\"\"D\u00e9clarations IATA : quantit\u00e9 nette ou masse brute ?<\/strong><\/h2>\n

Pourquoi les d\u00e9clarations IATA pr\u00eatent \u00e0 confusion<\/strong><\/h4>\n

L\u2019une des questions qu\u2019on me pose le plus souvent au sujet de l\u2019exp\u00e9dition de marchandises dangereuses est la suivante : comment dois-je remplir ma d\u00e9claration IATA<\/a> ?<\/strong> Comme vous le savez peut-\u00eatre, les renseignements requis sur une d\u00e9claration IATA comprennent notamment le num\u00e9ro ONU, la d\u00e9signation officielle de transport, la classe de danger, le groupe d\u2019emballage et l\u2019instruction d\u2019emballage.<\/p>\n

La majeure partie de la confusion que je rencontre concerne l\u2019indication correcte de la quantit\u00e9 de marchandises dangereuses sur les documents. Faut-il indiquer la quantit\u00e9 nette ou le poids brut de l\u2019emballage ? La r\u00e9ponse d\u00e9pend de quelques facteurs importants qui, s\u2019ils ne sont pas trait\u00e9s correctement, peuvent entra\u00eener une non-conformit\u00e9.<\/p>\n

Quantit\u00e9 nette c. masse brute<\/strong><\/h4>\n

Tout d\u2019abord, il existe une diff\u00e9rence importante entre les termes quantit\u00e9 nette<\/strong> et masse brute<\/strong>. La quantit\u00e9 nette<\/strong> est d\u00e9finie comme la masse ou le volume des marchandises dangereuses contenues dans un emballage, \u00e0 l\u2019exclusion de la masse ou du volume de tout mat\u00e9riau d\u2019emballage. Autrement dit, la quantit\u00e9 nette correspond uniquement \u00e0 la masse des marchandises dangereuses elles-m\u00eames.<\/p>\n

Exemple : nitrate d\u2019argent dans une bo\u00eete 4G<\/strong><\/h4>\n

Par exemple, supposons que vous placez 1 kg de nitrate d\u2019argent (UN 1493)<\/strong> dans une bouteille en plastique, elle-m\u00eame plac\u00e9e dans une bo\u00eete 4G. La quantit\u00e9 nette indiqu\u00e9e serait de 1 kg<\/strong>, soit uniquement le poids des marchandises dangereuses.<\/p>\n

En revanche, la masse brute<\/strong> correspond au poids total du colis tel qu\u2019il est pr\u00e9sent\u00e9 au transport. Dans notre exemple, la masse brute comprendrait les marchandises dangereuses, la bouteille en plastique et son bouchon, le ruban adh\u00e9sif ainsi que la bo\u00eete 4G. Alors, quelle quantit\u00e9 doit \u00eatre indiqu\u00e9e sur une d\u00e9claration selon I\u2019ATA ?<\/p>\n

D\u00e9claration de marchandises dangereuses : quantit\u00e9 nette ou masse brut<\/strong><\/h4>\n

L\u2019IATA est tr\u00e8s pr\u00e9cise quant \u00e0 la fa\u00e7on d\u2019indiquer la quantit\u00e9 sur une d\u00e9claration de marchandises dangereuses. \u00c0 la section 8.1.6.9.2 a)<\/strong>, il est indiqu\u00e9 que la quantit\u00e9 nette de marchandises dangereuses dans chaque colis, en volume ou en poids selon le cas, doit \u00eatre indiqu\u00e9e pour chaque article de marchandises dangereuses portant une d\u00e9signation officielle de transport, un num\u00e9ro UN\/ID ou un groupe d\u2019emballage diff\u00e9rent. Des abr\u00e9viations peuvent \u00eatre utilis\u00e9es pour pr\u00e9ciser l\u2019unit\u00e9 de mesure de la quantit\u00e9, par exemple \u00ab KG \u00bb ou \u00ab L \u00bb.<\/p>\n

Lorsque la masse brute doit \u00eatre utilis\u00e9<\/strong><\/h4>\n

Toutefois, dans certaines circonstances, il peut \u00eatre n\u00e9cessaire d\u2019indiquer la masse brute.<\/p>\n

Quantit\u00e9s limit\u00e9es et lettre \u00ab G \u00bb<\/strong><\/h4>\n

Pour les quantit\u00e9s limit\u00e9es lorsque la lettre \u00ab G \u00bb<\/strong> suit la quantit\u00e9 dans la colonne H<\/strong> de la Liste des marchandises dangereuses, la masse brute de chaque colis doit \u00eatre indiqu\u00e9 plut\u00f4t que la quantit\u00e9 nette, et la lettre \u00ab G \u00bb<\/strong> doit \u00eatre ajout\u00e9e apr\u00e8s l\u2019unit\u00e9 de mesure, sauf lorsque diff\u00e9rentes marchandises dangereuses sont emball\u00e9es ensemble dans le m\u00eame emballage ext\u00e9rieur.<\/p>\n

Par exemple, pour ID 8000, produits de consommation<\/strong>, la lettre \u00ab G \u00bb<\/strong> appara\u00eet apr\u00e8s 30 KG<\/strong> dans la colonne H, ce qui signifie que la masse brute doit \u00eatre indiqu\u00e9 sur la d\u00e9claration.<\/p>\n
