(1) All agricultural lime materials sold, offered or exposed for sale shall have a label affixed to each package in a conspicuous manner on the outside thereof, a plainly printed, stamped or otherwise marked label, tag of statement, or in the case of bulk sales, a delivery slip, which contains the following information:

1. (a) Name and principal office address of the manufacturer or distributor;
2. (b) Brand or trade name of the material;
3. (c) The identification of the product as to the type of the agricultural liming material, such as limestone, hydrated lime, burnt lime, industrial byproduct, marl and shells;
4. (d) Net weight;
5. (e) The minimum percentage of calcium oxide and magnesium oxide and/or calcium carbonate and magnesium carbonate shall be expressed in the following form: Total Calcium (Ca)___%. Total Magnesium (Mg)___%.
6. (f) The minimum calcium carbonate equivalent (CCE) of agricultural liming material that is subject of the label. Calcium Carbonate Equivalent shall be determined by methods prescribed by the Association of Official Analytical Chemists.
7. (g) The classification of the fineness of the agricultural liming material that is subject of the label. The minimum percentages by weight of that agricultural liming material which will pass through United States Standard 20, 60 and 100 sieves shall also appear on the label.

8. (h) The classifications of the fineness of agricultural liming material, as set forth in this section, are the minimum percentages by weight which shall be able to pass through various sizes of United States Standard sieves to earn a particular classification:

   Classification Sieve Size Minimums Fine-sized 95% through a 20 mesh sieve

   60% through a 60 mesh sieve 50% through a 100 mesh sieve

   Medium-sided 90% through a 20 mesh sieve

   50% through a 60 mesh sieve 30% through a 100 mesh sieve

   Coarse-sized 80% through a 20 mesh sieve.

   20% through a 100 mesh sieve.

9. (i) The minimum ENV of the agricultural liming material that is subject to the label.
10. (j) ENV shall be calculated using the following formula: (% by weight passing 20 mesh sieve - % passing 60 mesh sieve) x 0.4 = A; (% by weight passing 60 mesh sieve - % passing 100 mesh sieve) x 0.8 = B; (% by weight passing 100 mesh sieve) x 1.0 = C (A + B + C) x Calcium Carbonate Equivalent divided by 100 = ENV
11. (k) The maximum percentage by weight of the moisture content of the agricultural liming material that is subject to the label. The actual moisture content of the agricultural liming material shall be no more than 10% greater than the percentage by weight of the moisture content expressed on the label.
12. (l) The information required under 330 CMR 15.04(1)(e), (f), (i), and (j), (relating to elemental calcium and magnesium; CCE; and ENV) shall appear on the label under the heading "Guaranteed Dry Weight Analysis." The guaranteed dry weight analysis on a label shall be deemed deficient if testing of the agricultural liming material that is subject of the label shows that the actual analysis falls below the guaranteed dry weight analysis and any allowed tolerance with respect to any representation required to be set forth on the label by M.G.L. c. 128 or 330 CMR 15.00.

(2) Tolerances.

1. (a) A tolerance of 2% of the guaranteed minimum shall be allowed with respect to guaranteed minimum CCE and minimum fineness.
2. (b) A tolerance of 10% of the guarantee shall be allowed with respect to any other analysis required to be set forth on a label by 330 CMR 15.00.
