Sodium nitrate seaborne export process and precautions

Sodium nitrate, also known as "Chilean nitrate". The chemical formula NaNO3. Molecular weight 84.99. Hygroscopic colorless transparent triangular crystals. Melting point 306.8 °C, relative density 2.26. Decomposes when heated to 380 °C. It is very soluble in water, liquid ammonia, soluble in methanol and ethanol, very slightly soluble in acetone, and slightly soluble in glycerol. When dissolved in water, it absorbs heat, the solution becomes cold, and the aqueous solution is neutral. Nitrogen oxides are absorbed by alkali solutions for industrial production, and then evaporated and crystallized. It is used for the preparation of nitric acid, sodium nitrite, catalyst preparation in the sulfuric acid industry, etc.

Let's talk about the process and precautions for the export of sodium nitrate by sea

First, the use of the product

1. It is a raw material for the manufacture of potassium nitrate, mine explosives, dyes, etc. Nitrifying agent for the manufacture of dye intermediates.

2. Nitrates have early strength effects, especially at low temperatures and negative temperatures as early strength and antifreeze. It is also a raw material for the manufacture of potassium nitrate, mine explosives, picric acid and dyes. Nitrifying agent for the manufacture of dye intermediates

3. Used as an analytical reagent, such as an oxidant. It is also used to synthesize dyes, drugs, and make fireworks and explosives

4. Used in enamel, glass, dye industry, medicine, agriculture as fertilizer

Second, sodium nitrate seaborne export packaging form

Standard industrial sodium nitrate is packaged in a double-layer package with a polyethylene plastic film bag on the inside and a plastic woven bag on the outer packaging with a net content of 25kg or 50kg per bag. The standard packaging of the product, the film bag is tied twice with a vinylon rope or a rope of comparable quality, or sealed in another way equivalent to it; the outer bag is folded at no less than 30 mm from the bag edge, and the vinyllon thread or other thread of equivalent quality is used at no less than 15 mm from the bag edge. The stitches are neat and the needle spacing is uniform. No leaks and jumpers.

Third, sodium nitrate maritime export land transport precautions

Whether it is a warehouse or a factory trailer to pick up goods, sodium nitrate should have a cover during land transportation to prevent rain and moisture. When storing, it should be stored in a ventilated, dry warehouse. Rain and moisture should be prevented, and direct sunlight should be avoided. Co-transport and co-storage with acids, metal powders, wood chips, gauze, paper, sugar, sulfur and other organic flammable substances and reducing substances should be avoided. When handling and palletizing, it should be handled lightly to prevent friction and impact, and the spacing between stacks and stacks, stacks and walls should be maintained at 0.7m-0.8m.

Fourth, sodium nitrate seaborne export basic information

Un Correct Transport Name (Chinese): Sodium Nitrate

Un Correct Shipping Name (English): Sodium nitrate

Main Hazard Category: 5.1

UN Code: 1498

Packaging category: III

HS:3102500000

Ems NO:F-A,S-Q

5. Documents required for the export of sodium nitrate by sea

5.1 Category dangerous goods as a high risk of high risk must be strictly in accordance with the dangerous goods channel booking declaration for export, the information documents required for export are:

1. Booking

Booking power of attorney: In addition to the consignor and consignee information, the most important thing is to describe the gross weight, net weight and packaging form of the single piece, and the number of inner packages

(Note that the dangerous goods export booking needs to be ten days in advance, and the dangerous goods booking data must be accurate and cannot be changed)

2. English MSDS

English MSDS (shipowners will focus on physical and chemical characteristics and transportation items, which characterize the shipowner's transportation naturally knows how to focus on operation in transportation)

With a power of attorney and MSDS, you can book a dangerous goods space. MSK HPL MSC HMM KMTC and other shipping companies have done a good job in the approval of class 5.1 dangerous goods, and the approval time is still relatively fast, and generally two working days can be provisioned. You can see a lot of information above, the port of departure, the port of destination, the port of transit, the number of pieces, the weight, the volume, the opening date, the ship name voyage, the bill of lading number interception declaration time, etc.

Because the 5.1 class of dangerous goods belongs to the high-risk category, there are not many shipping companies to pick up, and the shipping companies that can pick up also depend on the requirements of the co-cabin mother ship and the route, and if it is a two-way ship, it also depends on the situation of the two-way mother ship and so on.

3. Dangerous package certificate

(Mainly contains performance certificates and use certificates, performance sheets are relatively simple, generally can make regular packaging manufacturers can provide, but the use of certificates is more complicated, need to cooperate with IMI identification and performance list to the factory local commodity inspection bureau application).

5.1 Class of dangerous goods for sea export must provide the original dangerous package certificate, no dangerous package certificate can not be exported, you need to provide a dangerous package certificate 10 working days in advance, the cargo detailed data support, submitted to the shipowner for review.

4. Commodity inspection form

Since the HS of sodium nitrate is 31025000000, which is a product of statutory inspection, sodium nitrate must be inspected by the service provider in the seaborne export, that is, the electronic bottom account. Note that the commodity inspection header must be consistent with the customs declaration header.

5. Preparation of transportation and packing is an important part

Shanghai is divided into outer ports and Yangshan, the outer port is an advanced port after customs declaration, Yangshan is the first customs declaration and then into the port, the dangerous goods plan is also accepted separately, rather than according to the port opening plan of the wharf (such a foreign port part of the wharf needs to enter the dangerous warehouse, Yangshan needs to be directly loaded)

Difficulties: There are very few dangerous goods warehouses that can be professionally and regularly qualified to operate the 5.1 dangerous goods boxing, and there are very few warehouses that can be formally connected, and the loading and unloading of products need special attention and care. In order to ensure the safe premise of smooth operation of the packing of goods, the master worker should be very careful, do not paralyze the carelessness of the leak, the impact of the shipment is small, safety issues must be paid attention to.
