Leather Exports from Karachi: Moisture, Fumigation and Container Stuffing

Leather goods are among Pakistan's best-known exports — jackets and garments from Karachi and Lahore, gloves from Sialkot, footwear and accessories from across the country. They are also one of the cargoes most likely to arrive damaged without a single carton being dropped. Mould, odour and stains from moisture inside the container cause claims that can wipe out the margin on an order.

Why Leather Is Moisture-Sensitive

Leather holds moisture. When a sealed container travels from warm, humid Karachi into cooler waters, moisture evaporates from the cargo and the packing, condenses on the container roof and walls, and drips back onto the cartons. Days in a warm container are enough for mould to start on leather and on the cartons themselves.

Packing That Prevents Claims

Check the container before loading: dry floor, no holes or light leaks, no smells, doors that close tightly. Avoid stuffing in the rain, and photograph the stuffing for your claim file.

Worked example — the jacket order: A Karachi garment exporter shipped leather jackets to Europe in sealed polybags without desiccants during the monsoon. On arrival, a third of the cartons showed mould spots. The next season, breathable packing, desiccants and a lined container brought the shipment in clean.

Chemical Compliance

Buyers in Europe and North America test leather for restricted substances. The EU's REACH regulation limits chromium VI in leather articles that come into contact with skin, and many brands also test for azo dyes and other substances on their restricted lists. These are product issues, but they affect logistics: shipments can be held or rejected after arrival if test reports are missing or fail. Keep test reports matched to each production lot and send them with the shipping documents when the buyer asks.

Fumigation and Wood Packaging

Finished leather goods do not usually need plant-health certificates, but wooden pallets and crates must meet ISPM-15 treatment rules, and some buyers ask for container fumigation against insects. Agree in advance whether fumigation is required, which treatment the destination accepts, and how long the container must stay sealed afterwards. Make sure the fumigation certificate matches the container number and dates on the bill of lading.

Sea or Air?

Most leather volume moves by sea in full containers or LCL. Air suits samples, urgent replenishment and high-value small orders — and avoids long exposure to container humidity. For seasonal fashion lines, a split shipment often works: the main order by sea, early-delivery styles by air.

Checklist

1. Confirm the buyer's packing, testing and fumigation requirements before production ends.
2. Dry and inspect the goods before they are packed.
3. Use breathable packing, desiccants and a lined container.
4. Inspect and photograph the container before and during stuffing.
5. Match test reports and certificates to the shipment.
6. Insure the cargo with cover that includes moisture damage, and check the exclusions.

Common Mistakes

• Packing leather while it still carries moisture from finishing or humid storage
• Sealing goods in airtight polybags with no desiccant
• Accepting a damp or smelly container to save a day
• Stuffing during rain without cover at the loading bay
• Sending test reports that refer to a different production lot
• Choosing cargo insurance that excludes moisture or mould damage

Each of these is cheap to prevent and expensive to argue about once the buyer has opened the cartons.
