Merchant Center added a warranty attribute for Canadian listings covered by Quebec's Bill 29

Merchant Center introduced an optional warranty attribute so merchants selling Shopping ads and free listings in Canada can state the legal warranty length Quebec's Bill 29 requires on certain new electronics and appliances. Google says display on Shopping ads and free listings begins later this year.

The attribute takes a duration sub-attribute as a whole number plus duration_unit set to month or year, which must be year for Quebec, and an optional mileage sub-attribute in kilometres for vehicle ads. Quebec's rules cover 14 product types: six years for stoves, refrigerators, freezers, air conditioners and heat pumps; five for washing machines, dryers and dishwashers; four for televisions; and three for laptops, desktops, game consoles, cell phones and tablets. Supplying the attribute is optional and merchants remain responsible for compliance. The Merchant API expanded the same attribute to all products in its October release, with durations in months or years.
