Six calculators that refuse to guess.
Each one answers a question an exporter or a forwarder answers by hand every week — and each is a copy of arithmetic the product already runs, taken from the same file rather than written a second time. No account, no form, no upload. Nothing you type leaves your browser.
They also do the thing that is easy to claim and hard to show: where the figures you gave do not settle the answer, they say which figure is missing instead of filling the column.
Duty and licences
What the government is owed.
What an unmet advance authorisation costs today: the duty saved times the share still undischarged, with interest from the day the period ended. Discharge is taken at the lower of quantity and value, never the average — the error that sends an exporter to the issuing office believing they are complete.
IGST, or CGST plus SGST? It turns on the place of supply, and for transportation of goods that is the customer's location if they are registered and where the goods were handed over if they are not. Same lane, two different answers — and each one names the section of the IGST Act that decides it and the day that rule took effect.
What the carrier charges
Freight, priced the way it is billed.
Gross against volumetric for the same cartons by sea LCL, air, express and road groupage, all four at once — because the same pallets are 3,360 kg by sea and 560 by air. The divisor is a contract term rather than a constant, so every one of them is yours to state, and a blank one is named as unstated instead of defaulted.
Two different clocks: one runs while the box is still inside the port, the other while it is out in your yard. Separate free days, usually separate rates, and a container can be running up both in the same week for different reasons. Each container is worked separately, and the answer says which clock the money came off.
Spread freight, duty, port charges, the clearing agent's bill and detention across the lines of one shipment, and get the true cost per unit with the arithmetic printed under every figure. Duty is an input from your own bill of entry: this holds no tariff table and does not pretend to.
How many cartons actually fit in a 20', a 40' and a 40' high cube — by laying rectangles on the floor rather than dividing one volume by another, which overstates the load every time because cartons do not flow into corners. The rated payload is checked against the result, and the table says whether space or weight is binding.
Why these are free
Each one is the product's own arithmetic.
Not a simplified version, and not a second implementation. Every calculator here is copied from the file the product runs — the export obligation tool from the same function that ranks your authorisations, the chargeable weight tool from the one every freight invoice is audited against, the container tool from the engine that plans a real stuffing. That is deliberate: a free tool that computes the answer its own way eventually disagrees with the product, and the person who notices is the one who was evaluating us.
It also means the refusals are real. A blank interest rate is not nought. A divisor of zero is a data error, not a contract term. A freight line whose place of supply the facts do not settle gets a named refusal and no head of tax — because a tax figure invented to fill a column is the one number on an invoice nobody can defend, and it is the person filing the return who signs for it.
What each one cannot see, it says. The obligation tool cannot check that a shipping bill quotes the right authorisation number, which is the discrepancy most exporters meet at closure. The container tool does not know your road weight limit, which on a twenty-foot box of dense cargo binds long before the rated payload does. Naming those is not a weakness on a page whose whole argument is that guessing is the failure mode.
