The SCFIS (Europe service) is compiled through the
following process:
Step 1: Data collection
According to the SSE specification, sample companies
will, during 0:00-13:00 each Monday Beijing time,
transmit information from the executed bills of lading (B/
L) for voyages with actual departure time (ATD) between
0:00 last Monday and 24:00 last Sunday through the
application program interface (API) automation system.
Each B/L contains such information as B/L number
(unique), destination port, container volume by container
type and corresponding freight rate.
Step 2: Data pre-treatment
(1) Verifying the B/L information. SSE uses the manifest
data from Shanghai port to verify the information on each
reported B/L such as the name of the ship, voyage, and
ATD, and check whether the shipping schedule complies
with the criteria for inclusion. Non-compliant data are
excluded from index calculation.
(2) Checking for duplicated B/L records of liner and
freight forwarder. If the forwarder’s freight rate is lower
than the liner’s, the former will not be used.
(3) Removing outliers. SSE first screens out outliers
of the freight rates for 20’ containers and 40’ containers
by applying the Grubbs or Pauta tests, then for each
container type screens out the highest 10% and lowest
10% of the remaining freight rates from all sample
companies.
(4) Limiting over-representation. SSE caps the container
volume share of any single sample company by container
type at 50%. An over-represented sample company’s
container volume will be reduced to 50% by multiplying
the volume of each B/L with the same coefficient.
Step 3: Index Calculation
After the above steps:
(1) Calculating the average freight rate by container type.
The total freight rates of all remaining B/L divided by the
total container volume equals the average freight rate.
(2) Calculating the benchmarking price index by container
type. The average freight rate divided by the average
freight rate on the base date, and then multiplied by 1000
equals benchmarking price index by container type for the
current period.
(3) Calculating SCFIS (Europe service). The weighted
average of the benchmarking price index by container
type is the SCFIS (Europe service).

service) please refer to the Rules for Compilation of SCFI
based on Settled Rates (Provisional) published on SSE’s
