An incomplete Booking Request does more than trigger follow-up emails. For machinery and electronic-component shipments, the wrong routing, equipment type, packed weight or an undeclared lithium battery can cause rejection, equipment changes, lost sailing options or repeated amendments. The common root cause is using the commercial invoice as if it were an operational data sheet, or treating the Booking Request as the final Shipping Instruction. This article maps the required information, source documents, approval owners and control points before a booking is submitted.

QUICK FACTS

A request, not an acceptance

The request allows a carrier or forwarder to assess routing, space, equipment and cargo acceptance; it is not the confirmation.

Six core data groups

Parties and rate reference; route; equipment; cargo; payment; special requirements.

Estimated weight is not VGM

Booking weight needs a packing basis. VGM is submitted separately once the packed-container mass can be verified and sufficiently in advance by the applicable cut-off for the stowage plan.

Special cargo must be declared early

DG, reefer, OOG, SOC, batteries, liquids or magnetized items may need dedicated data and approval.

Booking is not Shipping Instruction

SI provides the final bill-of-lading and manifest data after the booking has been confirmed.

SCOPE OF APPLICATION

This article primarily covers ocean-freight bookings for FCL machinery, spare parts and electronic components. It also includes extensions for dangerous, refrigerated, out-of-gauge and project cargo.

Applies to direct carrier bookings and bookings through a forwarder/NVOCC.
The party controlling the booking may be the Buyer, Exporter, Shipper or an appointed agent depending on the sales contract, delivery term, quotation and contract of carriage; do not infer it from a role label alone.
Covers port, ramp and carrier-haulage arrangements; mandatory fields vary by carrier, lane and service.
Does not replace Shipping Instructions, VGM, a Dangerous Goods Declaration or customs documentation.
There is no single universal statutory Booking Request form for every ocean carrier.

TERMS AND DEFINITIONS

Term	Meaning	Operational role
Booking Request	A space/equipment request submitted by the booking party.	Enables assessment of schedule, allocation, equipment, service scope and cargo acceptance.
Booking Confirmation	Carrier/NVOCC response accepting or arranging the request.	Controls booking number, routing, cut-offs, depot, terminal, equipment and remarks.
Shipping Instruction – SI	Final bill-of-lading instructions sent by the shipper/forwarder.	Feeds the draft B/L or sea waybill and transport/manifest data.
Booking Party	The party entering the request in the carrier platform or sending it by an agreed channel.	It may be the shipper, exporter, buyer, forwarder or booking agent under the contract; it is not automatically the cargo owner or freight payer.
Merchant Haulage	Inland transport arranged by the cargo interest.	The booking focuses on the agreed port/ramp interface.
Carrier Haulage	Inland transport arranged by the carrier.	Requires pickup/delivery address, contacts, timing and site-access data.
SOC / COC	Shipper’s Own Container / Carrier’s Own Container.	Changes equipment sourcing, container checks and interchange procedures.
VGM	Verified Gross Mass of the packed container.	Prepared when the packed-container mass can be verified and submitted sufficiently in advance for stowage planning; not the booking estimate.

NATURE AND OPERATING MECHANISM

A Booking Request is a decision dataset. The carrier uses it to test routing, allocation, equipment availability, stowage feasibility and cargo acceptability. The goal is not maximum text; it is accurate data that changes the acceptance decision.

Carrier decision	Main inputs	Possible result
Space acceptance	POL/POD, preferred ETD, quotation/contract, TEU quantity, commodity.	Confirmed, pending validation, alternate sailing or rejection.
Equipment allocation	Type/size, quantity, SOC/COC, weight, package dimensions.	Allocated, substitution proposed or equipment pending.
Cargo acceptance	Operational commodity, DG/reefer/OOG status, batteries, liquids, high value.	Additional documents, special approval or rejection.
Inland service	Place of Receipt/Delivery, address, pickup date and access constraints.	Carrier haulage confirmed, extra charge or scope adjustment.
Rating and payment	Quotation/contract number, prepaid/collect, payer and payment location.	Correct tariff attached or booking held for clarification.

Control rule: A post-confirmation change to routing, equipment, container quantity, weight or DG/OOG status may require a fresh review and may affect allocation.

WHAT SHOULD THE BOOKING REQUEST SHOW?

Information group	Recommended fields	Source	Control point
1. Parties and contacts	Booking party; provisional shipper; forwarder; contact name, email, phone; customer reference.	Service agreement, PO and approved company master data.	Correct legal account and authorized amendment/cancellation contact.
2. Rate reference	Quotation/contract/rate agreement; named account; freight payer.	Approved quotation, service contract or rate confirmation.	Validity, lane, commodity, equipment and account must match.
3. Route and schedule	Place of Receipt; POL; POD; Place of Delivery; preferred ETD; direct/transshipment; service mode.	Delivery plan, carrier schedule, Incoterms and named place.	Do not confuse POR with POL or use an ETD without its location.
4. Equipment	Container size/type; quantity; COC/SOC; substitution permission; empty pickup date/depot.	Packing plan, container loading plan and quotation.	Check capacity, floor load, door dimensions and weight distribution.
5. Cargo	Operational commodity description; packages; packing type; estimated gross/net weight; CBM; largest package dimensions; HS if required.	Preliminary PL, drawings, datasheet, BOM and packing plan.	Avoid vague terms such as “parts”; establish the packed-weight basis.
6. Inland scope	Merchant/Carrier Haulage; pickup/delivery address; positioning date; trucker/contact; site restrictions.	Warehouse plan, factory address and site survey where needed.	Confirm container access, opening hours, road limits and lifting arrangements.
7. Payment	Prepaid/Collect; payment location; freight payer; invoice party if requested.	Sales contract, Incoterms and logistics quotation.	Do not derive payer solely from Incoterms.
8. Special requirements	DG, reefer, OOG, SOC, breakbulk, high value, battery, no-stacking, top-load or ventilation.	SDS, DG data, packing drawings, temperature protocol and survey.	Flag at booking, not after container release.
9. Operational remarks	Preferred depot/terminal, split shipment, multiple commodities, preliminary B/L needs and internal deadlines.	Packing and document workflow.	A remark remains a request until confirmed by the carrier.

ADDITIONAL DATA FOR SPECIAL CARGO

Cargo type	Booking data	Supporting evidence	Common failure
Dangerous goods	UN number, Proper Shipping Name, class, packing group where applicable, flash point where relevant, marine-pollutant status, packages and quantity.	SDS, DGD/Multimodal Dangerous Goods Form and technical approval data.	Sending an SDS without a valid transport classification.
Components with batteries	Battery chemistry, standalone/packed with/contained in equipment, quantity, Wh or lithium content and condition.	SDS, UN 38.3 test summary and carrier-required packing evidence.	Hiding the battery under “electronic parts”.
Reefer	Set temperature, ventilation, humidity/dehumidification, controlled atmosphere, pre-cooling and genset needs.	Temperature protocol, product specification and reefer instruction.	Providing temperature only or mixing °C and °F.
OOG / Flat Rack / Open Top	Packed dimensions, over-height/width/length, package weight, center of gravity and lifting/lashing points.	Packing drawings, photos, method statement, survey or lashing plan where required.	Using bare-machine dimensions instead of final packed dimensions.
Machinery with oils/gases/liquids	Type and quantity retained, pressure, drained/purged condition and possible DG status.	SDS, manufacturer declaration and technical statement.	Declaring only “machine” while ignoring hydraulic oil, gas or pressure vessels.
SOC	Container number/type, CSC plate status and voyage use.	CSC plate details, container data and survey if requested.	No acceptance check at POL/POD or depot.

The IMDG Code provides the international framework for packaged dangerous goods by sea, but the carrier, port and voyage still determine the booking data and approval package.

BOOKING REQUEST VS BOOKING CONFIRMATION VS SHIPPING INSTRUCTION

Criterion	Booking Request	Booking Confirmation	Shipping Instruction
Issued by	Booking party to carrier/forwarder.	Carrier or NVOCC.	Shipper/forwarder to carrier/NVOCC.
Purpose	Request space, schedule, equipment and service.	Confirm accepted/arranged booking conditions.	Provide final B/L and transport-document data.
Core data	Routing, equipment, quantity, commodity, estimated weight, special cargo and payer.	Booking number, vessel/voyage, cut-offs, depot, terminal, equipment and remarks.	Shipper/consignee/notify, description, packages, weights, marks and B/L terms.
Control value	A request; not evidence that every remark is accepted.	Read every version and all conditions; revisions may be issued.	Primary input for the draft B/L; errors can flow into manifest data.
Timing	Early enough to secure space and equipment.	Review immediately and after every revision.	Before the SI cut-off in the latest confirmation.

Warning: A “received” email or booking acknowledgement is not necessarily a Booking Confirmation. Empty pickup and stuffing should follow a confirmed status with verified equipment, depot, terminal and cut-offs.

DOCUMENTS AND DATA TO CHECK BEFORE SUBMISSION

Document/data	Owner	Locks which fields	Insufficient when
Quotation/rate confirmation/service contract	Buyer/Exporter, Procurement, Forwarder	Lane, equipment, rate, surcharges, validity, payer and scope.	Expired or mismatched lane/commodity.
Cargo-readiness plan	Supplier/Factory/Exporter	Ready date, stuffing duration, container count and terminal-delivery plan.	Only an uncommitted estimated date exists.
Preliminary Packing List	Supplier/Factory	Packages, packing type, net/gross, CBM and largest dimensions.	Pallet/crate weight is excluded or packing is not frozen.
Catalogue/datasheet/BOM	Supplier/Engineering	Commodity identity, model, batteries/liquids and handling needs.	Generic product name or wrong model.
Container loading plan	Warehouse/Engineering/Forwarder	Equipment choice, package allocation, floor load and securing points.	Door dimensions and weight distribution are not checked.
SDS/DG/reefer/OOG package	Supplier, DG specialist, QA	Special-cargo approval and equipment.	Provided only after a standard booking was confirmed.
Party master/payment instruction	Buyer/Exporter/Finance	Booking party, shipper, payer, prepaid/collect and invoice party.	Legal name or customer code differs from the rate contract.

BOOKING PREPARATION AND APPROVAL PROCESS

Freeze the transport scope

Define port/ramp/door scope, Incoterms and named place, the contractual booking controller, and merchant or carrier haulage. Incoterms are only one input; booking authority and payer must be locked by the specific agreements.

Freeze cargo and packing inputs

Obtain a confirmed preliminary PL, final-packed dimensions, special-cargo status and accountable cargo-ready date.

Validate rate and equipment

Check quotation/contract validity and match lane, container type, commodity and quantity.

Prepare the booking draft

Enter all data groups and identify every assumption instead of guessing.

Run two approvals

Supplier/Factory approves cargo facts; the party controlling carriage under the contract approves routing, equipment, sailing, payer and service scope.

Submit and track status

Record submission time, reference number, clarification requests and response owner.

Review Booking Confirmation

Compare request and confirmation: voyage, depot, terminal, cut-offs, equipment, special remarks and pending conditions.

Control changes

Any change to readiness, weight, equipment, DG/OOG status or route returns to impact review and revised confirmation.

CARRIAGE-CONTROLLING PARTY – SUPPLIER – FORWARDER RESPONSIBILITY MATRIX

Task	Party controlling carriage (Buyer/Exporter/Shipper under the contract)	Supplier/Factory	Forwarder/Booking Agent (if appointed)	Approval point
Scope and freight payer	Leads and approves under the sales contract, quotation and contract of carriage.	Provides location, timing and delivery capability.	Advises scope, routing and carrier constraints within the service scope.	Carriage-controlling party.
Readiness and packing data	Tracks commitment and accepts the operating schedule.	Owns source cargo facts, packages, weights, dimensions and technical characteristics.	Checks booking completeness and does not alter technical facts independently.	Supplier confirms data; carriage-controlling party accepts schedule.
Routing and equipment	Approves timing, cost and contractual scope.	Confirms stuffing feasibility and site constraints.	Recommends schedule/equipment against data and availability.	Carriage-controlling party.
DG/OOG/reefer status	Ensures the special-cargo trigger is not bypassed.	Provides accurate technical evidence and confirms actual condition.	Submits to the carrier and follows approval if within scope.	No party may downgrade or conceal cargo status.
Booking Request preparation	Provides master data, rate reference and booking authority.	Provides cargo and packing data.	Executes only when appointed as Booking Party/Agent; otherwise supports data preparation.	Booking Party defined by contract.
Booking Confirmation review	Approves sailing, scope and commercial conditions.	Checks empty release, stuffing date and ability to meet cut-offs.	Checks cut-offs, depot, terminal, equipment, special remarks and revisions.	Carriage-controlling party releases execution.
VGM and SI	Identifies the contractual shipper, VGM signatory/authorizer and SI approver.	Provides actual post-packing figures and source-document data.	Submits within authority, monitors feedback and does not replace source-data responsibility.	Per SOP and contract; never assume the forwarder owns all responsibility.

RISKS AND COMMON ERRORS

Error	Cause	Impact	Control
Wrong POL/POD or missing POR	Port and receipt point are confused or copied from an old booking.	Wrong routing, depot/ICD and inland cost.	Use location codes and a route map.
Wrong container type	Selection based only on CBM.	Stuffing failure, overload or last-minute equipment change.	Check door, floor load, weight distribution and securing.
Understated booking weight	PL excludes crates/pallets or allocation is incomplete.	Carrier amendment, stowage impact and equipment issues.	Document the estimate basis and update after packing changes.
Undeclared battery/DG feature	Vague commodity and missing SDS.	Cancellation, delayed DG approval and safety exposure.	Mandatory battery/oil/gas/aerosol/chemical questions.
Booking treated as SI	Assumption that booking data becomes final B/L data.	Wrong parties, packages, description or manifest.	Separate SI and draft-B/L approval gates.
Confirmation revision ignored	Only the first version is stored.	Missed vessel, depot, terminal or cut-off changes.	Version control and change notification.
Incoterms used to guess payer	Rate and carrier instructions are not checked.	Wrong prepaid/collect or invoice party.	Lock payer through quotation and written confirmation.
Unconfirmed remark treated as accepted	No carrier response is checked.	Missing no-stack, genset, special equipment or inland service.	Require the condition in confirmation or a separate approval.

FAQ

1. Must a Booking Request include Consignee and Notify Party?

Not universally. Some platforms request party details early; others complete Consignee/Notify in SI. Follow carrier mandatory fields and avoid entering unapproved final-party data.

2. Is an HS code mandatory in the Booking Request?

It depends on carrier, lane and cargo. If requested, it should align with the commodity description, but it must not replace a meaningful operational description.

3. Are estimated weight and VGM the same?

No. Estimated weight supports booking and equipment planning. VGM is the verified mass of the packed container and must be submitted sufficiently in advance by the applicable cut-off for stowage planning.

4. Does a confirmed booking guarantee loading?

Not absolutely. Loading still depends on terminal delivery, VGM, SI, DG/OOG approval, equipment status and carrier conditions.

5. Can the commercial invoice be used as the Booking Request?

It provides only part of the commercial data. Route, equipment, readiness, packing dimensions, special-cargo status and haulage data require additional sources.

6. May the forwarder choose the vessel and container without approval?

The forwarder may recommend them within its service scope, but the contractual carriage-controlling party must approve and the Supplier/Factory must confirm packing feasibility. A forwarder is not automatically the Booking Party for every shipment.

7. When must the booking be amended?

When data affecting allocation or acceptance changes: routing, ETD, container type/quantity, weight, commodity, DG/OOG/reefer status, inland points or payer.
