DACH Matcha: Lot Architecture at Import

If a matcha consignment has been held at an EU entry point, the first question management asks is "whose mistake was it?" — the supplier's documents, your freight forwarder, or official control. In our experience with DACH buyers, the most common answer is none of the three. It is lot architecture: how many lot numbers you declared inside one consignment, and whether the Swiss leg was planned at order time or improvised after arrival.

This article is about shipment and lot structure for a DACH programme — one EU entry point plus a non-EU Swiss leg. It does not restate the product specification. If your open question is what residue limits the powder itself must meet, read the DACH residue spec article instead. If you want the same structural logic for a different regime, Singapore's SFA document split covers a single-agency system with different consignment logic, and the UK BTOM piece covers a single post-Brexit border rather than a two-border programme.

Why lot count, not kilograms, is the cost driver

A consignment is a customs and official-control unit. A lot is a traceability and analysis unit. Buyers tend to optimize the first (fewer shipments, lower freight per kilogram) and let the second happen by accident — the mill assigns lot numbers by production run, the invoice lists them, and the consignment now carries five lots instead of one.

That matters because several costs scale with the number of lots, not with the weight:

• Analysis and certificates. A certificate of analysis describes a lot. Five lots in one box means five CoAs, five sets of values to reconcile against your internal spec, and five records to keep. If your QA system requires each lot to be released individually, five lots means five release decisions.
• Sampling exposure. Where official sampling is applied per lot rather than per consignment, declaring more lots widens the surface on which a sample can be drawn. Control frequency and the sampling unit are set by the competent authority and change over time — verify the current treatment of Japanese green tea powder at your entry point with the responsible authority before you fix your structure, rather than assuming last year's pattern still holds.
• Re-labelling for the Swiss leg. If Switzerland is served out of an EU warehouse, labels are reworked by lot. Fine lot granularity means more label versions, more rework stations, more scope for a mismatch between the label, the CoA and the delivery note.
• Stock release friction. One lot on hold blocks only that lot — which sounds like an argument for many lots. It is, but only if your warehouse and ERP can actually quarantine at lot level. If they cannot, many lots give you the paperwork cost without the isolation benefit.

None of this is an argument for always consolidating. It is an argument for choosing the number deliberately, before the order is placed, because once the mill has run the batches and printed the lot codes, the architecture is fixed.

The two DACH-specific complications

One market, two customs territories

Germany and Austria sit inside the EU customs and food-law area. Switzerland does not. A DACH programme therefore crosses a border twice if Swiss volume is served from a German or Austrian warehouse: once at EU entry, once again into Switzerland. Each crossing is its own declaration, and the Swiss step typically wants documentation that traces back to the lot, not to your EU warehouse receipt.

You have two structures:

• EU-first: all volume enters the EU, Swiss demand is re-exported from the EU warehouse. One Japanese origin shipment, one set of import documents, but a second declaration and usually a second labelling pass for the Swiss portion.
• Split at origin: the Swiss portion ships separately from Japan directly to Switzerland. Two shipments from origin, two sets of documents, higher freight per kilogram on the smaller leg, but no re-export step and no mixed-label warehouse.

Which is cheaper is a volume question. Below the point where a direct Swiss shipment is commercially sensible, EU-first wins on freight and loses on handling. Above it, the direct route usually removes more work than it adds. The point is that this decision determines lot granularity: in the EU-first model you want Swiss-destined volume on its own lot numbers so that the re-label pass touches whole lots rather than partial ones.

Labels are decided at order time, not at the warehouse

Swiss labelling requirements are not identical to EU ones, and both are reviewed on their own schedules. We do not restate them here; confirm the current requirements with the Swiss and EU authorities or your regulatory advisor at the time you design the label. What we can say structurally is that if the Swiss label differs at all, you are choosing between printing two label versions at origin against two lot groups, or printing one and reworking part of it later. The first choice must be made when the order is placed. The second is made for you, by default, if you do nothing.

The lot architecture worksheet

Work through this before your next order, not after the next hold. It takes about twenty minutes and produces a figure you can put into a quote request.

Step 1 — Inputs

1. Annual volume of each matcha grade, in kilograms.
2. Order cadence you can finance and store: quarterly, every four months, twice a year.
3. Number of finished SKUs this powder feeds, and whether any of them are private-label for a customer who imposes their own lot or CoA rules.
4. Swiss share of volume, and whether it is served from an EU warehouse or imported directly today.
5. Quarantine capability: can your WMS/ERP hold a single lot while releasing others in the same delivery? Yes or no. This is the single input most buyers answer wrongly, so check it with your warehouse, not from memory.
6. Stock-out tolerance: how many days of cover you keep, and what happens to the menu or production plan if one lot is blocked for the length of a typical laboratory turnaround.

Step 2 — Derive lots per consignment

Divide the consignment weight by the largest lot size your supplier can produce as a single blend. That is your floor — the minimum number of lots that is physically possible. Then add lots only where you can name the reason:

• A private-label customer contractually requires dedicated lots. Add one group.
• Swiss-destined volume needs its own label version. Add one group.
• Your quarantine answer in Step 1 was "yes" and a full-consignment hold would break your stock cover. Add enough groups that losing one does not stop the line.

If none of those apply, stay at the floor. Every additional lot above the floor costs you a CoA, a release decision and a traceability record for the life of the product.

Step 3 — Assign document ownership

For each document, write down whether it is issued per lot or per consignment, and who holds the original. The common failure is a document that everyone assumes someone else issues per lot. Typical allocation: certificate of analysis and the mill's production record are per lot and come from the supplier; commercial invoice, packing list and the import declaration are per consignment and come from you or your forwarder; the Swiss re-export or import declaration is per consignment on the Swiss leg; labels are per lot group. Fill in the actual names and companies, not the roles.

Step 4 — Turn it into supplier questions

Send these to your Japanese supplier with the order enquiry, before price is agreed:

• What is the maximum weight you can produce and certify as a single blended lot for this grade?
• Can lot numbers be assigned to our specification — for example, one lot per destination country — or are they fixed by production run?
• Is the CoA issued per production lot or per blended batch, and what is the lead time and cost difference between the two?
• What is the blending window — how far before shipment must we fix the lot structure?
• Can two label versions be applied at origin against separate lot groups in the same shipment?
• If a lot is held at EU entry, what retained sample and production records can you release, and how quickly?

Any supplier that cannot answer the first three in writing is a supplier whose lot architecture you do not control — which means you will keep absorbing the cost of decisions made in someone else's production office.

Diagnosing a hold you already had

If you are reading this because of a specific incident, reconstruct it in this order. Was the consignment selected for control at all, or was it a documentary query? If it was a documentary query, which document, and was that document issued per lot or per consignment? If it was selected for control, was the whole consignment held or a single lot? Was the delay the laboratory turnaround, or the time it took to obtain a missing record from Japan?

The answers separate the three explanations your management is asking about. A missing or inconsistent record points at document ownership — fixable in Step 3. A whole-consignment hold on a multi-lot shipment that your warehouse could not partially release points at architecture — fixable in Step 2. A clean, routine control with normal laboratory turnaround points at neither; that is the cost of importing food, and the only lever is stock cover.

What this changes in your next quote request

Most matcha quotes are requested as a price per kilogram against a grade and an annual volume. That request cannot price the thing this article is about. A quote that assumes one blended lot per quarter and a quote that assumes four certified lots per quarter are different pieces of work for the mill, and the difference shows up in certification and packing, not in the leaf.

So state your lot architecture in the request: grade, annual volume, consignments per year, lots per consignment, number of label versions, and whether Switzerland is served from the EU or directly. You will get a price you can compare, and you will find out before committing whether fine-grained lots are worth what they cost you.

Request a wholesale quote with your lot structure stated — tell us the lots per consignment and the Swiss arrangement you are considering, and we will price against it so you can see the cost of granularity before you order.

Regulatory note: EU official control and sampling practice for third-country tea products, and Swiss food law alignment, are both revised on their own schedules. Treat every regulatory point above as something to verify with the competent authority at the time you act on it.
