The product clause gets the argument. The packing line gets a shrug: “export carton, standard packing.” Then the container arrives with no PO number on the box, mixed SKUs in one master, a wood crate that needs a treatment mark you never asked for, or inner packs that do not match the retailer’s routing guide. None of that is a quality defect in the usual sense. It is a documentation miss. If the PI never named the pack, the mark, and the pallet, you are asking the factory to guess your warehouse’s rules.
This piece is what to lock on the order before they buy cartons.
1. Packing is a specification, not a courtesy
Write the pack as you would write a dimension:
- units per inner, inners per master, masters per pallet
- carton strength (a board grade or a drop/stack requirement — not “strong box”)
- whether retail inner packs must be shop-ready or bulk
- pallet type, dimensions, and whether the load may ship unpalletized
- if wood is used: treated and marked, or plywood / no solid wood
Amazon, a club retailer, and your own aisle do not accept the same pack. “Standard export packing” means the cheapest carton the factory already has in stock.
2. Marks have to be a list, not a picture
A photo of last year’s box is not a mark spec. The PI should list what appears on two adjacent sides of the master, in English (and only the extra language you actually need):
- buyer name or code, PO / PI number, SKU or model
- quantity in the carton, carton number (1 of N)
- gross / net weight and outer dimensions if your broker or warehouse uses them
- origin line if your market requires it on the pack
- handling marks that are real (fragile, this side up) — not a collage of every icon the workshop owns
Say what must not appear: the factory’s name, another customer’s brand, a competing barcode, or a Chinese product title if your buyer-facing carton must stay clean. Marks that only exist in a WeChat image will not match the packing list the broker files.
3. The packing list has to repeat the same story
Carton marks, packing list, commercial invoice, and bill of lading description should use the same product name and the same counts. A credit, a customs entry, or a retailer chargeback often starts with a mismatch among those four — not with a broken latch. If you open an L/C, this alignment is not optional; the bank reads the papers, not the tape on the box.
4. Who pays when the pack is wrong
Put a short remedy on the same page: relabel at their cost before shipment if inspection catches it; or a stated deduction / reprint cost if it lands wrong. Without that line, a mis-marked container becomes a goodwill discount on the next order.
The bottom line
Packing and marks are part of the product you bought. Write the inner/master/pallet, the exact mark lines, the wood rule, and what must stay off the box. A photo of a carton in chat is not a specification.
If you need the packing and shipping-mark wording written into the PI in English and Chinese, I can prepare the clause and issue a stamped set under our bilingual translation company seal when you need one. See what this covers.
Marking and wood-packaging rules vary by destination. Confirm ISPM-15 and retailer routing guides for your market. This article is general sourcing guidance, not customs or legal advice.
