How to target part of product description?

[lanmi123]

I'm trying to translate the shipping section in my product description based on country and locale.

I already figured out how I can check for the country (localization.country.iso_code) and locale (request.locale.iso_code), but now I'm having issues targeting the part of my product description regarding shipping.

In main-product.liquid I have this part which is interesting to me:

{%- form 'product', product, class: 'ProductForm' -%}
    {%- render 'product-data', product: product -%}

    {%- for block in section.blocks -%}
      {%- case block.type -%}
        {%- when '@app' -%}
          {%- render block -%}

        {%- when 'product_meta' -%}
          {%- render 'product-meta', form: form, block: block, product: product -%}

        {%- when 'description' -%}
          {%- if product.description != blank -%}
            <div class="ProductMeta__Description" {{ block.shopify_attributes }}>
              <div class="Rte">
                {{- product.description | replace: 'data-section-type', 'data-section-type-placeholder' -}}
              </div>
            </div>

My idea was to check for language and locale there, but I'm having issues targeting shipping, since the generated code for product.description looks like this:

<div class="ProductMeta__Description">
    <p>Product Number One</p>
    <p>Produt Number One Info</p>
    <p data-mce-fragment="1">Dimensions...</p>
    <p data-mce-fragment="1">Volume...</p>
    <h5 data-mce-fragment="1">Fabrics...</h5>
    <h5 data-mce-fragment="1">SHIPPING</h5>
    <p data-mce-fragment="1">Shipping info</p>
</div>

How can I set up my liquid code to achieve the the following but have only the shipping info change:

{%- if request.locale.iso_code == 'en' -%}
  {%- if localization.country.iso_code == 'US' -%}
    <div class="ProductMeta__Description">
      <p>Product Number One</p>
      <p>Produt Number One Info</p>
      <p data-mce-fragment="1">Dimensions...</p>
      <p data-mce-fragment="1">Volume...</p>
      <h5 data-mce-fragment="1">Fabrics...</h5>
     <h5 data-mce-fragment="1">SHIPPING</h5>
    <p data-mce-fragment="1">US Shipping info</p>
</div>
  {%- elsif localization.country.iso_code == 'JP' -%}
...

This will change the English translation only for Product Number One, for US market only. I would have to do it for each product, for each country and for each locale.

Is there a way to select only the shipping section in product.description? 
Ideally my could would look like this:

{%- when 'description' -%}
  {%- if product.description != blank -%}
    <div class="ProductMeta__Description" {{ block.shopify_attributes }}>
      <div class="Rte">
        {%- if request.locale.iso_code == 'en' -%}
          {%- if localization.country.iso_code == 'US' -%}
            <h5>Shipping</h5>
              Custom US shipping info.
       {%- elsif -%}
         {{- product.description | replace: 'data-section-type', 'data-section-type-placeholder' -}}
      </div>
    </div>
