In short
- Large projects rarely arrive at once. Machinery, structures and equipment come in waves over months, often from several suppliers.
- Importers tend to plan the project as a whole and the shipments individually — which is the wrong way round. It is the batches that have to be planned.
- An approval consumed on an early batch can leave a later one exposed. This page covers how to sequence a project so the waves do not collide.
Why a project is not one import
Each consignment carries its own declaration, its own release and its own exposure.
- Every batch is assessed on its own — classification, value and restriction apply to each consignment separately.
- Approvals can be batch-specific. A licence or certification used up on one consignment may not be available for the next.
- Restriction categories differ by item. A project contains goods from several categories, each with its own conditions.
- Treating the project as a single approval exercise is the source of most late-stage surprises.
The approvals map
| Item type | Approval tendency | Planning note |
|---|---|---|
| Standard machinery | Generally the lighter route | Still classified per consignment |
| Regulated equipment | Certification or licence before clearance | Budget lead time, not just cost |
| Chemicals or consumables | Additional controls and registration | Often the longest lead item |
| Spare parts and tools | Onward movement | Check temporary and re-export questions early |
Practical point Map the project by item category first, then assign each category to a shipment wave. Planning by supplier instead of by category is what creates collisions.
Sequencing waves so they do not collide
- Start the approval route for the longest-lead item first, even if it ships last. Lead time is driven by the approval, not the vessel.
- Sequence waves so that items sharing an approval or a certificate travel together, where that is possible.
- Do not consume a project-level approval on a partial batch without confirming that the remaining items are still covered.
- Keep a single register of approvals, showing what has been used, what remains and what each wave depends on.
Where project timing goes wrong
| Failure | Cause | Avoidance |
|---|---|---|
| Late batch held | Approval consumed by an earlier wave | Track approval usage across waves |
| Inconsistent classification | Similar items declared differently across batches | Maintain one classification record for the project |
| Storage snowball | Waves arriving faster than clearance | Pace shipping against realistic release timing |
| Unplanned temporary needs | Tools and spares arriving without a return plan | Decide early which items are temporary |
Rule of thumb Plan the last wave first. The item that ships last is often the one that needed the longest approval, and that is what sets the project timeline.
One register, kept current
- List every item category in the project, with its approval route and whether it is temporary or permanent.
- Link each wave to the approvals it depends on, and record what has already been used.
- Reconcile after each release — a project that is reconciled only at the end has no time to correct course.
- Keep the register with the shipping files, so each batch can be checked against the whole.
