Section 301 China lists: headings, rates, dates, counts (pay per call in USDC via x402, no key)

Every Section 301 heading in Chapter 99 (lists 1, 2, 3, 4A, 4B, the 2024 four-year-review increases and the exclusion headings) with the official rate text, effective dates and how many codes each covers.

Pay per call with x402: $0.012 per call in USDC on Base. No key, no account: an unpaid call returns 402 with the payment requirements; retry with the X-PAYMENT (x402 v1) or PAYMENT-SIGNATURE (v2) header.
