There are no classes, so no reason to import it as there's nothing to assign to hosts.  The custom types and providers are usable from manifests without classes or importing of classes.

So how am I to install custom types in Satellite 6 environment? I can't find any documentation describing how to do that.

Just add the modules to a content view, there's no need to see Puppet classes imported or link them to hosts.

Sorry, I should've been more clear. 

pulp-puppet-module-builder ignores the module, duritong/sysctl and blentz/selinux_types are both modules of this sort from puppet forge.

Reproducer steps :
1) Install the module from puppet forge
[root@sdodson-sat6 modules]# puppet module install duritong/sysctl
Notice: Preparing to install into /etc/puppet/modules ...
Notice: Downloading from https://forgeapi.puppetlabs.com ...
Notice: Installing -- do not interrupt ...
/etc/puppet/modules
└── duritong-sysctl (v0.0.5)
[root@sdodson-sat6 modules]# cd /etc/puppet/modules/
[root@sdodson-sat6 modules]# ls
concat  haproxy  keepalived  lokkit  motd  ntp  openshift_origin  selinux_types  stdlib  sysctl

2) run pulp-puppet-module-builder, it fails to pickup sysctl module and build a tarball for it, which means that when I sync the puppet repository via satellite UI it of course fails to import the module.

[root@sdodson-sat6 modules]# pulp-puppet-module-builder --output-dir=/modules 
cd /etc/puppet/modules
git status
find . -name init.pp
puppet module build ./ntp
mkdir -p /modules
cp ./ntp/pkg/puppetlabs-ntp-3.1.2.tar.gz /modules
puppet module build ./lokkit
mkdir -p /modules

cp ./openshift_origin/pkg/openshift-openshift_origin-4.0.11.tar.gz /modules
cp ./openshift_origin/pkg/openshift-openshift_origin-4.0.12.tar.gz /modules
puppet module build ./motd
mkdir -p /modules
cp ./motd/pkg/puppetlabs-motd-1.1.1.tar.gz /modules
puppet module build ./concat
mkdir -p /modules
cp ./concat/pkg/puppetlabs-concat-1.1.1.tar.gz /modules
cd /modules
cd /etc/puppet/modules
cd /etc/puppet/modules

It also fails if I try to upload the module to the repo via the UI, but that may be bug 1142301  The module I'm trying to upload is https://forgeapi.puppetlabs.com/v3/files/duritong-sysctl-0.0.5.tar.gz
