This hub is your quick reference for destination-specific shipping requirements. Check your country section before enabling a new market or shipping a new product category. Each entry covers what customer information you need to collect, how duties work, and what to watch out for.
Brazil
Duty model: DDU. Your customer pays import duties and taxes at delivery. Portless does not prepay these on your behalf.
Required customer fields at checkout
Tax ID (CPF)
Accurate phone number. Brazilian customs contacts the recipient directly
Postal code
Declared value: Brazilian customs requires shipments to be declared at retail price, not cost of goods (COGs). If customs conducts a check, they will ask the customer to provide proof of transaction. This will show the retail price paid, so the customs declaration must match it. Declaring at COGS creates a mismatch that can trigger delays, penalties, or refused delivery.
Duty and tax rates
For orders declared under $50 USD (retail price): 60% import duty plus a state transit tax of approximately 17–28%, applied to the declared (retail) value. Set clear expectations with customers at checkout. Unexpected charges are the most common reason for refused deliveries in Brazil.
Discounts must be shown on the customs invoice. If an order was discounted, that discount needs to be documented in the shipment declaration. The declared value should reflect the actual discounted retail price the customer paid, matching their proof of transaction. If it isn't documented, customs may assess duties against the full, un-discounted retail price.
Heads up on delivery rates: Without a PRC (Personal Responsibility Code), the expected delivery success rate in Brazil is approximately 80%. Factor this into your pricing.
Canada
Shipments to Canada occasionally experience extended customs holds. If a Canada order stops updating after the first-mile scan, allow additional transit time before escalating. Contact our support team if there's no movement after 10 business days.
Chile
Chile applies a simplified VAT process (19%) to parcels under $500 USD, with no import duties. See the full requirements in our dedicated article:
South Korea
Required customer fields at checkout
Personal Customs Clearance (PCC) code. Format: the letter P followed by 12 digits (e.g., P240018349034)
Phone number
Full address including dong, building, gu/district, city, and 5-digit postal code
Full name in English
Tip: Providing the customer's name in Korean (Hangul) alongside the English name reduces the chance of a mismatch at customs.
Orders without a valid PCC code will not clear customs. Make this a required field in your checkout or order form before enabling the South Korea market.
Taiwan
Required customer fields at checkout
National tax ID number (format: one letter followed by nine digits, e.g. J122410303)
Full name in Chinese characters
Full address in Chinese
All three fields are mandatory. Portless cannot obtain or verify these on your behalf. If any are missing, the shipment will be blocked. Build these as required fields in your post-purchase or checkout flow before going live in Taiwan.
United States
Portless manages HTS code assignments through our customs broker. You don't need to specify these yourself. We review and update classifications proactively as tariff conditions change.
