding the De Minimis Threshold

If you’re shipping low-value goods (under CAD 40 for duty or $150 for taxes), you might assume you’re in the clear. Not quite.

Why it matters: Misusing De Minimis to dodge duties can be fraud. Also, your package

might still require declaration or inspection.

How to avoid it: Know when De Minimis applies and how to declare your shipment properly.

Mistake #6: Not Preparing for Duty and Tax Payments

You’ve imported the goods. Now comes the bill. Some new importers forget to budget for GST, PST, or duties, or don’t pay them on time.

Why it matters: Non-payment leads to delays or legal trouble.

How to avoid it: Set up a customs account with the CBSA and ensure you’re ready to pay duties or taxes electronically.

Mistake #7: Skipping the Use of a Certified Customs Broker

While you can technically clear your goods, that doesn’t mean you should. DIY importers often miss critical compliance steps.

Why it matters: Even one overlooked detail can lead to fines, delays, or shipment rejections.

How to avoid it: Work with a certified customs broker who understands compliance, classification, valuation, and documentation inside and out.

Building a Smarter Import Compliance Strategy

Compliance doesn’t have to be stressful. Here’s how to simplify:

Use digital tools to track and archive your import paperwork

Automate duty and tax payments with your broker

Schedule periodic reviews to ensure compliance is still on track

Educate your team with updated training and SOPs
