A tariff headline does not translate directly into a lobster price at checkout. The effect depends on the actual product, its origin and processing, the rules in force when it enters a country, and how businesses absorb or pass on costs. Currency movements add another variable.
Why there is no single tariff number for every order
Live lobster, frozen tails, and prepared lobster products can have different customs classifications. The country of shipment and the product’s qualifying origin are also different questions. Trade-agreement treatment requires the relevant origin rules and documentation; it should not be assumed merely because a shipment crosses the U.S.–Canada border.
CBP’s USMCA origin-certification guidance explains the information supporting a claim under that agreement. It is one part of evaluating an import, not a substitute for checking the current tariff schedule and any additional measures in effect on the entry date.

How exchange rates enter the calculation
A buyer paying a Canadian-dollar invoice with U.S. dollars is affected by the exchange rate. As a purely hypothetical example, a C$100 invoice would cost US$75 at US$0.75 per Canadian dollar, or US$70 at US$0.70, before fees and other costs. These are illustrative numbers, not current or historical exchange-rate quotes.
A favorable currency move can reduce one cost, but it does not automatically cancel a tariff. The invoice currency, customs value, timing, contracts, and currency-conversion costs all affect the result.
Other costs still matter
- Supply: the quantity and sizes available influence purchasing choices.
- Processing: whole lobster, tails, and picked meat require different work and packaging.
- Transport: live, chilled, and frozen products need suitable handling.
- Demand: holidays and other buying patterns can affect competition for inventory.
A business may adjust its margin, buying schedule, or product mix instead of passing every cost change directly to the next buyer. There is no dependable one-for-one formula from a news headline to a customer’s final price.
What shoppers can compare
Compare the species and origin shown on the listing, the product format, net package weight, and total delivered price. Shell-on lobster and picked meat are not equivalent quantities. For a specific purchase, the current product listing and checkout total are more useful than an old exchange-rate or tariff estimate.
This article explains the price mechanisms rather than quoting a live duty rate. Businesses making an import decision should check the applicable official tariff information for the product and entry date.
