Select plywood glue and emission requirements from the intended use, moisture exposure, panel construction and importing market. This guide explains how UF, MUF and phenolic/PF systems are commonly applied; how MR, exterior bond and WBP wording should be completed in a purchase specification; and how E0, E1, CARB Phase 2, TSCA Title VI, CANFER and JAS/F-star differ. It also shows the test methods, reports, certification records, labels and lot details buyers can request. Use the comparison tables to align quotations on the same construction and test basis, then send the selected requirements with finished dimensions, quantity, packing and destination for a product-specific quotation.
Prepare your specificationA plywood bond type describes how the adhesive lines between veneers are expected to perform under stated moisture and exposure conditions.
MR is a common trade description for plywood intended for dry interiors or occasional humidity, depending on CUZI PLY and market.
MUF is melamine-urea-formaldehyde adhesive used in selected interior and moisture-resistant plywood constructions.
PF refers to phenol-formaldehyde adhesive, commonly used for exterior-oriented, formwork and selected marine or structural plywood constructions.
WBP is widely used in trade for weather-and-boil-proof or water-boil-proof performance.
Begin with the exterior bond requirement, then add the veneer grade, core construction, product standard, marking and performance requirements for the intended use.
Compare them by test method, unit, product coverage, jurisdiction and document requirement.
Include the panel construction, intended use, exposure, destination, bond requirement, emission requirement, dimensions, quantity and requested documents.
The glue line is tested for the intended exposure. Formaldehyde release is assessed for a defined product under a named method or destination programme.
The adhesive-application plate shows one complete veneer continuously supported through the glue spreader.

| A-bond | regional bond-class term | Applicable AS/NZS option and exact product scope | Product standard/certification supporting documentation | An EN class or universal exterior claim |
| EN 314 bonding class | standard requirement option | EN 314-1 method plus EN 314-2 class | Scope-matched report | Product grade, marine or structural status |
| Marine plywood | product standard/market file | Named marine product standard and complete construction | Product, bond, veneer and document and test requirements | Exterior glue alone |
| Structural plywood | product standard/design file | Named structural standard, grade and supporting documentation | Certification, marking and design values as required | Exterior glue alone |
Bond-test preparation separates dry racks, treatment trays and identification controls before testing.
E0, E1, CARB Phase 2, TSCA Title VI, CANFER and JAS/F-star use different definitions and programme requirements. Compare quotations only when the same method and product coverage are stated.

Before the purchase order
No. MR is commercial shorthand for a moisture-resistant option and is not a universal waterproof product or finished-assembly claim. Name the exposure, method and acceptance.
Replace WBP alone with the exact product, glue or bond specifications, pre-treatment, test method, acceptance criteria and supporting documentation required for the destination.
No. MUF is an adhesive chemistry. Melamine Plywood is a faced product whose decorative surface, substrate glue and balance must be specified separately.
No. PF can describe the veneer glue line; phenolic film is a surface overlay. Each interface and its supporting documentation scope are separate.
No. A marine option also controls veneer species/quality, core, construction, dimensions and the applicable product standard and supporting documentation.
No. Structural classification requires the applicable product standard, grade, testing, certification/marking and design data, not only glue-line durability.
No. E1 is tied to a particular standard requirements; E0 is used differently across markets and buyers. Always name method, unit, scope and acceptance.
They are separate US federal and California programmes with closely aligned limits for covered products, but programme, TPC, labels and records must be checked for the exact option.
Canadian rules and guidance determine the option. US programme documents may support a file, but the importer must confirm Canadian product scope, certification, testing, label and records.
EU REACH Entry 77 applies to relevant articles from 6 August 2026 under Appendix 14 conditions. It is an article placing-on-market restriction, not a renaming of E1.
Not automatically. Coverage depends on the tested product family, construction, line, sampling, method, programme and accepting authority. Changes trigger scope review.
Include use, exposure, destination, construction, current bond language, nominated bond and emission methods/programmes, supporting documentation/label needs, dimensions, quantity, packing, timing and attachments.
If a test method or emission programme has not been selected, describe the application and importing country; CUZI PLY will propose suitable options for quotation.
