The Canadian Indalco aluminum welding consumables supplied by Mastership hold type approvals and quality certifications from major international bodies. In regulated industries — marine, rail, pressure vessels — certification is a precondition of acceptance. Certificates and mill test certificates (MTC) are available on request.

• ABS — American Bureau of Shipping: the mainstream requirement for US-flag owners, offshore platforms and structures.
• DNV — Det Norske Veritas: commonly specified for European merchant ships, offshore wind and high-spec marine engineering.
• LR — Lloyd’s Register: one of the oldest classification societies, standard across international shipping and yachting.
• BV — Bureau Veritas: common for European vessels and workboats.
• CCS — China Classification Society: for Chinese-flag vessels and cross-strait routes.
