We built the trust layer this trade never had.

On one side: charity trading arms and collectors holding unsorted clothing they could not resell at home. Their buyers were whoever turned up with a lorry and a price per tonne. Payment terms slipped. Weights were disputed after the fact. Where the goods ended up was, at best, a phone number in another country. That is an uncomfortable answer for an organisation whose name is on the donation bank.

On the other side: sorting houses in Pakistan with real capacity and real customers, who could not reach verified supply without going through brokers. Some of those brokers made their margin on duty, not on service: under-invoicing, misdeclaring grades, moving goods meant for the freezone into the domestic market. Every one of those shortcuts undercut the sorters who were paying properly, and left suppliers exposed to a trade they could not see.

The goods moved anyway. What did not move was trust, so it was bought from intermediaries, at a price both ends paid.

Pakistan is among the largest importers of used clothing in the world by value , and Karachi is where most of it is opened, graded and sent on: to domestic markets, and re-exported to Afghanistan, Central Asia, the Middle East and Africa .

The trade runs on two legal routes. Freezone units in the Export Processing Zones import under bond, sort, and re-export, with a limited share permitted into the domestic market on payment of duty: the "80/20" arrangement . Domestic importers pay customs duty and taxes at import and sell into local markets. Both are legitimate. The problem is that from London or Toronto they look the same, and so does the broker who claims to be either.

What changed is that most of a buyer's status can now be checked against systems rather than taken on reference: FBR registration and Active Taxpayer status, Pakistan Single Window customs records, EPZA licensing. At the same time, charities and collectors are under growing pressure to evidence where their textiles go . The verification could finally be done properly, and suppliers had a reason to want it.

There is no shortage of secondhand clothing in the UK, the US, Canada or Australia. There is a shortage of buyers a charity can put its name next to. So before we asked a single supplier for stock, we went to Karachi.

We signed a small number of sorting houses , EPZ units and domestic importers, who passed the full KYB standard including a site visit, and who were willing to commit to written buying specifications: grade, monthly volume, a price band per kilo CIF Karachi, payment terms, and a claim window.

That changed the conversation with suppliers. We were no longer offering a promise of demand. We were offering a named, verified buyer type, a spec, and a price. The supply side followed from that.

The first containers were run concierge-style. We stood in yards and opened bales. We filmed loading and photographed seals. We chased fumigation certificates, checked bill-of-lading drafts line by line against the buyer's KYB file, and coordinated deposit and balance between two banks in two time zones. When the box was unstuffed in Karachi, we were on the phone.

Every manual step became a rule. An early draft bill of lading named a clearing agent as consignee: that became the consignee rule. A disagreement about moisture became the loading-evidence checklist. A claim raised three weeks after arrival became the claim window.

The standard on our Trust & Verification page is those rules, written down.
