TotalInvoice includes several fields a basic invoice template doesn’t: destination-specific HS codes, material composition, Incoterms, Nature of Transaction Code, Shipper’s EORI, Shipper’s EIN\/CAIN, the US Manufacturer Identification Code (MID), and the manufacturer’s name and address. None of these were added for show \u2014 each one exists because a real customs regulation requires or expects it on a commercial invoice, and getting it wrong (or leaving it out) is a common, documented cause of shipments being delayed, re-assessed for duty, or held at the border.<\/p>\n\n\n\n
This page sets out, field by field, which regulation is behind it and why it matters in practice. It’s background information, not legal advice \u2014 customs rules vary by country and change over time, so always confirm current requirements for a specific shipment with a licensed customs broker.<\/p>\n\n\n\n
Basis:<\/strong> the World Customs Organization’s Harmonized System, adopted into national tariff schedules worldwide (e.g. the US Harmonized Tariff Schedule); US customs invoice content rules are set out in 19 CFR 141.86. Basis:<\/strong> 19 U.S.C. \u00a71304 and 19 CFR Part 134 in the US (most countries have an equivalent marking\/declaration requirement). Basis:<\/strong> in the US, the Textile Fiber Products Identification Act (15 U.S.C. \u00a770 et seq., implemented at 16 CFR Part 303) requires fibre content to be disclosed on the product itself; composition also directly affects HS classification, since many tariff lines are defined by material. Basis:<\/strong> the International Chamber of Commerce’s Incoterms rules \u2014 not government law, but referenced throughout customs and shipping documentation worldwide. Basis:<\/strong> a required data element of the Electronic Export Information filed under the US Foreign Trade Regulations, 15 CFR Part 30. Basis:<\/strong> the EU’s Union Customs Code (Regulation (EU) No 952\/2013), and \u2014 since Brexit \u2014 equivalent UK customs rules enforced by HMRC. Basis:<\/strong> formal US customs entries (broadly, shipments of $2,500 or more in goods value) require the Importer of Record to be identified with a US tax ID (an EIN) or a CBP-assigned CAIN, under US entry regulations (19 CFR Parts 142\u2013143). Basis:<\/strong> 19 CFR 102.21(b)(5) and US Customs’ own MID construction rules (19 CFR Part 102, Appendix).
Why it matters:<\/strong> the HS code determines the duty rate charged at the border. The right code for one destination country isn’t always right for another \u2014 a mismatch is one of the most common causes of customs delays and unexpected duty bills.<\/p>\n\n\n\nCountry of origin<\/h3>\n\n\n\n
Why it matters:<\/strong> determines the duty rate applied, whether a trade agreement reduces or removes duty, and in some cases whether the goods are admissible at all.
Where TotalInvoice gets it:<\/strong> Shopify’s own native “Country\/Region of origin” field, set per product variant under Inventory \u2014 the same field Shopify’s own Managed Markets duty estimates use. Nothing extra to configure if it’s already filled in.<\/p>\n\n\n\nMaterial composition<\/h3>\n\n\n\n
Why it matters:<\/strong> beyond the product-labelling requirement, customs can reclassify \u2014 and re-duty \u2014 a shipment if the stated composition doesn’t match the HS code used on the invoice.<\/p>\n\n\n\nIncoterms<\/h3>\n\n\n\n
Why it matters:<\/strong> defines who is responsible for duties, risk and paperwork at each stage of the shipment \u2014 and specifically, under DDP terms, who is treated as the Importer of Record for customs purposes (see Shipper’s EIN\/CAIN below).<\/p>\n\n\n\nNature of Transaction Code<\/h3>\n\n\n\n
Why it matters:<\/strong> tells customs and trade-statistics authorities what kind of transaction is taking place \u2014 a sale, a gift, a return, and so on \u2014 needed for accurate export reporting.<\/p>\n\n\n\nShipper’s EORI number<\/h3>\n\n\n\n
Why it matters:<\/strong> every customs declaration into or out of the UK or EU must carry a valid EORI identifying the trader responsible for the goods. Without one, a shipment cannot clear customs at all.<\/p>\n\n\n\nShipper’s EIN or CBP-assigned CAIN<\/h3>\n\n\n\n
Why it matters:<\/strong> under DDP terms the shipper is usually the Importer of Record \u2014 meaning it’s the shipper’s number that must appear, not the buyer’s. Without it, a formal entry can’t be filed.<\/p>\n\n\n\nManufacturer Identification Code (MID)<\/h3>\n\n\n\n
Why it matters:<\/strong> required on formal US entries for textile and apparel goods. It’s a short, encoded identifier that CBP’s own electronic filing systems (ABI\/ACE) use to track a given manufacturer consistently across entries \u2014 an entry can be rejected at filing without a correctly-built one.<\/p>\n\n\n\nManufacturer’s name and address<\/h3>\n\n\n\n
