{"data":{"id":"us/7-cfr-201.65","jurisdiction":"us","citation":"7 CFR 201.65","heading":"Noxious-weed seeds in interstate commerce.","body":"Tolerances for rates of occurrence of noxious-weed seeds shall be recognized and shall be applied to the number of noxious-weed seeds found by analysis in the quantity of seed specified for noxious-weed seed determinations in § 201.46, except as provided in § 201.16(b). Rates per pound or ounce must be converted to the equivalent number of seeds found in § 201.46, Table 1, Minimum weight for noxious-weed seed examination (grams). Some tolerances are listed in the following table. The number found as represented by the label or test (Column X) will be considered within tolerance if not more than the corresponding numbers in Column Y are found by analysis in the administration of the Act. For numbers of seed greater than those in the table, a tolerance based on a degree of certainty of 5 percent (P = 0.05) can be calculated by the formula, Y = X + 1.65√X + 0.03, where X is the number of seeds represented by the label or test and Y is the maximum number within tolerance.\nNumber represented by label or test Maximum number within tolerances Number represented by label or test Maximum number within tolerances Number represented by label or test Maximum number within tolerances\n(X) (Y) (X) (Y) (X) (Y)\n0 2 34 43 68 81\n1 2 35 44 69 82\n2 4 36 45 70 83\n3 5 37 46 71 84\n4 7 38 47 72 85\n5 8 39 49 73 86\n6 9 40 50 74 87\n7 11 41 51 75 89\n8 12 42 52 76 90\n9 13 43 53 77 91\n10 14 44 54 78 92\n11 16 45 55 79 93\n12 17 46 56 80 94\n13 18 47 58 81 95\n14 19 48 59 82 96\n15 21 49 60 83 97\n16 22 50 61 84 98\n17 23 51 62 85 99\n18 24 52 63 86 101\n19 25 53 64 87 102\n20 27 54 65 88 103\n21 28 55 67 89 104\n22 29 56 68 90 105\n23 30 57 69 91 106\n24 31 58 70 92 107\n25 32 59 71 93 108\n26 34 60 72 94 109\n27 35 61 73 95 110\n28 36 62 74 96 111\n29 37 63 75 97 112\n30 38 64 76 98 114\n31 39 65 78 99 115\n32 41 66 79 100 116\n33 42 67 80","path":["Title 7—Agriculture","Subtitle B—Regulations of the Department of Agriculture","CHAPTER I—AGRICULTURAL MARKETING SERVICE (STANDARDS, INSPECTIONS, MARKETING PRACTICES), DEPARTMENT OF AGRICULTURE","SUBCHAPTER K—FEDERAL SEED ACT","PART 201—FEDERAL SEED ACT REQUIREMENTS"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-7.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:24:01Z","sha256":"2e4075717a6917fde9da002bbd8fd5502b1228b9c660bb74fc6022f1d16915c0","source_id":"us-cfr","stale":true,"prev":"us/7-cfr-201.64","next":"us/7-cfr-201.66"},"notice":"GroundRules: Original legal text.
