Packing belongs in the purchase order
Include the packing requirement in the purchase order: bar dimensions and surface, quantity, bundle-mass limit, transport modes, exposure, lifting arrangements, and destination restrictions. Request a packing proposal where the design is not fixed and have it reviewed before material is bundled.
Marks and documents
Define which identifiers appear on the bar or bundle tag, packing list, material certificate, and inspection report. Include order line, grade, heat or lot, dimensions, piece count, and mass where required. Check that splitting or combining bundles leaves the material traceable and update the packing list after any change.
Protection for the actual transport route
Choose corrosion protection, separators, wrapping, end caps, and supports for the supplied surface and expected handling. Keep banding and approved lifting arrangements distinct. Identify inspection access and photographs required before packing is closed, and confirm that protection is compatible with the buyer's next operation.
Destination-market details
Confirm destination, consignee marks, label wording, package restrictions, and any wood-packaging or other route-specific requirements with the responsible shipping parties. Schedule document and packing approval before the loading deadline. Reconcile final bundle quantities and marks with the shipment release record.
Package inputs from the transport route
State the bar form and surface, dimensions, quantity, bundle-mass limit, transport route, exposure, lifting method, and destination restrictions. ASTM D3951 gives general commercial-packaging guidance; it does not approve a particular order. Ask for a package proposal and keep bundle design separate from later CTU securing.

Packing and marking choices
| Control | Required input | Responsible party | Acceptance evidence |
|---|---|---|---|
| Bundle and preservation | Surface, route exposure, bundle mass, supports, wrap, protection | Seller or named packer | Approved drawing, materials list, and packing record |
| Handling marks | Actual lift, storage, orientation, mass, and destination needs | Buyer and package designer | Marking artwork matched to written instructions |
| CTU loading and securing | Cargo masses, geometry, CTU data, forces, blocking, bracing, lashing | Named CTU packer and competent reviewer | Approved load plan and completion evidence |
| Wood packaging | Component type, destination applicability, approved treatment and mark evidence | Wood-packaging provider and exporter | Visible mark record and component reconciliation |
Marks that match the document set
Define which identity and mass fields appear on bars, tags, packing lists, invoices, and inspection records. Match symbols to written handling. Require pre-closure photos, bundle reconciliation, and discrepancies; bands are not lift points unless expressly approved.

RFQ example
Item: Steel bars, [grade / standard], [surface], [diameter x length], [quantity]
Route basis: [origin] to [destination] by [modes], planned transit [period], expected storage [conditions / period], unloading by [equipment]
Bundle design: Supplier to propose unitisation, compatible preservation, nonabrasive separators, protected ends, verified maximum gross mass [buyer limit], lifting access, and tag locations
Handling: Written lift and storage instructions required; select ISO 780 symbols only where necessary and consistent with the approved package
Marking: PO/item, grade, standard, heat or lot if ordered, size, count, bundle number, net/gross mass, destination, and buyer reference; reconcile to packing list and inspection dossier
CTU: Named packer to submit cargo-unit load and securing plan using actual cargo and CTU data; bands are not lifting points unless expressly approved
Wood: Identify all natural-wood supports or dunnage and provide destination-applicable ISPM 15 treatment and mark evidence where required
Evidence: Packing drawing, materials list, pre-closure photos, mass record, bundle list, CTU completion record, and deviations before release
Approval: No unapproved substitution of preservation, support, marking, or loading routeQuestions buyers ask
What packing wording should buyers include for steel bar orders?
State bundle method, surface protection, rust-prevention requirement if any, bundle marking, shipping marks, document matching needs, destination, and any buyer-specific label or packing-list wording.
Why do bundle marks matter for steel bar shipments?
Bundle marks help connect physical goods with grade, heat number or batch, size, quantity, packing list, certificate, and buyer reference when traceability or receiving inspection is required.
When should packing requirements be confirmed?
Packing requirements should be confirmed before order release or shipment preparation when they affect handling, marking, rust prevention, inspection release, export documents, or destination-market instructions.
RFQ checklist
- Packing method, bundle weight preference, and handling requirement if specified
- Rust-prevention, wrapping, end protection, or surface protection requirement
- Bundle tag details such as grade, size, heat number or batch, quantity, and buyer reference
- Shipping marks, consignee marks, PO number, project name, or destination labels
- Packing list, invoice, certificate, inspection release, and document matching needs
- Surface condition and whether protection wording should match black, peeled, ground, or machined bar
- Destination port, country, unloading or warehouse instructions if relevant
- Third-party inspection, photo record, or buyer approval requirement before shipment
- State product surface, dimensions, quantity, route, transit, storage, and unloading assumptions.
- Set a verified maximum bundle mass and identify permitted lifting equipment and access points.
- Require an approved package drawing, preservation system, separators, supports, and end protection.
- Use only necessary ISO 780 symbols and pair them with clear written handling instructions.
- Assign CTU packing and securing to a named party using actual cargo and unit data.
- Identify regulated natural-wood components and destination-applicable ISPM 15 evidence.
- Reconcile bundle tags, mass records, packing lists, invoices, and inspection references.
- Define pre-closure photo, discrepancy, approval, and packing-change notification requirements.
