A lab order ships incomplete when the order line names the item but not the lot, the cold rule or the paperwork the carrier expects. Record the lot at the pick scan. Hold cold items for a safe dispatch day. Block the packing bench until every document is attached.
The order line knows the item, not the lot
A certificate of analysis belongs to a lot. An order line only names a catalogue item. Between the two stands a picker who grabs a bottle from the nearest shelf, and the shelf may hold lot A at the front and lot B behind it.
The folder holds lot A’s certificate. Lot B is in the box. The customer’s quality officer spots the mismatch at goods receipt, and the reagent sits in quarantine until someone in your office finds and emails the right PDF.
Capture the lot at the moment of picking. Nothing else closes the gap.
- Scan the lot label at pick, not at dispatch
- Store each certificate under item code plus lot
- Print the matching certificate with the packing slip
- Block a pick from an expired or quarantined lot
Cold items packed on a Friday
Cold stock is fussy. Antibodies, restriction enzymes, polymerase mixes and serum each carry a limit on hours in transit and a pack type, whether gel packs, wet ice or dry ice.
A Friday afternoon pick breaks that rule without anyone deciding to. The parcel sits in a carrier depot all weekend because the customer’s dock closes on Friday evening, and by Monday the gel packs are warm to the touch.
The fix is a dispatch calendar. Cold lines are held back from the packing queue unless the carrier’s transit days land before the receiving dock closes. Late orders then roll to Monday on their own.
Chemicals travel with paperwork the carrier expects
Solvents, acids and oxidisers fall under different carrier rules. The outer carton may need a hazard diamond, a UN number, a limited quantity mark or a signed shipper’s declaration, depending on the class and the route.
The safety data sheet is a separate matter. Customers expect the current revision in the language of the destination country, and a box that arrives without it can be refused at the receiving bay.
Order screens rarely carry any of this. Add hazard class, packing group and cold flag as fields on the product record so the packing bench can read them. Check the carrier’s current rules for every route you serve.
- Hazard class and UN number on the product record
- Safety data sheet revision and language
- Label template for the outer carton
- Route limits, for example air versus road
Put a gate at the packing bench
Training people to remember five things fails on busy days. A gate does not. The system should refuse to mark a parcel as packed until every check has passed, whatever the queue looks like and however loudly the customer is chasing.
Keep the gate short. Lot recorded, certificate attached, cold rule met, data sheet inside, hazard label printed. A failed check sends the parcel to a hold shelf. Each gets a reason code.
Do not let the packer override it. A supervisor can, and the override is logged against the order with who approved it and when, which makes repeat offenders easy to find.
Count the misses by cause
A box will still arrive short now and then. Send the certificate that day. Then log the miss under a single cause: wrong lot, no certificate, warm pack, no data sheet or wrong label.
A month of tagged misses points at the weakest step. Sometimes the culprit is not your bench at all but one supplier whose lots reach your dock without certificates, so the paper was never there to pack.
Pull the last twenty complaint emails today. Tag each by cause. The biggest tag becomes your first gate rule.
Packing bench gate checklist
A single page for each packing bench. It lists five tick boxes in order: lot scanned, certificate printed, cold rule and ship day met, safety data sheet inside, hazard label on the carton. A reason code column sends failures to the hold shelf, beside a supervisor initial field, and the back lists the cold rule for each carrier route.

Can a certificate of analysis be sent by email instead of in the box?
Many customers accept a link or a PDF by email, but some quality systems want the paper at goods receipt. Ask each account which they need. Store the answer on the customer record.
Who decides which days cold items can ship?
Dispatch does, working from the carrier’s transit time and the customer’s receiving hours. Put the result in the system as a rule per route. Packers then never decide it parcel by parcel, and the buyer sees an honest ship date at checkout.
Do all chemicals need a safety data sheet?
Hazardous ones usually do, and many customers ask for the sheet with every shipment. Rules differ by country. Check with your compliance adviser and your carrier before you ship a new product line abroad.
How do we link a lot to a customer if a recall happens?
Capture the lot on every pick. A search on the lot number then lists each order and customer that received it, with dispatch dates, so a recall reaches the right people that afternoon.
