Frequently Asked Questions

Does this calculate the exact amount I will pay at the border?

No, this provides an estimate. CBSA uses the exchange rate on the day of clearance, and duty rates can change. Always budget 10-15% extra for fluctuations. For exact amounts, you can request a ruling from CBSA or use their CARM (Customs Assessment and Revenue Management) portal.

What is the $20/$40/$60 exemption rule?

Gifts valued under $60 CAD are duty and tax exempt. Regular goods under $20 CAD are exempt. However, these exemptions do NOT apply to commercial imports (even samples), alcohol, tobacco, or goods shipped by courier—these are always taxable regardless of value.

Can I claim the GST/HST paid on imports as an Input Tax Credit (ITC)?

Yes, if you are a GST/HST registrant and the import is for business purposes, you can claim the tax paid as an ITC on your GST/HST return. Ensure you keep the CBSA Form B15 (Casual Goods Accounting Document) or the courier's commercial invoice showing the tax paid.

What if I don't know the HS code?

The AI will estimate based on your description, but you should verify using the Canadian Customs Tariff Schedule or request an Advance Ruling from CBSA. Using the wrong code can result in underpaid duties (penalties) or overpaid duties (lost cash flow).
