More sourcing guides for glass packaging — MOQ, lead times, samples, payment and certificates — are collected in one place.
Export support for glass bottles means planning four things together from the first quotation: ocean-grade packing, container loading, the export document set for your destination, and a written procedure for breakage claims. Importers seldom lose money on the bottle; the losses come from cartons built for domestic trucking, a forwarder booked before carton dimensions were settled, or a certificate nobody asked for until the container was at the port. With export-grade packing, transit breakage of 0.5 to 1.0 percent is a realistic target. Where this sits in the wider buying process is laid out in our glass packaging sourcing guides.
The four workstreams to have in writing before production
Failed import projects nearly always break down in one of four areas. A credible offer addresses each of them on paper before the order goes into production.
Export packing
Cartons are specified for a sea voyage: five-ply corrugated board at a defined burst strength, molded pulp or corrugated dividers matched to the bottle shoulder, and a pallet pattern worked out against the container's internal width. Divider selection, pallet patterns and 40HQ loading calculations are explained in our guide to the packing specification for glass bottles.
Freight and container planning
Choosing a 20GP or a 40HQ affects unit cost, so it belongs at quotation stage and should not be left to the forwarder. A 40HQ offers roughly 76 cubic meters, but glass is dense. Most bottle programs run out of volume before weight, whereas heavy 750ml spirits bottles can reach the 26-tonne payload ceiling first. We work out both limits for each SKU so that offers can be compared on landed cost and not on ex-works figures alone.
Export documents
A food-contact glass shipment normally needs a commercial invoice, packing list, bill of lading instructions and certificate of origin. Depending on destination it may also need FORM A, a health certificate or a food-contact declaration of compliance. Missing or mismatched paperwork is the main reason glass shipments run up port demurrage. Each document is described in our guide to export documentation for glass packaging.
After-sales and claims
Some glass will break in transit. What matters is that the allowance and the remedy are agreed beforehand, which the purchase contract should record before production starts.
Planning figures for three common formats
These are typical packing values for planning. The carton and pallet plan for your own SKU is confirmed against the project drawings and issued on the packing specification sheet ahead of mass production; neck finish, decoration and closure details are likewise confirmed per project.
| Parameter | 750ml wine bottle (300g) | 500ml spirits bottle (550g) | 370ml food jar (280g) |
|---|---|---|---|
| Bottle weight | ~300 g | ~550 g | ~280 g |
| Pieces per carton and divider | 12 pcs, corrugated | 12 pcs, pulp | 24 pcs, corrugated |
| Carton size (L×W×H) | ~400×300×330 mm | ~400×300×290 mm | ~410×280×260 mm |
| Carton gross weight | ~5.5 kg | ~8.4 kg | ~8.6 kg |
| Cartons per pallet | 100 (5 layers × 20) | 80 (4 layers × 20) | 96 (6 layers × 16) |
| Pallets per 40HQ | ~44 | ~40 | ~42 |
| Pieces per 40HQ | ~52,800 | ~38,400 | ~96,768 |
| Transit breakage target | ≤1.0% | ≤0.8% | ≤0.8% |
How the buying route changes what support you need
The emphasis shifts with the way the glass is bought. Custom programs lean on coordinated support most heavily, because mold logistics, decoration vendors and documents all sit on one critical path.
| Factor | Stock mold | Modified stock |
|---|---|---|
| Tooling | None | Neck or finish tooling |
| Samples | Drawn from warehouse stock | Require new finish trials |
| Suits | A first import or a market test | An established SKU that needs brand differentiation |
| Support emphasis | Consolidation and quick paperwork | QC on decoration, plus upgraded packing |
Read any quotation as a stack of cost lines, not one number. When an offer comes in noticeably under the market, the packing line is usually where the saving was found, and that line protects everything else in the container. Tooling, sampling and freight are quoted per project and depend on the mold, the decoration, the quantity and the freight terms.
Three questions that test a supplier's export capability
Ask these before committing, and note how quickly and concretely the answers arrive.
- "Can I see the packing specification sheet you would issue for this bottle?" An operation that controls its packing can issue one promptly. A trader without that control cannot produce it.
- "What paperwork went with your last three shipments to my country?" Experience is country-specific. Fluency in food-contact declarations for the EU says nothing about whether the supplier has ever handled a Saudi SASO or a US FDA prior notice.
- "How was your most recent breakage claim handled?" Every exporter has had claims. Those with real support describe a procedure; the rest offer excuses.
To verify the answers, use our guides to pre-shipment quality inspection and to auditing a glass bottle factory.
What to include in a landed-cost request
A landed-cost figure can only be worked out with the following in your first message when you request a quote:
- The bottle format and its capacity; a drawing or photo of the container you have in mind also works
- Expected quantity for each SKU, and the yearly volume
- The port of destination and the Incoterm you prefer: FOB, CIF or DDP
- Regulatory or food-contact rules that apply in your market, such as EU 1935/2004 or FDA
- The delivery date you are aiming for, and whether goods from other suppliers must be consolidated
Frequently asked questions
How does one-stop export support differ from an ordinary factory quote?
An ordinary quote covers the bottle and basic cartons. Coordinated export support adds engineered packing, a container loading plan, the complete document set for the destination, freight booking under your chosen Incoterm and a written breakage-claims procedure, all handled by a single team answerable for how the container arrives and not only for how it left the gate.
Which Incoterm suits a first-time importer?
FOB is the practical default. You appoint the forwarder and see the real freight cost, and the supplier deals with export clearance. CIF appears convenient but conceals freight margins and leaves destination charges as a surprise. DDP fits small trial orders where you want a single invoice and no involvement in logistics, at a higher unit cost.
How much breakage is acceptable on an ocean shipment?
With dividers, 5-ply cartons and shrink-wrapped pallets, 0.5 to 1.0 percent is realistic. Results that stay above 2 percent point to a packing fault, not bad luck. State the allowance and the remedy in the purchase contract before production.
Can bottles from my other suppliers go in the same container?
Yes. Mention it in the brief so the loading plan accounts for it.
Which documents come with a food-contact glass shipment to the EU?
The usual set is an invoice and packing list, the bill of lading, a certificate of origin, and a Declaration of Compliance that cites EU Regulation 1935/2004 and is backed by migration test reports. FORM A or EUR.1 is added where your country has preference arrangements. We check the list against your destination before the proforma invoice is issued.
How are breakage claims settled?
Claims terms, along with samples and inspection, are agreed per project before the order is placed.
