asked the Secretary of State for Trade how many do-it-yourself blood pressure machines have been imported from the United States of America.
This information is not available. Machines for testing blood pressure are not separately distinguished in the Overseas Trade Statistics. Electro-diagnostic apparatus of all kinds—other than electro-cardiographs—fall within a single heading of the Standard International Trade Classification. Documents submitted to Her Majesty's Customs by individual traders may be insufficiently detailed to enable goods imported under this heading to be identified more precisely, an undue cost would be incurred in such an investigation.
