Is revenue from inventory liquidation a taxable income ?

@JamesArthur 

It's revenue (not other income).  If you're only recovering 10% of the product's value (is that 10% of your cost or 10% of retail?), then your COGS is most likely higher than the liquidated value.  Therefore, your expenses (COGS) are higher than your revenue and you have a loss on the liquidation.  The loss reduces net/taxable income.  If the liquidated value exceeds your cost, then you have a gain and an increase in your net/taxable income.     

I totally agree. It's just that the revenue from inventory liquidation isn't included in Amazon 1099k so it got my questioning whether it should be part of the gross revenue. Thank you for helping me to confirm.
