Scenario: you want imported edges on the shelf before first snow and are not sure when to place the order. Direct answer: start at the date you expect to plow and subtract each stage, using durations your suppliers and forwarder have confirmed in writing. I give no standard durations, because they differ by supplier, route and season.
The backward plan
| Step (counting back) | What happens | Duration to confirm | Who confirms |
|---|---|---|---|
| 0. First plowing date | Edges are fitted and tested before this | Fitting and test time in your shop | You |
| 1. Ready-to-fit date | Parts inspected and sorted | Inspection and counting | You |
| 2. Delivery to your door | Final trucking from port or airport | Inland transit | Forwarder or carrier |
| 3. Customs clearance | Entry filed and released | Typical hold and release time | Customs broker |
| 4. Ocean or air transit | Cargo in transit | Door-to-door estimate | Forwarder |
| 5. Export handling | Booking, export clearance, loading | Cut-off dates | Supplier and forwarder |
| 6. Production | Parts made and checked | Quoted production time, plus holiday closures | Supplier |
| 7. Sample or drawing approval | You approve before production | Your review time and supplier’s response | Both |
| 8. Quote and decision | Compare quotes, choose a supplier | Your internal approval time | You |
How to use it
Counting back is the only way to catch a lead time that does not fit the season.
- Write your real first-plow date at the top, not the calendar start of winter.
- Fill each duration with a number from a person who will do the work, and note the date you asked.
- Add the total, then add a buffer for the steps with the least predictable timing. Customs and ocean transit are common weak points, but your own experience may differ.
- If the resulting order date has already passed, decide between air freight, a smaller quantity, a local stock purchase or accepting a late arrival.
If the dates do not fit
When the result says the order date was last month, do not hide the gap. List the realistic fixes, such as a smaller air shipment for critical trucks, local stock for the first weeks, or a staged delivery, and attach a cost and a risk to each. Then choose deliberately and tell the people who plow what stock to expect. A visible gap is easier to manage than a surprise in the first storm.
Common planning mistakes
Planning errors are usually omissions rather than wrong numbers.
- Counting production time but not the approval cycle before it.
- Ignoring factory closures during holidays; see our note on factory calendars.
- Using the supplier’s best-case number for every stage.
Boundary: durations vary by supplier and route and are not given here. Confirm every number with the party responsible. This is planning advice, not a promise of arrival dates.
