Is zakat due on commercial goods that their owner acquired as a debt for one year?

Zakat is obligatory on electrical appliances sold by a merchant because they are trade goods. He should appraise them at the end of the year (hawl). If their market value reaches the nisab by themselves, or when combined with money, zakat becomes obligatory on them. He may deduct the value of his debts to the seller from their value, and pay zakat on the remainder if it does not fall below the nisab. The hawl for trade goods is the hawl of the capital with which they were purchased. If they were purchased on credit, their hawl is after one year from their purchase.
