Pre-Production Announcements
Overview
Pre-production announcements let mills signal future surplus availability before the paper is actually produced. This gives buyers visibility into upcoming supply and allows them to plan purchases in advance, reducing the time-to-sale once production completes. It is a V1 (Phase 2, Month 3-4) feature, not in the MVP.
How It Works
- A mill creates a surplus item with
is_pre_production = trueand anestimated_production_date(must be within 30 days) - The item enters the system with status
pre_production - The matching algorithm runs on pre-production items, finding compatible buyers
- Matched buyers see the item in the "Coming Soon" section of their newsletter
- Buyers can express interest (soft reservation, non-binding)
- When the
estimated_production_dateis reached, the status transitions frompre_productiontoavailable - Only at
availablestatus can exclusivity be granted
Status Transition
pre_production --> available --> exclusive --> reserved --> sold
The pre_production to available transition happens automatically when the estimated production date is reached. The mill receives a reminder 3 days before the estimated date to confirm or update specifications (quantity and price may change from estimates).
Business Rules
| Rule | Detail |
|---|---|
| Date constraint | estimated_production_date must be within 30 days |
| Quantity | Estimated, may change when production completes |
| Price | Indicative, may be adjusted |
| Matching | Runs on pre-production items (buyers see them) |
| Exclusivity | NOT granted until status changes to available |
| Buyer interest | Soft reservation only (non-binding) |
| Mill reminder | 3 days before estimated_production_date |
Why This Matters
In traditional surplus trading, mills wait until surplus is physically sitting in the warehouse before offering it. By then, the surplus competes with whatever the broker happens to have in their pipeline. Pre-production announcements give the marketplace a forward-looking advantage:
- Buyers can see what is coming and plan their purchasing cycles
- Mills can gauge demand before production completes
- The marketplace can start container planning earlier (see wiki/concepts/container-assembly)
- Reduces warehouse holding time for mills
Newsletter Integration
Pre-production items appear in a dedicated "Coming Soon" section of the buyer newsletter, clearly distinguished from available surplus. The section shows:
- Paper type, GSM, width, estimated quantity
- Estimated availability date
- CTA: "Express Interest" (non-binding)
