Grades of Brazil Nuts in the Shell
- U.S. No. 1 consists of well cured whole Brazil nuts in the shell which are free from loose extraneous and foreign material and meet one of the size classifications in §51.3501. The shells are clean and free from damage caused by splits, breaks, punctures, oil stain, mold or other means, and contain kernels which are reasonably well developed, free from rancidity, mold, decay, and from damage caused by insects, discoloration, or other means.
a) In order to allow for variations incident to proper grading and handling, the following tolerances are provided:
1) For defects of the shell. Ten percent, by count, may fail to meet the requirements of the grade, including therein not more than 5 percent for serious damage by split, broken or punctured shells, oil stains, mold or other means.
2) For defects of the kernel. Ten percent, by count, may fail to meet the requirements of the grade, including therein not more than 7 percent for serious damage by any cause: Provided, That not more than five-sevenths of the latter amount, or 5 percent, shall be allowed for damage by insects: Provided further, That included in this 5 percent tolerance not more than one-half of 1 percent shall be allowed for Brazil nuts with live insects inside the shell.
3) For loose extraneous and foreign material. One percent, by weight: Provided, That such material is practically free from insect infestation.
