About Marginify

Why we built it

We built Marginify because working out what an import really costs takes too much time.

By the time a product reaches your warehouse, the duty rate, the freight quote and the exchange rate have each had a chance to move, and the number you worked out last quarter is wrong. Many importers keep that number in a spreadsheet and fix it when something looks off. It is slow, and it is easy to miss a change.

We wanted that work to look after itself. Marginify keeps the landed cost current, tells you when a change touches a product, and shows the price that protects your margin, so you can spend that time on the business instead.

It is not built for one industry. Apparel, furniture, electronics, food and auto parts all have their own codes and their own countries, but the sum underneath is the same, and Marginify carries the rates for every chapter of the US and Canadian schedules. If a product has an HS code and a country of origin, it can work out the landed cost.

Marginify is new, and we are still learning what importers need from it. If something is missing for your kind of product, email us. We read every message.

What it does

Landed cost is what a product really costs you by the time it is in your warehouse: the item, freight, insurance, duty and customs brokerage. Duty is the part that moves. Marginify works it out for every product from the official US and Canadian tariff schedules, keeps a history of each margin, and emails you when a rate change or an official tariff notice touches a product you sell. For each product it also shows the lowest price that keeps your margin floor.

• A free calculator for one product, with no account.
• A duty rate lookup for any code in either schedule, and a log of recent tariff notices.
• Entry summaries (CBP 7501, CBSA CAD) read for you, with every figure checked and the extra tariffs you paid shown line by line.
• Landed costs sent to the purchase cost of your items in QuickBooks Online or Xero.

Who builds it

Marginify is built and run by Arya Zarei, the founder. Email to [email protected] goes to Arya Zarei, and there is a support page with the response times.

Where the numbers come from

• US duty rates: the Harmonized Tariff Schedule, published by the US International Trade Commission. Canadian duty rates: the Customs Tariff, published by the Canada Border Services Agency. Both are checked every six hours (now HTS 2026 Rev. 22 and Customs Tariff T2026-2, last updated 6 hours ago).
• Tariff notices: the US Federal Register (USTR, Commerce, CBP and the President) and the Canada Gazette, read every day.
• Exchange rates: the Bank of Canada’s daily rates.

Every figure is an estimate for planning, not a customs-compliance determination, and Marginify is not a licensed customs broker. Extra tariffs such as Section 301 or 232 are never applied for you: Marginify flags the ones that may apply and you confirm the rate with your broker. The security page sets out what we store and what we do not do.
