Customer Concentration: Why One Big Buyer Can Close a Small Garment Factory

A small garment factory where one buyer holds more than half the order book is one policy change away from closing, and Tiruppur proved it in 2025. When the US raised tariffs on Indian garments to 50 percent, US orders fell 60 to 70 percent, and industry association TEAMA estimates 750 to 1,000 of the town's roughly 3,200 knitwear units shut down before a trade deal brought the rate down to around 18 percent. The units that closed were not the badly run ones. Many were efficient, quality-consistent factories whose only structural flaw was that their entire order book depended, directly or invisibly, on one market.

What did the 2025 tariff year actually do to small factories?

The tariff did not hit every unit equally, and that is the whole lesson. The US takes roughly 40 percent of Tiruppur's knitwear exports, so exporters serving American buyers saw orders stall, renegotiate, or vanish within weeks. The damage then flowed down the chain: job work units stitching for those exporters lost their work orders without ever having shipped a carton abroad themselves. Units with a spread of export markets and a live domestic line absorbed the shock and kept their machines running. The event lasted months, but the sorting of who survived was decided years earlier, by how each factory had built its order book.

Why does one big buyer feel safe when it is not?

A dominant buyer feels like security because the orders are regular, the styles are familiar, and the payment behaviour is known. The factory tunes its machines, its manpower, and its fabric buying around that one relationship, which makes every additional order from the same buyer cheaper to execute than an order from a new one. That efficiency is real, and it is exactly what deepens the dependence. The risk never shows up in any monthly number the factory watches, because utilisation and dispatch look excellent right up to the day the buyer's own market breaks. Concentration is a risk you only see if you measure it deliberately.

How much of your order book should one buyer hold?

Set a ceiling for yourself and track it monthly, because no auditor will do it for you. A working rule of thumb for a small unit: be uncomfortable when any single buyer crosses 40 percent of your running order book, and treat anything above 60 percent as a structural problem to fix within the year, not a blessing. Measure it by end market too, not just by the name on the work order. Three different exporters who all ship to American brands are one buyer for risk purposes, which is precisely what the job work units that closed in 2025 never counted. The number matters less than the habit of writing it down every month.

Does domestic business protect you when exports fall?

Partly, and the Tiruppur numbers show why it is worth the lower glamour. Of roughly Rs. 74,747 crore of knitwear the town produced in FY2025-26, about Rs. 30,000 crore was domestic, and units feeding that demand kept running through the tariff months while export-only peers stood idle. Domestic orders usually mean smaller lots, tighter payment follow-up, and thinner margins per piece, so treating domestic work as a permanent second leg rather than a slack-season filler is a deliberate cost you accept for stability. A factory that keeps even 25 to 30 percent of capacity on domestic programmes retains living relationships it can scale in a bad export year. Rebuilding those relationships from zero in a crisis is what proved impossible for many units in 2025.

What can a small unit do this quarter to reduce concentration?

Start with an afternoon and a notebook, because the first step is only arithmetic. List every buyer's share of the last six months of order value, then ask your exporter customers which end market each programme ships to, and re-total the list by destination country. Most owners have never seen their own book presented this way, and the number at the top of the list is usually higher than they guessed. From there the moves are unglamorous: quote one new buyer a month even when the book is full, keep one domestic programme alive at all times, and let a deliberately unfamiliar style into the unit each season so your capability does not narrow to one buyer's product. Buyers were already consolidating vendors before the tariffs, as we covered in three market shifts hitting small factories harder than large ones, and concentration risk is the same force seen from the factory's side of the table.
