Chemical import documents, Singapore: licence then permit

Most cargo pages are about documents. This one is about a document and a clock, and the clock is the half that surprises people.

A chemical import carries the ordinary pack: invoice, packing list, bill of lading, certificate of origin. Then it carries a set the regulation adds. What makes it a different job from importing steel or rice is that the extra documents are gating rather than supporting. Without them the permit does not go in, and while the permit is not in, the box is standing somewhere that charges by the day at a rate set for cargo nobody wants parked.

The licence is the importer’s own, and it comes first

In Singapore the sequence is licence, then permit, then arrival, in that order. The first step is the one a supplier cannot help with.

Before a declarant submits an import permit to TradeNet, they have to check whether the goods contain an ingredient listed in Part I of the Second Schedule to the Environmental Protection and Management Act. If they do, the importer must hold a valid Hazardous Substances Licence issued by the Chemical Control and Management Department of the National Environment Agency, and that licence number goes into the Licence Number field of the permit application. The general exemptions sit in Part II of the same Schedule.

Singapore Customs states that permit applications are processed within five working days upon receipt of all required documents, and that an application is complete only when the trader holds the valid licence and any transport approval and has supplied the supporting documents. Read that carefully: the five days is the permit, once everything is in hand. The licence is a separate instrument the importer applies for and holds, and a consignment that sails against a licence somebody assumed was current is a consignment that waits.

This is the same shape as the plant quarantine import permit on agri commodities: the one document in the pack that is the importer’s own application, on the importer’s calendar, and therefore the one that gets forgotten because there is no counterparty to chase for it.

The free time is shorter, and sometimes it is zero

Here is the part that turns a paperwork delay into a large number.

Terminals do not give dangerous cargo the ordinary allowance. The published DP World tariff for Jebel Ali is the clearest illustration of the principle because it is a document rather than a negotiation:

A class 5 container is accruing a charge from the day it is discharged. There is no grace period in which to find a missing safety data sheet.

Two things follow. The first is that the last free day on a dangerous cargo has to be computed from that cargo’s own allowance, not from the desk’s habitual assumption about the port. The second is that the carrier’s free time is a separate clock from the terminal’s, set in your service contract, and an importer clearing a chemical late pays both, at rates neither of which is the one they budgeted.

Check the tariff for the terminal you actually clear at. Jebel Ali is quoted here because its schedule is published; the allowance at your terminal is a different number and it is also a published one.

Three documents that have to say the same thing

Beyond the licence, the chemical pack adds a small set with an unusual property: they are read by different parties, each of whom will stop the box for a different reason, and they must agree.

A dangerous goods declaration from the shipper and a container packing certificate from whoever packed the unit, both required for dangerous goods carried in packaged form under the IMDG Code. That Code is the IMO’s rulebook for the maritime transport of dangerous goods in packaged form, covering packing, container traffic and stowage with particular reference to the segregation of incompatible substances, and it is mandatory as an extension of SOLAS chapter VII.

A safety data sheet for each substance.

And the product code matched to the HS code in the permit, with container and seal numbers, plus the maximum quantity per trip in kilograms where the substance falls under the Hazardous Substances Regulations.

The failure mode is boring and it is the common one. The declaration says one UN number, the safety data sheet was issued for a slightly different grade, and the HS code on the invoice belongs to a third classification the supplier’s back office has always used. Each is defensible on its own. Together they are a query, and a query on a class 5 container is a query with a meter running.

What this costs an import desk

The arithmetic is the same as any other cargo, with less room in it.

Desk work runs about 2.2 hours a container, of which 30 to 45 minutes is supplier follow-ups and 45 to 90 minutes is document-pack preparation and checking. Document packs routinely run about eight days late against free time. On an ordinary container with ten free days, eight days of lateness is uncomfortable. On a class 8 container with three, it is already over. On a class 5 container with none, there was never a margin to spend.

That is why the chemical desk is the one where people build private spreadsheets and check them at night. The deadline is earlier than the habit, and the habit was formed on cargo that forgave it.

Where Docket sits

Docket does not classify your chemicals and does not apply for your licence. Classification is your own responsibility and the licence is your application to the authority.

What it does is treat the licence as a dated obligation from the moment the purchase contract is recorded, rather than as something remembered when the arrival notice lands. It chases the supplier for the dangerous goods declaration, the packing certificate and the safety data sheet on the channels the supplier already uses: email, then WhatsApp at 24 hours, SMS at 48, an AI voice call at 72. It reads the classification on each document against the others and against the contract, so a UN number that disagrees with a safety data sheet surfaces before the booking rather than at the gate.

Then it counts backwards. Every deadline in the pack derives from the last free day, and on dangerous cargo it derives from a shorter one. That is the job demurrage and detention software is for, and on this cargo it is doing it against a clock that starts earlier and charges more.
