リピート注文前の6つのチェック

Repeat orders are where complacency costs money. These six checks take very little time and cover the failure modes that actually occur.

The six checks

• •Compare the new COA against the retained reference batch, not against the specification alone. Drift inside the specification is still drift.
• •Confirm the grade and production site are unchanged. Ask directly if any raw material source changed since the last shipment.
• •Re-confirm packing and labelling. Requirements drift when your own warehouse or customer changes.
• •Check the price basis — Incoterm, named port, packing, payment terms and validity.
• •Check the production date against the shelf life, particularly for insoluble sulphur and moisture-sensitive fillers.
• •Confirm the current compliance declaration for your destination market; restriction lists are updated and an old declaration may no longer match.

Keep a shipment log

Record grade, batch number, COA values, arrival condition and any deviation. A six-shipment log makes trends obvious and is the strongest evidence you can bring to a supplier conversation.

Escalate early

If a value moves outside your historical band but still inside the specification, raise it before the next order rather than after the next problem. Suppliers respond much better to a trend question than to a claim. ## Need the documents or today's price?
