1. For the purposes of subheadings 480411 and 480419, ‘kraftliner’ means machine-finished or machine-glazed paper and paperboard, of which not less than 80 % by weight of the total fibre content consists of wood fibres obtained by the chemical sulphate or soda processes, in rolls, weighing more than 115 g/m² and having a minimum Mullen bursting strength as indicated in the following table or the linearly interpolated or extrapolated equivalent for any other weight.

2. For the purposes of subheadings 480421 and 480429, ‘sack kraft paper’ means machine-finished paper, of which not less than 80 % by weight of the total fibre content consists of fibres obtained by the chemical sulphate or soda processes, in rolls, weighing not less than 60 g/m² but not more than 115 g/m² and meeting one of the following sets of specifications:

1. (a) having a Mullen burst index of not less than 3,7 kPa·m²/g and a stretch factor of more than 4,5 % in the cross direction and of more than 2 % in the machine direction;

2. (b) having minima for tear and tensile as indicated in the following table or the linearly interpolated equivalent for any other weight:

   Weight (g/m2)	Minimum tear (mN)	Minimum tensile (kN/m)
   	Machine direction	Machine direction plus cross direction	Cross direction	Machine direction plus cross direction
   60	700	1510	1,9	6,0
   70	830	1790	2,3	7,2
   80	965	2070	2,8	8,3

   115	1425	3060	4,4	12,3

3. For the purposes of subheading 480511, ‘semi-chemical fluting paper’ means paper, in rolls, of which not less than 65 % by weight of the total fibre content consists of unbleached hardwood fibres obtained by a combination of mechanical and chemical pulping processes, and having a CMT 30 (Corrugated Medium Test with 30 minutes of conditioning) crush resistance exceeding 1,8 newtons/g/m² at 50 % relative humidity, at 23 °C.

4. Subheading 480512 covers paper, in rolls, made mainly of straw pulp obtained by a combination of mechanical and chemical pulping processes, weighing 130 g/m² or more, and having a CMT 30 (Corrugated Medium Test with 30 minutes of conditioning) crush resistance exceeding 1,4 newtons/g/m² at 50 % relative humidity, at 23 °C.

5. Subheadings 480524 and 480525 cover paper and paperboard made wholly or mainly of pulp of recovered (waste and scrap) paper or paperboard. Testliner may also have a surface layer of dyed paper or of paper made of bleached or unbleached non-recovered pulp. These products have a Mullen burst index of not less than 2 kPa·m²/g.

6. For the purposes of subheading 480530, ‘sulphite wrapping paper’ means machine-glazed paper, of which more than 40 % by weight of the total fibre content consists of wood fibres obtained by the chemical sulphite process, having an ash content not exceeding 8 % and having a Mullen burst index of not less than 1,47 kPa·m²/g.

7. For the purposes of subheading 481022, ‘lightweight coated paper’ means paper, coated on both sides, of a total weight not exceeding 72 g/m², with a coating weight not exceeding 15 g/m² per side, on a base of which not less than 50 % by weight of the total fibre content consists of wood fibres obtained by a mechanical process.
