Working sequence

AMS filing and why it must precede vessel loading

Most problems with ams pre-loading filing show up before the booking is confirmed. Here is the order our Shenzhen team works through it.

Before the booking: carrier manifest transmission

The automated manifest system requires the carrier to transmit cargo details to US customs before the vessel departs the foreign port.

We put this in the booking file so the destination broker sees the same version we do.

At handover: shipper instruction quality

Shipper-supplied descriptions, weights, marks and consignee details feed that manifest, so an incomplete shipping instruction becomes a filing problem.

Timing matters here: the check has to happen while the shipment is still editable in our system.

After arrival: do-not-load outcome

A do-not-load response means the container stays at origin; correcting it after cutoff usually costs a full sailing cycle.

If anything changes at this point, we reissue the file rather than patching it by email.

The failure point we see most often: Sending vague cargo descriptions on the booking instruction and trying to amend them after the manifest is transmitted.

Have these ready before filing:

Commercial invoice and packing list with matching values and descriptions.
Classification, origin and any licence references used in the declaration.
Booking reference, transport document and the consignee’s broker contact.

Questions importers ask us

Who is responsible for getting this right on a China-origin shipment?

The shipper supplies accurate product and value data; Hovmar Logistics checks the file before submission and coordinates with the destination broker. We confirm the split in writing at booking.

Can Hovmar review this before the cargo leaves Shenzhen?

Yes. Send the commercial invoice, packing list and intended classification before cutoff and our customs desk will flag gaps while they are still easy to fix.
