All material must be free from heavy metal compounds as a result of treatment e.g. Copper Chrome Arsenate (CCA ) – Identified by green colour.
All material must be free from plasterboard, MDF, plywood, chipboard, hardboard, OSB, laminated, bonded or glued products.

Downgrading

Loads that contain material outside this specification e.g. oversize, metal, excessive fines or moisture, will be subject to a proportional price reduction / downgrade.

 

Collection

Spot Testing

Loads may be subject to spot tests on arrival. Sub-standard deliveries will result in telephone notification to the supplier of any problem(s) found. This will be followed up with a fax or e-mail, giving exact details and confirming what action is to be taken.

 

Rejection

Boomeco reserve the right to downgrade, enact a quantity or price reduction or reject any load for reasons of non compliance with this specification and after the sampling and testing procedures have been carried out, the supplier notified accordingly, and subsequent deliveries cancelled until the reason for failure has been identified and corrected.
All costs will be for the suppliers account.

 

Quality Assurance
