Selling Chametz Before Pesach

Most people know they may not eat chametz on Pesach. Fewer register that the prohibition goes considerably further — and that is what the sale of chametz exists to address.

Three prohibitions, not one

Chametz means the five grains — wheat, barley, spelt, rye and oats — exposed to conditions causing fermentation and leavening as defined by halacha.

During Pesach a Jew may not:

• Consume actual chametz, or products containing mixtures of it;
• Derive benefit from it — so selling it, feeding it to an animal, or using it in any way that profits you is also excluded;
• Own it at all.

That third one is the reason for the sale. You are not permitted merely to shut the cupboard and not eat from it. The chametz being yours is itself the problem.

The penalty afterwards

Here is the part that gives the whole business its urgency.

Chametz that remained in a Jew's possession through Pesach carries a penalty: consuming it or deriving benefit from it is prohibited even after Pesach has ended.

So this is not a problem that expires when the festival does. Chametz owned through Pesach does not become permitted again — which is why the question of what happens to a stocked pantry, or a warehouse, is not academic.

What the sale does

The sale transfers ownership of the chametz to a non-Jew before Pesach, so that during the festival it is genuinely not yours. Afterwards, ownership returns.

It is executed through a rav, by delegating power of attorney — you authorise him to act as your agent in making the sale, because a properly constructed transaction of this kind is not something to improvise.

Two things follow from that and are worth stating plainly:

• It is a real sale, not a formality. That is what makes it effective, and it is why it is done through someone competent to construct it.
• The chametz is set aside and not used during Pesach. It belongs to someone else.

Businesses

For a Jewish-owned company holding chametz-containing stock or ingredients, the same requirement applies at a different scale, and the sale is arranged annually as a matter of course. If you own such a business, this is something to have in hand well before Pesach rather than in the last week.

How and when to arrange your sale, and what it should cover, is a question for your rav — and it has a deadline attached, so it is one to ask early.
