Glass Bottle Specifications: A Checklist for Supplier Enquiries

Missing dimensions or mismatched drawing revisions can produce incomparable bottle quotes and rework. Give every supplier the same geometry, capacity, finish, process, quality and packing requirements; mark unknowns for confirmation rather than guessing values.

This checklist covers stock and custom bottles. For shape and sourcing choices, start with glass bottle types and sourcing.

Copy the blank specification record or go to the grouped checklist.

Start with the drawing

Ask each supplier for a drawing of the exact article and quote against it. Every other line in the enquiry should point back to that drawing.

Cetie, the European glass packaging technical body, lists a data sheet whose stated aim is to help customers build meaningful specifications for the manufacturing and filling of glass containers (DT12.00). It also lists data sheets on standard tolerances for capacity, height, diameter, verticality and base-to-mouth parallelism of the finish (DT02.00), and a glossary of glass container visual defects (DT26.01) that notes severity values should be agreed between the glassmaker and the filler. These are public catalog summaries, not reviewed editions of the full documents. Record the exact document revision agreed with the supplier before citing it as a specification.

Blank specification record

Copy this table into your own document and add a row for each required field from the checklist. Leave values open until supported; “Pending” requires an owner and evidence, not an assumed pass. Use the sample-stage comparison to identify what a sample represents.

The specification checklist

Container geometry and weight

Capacity and fill

Cetie DT09.00 gives factors to convert the mass of water to true volume, and refers to ISO 8106 for gravimetric capacity determination. Ask which method the supplier uses to report capacity so numbers are comparable across quotes.

Finish and closure

Glass color and appearance

Strength and special requirements

Decoration, labeling and marking

Quality, packing and delivery

Incoming packaging and receiving checklist

Empty glass arrives in one of two formats, and the enquiry should name the one you want. Waterloo Container, a glass distributor, describes bulk glass as bottles placed directly on pallets at the factory without corrugated cases, with layers divided by rigid tier sheets, strapped, and the whole pallet wrapped, often with corner boards. Cased glass arrives in corrugated boxes, usually with partitions. An integrator’s description of a glass-plant palletizing cell (Kaufman Engineered Systems) shows bulk pallets built from pallets, sheets and top frames. Your depalletizing or unpacking method decides which format works, so settle it with the depalletizer and infeed guide before you fix the packing lines below.

Incoming packaging: what to state

Receiving checklist

Use this at the dock for each delivery, and record and photograph problems before signing for the load:

1. Delivery documents match the order: article reference, drawing revision, quantity and lot numbers.
2. Each pallet label is legible and matches the documents.
3. Wrap, straps and corner boards are intact, and the load is upright and not leaning or shifted.
4. No broken glass, loose bottles or moisture is visible under the wrap.
5. Tier sheets are present between layers, clean, dry and not torn; the top frame is present if specified.
6. Bottles from the top layer show no visible finish damage, scuffing or haze.
7. Certificates of conformity or test reports required by the supply agreement have arrived.
8. Pallets with problems are labeled and held apart until the supplier responds.

The checks match what the depalletizer has to handle: pallet condition, load stability and sheet removal. Protection of filled cases on the way out is a separate topic, covered in case packing and palletizing.

Published requirement, supplier claim and your requirement

Keep three kinds of statement separate in the enquiry and in your notes. A published standard or data sheet is a reference both sides can read. A supplier’s catalog figure is a supplier claim, so request the drawing behind it. Your own requirement, such as a maximum height for your line, is yours to set, and you should write it as a requirement, not as a general fact. Stock and custom projects may have different drawing and tooling arrangements; confirm who controls revisions. The cost and document differences are covered in stock vs. custom glass bottles.

Questions to send suppliers

1. Please provide the drawing for this article, including the revision, finish designation, brimful capacity, weight and tolerances.
2. Which standard or internal specification governs your dimensional and capacity tolerances?
3. How is brimful capacity measured, and what are your reported results for recent lots?
4. What is the fill point for the nominal capacity, and what headspace do you recommend for my product and filling temperature?
5. What defect classification and sampling plan do you use, and can they be written into the supply agreement?
6. What strength tests do you run, and what pressure rating applies if my product is carbonated?
7. Which closure and liner combinations have you validated on this finish?
8. What are the packing options, and what documentation ships with each lot?
9. If I change the closure, label type or fill temperature later, what needs to be revalidated?

When the bottle is part of a line purchase, the same data feeds the equipment request in the bottling equipment RFQ checklist.

Evidence and limitations

This checklist is an editorial synthesis of published data sheets and distributor and supplier descriptions. It cannot replace the standard, the drawing or the supply agreement. The relevant standards depend on the market: Cetie documents are European and voluntary, and North American buyers often use GPI finish conventions and supplier-specific drawings. Requirements for strength, headspace, color and defects depend on the product, the line and the supplier, and the values must be agreed in writing for each item.
