Currency Depreciation: 5 Ways a Falling Rupee Hits Import-Heavy Retailers

When the rupee weakens against the dollar, a retailer who buys stock from abroad pays more in five separate places, not one.

The goods cost more rupees. The customs duty on them rises. The GST charged at the border rises with it. The cash goes out earlier than it comes back. And the shelf price is usually the last thing to move.

Three of those five hit profit permanently. The GST comes back to you as credit, and the cash-flow gap closes when the stock sells. Knowing which is which is what decides whether you reprice or absorb.

This is currency depreciation, not the depreciation you claim on a fixed asset. Same word, unrelated calculation.

Key Takeaways

• A weaker rupee raises the goods cost, the customs duty and the IGST together
• Duty is calculated at an exchange rate published twice a month, not the rate your bank gave you
• IGST paid at import is recoverable as input tax credit, so it is a cash-flow cost
• Basic Customs Duty is not recoverable, so it joins the goods cost and the pricing lag as a permanent loss
• The shelf price moves last, which is where the squeeze actually shows up

What Does Currency Depreciation Do to an Import Bill?

Currency depreciation means the rupee buys less of another currency than it did before. For an importer that pair is almost always the dollar, because that is what the invoice is written in.

Your supplier invoices you in dollars, and you settle in rupees. Every rupee of movement between the order and the payment changes what the same consignment costs you.

Nothing about the goods has changed. The quantity, the quality and the supplier’s price are all the same. Only the conversion has moved, and it moves through your books in more places than most owners expect.

The window is what makes it bite. A purchase order is raised at one rate, the goods ship weeks later, and payment falls due later still. A cost agreed in March can be settled against a very different rupee.

The rupee trades at a market rate rather than a fixed one, so the level is not something a buyer can plan around. The gap between agreeing a price and paying it is the part you can manage.

1. The Landed Cost Rises Before Anything Reaches the Shelf

This is the obvious one, and it is also the largest single piece of the increase.

A consignment invoiced at the same dollar figure simply converts to more rupees. For an electronics dealer in Madhapur importing the same twenty cartons each quarter, the purchase line grows without a single extra unit arriving.

What matters is that this figure then becomes the base for everything that follows. Duty sits on it. GST sits on the duty. A move in the conversion rate does not add cost once, it adds cost at three levels.

In the purchase records we see, this is also the only one of the five that owners catch straight away. The other four surface later, usually when somebody asks why the margin moved.

2. Customs Duty Rises at a Rate You Do Not Choose

Here is the part that surprises people. The exchange rate that decides your customs duty is not the rate your bank charged you.

Customs values imported goods using a rate the government publishes. Since 4 July 2024 that rate has come from the Exchange Rate Automation Module on ICEGATE.

The ICEGATE user manual says rates for 22 currencies are published “twice a month i.e., on the evening of the first and third Thursdays of the month”. They take effect from midnight the following day.

So your duty is fixed against a rate set on a Thursday, which then holds for about a fortnight. Your bank’s rate moves every day.

That gap is worth using. Once Thursday evening’s rate is out, you know what a bill of entry filed over the next fortnight will be valued at. The rate lookup sits under the Quick Links menu on the ICEGATE site.

On most retail goods, Basic Customs Duty is charged as a percentage of that value. So when the published rate steps up, the duty steps up with it.

3. The GST at the Border Rises, but That Part Comes Back

IGST is charged on imports, and it is not charged on the goods value alone.

GST Council guidance states that “the value of the goods for the purpose of levying Integrated tax shall be assessable value plus Customs Duty levied under the Act”. The duty increase from point two therefore gets taxed as well.

That sounds worse than it is. The same guidance confirms that input tax credit “shall be available to the importer”. It calls the tax paid at import “a pass through to that extent”.

So the extra IGST is a timing cost, not a margin cost. You fund it at the border and recover it against your output tax. Reconciling it properly is the only thing standing between a pass-through and a permanent loss, which is what a GST ITC reconciliation routine is for.

The duty is different. The same guidance is explicit that “the Basic Customs Duty (BCD) and education cess, shall, not be available as input tax credit”. That increase never comes back.

4. Working Capital Is Squeezed Between Order and Sale

A rupee move does not just change the number. It changes when you need the money.

The extra goods cost, the extra duty and the extra IGST are all payable at clearance. The stock then sits until it sells. For a Surat textile wholesaler bringing in trims and fastenings, that gap can run several weeks before a single invoice is raised against it.

Nothing has gone wrong here, and the business may still be perfectly profitable. It simply needs more cash to run the same volume, which is a distinction a cash flow statement shows and a profit figure hides.

5. The Shelf Price Moves Last

Costs move on the day the consignment clears. Prices move when you decide, and often later than that.

Printed price lists, catalogue commitments, dealer schemes and marketplace listings all slow the change down. A kitchenware retailer running a festival promotion has usually locked the price weeks before the stock landed.

This is where the squeeze becomes visible. The margin on paper was set against an old cost, and the actual profit margin on the sale is thinner than the price list suggests.

The lag is rarely a decision anyone made. In most of the books we look at, nobody has revisited the selling price since the last consignment landed, so an old cost is still doing the work.

A Worked Example on One Consignment

The figures below are an example, with invented rates, for a consignment invoiced at USD 20,000 and a Basic Customs Duty of 10%. Surcharges and cess are left out to keep the arithmetic readable; they move the same way.

The consignment costs ₹1,16,820 more. That is the number most owners stop at, and it overstates the damage.

Split it instead. The goods and the duty account for ₹99,000, and none of that returns. The remaining ₹17,820 is IGST, which comes back as credit, so it is a loan to the government until your next return.

Duty rates vary by HSN code, so check your own before copying the percentages.

Where it ends up matters as much as the size of it. The goods cost and the duty both roll into purchases and land in your trading account, pushing up cost of goods sold and pulling gross profit down.

The IGST never belongs there at all. Booking it as a cost is one of the more common errors we see in import records, and it quietly understates the margin on every consignment.

What Can an Importer Actually Do About a Falling Rupee?

None of this is controllable, but the response to it is.

1. Price from replacement cost, not purchase cost. The question is what the next consignment will cost, not what the last one did.
2. Check the published rate before you file. A bill of entry filed either side of a Thursday can land on a different rate.
3. Track duty and IGST separately in your books. Clubbing them into one purchase cost hides the fact that one is recoverable.
4. Reconcile import credit every month. Unclaimed IGST turns a timing cost into a real one.

Petpooja Invoice records purchases with the tax split intact, so the recoverable part stays visible instead of disappearing into a single landed-cost figure. Where stock is the bigger worry, a stock inventory template will show what is still sitting at the older cost.

Conclusion

A falling rupee is not one cost increase. It is a goods cost, a duty, a tax, a cash-flow gap and a pricing lag, and they do not behave the same way.

Of the three that hit profit, the reprice lag is the one you control. Basic Customs Duty you never recover, and the goods cost is simply what the market charged you. The IGST looks alarming on the bill of entry and is the least of your problems, provided the credit is actually claimed.

Retailers who read the signs of profit leaking early tend to be the ones separating those lines rather than watching a single total. Petpooja’s billing and inventory software keeps that split on the record from the purchase entry onward.
