A fly ash shipment is technically simple and administratively fussy. The cargo is non-hazardous and easy to
carry; the paperwork is where first-time buyers lose two weeks. Here is the full set.
Classification
Fly ash is normally declared under HS code 2621.90 - other slag and ash. GGBS moves under
2618.00, silica fume under 2811.22 and finished blocks or bricks under 6810. Some destinations apply their own
sub-headings, so the exact code goes on the proforma invoice before anything is booked.
The document set
- Commercial invoice and packing list - values, terms, marks and numbers
- Bill of lading - original set or telex release, as your bank requires
- Certificate of origin - non-preferential, or FTA form where a duty concession applies
- Certificate of analysis - from an independent laboratory, lot by lot
- Pre-shipment inspection report - SGS, Intertek or a surveyor you nominate
- Marine insurance certificate - on CIF terms, normally 110 percent of invoice value
- MSDS and non-hazardous declaration - required by most lines before they accept the booking
- Fumigation or phytosanitary certificate - only where the destination demands it
Bulk shipments need two more
For gearless bulk cargo the master will want a shipper declaration and a
transportable moisture limit certificate. Fly ash can liquefy and shift if it is loaded too
wet, so this is a safety document, not a formality - expect the surveyor to test it independently.
What actually goes wrong
- The certificate of analysis names a different lot number to the bill of lading
- The origin certificate spells the consignee differently to the letter of credit
- The MSDS is missing, and the line refuses the booking three days before the laycan
All three are avoidable by having one desk prepare the whole set together, which is how we do it.
