Bulk containers · BK codes

BK codes describe bulk containers, separately from portable-tank T instructions. A listed code alone does not establish acceptance for sea transport. Check the applicable DGL entry, chapter 4.3 and container requirements in chapter 6.9.

4.3.2.2 · Applicable additional provision

4.3.2.2 Bulk goods of class 4.3 Only closed bulk containers (BK2) may be used. These goods shall be transported in bulk containers which are waterproof.

Major defects include: .1 bends, cracks or breaks in the structural or supporting members that affect the integrity of the container; .2 more than one splice or an improper splice (such as a lapped splice) in top or bottom end rails or door headers; .3 more than two splices in any one top or bottom side rail; .4 any splice in a door sill or corner post; .5 door hinges and hardware that are seized, twisted, broken, missing, or otherwise inoperative; .6 gaskets and seals that do not seal; .7 any distortion of the overall configuration great enough to prevent proper alignment of handling equipment, mounting and securing chassis or vehicle, or insertion into ships’ cargo spaces; .8 any damage to lifting attachments or handling equipment interface features; or .9 any damage to service or operational equipment.
