Metal-bearing ash exporter in Bangladesh

Buying metal-bearing ash in Bangladesh

Metal-bearing ash is the zinc ash, dross and skimmings left by galvanising, die casting and metal remelting, sold on metal content for recovery. Some of it is hazardous waste under Bangladesh's Hazardous Waste and Ship-breaking Waste Management Rules, 2011, and a hazardous lot needs Department of Environment clearance and the importing State's written consent before it moves.

So the first question is status, not price. As a metal-bearing ash exporter in Bangladesh, Roptan never promises that a lot can be exported: we source from verified sellers, have a sample assayed, check the classification with the Department of Environment and your import papers, and quote only once the route is clear.

Kinds of metal-bearing ash

What to tell a metal-bearing ash exporter in Bangladesh

Material and source process

Name the residue and its process: galvanising, die casting or aluminium remelting. The process tells the Department of Environment and the lab what to test for.

Metal content by assay

State the minimum zinc or aluminium and who assays it. US trade statistics report metal content as the assay quantity without deductions.

Lead and cadmium

Set limits and ask for them in the assay. Enough lead or cadmium can make a zinc residue hazardous under Basel and change the whole route.

Form and moisture

Say dispersible ash or lumpy dross, and require it dry, in sealed bags or lined containers. Zinc ash and aluminium by-products give off flammable gas when wet.

Your import papers

Tell us your country's rule for these residues: an import permit, a Basel consent, or a statement that the lot is non-hazardous.

Classification, consent and shipping rules

The 2011 Rules

Bangladesh's hazardous waste rules require Department of Environment clearance before a hazardous substance is shipped, and list several zinc, lead and aluminium residues as hazardous wastes.

Basel Convention

A hazardous waste may not move until the importing State consents in writing, and the exporter must take back a movement that fails. Entries B1080 and B1100 list some zinc and aluminium residues as non-hazardous.

UN 1435 and UN 3170

Zinc ashes and aluminium smelting by-products are class 4.3 dangerous goods, which emit flammable gas when wet. They are declared to the line and packed dry.

Export Policy 2024-27

The policy does not list metal-bearing ash as prohibited or conditional, but that does not lift the hazardous waste rules. Roptan also checks gazette notices at quote time.

What moves the price of metal-bearing ash

• Assayed metal content: zinc or aluminium recovered by the buyer, usually against the metal price on an agreed date.
• Lead, cadmium and other contaminants, which can change the classification as well as the value.
• Clearance and consent: the time and paperwork a hazardous lot needs before it can move.
• Dangerous goods packing, handling and freight for class 4.3 material.

Lead times and delivery

We give no lead time, and none for clearance or consent either. The 2011 Rules want the clearance application filed at least 21 days before loading, and give the Department of Environment 21 days to issue the clearance or state why not. After that come the assay, your country's written consent where it is needed, and dangerous goods space on a vessel. Roptan confirms the dates and any minimum in the quote.

Buyers inside Bangladesh can order through Roptan where both sides hold what the 2011 Rules require for that lot. We deliver dry, in sealed bags, weighed at loading and on arrival, with the assay report, weighbridge slips and a VAT invoice (Mushak 6.3).

Buying metal-bearing ash for export

Only when the route is clear: the Department of Environment has classed the lot as non-hazardous, or has cleared it and your country has consented in writing. Then we quote FOB Chattogram under HS 2620. Papers usually include the invoice, weight list, bill of lading, certificate of origin, assay, dangerous goods declaration, and clearance and consent papers.

What we check for this order

• Classification firstBefore any quote, we take this lot's classification under the 2011 Rules to the Department of Environment, with its assay and source process.
• Assay of a lot sampleA sample from your lot is assayed for metal content, lead and cadmium, since those decide both value and status.
• Clearance and consent in handWhere a lot is hazardous, nothing is loaded until the clearance and your country's written consent are on file.
• Dry, sealed and declaredWe check that the lot is dry, in sealed bags or lined containers, and declared as dangerous goods where required.
