Non‐tariff measures and United States' imports of CBERA‐eligible products
计算了1991年美国对《加勒比盆地经济复兴法案》合格产品进口中非关税措施的覆盖率，发现16%的产品受其影响，部分产品组覆盖率更高，非关税措施阻碍了美国进口，与法案的优惠初衷相悖。
Trade coverage ratios are calculated to assess the 1991 incidence of non‐tariff measures (NTMs) on imports of products eligible for duty‐free treatment under the United States’ Caribbean Basin Economic Recovery Act (CBERA). Overall, 16 per cent of all CBERA‐eligible products were found to be covered by one or more NTM. Corresponding figures for all eligible products exported from individual beneficiaries range up to 40 per cent. Much higher trade coverage ratios are found for individual product groups. NTMs constitute important deterrents to US imports of CBERA‐eligible products. Heavy reliance on NTMs counters the intent of the CBERA, namely to extend preferential treatment to exports from Caribbean Basin countries.
