Why does lot age matter?

Germination declines with lot age and storage conditions. Always ask for the production year, the lot number and the test date on the ISTA analysis — a recent certificate on an old lot tells you very little on its own.

Is paying upfront ever acceptable?

For small sample orders, yes. For commercial volumes, use a letter of credit or another documentary instrument so payment is released against shipping documents rather than against a promise.

10 mistakes buyers make when choosing seed suppliers

Hard-won lessons: skipping ISTA, ordering a season's worth before trialling, accepting old lots, paying upfront without LC, and seven more.

Direct answer

What is the most common mistake in seed procurement?

Ordering a full season's requirement before trialling the variety locally. Catalogue performance is recorded under the breeder's conditions, not yours, and disease pressure and climate stress are what decide field results.

Key takeaways

1. Skipping ISTA germination and purity: Without an ISTA analysis you are buying on faith.
2. No trial before commercial order: Even with a known breeder, run a 100g–1kg trial under your conditions before committing to a season's volume.
3. Accepting old lots: Year of production matters.
4. Paying upfront without an LC: Wire transfer to a new supplier with no LC and no escrow is how buyers lose money.
5. Ignoring resistance packages: A cheaper hybrid without the disease resistance you need is more expensive in season.

After hundreds of buyer-side sourcing engagements, the same mistakes recur. Avoid these and your seed sourcing improves more than from any single change in supplier.

1. Skipping ISTA germination and purity

Without an ISTA analysis you are buying on faith. Demand it on every quote.

2. No trial before commercial order

Even with a known breeder, run a 100g–1kg trial under your conditions before committing to a season's volume.

3. Accepting old lots

Year of production matters. Seed loses germination over time, especially in poor storage. Ask for the production year.

4. Paying upfront without an LC

Wire transfer to a new supplier with no LC and no escrow is how buyers lose money. Use a confirmed LC for first orders.

5. Ignoring resistance packages

A cheaper hybrid without the disease resistance you need is more expensive in season.

6. No country-of-origin awareness

Some destinations restrict imports from specific countries. Confirm before you order.

7. Skipping the documentation pack

Phyto, origin, ISTA, invoice, packing list. Missing any one of these holds the shipment.

8. Negotiating only on price

Lead time, trial support and after-sale agronomy matter more than the last 5%.

9. Single-source dependency

Always have a verified second supplier for your top three SKUs.

10. No buyer-side intermediary

Going direct to a single breeder gives you their offer, not the market. A buyer-side broker like SeedMatchGroup runs parallel sourcing — see Cross-Border Seed Procurement, Seed Letter of Credit Financing and Urgent Seed Sourcing.
