SOCIAL SECURITY
These Regulations further amend the Social Security (Categorisation of Earnings) Regulations 1978 (S.I. 1978/1689). Paragraph 9 of Schedule 3 to those Regulations provides that where an employee is employed by a foreign employer, and his services are made available, after 6th April 1994, to a person with a place of business in the U.K. (the “host employer”), the host employer is responsible for payment of secondary Class 1 national insurance contributions for the employee. The principal effect of these Regulations is to provide that paragraph 9 of Schedule 3 only applies to employed mariners if their employment duties are performed wholly or mainly in category A, B, C or D waters. Those waters are excluded from the meaning of “sea” in regulations made, or treated as made, under section 85 of the Merchant Shipping Act 1995.
